[0042] The sealing gasket 7 seals the first grouting port 22, and in use, the mud made of rubber material is ejected from the first grouting port 22, and in the process, the sealing member 32 reduces the probability of clogging of the first grouting port 22 by the silt.
[0043] In order to improve the stability of the device, the diameter of the limiting rod 5 gradually decreases from top to bottom. The gradually decreasing diameter of the limiting rod 5 from top to bottom reduces the probability of movement of the second gear 43, thereby improving the stability of the device.
[0044] In order to reduce the working difficulty of the staff, the through hole 8 is throughly provided on the side wall of the support frame 4. The through hole 8 reduces the difficulty of the staff in connecting the connecting pipe of the grouting equipment with the connecting port 21, thereby reducing the working difficulty of the staff.
