Earth retaining structure utilizing in-situ soil and earth retaining structure construction Method

摘要

The present invention relates to a first panel having a plurality of first perforation holes formed in a predetermined depth in a direction perpendicular to a target ground and formed with a steel sheet pile having a concavo-convex shape in cross section, A second panel formed of a steel sheet pile having a concavo-convex shape in cross section and having a plurality of second perforation holes corresponding to the positions of the first perforation holes and having a first perforation hole and a second perforation hole, And a connector for connecting the first panel and the second panel to each other. Therefore, it can be applied to various grounds such as sandy soil and clay, including the ground where the groundwater is developed, and since it does not require any additional measures, it is applicable to a wide range of applications and the stability of the surrounding ground by excavation can be maintained, It is possible to secure a wider working space compared with the conventional one using a pair of braces and an anchor, so that workability can be improved.
