Method of hanging separate waterproof board without nails

Abstract

A separating type water-proof board nail-free hanging method is used for secondary lining in a tunnel construction process. The method is mainly used for solving the problem that the existing separating type water-proof board hanging construction quality is not easy to control and the like. The method includes that a steel cushion block is machined, and a base plane is cleaned; a steel plate is arranged on the outer side of non-woven fabric, iron nails are shot at the steel plate position by a nail gun, and the non-woven fabric is fixed on a tunnel wall; water-proof board hanging points are welded in a machining factory outside a tunnel; a water-proof batten is machined and welded through a hot wind welding gun according to water-proof board design hanging point requirements, one end of the water-proof batten is welded onto one water-proof board, cloth belts or cotton ropes are tied to the water-proof batten, and the other end of the water-proof batten is welded onto the other water-proof board. The steel plate is arranged on the outer sides of the cloth belts or the cotton ropes on the water-proof board hanging points, the iron nails are shot on the steel plate through the high-pressure nail gun, and the cloth belts or the cotton ropes are fixed on the non-woven fabric. Finally, the two water-proof boards are welded in a hot melting mode. The method has the advantage of being capable of guaranteeing the construction quality.

Description

[0001] Technical field: [0002] The invention relates to a method for hanging a separate waterproof board used for secondary lining in the tunnel construction process. [0003] Background technique: [0004] The current separate waterproof board is hung by spot welding and pasting the waterproof board and the hot-melt plastic pad with a hot air welding torch. A large number of thermoplastic gaskets increase the construction cost; 3. All operations must be completed on the working surface, the hanging time is long, and the work efficiency is low. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a nail-free hanging method for separate waterproof boards with low construction cost, good quality and short hanging time. [0007] The above purpose is achieved in this way: [0008] 1. Use iron pliers or cutting equipment to process a 2.5cm*2.5cm square steel gasket as a spare steel plate; [0009] Second, base surface c...
