Still further, the corridor outer waterproofing is also laid on the upper surface of the outer waterproofing of the underground structure roof. Still further, the corridor outer waterproofing is laid on the upper surface of the outer waterproofing of the underground structure roof at the top pressure point.
[0011] Furthermore, there are two pressure tops and two overhangs, and the two overhangs are arranged at both ends of the corridor body, and the positions of the pressure tops match the overhangs.
[0012] Furthermore, the corridor body is an arched structure.
[0013] Furthermore, the underground structure top plate body and the pressure top are made of C35 concrete with a waterproof grade of P8.
[0014] Furthermore, the corridor body and the overhang are made of C30 concrete with a waterproof grade of P6.
[0015] The beneficial effects of the utility model are:
[0016] 1. Use the underground structure roof of the subway station as the bottom surface of the corridor structure, maximize the shallow cover depth, and increase the net space of the corridor structure.
