Description

Technical Field

[0001] The utility model is set in the technical field of grouting equipment, in particular to a casing grouting funnel structure. Background Art

[0002] In the prior art, during the grouting operation, mud needs to be poured into the well. In the prior art, the use of a hose line for grouting will cause the solid phase matter in the mud to gradually accumulate after a long time of use, which can easily cause the pipeline to be blocked, and cause the pump to be blocked after starting the mud pump; because the grouting hose line cannot be effectively fixed, after the pump is blocked, the pipeline will be instantly released due to the sudden opening of the channel, which can easily cause the pipeline to fly out and cause an accident, and at the same time, the mud will be sprayed everywhere.

[0003] Generally, a grouting funnel is used to assist in grouting. However, if the grouting funnel is directly inserted into the casing, the casing may be easily tilted due to the difference in diameter. After the grouting funnel is inserted into the casing, the casing will be sealed. If the material is discharged too quickly, the grouting funnel may still be easily blocked, making it difficult to discharge the internal air. Utility Model Content

[0004] The purpose of the utility model is to provide a casing grouting funnel structure, which is mainly used for auxiliary grouting and can avoid tilting during use. At the same time, it can also achieve the purpose of exhaust during the grouting process.
