INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000 AND 800with concrete bearing ring and standard cover (BEGU)

The bearing area of the chamber base should be prepared as per

DIN EN 1610. To do this, construct a min. 10 cm thick bedding layer

(e.g. granular subbase).

Set the chamber base at the relevant height according the plans,

align and position in accordance with the connecting pipes. Ensure

that the chamber drainage channel is not laid with a counter slope. Fit

the chamber base outlet onto the pipe using lubricant.

Push-fit connection: Apply lubricant to the spigot, check that the seals

are correctly positioned before fitting and clean oT any dirt. Push pipe

and chamber together up to the stop.

Fit the articulated socket/ball joint (included as standard with the

chamber base if necessary) onto the inlet side of the chamber base.

Follow the instructions given on the sockets for direction-bound

sockets/ball joints. Observe the notes on the push-fit process, see

point 2. When fitting the ball joint DN 160/DN 200, note the flow

direction, marked with embossed arrows. Stabilise the chamber base

on the side as necessary using bedding material.

Push the pipe into the chamber base on the inlet. Observe the

notes on the push-fit process, see point 2. Then align the pipe in

accordance with the pipeline routing. The articulated sockets and ball

joints can be used to realise slope changes as well as changes in

direction up to 7.5° to the left or right. With a simultaneous change in

slope and direction, the deflection values can be reduced.

Note on installing the articulated sockets:

The articulated sockets should be inserted onto the chamber base

with the fully variable side. Also, ensure that the soZt marking is

pointing upwards (see sketch). The assembly notes on the jointed

socket must be observed:

To connect the chamber elements, first coat the top sealing

chamber with lubricant. This makes it easier to stretch out the

chamber element seal and ensures that the fitted position is correct.

232

Insert the element seal into the sealing chamber with the lettering

pointing upwards and then check for damage and correct position and

for any dirt.

Clean the socket on the chamber ring being installed and coat it

evenly with lubricant. (Installation tip: do not coat the seal with

lubricant.) Ensure that there is no dirt on the socket after being coated

with lubricant.

Position the chamber elements on top of one another without

tilting. Positioning the chamber rings and chamber cone is made

easier by the 4 external retaining lugs. Align the chamber elements

with one another using the two external longitudinal marks to ensure

the correct positioning of the vertical ladder. Then push the compo-

nents all the way together.

To fill the chamber components, soil of group G1 or G2, max.

particle size 63 mm (stepped soil with fine particles) should be used.

Recommendation: Use recycled material. Add back-fill material at

a width of 40 cm (for installation of the chambers in groundwater min.

60 cm) carefully and in layer thicknesses of 20 to 40 cm and compact

in line with the stipulations of DIN EN 1610, ATV-DVWK-A 139.

Degree of compaction in the area of roads DPr ≥ 97 %.

In the same way as points 5 to 8, fit further chamber rings or

chamber cones, then add backfilling material in layers and compact

in accordance with point 9.

233

The chamber cone is delivered to the site unshortened and must

be shortened on site for the access opening. The dimension for

shortening depends on the installation depth of the chamber structure

and the choice of the chamber cover. Maximum shortening dimension

25 cm. Trimming is carried out in line with the rib bases, which are

spaced at intervals of 1 cm. Deburr the cut edge. To calculate the

shortened dimension, see installation sketch on page 235.

The filling/bedding of the chamber is carried out up to 5 cm below

the upper edge of the trimmed cone (OKgK) (see installation sketch on

page 235). The embedding surface must be level and must not

transmit any point loads to the concrete bearing ring (add fine grit or a

mortar layer if necessary).

Fit the cone seal DN 625 flush to the top edge of the shortened cone.

Coat the inside of the concrete bearing ring with lubricant and then

mount centrically. To ensure that he concrete bearing ring is evenly

mounted, without impairing the prepared fine layer, the use of

screw-in rope loops (accessories) is recommended. The concrete

bearing ring transmits the traZc loads on to the road foundations. The

concrete bearing ring must be seated solidly and evenly. Point loads

should be avoided (see point 12). Direct load contact between the

concrete bearing ring and the chamber cone should also be avoided.

This is ensured by creating approx. 5 cm of overlap between the

chamber cone and the concrete bearing ring (see installation sketch

dimension hU).

