[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0042] See attached Figure 1-4 As shown, according to some embodiments of the present application, it includes: a centering device, characterized in that a plurality of guide ends arranged in a ring array are provided on the centering device, which are provided at one end of the first section of the pipe pile, so that the other pipe piles enter the interior of the first section of the pipe pile along the guide end of the centering device. In other words, by installing a detachable annular structure on the first section of the pipe pile and providing a guide end on the annular structure, the second section can enter the interior of the first section of the pipe pile along the guide end, thereby ensuring that the two sections of the pipe pile are concentric.

[0043] It should be noted that the centering device is a combined structure, including:

[0044] A first main body 1, which is an arc-shaped rod or plate structure, with a first connecting end 101 at one end and a second connecting end 102 at the other end;

[0045] A second body 2, wherein the second body 2 is an arc-shaped rod and plate structure, one end of which is provided with a third connecting end 201, and the other end of which is provided with a fourth connecting end 202;

[0046] Among them, the first connection end 101 and the third connection end 201 are annular structures, and through holes are provided on the first connection end 101 and the third connection end 201. By interlocking the first connection end 101 and the third connection end 201, the through holes of the two are aligned, and a hinge structure is formed through structures such as a pin shaft.

[0047] The second connection end 102 and the fourth connection end 202 are plate-like structures, and are provided with through holes;

[0048] The guide component 3 is a trapezoidal, triangular, or other structure that can play a guiding role. A wedge-shaped block is preferably used. The guide component 3 is arranged in a ring array and is respectively provided on the first body 1 and the second body 2. The guide component 3 is fixedly connected to the first body 1 and the second body 2.

[0049] The receiving component 4 is a structure that can connect the first connection end 101 and the third connection end 201 by means of a pin, a bolt, etc., so that the first connection end 101 and the third connection end 201 can rotate around the receiving component 4. The receiving component 4 passes through the first connection end 101 and the third connection end 201 respectively, and is rotatably connected to the first body 1 and the second body 2.

[0050] The locking component 5 passes through the second connecting end 102 and the fourth connecting end 202 respectively, thereby forming a ring structure between the first body 1 and the second body 2.

[0051] It should be further explained that the locking component 5 is a bolt-type or automatic locking structure, wherein when the locking component 5 is a bolt-on structure, it includes

[0052] A screw, one end of which passes through the second connection end 102 and the fourth connection end 202 respectively;

[0053] The nut is arranged on the screw rod far away from the fourth connection end 202 and is threadedly connected to the screw rod.

[0054] The screw is passed through the through holes of the second connection end 102 and the fourth connection end 202 in sequence and rotated by the nut, so that the distance between the second connection end 102 and the fourth connection end 202 is reduced to achieve a locking effect.

[0055] When the locking component 5 is an automatic locking structure, it includes:

[0056] The first sliding component 501 is a rod-shaped structure, one end of which passes through the second connecting end 102 and the fourth connecting end 202 respectively, and the other end of which is provided with a threaded hole;

[0057] The support member 502 is a ladder-shaped structure, and the support member 502 is symmetrically arranged on the second connection end 102, and is fixedly connected to the second connection end 102;

[0058] The driving component 503 is a stepping motor or a servo motor. The driving component 503 is arranged on the supporting component 502. The output end thereof penetrates the supporting component 502 and extends into the threaded hole. The output end thereof is threadedly connected to the first sliding component 501.

[0059] The second sliding component 504 is a block structure, and is symmetrically arranged with respect to the first sliding component 501 and is respectively provided on the supporting component 502, and is slidably connected with the supporting component 502;

[0060] The receiving member 505 is a rod-shaped structure, one end of which passes through the second sliding member 504 and the other end is fixedly connected to the first sliding member 501, wherein the receiving member 505 is provided with an external thread, and a double-layer nut 5051 is provided on the receiving member 505, and the double-layer nut 5051 is threadedly connected to the receiving member 505, and the second sliding member 504 is locked by the double-layer nut 5051, wherein the double-layer nut 5051 can be replaced with a self-locking structure, and the double-layer nut 5051 can also be not provided;

[0061] The baffle member 506 is disposed at one end of the first sliding member 501 passing through, and is slidably connected to the first sliding member 501 .

[0062] Wherein, the baffle component 506 includes:

[0063] A connecting body 5061, wherein the connecting body 5061 is fixedly connected to the first sliding component 501;

[0064] The arc rod 5062 is disposed at the end of the connecting body 5061 and is fixedly connected to the connecting body 5061 .

