Description

Technical Field

[0001] The utility model relates to the technical field of catheter grouting joints, in particular to a small catheter grouting quick joint. Background Art

[0002] Advance small-duct grouting is a method of injecting grout into the surrounding rock obliquely above or near the face before excavation, in order to consolidate the soft and broken surrounding rock on the cave roof in front of the face, improve the condition of the surrounding rock, ensure the safety of face excavation, and ensure the stability of the face.

[0003] In the construction of advanced small-duct pressure grouting, the duct body is mostly connected by welding grouting valve.

This method makes the cost higher and it is easy to damage the pipe during the welding process, resulting in significantly lower practicality. For this reason, we provide a small-duct grouting quick connector to solve the above problems. Utility Model Content
