The invention to a mountain tunnel lining waterproof layer construction device and a mountain tunnel lining waterproof layer construction method, which are used for paving and fixing non-woven geotechnical cloth and a waterproof coiled material on a mountain tunnel construction site conveniently and quickly. The method comprises the following steps: (1) paving the non-woven geotechnical cloth, namely, respectively fixing two rubber guide groove strips to surface of a tunnel wall which is subjected to primary lining along the circumferential direction by using expansion bolts; placing a plurality of roller sliding blocks in each guide groove; binding leading wires at the back of the non-woven geotechnical cloth to the sliding blocks on the two sides; dragging the non-woven geotechnical cloth from the bottom of the arch springing of a tunnel, and moving while binding the leading wires along the circumferential direction of the tunnel until the non-woven geotechnical cloth completely covers the tunnel wall; firmly fixing the non-woven geotechnical cloth to the tunnel wall along the longitudinal direction of the tunnel by using strip-shaped rubber strips and steel bolts, and shearing the leading wires which are bound to the sliding blocks; (2) paving the waterproof coiled material, namely, paving the waterproof coiled material according the same steps, and then fixing the waterproof coiled material to the rubber strips which are used for fixing the non-woven geotechnical cloth by a hot welding method.
Description
technical field [0001] The invention belongs to the technical field of mountain tunnel construction, and in particular relates to a construction device and method for a lining waterproof layer of a mountain tunnel. Background technique [0002] After the tunnel is excavated and the primary lining is applied, non-woven geotextiles and waterproof membranes need to be laid before the secondary lining is poured to prevent water leakage during tunnel operation, reduce the service life of the tunnel and affect driving safety. However, the laying of non-woven geotextiles and waterproof membranes in the current tunnel construction process is completely dependent on manpower, which is time-consuming, laborious and labor-intensive, and the construction efficiency is low. Contents of the invention [0003] The purpose of the present invention is to propose a construction device and method for the lining waterproof layer of mountain tunnels, which helps to lay non-woven geotextiles an...
