This technology mechanizes the screeding work done by divers in the water.
This construction method is capable of responding to the earthquake resistance, deterioration, and increasing size of vessels at low cost with a short construction period while the facilities are in service.
This method improves the soft ground from the sea by using a special ship.
This method uses a rotary penetration device and a specially shaped head at the tip of the casing to construct compaction piles on soft ground with no vibration and low noise.
This large-diameter (φ 1600 mm to 2000 mm) deep mixing treating method mixes and stirs slurry solidification material and in-situ soil by relative mixing of the outer and inner blades.
This method uses a special stirrer attached to the tip of a backhoe type machine to mix slurry-like improver with in-situ soil to form a stable improver.
A caisson is a large box made of reinforced concrete. It is used as a breakwater to prevent waves and as a quay to anchor ships.
The submerged tunnel construction method is a technology to construct a tunnel, etc., at the bottom of the sea by immersing a submerged Caisson made of concrete, steel plate, etc., as a dry dock or on land.This method has the advantage of reducing the overall length of the tunnel because it is constructed by connecting artificial islands, etc., and can reduce the overburden of the tunnel.
Dredging removes sediment accumulated in the seabed, the bottom of ports, sea routes, rivers, and lakes.
Pier mooring is a mooring facility that is often used at ports and harbors.It has a light structure with floorboards placed on columns such as steel pipe piles driven into the bottom of the water, making it suitable for locations where the ground is soft.
The CDM (Cement Deep Mixing) method mixes and stirs slurry solidification material and in-situ soil. The amount of soil equivalent to the input amount of solidification material is then discharged and the construction is carried out without affecting the surrounding ground or structures.
