Description

Technical Field

[0001] This utility model relates to the field of pipe pile technology, and in particular to a variable diameter pile and a lamp holder support structure. Background Technology

[0002] With the acceleration of urbanization, urban main roads, expressways, and coastal ports have placed higher demands on street light construction. Traditional lamp holder foundation materials generally use concrete piles of equal diameter. The load on the concrete pile is mainly concentrated in the lower part buried in the soil, while the upper part of the concrete pile exposed in the soil has redundant material, which results in unnecessary waste. Utility Model Content

[0003] This utility model provides a variable diameter pile and a lamp holder support structure, which can reduce the material used in the pile body and has both stability and economy.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] According to a first aspect of the present invention, an embodiment of the present invention provides a variable diameter pile, comprising a first pile segment, a transition segment, and a second pile segment arranged along the length direction of the variable diameter pile. The first pile segment, the transition segment, and the second pile segment are sequentially connected. The outer diameter of the first pile segment is larger than the outer diameter of the second pile segment. In a direction parallel to the length direction of the variable diameter pile and pointing from the first pile segment to the second pile segment, the outer diameter of the transition segment gradually decreases.

[0006] In some embodiments, the first pile segment is provided with a constant diameter along the length direction of the variable diameter pile, or the outer diameter of the first pile segment gradually decreases in a direction parallel to the length direction of the variable diameter pile and pointing from the first pile segment to the second pile segment.

[0007] In some embodiments, the second pile segment is provided with a constant diameter along the length direction of the variable diameter pile, or the outer diameter of the second pile segment gradually decreases in a direction parallel to the length direction of the variable diameter pile and pointing from the first pile segment to the second pile segment.

[0008] In some embodiments, a connecting hole for installing a sleeve is provided on the end face of the first pile segment away from the transition section.

[0009] In some embodiments, an annular groove is provided at the end of the second pile segment away from the transition section, and the annular groove surrounds the circumference of the second pile segment.

[0010] In some embodiments, a reinforcing cage is embedded inside the variable diameter pile.

[0011] In some embodiments, the reducing pile has a central hole that extends through the reducing pile along its length.

[0012] According to a second aspect of the present invention, an embodiment of the present invention provides a lamp holder support structure, including soil and a variable diameter pile as described in any of the first aspects above, wherein the first pile segment and the transition segment are both buried in the soil.

[0013] In some embodiments, the soil has a trapezoidal cross-sectional shape in the vertical section, and the width of the soil gradually decreases in the upward direction.

[0014] This utility model has at least the following beneficial effects: The variable diameter pile of this utility model includes a first pile segment, a transition segment, and a second pile segment arranged along the length direction of the variable diameter pile. The first pile segment, the transition segment, and the second pile segment are connected sequentially. The outer diameter of the first pile segment is larger than the outer diameter of the second pile segment. In use, the first pile segment is buried in the soil and can withstand a greater load, ensuring the stability of the variable diameter pile. The outer diameter of the second pile segment is smaller and less material is used, which can reduce the manufacturing cost of the entire variable diameter pile. Therefore, the variable diameter pile of this utility model has both stability and economy. Attached Figure Description

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a variable diameter pile, such as... Figure 1 As shown, the pile includes a first pile segment 110, a transition segment 130, and a second pile segment 120 arranged along the length direction of the variable diameter pile. The first pile segment 110, the transition segment 130, and the second pile segment 120 are connected sequentially. The outer diameter of the first pile segment 110 is larger than the outer diameter of the second pile segment 120. In the direction parallel to the length direction of the variable diameter pile and from the first pile segment 110 to the second pile segment 120, the outer diameter of the transition segment 130 gradually decreases.

[0027] When using the variable diameter pile of this embodiment, the first pile segment 110 is embedded in the soil, while the second pile segment 120 is exposed outside the soil. Since the outer diameter of the first pile segment 110 is larger, it can withstand a larger load, ensuring the stability of the variable diameter pile. The outer diameter of the second pile segment 120 is smaller, requiring less material, which can reduce the overall manufacturing cost of the variable diameter pile. Therefore, the variable diameter pile of this embodiment combines stability and economy.

[0028] Meanwhile, due to the presence of the transition section 130, the first pile section 110 can transition to the second pile section 120 relatively smoothly, without any protruding edges on the outer diameter, thus avoiding stress concentration. Furthermore, the outer surface of the entire variable diameter pile is relatively smooth, facilitating pile driving and demolding after molding.

[0029] In some embodiments, such as Figure 1 As shown, the first pile segment 110 is set with a uniform diameter along the length direction of the variable diameter pile. The first pile segment 110 is relatively regular and uniform, which is convenient for manufacturing and forming.

