Concrete crack surface cut groove sealing and blocking structure and method

Abstract

The invention discloses a concrete crack surface cut groove sealing and blocking structure and a concrete crack surface cut groove sealing and blocking method. Through adopting the small-width-to-depth-ratio cut groove sealing and blocking technology, concrete cracks can be effectively repaired or reinforced. Firstly, a proper handheld angle grinding machine is adopted, a matched and proper angle grinding machine is selected for grinding sheets, the concrete is cut into a plurality of end-to-end fold lines along the cracks or construction seams, the cutting is completed, pressure water is adopted for clean flushing, accumulated water in the grooves is naturally dried in the air or is dried through blowing, then, cementing materials are filled for seam sealing, and when the cutting seams need to be widened, a double-angle grinding machine can be adopted for grinding sheet parallel cutting. The structure and the method provided by the invention have the advantages that the construction is fast and convenient, economy and applicability are realized, the environment is protected, and good economic benefits and social benefits are realized.

Description

technical field [0001] The invention relates to concrete engineering, in particular to a structure and a method for sealing grooves on the surface of concrete joints. Background technique [0002] The causes of concrete cracks are complex and diverse, and even have multiple factors interacting with each other. It is one of the common technical problems and frequent and common defects in concrete engineering. Due to the existence of cracks, the light ones affect the appearance of the building, and the severe ones affect the durability of the building, destroy the integrity and endanger the safe operation of the building. Therefore, people always try their best to discover every crack that has appeared in time, and then carefully inspect, observe and analyze the causes, and classify them. The "prescribe the right medicine" is the best repairing and treatment plan, and deal with it in a timely manner. [0003] At present, there are two purposes of repairing and reinforcing con...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the large volume of chiseling, the parent concrete is greatly damaged, and the thin-walled structure is not suitable;

[0006] 2. Due to the large volume of the trough and the manual work, the labor intensity of the construction personnel is increased and the work efficiency is low, and the "fat" of the trough body increases the amount of filling materials and increases the project cost;

[0007] 3. When the concrete has appearance requirements, it will affect the appearance of the concrete;

[0008]4. For cracks on vertical or inclined surfaces, some filling materials tend to go down before solidification due to their own weight when sealing the cracks with the grooving method. flow to disengage the upper part, etc.
