Construction method for enlarging external contour of underground structure
The invention relates to the technical field of building construction, in particular to a construction method for enlarging the external contour of an underground structure. A construction method for enlarging the external contour of an underground structure is used for construction of the underground structure comprising at least two layers and comprises the steps that a lower-layer outer wall, a lower-layer top plate and a formwork of a top plate cantilever part are erected at the same time, and then structural construction of the lower-layer outer wall, the lower-layer top plate and the top plate cantilever part is conducted; and then formworks of an upper-layer outer wall, an upper-layer top plate and a top plate cantilever part are erected at the same time, then structural construction of the upper-layer outer wall, the upper-layer top plate and the top plate cantilever part is conducted, and follow-up construction is conducted after a scaffold and the formworks of the cantilever part are dismantled. According to the construction method for enlarging the external contour of the underground structure, the problem that the construction organization difficulty is increased due to the defects that the number of interspersed construction procedures is large and the construction period is long in the underground structure construction process is solved.
本发明涉及建筑施工技术领域，具体涉及一种地下结构外部轮廓变大的施工方法。一种地下结构外部轮廓变大的施工方法，用于对包括至少两层的地下结构的施工，包括：同时搭设下层外墙、下层顶板及顶板悬挑部的模架，然后进行下层外墙、下层顶板及顶板悬挑部的结构施工；再同时搭设上层外墙、上层顶板及顶板悬挑部的模架，然后进行上层外墙、上层顶板及顶板悬挑部的结构施工，拆除脚手架及悬挑部位模架后进行后续施工。本发明解决了地下结构施工中存在着穿插施工工序多、工期长缺陷，使得施工组织难度加大的问题，从而提供一种地下结构外部轮廓变大的施工方法。
