Problems solved by technology

However, the above-mentioned construction technology cannot repair the depression with a thickness of less than 3mm, and the connection force between the high-strength concrete beam itself and the epoxy mortar is not enough, and the construction is troublesome.
In addition, the use of asphalt to maintain roads also has the disadvantage of not being able to repair depressions with a thickness of less than 3mm.

Embodiment

[0046] 1. First, chisel the recessed parts, then clean the slag and dust, and finally clean the chiseled parts with acetone (cleaning must be thorough, all parts must be cleaned);

[0047] 2. Repair materials:

[0048] Adhesive agent: composed of epoxy resin, acetone and ethylenediamine, the ratio is 100:12:15;

[0049] Aggregate: Carborundum, the dosage is 8-10 times of that of cement.

[0050] 3. Repair operation: (1) Mix epoxy resin, acetone, and ethylenediamine in a clean plastic container according to the above ratio to prepare adhesive agent, according to weather conditions, environment, construction requirements, etc.; (2) Put The prepared adhesive is applied to the parts that need to be repaired, and the application should be uniform and the thickness should be moderate; (3) Sprinkle a layer of emery on the applied resin glue, (the amount of emery is 8-10 times that of epoxy resin according to the site Condition adjustment) and rub repeatedly with a brush until unifo...

Abstract

The invention discloses a road bridge repair curing agent and a road bridge repair method, wherein the road bridge repair curing agent includes gluing agent and aggregate, wherein the gluing agent includes resin, acetone and ethanediamine; the aggregate is carborundum. According to the road bridge repair curing agent, the resin is associated with the carborundum, and practice is more convenient; the road bridge repair curing agent can effectively repair the sunken with less than 3 mm thickness, and has good connecting force to the high-intensity concrete.

Description

technical field [0001] The invention belongs to the field of concrete materials, in particular, the invention relates to a road and bridge repairing and curing agent and a road and bridge repairing method. Background technique [0002] At present, there are many materials and methods for pavement repairing, such as using resin glue as a foundation, and then using resin mortar to repair defective parts. But above-mentioned construction technology can't mend the depression that thickness is less than 3mm, and for high-strength concrete beam body itself and epoxy mortar connection strength is not enough, construction trouble. Adopt asphalt maintenance road to exist in addition and can't mend the sunken shortcoming that thickness is less than 3mm equally. For this reason, for the method for current bridge repairing, still need further improvement. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least ...
