Construction method of rubber water stop between culvert slabs covered with soil

Abstract

The invention relates to a water-stop construction method between a prefabricated cover slab and a slab, especially the water-stop between a soil-covered slab and a culvert slab plays an important role and can effectively stop water. The purpose is to overcome the shortcomings of the traditional soil-covered prefabricated slab culvert waterproof construction technology, and provide a construction method that can reduce the construction process, integrate the construction period, and improve the waterproof and water-stop effect. The technical proposal includes the pasting method of the rubber waterstop and the method of assembling and extruding the budget board. The beneficial effects are: (1) the application of the rubber waterstop can expand when encountering water, thereby improving the waterproofness and achieving the purpose of waterstop; (2) it has shrinkability, and is suitable for changes in thermal expansion and cold contraction of the body; (3) Simple operation and improved work efficiency.

Description

[0001] This application is the application number: the application date is: June 3, 2011, and the name of the invention is: construction method of rubber water-stop between soil-covered culverts Technical field: [0002] The invention relates to a water-stop construction method between a prefabricated cover plate and a plate, in particular, the water-stop between the soil-covered cover plate and the plate plays an important role and can effectively stop the water. Background technique: [0003] In the construction of the soil-covered slab culvert, usually the gap between the slab culvert and the slab is not treated, but the slab is waterproofed with a waterproofing membrane, and the upper part of the slab and slab is plugged with asphalt hemp. During wire construction, due to the influence of high asphalt temperature and irregular operation at the construction site, the construction effect is often unsatisfactory, resulting in leakage of about 40% of the earth-covered culvert...

AI Technical Summary

Problems solved by technology

[0005] 1. After the construction of the waterproof membrane, since the covering soil material is granular material, it is rolled by a road roller after construction, and the dynamic load of the vehicle is repeatedly applied, which usually destroys the waterproof membrane and causes water seepage in the culvert;

[0006] 2. There are many construction procedures for asphalt hemp silk, and the process is cumbersome;

[0007] 3. The theoretical water resistance of asphalt hemp silk is good, but the actual operation effect is poor
