Pier Mooring Wharf Construction Technology

Pier Mooring Wharf Construction Technology

Pier mooring is a mooring facility 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.

Outline of Pier Mooring Wharf Construction Technology

Steel pipe piles use machines that strike or vibrate the piles and penetrate deep into the water.At the time of penetration, efficient construction is carried out using a construction support system that utilizes ICT technology.After placing steel pipe piles, the foundation is reinforced with rubble to suppress the displacement of the pile head, and then the floor slab is constructed.For the floor slab, there is a method to assemble the form and directly place the concrete and a method to install the floor slab of the concrete secondary product. As maintaining existing quays is important, we are developing technologies for constructing easy-to-maintain pier type quays and for seismic reinforcement of piers.
