Description

Technical Field

[0001] The utility model relates to the technical field of pipe piles, in particular to an anti-settling pipe pile. Background Art

[0002] In the field of construction engineering, pile foundation is an extremely important foundation form, which consists of piles and caps connected to the top of the piles. Pile foundations can be divided into low cap pile foundations (the pile body is completely buried in the soil, and the bottom of the cap is in contact with the soil) and high cap pile foundations (the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground) according to the relative position of the pile body, the ground and the cap. Building pile foundations usually use low cap pile foundations.

[0003] In actual engineering applications, pile foundations can be further divided into single pile foundations (independent foundations that use one pile, usually a large diameter pile, to bear and transfer the load of superstructures such as columns) and pile group foundations (pile foundations composed of more than two piles), among which the single pile in the pile group foundation is called a foundation pile.

[0004] When laying foundation piles in areas with relatively soft soil, due to the relatively weak bearing capacity of the soil, the foundation piles are easily affected by the load transmitted by the superstructure and the changes in the surrounding soil, resulting in settlement, which not only affects the stability of the building structure, but also may lead to a series of safety hazards. In order to solve this problem, many technicians have been exploring and developing relevant technologies and devices that can effectively prevent the settlement of foundation piles. Some existing measures still have certain limitations in practical applications. Therefore, it is necessary to design a more effective anti-settlement pipe pile to improve this situation. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-settling pipe pile to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An anti-settling pipe pile comprises a pipe pile, wherein the inner wall of the pipe pile is provided with an anti-settling component for preventing the settlement.

[0008] The anti-settling assembly includes a center rod, and also includes a positioning reinforcement ring threadedly connected to the outer wall of the center rod from top to bottom, a fixed downward pressure ring, a movably connected downward sleeve and a slidably connected separation conical block, and the top of the separation conical block is provided with a sliding hole for adapting to the insertion of the center rod.

[0009] The bottom end of the downward sleeve is rotatably connected with an expansion fin, the inner wall of the pipe pile is provided with an oblique through hole for adapting to the insertion of the expansion fin, and the expansion fin is fixedly connected with an auxiliary spring on one side close to the connection end of the downward sleeve.

[0010] The above technical solution is adopted, in which the center rod, the positioning reinforcement ring, the downward pressure ring, the downward sleeve, the expansion fins and the oblique penetration holes are used in coordination, so that after the pipe pile is driven into the soil, the expansion fins can be inserted into the soil, thereby improving the firmness of the pipe pile installation in the soil and further improving the settlement of the pipe pile.

[0011] A further improvement of the technical solution of the utility model is that the inner wall of the downward sleeve is movably connected to the outer wall of the center rod, the inner wall of the sliding hole is movably connected to the outer wall of the center rod, and the bottom surface of the downward pressure ring overlaps the top of the downward sleeve.

[0012] A further improvement of the technical solution of the utility model is that the outer wall of the positioning reinforcement ring is fixedly connected to the inner wall of the pipe pile.

[0013] A further improvement of the technical solution of the utility model is that the outer wall of the separation cone block is fixedly connected to the inner wall of the pipe pile.

[0014] A further improvement of the technical solution of the utility model is that the top outer wall of the separation cone block is movably connected to the bottom surface of the expansion fin.

[0015] The above technical solution is adopted, in which the auxiliary spring fixed on the side of the expansion fin exerts a pulling force on it, so that it remains in a retracted state when not in use, thereby preventing the expansion fin from extending from the oblique outlet hole when the pipe pile is not in use, thereby affecting the normal use of the pipe pile.

[0016] A further improvement of the technical solution of the utility model is that the inner wall of the oblique penetration hole is plugged into the outer wall of the bottom end of the expansion fin.

[0017] A further improvement of the technical solution of the utility model is that: the top end of the central rod is fixedly connected with a multilateral socket, the outer wall of the multilateral socket is sleeved with an adapting sleeve, and the top end of the adapting sleeve is fixedly connected with a detachable adjusting disk.

[0018] By adopting the above technical solution, the detachable adjustment disk and the adapter sleeve are sleeved on the outer wall of the multilateral socket to adjust the center rod. After the adjustment is completed, the detachable adjustment disk can be removed to facilitate the use of the device.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides an anti-settling pipe pile, which uses a center rod, a positioning reinforcement ring, a downward pressure ring, a downward sleeve, an expansion fin and an oblique penetration hole in coordination, so that after the pipe pile is driven into the soil, the expansion fin can be inserted into the soil, thereby improving the firmness of the pipe pile installed in the soil and further improving the settlement of the pipe pile.

