Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe piles, in particular to a high-strength concrete pipe pile. Background Art

[0002] The application document with publication number CN216865118U discloses a high-strength concrete pipe pile, comprising a pipe pile 1 and a pipe pile 2, wherein the pipe pile 2 is arranged at the top of the pipe pile 1, and a connecting device is arranged on the surface of the pipe pile 2, wherein the connecting device comprises a sleeve block 1 and a sleeve block 2, and a stabilizing device is arranged on the outer wall of the pipe pile 1, wherein the stabilizing device comprises a support rod and a stop block, and the stop block is arranged at one end of the support rod, and a plug-in assembly is arranged between the pipe pile 1 and the pipe pile 2. By arranging the connecting device, it is convenient to reinforce the connecting end of the pipe pile 1 and the pipe pile 2, to control the length of the pipe pile, to improve the compatibility of the equipment, to reduce the potential safety hazards during the construction process, and to improve the usability of the equipment. When the pipe piles are buried, the stabilizing device can be set to avoid the existing pipe piles from being easily tilted due to uneven force during burial, thereby affecting the load-bearing effect, thereby effectively improving the stability of the equipment.

[0018] A method for using a high-strength concrete pipe pile device according to any one of the above items comprises the following steps:

[0019] S1. When inserting the original pipe pile into the ground, according to the required insertion depth, first pull the two sets of pull rings. The two sets of pull rings pull the positioning rods in the A movable groove through the corresponding pull ropes to move and disengage from the positioning holes in the slide groove. While the positioning rods move, they also compress the A spring in the A movable groove. At this time, the arc sleeve can be slid on the slide groove through the slider, and the position of the arc sleeve on the original pipe pile is adjusted according to the indication of the scale. After completion, the two sets of pull rings are released. Under the rebound action of each A spring, the positioning rods are inserted into the positioning holes at the corresponding positions to fix the position of the arc sleeve. After the original pipe pile is inserted into the ground, the support plate on the arc sleeve fits on the ground to support the original pipe pile.

[0020] S2. When the pipe pile needs to be lengthened, the lifting rod first drives the clamping rod to compress the C spring in the C movable groove and disengage the second clamping groove in the B groove. Then, the support rod can be rotated to the horizontal position. At this time, the extended pipe pile can be positioned through the positioning block and placed on the top of the original pipe pile. In this process, the extended pipe pile will open the clamping block to compress the B spring in the B movable groove. Then, under the rebound action of the B spring, the clamping block is clamped in the first clamping groove on the extended pipe pile, realizing the connection between the original pipe pile and the extended pipe pile. Then, the support rod is rotated to the vertical direction to reset, and is fixed in the second clamping groove by the clamping rod. The support rod supports the four sides of the extended pipe pile, completing the installation of the extended pipe pile, that is, completing the lengthening of the pipe pile.

[0021] S3. When the parts on the arc sleeve are damaged and need to be replaced, turn the screws in the C groove. After the screws are separated from the connecting block, the two sets of arc sleeves can be separated for repair and replacement.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The high-strength concrete pipe pile can support the original pipe pile on all sides after it is inserted into the ground through the coordinated use of the slide groove, the arc sleeve, the positioning mechanism, the slider and the support plate to avoid tilting. At the same time, when adjusting the insertion depth according to the need, the arc sleeve can be quickly slid to adjust the position. This is simple and convenient, and solves the problem that the stabilizing devices on some existing devices need to be adjusted one by one during use. This method is not only time-consuming and labor-intensive, but also requires observing the position of each adjustment to keep it on the same horizontal plane, causing cumbersome use. It improves the flexibility of the pipe pile and enhances the practicality of the pipe pile.

[0024] (2) The high-strength concrete pipe pile, through the coordinated use of the connecting mechanism, the supporting mechanism and the positioning block, can not only connect the original pipe pile and the extended pipe pile through the connecting mechanism, but also lock the relative vertical position between the original pipe pile and the extended pipe pile under the action of the supporting mechanism, thereby ensuring the stability of the connection between the original pipe pile and the extended pipe pile. This solves the problem that when some existing devices extend the pipe pile, the connection between the extended pipe pile and the original pipe pile is simple, and the two are prone to relative bending during use, resulting in a decrease in the stability of the pipe pile. This improves the stability of the pipe pile and is conducive to the promotion and use of the pipe pile.

