A method of Safety Maintenance only with Soil sheating work

摘要

According to the present invention, a method for securing safety with only a soil sheathing wall in a section in which a support is dismantled comprises the following steps of excavating the ground, decompressing a portion of a pre-compression load, and dismantling a support having a lower portion to be dismantled. Therefore, construction costs and a construction period can be reduced, and further, stability of a soil sheathing wall and a surrounding structure can be maintained.
