[0002] Civil engineering is a general term for the science and technology of building various types of engineering facilities. It refers to the materials, equipment used, and the technical activities such as survey, design, construction, maintenance and repair carried out; it also refers to the object of engineering construction, that is, various engineering facilities built above or below the ground, on land or in water, which directly or indirectly serve human life, production, and scientific research. Therefore, grouting equipment is needed to grout the gaps.

Grouting and repairing are performed on large cracks and small cracks respectively, so that the grouting and repairing effect is better, and the switching is simple and convenient, it is convenient to use, and it is practical, which reduces the time of grouting and repairing and improves the efficiency of grouting and repairing. The device extracts the slurry inside the grouting tube through a grouting pump. When performing civil engineering grouting operations, bubbles may be introduced when the pump body is used to extract the slurry. The presence of bubbles in the gap means that there are gaps between the filling materials, which will directly affect the density and overall strength of the repaired structure. The bubbles reduce the actual contact area, resulting in a decrease in the structural bonding force, thereby reducing the overall bearing capacity of the structure. Therefore, a gap grouting device for civil engineering is proposed to solve the above-mentioned problems. Utility Model Content
