Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation construction, in particular to a pipe pile planting auxiliary device and a construction method. Background Art

[0002] Pipe piles, a type of pile foundation, are an essential building material in industrial and construction. Based on concrete strength grade and wall thickness, they are categorized as prestressed concrete pipe piles (PC pipe piles), prestressed thin-walled concrete pipe piles (PTC pipe piles), and prestressed high-strength concrete pipe piles (PHC pipe piles). They offer high bearing capacity and ease of construction. As a prefabricated pile, pipe piles are widely used in industrial and civil construction, municipal administration, transportation, water conservancy, railways, and other fields.

[0003] There are three main methods for constructing prestressed concrete pipe piles: the soil-extruding hammer method, the static pressure method, and the non-soil-extruding pipe-while-drilling method and the mid-excavation method. Except for offshore platforms and port terminal projects, prefabricated pipe piles can reach lengths of up to 50 meters. For other land transportation applications, due to the minimum curvature radius of road bends, the length of a single pipe pile generally does not exceed 20 meters. In thick soft soils, the pile foundation is buried deep, necessitating pile splicing. Common methods for splicing piles include welding and mechanical splicing. Regardless of the splicing method, joint alignment is difficult and time-consuming. Misalignment also affects the verticality and bearing capacity of the pile. Furthermore, because the riverbed geology is primarily sandy and gravelly, equipment cannot be effectively positioned during the construction of the pipe pile protection trench. This results in the piles being squeezed by the gravel stratum, often causing displacement, which in turn affects construction quality. Therefore, in response to these current challenges, there is an urgent need to develop a pipe pile driving assistance device and construction method to overcome these shortcomings. Summary of the Invention

[0004] The object of the present invention is to provide a pipe pile planting auxiliary device and a construction method to solve the problems raised in the above background technology.

[0007] A pipe pile planting construction method, using the pipe pile planting auxiliary device described above, comprises the following steps:

[0008] Step 1: The slide rail is fixed to the ground, and the mounting base moves along the slide rail. When it reaches the designated position, the control component drives the control board to move downward. The control board cooperates with the fixing rod to drive the first piston to move inside the pressure pipe, driving the ground drill to drill into the ground, completing the fixing of the mounting base.

[0009] Step 2: The power source drives the annular support seat to rotate so that the support shell and the ground are on the same slope, and then the telescopic member drives the support shell to rotate around the connection end with the support column, thereby completing the leveling of the support shell;

[0010] Step 3: The lower section of the pile passes through the support shell and the installation base and is drilled into the ground;

[0011] Step 4: The control board continues to move downward, and the control board drives the delay pressure control component to insert into the inner side of the piston tube, and the pressure sensing component drives the synchronous adjustment frame to move;

[0012] Step 5: The synchronization adjusting frame drives the adjusting tooth to move along the loop-shaped limiting frame through the force guiding rod. The adjusting tooth cooperates with the control wheel to rotate the threaded rod. The threaded rod drives the U-shaped connecting frame to move along the limiting plate. The U-shaped connecting frame drives the limiting clamping plate and the synchronization guiding plate to move synchronously. The limiting clamping plate limits the lower section of the pipe pile. The upper section of the pipe pile moves towards the lower section of the pipe pile under the traction of the hoisting machine. The synchronization guiding plate limits and guides the upper section of the pipe pile approaching the lower section of the pipe pile. The bottom end of the upper section of the pipe pile is accurately docked with the top end of the lower section of the pipe pile;

[0015] Step 8: Release the fixation of the installation base. The installation base continues to move along the slide rail, and repeat the steps of Step 1 - Step 7 until the construction of a row of pipe piles is completed.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the device is running, the self-leveling support unit moves along the slide rail. After moving to the designated location, the delayed transmission control component can first drive the self-leveling support unit to achieve a stable connection between the equipment and the ground. After the equipment is fixed, the self-leveling support unit completes the leveling work of the support shell. The lower pipe pile passes through the support shell and the self-leveling support unit and drills into the ground. The delayed transmission control component continues to run to drive the annular synchronous positioning guide component. The annular synchronous positioning guide component clamps and limits the top of the lower pipe pile, and can limit and guide the fall of the upper pipe pile. The upper pipe pile moves along the annular synchronous positioning guide component to the side close to the lower pipe pile under the traction of the hoisting machine. Under the restriction of the annular synchronous positioning guide component, the bottom end of the upper pipe pile accurately docks with the top end of the lower pipe pile. The automatic welding assembly completes the automatic welding of the pipe pile joints. After the installation is completed, the fixation of the equipment is released, and the equipment continues to move along the slide rail to realize the continuous installation of the horizontal row of pipe piles. Compared with the existing pile connection methods in the technology, there are welding methods and mechanical joint methods. Regardless of the joint form, joint centering is more difficult and time-consuming. The error in joint centering also affects the verticality and bearing performance of the pile. By setting a joint centering unit and cooperating with a self-leveling support unit, the accuracy of the docking between the upper section of the pipe pile and the lower section of the pipe column is guaranteed, and the verticality of the pipe pile after welding is guaranteed, thereby ensuring the stability and safety of the pipe pile construction.