The utility model provides an anti-sinking pipe pile, which utilizes the pulling force of the auxiliary spring fixed on the side of the expansion fin to keep it in a retracted state when not in use, thereby preventing the expansion fin from extending from the oblique penetration hole when the pipe pile is not in use, thereby affecting the normal use of the pipe pile.

[0022] 3. The utility model provides an anti-settling pipe pile, which uses a detachable adjustment disk and an adaption sleeve to be sleeved on the outer wall of a multilateral socket to adjust the center rod. After the adjustment is completed, the detachable adjustment disk can be removed to facilitate the use of the device. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention is further described in detail below in conjunction with the embodiments:

[0031] Example 1

[0032] like Figure 1-5 As shown, the utility model provides an anti-settling pipe pile, comprising a pipe pile 1, the inner wall of which is provided with an anti-settling component 4 for preventing settling.

[0033] The anti-settling component 4 includes a center rod 5, and also includes a positioning reinforcement ring 7 threadedly connected to the outer wall of the center rod 5 from top to bottom, a fixedly connected downward pressure ring 11, a movably connected downward sleeve 8 and a slidably connected separation cone block 10. The top of the separation cone block 10 is provided with a sliding hole 12 for adapting to the insertion of the center rod 5.

[0034] The bottom end of the downward sleeve 8 is rotatably connected to the expansion fin 9. The inner wall of the pipe pile 1 is provided with an oblique through hole 2 for adapting to the expansion fin 9. The expansion fin 9 is fixedly connected to an auxiliary spring 14 on one side close to the connection end with the downward sleeve 8.

[0035] The outer wall of the positioning reinforcement ring 7 is fixedly connected to the inner wall of the pipe pile 1 .

[0036] Example 2

[0037] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the inner wall of the lower sleeve 8 is movably connected to the outer wall of the center rod 5, the inner wall of the sliding hole 12 is movably connected to the outer wall of the center rod 5, and the bottom surface of the lower pressure ring 11 overlaps the top of the lower sleeve 8.

[0038] The outer wall of the separation cone block 10 is fixedly connected to the inner wall of the pipe pile 1 , and the top outer wall of the separation cone block 10 is movably connected to the bottom surface of the expansion fin 9 .

[0039] The inner wall of the oblique penetration hole 2 is plugged into the outer wall of the bottom end of the expansion fin 9, and the auxiliary spring 14 fixed on the side of the expansion fin 9 pulls it to keep it in a retracted state when not in use, thereby preventing the expansion fin 9 from extending out of the oblique penetration hole 2 when the pipe pile 1 is not in use, thereby affecting the normal use of the pipe pile 1.

[0040] The top of the center rod 5 is fixedly connected to a multilateral socket 6, the outer wall of the multilateral socket 6 is sleeved with an adapting sleeve 13, the top of the adapting sleeve 13 is fixedly connected to a detachable adjusting disk 3, and the center rod 5 is adjusted by sleeved on the outer wall of the multilateral socket 6 with the detachable adjusting disk 3 and the adapting sleeve 13. After the adjustment is completed, the detachable adjusting disk 3 can be removed to facilitate the use of the device.

[0041] The following is a detailed description of the working principle of the anti-settlement pipe pile.

[0042] like Figure 1-5 As shown, when in use, the pipe pile 1 is driven into the soil. When the pipe pile 1 is located in the soil, the adapter sleeve 13 at the bottom end of the detachable adjusting disk 3 is sleeved on the outer wall of the multilateral socket 6. Then, by rotating the detachable adjusting disk 3, the center rod 5 is driven to rotate. During the rotation process, the center rod 5 uses the effect of the thread on the inner wall of the positioning reinforcement ring 7 to drive the downward pressure ring 11 to move downward. The downward pressure ring 11 pushes the downward sleeve 8 to move downward. During the downward movement of the downward sleeve 8, the expansion fin 9 is obliquely inserted into the inner wall of the oblique outlet hole 2 under the action of the inclined surface of the cone top of the separation conical block 10. As the center rod 5 continues to move downward, the expansion fin 9 will be pushed from the oblique outlet hole 2 into the soil.

[0043] Afterwards, after the adjustment is completed, the detachable adjustment disk 3 can be removed from the multilateral socket 6 .

[0044] Before the expansion fins 9 are expanded by the force of the cone top of the separated conical block 10, they will remain in a retracted state under the elastic force of the auxiliary spring 14 to prevent the expansion fins 9 from extending from the oblique outlet hole 2 when the pipe pile 1 is not in use, thereby affecting the normal use of the pipe pile 1.

[0045] Concrete pouring holes can be opened on the surfaces of the positioning reinforcement ring 7 and the separation cone block 10 as needed, so that concrete can be poured into the pipe pile 1 according to actual needs later.

[0046] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to a general technician in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
