Abstract

The invention provides a concrete crack repairing device and a concrete crack repairing method, and relates to the technical field of concrete construction. The concrete crack repairing device comprises a protective shell and a water absorption part; the water absorption part is arranged in the protective shell; an opening is formed in the protective shell; and the water absorption part is used for bearing repairing slurry and covering the crack position of concrete at the opening. A constructor places the water absorption part in the protective shell, then pours repairing slurry into the water absorption part to enable the water absorption part to bear enough repairing slurry, then covers the crack position with the opening of the protective shell, and enables the water absorption part toabut against the crack position of concrete from the opening, so that the repairing slurry absorbed by the water absorption part permeates into the crack position. The water absorption part is used for absorbing, bearing and releasing repairing slurry; the protective shell plays roles in protecting, supporting and sealing, so that the infiltration amount of the repairing slurry can be ensured, the infiltration depth of the repairing slurry is deepened, and the crack repair effect is improved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a concrete crack repairing device and a concrete crack repairing method. 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 inter...