A vertical interval of approx. 4 cm must be maintained between

the upper edge of the cone and the concrete bearing ring. This

ensures that after any potential settlement of the road structure, the

traZc load is not transferred directly into the chamber.

Note: During the road building phase, insert steel cover plate or similar

into the concrete bearing ring in order to cover the chamber.

Point loads between the concrete bearing ring and the cover

should be avoided. To do this, set the cover on a 1 cm thick layer of

levelling mortar. See installation sketch below.

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000 AND 800with concrete bearing ring and roll-in cover

– Installation steps 1 – 15 see “Installation instructions for

AWASCHACHT PP DN 1000 and 800 with concrete bearing ring and

standard cover (BEGU)“ on page 232.

To install the roll-in cover, observe the installation instructions from

the relevant cast iron manufacturer. If an adapter ring is required for

the chosen roll-in cover, set this on a 1 cm thick layer of levelling

mortar. See installation sketch below.

Installation of the cast cover using the example of the VIATOP

NIVEAU 200: Insert chamber cover with frame. In the fully installed

condition, there must be min. 2 cm space between the cast frame

and concrete bearing ring or adapter ring. Where necessary, cover the

gap between the adapter ring and frame with a bitumen layer to

prevent mixture falling in. Line the flange with mixture and bring it to

roughly the final level of the first layer.

Mark the position of the cover and apply the first surface course.

Where necessary, scatter fine sand onto the cover to facilitate

subsequent cleaning.

To ensure the same compaction for rolling-in as in the surrounding

area, the frame should be raised with a pickaxe to approx. 20 % of

the layer thickness above the final level. Line with mixture again and

add a second layer.

Press the cover down by rolling over it several times in the centre

and finish rolling-in as part of the total surface compaction.

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000 AND 800with concrete cover plate

– Installation steps 1 – 9 see “Installation instructions for

AWASCHACHT PP DN 1000 and 800 with concrete bearing ring and

standard cover (BEGU)“ on page 232.

In the same way as points 5 to 8, fit further chamber rings or

chamber cones and then add backfilling material according to point 9

in layers and compact.

The chamber rings are supplied unshortened to the construction

site. Depending on the installation depth of the chamber, the chamber

ring must be shortened by 125 mm as necessary. The shortening

process is carried out between the two marking lines above the

sealing chamber. See also point 15.

The chamber ring and cover plate must overlap by approx. 70 mm

to max. 90 mm to ensure the seal and correct load distribution. Create

a fine grit layer or concrete foundation accordingly. See installation

sketch on page 238.

Check the chamber element seal for damage and correct fit and

clean away any dirt. Coat the concrete cover plate on the sealing

surface with lubricant.

Raise the concrete cover plate horizontally and centrally over the

chamber ring and place it onto the prepared subsoil. The access

opening should be aligned with the ladder rungs. If mounted correctly,

there should be a gap of 30 – 50 mm inside the chamber between

the top edge of the chamber ring and concrete cover plate.

Depending on the installation height of the existing chamber cover,

concrete compensating rings of diTerent heights should be fitted for

adjustment to the GOK if necessary. With a very high / excessively

low levelling height, it is necessary to shorten the chamber ring in

advance by exactly 125 mm (see point 11). Then fit concrete

compensating ring(s) and chamber cover on the levelling mortar layer.

The number of concrete compensating rings for height equalisation

should be kept to a minimum.

Installation instructions AWASCHACHT PP DN 1000 in liquid soil

When installing the AWASCHACHT PP DN 1000 in liquid soil, note

that installed components have a strong buoyant force. This buoyant

force remains until the liquid soil started hardening. To prevent the

location of the chamber bases put into position due to the backfill with

liquid soil, an additional load must be applied that is higher than the

buoyant force. The counterweight depends on the backfill height.

The buoyant force of the AWASCHACHT PP DN 1000 in liquid soil is

around twice as strong as in water.

At least 185 kg of additional load should be applied to the chamber/

chamber base per 10 cm backfill height with liquid soil. Once the soil

started hardening, the next layer of liquid soil can be applied.

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000with chamber bases DN 1200/1500

– See “Installation instructions for AWASCHACHT PP DN 1000

and 800 with concrete bearing ring and standard cover (BEGU)“ on

page 232.