[0030] In other embodiments, such as Figure 2 As shown, in the direction parallel to the length of the variable-diameter pile and pointing from the first pile segment 110 to the second pile segment 120, the outer diameter of the first pile segment 110 gradually decreases. Since the first pile segment 110 is buried in the soil, the deeper the first pile segment 110 is buried, the greater the load it bears. This structure can adapt to the distribution of load forces and has a certain degree of economy.

[0031] In some embodiments, such as Figure 1 As shown, the second pile segment 120 is set with a uniform diameter along the length direction of the variable diameter pile. The second pile segment 120 is relatively regular and uniform, which is convenient for manufacturing and forming.

[0032] In some embodiments, such as Figure 3 As shown, in the direction parallel to the length of the variable-diameter pile and pointing from the first pile segment 110 to the second pile segment 120, the outer diameter of the second pile segment 120 gradually decreases. Since the second pile segment 120 is exposed in the soil, the requirements for its mechanical properties are relatively low. The gradual reduction in outer diameter can reduce the material used in the second pile segment 120, further reducing the overall manufacturing cost of the variable-diameter pile.

[0033] In some embodiments, such as Figure 1 As shown, a connecting hole 111 for installing a sleeve is provided on the end face of the first pile segment 110 away from the transition segment 130. The sleeve for connecting the prestressed steel bars can be fixed in the connecting hole 111, which improves the stability of the installation and makes the bottom surface of the variable diameter pile relatively flat.

[0034] In some embodiments, such as Figure 1 As shown, an annular groove 121 is provided at the end of the second pile segment 120 away from the transition segment 130, and the annular groove 121 surrounds the circumference of the second pile segment 120.

[0035] In some embodiments, a reinforcing cage is embedded in the variable diameter pile. The reinforcing cage may include prestressed steel bars and stirrups. The prestressed steel bars may extend along the length of the variable diameter pile, and the stirrups may be wrapped around the outside of the prestressed steel bars and may be arranged in a spiral shape.

[0036] In some embodiments, such as Figure 1 As shown, the variable diameter pile has a central hole 101, which penetrates the variable diameter pile along its length, making the variable diameter pile a hollow structure. While ensuring the mechanical properties of the variable diameter pile, the material used in the variable diameter pile can be further reduced, thus lowering the overall manufacturing cost of the variable diameter pile.

[0037] Based on the above embodiments, in order to further illustrate the first and second pile segments of the variable diameter pile, the following specific embodiments are provided.

[0038] Example 1:

[0039] like Figure 1 As shown, the first pile segment 110 and the second pile segment 120 are both set with equal diameters along the length direction of the variable diameter pile.

[0040] Example 2:

[0041] like Figure 2 As shown, in the direction parallel to the length of the variable-diameter pile and pointing from the first pile segment 110 to the second pile segment 120, the outer diameter of the first pile segment 110 gradually decreases, while the second pile segment 120 is set with a constant diameter along the length of the variable-diameter pile. The outer diameter of the end of the first pile segment 110 connected to the transition section 130 is larger than the outer diameter of the second pile segment 120.

[0042] Example 3:

[0043] like Figure 3 As shown, the first pile segment 110 is set with a constant diameter along the length direction of the variable diameter pile. In the direction parallel to the length direction of the variable diameter pile and pointing from the first pile segment 110 to the second pile segment 120, the outer diameter of the second pile segment 120 gradually decreases. The outer diameter of the end of the second pile segment 120 that connects to the transition section 130 is smaller than the outer diameter of the first pile segment 110.

[0044] Example 4:

[0045] In the direction parallel to the length of the variable-diameter pile and from the first pile segment to the second pile segment, the outer diameter of both the first and second pile segments gradually decreases, and the outer diameter of the end of the first pile segment connected to the transition segment is greater than the outer diameter of the end of the second pile segment connected to the transition segment.

[0046] An embodiment of this utility model provides a lamp holder support structure, such as... Figure 4 As shown, the structure includes soil 200 and a variable-diameter pile from any of the above embodiments. For a description of the variable-diameter pile, please refer to the above embodiments; further details will not be repeated here. The first pile segment 110 and the transition segment 130 are both embedded in the soil 200, while the second pile segment 120 is exposed outside the soil 200.

[0047] In some embodiments, the soil body 200 can be piled up in a similar shape to a mound, the cross-sectional shape of the soil body 200 in the vertical section is trapezoidal, and the width of the soil body 200 gradually decreases in the upward direction.

[0048] like Figure 4 As shown, the variable diameter piles included in the lamp holder support structure of this embodiment are the same as those in Embodiment 1; as Figure 5 As shown, the variable-diameter piles included in the lamp holder support structure of this embodiment are the same as those in Embodiment 2; as Figure 6 As shown, the variable diameter piles included in the lamp holder support structure of this embodiment are the variable diameter piles corresponding to Embodiment 3; of course, the variable diameter piles included in the lamp holder support structure can also be the variable diameter piles corresponding to Embodiment 4.
