UNDERGROUND CONSTRUCTION METHOD AND EARTH RETAINING STRUCTURE
PROBLEM TO BE SOLVED: To provide an underground construction method capable of reducing time and cost while suppressing displacement of an earth retaining wall, and an earth retaining structure.SOLUTION: An earth retaining wall 11, which has a cross-section assuming an uneven shape, is configured by tying up a plurality of sheet piles 11a and 11b together. A reinforcement column 20 is arranged within each vertical groove S1 (recess part) on the excavation area S0 side of the earth retaining wall 11. The reinforcement column 20 is subjected to concrete placing after arrangement of a reinforcement comprising a plurality of main reinforcements and a plurality of annular shear reinforcements surrounding the main reinforcements.SELECTED DRAWING: Figure 1
【課題】山留め壁の変位を抑制しながら、時間及びコストを低減することができる地下工法及び山留め構造を提供する。【解決手段】山留め壁１１は、断面が凹凸形状をしており、複数のシートパイル１１ａ，１１ｂを繋ぎ合わせて構成されている。山留め壁１１の掘削領域Ｓ０側の各縦溝Ｓ１（凹部部分）内に、補強柱２０を配置する。補強柱２０は、複数の主筋と、主筋を囲む環状の複数のせん断補強筋とから構成されている鉄筋を配置した後、コンクリートを打設する。【選択図】図１
