Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and more specifically to a foundation pit grouting device for a water conservancy project. Background Art

[0002] In the field of water conservancy project construction, grouting devices are often used to perform grouting treatment on damaged areas that have been constructed and on locations that are under construction but cannot be directly operated with mud.

[0003] In the grouting operation, the slurry is poured into the hopper of the equipment, and the equipment is started to grout the designated area with the help of the transmission pipe. However, during the slurry transmission process, due to gravity sedimentation, irregular operation time intervals, and insufficient pre-mixing, the slurry is prone to viscous sedimentation and cement sand and gravel combined to form material blocks, which will cause slurry blockage during the transmission operation, seriously affecting the normal grouting operation. It not only takes a lot of time to clean and repair, but also delays the construction progress and increases the construction cost. At the same time, the viscous sedimentation of the slurry and the material blocks will also make the grouting effect poor, affecting the quality and stability of the water conservancy project. For this reason, we propose a grouting device for the foundation pit of a water conservancy project. Utility Model Content
