Building foundation pit retaining structure
The invention discloses a building foundation pit soil retaining structure, and relates to the technical field of building foundation pit construction. The device comprises a hollow sliding rail, inverted-L-shaped abutting piles are symmetrically and slidably connected to the interior of the hollow sliding rail, a plurality of steel plates are evenly arranged on the two sides of each inverted-L-shaped abutting pile, and a stretching assembly is installed in the hollow sliding rail. According to the construction method, firstly, the two inverted-L-shaped abutting piles are driven by the rotating stretching assembly to drive the steel plate to move away from each other in the length direction of the hollow sliding rail, and the inverted-L-shaped abutting piles are matched with the steel plate to form abutting supporting on the inner wall of the foundation pit; the bottom end of a driving lock rod is conveniently inserted into a lock hole, so that fixed clamping connection of a hollow sliding rail and an inverted-L-shaped abutting pile is completed, abutting supporting on the inner side of a foundation pit is achieved through cooperative use of the inverted-L-shaped abutting pile and a steel plate, and occupation of a triangular supporting area formed by a short pile and an inclined strut on the inner space of the foundation pit is effectively reduced; and the internal operation efficiency of the foundation pit is improved.
本申请公开了一种建筑基坑挡土结构，涉及建筑基坑施工技术领域。本申请包括空心滑轨，空心滑轨的内部对称滑动连接有倒L型抵桩，倒L型抵桩的两侧均匀设置有多个钢板，空心滑轨的内部安装有伸展组件。本申请首先通过转动伸展组件驱动两个倒L型抵桩带动钢板沿着空心滑轨的长度方向做相互远离的运动，并使得倒L型抵桩配合钢板对基坑的内壁形成抵触支撑，同时通过设置自锁组件与锁杆的配合使用，便于驱动锁杆的底端插入锁孔的内部，从而完成对空心滑轨与倒L型抵桩的固定卡接，以此通过设置倒L型抵桩与钢板的配合使用实现对基坑内侧的抵触支撑，有效减少了短桩与斜撑形成的三角支撑区域对基坑内部空间的占用，提高了基坑内部作业的效率。
