Embodiment 1

[0013] Take 65kg of cement, 10kg of No. 1 tunnel, 12kg of 707 glue, 0.8kg of cellulose, 2.4kg of aluminum silicate, first soak the cellulose in water for at least 5 hours to obtain colloidal cellulose; then place No. 1 tunnel , 707 glue and colloidal cellulose are mixed, and then stirred evenly to obtain a solution of consistent color; gradually add aluminum silicate and cement to the above-mentioned solution that is evenly stirred, and stir evenly while adding. If the viscosity is high, it can be Add water to dilute, then mix evenly to meet the construction requirements; it is best to apply the above solution evenly to the surface of the bridge cement concrete with a thickness of 1mm. The viscosity of the solution can be adjusted with the season. Treatment of the working surface before construction: First, keep the construction surface clean and dust-free, with a certain degree of moisture, so that the waterproof layer can be well combined with the bridge deck concrete.

Embodiment 2

[0015] Take 70kg of cement, 13kg of No. 1 tunnel, 10kg of 707 glue, 1kg of cellulose, 2.5kg of aluminum silicate, mix into a homogeneous emulsion according to the aforementioned sequence and requirements, and smear it on the surface of the bridge cement concrete with a thickness of 2mm.

Embodiment 3

[0017] Take 80kg of cement, 15kg of No. 1 tunnel, 10kg of 707 glue, 1.5kg of cellulose, and 2.3kg of aluminum silicate, mix them into a homogeneous emulsion according to the aforementioned sequence and requirements, and smear it on the surface of the bridge cement concrete with a thickness of 2mm.

Abstract

The invention discloses a waterproof material for a bridge floor. The waterproof material comprises the following components, by weight, 65-80 parts of cement, 5-15 parts of Daokong 1, 10-25 parts of a 707 glue solution, 0.5-2 parts of cellulose and 2-2.5 parts of alumina silicate. The invention also discloses a construction method of the waterproof material for the bridge floor. The construction method comprises the following steps: 1, immersing the cellulose in water to obtain gummy cellulose; 2, weighing and mixing the Daokong 1 and the 707 glue solution, mixing them with the gummy cellulose, and uniformly stirring; 3, weighing alumina silicate and cement, gradually adding them to the uniformly stirred solution obtained in step 2 under uniformly stirring; and 4, uniformly smearing the solution obtained in step 3 to the cement concrete surface of a bridge. The waterproof material of the invention, which utilizes macromoleclar polymers to generate a reaction and forms continuous nets mutually penetrating and crosslinking with each other on the cement concrete surface of the bridge to generate a hydrophobic structure with polymer performances, allows long-term load bearing requirements of the bridge floor to be improved, structure destroy and concrete carbonization caused by water seepage to be prevented and the service life of the bridge to be prolonged.

Description

Technical field [0001] The invention relates to a waterproof material, in particular to a waterproof material with high waterproofness, high impermeability, fire prevention and high temperature resistance, which is used for bridge deck waterproof materials and a construction method thereof. Background technique [0002] At present, during the use of the bridge deck in the road, in rainy and snowy weather, the rainwater penetrates the asphalt concrete surface to reach the surface of the cement concrete. Due to the poor waterproof effect of the concrete, the water continues to penetrate into the interior of the cement concrete of the bridge deck and freezes outside at low temperature. During the thawing period, due to the frost heaving effect of internal moisture, the concrete structure was destroyed and the concrete became loose, which caused potholes to be destroyed on the bridge deck. How to improve the waterproof effect of bridge deck concrete and prevent moisture from entering...
