Abstract

The invention discloses a novel waterproof board laying construction method and belongs to the field of tunnel construction. The method includes the following steps: fixing slave pieces on a tunnel excavating outline face with organic hooks facing the outside; connecting the slave pieces and master pieces in a contact pressing overlapping mode through the hooks and threads to form joints, removing a hot melt adhesive protection film on the back of each master piece, bonding waterproof boards to the hot melt adhesive faces of the backs of the master pieces in a contact pressing mode, repeating the steps for multiple times and arranging the slave pieces and the master pieces on the arch crown, the lateral wall and a base board the tunnel excavating outline face to finish laying of the waterproof boards on the tunnel excavating outline face. Compared with a waterproof board laying construction method in the prior art, the novel waterproof board laying construction method utilizes the characteristics of snap fastener pieces, the waterproof boards are laid on the tunnel excavating outline face, a waterproof board laying operation process is simplified, laying construction efficiency is improved, labor intensity of workers is reduced, and laying cost is saved. Meanwhile, the waterproof boards cannot be damaged in the laying process, and waterproof board completeness and laying quality are ensured.

Description

[0001] technical field [0002] The invention relates to a new construction method for laying waterproof boards, which belongs to the field of tunnel construction. Background technique [0003] With the large-scale construction of highways, railways, and urban rail transit, the number of tunnel projects as an important structural form is increasing, and the scale is getting larger and larger. The tunnel waterproof project is an important project to ensure the safe operation of the tunnel, and has been subject to construction units. And the great attention of the owners. Especially electrification and high-speed rail. Tunnel waterproofing and water leakage remediation projects have become key projects, and the investment is huge. [0004] The traditional method of laying waterproof boards generally adopts the hot-melt pad anchor welding method, which requires about 10 people to operate at the same time, of which 4-6 people stand on the laying platform and use wooden sticks...
