Abstract

The invention provides a coiled material hanging and fixing device, and belongs to the technical field of tunnel construction. The coiled material hanging and fixing device comprises a base, a containing frame and a compression mechanism, wherein the containing frame is arranged on the upper end face of the base and used for placing a waterproof layer coiled material, the compression mechanism isarranged above the base and used for compressing a waterproof layer on a tunnel section outline, the angle and length of the compression mechanism are adjustable, the upper end face of the base is further provided with a lifting mechanism used for driving the compression mechanism to rise and fall, the upper end of the lifting mechanism is fixedly provided with a work platform, and the compressionmechanism is arranged on the upper end face of the work platform. The provided coiled material hanging and fixing device has the advantages that the waterproof layer pulled out of the waterproof layer coiled material winds the compression mechanism, the lifting mechanism rises and falls to drive the compression mechanism on the work platform to rise and fall, the compression mechanism constantlyadjusts the angle and the elongation amount, so that the waterproof layer always compresses on the tunnel section outline through the compression mechanism, it is achieved that the waterproof layer isautomatically laid, and the problems that the labor intensity is large and the working efficiency is low when the waterproof layer is manually hung are solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and more specifically relates to a coil hanging and fixing device. Background technique [0002] Since the 1980s, with the development of water layer membrane technology, the tunnel design has gradually adopted the all-inclusive waterproof technology, that is, laying along the contour of the tunnel section, and setting it between the shotcrete for the primary support and the secondary lining. A layer of plastic waterproof layer to achieve the purpose of preventing groundwater in the formation from seeping into the tunnel. The laying of waterproof layer has become an indispensable waterproof measure for the construction of roads, railways and subway tunnels. [0003] At present, the waterproof layer hanging construction of the tunnel adopts the method of standing on the work trolley and manually lifting the hanging method. The manual operation is labor-intensive and the work efficienc...
