Underground building construction method
The invention belongs to the technical field of underground space development, and discloses an underground building construction method which comprises the steps that S1, an underground foundation pit is excavated through excavating equipment, a top plate is constructed on the construction ground surface, and the top plate covers an opening of the foundation pit; s2, a supporting cross beam is lowered into the foundation pit, the supporting cross beam is fixed to the designed elevation position of an underground N-layer floor slab needing to be constructed, and excavation continues to be conducted on the lower portion of the supporting cross beam through excavation equipment; s3, a formwork assembly is erected on the basis of the supporting cross beams, and concrete is poured into the formwork assembly to form a current floor slab; s4, after the current floor slab reaches the maintenance time, the formwork assembly is dismantled; s5, a supporting cross beam is lowered, the supporting cross beam is fixed to the designed elevation position of an underground (N + 1)-layer floor, and excavation continues to be conducted on the lower portion of the excavation equipment; and S6, the step S3 and the step S4 are repeated to complete construction of the underground (N + 1) floor slabs. According to the construction method, the pouring construction procedure of the floor and the excavation procedure of the lower space can be synchronously carried out, and the construction period is effectively shortened.
本发明属于地下空间开发技术领域，公开一种地下建筑施工方法，包括：S1、使用挖掘设备开挖地下基坑，并在施工地表施工顶板，顶板覆盖基坑的开口；S2、下放支撑横梁至基坑内，并将支撑横梁固定于所要施工的地下N层楼板的设计标高位置，挖掘设备于下方继续开挖；S3、基于支撑横梁支设模板组件，并于模板组件内浇筑混凝土，以形成当前楼板；S4、待当前楼板达到养护时间后，拆除模板组件；S5、下放支撑横梁，并将支撑横梁固定于地下N+1层楼板的设计标高位置，挖掘设备于下方继续开挖；S6、重复步骤S3和S4，以完成地下N+1层楼板的施工。该施工方法使得楼板的浇筑施工工序与下方空间的开挖工序能够同步进行，有效缩短工期。
