DEEP WELL CONSTRUCTION METHOD USING EARTH RETAINING WALL

摘要

PROBLEM TO BE SOLVED: To reasonably construct a deep well together with an earth retaining wall by driving a well construction pipe as a part of an earth retaining wall forming pile while constructing the earth retaining wall, and achieving the excavation of the installation depth of a pump from the lower end of the well construction pipe. SOLUTION: In constructing the earth retaining wall in an open excavation work of an underground structure, the earth retaining wall 1 is constructed by inserting the well construction pipe 10 as a part of the pile in an earth retaining wall forming excavation hole (a pile hole 2) to be excavated to the predetermined depth, the excavation is further achieved from the lower end of the well construction pipe 11 to install the pump 19, and a pumping pipe 18 is arranged on the ground from the pump 19, and the deep well 10 is provided in the earth retaining wall 1.
