Description

Technical Field

[0001] This invention relates to the field of high-pressure jet grouting pile technology, specifically to a high-pressure jet grouting pile water-stop curtain construction device. Background Technology

[0002] A water-stop curtain is a commonly used water-stopping measure in underground engineering to prevent the seepage and flow of groundwater. It is typically achieved by forming a continuous, dense, waterproof barrier within the soil or rock.

[0003] The choice of materials for water-stop curtains usually depends on the specific engineering conditions and requirements. Commonly used materials include cement grout, polymer grout, and bentonite. These materials have high density and impermeability, effectively blocking the seepage of groundwater and ensuring the safety and stability of underground projects.

[0004] Water-stop curtains are widely used in underground engineering, including tunnel engineering, underground parking garage construction, water conservancy projects, subway stations, and underground pipelines. By adopting appropriate construction methods and materials, the seepage resistance of underground projects can be ensured, improving the reliability and durability of the projects.

[0005] High-pressure jet grouting is a commonly used foundation treatment technology to reinforce soil or rock layers to improve the bearing capacity and stability of the foundation. It involves injecting jetting material into the ground using a high-pressure jetting method to form piles, thereby strengthening and reinforcing the foundation.

[0006] The existing high-pressure jet grouting piles and grout pipe connections can achieve water-stopping effects by injecting grout material into the underground borehole at the same time to form a grouting column or grouting curtain. However, the high-pressure jet grouting operation will cause the grout pipe to move up and down, causing friction between the grout pipe and the ground, which will damage the surface of the grout pipe. This makes it easy for the grout to be ejected from the grout pipe, resulting in grout waste. Summary of the Invention

By holding the front end of the metal connecting ring 1461 and pushing the rear end of the metal connecting ring 1461, the metal connecting ring 1461 can slide on the surface of the slurry support roller 13. At the same time, the sliding connecting block 1464 slides on the upper inner wall surface of the slurry support roller 13.

[0030] The sliding assembly 12 includes a sliding connecting sleeve 121, a metal slider 122, a limiting threaded rod 123, and a second metal slide rod 124.

[0031] The support frame 11 includes a metal support frame 111, a metal slide bar 112, a sliding connecting block 113, and a limiting connecting block 114. The sliding connecting block 113 is located at the lower end of the support frame 11 and is fixedly connected to the bottom surface of the metal support frame 111.

The sliding connecting sleeve 121 is movably connected to the inner wall surface of the connecting metal plate 141. The sliding connecting sleeve 121 drives the adjusting device 14 to move up and down, and the adjusting device 14 drives the slurry support roller 13 to move up and down, thereby adjusting the position of the slurry support roller 13. When the metal slider 122 reaches the set position... After positioning, grasp the right end of the connecting metal plate 141 and pull it downwards. The connecting metal plate 141 drives the sliding connector 15 to rotate. The metal support frame 111 is fixedly connected to the back of the limiting connecting block 114. There are two limiting connecting blocks 114, which are distributed vertically. The lower support frame 11 is threaded to the top surface of the drive motor 2. The limiting connecting block 114 is movably connected to the surface of the lifting threaded rod 5. The support frame 11 is movably connected to the top surface of the support metal plate 3. The support metal plate 3 is movably connected to the surface of the sliding connecting block 113. The drive motor 2 drives the lifting threaded rod 5 to rotate. The lifting threaded rod 5 can rotate on the inner wall surface of the limiting connecting block 114, allowing the lifting threaded rod 5 to drive the sliding connecting sleeve 121 to move up and down.

