Water conservancy project waterproof roll construction method

Abstract

The invention relates to a water conservancy project waterproof coiled material construction method. According to the construction method, a pasting and folding device is used, the pasting and folding device comprises an operation frame, a rotating device, a turnover frame, a lifting device and a smoothing device. According to the construction method, the smoothing device is adopted, a driving motor is started, the output end of the driving motor drives a center rotating shaft to rotate, the center rotating shaft rotates to drive a gear to rotate, the gear rotates to drive two rack plates to move repeatedly, the operation frame continues to be pulled backwards, and therefore when the waterproof coiled material is laid on the foundation, flattening and attaching of the waterproof coiled material are conducted while laying is conducted, redundant air on the attaching face of the coiled material and the foundation is squeezed out, a sliding rod on an edge folding plate does not make contact with a foundation any more, the sliding rod drives a driving plate to move rightwards when moving rightwards, the driving plate drives a push rod to move rightwards when moving rightwards, the push rod drives the edge folding plate to conduct edge folding on the waterproof roll and the corner of the foundation when moving rightwards, and therefore edge folding of the waterproof roll at the corner of the foundation is achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a construction method of a water conservancy engineering waterproof coiled material. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits; [0003] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building, it is the first barrier for the waterproofing of the whole project, and it plays a vital role in the whole project. The most common application is the laying of waterproof membranes on the foundation surface; [0004] Existing paste-folds have the following problems: [0005]...

AI Technical Summary

Problems solved by technology

[0005] (1) When laying and pasting waterproof membranes, usually rolls of membranes are directly spread on the foundation through the cooperation of two people, and then the laid waterproof membranes are smoothed, so it is laborious and laborious. The existing device cannot realize the simultaneous laying and smoothing of the waterproof membrane on the base;

[0006] (2) After the waterproof membrane and the foundation are pasted, there is excess air on the pasting surface with the foundation, so air bubbles will be generated, and the existing device cannot remove the excess air generated between the membrane and the foundation;

[0007] (3) When the waterproof membrane is laid on the corner of the foundation, in order to make the waterproof membrane and the foundation more sealed and the laying effect better, it is necessary to fold the membrane laid at the corner, which cannot be realized by the existing device Hemming after laying
