The deep foundation pit fender pile structure comprises a fender pile net beam and a top beam, a metal column is inserted into the top beam, and the lower end of the metal column is inserted into the top end of a high-pressure jet grouting pile. The bearing head is arranged on the upper portion of the top beam, one end of the bearing head faces the inner side of the foundation pit, the upper end of the metal column extends into the bearing head, two first-level connectors are arranged on the lower surface of the end, facing the inner side of the foundation pit, of the bearing head, and second-level connectors are arranged at the positions, corresponding to the first-level connectors, of the upper surface of the fender pile net beam. Embedded plates are welded to the first-stage connector and the second-stage connector and located in the corresponding bearing heads or the fender pile net beams. In the application process, the pile guard construction cost for the pile bodies around the foundation pit can be reduced, the construction efficiency is improved, the construction period is shortened, and application and popularization are facilitated.
本发明公开了一种深基坑围护桩结构及施工方法，包括护桩网梁及冠梁，冠梁上插设有金属柱，金属柱的下端插设在高压旋喷桩顶端的内部。承载头设在冠梁上部且一端朝向基坑内侧，且金属柱的上端延伸至承载头内，承载头朝向基坑内侧一端的下表面设有两个一级连接头，护桩网梁上表面且与一级连接头的相对应处设有二级连接头，一级连接头、二级连接头上均焊接有内嵌板，内嵌板位于相对应的承载头或护桩网梁的内部。本发明在应用的过程中，可降低针对基坑四周桩体进行护桩施工的成本，提高施工效率缩短施工周期，有利于进行推广应用。
