Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile splicing and positioning technology, specifically to a pile splicing and positioning device for implanted piles. Background Technology
[0002] Implanted composite piles are a new type of pile that combines the advantages and characteristics of traditional bored piles and PHC pipe piles or prestressed concrete solid square piles. At the same time, they effectively avoid the defects and drawbacks of the above two types of piles. The thickness of sediment in traditional bored piles is difficult to control, which has a great impact on bearing capacity. PHC pipe piles or prestressed concrete solid square piles are generally used in soft soil, fill, general cohesive soil, silt and other strata, and their application range is limited.
[0003] Implanted composite piles significantly improve the vertical compressive bearing capacity of single piles, enabling larger pile diameters and meeting the requirements of one pile per column foundation. They represent a new type of pile with relatively mature technology. The pile construction process generally consists of three main steps: drilling, low-strength concrete pouring, and implantation of high-strength PHC pipe piles or prestressed concrete solid square piles. They offer numerous advantages, including high bearing capacity, low economic cost, and good ecological benefits.
[0004] During pile driving, the positioning of the high-strength PHC pipe piles in the third step and the connection of the pile heads of the upper and lower pile sections are mainly carried out manually. Since the borehole diameter in the first step of the process must be larger than the diameter of the high-strength PHC pipe pile or the width of the prestressed concrete solid square pile, the pipe pile or square pile is generally lifted by a crane and placed into the borehole. Manual positioning and splicing require the availability of pile verticality monitoring instruments (long strip leveling rods or theodolites) and personnel on-site to continuously measure the verticality of the pile. Manual control of the horizontal misalignment between the upper and lower pile sections is often achieved through winches or manual experience; the verticality of the pile is controlled by the long strip leveling rod or theodolite, and adjusted by the pile driving machine's own system. However, in practical engineering, manual operation and theodolites cannot fully meet the requirements for correction and positioning at the splice points. Misalignment between the upper and lower pile sections can negatively impact the pile foundation's bearing capacity, and in severe cases, may even lead to pile breakage. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] This application provides an implantable pile connection positioning device, which solves the problems of poor positioning accuracy and low efficiency of implantable pile connection.
[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] The fixed base 10 is installed on the pile driver, and the sliding block 20 is slidably connected to the fixed base 10 along the X direction.

[0040] The clamp base 30 has a rearwardly extending positioning notch 31 at its front end, which is used to accommodate and initially position the lower pile section.
[0041] A set of lower clamps 40 is slidably connected to the upper part of the clamp base 30 along the Y direction, and a set of upper clamps 50 is slidably connected to the upper part of the lower clamps 40 along the Y direction; a third hydraulic rod 32, a fourth hydraulic rod 33, a fifth hydraulic rod 34 and a sixth hydraulic rod 35 are provided on both sides of the clamp base 30.

[0042] A bubble level 36 is installed on the clamp base 30 to observe whether the clamp base 30 is level. If the bubble in the bubble level 36 is centered, construction can proceed normally.

[0044] like Figure 1 , Figure 2 As shown, the slide 20 is connected to the slide rail of the fixed seat 10, and the clamp base 30 is also connected to the slide rail of the fixed seat 10, further improving the stability of the clamp base 30.
[0045] like Figure 1 , Figure 2 As shown, the lower clamp 40 includes: a pair of lower clamping frames 41 and a pair of lower clamping teeth 42;
[0046] The lower clamping frame 41 is connected to the slide rail of the clamping base 30, and the lower clamping tooth 42 is connected to the corresponding lower clamping frame 41 slide rail.
[0047] The lower clamping frame 41 has a first mounting hole 43 corresponding to the third hydraulic rod 32 and a first through hole 44 corresponding to the fourth hydraulic rod 33. The lower clamping tooth 42 has a second mounting hole corresponding to the fourth hydraulic rod 33. The output end of the third hydraulic rod 32 is interference-fitted with the first mounting hole 43, and the fourth hydraulic rod 33 passes through the first through hole 44 and is interference-fitted with the second mounting hole.
[0048] The pairs of lower clamping frames 41 are clamped together under the drive of the third hydraulic rod 32, providing a stable sliding track for the lower clamping teeth 42. Then, the pairs of lower clamping teeth 42 are clamped and locked to the lower pile under the drive of the fourth hydraulic rod 33.
[0049] like Figure 1 , Figure 2 As shown, the lower clamping frame 41 is provided with a positioning component, which includes: a first positioning block 45 and a first positioning hole;
[0050] The inner ends of the two lower clamping frames 41 are respectively provided with a first positioning block 45 and a first positioning hole. When the pair of lower clamping frames 41 are clamped under the drive of the third hydraulic rod 32, the first positioning block 45 is inserted into the first positioning hole to improve the stability of the lower clamping frame 41.

[0054] The paired upper clamping frames 51 are clamped together under the drive of the fifth hydraulic rod 34, providing a stable sliding track for the upper clamping teeth 52. Then, the paired upper clamping teeth 52 are clamped and locked to the upper pile under the drive of the sixth hydraulic rod 35.
[0055] like Figure 1 , Figure 2 As shown, the upper clamping frame 51 is provided with a positioning component, which includes: a second positioning block 55 and a second positioning hole;
[0056] The inner ends of the two upper clamping frames 51 are respectively provided with a second positioning block 55 and a first positioning hole. When the pair of upper clamping frames 51 are clamped under the drive of the fifth hydraulic rod 34, the second positioning block 55 is inserted into the first positioning hole to improve the stability of the upper clamping frame 51.
[0057] The lower clamping teeth 42 and upper clamping teeth 52 are available in various sizes, with each type corresponding to a specific pile size. This allows the clamping teeth to adapt to different pile types, such as pipe piles and square piles, and to replace the lower clamping teeth 42 and upper clamping teeth 52, simply slide the original clamping teeth out from the inner end of the corresponding clamping frame and disengage the mounting holes from the corresponding hydraulic rods. The replacement clamping teeth are then slid into the inner end of the clamping frame and the mounting holes are aligned with the corresponding hydraulic rods to complete the replacement.
[0058] When the lower clamping frame 41 is fully opened, the opening gap is greater than the diameter of the lower pile section; when the upper clamping frame 51 is fully opened, the opening gap is greater than the diameter of the upper pile section.
[0059] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0060] In this embodiment of the utility model, during the pile driver construction and pile implantation process, when the upper and lower pile sections need to be connected, the first hydraulic rod 11 drives the slide 20 to extend out from the fixed seat 10, the second hydraulic rod 21 drives the clamp base 30 to continue extending relative to the slide 20, so that the lower pile section enters the positioning notch 31, the third hydraulic rod 32 drives the lower clamping frame 41 to clamp and splice, the fourth hydraulic rod 33 drives the lower clamping teeth 42 to clamp and lock the lower pile section, and the horizontality is adjusted by adjusting the hydraulic lifting legs of the pile driver so that the bubble of the bubble level 36 is centered, the fifth hydraulic rod 34 drives the upper clamping frame 51 to clamp and splice, and the sixth hydraulic rod 35 drives the upper clamping teeth 52 to clamp and lock the upper pile section, which greatly reduces the planar deviation between the upper and lower pile sections. The gap between the lower clamping device 40 and the upper clamping device 50 facilitates the butt welding of the upper and lower pile sections, which greatly improves the positioning accuracy and efficiency of the pile implantation and splicing.
