Adjacent foundation pit cooperative construction retaining structure and construction method thereof
The invention provides an adjacent foundation pit cooperative construction retaining structure and a construction method thereof, and belongs to the technical field of foundation pit construction. Theadjacent foundation pit cooperative construction retaining structure comprises adjacent foundation pits, a first supporting structure, a first anchor cable structure, a second supporting structure, asecond anchor cable structure, a top beam structure and a pile anchor structure, wherein a cross anchor passes through a rock containing layer, and the two ends of the cross anchor are pressed against the outer walls of the first supporting structure and the second supporting structure respectively to form a pile-anchor composite structure, which can provide supporting conditions for the subsequent construction of the adjacent foundation pits. Moreover, the top beam structure is connected with the first supporting structure and the second supporting structure integrally, and the pile-anchor composite structure can reduce foundation pit deformation, improve the stability of the rock containing layer and provide support for the adjacent foundation pits, in order that extra support structures are not required in the first foundation pit and the second foundation pit. The first foundation pit and the second foundation pit are smooth, so that the construction operation of the adjacent foundation pits can be synchronized with large-sized machinery.
本申请提供了一种邻接基坑协同施工围护结构及其施工方法，属于基坑施工技术领域。该邻接基坑协同施工围护结构包括邻接基坑、第一支护结构、第一锚索结构、第二支护结构、第二锚索结构、冠梁结构以及桩锚结构。对拉锚杆贯穿夹岩层且对拉锚杆的两端分别与夹岩层相邻的第一支护结构和第二支护结构的外壁抵持，形成桩锚复合结构，可以为邻接基坑的后续施工提供支护条件。而且，冠梁结构与第一支护结构和第二支护结构连接形成整体，另外，桩锚复合结构可以减少基坑变形，提高夹岩层的稳定性，为邻接基坑提供支撑，从而可以使得第一基坑和第二基坑内不需要另行设置支撑结构。第一基坑和第二基坑畅通，使得邻接基坑的施工作业可以大型机械同步自由施工。