To fill the chamber base DN 1200/DN 1500, soil of group G1 or

G2, max. grain size 32 mm (stepped soil with fine particles) should be

used. Recommendation: Use recycled material. Add back-fill material

at a width of 40 cm (for installation of the chambers in groundwater

min. 60 cm) carefully and in layers in chamber thicknesses of 20 to

40 cm and compact in line with the stipulations of DIN EN 1610,

ATV-DVWK-A 139.

Degree of compaction DPr 97 %.

The compaction of the back-fill soil must be implemented up to the

height of the adapter plate (1 to 2 cm below) between the chamber

base and chamber ring. See installation sketch on page 268. See

installation sketch on page 240.

The embedding surface for the reinforced concrete load distributi-

on plate must be level and must not transmit any point loads.

To do this, an approx. 20 cm wide layer of fine grit (sand if necessary)

should be applied where the surface is at the same height as the top

of the adapter plate.

Note: In order to create exactly the right level, the fine grit layer can be

removed with a batten to the height of the polymer adapter plate.

The delivery scope includes a square seal for the external

circumference of the adapter plate as well as a seal along the

circumference of the ascending chamber rings DN 1000. Carefully

clean the adapter plate and then glue on the two square seals. The

seals may already be glued onto the underside of the load distribution

plate.

239

Carefully place the reinforced concrete load distribution plate onto

the fine grit layer using ring bolts.

Caution! Ensure that the load distribution plate is correctly rotated so

that it does not rest on the polymer adapter plate.

Fill the gap between the reinforced concrete load distribution plate

and chamber ring DN 1000 with mortar.

– Implement the remaining installation steps in accordance with

point 5 T. of the “Installation instructions for AWASCHACHT PP DN

1000 and 800 with concrete bearing ring and standard cover (BEGU)”

on page 232.

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000Description for constructing the AWASCHACHT PP DN 1000

General

When calculating the installation depths, the diTering eTective heights of the chamber base, chamber rings, chamber cone, bearing ring,

chamber cover and where appropriate the levelling mortar layer should be taken into account. Observe the installation instructions.

ETective height of chamber base: The eTective height relates to the centre of the chamber base. For each 1 % slope in the drainage channel,

the inlet/outlet are 5 mm higher/lower. Other slopes accordingly.

ETective height of cone: The eTective height of the unshortened cone DN 1000/625 is 820 mm. When fully shortened, it is 570 mm.

The cone can be shortened in increments of 10 mm by up to 250 mm.

Note on the result:

The chamber ring is shortened by 125 mm. The diTerence between 125 – 30 = 95 must be realised on-site by the customer using compensa-

ting ring rings and levelling mortar.

** With a remaining height greater than 125 mm, a further chamber ring should be used.

With a remaining height between 0 mm and 125 mm, this should be realised using standard levelling rings.

With a remaining height between -125 mm and 0 mm, the customer should shorten the top chamber ring on site by exactly 125 mm and the height then adjusted using

standard compensating rings. Observe the installation instructions for AWASCHACHT PP DN 1000 and DN 800 with concrete bearing ring and standard cover (BEGU).

If no chamber rings are used, the remaining height must not be smaller than 0 (minimum installation depth reached).

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 1000 AND 800Chamber-in-chamber renovation method

Important: During all work steps, the relevant accident

prevention regulations should be observed.

Preparation: Measure the chamber and chamber base (height,

diameter, angle) and order the renovation chamber.

Remove the concrete chamber cone DN 1000/625.

Clean the concrete chamber rings and seal against penetrating,

flowing water as appropriate.

Stop the flow of wastewater. To do this, fit shut-oT bladders into

the outlets (tip: Fit shut-oT bladders in the next chamber (inlet side) to

facilitate work in the renovation chamber.)

Remove the climbing steps or step irons from the existing chamber.

The existing drainage channel and the existing berm are to be

chiselled out until the pipe sockets of the chamber-in-chamber (SiS)

chamber base are flush with the existing pipes. Ensure that the

chamber base plate is not chiselled out too far down to avoid potential

ingress of groundwater.

NOTE: Stop acute water ingress by appropriate means (e.g. plugging

mortar OMBRAN W). This temporary seal must function until the

mortar has set in the ring gap (see step 15).

