PURPOSE:To prevent the deterioration of sheathing walls by a method in which plural steel shapes are connected in parallel and erected in a trench, and a sheet is attached in close the face of the inner wall of trench in such a way as to expose it when excavating the inside of the sheathing wall. CONSTITUTION:A flat sheet 16 is attached closely in the face of the inner wall of trench and erected in the trench, and steel shapes 14 connected in parallel are erected into the trench 10 filled with a self-setting stabilizer liquid 12. After the stabilizer liquid 12 is hardened to form a panel, the same panel is formed connectedly in the sideward direction in the same manner to construct a sheathing wall. The inside ground of the sheathing wall is excavated, and the hardened stabilizer 18 inside of the sheet 16 is removed out to expose the sheet 16 and the steel shapes 14. The beautiful sight can thus be kept since the scattering of hardened stabilizer 18 by separation and slackening can be avoided. |
