Title:
HYDRAULIC END DIE OF TUNNEL SECONDARY LINING TROLLEY AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/184791
Kind Code:
A1
Abstract:
A hydraulic end die of a tunnel secondary lining trolley, comprising a trolley side-die end die assembly (6) and a trolley top-die end die assembly (10). The trolley side-die end die assembly is fixed at an outer ring of a trolley side die assembly (2) by means of a trolley side-die end die fixing device (3); the trolley top-die end die assembly is fixed at an outer ring of a trolley top die assembly (11) by means of a trolley top-die end die fixing device (8); and the trolley side-die end die assembly and the trolley top-die end die assembly are connected to a hydraulic control system by means of a trolley side-die end die hydraulic telescopic device (4) and a trolley top-die end die hydraulic telescopic device (9) respectively. Further disclosed is a construction method for a hydraulic end die of a tunnel secondary lining trolley. The hydraulic end die of the tunnel secondary lining trolley and the construction method therefor may conveniently and quickly install and disassemble the trolley end dies while accelerating the construction progress of the tunnel secondary lining construction, thus reducing construction costs and improving labor productivity.
