Description

Technical Field

[0001] The 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 are a type of pile foundation and are an indispensable building material for industrial and construction construction. Pipe piles are divided into prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and prestressed high-strength concrete pipe piles (PHC pipe piles) according to the concrete strength grade and wall thickness. It has the characteristics of large bearing capacity and convenient 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 types of pile sinking methods for prestressed concrete pipe piles, namely, the hammering method for soil extrusion, the static pressure method, and the drilling and pipe following method and the mid-excavation method for non-soil extrusion. Except for offshore platforms and port terminal projects, the prefabricated length of pipe piles can reach 50m. For other land transportation, due to the limitation of the minimum curvature radius of the road bend, the length of a single pipe pile generally does not exceed 20m. When the thickness of the soft soil layer is large, the buried depth of the pile foundation is large, and pile connection is required. Commonly used pile connection methods include welding and mechanical joints. Regardless of the joint form, it is difficult to center the joint and it takes a long time. The error in the centering of the joint also affects the verticality and bearing capacity of the pile. At the same time, because the river geology is mainly sand and gravel formations, the equipment cannot be effectively positioned during the construction of the main trench for pipe pile protection, resulting in the pipe pile being squeezed by the sand and gravel formation, which often causes the pile position to shift, thereby affecting the construction quality. Therefore, in view of the above situation, it is urgent to develop a pipe pile planting auxiliary device and construction method to overcome the shortcomings in current practical applications. 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.

[0005] To achieve the above object, the present invention provides the following technical solutions: A pipe pile planting auxiliary device comprises: a support shell; a self-leveling support unit, which is arranged on the outside of the support shell and connected to the support shell, and is used to support and fix the support shell and complete the leveling of the support shell; a slide rail, which is arranged on the outside of the self-leveling support unit, connected to the ground, and slidably connected to a slider fixedly connected to the outside of the self-leveling support unit, and is used to achieve the lateral movement of the entire device and complete the continuous installation of the pipe piles; a joint centering unit, which is connected to the support shell and the self-leveling support unit, and is used to cooperate with the leveled support shell to realize the vertical centering operation of the pipe pile joint and complete the pipe pile joint positioning Automatic welding; wherein, the joint centering unit includes: an annular synchronous positioning and guiding assembly, an automatic welding assembly and a delayed transmission and control assembly, the delayed transmission and control assembly is fixedly connected to the outside of the support shell, the delayed transmission and control assembly is connected to the self-leveling support unit, and is used to drive the self-leveling support unit to fix the equipment, the delayed transmission and control assembly is also connected to the annular synchronous positioning and guiding assembly arranged on the inner side of the support shell, and is used to cooperate with the support shell to limit the lower section of the pipe pile, and to position and guide the upper section of the pipe pile, and to realize the centering operation of the upper section of the pipe pile and the lower section of the pipe pile, and an automatic welding assembly is also arranged on the inner side of the support shell, which is used to cooperate with the support shell to complete the automatic welding at the pipe pile joint.

[0006] A pipe pile planting construction method, applied to the pipe pile planting auxiliary device described above, comprises the following steps: Step 1: The track is fixed on the ground, and the mounting base moves along the track. After reaching the specified 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 drilling component to drill into the ground, thereby fixing the mounting base; 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; Step 3: The lower pipe pile passes through the support shell and the installation base and then drills into the ground; Step 4: The control board continues to move downward, the control board drives the time-delay pressure control component to be inserted into the inner side of the piston tube, and the pressure sensing component drives the synchronous adjustment frame to move; Step Five: 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 pipe pile. The upper-section pipe pile moves towards the lower-section pipe pile under the traction of the hoisting machine. The synchronization guiding plate limits and guides the upper-section pipe pile approaching the lower-section pipe pile. The bottom end of the upper-section pipe pile is accurately butted with the top end of the lower-section pipe pile. Step Six: The winding and unwinding part cooperates with the connecting side plate to realize the lifting of the welding seat. The adjusting part realizes the retraction of the welding torch. The driving part drives the annular turntable to rotate. The annular turntable drives the welding torch to rotate around the pipe pile. After welding a full circle, the welding between the two side pipe piles is completed. Step Seven: After the weld seam cools down, continue to drill the pipe pile, and repeat the steps of Step Three - Step Six until the construction of one pipe pile is completed. Step Eight: Release the fixation of the installation base. The installation base continues to move along the track, and repeat the steps of Step One - Step Seven until the construction of one row of pipe piles is completed.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: When the device operates, the self-leveling support unit moves along the track. After moving to the designated location, the delay transmission control component can first drive the self-leveling support unit to realize the 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-section pipe pile passes through the support shell and the self-leveling support unit and then drills into the ground. The delay transmission control component continues to operate and drives the annular synchronous positioning and guiding component. The annular synchronous positioning and guiding component clamps and limits the top end of the lower-section pipe pile, and can limit and guide the falling of the upper-section pipe pile. The upper-section pipe pile moves towards the lower-section pipe pile along the annular synchronous positioning and guiding component under the traction of the hoisting machine. Under the limitation of the annular synchronous positioning and guiding component, the bottom end of the upper-section pipe pile is accurately butted with the top end of the lower-section pipe pile. The automatic welding component completes the automatic welding of the joint of the pipe pile. After the installation is completed, release the fixation of the equipment, and the equipment continues to move along the track to realize the continuous installation of the horizontal row of pipe piles. In the prior art, the pile connection methods include the welding method and the mechanical joint method. No matter which joint form, it is difficult to align the joints, and it takes a long time. The alignment error of the joints also affects the verticality and bearing performance of the piles. By setting the joint alignment unit and cooperating with the self-leveling support unit, the accuracy of the butt joint between the upper-section pipe pile and the lower-section pipe column is ensured, and the verticality of the pipe pile after welding is ensured, ensuring the stability and safety of the pipe pile construction. Moreover, the processing process requires less human participation, reducing the labor intensity of personnel. The operation process is simple and easy to implement, accelerating the construction speed, and the construction quality is easier to control. Description of the Drawings
