Construction method for excavation and backbuilding of adjacent foundation pits
The invention relates to a construction method for excavation and backbuilding of adjacent foundation pits, and belongs to the technical field of building engineering construction. The construction method comprises seven construction steps. The method is technically characterized in that when one of the two adjacent foundation pits is excavated, the other foundation pit is also excavated in a staggered mode, and compared with the mode that the original foundation pit is excavated after back building, the construction time is greatly shortened. Before the supports are dismantled, the horizontal supporting force close to the foundation pits is increased by arranging the inclined throwing supports, back building and excavation of the foundation pits on the two sides can be conducted at the same time, the construction risk is reduced, and the construction progress of the foundation pits is accelerated.
本发明涉及一种相邻基坑开挖及回筑的施工方法，属于建筑工程施工技术领域。它包括7个施工步骤。本发明的技术要点在于相邻两个基坑中的一个基坑开挖的同时，另一基坑也紧接相错开挖，相较待原基坑回筑后再开挖，施工时间大大缩短。在支撑拆除前，通过设置斜抛撑来增加临近基坑的水平支撑力，两侧基坑的回筑和开挖得以同时施工，不仅降低了施工风险，也加快了基坑的施工进度。
