Description

Technical Field

[0001] The utility model relates to the technical field of grouting equipment, in particular to a stirring device for grouting construction. Background Art

[0002] Grouting technology plays an important role in underground structure waterproofing, foundation pit reinforcement, prevention of ground subsidence, foundation treatment of existing structures, and jacking and friction reduction. For tunnel engineering, grouting has filling, reinforcement and seepage reduction effects. Grouting devices are usually required for grouting in highway tunnels. Existing grouting and stirring devices usually need to pour the slurry into the device for temporary storage before grouting. The slurry will coagulate randomly during storage, affecting the quality of the slurry. Moreover, because the slurry has a certain viscosity, a lot of slurry will adhere to the inner wall and bottom of the storage container during grouting and cannot be discharged, resulting in slurry waste. Moreover, the attached slurry will gradually solidify into a hard shell on the inner wall of the container, which is difficult to remove. As the hard shell becomes thicker, the volume of the container will also become smaller.

[0003] For this purpose, we design a mixing equipment for construction grouting. Utility Model Content