[0032] In use, hold the lower end of the metal support frame 111 and push it back and forth. The metal support frame 111 drives the sliding connecting block 113 to move back and forth, allowing the sliding connecting block 113 to move back and forth on the inner surface of the supporting metal plate 3. This allows adjustment of the position of the sliding metal support frame 111. When the metal support frame 111 moves back and forth on the top surface of the supporting metal plate 3, it drives the drive motor 2, sliding assembly 12, adjusting device 14, and lifting threaded rod 5 to move back and forth. After reaching the appropriate position, hold the rear end of the sliding connecting block 1464 and push it forward. The sliding connecting block 1464 then inserts into the metal connecting ring 1461. When the sliding connecting block 1464 moves forward, it drives the fixed threaded rod 1462 to move forward. The fixed threaded rod 1462 can slide on the upper inner wall surface of the metal connecting ring 1461, so that the back of the sliding connecting block 1464 and the back of the metal connecting ring 1461 are on the same horizontal plane. Then, hold the rectangular plate and push it downward. The rectangular plate can slide downward on the upper inner wall surface of the metal connecting ring 1461, so that the rectangular plate can slide on the threaded end surface of the fixed threaded rod 1462. Then, hold the surface of the hexagonal nut 1463 and rotate the hexagonal nut 1463. The hexagonal nut 1463 rotates on the threaded end surface of the fixed threaded rod 1462. Make sure the hexagonal nut 1463 can thread-fix the metal connecting ring 1461 and the sliding connecting block 1464. Then, hold the front end of the metal connecting ring 1461 and push the rear end of the metal connecting ring 1461 so that the metal connecting ring 1461 can slide on the surface of the slurry support roller 13. At the same time, the sliding connecting block 1464 slides on the upper inner wall surface of the slurry support roller 13. Then, hold the surface of the metal connecting ring 1461 and push the metal connecting ring 1461 to move it backward so that the metal connecting ring 1461 is inserted into the inner wall surface of the left end of the connecting metal plate 141. Then, hold the upper end of the limiting metal ring 142 and push the limiting metal ring 142 to rotate. The limiting metal ring 142 rotates clockwise around the metal pin 143, so that the limiting metal... The left side surface of the metal ring 142 and the threaded bolt 144 are movably connected. Then, grasp the hexagonal end of the threaded bolt 144 and push it downwards, allowing it to insert into the connection between the limiting metal ring 142 and the connecting metal plate 141. Next, grasp the surface of the hexagonal nut 145 and rotate it. The hexagonal nut 145 rotates on the threaded end surface of the threaded bolt 144. The rotation of both the hexagonal nut 145 and the threaded bolt 144 secures the connecting metal plate 141 and the limiting metal ring 142 with threads. When the connecting metal plate 141 and the limiting metal ring 142 are threadedly fixed, they clamp and fix the position of the metal connecting ring 1461.Next, grasp the surface of the threaded bolt 1465 to secure the sliding connecting block 1464 and the slurry support roller 13 with threads. This limits and fixes the position of the slurry support roller 13. Start the drive motor 2. The rotor of the drive motor 2 drives the lifting threaded rod 5 to rotate. The lifting threaded rod 5 can rotate on the inner wall surface of the limiting connecting block 114, causing the sliding connecting sleeve 121 to move up and down. The sliding connecting sleeve 121 drives the adjusting device 14 to move up and down, and the adjusting device 14 drives the slurry support roller 13 to move up and down. This allows adjustment of the position of the slurry support roller 13. When the metal slider 122 reaches the appropriate position, grasp the right end of the connecting metal plate 141 and pull it downwards. The connecting metal plate 141 drives the sliding connector 15 to rotate. Since the sliding connector 15 and the connecting metal plate 141 are movably connected, the sliding connector 15 can be parallel to the ground, allowing it to move on the threaded end surface of the limiting threaded rod 123. When the sliding connector 15 moves on the surface of the limiting threaded rod 123, the limiting threaded rod 123... 3. The metal slider 122 moves up and down, and moves up and down on the inner surface of the front section of the sliding connecting sleeve 121. At the same time, the metal slider 122 can slide up and down on the surface of the second metal slider 124, thereby adjusting the angle of the connecting metal plate 141. After the connecting metal plate 141 is at the optimal angle, the surface of the third hexagonal nut 16 is grasped and the third hexagonal nut 16 is rotated. The third hexagonal nut 16 is on the threaded end surface of the limiting threaded rod 123, so that the two third hexagonal nuts 16 can be movably connected to the left and right surfaces of the slurry support roller 13. The position of the metal slider 122 can be fixed and limited. By holding the left end of the grout pipe, the surface of the grout pipe is movably connected to the bottom surface of the left-end grout support roller 13 and the upper surface of the right-end grout support roller 13. This allows the left end of the grout pipe to be movably connected to the upper surface of the high-pressure jet grouting pile. When the high-pressure jet grouting pile is drilling, the drill rod inside the pile drives the grout pipe downwards, causing it to move downwards. Simultaneously, the grout support roller 13 limits the position of the grout pipe, preventing friction between the grout pipe and the ground and protecting the surface of the grout pipe.
