Prestressed system fabricated underground structure and construction method thereof
The invention discloses a prestressed system fabricated underground structure and a construction method thereof. The prestressed system fabricated underground structure comprises an underground enclosure structure and a fabricated underground main body structure, the underground enclosure structure comprises a temporary supporting component used for supporting an underground diaphragm wall, and the fabricated underground main body structure comprises an annular component formed by connecting prestressed steel beams; and a support changing block is arranged between the annular component and the underground diaphragm wall, and is used for supporting the underground diaphragm wall through the annular component so as to remove the temporary supporting component. According to the prestressed system fabricated underground structure, an innovative vertical support changing system is adopted to solve the conflict problem of assembly and lowering of assembly parts and support in a foundation pit, a main body structure is firstly looped and then is debraced, the looped main body structure can effectively form a rigid hinge, the overall stability and safety of the foundation pit are enhanced, the total section of a component joint is pressed through prestress, bending moment and shearing force can be effectively transmitted, joint sealing and waterproofness are ensured, the integrity is good, and safety and reliability are achieved.
本发明公开了一种预应力体系装配式地下结构及施工方法，包括地下围护结构和装配式地下主体结构，地下围护结构包括用于支撑地下连续墙的临时支撑构件，装配式地下主体结构包括通过预应力钢束连接形成的环状构件，该环状构件与地下连续墙之间设有换撑块，换撑块用于该环状构件支撑地下连续墙以拆除所述临时支撑构件。本发明采用创新的垂直换撑体系解决了装配件拼装、下放与基坑内支撑冲突问题，主体结构先成环后拆撑，成环的主体结构能有效形成刚性铰，增强基坑整体稳定性和安全，预应力使构件接缝全截面受压，能有效传递弯矩、剪力，保证接缝密封、防水，整体性好，安全可靠。
