Definitions
- the invention relates to a crack repair method for a concrete pavement.
- the existing concrete pavement cracks have problems such as troublesome construction and unsatisfactory repair effects, and need to be further improved.
- the object of the present invention is to provide a construction method for quickly repairing cracks in a concrete pavement with a good zipper type.
- a construction method for quickly repairing cracks in a concrete pavement by a zipper type which is characterized in that it includes the following steps:
- the diameter of the clean crushed stone in step (6) is less than 30mm in continuous gradation, and the washed crushed stone is washed with water.
- the invention has good repair effect, long service life, and can effectively reduce the re-damage rate.
- FIG. 1 is a construction schematic diagram of a repair structure according to an embodiment of the present invention.
- a construction method for quickly repairing cracks in a concrete pavement by a zipper type including the following steps:
- the diameter of the clean crushed stone in step (6) is less than 30mm in continuous gradation, and the washed crushed stone is washed with water.
- the repaired structure after repair includes the repair groove 1 along the length of the crack.
- the repair groove is formed by cutting out the concrete on the left and right sides of the crack.
- the width of the repair groove is 20cm and the depth is 1/2 ⁇ 1/3 of the concrete layer on the pavement.
- the “8” -shaped groove 2 is set at 50cm intervals in the length direction of the repair groove.
- the depth of the “8” -shaped groove is the thickness of the pavement concrete layer, and the arc diameter of the “8” -shaped groove is 20cm. ;
- a repairing layer 3 is provided in the repairing groove and the "8" -shaped groove, and the surface of the repairing layer is flush with the concrete pavement.
- the left and right edges of the repair groove are parallel to each other.

Abstract
Cette invention concerne un procédé de construction pour réparer rapidement une fissure de revêtement en béton d'une manière de type glissière, comprenant les étapes suivantes consistant à : (1) prendre la fissure du béton comme ligne centrale à l'aide d'un stylo marqueur, tracer une ligne parallèle ayant une largeur de 20 cm, et tracer des cercles ayant chacun un diamètre de 20 cm sur la ligne parallèle tous les 50 cm; (2) percer des trous dans une position circulaire à l'aide d'un foret; (3) découper le béton, buriner béton dans la plage à l'aide d'un pic pneumatique, la profondeur de burinage étant égale à 1/2 à 1/3 d'une couche de béton du revêtement; et (4) nettoyer le béton buriné; mouiller une surface devant être réparée et éliminer l'eau visible; verser enfin un matériau de réparation de type ciment sulfo-alumineux (SC) agité dans un réservoir de réparation et effectuer un vibro-compactage, polir en utilisant un outil à barbes; durcir par pulvérisation d'eau après le durcissement final complet et le durcissement du matériau, et recouvrir le revêtement à l'aide d'un film mince en plastique. Le procédé de construction selon l'invention a un bon effet de réparation et peut réduire efficacement la vitesse de ré-endommagement.