Fit the chamber element seal onto the chamber base. To fit the

chamber element seal, first coat the top sealing chamber with lubricant.

Then insert the element seal into the sealing chamber with the

lettering pointing upwards and check for damage and correct position,

and for any dirt.

245

Mount the Q-TE-C expandable seals. Install the blue-green round

cord seals supplied onto the pipe sockets on the renovation chamber

base. Position the seals behind the bead to avoid rolling away.

Lower the renovation chamber base into the concrete chamber.

Check the fit of the renovation chamber base with the connection

pipes (flow height and angle). If necessary, line the existing drainage

channel further or raise the SiS chamber base. The drainage channel

base of the chamber base must be at the same height as the existing

pipe bottom.

Position shut-oT bladders on every inlet and outlet. These are

used to centre the connection socket of the new chamber drainage

channel with the existing pipes and as shuttering for the grout.

When inflating the shut-oT bladders, align the renovation chamber

base horizontally using a spirit level.

Note: If the existing chamber is in a skew position, the SiS chamber

base also has to be slanted in order to ensure an even ring gap for

further chamber construction.

Fit at least 3 steel brackets to the wall as buoyancy control for the

filling process. Ensure that these are distributed evenly across the

circumference of the renovation chamber base.

246

Mix a quick-setting, wastewater resistant grouting mortar (e.g.

OMBRAN FG plus) according to the manufacturer’s specifications and

pour it into the gap between the concrete chamber and the renovation

chamber base via a chute. Pour the mortar in from one side and

without interruption until the highest shut-oT bladder is embedded in

mortar at least 5 cm.

CAUTION! In order to ensure that the chamber rings can be inserted

with a socket, the grouting must have a minimum circumferential

distance to the top rib of the spigot end from the installed chamber

base or chamber ring. Otherwise, no further chamber rings can be

inserted.

Wait until the grout has hardened.

Remove the angle irons and shut-oT bladders and clean the

chamber element seal, i.e. remove dirt and mortar residues.

Fit the chamber ring. To do this, pull the chamber element seal

onto the chamber ring in accordance with point 6. Clean the socket of

the fitted chamber ring and coat evenly with lubricant (installation tip:

do not coat the seal with lubricant.). Ensure that there is no dirt on the

socket after being coated with lubricant. Fit the chamber elements

together without tilting and push them together as far as it will go.

Fill the gap between the concrete chamber and chamber ring with

grouting mortar. In case of a larger backfill volume, alternative

flowable filling materials can also be used for filling the cavity.

247

Fit additional chamber rings and the cone in the same way as

steps 14 – 15.

To fill the chamber cone, soil of group G1 or G2, max. grain size 32

mm (stepped soil with fine particles) should be used.

Add back-fill material at a width of 40 cm carefully and in layer

thicknesses of 20 to 40 cm and compact in line with the stipulations

of DIN EN 1610, ATV-DVWK-A 139. Degree of compaction in the area

of roads DPr ≥ 97 %..

The chamber cone is delivered to the site unshortened and must

be shortened on site for the access opening. The dimension for

shortening depends on the installation depth of the chamber structure

and the choice of chamber cover. Maximum shortening dimension 25

cm. Trimming is carried out in line with the rib valleys, which are

spaced at intervals of 1 cm. Deburr the cut edge.

For the calculation of the shortening dimension, see the installation

sketch on page 250.

The backfilling/embedding of the chamber structure is created up

to 5 cm below the top edge of the shortened cone (OKgK) (see

installation sketch on pageSeite 250). The embedding surface must

be level and must not transmit any point loads to the concrete bearing

ring (add fine grit or a mortar layer if necessary).

Fit the cone seal DN 625 flush to the top edge of the shortened cone.

Coat the inside of the concrete bearing ring with suZcient lubricant

and then mount centrically. To ensure that he concrete bearing ring is

evenly mounted, without impairing the prepared fine layer, the use of

screw-in rope loops (accessories) is recommended. The concrete

bearing ring transmits the traZc loads on to the road foundations.

The concrete bearing ring must be seated solidly and evenly- Point

loads should be avoided (see point 20). Direct load contact between

the concrete bearing ring and the chamber cone should also be

avoided. This is ensured by creating approx. 5 cm of overlap between

the chamber cone and the concrete bearing ring (see installation

sketch dimension hU).

