Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction equipment, in particular to a water conservancy engineering grouting equipment. Background Art

[0002] Grouting in hydraulic engineering is an important engineering measure used to improve the anti-seepage capacity and overall stability of the foundation. The main purpose of grouting is to fill the cracks and pores in the rock and soil to prevent water penetration and improve the integrity, strength and stiffness of the rock and soil. In hydraulic structures such as gates, dams, dikes and other water retaining structures, an effective foundation anti-seepage curtain can be constructed through grouting. The commonly used grouting equipment is a cement grouting machine. The existing cement grouting machine pressurizes and injects the evenly stirred cement slurry into the cracks through the Jiaolong spiral in the top hopper. When the cement slurry is fed into the cement slurry hopper, there is no diversion design on the top, so a large amount of cement slurry will directly fall and impact the Jiaolong spiral entering the feed hopper, which will cause the cement slurry to be splashed out of the cement slurry hopper, affecting the grouting construction of on-site construction personnel. In order to solve this problem, a new type of grouting equipment for hydraulic engineering is needed. Utility Model Content
