Description

Technical Field

[0001] This utility model relates to the field of precast concrete piles, and in particular to a support pile. Background Technology

[0002] Currently, precast reinforced concrete piles refer to foundations where components are prefabricated in a precast component processing plant, cured to the design strength, transported to the construction site, driven into the soil using a pile driver, and then a foundation beam is poured on top of the piles. Precast piles are used in riverbank slope protection construction. During construction, multiple precast piles are arranged side-by-side and driven into the riverbed soil near the bank. A foundation beam is then poured on top of the precast piles for constructing trestle bridges, etc. Due to the river's flow, the water erodes the riverbank soil. The water flow between adjacent precast piles can easily carry soil out through the gaps between them, causing soil loss and potentially leading to bank collapse over time. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a method for supporting piles.

[0004] The present invention provides a support pile, which adopts the following technical solution: A support pile includes a pile body, the pile body enclosing a main body and protrusions disposed on the left and right sides of the main body, the protrusions being symmetrically distributed diagonally with the center of the main body as the center of symmetry.

[0005] The aforementioned technical solution utilizes a symmetrically distributed protrusion design along the diagonals of both sides to form a self-locking interlocking structure, ensuring the overall stability and structural reliability of the support system after installation. This geometric symmetry enhances the lateral stiffness of the pile, making it particularly suitable for riverbank protection and other water erosion scenarios, effectively preventing the protection system from failing due to pile deflection. Compared to traditional rectangular piles, it offers higher assembly efficiency and eliminates the need for additional positioning devices.

[0006] As a preferred embodiment of this utility model, a steel reinforcement cage is provided inside the pile body, the steel reinforcement cage includes main bars and ring bars, and at least one main bar is provided in each protrusion.

[0007] Through the above technical solution, main reinforcement bars are installed inside the protrusion, extending the stress on the pile from the main pile body to the protrusion area, forming a continuous stress system. This structure improves the shear bearing capacity of the protrusion and avoids concrete cracking caused by stress concentration at the root of the protrusion.

[0008] As a preferred embodiment of this utility model, the cross-section of the protrusion is rectangular, and the thickness of the protrusion in the front-rear direction of the pile body is half the thickness of the pile body in the front-rear direction.

[0009] Through the above technical solution, the thickness of the rectangular protrusion is precisely half that of the main pile body, achieving the effect that the total thickness of adjacent piles after splicing is equal to that of a single pile. This ensures both the matching stiffness at the connection and the formation of a labyrinthine water-stopping path through the interlocking protrusions, reducing seepage flow and solving the problem of soil seepage at the joints of traditional support piles.

[0010] As a preferred embodiment of this utility model, the cross-section of the protrusion includes three straight ends and one inclined end, the inclined end being the end where two protrusions are close to each other, and the sum of the maximum and minimum thickness of the protrusion in the front-rear direction of the pile body is the same as the thickness of the pile body in the front-rear direction.

[0011] Through the above technical solutions, the inclined end protrusion design realizes the self-locking interlocking of adjacent piles, and forms a progressive clamping mechanism through the inclined geometry, which significantly improves the engineering adaptability of the support system while ensuring the uniformity of the overall thickness after splicing.

[0012] As a preferred embodiment of this utility model, the pile body is further provided with water permeable holes, which are located on the side of the pile body in the front-rear direction.

[0013] The above technical solution uses permeable holes to balance the water pressure inside and outside the support pile and prevent water accumulation from damaging the structural stability.

[0014] As a preferred embodiment of this utility model, the pile body is further provided with a ladder, which is located on one side of the pile body in the front-rear direction.

[0015] The above technical solution, by setting up a ladder, can provide both maintenance access and emergency escape functionality.

[0016] As a preferred embodiment of this utility model, a decorative layer is further provided on one side of the pile body in the front-rear direction.

[0017] The above technical solution, by setting up a decorative layer, can achieve the integration of landscape and concrete protection.

