Grouting device for ecological restoration of concrete cracks

Abstract

The invention discloses a grouting device for ecological restoration of concrete cracks. The grouting device comprises a box body I and a box body II which are arranged side by side. A grouting hole I, a grouting hole II and a grouting hole III are formed in an adjusting base. The bottom of the box body I communicates with the grouting hole II. The bottom of the box body II communicates with the grouting hole I. A guide pipe is arranged at the bottom of the adjusting base. An adjusting assembly used for controlling the grouting hole I and the grouting hole II to be opened and closed is arranged in the adjusting base. A steel wire vertically and movably penetrates through the box body II and the adjusting base and then extends towards the tail end of the guide pipe. A semicircular end is arranged at the end of the guide pipe. A plurality of grout spraying holes are formed in the side wall of the guide pipe. According to the grouting device, the MICP technology is applied to filling of the concrete component cracks, meanwhile, leakage point positions in the deep positions of the cracks can be blocked in a targeted mode, the diffusion efficiency of grout is improved, and thus the blocking effect is improved.

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
