Emergency combined reinforcing construction method and reinforcing system structure for retaining wall
The invention discloses a retaining wall emergency combined reinforcing construction method and a reinforcing system structure, prefabricated lattice beams and pre-stressed anchor rods are arranged outside an existing retaining wall, preliminary anchoring is carried out when each section of prefabricated lattice beam is installed, a plurality of prefabricated lattice beams are spliced and installed in one area, and post-cast strip construction is carried out after preliminary anchoring. Anchoring again after the post-cast strip construction is completed; one end of the pre-stressed anchor rod is anchored on the surface of the prefabricated lattice beam outside the existing retaining wall, and the other end of the pre-stressed anchor rod is implanted into underground stable rock soil on the inner side of the existing retaining wall; and deep-layer water guide hole construction is conducted on the existing drainage holes in the existing retaining wall, and the deep-layer water guide holes extend into the underground stable rock soil. The emergency combined reinforcing construction method for the retaining wall has the advantages that the construction period is shortened, the construction risk is reduced, standardized production is achieved, the product quality is guaranteed, construction disturbance is small, emergency rescue reinforcing is achieved, and the construction steps are optimized.
本发明公开一种挡土墙应急联合加固施工方法及加固体系结构，在既有挡土墙外布置预制格构梁和预应力锚杆，每安装一节所述预制格构梁均进行初步锚定，一个区域内拼接安装多个所述预制格构梁并初步锚定后进行后浇带施工，后浇带施工完成后再次进行锚固；所述预应力锚杆的一端锚固于既有挡土墙外的所述预制格构梁表面、另一端植入既有挡土墙内侧的地下稳定岩土内；在所述既有挡土墙上的既有排水孔处进行深层导水孔施工，所述深层导水孔延伸至所述地下稳定岩土内。本挡土墙应急联合加固施工方法具有缩短施工周期，降低施工风险，实现规范化生产，保证产品质量，施工扰动小，应急抢险加固和优化施工步骤的特点。