[0018] As a preferred embodiment of this utility model, connecting end plates are provided at both ends of the pile body length, and through-reinforcement holes are provided on the connecting end plates, with the main reinforcement bars disposed in the through-reinforcement holes.

[0019] By using the above technical solution and setting up connecting end plates, the impact resistance of the pile can be improved.

[0020] As a preferred embodiment of this utility model, the connecting end plate is provided with a mounting hole, and a sleeve is provided in the mounting hole, the sleeve being connected to the main reinforcing bar.

[0021] The above technical solution, which uses an end plate sleeve connection, provides better fatigue resistance and corrosion protection, enhances durability, and also improves the efficiency of pile preparation.

[0022] As a preferred embodiment of this utility model, connecting sleeves are provided at both ends of the pile body length. The sleeves are connected to the main reinforcement bars. A pressure ring is also connected to the sleeve. The end face of the pressure ring away from the sleeve is flush with the end face of the pile body.

[0023] Through the above technical solution, the prestress retention mechanism of the pressure ring-sleeve composite structure ensures that the concrete at the pile end is always under compression through the axial constraint force of the pressure ring. The design of the pressure ring improves the pile's impact resistance, and the pressure ring can significantly reduce costs compared to end plates.

[0024] In summary, this utility model has at least one of the following beneficial technical effects: 1. This utility model's support pile achieves multi-dimensional reinforcement of the support system through a protrusion interlocking design. The protrusions, symmetrically distributed diagonally on both sides, form a self-locking interlocking structure. Their geometric symmetry not only significantly improves the lateral stiffness of the pile but also ensures, through precise thickness control at the inclined or rectangular ends, that the overall thickness of adjacent piles after assembly remains completely consistent with that of a single pile. This design maintains stiffness matching at the connection points and constructs a labyrinthine water-stopping path through protrusion interlocking, fundamentally solving the technical pain point of soil seepage at the joints of traditional support piles. The main reinforcement bars inside the protrusions extend the stress from the main pile body to the protrusion area, forming a continuous and complete stress system. This effectively avoids the risk of concrete cracking caused by stress concentration at the root of the protrusions, enabling the support structure to maintain excellent overall stability even in soft soil foundations or vibrating environments.

[0025] 2. The permeable holes balance the water pressure difference inside and outside the support piles, the embedded ladder design meets the needs of daily maintenance and emergency escape, and the application of the decorative layer makes the engineering structure blend naturally with the surrounding landscape.

[0035] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0036] Example 1: Reference Figures 1 to 2 This embodiment discloses a support pile, including a pile body, which is a hollow pile structure. The pile body encloses a main body 1 and protrusions 2 disposed on the left and right sides of the main body 1. The protrusions 2 are symmetrically distributed diagonally with the center of the main body of the pile body as the center of symmetry. In this embodiment, the cross-section of the protrusions 2 is a rectangular structure. The protrusions 2 and the main body 1 are integrally formed. The thickness of the protrusions 2 in the front-rear direction of the pile body is half the thickness of the pile body in the front-rear direction.

[0037] A steel reinforcement cage is installed inside the pile body. The steel reinforcement cage includes main reinforcement bars 3 and ring reinforcement bars. At least one main reinforcement bar 3 is provided in each protrusion 2. In this embodiment, two main reinforcement bars 3 are provided in each protrusion 2, which ensures the strength of the protrusion 2.

[0038] Connecting end plates 4 are provided at both ends of the pile along its length. Through holes for reinforcing bars are provided on the connecting end plates 4. The two ends of the main reinforcing bars 3 are respectively placed in the through holes of the two connecting end plates 4.

