Waterproof board installation trolley for tunnel

Abstract

The invention discloses a waterproof board installation trolley for a tunnel and belongs to the technical field of tunnel construction. The waterproof board installation trolley comprises a main body rack and a walking mechanism. Arc-shaped crawling rails are installed at the two ends of the main body rack correspondingly. The walking mechanism is installed at the bottom of the main body rack. The waterproof board installation trolley further comprises a winding and unwinding mechanism, a jacking mechanism and a locating mechanism. The jacking mechanism is fixedly connected with the main body rack and used for jacking a completely unwound waterproof board or bound rebars in place. The locating mechanism is connected to the lower end of the main body rack. The locating mechanism places the coiled waterproof board through a drawer type structure and is used for making the waterproof board be located and providing support for winding and unwinding of the waterproof board. The winding and unwinding mechanism comprises a drum, a clamping structure and a crawling structure. The drum is assembled in a subsection mode. According to the waterproof board installation trolley, overall jacking, fast function conversion and rail type walking are achieved, the height of the main body rack can be adjusted, and laying of the wide waterproof board and jacking of the rebars can be conducted.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a trolley for installing a waterproof board for a tunnel. Background technique [0002] Most tunnel waterproofing and drainage in my country adopts composite support and lining structure, and the laying of waterproof board between the primary support and the secondary lining is the core and key of tunnel waterproof technology. The construction quality of the waterproof board has a great influence on the overall waterproof effect of the tunnel. important. At present, my country's waterproof board laying equipment generally includes the following two situations: [0003] (1) Most of them use simple welding benches and lay them manually, which has problems such as low construction efficiency, high labor intensity, poor laying quality, and low safety. [0004] (2) In view of the shortage of simple welding benches, domestic waterproof board laying equipment ha...

Problems solved by technology

[0006] (1) Most of the existing waterproof board trolleys are laid for the commonly used 4-meter-wide waterproof boards, but there are few trolleys for laying wide-width waterproof boards with a width of 7 meters;

[0007] (2) Most of the existing waterproof board laying trolleys are only used for laying waterproof boards for a single construction operation, with relatively single functions and low equipment versatility;

[0008] (3) The existing waterproof boa
