Precast concrete walls

Precast concrete walls

Precast concrete walls are pre-stressed concrete products with a rectangular cross section. Assembling them into walls allows reduced construction schedules in limited land areas without the need to construct large temporary structures, and is an economical construction method.

APPLICATION

APPLICATION

These can be used for road retaining walls and for upgrading city river banks, as well as for the side walls of flood control reservoirs for torrential rain. They can also be used in the foundations of bridge abutments by inserting the tip part into the supporting layers.

CONSTRUCTION

Inner boring method

Inner boring method

Inner boring method using a three-point-supported pile driver has the best track record, and is an economical construction method that allows rapid construction without disturbing the surrounding ground.
Another method is to use a self-propelled pile driver.

Pre-boring method

Pre-boring method

The pre-boring method using a three-point-supported pile driver is able to handle hard soils that are difficult to work with using the inner boring method. On worksites that have large elevation differences, the pre-boring method can be performed using a suspension pile driver. The TRD method (Trench Cutting Re-mixing Deep wall method) can also handle sites with limited vertical space.
