Problems solved by technology

[0002] When the existing underwater inverted crack repair technology uses ordinary mortar to repair underwater inverted cracks, there are the following defects: it is easy to disperse into muddy water, sinks without adsorption, the slurry sinks freely due to gravity, the filling rate is less than 5%, and it is difficult for ordinary slurry to enter Micro-crack filling, insufficient drainage
When repairing underwater inverted cracks, it is difficult to repair with ordinary mortar, which will cause waste of resources, high cost, and it is difficult to repair the edge of the crack. It is even impossible to repair the local small extended cracks around the main cracks, an

Abstract

The invention provides a device and a method for repairing an underwater inverted crack by magnetic mortar. The device comprises a guide cylinder, a clamping mechanism, a launching mechanism and a magnetic nail, wherein the clamping mechanism and the launching mechanism are arranged in the guide cylinder; the magnetic nail is positioned in the guide cylinder and clamped by the clamping mechanism; an inflator pump is used for inflating the guide cylinder to enable a launching cylinder of the launching mechanism to have potential energy; a launching button is triggered to release the launching cylinder to obliquely shoot the magnetic nail into the periphery of the underwater inverted crack; and the magnetic mortar is injected into the crack to be adsorbed with the magnetized magnetic nail. The device and the method solve the problems that the original underwater inverted crack is easy to fall off after being repaired and a local tiny crack cannot be repaired, and have the characteristics that the structure is simple, water and air in the crack are extruded to repair the crack, the shear strength of a crack interface is improved, a repair area is not easy to fall off, the device is safe and reliable, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of underwater restoration, and relates to a device and method for repairing underwater inverted cracks with magnetic mortar. Background technique [0002] When the existing underwater inverted crack repair technology uses ordinary mortar to repair underwater inverted cracks, there are the following defects: it is easy to disperse into muddy water, sinks without adsorption, the slurry sinks freely due to gravity, the filling rate is less than 5%, and it is difficult for ordinary slurry to enter Micro-cracks are filled and drainage is insufficient. When repairing underwater inverted cracks, it is difficult to repair with ordinary mortar, which will cause waste of resources, high cost, and it is difficult to repair the edge of the crack. It is even impossible to repair the local small extended cracks around the main cracks, and the repair effect is very poor. [0003] In the existing underwater inverted crack ...
