Composite supporting system foundation pit excavation method
The invention discloses a composite supporting system foundation pit excavation method. The method comprises the following steps that excavation blocks are divided; a first side area construction step: firstly excavating the area, far away from the subway, of the first side area, alternately completing concrete support operation, and then completing excavation of the area, adjacent to the subway, of the first side area and concrete purlin and concrete support operation in a limited time; a second side area construction step: after the earth excavation of the first side area is finished, constructing the second side area; in the first middle area construction stage, excavation is conducted after concrete supports of the first side area are formed in middle area construction; in the middle area construction process, excavation operation of the middle area far away from the subway side area is conducted firstly, and pre-assembly operation of steel enclosing purlins and steel supports of the middle area far away from the subway side area is conducted in advance; in the second construction stage of the middle area, excavation and steel purlin and steel support operation are conducted on the side area, adjacent to the subway, of the middle area. The foundation pit can be effectively supported in the construction process as soon as possible, so that the anti-deformation protection requirement of a subway adjacent to the foundation pit is met.
本申请公开了一种复合支撑体系基坑开挖方法，包括如下步骤：开挖区块划分；第一侧区施工步骤，先开挖第一侧区的远地铁侧的区域，并穿插完成砼支撑作业，再限时完成第一侧区的邻地铁侧区域的开挖和砼围檩及砼支撑作业；第二侧区施工步骤，待第一侧区土方开挖结束后，进行第二侧区的施工；中间区施工阶段一，中间区施工待第一侧区的砼支撑形成后开挖；中间区施工过程中，先进行中间区远地铁侧区域的开挖作业，并提前各中间区远地铁侧区域的钢围檩和钢支撑预拼装作业；中间区施工阶段二，进行中间区的邻地铁侧区域的开挖和钢围檩及钢支撑作业。本申请能够尽快在施工过程中对基坑进行有效的支撑，以满足紧邻基坑的地铁的抗变形保护需求。