[0065] During use, by opening the driving component 503, the output end is rotated in the threaded hole. Since the first sliding component 501 is constrained by the receiving component 505 and the supporting component 502, it cannot rotate and can only move along the through holes of the second connecting end 102 and the fourth connecting end 202, so that the connecting body 5061 drives the arc rod 5062 to move, and then the arc rod 5062 contacts the fourth connecting end 202, thereby reducing the distance between the second connecting end 102 and the fourth connecting end 202, thereby achieving a locking effect. During this process, the second sliding component moves with the first sliding component 501.

[0066] In some embodiments of the present application, a method for improving the welding quality of pipe piles is disclosed, using the above disclosed device for improving the verticality control of pipe piles, comprising the following steps:

[0067] Step 1: Install the first section of the pipe pile at the preset position, and adjust the angle of the first section of the pipe pile by the theodolite so that the first section of the pipe pile is installed on the site at a preset angle;

[0068] Step 2: Install the centering device on the top of the first section of the pile;

[0069] Step 3: After the second section of the pile is lifted by the lifting device, the bottom of the second section of the pile is located above the centering device;

[0070] Step 4: Lower the second section of the pile through the lifting device and the centering device, so that the second section of the pile falls completely into the first section of the pile;

[0071] Step 5: Use the theodolite to further observe the angles of the two sections of pipe piles. When they are correct, proceed with welding. If there is an error, lift the second section of pipe pile again through the lifting device and repeat steps 3 and 4 until they are correct and then proceed with welding.

[0072] During the welding process in step 5, the first body 1 and the second body 2 are separated by loosening the locking device, and then the centering device is detached from the first section of the pipe pile, and then welding is performed.

[0073] During the specific implementation process,

[0074] First, use the total station to find the center point of the secondary pile position, draw it with a line, build pile guards, drive the first pipe pile, and then install the verticality device to make the two ends of the pipe pile fit tightly together, facilitating subsequent welding and ensuring verticality.

[0075] Pipe piles are made in the pipe pile prefabrication yard and transported to the site after maintenance. The first section of the pipe pile is first driven into position, and then the verticality device is fixed at the clamp position of the first section of the pipe pile. Then, the two theodolites are set at an angle of 90° to meet the verticality. The centering device is installed on the first section of the pipe pile on the ground and fixed firmly. Because the end of the pipe pile is equipped with a steel plate hoop, it can prevent the centering device from falling off, and then wait for the second section of the pipe pile to be hoisted; the second section of the pipe pile is visually higher than the top of the device; the second section of the pipe pile is hoisted and prepared to be lowered into the device; the second section of the pipe pile is lowered to the top of the first section and completely falls on the first section; two theodolites are used to observe the verticality at 90°, and the wire rope can be lowered within the allowable range. After removing the centering device, use the second welding to start welding the pipe piles.

[0076] The method comprises the following steps: manufacturing a quick centering device for pipe piles, using a verticality device to quickly center the upper and lower pipe piles during each construction of the pile-slab bridge pipe piles, using the device's high-strength bolts to adjust the tightness and fix the position of the lower pipe pile, using two theodolites to meet the verticality of the pipe piles, using the verticality device to slide down to the lower pipe pile, welding the upper and lower pipe piles after the piles are dropped, applying anti-rust paint after cooling, and then entering the next cycle; the patented principle of the present invention is to install a centering device on the first pipe pile section passing through the ground, fix it firmly, because the end of the pipe pile is equipped with a steel plate hoop, which can prevent the centering device from falling off, and then wait for the second pipe pile section to be hoisted; hoist the second pipe pile section to be visually higher than the top of the device; hoist the second pipe pile section to prepare for lowering into the device; lower the second pipe pile section to the top of the first section and completely fall on the first section; use two theodolites to observe the verticality, and the steel wire rope can be dropped within the allowable range, and the pipe pile welding can be started after the centering device is removed.

[0077] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0078] During the construction process, the centering accuracy and construction safety are guaranteed, the construction and installation time is shortened, the work efficiency is greatly improved, and an efficient and convenient solution is provided for pile-slab bridges. It also protects the pile head from colliding back and forth, does not affect the verticality of the bottom pile, greatly guarantees the technical quality of the pile, and improves the appearance and control quality of the pile.
