Underground space structure construction method
The invention discloses an underground space structure construction method which comprises the steps that S1, earth excavation is conducted, specifically, excavation of a foundation pit is divided into a two-layer structure, and first-layer supporting and earth excavation are completed; s2, earth excavation and structure construction of a second layer are carried out, and the earth excavation and the structure construction are alternately carried out in the second layer construction; s3, middle supporting column construction; s4, side wall construction; s5, after construction of the side walls and the middle supporting columns is completed, construction of transverse beam plates is conducted; s6, after a box structure is constructed in the second-level underground space, structural construction of the upper underground space, namely the first-level underground space, is conducted synchronously; s7, concrete at the top of the side wall is chiseled away, steel bars are reserved and exposed after chiseling away, the steel bars are in lap joint with the steel bars of the first-level structure, and then concrete is poured to form a continuous underground wall body; and S8, the side wall and the underground space bottom plate are connected through chemical steel bar planting or segmental chiseling of bottom wall body concrete, then the side wall and bottom plate steel bars are anchored, and then concrete is poured to form the underground space bottom plate.
本发明公开了一种地下空间结构施工方法，包括：S1：土方开挖，将基坑开挖分为两层级结构，完成第一层级支护及挖土；S2：进行第二层级的土方开挖和结构施工，第二层级施工采用土方开挖和结构施工穿插进行；S3：中间支撑柱施；S4：边墙施工；S5：边墙和中间支承柱施工完成后，进行横向梁板的施工；S6：当第二层级地下空间施工完成一个箱体结构后，则同步进行上部地下空间即第一层级的结构施工；S7：将边墙顶部混凝土凿除，凿除后保留露出钢筋，此钢筋与第一层级结构钢筋搭接后浇筑混凝土形成连续地下墙体；S8：边墙与地下空间底板的连接采用化学植筋或者分段凿除底部墙体混凝土后与底板钢筋锚固之后浇筑混凝土形成地下空间底板。
