Road and bridge waterproof construction method

Abstract

The invention aims at providing a road and bridge waterproof construction method. The road and bridge waterproof construction method comprises the steps of spraying a cross-linking agent layer on a concrete substrate which meets construction standards and then spraying waterproof paint for roads and bridges to form a waterproof layer; after the waterproof layer is dried, conducting waterproof construction by way of paving a cement concrete pavement or an asphalt concrete pavement. The road and bridge waterproof construction method solves the problem that waterproof sealing treatment for a road or a bridge in the waterproof sealing field is prone to be affected by such elements as the environmental hot and humid cycling, the vapor expansion and the basement layer movement; after the waterproof construction is conducted according to the road and bridge waterproof construction method, the waterproof effect is good, the degree of environmental resistance is high, the durability is achieved and the practical value is quite high.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a road and bridge waterproofing construction method. Background technique [0002] In the prior art, improper waterproof materials on the bridge surface will cause water seepage on the bridge deck, corrosion of steel bars, spalling of the pavement layer, alkali-aggregate reaction, and concrete expansion due to steel bar corrosion, which seriously affects the bridge. Durability and normal service life. Therefore, people pay more and more attention to the waterproof treatment of road bridges. [0003] At present, the waterproof treatment of road and bridge surfaces mostly uses road and bridge waterproof coatings, modified asphalt pre-paved waterproof membranes or modified asphalt composite waterproof membranes for waterproofing. In particular, road and bridge waterproof coatings are the most widely used. Road and bridge waterproof coatings are mainly composed of emulsified m...

AI Technical Summary

Problems solved by technology

The waterproof membranes seen in the market are mainly modified asphalt waterproof membranes and polymer sheets. The construction methods are mostly hot-pressed construction or oily base oil, oily base oil, and polymer glue bonding, which has high consumption. Energy, danger, heavy environmental pollution, wet base surface construction bonding is not firm; the waterproof membrane bonded with polyvinyl alcohol latex cement adhesive and other polymer latex cement adhesive is very easy to be affected by the environment, so that Decreased cohesive force, resulting in the process of desorption and mortise and tenon removal, and loses the sealing and waterproof effect

[0009] For the above-mentioned waterproof coating and waterproof coiled material, due to the influence of factors such as environmental humidity and heat cycle, water vapor expansion, and grass-roots movement, the problem that its waterproof and sealing performance is reduced or even lost is an urgent need to be solved in the prior art.