[0039] Reference Figure 2In this embodiment, during the support pile installation, adjacent support piles are fitted together by protrusions 2. Since the thickness of protrusion 2 in the front-rear direction of the pile body is half the thickness of the pile body in the front-rear direction, the overall thickness of the connection between two adjacent support piles is the same as the thickness of the main pile body. This ensures the rigidity of the support piles. At the same time, the cooperation of protrusions 2 on the two support piles can seal the gaps between adjacent support piles, preventing water flow from carrying soil out of the gaps between adjacent support piles. In addition, the two adjacent support piles have the same thickness in the width direction (front-rear direction) as the support pile body due to the mutual contact of the two protrusions 2, which greatly improves the shear resistance of the support pile connection.

[0040] In this embodiment, each support pile is also provided with a water-permeable hole 5 and a ladder. The water-permeable hole 5 is located on the front-rear side of the pile body, and the ladder is located on the front-rear side of the pile body. The water-permeable hole 5 is used to balance the water pressure inside and outside the support pile and prevent water accumulation from damaging the structural stability. The ladder provides a maintenance passage and emergency escape function. A decorative layer is also provided on the front-rear side of the support pile body. In this embodiment, the decorative layer is a layer of wood grain paint applied to the pile body. The decorative layer achieves the integration of landscape and concrete protection.

[0041] Example 2: Reference Figure 3 and Figure 4 In this embodiment, everything else is the same as in embodiment 1. The difference is that in this embodiment, the cross-section of the protrusion 2 includes three straight ends and one inclined end. The inclined end is the end where two protrusions 2 are close to each other. The sum of the maximum and minimum thickness of the protrusion 2 in the front-back direction of the pile body is the same as the thickness of the pile body in the front-back direction.

[0042] Reference Figure 4 In this embodiment, when the support piles are being supported, two adjacent support piles are fitted together by protrusions 2. When fitted together, the two protrusions 2 are fitted together by the inclined ends of the protrusions 2. Since the sum of the maximum and minimum thicknesses of the protrusions 2 in the front-rear direction of the pile body is the same as the thickness of the pile body in the front-rear direction, the overall thickness of the connecting part between two adjacent support piles is the same as the thickness of the pile body 1. This ensures the rigidity of the support piles. At the same time, the cooperation between the protrusions 2 on the two pile bodies can seal the gaps between adjacent pile bodies, preventing water from flowing out of the gaps between adjacent pile bodies.

[0043] Example 3: Reference Figure 5 and Figure 6In this embodiment, the rest is the same as in Embodiments 1 and 2, except that a countersunk hole 6 is provided on the connecting end plate 4, and a sleeve 7 is provided in the countersunk hole 6. The sleeve 7 is connected to the main reinforcement 3. By using the sleeve 7 for connection, fatigue resistance and corrosion protection are better, and durability is stronger. In this embodiment, Figure 5 The diagram only shows the structure of the rectangular bump 2 used in Embodiment 1, and does not show the structure of the rectangular bump 2 in Embodiment 2.

[0044] Example 4: Reference Figure 7 and Figure 8 In this embodiment, all other aspects are the same as in embodiment 1 or embodiment 2. The difference is that in this embodiment, end plates are not provided at both ends of the length of the support pile, and connecting sleeves 7 are provided at both ends of the length of the pile. The sleeves 7 are connected to the main reinforcement 3, and pressure rings 8 are also connected to the sleeves 7. The end face of the pressure ring 8 away from the sleeve 7 is flush with the end face of the pile. In this embodiment, the pressure ring 8 is fixedly installed to the sleeve 7 by threads.

[0045] The pressure ring 7 ensures that the concrete along the length of the connecting sleeve 7 retains prestress after tension release, thus guaranteeing the strength of the pile body 1. During pile driving, the pressure ring 8 also protects the connecting sleeve 7, preventing tilting. Most importantly, the pressure ring 8 improves the driveability of the support pile during construction. During pile driving, the force of the pile driver is primarily applied to the pressure ring 8, preventing damage to the top of the pile. Furthermore, the pressure ring 8 is inexpensive, effectively saving costs. In this embodiment, Figure 7 The diagram only shows the structure of the rectangular bump 2 used in Embodiment 1, and does not show the structure of the rectangular bump 2 in Embodiment 2.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
