Low-pressure concrete structure crack repairing device and repairing method

Abstract

The invention discloses a low-pressure concrete structure crack repairing device and repairing method. The device comprises a liquid storage barrel, a stirring mechanism, and an extrusion mechanism; the liquid storage barrel comprises a shell body and a liquid outlet head; the two ends of the shell body are open. The liquid outlet head is mounted at the lower end of the shell body; the liquid outlet head is detachably connected with the shell body; the stirring mechanism comprises a stirring frame and a driving mechanism; the output end of the driving mechanism is fixedly connected with one end of the stirring frame; the stirring frame is installed in the middle inside the shell body; the driving mechanism is installed at the upper end of the shell body and connected with the shell body ina sealed mode; one end of the extrusion mechanism is arranged inside the middle of the shell body in an up-down sliding mode; and the other end of the extrusion mechanism penetrates through the driving mechanism and is arranged in a sliding mode relative to the driving mechanism. In an injection process, a user can accurately control the injection speed through a supporting rod, and the user canoperate and use the device more flexibly.

Description

technical field [0001] The invention relates to the technical field of concrete structure crack repair equipment, in particular to a low-pressure concrete structure crack repair device and repair method. Background technique [0002] Concrete crack surface repair method, the commonly used method is the coating method, increasing the overall surface layer, pressing and applying epoxy mortar, epoxy slurry sticking glass mesh cloth, surface stitching, etc., coating method: a large number of surfaces appear on the concrete surface When there are cracks, use manual or mechanical spraying method to apply the repair material on the concrete surface to play a role of surface sealing. The thickness of the coating film is between 0.3-2.5mm. Considering the conditions of use and crack activity, etc., epoxy asphalt coatings, polyurethane coatings, polyurethane asphalt coatings and other rigid coatings can be used for wear-resistant floors, and polyurethane elastomers can be used for uns...

AI Technical Summary

Problems solved by technology

[0003] The inventors of the present application have found that the existing equipment used for repairing concrete cracks has a simple structure and can only be simply pressed and injected during use. The one-time extrusion is complete, which is difficult to operate, and it is easy to be blocked during use, which affects the normal injection of the equipment. At the same time, it is also prone to uneven injection during the injection operation, which affects repairing quality
