TBM : METHOD OF CONSTRCUTION

CRANE –TO ASSEMBLY THE

TBM

Component of TBM

This method starts by excavating a trench to provide a space for assembly the TBM components. The trench is reinforced with

diaphragm walls and steel struts.

Trench

The TBM components is placing down into the trench using a crane

TBM work under the flyover

Tunnel track under the flyover

Tunnel segment installation

During the drilling process, the assemble of components is doing at the same time.

Segment installation

While the drilling works are carried out near the building, surveys will be conducted to monitor for any settlement that

may occur in any nearest buildings during the work.

TBM work

Survey work

At the end of the point, the trench will be excavate similar with the start point as a receiver trench for the TBM. Upon arrival, the TBM is

then dismantled and brought upon to the surface

Lastly, the tunnel is done when all the appliances is completely installed.

PROBLEM DURING TUNNELING WORK

PROBLEM :

Noise & vibration nearest building

EFFECT :

Disruption to nearest premise

SOLUTION :

Strictly control the

noise & vibration

PROBLEM :

Geotechnical environment

1

2EFFECT :

Drilling different type of soil

(from hard rock to soft soil)

SOLUTION :

Using slurry types of TBM
