Repairing device for through crack of building wall

Abstract

The invention discloses a repairing device for a through crack of a building wall, and relates to the technical field of building wall through crack repairing. The repairing device comprises a material injection barrel, a transmission mechanism is movably installed at the upper end of the material injection barrel, a dust collection mechanism is movably installed on the inner side of the upper end of the material injection barrel, and the lower end of the dust collection mechanism is rotatably connected with the upper end of the transmission mechanism through a cross push rod. An injection head is fixedly installed in the center of the top of the material injection barrel, a magnetic ball is arranged on the inner side of the injection head, and the cross push rod is movably installed on the inner side of the material injection barrel. According to the repairing device, the transmission mechanism drives an adsorption mechanism to work, so that the adsorption mechanism is driven to work, static electricity is generated, dust is adsorbed during collision, and the influence of dust and crushed soil blocks in the through crack on crack sealing is avoided when the crack is sealed by daubs. Therefore, EA resin rubber can seal the through crack more effectively.

Description

technical field [0001] The invention relates to the technical field of repairing through cracks in building walls, in particular to a repairing device for through cracks in building walls. Background technique [0002] Penetrating cracks refer to penetrating through the entire concrete structure layer, which will destroy the integrity of the structure and change the stress conditions of the concrete, so that the local or even the overall structure may be damaged, which will seriously affect the quality and operation safety of the building. Existence and development usually cause corrosion of internal steel bars and other materials, reduce the bearing capacity, durability and impermeability of reinforced concrete materials, affect the appearance and service life of buildings, and seriously threaten people's lives and property safety , Many engineering accidents are caused by the unstable development of cracks, which are caused by various reasons: raw materials, construction t...

[0002] Penetrating cracks refer to penetrating through the entire concrete structure layer, which will destroy the integrity of the structure and change the stress conditions of the concrete, so that the local or even the overall structure may be damaged, which will seriously affect the quality and operation safety of the building. Existence and development usually cause corrosion of internal steel bars and other materials, reduce the bearing capacity, durability and impermeability of reinforced concrete materials, affect the appearance and service life of buildings, and seriously threaten people's lives and property safety , Many engineering accidents are caused by the unstable development of cracks, which are caused by various reasons: raw materials, construction technology, temperature, maintenance, etc., must be dealt with in a timely and effective manner; For repairing, you need to use a grouting pump to grout in the cracks. Before grouting, you need to use EA resin cement to seal the cracks and bury the grouting nozzle

[0003] At present, the repairing devices for building wall penetrating cracks on the market, when using EA resin cement to seal the wall penetrating cracks, the dust and broken stones in the cracks are easy to mix with the cement, resulting in gaps between the cement and the gaps. Incomplete closure
