CONTINUOUS WALL USING STEEL PIPE PILES AND CONSTRUCTION METHOD THEREFOR

摘要

To provide a continuous wall using steel pipe piles and a construction method therefor, the continuous wall being composed of the steel pipe piles and installed for the purpose of water cutoff and earth retaining, capable of implementing sufficient water cutoff and earth retaining using a double structure by an elastic member following a displacement even when the displacement is caused between the steel pipe piles depending on water pressure balance.SOLUTION: A continuous wall 1 using steel pipe piles includes an elastic member 3 installed at a position, between a plurality of main piles 2 installed at a predetermined interval, for closing a gap between the main piles 2. The elastic member 3 has a configuration including a hollow member positioned on one side of the continuous wall 1 and a hollow member positioned on the other side, the hollow members connected using a connection member 40. Fluid W is pressurized and injected into the hollow members to enable diameter expanding deformation of the hollow members.SELECTED DRAWING: Figure 5
