We are the only manufacturer of rotary multi-horizontal cutter diaphragm wall trencher in Japan.

Foundation is constructed into the underground for the purpose to transmit the weight of structures to the bearing layer. Foundation work is classified, based on the method of transmitting sturucture weight, into ① spread foundation ② pile foundation ③ caisson base ④ diaphragm wall foundation. We can provide the equipment securing the safety and improving operating efficiency for diaphragm walling and cast-in-place piling Construction, meeting the requirement from our customers.

① Spread foundation

In case better bearing layer supporting the structures exists at shallow depth, the weight of structure is directly transmitetd to bearing layer through mat foundation or footing foundation.

② Pile foundation

In case better bearing layer supporting the structures exists at deeper depth, the weight of structure is transmitted to deeply located bearing layer through cast-in-place pile by excavating up to bearing layer or penetrating prestressed concrete pile.

③ Caisson base

The weight of structures is transmitted to bearing layer through box shaped reinforced concrete or steel hollow structure which is installed at specified bearing layer by excavating or sinking it.

④ Diaphragm wall foundation

RC (reinforced concrete) diaphragm wall constructed in the underground with the trencher is just used as foundation body of the structure. It is possible to form simple straight wall, rectangular or polygonal shaped closed-crosssection wall.

Diaphragm Wall Construction

Diaphragm wall construction is one of key technologies of civil works and is to construct a continuous wall as foundation or retaining wall when a large scale structure is constructed in the underground.

Rotary multi-horizontal cutter diaphragm wall trencher

Rotary multi-horizontal cutter diaphragm wall trencher is a representative machine utilized for the construction of diaphragm wall and a requirement for strengthening its performance and capability is expected for future large scale projects such as underground railway and highway.

We can offer the equipment with "Only One" features upon customer's request.

Multi-auger type diaphragm walling machine

Multi-auger type diaphragm walling machine is the equipment to form a rectangular soil-mixing column wall by mixing and kneading the soil and cement slurry as excavating with multi-augers. Side wall cutter can remove uncut section remained by auger head excavation and construct a rectangular wall with flat surface. This trencher is utilized based on designing and site conditions due to its better operating performance for shallow retaining wall construction.

We can offer the equipment with "Only One" features upon customer's request.

Cast-in-Place Pile Construction

Cast-in-place pile construction is to drill the ground, install reinforced steel cage in excavated hole, then place ready mixted concrete in order to construct reinforced concrete pile at the site.

Cast-in-Place Piling Machine

For cast-in-place pile construction, various construction methods are selected based on drilling method, pile diameter, pile length, etc. Especially for the work in urban area, the safety secured and smooth work at resctricted space is essential and it is very important to select the proper working method and machine in consideration of environmental affection such as the noise or vibration.
