[0029] In some embodiments, the connecting end of the shotcrete equipment 2 is movably fitted with a locking nut 10 to facilitate threaded connection with the interface body 1.

[0030] In some embodiments, the connecting end of the shotcrete equipment 2 is provided with a limiting ring 11 corresponding to the locking nut 10. The limiting ring 11 is used to limit the position of the locking nut 10. At the same time, the sealing gasket 6 can be squeezed during installation to play a sealing role.

[0031] In some embodiments, the left end of the connecting part 7 is provided with a limiting block 12 corresponding to a set of limiting grooves 9. The limiting block 12 is used to limit the position of the port of the shotcrete pipe 3 when it is assembled.

[0032] In some embodiments, a set of tie rods 13 are hinged to the connecting end of the shotcrete pipe 3. Each tie rod 13 has a locking block 14 corresponding to the annular groove 8 at its front end, which facilitates quick connection with the interface body 1.
