Construction method for accelerating high-span area structure at high-span position and low-span position of basement bottom plate
The invention discloses a construction method for accelerating a high-span area structure at high and low spans of a basement bottom plate. The construction method comprises the following steps: step 1, designing a retaining wall; 2, earthwork slope excavation is carried out; step 3, constructing a bottom plate in a low-span area; 4, constructing a retaining wall; step 5, waterproof construction and profile steel support installation; 6, earthwork backfilling and low-span area outer wall construction are conducted; step 7, bottom plate construction in a high-span area and beam plate construction in a low-span area; 8, high-low cross-region synchronous construction is carried out; the prefabricated retaining wall and the corresponding inclined strut are additionally arranged on the outer side of the outer wall of the low-span area, so that earthwork backfilling can be conducted in advance in the earthwork sloping area at the high-span and low-span joint, operation conditions are provided for construction of the high-span area and a bottom plate, the construction progress of the high-span area is accelerated, the same-layer structure of the high-span area and the low-span area can be constructed synchronously, and the construction efficiency is improved. Various construction problems caused by cross operation are avoided, the retaining wall can be integrated with the low-span area subsequently, and the structural stability is improved.
一种地下室底板高低跨处加快高跨区域结构的施工方法，包括以下步骤：步骤1，挡土墙设计；步骤2，土方放坡开挖；步骤3，低跨区域底板施工；步骤4，挡土墙施工；步骤5，防水施工、型钢支撑安装；步骤6，土方回填、低跨区域外墙施工；步骤7，高跨区域底板施工、低跨区域梁板施工；步骤8，高低跨区域同步施工；本发明通过在低跨区域外墙外侧增设一道预制挡土墙及相应的斜撑，使高低跨交接处土方放坡区域能够提前进行土方回填，为高跨区域及底板的施工提供作业条件，加快高跨区域施工进度，使其与低跨区域同层结构能够同步施工，避免因交叉作业导致的各种施工问题，且挡土墙后续也能与低跨区域形成一体，增加了结构稳定性。
