Concrete crack repairing device based on video image technology

Abstract

The invention discloses a concrete crack repairing device based on a video image technology, and belongs to the technical field of video images. The concrete crack repairing device based on the video image technology comprises two pairs of fixing piles fixed to a concrete wall, and a repairing device is attached to a marking film. The repairing device comprises a shell, a sealing ring and a fixing barrel are correspondingly connected to the two ends of the shell, a high-pressure pump is installed in the fixing barrel, a conveying pipe matched with the high-pressure pump is clamped to the fixing barrel, a movable plate is slidably connected into the shell, a pair of electric push rods is fixedly connected to the inner wall of the shell, and the power output ends of the pair of electric push rods are fixedly connected with the movable plate. The movable plate is fixedly connected with a plurality of repairing contacts which are uniformly distributed, so that a crack position is marked on a wall surface at a fixed point through the repairing device, the repairing device can be used for performing centralized repairing on the crack point, fine cracks on the wall surface can be conveniently positioned and repaired, and a repairing trace is relatively shallow.

Description

technical field [0001] The invention relates to the technical field of video images, and more specifically, to a concrete crack repairing device based on video image technology. Background technique [0002] Due to the existence of stone powder and mud powder, machine-made sand concrete has poorer workability than ordinary concrete. However, due to the lack of river sand resources in Guangxi, Yunnan, Fujian and other places, most buildings still use machine-made sand concrete. In the case of improper maintenance of machine-made sand concrete and unreasonable mix ratio, cracking and damage may occur from time to time after form removal, and the occurrence site is often on the facade of walls and piers. [0003] In the prior art, construction personnel use the repair slurry to repair the cracked or damaged part of the concrete, and the repair slurry reacts with the free alkali in the concrete to form stable dendritic crystal colloid, which can effectively block the interior of...

Problems solved by technology

[0004] At present, some cracks on the wall are small and difficult to find when repairing. Although the existing video image technology department scans and shoots the wall to find cracks, but in the construction process, it often uses brushing for construction. Brushing is not only It is not only impossible to guarantee the infiltration amount of the repairing slurry, but it is not conducive to deepening the penetration depth of the repairing slurry. The effect of crack repair is not good, and painting the slurry will also cause some excess slurry to solidify on other parts of the wall, making the There are a lot of protrusions on the wall, which affects the aesthetics of the wall
