Tunnel secondary lining trolley hydraulic end die and construction method thereof

Abstract

The invention discloses a tunnel secondary lining trolley hydraulic end die and a construction method thereof. The trolley hydraulic end die comprises a trolley side-die end die assembly and a trolleytop-die end die assembly. The trolley side-die end die assembly is fixed to a trolley side-die assembly outer ring through a trolley side-die end die fixing device. The trolley top-die end die assembly is fixed to a trolley top-die assembly outer ring through a trolley top-die end die fixing device. The trolley side-die end die assembly and the trolley top-die end die assembly are connected witha hydraulic control system through a trolley side-die end die hydraulic telescopic device and a trolley top-die end die hydraulic telescopic device correspondingly. Compared with the prior art, the tunnel secondary lining trolley hydraulic end die and the construction method thereof have the positive effects that the key technical problems of tunnel secondary lining trolley construction are updated, assembling and disassembling of a trolley end die can be achieved conveniently and quickly, meanwhile, the work progress of tunnel secondary lining construction is accelerated, the construction cost is reduced, and the labor productivity is increased.

Description

technical field [0001] The invention relates to a hydraulic end form of a tunnel secondary lining trolley and a construction method thereof, which is mainly used for pouring and setting the secondary lining concrete of railway and highway tunnels. Due to the special nature of tunnel construction, the end formwork of the trolley must be installed and dismantled every time it is used, and the operation process cannot be guaranteed to be exactly the same every time, which has a great impact on the subsequent work of tunnel elimination. The invention can reduce the process of installing and dismantling the end mold each time, saving a lot of manpower and material resources, and at the same time, ensure that the position error accuracy of the buried water stop in the circumferential direction is within 5mm, and ensure that the water stop belt will not be folded during the construction process. No damage, so that the quality of tunnel construction can be improved to a new level. B...

Problems solved by technology

[0002] With the continuous increase of the scale of infrastructure construction in our country, the construction of new roads and railways is increasing day by day. The construction of the end formwork of the second lining trolley of the newly added railways and road tunnels used to be the method of adding wooden squares Single-piece assembly construction, this method has many construction procedures, cumbersome operations, low construction efficiency, high construction cost, it is difficult to ensure the quality of the end of the second lining, and seriously affects the overall construction period

At the same time, the installation process of the waterstop buried in the middle of the second lining ring cannot meet the design requirements, the size and position cannot be accurately positioned, and most of them are even damaged
