The first driving member 6-1 includes a motor and a driving rod. A synchronous wheel 4 is also provided at the end of the driving rod. When the motor is started, the synchronous wheel 4 is driven, and the delivery pipe 3242 rotates to realize the rotation between the through hole 3243 passing through the first channel and the second channel.

The control valve is controlled by the controller, and the monitoring information of the sensor is wirelessly transmitted to the controller. The controller controls the start of the control valve according to the monitoring information to realize the grouting process.

[0034] Since the properties of different soil layers are different, grouting liquid suitable for the properties is injected to better achieve the reinforcement of the soil layer. Therefore, when the grouting liquid is converted, the slurry remaining in the grouting inner pipe 32 from the previous time needs to be cleaned, so a pipe cleaning component is provided on the transverse pipe 322. When cleaning is needed, the pipe cleaning part 7 is started. The pipe cleaning part 7 is used to clean the residue in the grouting inner pipe 32. The management and cleaning part includes a water suction port 71 and a water inlet 72 provided on the transverse pipe 322, and a lifting plate 73 provided at the end of the transverse pipe 322. The water suction port 71 is connected to the water pump through a water suction pipe, and the water inlet 72 is connected to the liquid storage chamber 22 through a water pipe. A screw rod 741 is provided on the lifting plate 73, and a symmetrical transmission group 74 is formed on the upper end of the screw rod 741, forming two groups of transmission groups 74.

The driving belt 5 and the second driving member 6-2 are started, the screw rod 741 rotates, and the transmission belt 5 synchronously drives the other screw rod 741 to rotate, so as to realize the relative movement of the lifting plate 73 along the length direction of the screw rod 741; for example, the through hole 3243 is connected to the first channel, and the slurry flows out of the slurry outlet 312 through the first channel to reinforce the soil layer. When switching to the next soil layer, the through hole 3243 rotates to connect the second channel, and the slurry flows out of the slurry outlet 312 through the second channel to reinforce the next soil layer. At the same time, the first channel is cleaned by the pipe cleaning member 7. The two ports on the first channel are blocked by the lifting plate 73 to form a closed space. The cleaning liquid in the liquid storage chamber 22 enters the first channel through the water inlet 72, and is pumped out by the water pump, and the residue in the pipeline is pumped out together with the cleaning liquid to prevent the residue from accumulating and causing the pipeline to be blocked, affecting the efficiency of grouting, and realizing the grouting inner tube 32 to switch grouting reinforcement between the first channel and the second channel in turn;

[0035] The lifting assembly 8 includes a base 81 and a lifting mechanism 82 that drives the base 81 to move synchronously in the grouting appearance. The first driving member 6-1 and the second driving member 6-2 are arranged on the base 81. The delivery pipe 3242 of the grouting inner tube 32 is also fixedly arranged on the base 81. The connecting rod 3231 in the grouting inner tube 32 passes through the base 81. A first gear is provided on the connecting rod 3231. A second gear is provided on the base 81. The second gear is engaged with the first gear. The rotation of the second gear realizes that the first gear drives the entire grouting inner tube 32 to rotate. The lifting mechanism 82 is hydraulically driven or lifting driven. The grouting inner tube 32 is moved up and down to realize grouting reinforcement of different soil layers. Since the blocking plate 314 is provided on the grouting outer tube 31, when the grouting inner tube 32 leaves the slurry outlet 312, it is necessary to rotate the position of the grouting inner tube 32 to move to the next slurry outlet 312 position, and then align the transverse tube 322 with the slide rail 313 on the side of the slurry outlet 312, and align the transverse tube 322 with the slurry outlet 312; during grouting, since the transverse tube 322 is aligned with the slurry outlet 312 and the end of the transverse tube 322 is stuck with the slide rail 313, the gear rotates to realize that the grouting inner tube 32 drives the grouting outer tube 31 to rotate.

[0036] Working principle: The grouting outer tube 31 is pressed into or drilled into the soil layer. The sensors on the grouting outer tube 31 monitor the properties of the soil layer. When the values ​​detected by the sensors at the upper and lower ends are different from those detected by the sensor in the middle, it indicates that the grouting outer tube 31 is pressed into the correct position. The monitoring information of the sensor is transmitted to the controller. The controller manually configures materials of different proportions for the slurry making chamber 21 to stir and form the required slurry according to the monitoring information. The lifting component 8 moves the grouting inner tube 32 and moves the grouting inner tube 32 to the corresponding position. The transverse tube 322 of the grouting inner tube 32 presses the sealing plate 314 downward. The end of the transverse tube 322 is aligned with the slurry outlet 312 and is stuck in the slide rail 313 to prevent the transverse tube 322 from rotating. The first channel is for grouting. Channel, the second channel is not in use, the gear on the lifting assembly 8 rotates, and the transverse tube 322 drives the grouting outer tube 31 to rotate and grouting. When the grouting is completed, the next grouting is carried out, and the grouting inner tube 32 changes the grouting position through the lifting mechanism 82. The grouting inner tube 32 is converted into grouting of the second channel through the conversion of the through hole 3243. The lifting plates 73 of the two transverse tube 322 ports on the second channel are opened, and the first channel is used for pipeline cleaning. The lifting plates 73 of the two transverse tube 322 ports of the first channel seal the two ports, and clean them through the water inlet 72 and the water pumping port 71 to prepare for the next use. The cycle is repeated. When the soil layers are reinforced, the grouting outer tube 31 and the grouting inner tube 32 are taken out.
