Construction method for changing support of common component of underground adjacent enclosure structures
The invention relates to the technical field of underground station ventilation pavilion structure construction, and provides an underground adjacent enclosure structure common component support changing construction method which comprises the following steps that S1, a station main body structure is poured and constructed in a main body foundation pit, and an upturning beam is poured at the top of the station main body structure; s2, concrete straight support pouring construction is conducted on the upper portion of the auxiliary foundation pit; s3, an auxiliary foundation pit soil body is excavated to the position below the shared top beam; part of the shared fender posts below the shared top beam are dismantled, and steel corbels are installed on the upturning beam close to the dismantling part to support the shared top beam; s4, the auxiliary foundation pit is excavated while common fender posts at the joint of the auxiliary ventilation pavilion structure and the station main body structure are broken till the auxiliary foundation pit is excavated to the designed standard depth; and S5, pouring construction of the auxiliary ventilation pavilion structure is conducted. The station has the effect of improving the structural integrity between the station main body and the auxiliary ventilation pavilion structure.
本申请涉及地下车站风亭结构施工的技术领域，提出了一种地下相邻围护结构共用构件换撑施工方法，包括以下步骤：S1：在主体基坑内浇筑施工车站主体结构并在车站主体结构顶部浇筑上翻梁；S2：附属基坑上方混凝土直撑浇筑施工；S3：开挖附属基坑土体至共用冠梁下方；拆除共用冠梁下方的部分共用围护桩，在靠近拆除部位的上翻梁上安装钢牛腿以支撑共用冠梁；S4：附属基坑一边开挖一边破除附属风亭结构与车站主体结构连接处的共用围护桩，直至附属基坑开挖至设计标深；S5：附属风亭结构浇筑施工。本申请具有提升车站主体与附属风亭结构之间结构一体性的效果。
