Kind Code:
B2
Abstract:
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
