Description

Technical Field

[0001] The utility model relates to the technical field of grouting construction, in particular to a circulating water curtain grouting device. Background Art

[0002] In order to reduce the seepage volume and the seepage pressure in the hydraulic curtain project, a curtain grouting device is usually used to inject slurry into the cracks and pores of the rock mass or soil layer to form a continuous water-blocking curtain. The circulating hydraulic curtain grouting is carried out by setting up a hydraulic curtain and performing circulating grouting underground to inject the grouting material into the soil or rock to form a solid grouting body. Circulating grouting can improve the grouting effect and ensure that the grouting material fully penetrates into the target area, thereby effectively strengthening the foundation or rock mass. Curtain grouting has always been the main means of anti-seepage treatment of the foundation of hydraulic engineering buildings, and plays an important role in ensuring the safe operation of hydraulic structures.

[0003] For example, the "A circulating hydraulic curtain grouting device" with publication number: CN219992473U includes a stirring mechanism, which includes a stirring barrel. A feeding pipe is provided outside the stirring barrel, one end of the feeding pipe is connected to and communicated with the interior of the stirring barrel, a feeding pump is provided on the feeding pipe, and a discharge pipe is provided at the end of the feeding pipe away from the stirring mechanism. A disassembly mechanism is provided at the connection between the discharge pipe and the feeding pipe, and the discharge pipe can be detachably installed on the feeding pipe through the disassembly mechanism.

[0004] During the use of the existing circulating curtain grouting device, the prefabricated slurry needs to stay in the storage box for a long time waiting for transportation. The slurry has poor fluidity in the storage box and is prone to solidification. The mixing effect with the withdrawn slurry is poor, which affects the slurry state and transportation of the curtain grouting. Utility Model Content
