Multi-point Suspension Laying Construction Method of Tunnel Waterproof Board

Abstract

The invention relates to a structure and method for multipoint suspending laying construction of a tunnel waterproof board. By the adoption of the characteristic that hook-face bands and loop-face bands of hook-and-loop fasteners can adhere to each other and be separated from each other freely, the hook-face bands are fixed to a basic face in parallel according to a preset interval, the loop-face bands are fixed to the back face of the waterproof board in parallel according to a preset interval, after the waterproof board is laid on the basic face, the hook-face bands and the loop-face bands are arranged in a mutually intersecting mode, overlapping points are automatically formed between the hook-face bands and the loop-face bands and are adhesive points, suspending points between the waterproof board and the basic face are formed by the multiple adhesive points, and therefore the waterproof board is effectively suspended through the multiple points. The suspending points do not need to be set manually, point localization in the construction process is not necessary either, the quality of the portion, on the suspending points, of the waterproof board is guaranteed, the looseness margin of waterproof board laying operation can be well controlled, the construction operability and the construction convenience are good, and negative influence on the quality of suspending and laying construction of the waterproof board due to non-smoothness and irregularity of the laying basic face of the waterproof board is avoided.

Description

technical field [0001] The invention relates to a multi-point suspension paving construction structure and a construction method of a tunnel waterproof board, belonging to the technical field of tunnel waterproof engineering. Background technique [0002] In the practice of tunnel waterproofing engineering, the waterproofing board of underground excavation tunnels is generally suspended without nails. There are two main methods: [0003] The first method is to use hot-melt gasket welding for suspension, that is, the waterproof board is directly hot-melt welded on the gasket fixed on the base surface, so as to realize the suspension and fixation of the waterproof board. This method needs to wait until the hot-melt gasket is cooled before forming the adhesive force for the suspension and fixing of the waterproof board; in addition, the welding heating time of the waterproof board is difficult to control, and it is easy to cause scorched welding or virtual welding. If there is...

AI Technical Summary

Problems solved by technology

This method needs to be suspended on the back of the waterproof board, the construction space is narrow, and the operation is difficult; the suspension of the suspenders cannot ensure that the waterproof board near the suspension point is closely attached to the base surface; Conducive to ensuring waterproof quality

[0005] Therefore, there are deficiencies in various degrees in the suspension technology of existing waterproof boards, and there is a need for further technical improvement.
