The embodiment of the utility model is realized by the following technical scheme: the utility model provides a mounting structure of waterproof board for tunnel, includes waterproof board body, geotechnological cloth, hot melt liner and passageway, geotechnological cloth is fixed through penetrating the nail and is laid the passageway surface, the waterproof board body orientation geotechnological cloth one side is equipped with the hanging strip, the hot melt liner has the staple, through the staple passes in proper order hanging strip and geotechnological cloth with the passageway is fixed continuous.
Further, the waterproof board body and the geotextile are equally divided into a plurality of parts to wind the inner wall of the channel in a sequentially lap joint manner to form, the area of each geotextile is larger than that of the waterproof board body, and the lap joints of the waterproof board bodies are welded by a hot melting machine.
Further, the hanging strip is provided with a plurality of and evenly spaced distribution is fixed in waterproof board body one side.
Further, the hanging strip is welded on the surface of the waterproof plate body through a hot-drying welding gun.
Further, the hanging strip and the waterproof board body are made of the same material.
Furthermore, the waterproof board body is made of PVC materials.
Furthermore, a layer of reinforced concrete layer is laid on the surface of the waterproof board body.
The technical scheme of the embodiment of the utility model at least has the following advantages and beneficial effects: compared with the prior art, the hanging strip is nailed on the channel wall at the back of the waterproof board body through the hot-melt liner, so that the waterproof board body is fixed, the hanging strip is not easy to fall off and is firm, and the failure of the waterproof function of the tunnel is avoided.
