[0020] The working principle of the above technical solution is as follows: when in use, the user first moves the power vehicle 1 to the working position, inserts the feed bellows 5 into the concrete storage device, and then starts the mud pump 4. After the mud pump 4 is started, the cement is transported to the branch pipe 7, and enters the corrugated hose 9 through the branch pipe 7, and is introduced into the foundation pit through the grouting pipe 12. At this time, the sealed servo motor 17 rotates, and the auger rotating rod 20 is driven to rotate through the transmission steel cable 19, and an extrusion effect is applied to the cement, so that the cement can increase a certain pressure with the oblique mouth of the grouting pipe 12, which is convenient for grouting. Then, while grouting, the branch plate 13 is rotated. The sealing cone 15 covers the top of the foundation pit, and the air pump 6 is started to deliver air through the air hose 10, and the air enters the air head 14 through the annular pipe 16, and enters the support plate 13 and the inside of the foundation pit through the air head 14. At this time, the foundation pit and the grouting operation position are pressurized, so that the air pressure is applied to the foundation pit and the grouting position, and the slurry is pressurized to flow in the gap of the foundation pit, which improves the efficiency of the slurry in forming slurry veins, so that the slurry can quickly reach the position to form a composite foundation pit, increase the force, and the overall solution is convenient and simple to operate. One device can improve the operation, improve the operation efficiency, and reduce the workload.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the support plate 8 is fixedly installed on the top of the power vehicle 1 , the air pump 6 is fixedly installed on the top of the power vehicle 1 , and the air delivery head 14 is located on the inner side of the sealing cone 15 .

[0024] By setting the vibration motor 21, after the vibration motor 21 is started, the vibration force is transmitted to the grouting pipe 12 through the booster spring 22, so that the grouting pipe 12 generates a certain vibration conduction during operation, so that the bubbles inside the slurry can be discharged in advance, and the grouting effect of the slurry is balanced. In addition, the long dimensions of the grouting pipe 12 and the vibration shell 11 can penetrate deep into the foundation pit, and are gradually raised after the slurry veins are formed by pressurization, so that the slurry in the foundation pit forms a certain vibration to remove bubbles to achieve the purpose of compaction, thereby improving the efficiency of the operation and being simple to operate.

[0028] The auger rotating rod 20 forms a driving force for the slurry inside the grouting pipe 12, so as to facilitate the balanced flow rate of the slurry pushed by the grouting pipe 12, reduce the air cavity, and improve the transportation efficiency.

[0029] In another embodiment, Figure 1-Figure 3 As shown, a battery is arranged inside the distribution box 2.

[0030] The output end of the distribution box 2 is electrically connected to the input end of the mud pump 4, the air pump 6 and the sealed servo motor 17 through a wire, so that the distribution box 2 supplies power to the electrical appliances through the battery, thereby increasing the use effect of powering the structure and starting and stopping.
