Deep foundation pit double-T-shaped underground diaphragm wall adjacent to subway viaduct and deep foundation pit construction method
The invention discloses a deep foundation pit double-T-shaped underground diaphragm wall adjacent to a subway viaduct and a deep foundation pit construction method.The deep foundation pit double-T-shaped underground diaphragm wall comprises a plurality of underground diaphragm wall units continuously arranged in the circumferential direction of a foundation pit, and each underground diaphragm wall unit comprises an outer wall plate and a plurality of T-shaped connecting pieces, the adjacent end is connected to the adjacent end of the external wall panel of the adjacent diaphragm wall unit; the inner wall plate and the outer wall plate are oppositely arranged, and the length of the inner wall plate is smaller than that of the outer wall plate; the supporting wall plate is arranged between the outer wall plate and the inner wall plate, and the two ends of the supporting wall plate are connected to the outer wall plate and the inner wall plate in a supporting mode respectively. The problem that the structural safety of the existing subway viaduct is affected due to the fact that a traditional underground diaphragm wall is adopted for construction of the foundation pit adjacent to the existing subway viaduct and horizontal displacement is prone to being generated is solved.
本发明公开了一种邻地铁高架的深基坑双T形地下连续墙及深基坑施工方法，包括沿基坑的周向方向连续设置的多幅地连墙单元，所述地连墙单元包括：外墙板，所述外墙板具有相对的两邻接端，所述邻接端连接于相邻地连墙单元的外墙板的邻接端；内墙板，所述内墙板与所述外墙板相对设置，所述内墙板的长度小于所述外墙板的长度；支撑墙板，设置于所述外墙板和所述内墙板之间，所述支撑墙板的两端分别支撑连接于所述外墙板和所述内墙板。本发明解决了在紧邻既有地铁高架的基坑施工采用传统的地连墙，容易产生水平位移而影响既有地铁高架的结构安全的问题。
