Document Type and Number:
WIPO Patent Application WO/2016/194265
Kind Code:
A1
Abstract:
[Problem] To provide a method by which the number of insertion pipes to be installed can be reduced, the time required for removal of earth-retaining members can be shortened, and construction costs can be reduced. [Solution] Provided is a method that comprises: a step for configuring five or more connected earth-retaining members as one block, inserting an injection pipe adjacent to or near the earth-retaining member positioned at the center of the block, and installing the injection pipe in the ground without fixing the injection pipe to the earth-retaining member; and a step for discharging an injection material from the injection pipe each time an earth-retaining member within the block is pulled up to a fixed height one-by-one so that the injection material flows into a space generated in the ground and fills the space.
