Description

Technical Field

[0001] The utility model relates to the technical field of dam body consolidation grouting, in particular to a diversion pipe for dam body consolidation grouting. Background Art

[0002] Dam body consolidation grouting construction is a commonly used technology in the construction of water conservancy projects. By injecting grouting materials, the stability and density of the dam body can be increased, and the anti-seepage performance of the dam body can be improved. During construction, the configured slurry is poured into the grouting pump and injected into the interior of the dam body through the grouting pipe and the diversion pipe. The existing diversion pipe for dam body consolidation grouting has certain disadvantages when used. Due to the different depths required for grouting, the diversion pipe cannot be adjusted in length according to actual conditions and needs to be extended. The simple snap-on connection is prone to loosening, causing the slurry to seep out, resulting in a waste of resources. When the slurry enters the interior of the dam body, it will squeeze the soil in the holes, making it impossible for the soil to be discharged. For this reason, we propose a diversion pipe for dam body consolidation grouting. Utility Model Content
