Self-sinking type deep foundation pit barrier wall structure and construction method for underground space structure
The invention provides a self-sinking type deep foundation pit barrier wall structure. The self-sinking type deep foundation pit barrier wall structure comprises a barrel type barrier wall body, wherein the bottom of the barrel type barrier wall body is provided with a ground breaking structure, and the ground breaking structure and the barrel type barrier wall body are in gravity matching to achieve downward ground breaking. The self-sinking type deep foundation pit barrier wall structure further comprises resistance enhancement devices, wherein the resistance enhancement devices are arrangedon the outer side wall of the barrel type barrier wall body and used for cooperating with a foundation to adjust the upward resistance applied by the foundation to the barrel type barrier wall body.The bottom of the barrel type barrier wall body is provided with the ground breaking structure, hammering operation is avoided, self-sinking can be achieved, and construction procedures are decreased;generated construction noise is low, the construction duration is short, and pollution to the surrounding environment is small; and the resistance enhancement devices are arranged to adjust the upward resistance applied by the foundation to the barrel type barrier wall body, and thus, the sinking speed and/or perpendicularity of the self-sinking type deep foundation pit barrier wall structure canbe controlled according to different soil body conditions. The invention further provides a construction method for an underground space.
本发明提供了一种自沉式深基坑挡墙结构，包括：筒型挡墙本体，其中，所述筒型挡墙本体的底部成型有破土结构，所述破土结构与所述筒型挡墙本体的重力配合实现向下破土；还包括设置上所述筒型挡墙本体的外侧壁上的增阻装置，用于与地基配合，调节所述地基对所述筒型挡墙本体向上的阻力。通过在所述筒型挡墙本体的底部成型所述破土结构可以无需进行锤击操作，即可实现自沉，使得施工工序较少，产生施工噪声较小，工期较短，对周边环境带来的污染较小；设置增阻装置，用于调节所述地基对所述筒型挡墙本体向上的阻力，从而可以根据不同的土体条件来控制自沉式深基坑挡墙结构下沉的速度和/或垂直度。本发明还提供了一种地下空间的施工方法。
