The invention discloses a prefabricated concrete supporting structure for a subway station foundation pit, the prefabricated concrete supporting structure comprises a middle prefabricated concrete supporting section, and edge prefabricated concrete supporting sections are arranged on the left side and the right side of the middle prefabricated concrete supporting section in an attached mode. Through mutual cooperation of a hand-cranking wheel, a transmission rod, a transmission bevel gear, a driven bevel gear, a threaded rod, a threaded block, an L-shaped rod, a trapezoidal plate, a ball, a movable plate, a square rod, a fourth spring and an inserting rod, after the two positioning blocks are inserted into inner cavities of the adjacent positioning grooves correspondingly, the inserting rod can be driven to move upwards by rotating the hand-cranking wheel, and therefore the inserting rod is inserted into an inner cavity of a groove; the side prefabricated concrete supporting sections and the cast-in-place concrete supporting sections are connected and locked together, so that the middle prefabricated concrete supporting sections and the side prefabricated concrete supporting sections are convenient to disassemble after each time of use, and the purposes of saving materials and protecting the environment are achieved while the disassembly and assembly labor intensity is reduced.
本发明公开了一种地铁站基坑用预制混凝土支撑结构，包括中部预制混凝土支撑段，所述中部预制混凝土支撑段的左右两侧均贴合设有边部预制混凝土支撑段，本发明在使用时，通过手摇轮、传动杆、传动锥形齿轮、从动锥形齿轮、螺纹杆、螺纹块、L形杆、梯形板、圆球、活动板、方杆、第四弹簧和插杆之间的相互配合可在两个定位块分别插入相邻定位槽内腔后，通过转动手摇轮可带动插杆向上移动，从而插入凹槽内腔中，进而将边部预制混凝土支撑段与现浇混凝土支撑段连接锁定在一起，从而便于在每次使用后对中部预制混凝土支撑段和边部预制混凝土支撑段拆卸，降低拆装劳动强度的同时，达到节省材料和保护环境的目的。
