Problems solved by technology

The impact of cracks on the safety of building structures is also increasing, which greatly reduces the service life of building structures
At present, artificial grouting is the main method of repairing concrete cracks. The cost of repairing this method is huge, and the repair is short-lived, and secondary cracking will occur over time.
Self-repair has become a current research hotspot. Many researchers are actively exploring the self-repair method of concrete cracks. The microbial repair method has been developed, but its problems are: high cost and harsh living conditions for microorganisms.

Embodiment Construction

[0033] like figure 1 As shown, a magnetic slurry capsule system for repairing concrete cracks includes a repairing capsule, the repairing capsule includes a capsule shell 1, and a separator 2 is arranged in the capsule shell 1 to separate the capsule shell 1 into two cavities 101, two The space size ratio of the cavity 101 is 4:1, and the magnetic slurry 3 and the curing agent 4 are respectively arranged in the cavity 101 .

[0034] The capsule shell 1 includes a first half-shell 102 and a second half-shell 103, the separator 2 and the second half-shell 103 are sequentially buckled on the open end of the first half-shell 102, and the separator 2 is a cover-like structure.

[0035] In specific use, the capsule shell 1 is designed with a double locking system. First, the magnetic slurry 3 is placed in the first half shell 102, and the separator 2 is set for pre-locking, and the curing agent 4 is placed in the second half shell 103. The second half shell 103 and the first half s...

Abstract

The invention provides a magnetic slurry capsule system for concrete crack repair and a construction technology, the magnetic slurry capsule system comprises a repair capsule, the repair capsule comprises a capsule shell, a separation sheet is arranged in the capsule shell to divide the capsule shell into two cavities, and magnetic slurry and a curing agent are respectively arranged in the cavities. The system and the construction technology are applied before concrete pouring, when cracks are generated, the system and the construction technology can play a role automatically, repair the concrete cracks and enhance the cohesive force between reinforcing steel bars and concrete, a large amount of manpower is not needed, the labor intensity is low, and the method is simple.

Description

technical field [0001] The invention relates to a crack repairing technology, in particular to a magnetic slurry capsule system and a construction technology for repairing concrete cracks. Background technique [0002] Concrete cracks are physical structural changes caused by internal and external factors of concrete structures, and cracks are the main reason for the reduction of concrete structure bearing capacity, durability and waterproofing. When micro-cracks occur in concrete, the ingress of moisture and oxygen can cause corrosion of the steel bars inside it. The impact of cracks on the safety of building structures is also increasing, which greatly reduces the service life of building structures. At present, the method of manual grouting repair is mainly used for concrete crack repair. The repair cost of this method is huge, and the repair is short-lived, and secondary cracks will occur over time. Self-healing has become a current research hotspot. Many researchers a...
