PURPOSE:To raise the strength of an underground wall against the pressure of soil as well as to enhance its water shielding property by a method in which plural first pipes with guiding parts are erected and a wall body with the second pipe is erected on both sides of steel plates in a pit for the underground wall under the guidance of the first pipes. CONSTITUTION:Plural pits 3a for constructing an underground wall are excavated, the first steel pipe 1 with the first guiding part 1a is erected in the pit 3, and then under the guidance of the first pipe 1, a pit 3b for constructing the underground wall is excavated while pouring a fluid for preventing the degradation of the wall into the space between the first pipes 1. Then, under the condition that the second guiding parts 2a provided on both sides of a main wall-constituting body 2 in which the second steel pipe 2b is welded to both sides of a steel plate 2c is fitted with said first guiding part 1a, the main wall- constituting body 2 is penetrated into the pit 3a under the guidance of the pipe 1 and then concrete is placed to replace the fluid. Thus, an underground wall is constructed. |
