Vertical sliding assembly type foundation pit supporting structure and construction method thereof
The invention provides a vertical sliding assembly type foundation pit supporting structure and a construction method thereof. The vertical sliding assembly type foundation pit supporting structure comprises a steel stand column, a first steel sliding rail and a second steel sliding rail. A plurality of first steel slide rails are uniformly embedded in the underground diaphragm wall. The diaphragm wall reinforcing structure reinforcing steel bar mesh is welded to the diaphragm wall reinforcing steel bar mesh, and the diaphragm wall reinforcing steel bar mesh is arranged on the face, away from the first steel sliding rail, of the diaphragm wall. At least two layers of horizontal steel supporting mechanisms are arranged, each layer of horizontal steel supporting mechanism is connected with the first steel sliding rail and the second steel sliding rail in a clamped mode through a T-shaped connector, and the horizontal steel supporting mechanism on the top layer is replaced by a reinforced concrete support. According to the vertical sliding assembly type foundation pit supporting structure and the construction method thereof, supporting is conducted firstly, then excavation is conducted, one-time supporting is conducted in place, the technical problem that in the construction process of excavation while supporting, layered excavation and layered supporting, deformation of a diaphragm wall and a soil body behind the wall occurs is solved, and the overall stability of the structure is improved.
本发明提供了一种竖向滑移装配式基坑支护结构及其施工方法，包括：钢立柱，立柱上设置第二钢滑轨；若干根第一钢滑轨均匀的嵌设在地连墙上；连续墙加强结构加强钢筋网片焊接在地连墙钢筋网上，地连墙钢筋网设置在地连墙远离第一钢滑轨的一面；水平钢支撑机构，至少两层，每层水平钢支撑机构通过T形接头与第一钢滑轨以及第二钢滑轨卡和连接，其中顶层的水平钢支撑机构被钢筋混凝土支撑替换。本发明的一种竖向滑移装配式基坑支护结构及其施工方法，实现了先支护后开挖，一次性支护到位，避免边开挖边支护、分层开挖、分层支护的施工过程中地连墙和墙后土体的变形的技术问题，提高了结构整体的稳定性。
