Large-clearance modular lining trolley for tunnel

Abstract

The invention discloses a large-clearance modular lining trolley for a tunnel. The large-clearance modular lining trolley for the tunnel is characterized by comprising a door frame which is modularized, a door frame supporting structure, an adjustable die plate and a die plate supporting system, wherein the door frame of the lining trolley is fixedly connected between two arch-shaped door frames through top longitudinal beams; the adjustable die plate of the lining trolley is divided into a left half die plate and a right half die plate which are symmetrically arranged, and the adjustable die plate of the lining trolley enables random switching among a standard section, a curved widened section and a lower anchoring part section in an adjustable manner; the whole die plate supporting system of the lining trolley can form a large-clearance reversed V-shaped structure. According to the large-clearance modular lining trolley for the tunnel, the modular structure can effectively improve the working efficiency and increase the clearance; the ventilating condition can be improved, so that the construction safety can be improved.

Description

technical field [0001] The present invention relates to the equipment used in the secondary lining process of tunnel construction, more specifically a lining trolley, especially used in the general section and curve widening section, as well as the widening and heightening section of the general anchor section. Lining trolley during secondary lining construction of converted tunnel. Background technique [0002] The lining trolley is a special equipment for the secondary lining in the tunnel construction process. It is used for the concrete lining construction on the inner wall of the tunnel. The lining trolley is an indispensable non-standard product for the secondary lining in the tunnel construction process. The existing technologies mainly include: Simple lining trolley, fully hydraulic automatic walking lining trolley and grid-type lining trolley. However, due to the particularity of the tunnel construction environment, these masonry trolleys have complex structures, c...

AI Technical Summary

Problems solved by technology

However, due to the particularity of the tunnel construction environment, these masonry trolleys have complex structures, cumbersome construction, and are prone to construction errors and defects. The lining trolleys occupy a large area, and the construction in the tunnel is limited. The multi-channel gantry is used as the force-bearing structure, which hinders the air circulation in the tunnel and makes the air circulation in the tunnel poor; due to the large number of gantry, the adjustable range of the door frame and the formwork of the lining trolley connected by a short oil cylinder is small; the traditional lining trolley Without modular design, if the section of the general anchor section is encountered, it is skipped. After the tunnel is penetrated, the lining trolley is withdrawn from the tunnel and converted into a section of the general anchor section, and then moved to the general anchor section for lining concrete pouring. This process greatly reduces work efficiency, prolongs the construction period and increases production costs
