Retaining wall reinforcing structure for local collapse and construction method thereof
The invention discloses a retaining wall reinforcing structure for local collapse and a construction method of the retaining wall reinforcing structure, and belongs to the technical field of slope protection or retaining wall supporting. The retaining wall reinforcing structure comprises a retaining wall structure and a reinforcing structure, wherein the retaining wall structure is composed of an undamaged retaining wall and a newly-built retaining wall built on the undamaged retaining wall, and the reinforcing structure is composed of manual hole digging piles, inter-pile connecting beams and inter-soil grouting piles, wherein the manual hole digging piles, the inter-pile connecting beams and the inter-soil grouting piles are arranged in damaged soil behind the retaining wall. The manual hole digging piles and the inter-pile connection beams jointly form a space pile-connection beam structure, and the inter-soil body grouting piles and the pile-connection beam structure form a more stable structural system; the undamaged retaining wall and the newly-built retaining wall are fixedly connected through embedded steel bars and adhesion agents. By the adoption of the connecting structure of the new retaining wall and the old retaining wall and the space pile-connecting beam structure formed by the manual hole digging piles and the inter-pile connecting beams, the undamaged retaining wall can be fully utilized in the reinforcing structure, compared with a conventional reinforcing method, the stability of the reinforcing structure is improved, and the reinforcing construction process is simplified.
本发明公开了一种用于局部坍塌的挡土墙加固结构及其施工方法，属于边坡防护或挡土墙支护技术领域；挡土墙加固结构包括由未破坏挡墙和砌筑在未破坏挡墙上的新砌挡墙组成的挡墙结构，以及由设置在挡土墙后已破坏土体内的人工挖孔桩、桩间联系梁和土体间注浆桩组成的加固结构；人工挖孔桩和桩间联系梁之间共同构成空间桩‑联系梁结构，土体间注浆桩与桩‑联系梁结构形成更为稳定的结构体系；未破坏挡墙和新砌挡墙之间通过植筋和界面剂固定连接。本发明采用新旧挡土墙的连接结构，以及人工挖孔桩与桩间联系梁形成的空间桩‑联系梁结构，能够将未破坏挡墙充分利用到加固结构中，与常规加固方法相比提高了加固结构的稳定性，还简化了加固施工的过程。
