Embodiment Construction

[0040] Such as Figure 1 to Figure 4 As shown, this embodiment provides a method for repairing discontinuous cracks in a concrete building body, and the discontinuous cracks 2 are located on the top plate, bottom plate or side wall of the concrete building body 1 .

[0041] The method for repairing the discontinuous crack of the concrete building body comprises the following steps:

[0042] Step 1. Crack Marking

[0043] Such as figure 2 As shown in I, each discontinuous crack 2 is marked along the trend of the crack 2 of the concrete building body 1, and the position of the crack 2 to be repaired is determined.

[0044] Step 2. Groove along the crack

[0045] Such as figure 2 As shown in II, the groove 3 is excavated along the crack 2 of the concrete building 1 on the surface of the concrete building 1. In this embodiment, the groove 3 is arranged along the length direction of the crack 2 of the concrete building 1. The opening center position of the crack 2 is excavat...

Abstract

The invention provides a repairing method of inconstant cracks of a concrete building body. The method comprises the steps of step one, crack marking; step two, groove forming along the cracks; step three, hole drilling in oblique directions; step four, groove top sealing; step five, glue injection mouth installing; step six, glue injection; step seven, surface finishing. The method has the advantages that the difficult problem of the repairing of the inconstant cracks on the concrete building body is solved, a communicated space is created for the glue injection process of the cracks so thatglue can completely fill cracking regions, the repairing effect of the inconstant cracks on the concrete building body is significantly improved, the durability and safety of a concrete structure is enhanced, the operation is convenient, construction is easy, the repairing construction efficiency is high, large equipment is not needed, construction can be conducted in various complicated environments, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of concrete crack repair, in particular to a method for repairing discontinuous cracks in concrete buildings caused by concrete plastic shrinkage, drying shrinkage, template disturbance during concrete pouring, and the like. Background technique [0002] In urban subway projects, the phenomenon of water leakage in concrete structures is very common, and most of the water leakage already existed before the station was put into use, and only simple sealing or partial plugging treatment was adopted during the construction period. Commonly used treatments include glue injection (including epoxy or polyurethane) without joint sealing, and painting with inorganic materials (cement-based penetrating crystalline materials). Cracks are usually wide on the surface and narrow inside. If the glue is injected under pressure without sealing the crack, the glue will not move too much in the depth direction of the crack, an...
