Prefabricated assembled type underground passage interface frame structure and construction method
The invention relates to the technical field of deep underground structure engineering, and particularly relates to a prefabricated assembled type underground passage interface frame structure and a construction method. The prefabricated assembled type underground passage interface frame structure comprises a top plate, a middle plate and a superimposed side wall, wherein the top plate, the middle plate and the superimposed side wall are enclosed to form an underground passage; the superimposed side wall is positioned on the side of the underground passage and is fixedly connected with prefabricated columns; the top plate is positioned on the side of the underground passage and is fixedly connected with a frame beam; the left end and the right end of the frame beam are respectively and fixedly connected with the top ends of the two prefabricated columns; the bottom ends of the prefabricated columns are fixedly connected with the middle plate. In the assembling stage, connection is realized by section steel, and loads in the construction stage are all borne by the section steel; and after assembling is completed, an integral frame is formed by cast-in-place concrete wet nodes; and in the use stage, the integral frame is jointly borne by section steel concrete. The whole interface frame and the side wall are connected into a whole to form a reliable integral stress system. The section steel assembling construction is convenient and rapid, the construction period is greatly shortened, the engineering quality is reliable, and the prefabricated assembled type underground passage interface frame structure is suitable for subways and similar engineering main body structures and has certain social and economic benefits.
本发明涉及深地下结构工程技术领域，为一种预制拼装式地下通道接口框架结构及施工方法，包括顶板、中板及叠合侧墙，顶板、中板及叠合侧墙围合形成地下通道；叠合侧墙位于地下通道侧固定连接有预制柱，顶板位于地下通道侧固定连接有框架梁，框架梁的左右两端分别与两个预制柱的顶端固定连接，预制柱的底端与中板固定连接。拼装阶段通过型钢连接，且施工阶段的荷载均有型钢承担，拼装完成后通过现浇混凝土湿节点形成整体框架，使用阶段由型钢混凝土共同承载。整个接口框架与侧墙连成整体，形成可靠的整体受力体系。型钢拼装施工便捷，大大缩短了施工周期，工程质量可靠，适用于地铁及类似工程主体结构，具有一定的社会经济效益。
