Self-sinking type deep foundation pit retaining wall structure and construction method of underground space structure
An embodiment of the invention discloses a self-sinking type deep foundation pit retaining wall structure. The self-sinking type deep foundation pit retaining wall structure comprises a cylindrical retaining wall body; a ground breaking structure is formed at the bottom of the cylindrical retaining wall body; the cylindrical retaining wall body performs downward ground breakage and sinking throughcooperation of the ground breaking structure and the gravity of the cylindrical retaining wall body; the self-sinking type deep foundation pit retaining wall structure further comprises a water pipe;the water pipe is cast inside the cylindrical retaining wall body and communicates with the outside at the outer side wall of the cylindrical retaining wall body; a water inlet of the water pipe is located on the upper end surface of the cylindrical retaining wall body; and a water outlet of the water pipe is located on the outer side wall of the cylindrical retaining wall body. Through the design, water can be injected through the water pipe to the soil body located on the outer side wall of the cylindrical retaining wall body to soften the soil body in the place, so that the purpose of reducing the frictional resistance of the cylindrical retaining wall body is achieved, and sinking of the cylindrical retaining wall body is facilitated; and thus, reduction of construction procedures canbe realized finally, tamping operations are avoided, construction noises are reduced, the construction period is shortened, and pollution to the surroundings is reduced.
本发明实施例公开的一种自沉式深基坑挡墙结构，包括：筒型挡墙本体，其中，筒型挡墙本体的底部成型有破土结构，筒型挡墙本体通过破土结构与其自身的重力配合实现向下破土和下沉；还包括：浇筑于筒型挡墙本体内，且在筒型挡墙本体的外侧壁处与外部连通的水管，水管的进水口位于筒型挡墙本体的上端面，水管的出水口位于筒型挡墙本体的外侧壁上。通过以上设计，可以通过水管向位于筒型挡墙本体的外侧壁处的土体注水，以软化该处的土体，从而达到减少筒型挡墙本体摩阻力的目的，以利于筒型挡墙本体的下沉；这样最终可以实现施工工序的减少，避免采用夯击操作而减少了施工噪声，缩短工期，且减少对周边环境的污染。