By providing the ground drilling limit assembly 9, the delayed transmission control assembly 6 can be cooperated to achieve the fixation of the mounting base 7, thereby ensuring the stability and reliability of the equipment during use.

[0046] A pipe pile planting construction method, using the pipe pile planting auxiliary device described above, comprises the following steps:

[0047] Step 1: The slide rail 50 is fixed to the ground, and the mounting base 7 moves along the slide rail 50. After reaching the designated position, the control member 22 drives the control board 21 to move downward. The control board 21 cooperates with the fixing rod 25 to drive the first piston to move inside the pressure pipe 23, driving the ground drilling member 49 to drill into the ground, thereby completing the fixing of the mounting base 7.

[0048] Step 2: The power source 42 drives the annular support seat 39 to rotate so that the support shell 1 and the ground are on the same slope. The telescopic member 41 is then used to drive the support shell 1 to rotate around the connection end with the support column 40, thereby completing the leveling of the support shell 1.

[0049] Step 3: The lower-section pipe pile passes through the support shell 1 and the installation base 7 and then drills into the ground;

[0050] Step 4: The control board 21 continues to move downward. The control board 21 drives the delay pressure control member 28 to insert into the inner side of the piston pipe 27, and the pressure sensing member 29 drives the synchronous adjustment frame 18 to move;

[0051] Step 5: The synchronous adjustment frame 18 drives the adjusting tooth 13 to move along the loop-shaped limiting frame 14 through the force guiding rod 19. The adjusting tooth 13 cooperates with the control wheel 12 to realize the rotation of the threaded rod 11. The threaded rod 11 drives the U-shaped connecting frame 10 to move along the limiting plate 17. The U-shaped connecting frame 10 drives the limiting clamping plate 16 and the synchronous guiding plate 15 to move synchronously. The limiting clamping plate 16 limits the lower-section pipe pile, and the upper-section pipe pile moves towards the lower-section pipe pile under the traction of the hoisting machine. The synchronous guiding plate 15 limits and guides the upper-section pipe pile moving towards the lower-section pipe pile, and the bottom end of the upper-section pipe pile is accurately butted with the top end of the lower-section pipe pile;

[0052] Step 6: The winding and unwinding member 35 cooperates with the connecting side plate 34 to realize the lifting of the welding seat 33. The adjusting member 38 realizes the retraction of the welding torch 36. The driving member 31 drives the annular turntable 30 to rotate. The annular turntable 30 drives the welding torch 36 to rotate around the pipe pile. After welding a full circle, the welding between the two side pipe piles is completed;

[0053] Step 7: After the weld cools down, continue to drill the pipe pile, and repeat Steps 3 - 6 until the construction of one pipe pile is completed;

[0054] Step 8: Release the fixation of the installation base 7. The installation base 7 continues to move along the slide rail 50, and repeat Steps 1 - 7 until the construction of a row of pipe piles is completed.

[0055] The pipe pile planting auxiliary device and construction method, by setting a joint centering unit 2 and cooperating with a self-leveling support unit 3, ensures the accuracy of the docking between the upper pipe pile and the lower pipe column, and ensures the verticality of the pipe pile after welding, ensuring the stability and safety of the pipe pile construction, and the processing process does not require excessive human participation, reducing the labor intensity of personnel, the operation process is simple and easy to implement, speeds up the construction speed, and makes it easier to control the construction quality. By setting an annular synchronous positioning guide component 4 and cooperating with a delayed transmission control component 6, it can not only complete the limiting of the lower pipe pile, but also position and guide the upper pipe pile, greatly reducing the centering error, and can quickly complete the pile connection, with a good vertical centering effect. The delayed transmission control component 6 is set to complete the driving of the self-leveling support unit 3 and the annular synchronous positioning guide component 4 in sequence, which not only ensures the stability of the equipment during use, but also can achieve precise docking between the pipe piles. The operation process is simple and easy to implement, which speeds up the construction speed and makes the construction quality easier to control. By setting up the automatic welding component 5, automatic welding of the joints between the pipe piles can be achieved, which not only ensures the accuracy of welding, but also greatly improves the welding efficiency. By setting up the self-leveling support unit 3, not only can the delayed transmission control component 6 be cooperated with to complete the fixation of the equipment, ensuring the stability of the equipment during use, but also the support shell 1 can be leveled, so that the vertical centering effect is good.

[0056] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
