摘要

PROBLEM TO BE SOLVED: To provide an underground wall structure enabling extension of a well and a construction method for it. SOLUTION: A soil cement column wall 2 is constructed by filling a column drilled hole formed by a single-shaft or multi-shaft earth auger with soil cement, and erecting a plurality of core materials 3 to be arranged in the lateral direction. Thickness and installation depth of the soil cement column wall 2 and the diameter and installation depth of the core material 1 are predetermined by designing based on the result of hydraulic investigation after the hydraulic investigation made for investigating the geology and hydraulic state such as permeability of the ground by boring the periphery of a drilling scheduled portion 5.