[0025] (3) The high-strength concrete pipe pile can realize disassembly and assembly by using the arc sleeve and the bolt assembly in combination. When the parts on the pipe pile are damaged during long-term use, they can be easily disassembled for repair, thus avoiding the high cost of damage caused by fixed connection, extending the service life of the pipe pile and ensuring the use effect of the pipe pile.

[0046] A method for using a high-strength concrete pipe pile device according to any one of the above items comprises the following steps:

[0047] When the original pipe pile 1 is inserted into the ground, the two sets of pull rings 505 are pulled first according to the required insertion depth. The two sets of pull rings 505 pull the positioning rods 502 in the A movable groove 501 through the corresponding pull ropes 504 to move and disengage from the positioning holes 506 in the slide groove 3. When the positioning rods 502 move, the A spring 503 in the A movable groove 501 is compressed. At this time, the arc sleeve 4 can be slid on the slide groove 3 through the slider 9, and the position of the arc sleeve 4 on the original pipe pile 1 is adjusted according to the indication of the scale 12. After completion, the two sets of pull rings 505 are released. Under the rebound action of each A spring 503, the positioning rods 502 are inserted into the positioning holes 506 at the corresponding positions to fix the position of the arc sleeve 4. After the original pipe pile 1 is inserted into the ground, the support plate 10 on the arc sleeve 4 is in contact with the ground to support the original pipe pile 1.

When the cam 702 is in the upright position, the locking block 603 is engaged with the locking spring 604 in the movable groove 602 of B, so that the cam 603 is engaged with the locking spring 604 in the movable groove 602 of B. When the cam 702 is in the upright position, the locking block 603 is engaged with the locking spring 604 in the movable groove 602 of B, so that the cam 603 is engaged with the locking spring 604 in the movable groove 602 of B.

[0049] S3. When parts on the arc sleeve 4 are damaged and need to be replaced, the screw 803 in the C groove 801 is rotated. After the screw 803 is separated from the connecting block 802, the two sets of arc sleeves 4 can be separated for repair and replacement.

[0050] When the pile is inserted into the ground, the two sets of pull rings 505 are pulled first according to the required insertion depth. The two sets of pull rings 505 pull the positioning rods 502 in the A movable groove 501 through the corresponding pull ropes 504 to move and disengage the positioning holes 506 in the slide groove 3. When the positioning rods 502 move, they also compress the A spring 503 in the A movable groove 501.

After completion, the two sets of pull rings 505 are released. Under the rebound action of each A spring 503, the positioning rods 502 are inserted into the positioning holes 506 in the corresponding positions to fix the position of the arc sleeve 4. After the original pile 1 is inserted into the ground, the support plate 10 on the arc sleeve 4 is in contact with the ground to support the original pile 1. When the pile needs to be lengthened, the upper lifting rod 705 drives the clamping rod 706 to compress the C spring in the C movable groove 703. The spring 704 disengages from the second slot in the B groove 701, and then the support rod 702 can be rotated to the horizontal position. At this time, the extended pipe pile 2 can be positioned through the positioning block 11 and placed on the top of the original pipe pile 1. In this process, the extended pipe pile 2 will stretch the block 603 to compress the B spring 604 in the B movable groove 602. Then, under the rebound action of the B spring 604, the block 603 is stuck in the first slot on the extended pipe pile 2, realizing the connection between the original pipe pile 1 and the extended pipe pile 2. Then, the support rod 702 is rotated to the vertical direction to reset and is fixed in the second slot by the block 706. The support rod 702 supports the extended pipe pile 2 on all sides, completing the installation of the extended pipe pile 2, that is, completing the lengthening of the pipe pile. When the parts on the arc sleeve 4 are damaged and need to be replaced, rotate the screw 803 in the C groove 801. After the screw 803 disengages from the connecting block 802, the two groups of arc sleeves 4 can be separated for maintenance and replacement.