248

A vertical interval of approx. 4 cm must be maintained between the

upper edge of the cone and the concrete bearing ring. This ensures

that after any potential settlement of the road structure, the traZc

load is not transmitted directly into the chamber.

Note:

During the road building phase, insert steel cover plate or similar into

the concrete bearing ring in order to cover the chamber.

Point loads between the concrete bearing ring and the cover

should be avoided. To do this, set the cover on a 1 cm thick layer of

levelling mortar. See page 250.

INSTALLATION INSTRUCTIONS AWASCHACHT PP DN 600with concrete bearing ring or telescopic adapter

Prepare the bearing area of the chamber base according to DIN EN

1610. The subsoil must be capable of bearing a load and even. To do

this, construct a min. 10 cm thick bedding layer (e.g. granular

subbase).

Set the chamber base at the relevant height according to the

planning specification, align and position in accordance with the

connecting pipes. Push-fit connection: Apply lubricant to the spigot

end, check that the seals are positioned correctly before fitting and

clean oT any dirt. Push pipe and chamber together up to the stop.

The optional ball joints/articulated sockets can be used to realise

slope changes up to 13 %, alternatively up to 7.5° to left/right. The

values are reduced accordingly with simultaneous slope change and

direction change. With ball joints and jointed sockets, note the flow

direction that is marked by a raised direction arrow.

The alignment of the chamber base should be checked (the slope

of the chamber channel is 0%).

To fit the enclosed seal, first remove any impurities from the

bottom root of the corrugation of the riser pipe and apply lubricant.

Then fit the seal. In the next step, apply lubricant to the plug-in area

of the chamber base and push the riser pipe in as far as it will go.

251

To fill the chamber components, soil of group G1 or G2, max.

particle size 16 mm (graded soil with fine particles) should be used.

Recommendation: Use recycled material.

Add back-fill material at a width of 40 cm (for installation of the

chambers in groundwater min. 60 cm) carefully and in layer thicknes-

ses of 20 to 40 cm and compact in line with the stipulations of DIN EN

1610, ATV-DVWK-A 139. Degree of compaction in the area of roads

DPr ≥ 97 %.

The following chamber structure is dependent on the chamber

cover that has to be used.

Chamber cover cl. D400

The filling of the riser pipe is created up to 37 cm (16 cm for the cover

+ 1 cm mortar joint + 20 cm for concrete bearing ring) below GOK (see

installation sketch page Seite 253). The embedding surface for the BAR

must be level and must not transmit any point loads to the BAR (add

fine grit or a mortar layer if necessary).

If necessary, the riser pipe should be shortened taking into account

the total height of the chamber. Ensure that the cut is made on the

crest of a corrugation whereby the overlap with the BAR must be at

least 7 cm. The riser pipe is permitted to overlap with the BAR by

maximum 13 cm. One complete root of the corrugation must be

available for the seal. The cut surface is to be deburred.

The optional seal for the BAR should be fitted to the outside of the

riser pipe. Fit the concrete bearing ring onto the riser pipe (use

lubricant). This cover transmit traZc loads on to the road foundations.

It is therefore essential to ensure that there is no direct load contact

between the bearing ring and the chamber. The decoupling of the

chamber and concrete bearing ring and their secure position is

ensured via the overlap of both components of at least 7 cm and max.

13 cm. As the riser pipe can only be shortened in 6.5 cm increments,

the usable height of the telescopic BAR 7 – 13 cm and should be

taken into account in the height adjustment of the chamber. Then fit a

standard cover cl. D 400 onto the concrete bearing ring onto a layer

of levelling mortar.

Chamber cover cl. A15 or B125:

The telescope can realise a 30 cm height equalisation. If necessary,

the riser pipe can be shortened taking into account the overall height

of the chamber.

The seal for the telescopic pipe should be mounted on the inside of

the riser pipe between the first and second corrugation. Insert the

telescopic pipe into the chamber pipe (use lubricant). When aligning

the telescope with the top ground level ensure that the telescope

projects min. 14 cm into the riser pipe. The telescope should be put

into place in such a way that the load bearing capacity is adequate for

the particular load situation. Then place cover DN 600 cl. A or B

inside the telescope.
