A movable rail 14 is provided at one end of the grouting device 3 and the plug 2 near the grouting sleeve 1. A clamping seat 18 is symmetrically provided at the top of the movable rail 14. In use, the clamping seat 18 is used to connect the grouting device 3 to the grouting pipe 5, and the plug 2 to the grout outlet pipe 4. The other end of the grouting device 3 is connected to the grouting machine, which can prevent grout from seeping out of the grouting pipe 5. The plug 2 is used to observe the filling rate of grout in the grouting sleeve 1.
[0023] For example, a bidirectional lead screw 15 is installed inside the movable rail 14, and lead nuts 17 are symmetrically arranged on both sides inside the movable rail 14. The lead nuts 17 are all engaged with the bidirectional lead screw 15, and the bottom of the clamping seat 18 is connected to the lead nuts 17 by bolts. A rotating handle 16 is installed at one end of the movable rail 14, and the output end of the rotating handle 16 is connected to the bidirectional lead screw 15 through a rotating shaft. When the rotating handle 16 is rotated, it will drive the bidirectional lead screw 15 to rotate, so that the two lead nuts 17 can move closer to each other, and drive the clamping seat 18 to move closer synchronously, and finally firmly clamp the outer wall of the grouting pipe 4 or the grouting pipe 5. This clamping method based on lead screw transmission is not only faster than the traditional clamp connection method, which can effectively shorten the construction time and improve the construction efficiency, but also provides a strong clamping force to ensure that the connection between the grouting device 3 and the sealing device 2 and the grouting pipe 4 and the grouting pipe 5 is stable.

The coolant flows out from the other end of the water-cooling channel 11 and returns to the coolant tank 7. The coolant circulates in the water-cooling channel 11, which can reduce the temperature of the concrete in the first sleeve 8 and the second sleeve 20 and prevent the concrete in the first sleeve 8 and the second sleeve 20 from solidifying.
[0025] For example, the grouting device 3 comprises a first mounting base 6 and a first sleeve 8 connected integrally, and a cooling liquid tank 7 is mounted in the first mounting base 6, a water cooling channel 11 is formed in the inside of the first sleeve 8, and a threaded connecting pipe 10 is arranged at the end of the first sleeve 8 away from the movable rail 14, a ball valve 9 is mounted at the end of the inside of the first sleeve 8 close to the threaded connecting pipe 10, and the flow of grouting can be controlled by adjusting the ball valve 9, and when the grouting is close to full, the flow of grouting is reduced, so that the grouting effect is better.
