CONSTRUCTION METHOD OF EARTH RETAINING CONCRETE WALL, EARTH RETAINING CONCRETE WALL, AND SHAFT GUIDE DEVICE
To provide a construction method of an earth retaining concrete wall capable of easily constructing a retaining wall regardless of geologic features and without requiring deep drilling.SOLUTION: A construction method of an earth retaining concrete wall constructing the earth retaining concrete wall formed with H-shaped steels 40, 40 placed opposite to each other in the ground and concrete walls installed in each spaces between these H-shaped steels 40, 40 comprises: an H-shaped steel burying process S1 burying the H-shaped steels 40, 40; first drilling processes S2, S4 drilling first and second holes in a way those are arranged adjacent to one surface and the other opposite surface of the H-shaped steels 40, 40, respectively; a second drilling hole S6 drilling an intermediate hole in communication with the first and second holes at the middle of the first and the second holes; and solidification agent injection processes S3, S5, S7 injecting cement-based solidification in each of the holes after the first, the second, and the third drilling processes.SELECTED DRAWING: Figure 4
【課題】敷地の地質に関係なく、また深堀りすることなく山留め壁を容易に形成することができる山留用コンクリート壁形成方法を提供する。【解決手段】地中に対向配置されたＨ型鋼４０，４０とこれらの各Ｈ型鋼４０，４間に設けられたコンクリート壁とで形成される山留用コンクリート壁を形成する山留用コンクリート壁形成方法であり、Ｈ型鋼４０，４を埋め込むＨ型鋼埋め込み工程Ｓ１と、Ｈ型鋼４０，４の一方および他方の対向する面のそれぞれに近接させて第１、第２の孔を掘る第１の掘削工程Ｓ２、Ｓ４と、第１、第２の孔の中間で第１、第２の孔に連なる中間孔を掘る第２の掘削工程Ｓ６と、第１、第２、第３の掘削工程後にそれぞれの孔にセメント系固化剤を注入する固化剤注入工程Ｓ３、Ｓ５、Ｓ７と、を備えて構成されている。【選択図】図４
