Construction method for synchronous construction of underground station main body and accessory structure
The invention relates to the technical field of underground building construction, in particular to a construction method for synchronous construction of an underground station main body and an accessory structure, which comprises the following steps: construction design: designing according to a mode of simultaneously excavating a main body structure foundation pit and an accessory structure foundation pit; excavation preparation is conducted, specifically, site hardening, building envelope construction of a main body structure and an accessory structure and precipitation well construction of the main body structure and the accessory structure are conducted; the foundation pits of the main body structure and the accessory structure are excavated and constructed at the same time, deformation of the foundation pits is monitored, and the deformation condition of the foundation pits is monitored synchronously in the process of excavating and constructing the foundation pits of the main body structure and the accessory structure at the same time. Through synchronous construction of the main body and the accessory structure of the underground station, the construction period is greatly shortened, the requirements of projects with high construction period requirements are met, the problem of secondary excavation or secondary support of partial structures of the foundation pit of the main body structure caused by construction of the accessory structure is avoided, and the construction efficiency is improved. And excessive disturbance to the soil body around the building is avoided.
本发明涉及地下建筑施工技术领域，尤其涉及地下车站主体与附属结构同步施工的施工工法，所述施工工法包括以下步骤：施工设计：按照主体结构与附属结构基坑同时开挖的方式进行设计；开挖准备,包括场地硬化、主体结构与附属结构的围护结构施工、主体结构与附属结构的降水井施工；主体结构与附属结构的基坑同时开挖施工，基坑变形监测，在主体结构与附属结构的基坑同时开挖施工过程中，同步监测基坑的变形情况。本发明通过地下车站的主体与附属结构同步施工，大大缩短了施工工期，满足了对工期要求较高的项目的需求，避免出现由于附属结构的施工导致主体结构基坑的部分结构的二次开挖或二次支护问题，进而避免了对建筑周围土体的过分扰动。
