A grouting device for ecological restoration of concrete cracks

Abstract

The invention discloses a grouting device for ecological restoration of concrete cracks, which comprises box body I and box body II arranged side by side, and a grouting hole I, a grouting hole II and a grouting hole III are opened on the adjustment base, and the box body The bottom of I is connected to the grouting hole II, and the bottom of the box body II is connected to the grouting hole I. There is a guide pipe at the bottom of the adjustment base, and there is a guide pipe in the adjustment base for controlling the opening of the grouting hole I and the grouting hole II. Closed adjustment assembly; the steel wire moves vertically through the box body II, and after the adjustment base extends to the end of the guide guide tube, the end of the guide guide tube is provided with a semicircular end, on the side wall of the guide guide tube There are multiple spray holes. The present invention applies the microbe-induced deposition of calcium carbonate (MICP) technology to fill the cracks of concrete members, and at the same time, it can realize the targeted sealing of leakage points deep in the cracks, enhance the diffusion efficiency of slurry, and further improve the sealing effect.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a grouting device for ecological restoration of concrete cracks. Background technique [0002] Concrete components are widely used in the field of civil engineering because of their high strength, easy access to materials, strong moldability, and good integrity. However, concrete is a typical porous and brittle material. Affected by unfavorable factors such as temperature changes and corrosion aging, under long-term loads, cracks of various widths will inevitably develop inside components due to damage accumulation, which will reduce the mechanical properties of components and threaten the durability of structures. sex. Traditional concrete structure crack repair methods such as surface sealing method, grooving filling method, and grouting plugging method have a series of problems such as high energy consumption, high cost, unfriendly environment, and even secondary damage t...

AI Technical Summary

Problems solved by technology

In the prior art, in view of the problem of various width gaps in the interior of concrete components due to the accumulation of internal damage under long-term loads, repair methods such as surface sealing method, grooving filling method, and grouting plugging method are usually used. The repair method not only has high construction costs and is not friendly to the environment, but can also lead to secondary damage to concrete components. In view of the above defects, the applicant has developed a grouting device, which applies the technology of microbial induced calcium carbonate deposition (MICP) It is suitable for filling the cracks of concrete components, and at the same time, it can realize the targeted sealing of the leakage points deep in the cracks, enhance the diffusion efficiency of the grout, and then improve the sealing effect
