The unmanned construction is introduced to a disaster

recovery or reconstruction under the following

conditions:

-Workers should be safe from any danger while they are

working;

-The structure of the check dam being constructed

should stand up to debris flow;

- The construction period should be short; and

Enormous volcanic deposits existing around the

construction site should be utilized effectively.

Unmanned Construction

4

Unmanned construction in the hazardous area under the threat of

avalanche of earth and rocks, land slide, or rock falls, and so on.

Hazardous Area

Venous unmanned construction such as

digging, loading and haulage of earth

and rocks Arterial unmanned construction such as

digging, shaping sediment forms, and

haulage, spreading and compacting of

no-slump concrete to build multilayer

sediment control dam

Work Zone Fence for the Work Plan and Supervision◇◇◇◇Operation area of mobile entities is zoned into

compartments such as loading spot, haulage route,

transferring or dumping spot, and compartments of

concrete placement, as considering work

environment such as area, width, curvature, number

of lanes, and densely inhabited district.

◇◇◇◇This system is able to identify mobile entity within

the compartment, records time when entering and

existing the area, and calculate elapsed time within

the area.

◇◇◇◇Supervisor and resident engineers are able to

watch and confirm relevant information on works

performed and current work in progress in the each

compartment.

Based on the work plan, supervisor is able to

issue work order daily to inform gang leaders

and others of work orders and safety instructions.

Based on the work plan, supervisor is able to

issue work order daily to inform gang leaders

and others of work orders and safety instructions.

Work Order

Supervisor is able to communicate all at once

to take shelter by informing emergency alert

as to earthquake, tsunami and localized torrential downpour.

Here, supervisor can choose one of pre-arranged

alarm categories and also entry her/his order.

REMARKS

With the objective of increasing construction

safety and efficiency on daily duty-cycle.

This system

-Gives a detailed visibility into appearances

and motions in the unmanned construction,

and

- Enables the decision-makers to take quick

actions.
