Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a limiting structure of a pile hole grouting pipe. Background Art

[0002] Grouting pipe is a hollow long round steel. With the development of society, the application scope of grouting pipe is becoming more and more extensive, from construction engineering to civil engineering, and then to mining engineering.

[0003] In Chinese utility model CN217998220U, "a foundation pit sealing grouting pipe" is proposed. The grouting pipe adopts a double-layer casing with an inner tube and an outer tube, which can meet the needs of double-liquid slurry sealing. When moving downward, the grouting pipe pushes the movable cone sleeve to pierce the sandbag. After passing through the sandbag, the movable cone head falls and extends out of the front end of the grouting pipe by relying on the grouting pressure or its own gravity. The front end of the grouting pipe is open, so that the double-liquid slurry can be injected into the formation through the grouting pipe. However, the current installation structure of the pile hole grouting pipe is directly welded to the steel cage by welding. When it is used, it needs to be violently removed, which is easy to cause damage to the grouting pipe. Therefore, the existing technology has the problem that the grouting pipe cannot be flexibly installed and needs to be welded to the steel cage by welding. When it is used, it needs to be violently removed, which is easy to cause damage to the grouting pipe. Utility Model Content
