This helps to keep the extrusion component 41 away from the opening of the grouting pipe, which can correspondingly reduce the obstruction of the inner wall of the tunnel and the structure inside the tunnel to the operation of the extrusion component 41, thereby facilitating operation and use.

[0029] In this embodiment, the main pipe includes a slurry inlet pipe 12 and a threaded pipe 13, the valve 20 is arranged on the slurry inlet pipe 12, the external thread section is arranged on the threaded pipe 13, and the slurry inlet pipe 12 and the threaded pipe 13 are detachably connected, which is convenient for processing, manufacturing and maintenance, and helps to reduce manufacturing costs and use costs.

[0030] In this embodiment, the sealing sleeve 30 is in the form of a long tube and is sleeved on the tail section of the main pipe, which can increase the sealing surface and help improve the sealing effect. In this embodiment, the tail end of the sealing sleeve 30 can be fixed on the main pipe, or a boss is provided at the tail end of the main pipe to abut against the tail end of the sealing sleeve 30, so that when the head end of the sealing sleeve 30 is squeezed, the sealing sleeve 30 can be expanded, which has a simple structure and is convenient for manufacturing and use. In other embodiments, the sealing sleeve 30 can also be selected from other suitable shapes and structures, and is not limited thereto.

[0031] In this embodiment, the valve 20 is detachably arranged on the main pipe, so that it is convenient to replace the valve 20 of different sizes and specifications according to needs, and it is also convenient to disassemble and repair.
