Embedded anchoring type concrete crack repairing process

Abstract

The invention discloses an embedded anchoring type concrete crack repairing process, and belongs to the technical field of concrete repairing. A repairing rod is inserted into a repairing groove cavity, a plurality of transverse anchoring rods with the inner ends bonded with inner embedded rods are distributed on the end wall of an outer inserting rod from bottom to top, after a heated crack repairing agent is injected into the repairing groove cavity through the inner embedded rods, the inner embedded rods are heated to enable the inner ends of the transverse anchoring rods to be separated from the inner embedded rods and the outer inserting rod in sequence, a plurality of transverse anchoring rods are embedded into the crack repairing agent, the outer tip ends of the transverse anchoringrods are inserted into the repairing groove cavity to achieve the anchoring effect, then the outer inserting rod is pulled out upwards, secondary material injection is carried out, a concrete supplementing layer is formed in the crack repairing cavity, the inner embedded rods, a conical material guide part and the plurality of transverse anchoring rods are embedded into the repairing groove cavity, and the multiple transverse anchoring rods are distributed up and down, so that the transverse bonding degree between the concrete supplementing layer and the repairing groove cavity and the overall mechanical strength are effectively enhanced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of concrete repair, and more specifically relates to a pre-embedded anchorage type concrete crack repair process. Background technique [0002] In recent years, with the continuous development of building waterproof technology and the continuous improvement of my country's building waterproof standards, regulations, etc., the leakage rate of my country's housing construction has continued to decline, and the nationwide and large-scale leakage problems have been initially contained, but underground The leakage problem of the building is still not optimistic. [0003] There are many reasons for the formation of concrete cracks, which can be roughly divided into two categories: one is the cracks caused by the action of load, which is called load cracks. There are two main types of cracks under load: direct cracks and secondary stress cracks. The direct crack refers to the crack caused by the direct stress gene...

Problems solved by technology

The disadvantage of these methods is that the control and expansion of the cracks can not play a substantial role in restraint, only the concrete cracks are closed, healed and filled, and the repair interface is a weak node in the concrete crack repair process, and the repair material is not easy to mix with The end face of the crack is bonded with high strength, the repair strength is lacking, and the repaired part is easy to fall off from the crack, so it is difficult to achieve a good repair effect
