Description

Technical Field

[0001] The invention relates to the technical field of roadbed construction, in particular to railway roadbed grouting reinforcement construction equipment. Background Art

[0002] The high frequency of use and load-bearing of railway lines can easily lead to damage to the railway lines. For example, the load of heavy-loaded trains with large axle weights and high density can cause track subsidence, mud oozing and other defects, seriously affecting driving safety. The main way to deal with track subsidence, mud oozing and other defects is to reinforce the existing railway subgrade with grouting.

[0003] Existing roadbed grouting construction requires drilling holes in the roadbed first, and then grouting operations are performed into the roadbed through the holes. The drilling construction is performed by rotating a spiral drill rod into the roadbed. Some equipment sets the drill rod to a hollow structure, and grouting operations are performed through the inside of the drill rod. Since the inside of the drill rod is hollow and the roadbed base material will enter the inside of the drill rod when drilling, causing blockage inside the drill rod. At the same time, when the grouting liquid passes through the inside of the drill rod, the grouting liquid will also adhere to the inner wall of the drill rod. The solidification of the grouting liquid will cause blockage inside the drill rod, thereby affecting subsequent grouting operations. Summary of the invention

[0036] The above embodiment provides a railway roadbed grouting reinforcement construction equipment, wherein, in the initial state, the rope unit 390 is in a closed state and does not restrict the vertical movement of the locking portion 370, the locking portion 370 is stuck on the fastening flange 360 ​​and the lower blocking piece 341 blocks the lower port of the hollow spiral grouting drill rod 340, and the drilling drive assembly 380 starts to work, the drilling drive assembly 380 drives the lifting support plate 330 to move downward and the hollow spiral grouting drill rod 340 to rotate, and the hollow spiral grouting drill rod 340 is screwed into the railway roadbed; because the locking portion 370 is always stuck on the fastening flange 360, Therefore, the blocking top rod portion 342 and the lower blocking piece 341 move downward with the lower blocking piece 341, so that the lower blocking piece 341 is always at the lower port of the hollow spiral grouting drill rod 340 and prevents the roadbed soil from entering the hollow spiral grouting drill rod 340, thereby preventing the hollow spiral grouting drill rod 340 from being blocked by entering the soil. After the drilling is completed, the rope unit 390 starts to work and the rope unit 390 pulls the locking portion 370 upward. The locking portion 370 is subjected to the upward pulling force and is separated from the fastening flange 360. Therefore, the locking portion 370 drives the lower blocking piece 341 and the blocking top rod under the pulling of the rope unit 390. When the lower plugging piece 341 moves to the inside of the grouting rotating end sleeve 350 and is located on the upper side of the connection between the grouting rotating end sleeve 350 and the end of the grouting pipe 500, the rope unit 390 stops working and remains in a stable state. At this time, the grouting pump 510 starts working and the grouting pump 510 introduces the grouting liquid inside the slurry storage tank 200 into the hollow spiral grouting drill rod 340 through the grouting pipe 500, and the grouting liquid is injected into the bottom of the roadbed through the lower port of the hollow spiral grouting drill rod 340. After the grouting is completed, the drilling drive assembly 380 starts working and drives The movable hollow spiral grouting drill rod 340 moves upward, and the slurry guiding rotating end sleeve 350 moves with the hollow spiral grouting drill rod 340 and the lower sealing piece 341 is gradually located inside the hollow spiral grouting drill rod 340, so that the hollow spiral grouting drill rod 340 and the lower sealing piece 341 move relatively, and the lower sealing piece 341 can push the grouting liquid on the inner wall of the hollow spiral grouting drill rod 340 through the lower port of the hollow spiral grouting drill rod 340, thereby effectively cleaning the grouting liquid on the inner wall of the hollow spiral grouting drill rod 340 and preventing the grouting liquid from solidifying on the inner wall of the hollow spiral grouting drill rod 340 and affecting the subsequent grouting construction.

[0037] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
