Description
Technical Field
The invention belongs to the technical field of building repair, and particularly relates to a concrete crack treatment technology.
Background
When concrete cracks, the prior art is to perform resin sealing, resin grouting, resin filling with a V-shaped groove and other treatment methods on the concrete cracks. The methods have the disadvantages that the method cannot play a substantial restraint role in controlling and expanding the cracks, only seals and heals and fills the concrete cracks, has higher requirements on cleaning the cracks and interface cleaning and strength. The problems of surface sealing cracks, grouting filling cracks and V-shaped groove embedding cracks are that dynamic cracks continue to appear. The interface is a weak node, a crack may be changed into two cracks, and the problem of the crack cannot be thoroughly solved.
Disclosure of Invention
The invention provides a concrete crack treatment technology aiming at the problems provided by the background technology, which can effectively recover the bearing capacity of a member or improve the bearing capacity of the member and restrain the expansion of cracks.
The technical scheme of the invention is as follows: a concrete crack treatment technology specifically comprises the following steps:
1. designing, selecting and arranging a high-strength restraint band;
2. duplicating the shape and the position of the section embedded with the high-strength restraint belt on the surface of the concrete;
3. punching and cutting the high-strength restraint belt;
4. cleaning holes and cutting seams;
5. preparing resin and pouring the resin;
6. installing a high-strength restraint belt;
7. sealing the high-strength restraint band and the original cracks;
the high-strength restraint strap comprises two end anchoring pieces and a connecting part for connecting the end anchoring pieces, wherein the connecting part is made of a composite material of a carbon fiber woven strap and resin; the connecting component mainly plays a role in resisting tensile force, and the end anchoring component mainly plays a role in fixing, restraining and resisting tensile pulling.
Furthermore, the form of the high-strength restraint strap is in a shape like a Chinese character 'yi' or 'X'.
The invention has the beneficial effects that:
1. the technology can effectively recover the bearing capacity of the member or improve the bearing capacity of the member and restrain the expansion of cracks by installing the high-strength restraint belt.
2. The corrosion resistance and durability are good, the treatment effect is obvious, the capability of the high-strength restraint belt can be fully exerted, and the end part restraint anchoring piece can fully exert the function to resist slippage.
3. The construction is simple, the installation quality is reliable, the construction efficiency is high, time and labor are saved, and the cost is saved.
