Embodiment 1

[0017] Embodiment 1: Get 54kg of cement, No. 13kg of Daokong, 11kg of 707 glue, 1.5kg of aluminum silicate and 1.0kg of cellulose, first soak the cellulose in water for at least 6 hours to make the cellulose colloidal; Mix Daokong No. 1, 707 glue and the above-mentioned colloidal cellulose, and then stir until the color is uniform; gradually add aluminum silicate and cement to the above-mentioned uniformly stirred solution, and stir while adding until uniformly stirred. If the viscosity is high, it can be diluted with water, and then stirred evenly to meet the construction requirements; finally, the solution mixed according to the above-mentioned order and requirements is evenly applied to the cement concrete of the bridge deck, with a thickness of 1.5mm. The viscosity of the solution can be adjusted with the seasons. Treatment of the working surface before construction: first, keep the construction surface clean and dust-free, with a certain degree of humidity, so that the wa...

Embodiment 2

[0018] Example 2: Take 71.6kg of cement, 15.9kg of No. 1 tunnel, 10kg of 707 glue, 2kg of aluminum silicate and 0.5kg of cellulose, mix into a uniform emulsion according to the aforementioned order and requirements, and smear it on the cement concrete surface of the bridge deck , the thickness is 2.0mm.

Embodiment 3

[0019] Example 3: Take 67.7kg of cement, 15.9kg of No. 1 tunnel, 13.9kg of 707 glue, 1.5kg of aluminum silicate, and 1kg of cellulose, mix them into a uniform emulsion according to the aforementioned order and requirements, and apply it to the cement concrete surface of the bridge deck On, the thickness is 1.8mm.

Abstract

The present invention discloses one kind of waterproof bridge floor material and its construction process. The waterproof bridge floor material consists of cement 55-85 weight portions, No. 1 road hole material 10-25 weight portions, No. 707 glue 5-25 weight portions, cellulose or short fiber 0.5-1.5 weight portions and aluminum silicate 1-2.5 weight portions. The present invention is used for waterproofing of cement concrete on bridge floor, and can form hydrophobic interpenetrating polymer network on the surface of cement concrete to block water and increase the service life of bridge floor. It is applied through simple smearing.

Description

technical field [0001] The invention relates to a bridge deck waterproof material and a construction method thereof. Background technique [0002] At present, during the use of the bridge deck on the road, when it encounters rainy and snowy weather, the rainwater penetrates the asphalt concrete surface to reach the surface of the cement concrete. Because the waterproof effect of the concrete is not good, the water continues to infiltrate into the interior of the cement concrete of the bridge deck. During the freezing and thawing period of the external low temperature, due to the freezing effect of the internal moisture, the concrete structure is damaged, the concrete is loose, and the bridge deck is damaged by pits. How to improve the waterproof effect of bridge deck concrete and prevent moisture from entering the interior of cement concrete bridge deck, there are many methods currently used, such as spraying hot asphalt, modified asphalt, and paving waterproof membranes on ...
