Problems solved by technology

The disadvantage of these methods is that the control and expansion of cracks cannot play a substantial restraint role. Only the concrete cracks are closed and healed and filled. The requirements for cleaning the cracks are relatively high, and the requirements for interface cleaning and strength are also high.
The interface is a weak node, and one crack may become two cracks, and the crack problem cannot be completely solved

[0024] First Example: Combining Figure 1-2 Shown, a kind of concrete crack processing technology provided by the present invention specifically comprises the following steps:

[0025] 1. Select the appropriate type or combination of high-strength restraint bands according to the shape of the crack, and the high-strength restraint bands are in the shape of "one" and "X"

[0026] 2. According to the type or combination of the selected high-strength restraint belt, draw a figure on the concrete surface, and determine the buried section and position of the anchor;

[0027] 3. Drill holes on the concrete at the position of the anchors, and cut grooves between the holes for the installation of the connection;

[0028] 4. Clean up the positions of openings and grooves;

[0029] 5. Inject resin into the holes and grooves;

[0030] 6. Install high-strength restraint belts;

[0031] 7. Surface sealing and coloring treatment.

Abstract

The invention discloses a concrete crack treatment technology. The concrete crack treatment technology comprises the following steps that firstly, high-strength restraint belts are designed, selectedand arranged; secondly, the positions of the high-strength restraint belts are copied on the concrete surface; thirdly, the high-strength restraint belt burying positions are punched and cut; fourthly, hole and cutting joint cleaning is conducted; fifthly, resin is prepared, and resin pouring is conducted; sixthly, the high-strength restraint belts are installed; and seventhly, the high-strength restraint belts and original cracks are closed. According to the technology, through installation of the high-strength restraint belts, the bearing capability of components can be effectively recoveredor the component bearing capability is improved, and crack development is restrained.

Description

technical field [0001] The invention belongs to the technical field of building repairs, and in particular relates to a concrete crack treatment technology. Background technique [0002] When there are cracks in the concrete, the prior art is to carry out resin sealing, resin grouting and V-shaped groove resin filling and other processing methods to the concrete cracks. The disadvantage of these methods is that they cannot substantially restrict the control and expansion of cracks. They only seal and fill concrete cracks, and have high requirements for crack cleaning, interface cleaning and strength. The problem with sealing cracks on the surface, filling cracks with grout, and opening V-shaped grooves to fill cracks is that dynamic cracks continue to appear. The interface is a weak node, and one crack may become two cracks, and the crack problem cannot be completely solved. Contents of the invention [0003] Aiming at the problems raised by the background technology, th...
