Description

Technical Field

[0001] The present application relates to the technical field of grouting devices, and more specifically, to a repair grouting device. Background Art

[0002] When concrete cracks appear on the bridge road beams on both sides of the steel-concrete structure bridge, it is necessary to perform grouting repair on the cracks. Usually, construction workers are required to use a hanging basket to perform grouting repair work on the outside of the bridge road beam, which has low construction efficiency and safety. The existing public technology number CN117888469A proposes a crack repair grouting device for bridge engineering construction. The device blocks high-speed grouting so that the slurry enters the gap of the crack and the gap of the base layer under the action of pressure, thereby effectively preventing secondary cracking caused by the gap still existing in the crack after grouting, and effectively improves the efficiency of crack repair grouting, thereby effectively improving the quality of crack repair. In view of the above-mentioned related technologies, the utility model author believes that the following defects still exist: after the hanger in the comparative literature is hung on the outside of the bridge road beam, it cannot effectively move horizontally along the bridge road beam, and then cannot achieve fast and efficient grouting repair work of cracks in multiple positions, the practicality is reduced, and it is difficult for construction workers to enter the hanger for construction, and it is difficult to repair the cracks. In view of this, we propose a repair grouting device. Utility Model Content
