[0002] The anti-leakage construction of tunnels is the focus and difficulty of current design and construction. Once water leakage occurs in the tunnel, it will directly affect the quality of the main structure of the project and its safety in use. In the process of highway tunnel construction, the design and construction according to the New Austrian Tunneling Method has been generally adopted. The waterproofing in the tunnel is achieved by laying a waterproof board between the initial support and the secondary lining layer, and laying a buffer layer of non-woven geotextile between the waterproof board and the initial support surface. The waterproof board is hung after the non-woven geotextile is laid. When laying the waterproof board, fix the waterproof board to the predetermined position, and then heat it with a manual electric heat welder to weld the waterproof board to the special hot-melt gasket that fixes the non-woven fabric. Hot-melt gasket

[0003] Multiple rows of hot-melt gaskets are set at intervals along the extension direction of the tunnel. When installing the hot-melt gaskets, their positions are determined by marking lines on the tunnel wall with spray paint, then measuring the specified distance on the line and marking points, and then fixing the hot-melt gaskets at the determined points, repeating the spraying of paint, marking, marking points, and fixing the hot-melt gaskets. However, this method consumes a lot of time and manpower during operation, and the process is cumbersome, which seriously restricts the laying progress of the geotextile waterproof board, and the burrs and dust on the surface of the hot-melt gaskets affect the subsequent hot-melt effect.
