Construction method of support changing structure
The invention discloses a construction method of a support changing structure, which comprises the following steps: S1, calculating the position and stress of a steel pipe column based on the support requirement of a foundation pit and the requirement of a building to be constructed; s2, supporting pile construction at the edge of the foundation pit is completed based on the foundation pit supporting requirement, and steel pipe column construction is completed at the preset position based on the calculation result of S1; s3, after construction of the supporting piles and the steel pipe columns is completed, soil is taken downwards, and after soil is taken to the preset depth, a first layer of steel pipe supports are installed; s4, downward construction continues, and steel pipe support construction is conducted layer by layer till foundation pit excavation is completed; and S5, after foundation pit excavation is completed, force transmission belt construction is conducted, and then basement cushion layer construction, waterproof construction and bottom plate structure construction are conducted in sequence according to design requirements. According to the method, foundation pit supporting design and building structure design are combined, it is ensured that the steel pipe column can serve as a steel pipe supporting stress point and can also serve as a permanent structural member for supporting structure construction, the steel pipe column is constructed in advance, permanent and temporary combination is achieved, and cost is saved.
本发明公开了一种支护换撑结构的施工方法，包括：S1：基于基坑支护需求及待施工建筑需求，完成钢管柱位置及受力计算；S2：基于基坑支护需求完成基坑边缘处支护桩施工，并基于S1的计算结果，于预设位置完成钢管柱施工；S3：在支护桩及钢管柱施工完成后，向下取土，取土至预设深度后，安装第一层钢管支撑；S4：继续向下施工，逐层进行钢管支撑施工，直至基坑开挖完成；S5：基坑开挖完成后，进行传力带施工，然后按设计要求依次进行地下室垫层、防水及底板结构施工。本发明方法将基坑支护设计及建筑结构设计相结合，确保钢管柱既能作为钢管支撑受力点，又能作为永久结构构件支撑结构施工，提前施工钢管柱，永临结合，节约成本。
