Abstract
Description
Technical Field
[0001] This application relates to the field of concrete pipe pile technology, specifically a concrete pipe pile suitable for construction on soft soil foundations. Background Technology
[0002] Concrete pipe piles are a type of pile made of concrete, primarily used for foundation construction.
[0003] An existing patent (publication number: CN222008908U) discloses a concrete pipe pile suitable for soft soil foundations, relating to the field of concrete pipe pile installation technology. It includes a base plate, an anti-settlement unit on the inner side of the base plate, an anti-deviation unit on the top surface of the base plate, and a fixing unit on the inner side of the anti-deviation unit. The anti-settlement unit includes an adjusting box, which is fixedly connected to the bottom surface of the base plate. A fixing cone is fixedly connected to the bottom surface of the adjusting box. A threaded rod is threadedly connected to the inner side of the top surface of the adjusting box. One end of the threaded rod extends to the inner side of the adjusting box and is threadedly connected to a meshing moving block. A guide rod is rotatably connected to the inner side of the meshing moving block. This invention, through the cooperation of the adjusting box, fixing cone, threaded rod, meshing moving block, guide rod, limiting rod, and guide groove, limits the installation of the concrete pipe pile, thus preventing settlement of the concrete pipe pile on the soft soil foundation.
[0004] Although the aforementioned limiting structure of the pipe pile can play a certain role in preventing settlement, the structure is relatively complex, the production and assembly are labor-intensive, and the production investment is also large, which is not conducive to its widespread use. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a concrete pipe pile suitable for construction on soft soil foundations. It features a simple structure, ease of use, convenient production and assembly, low production investment, and is conducive to widespread use. It also optimizes the support effect of the pipe pile. This solves the problem that although the limiting structure of existing pipe piles can play a certain role in preventing settlement, the structure is relatively complex, the production and assembly are laborious, and the production investment is large, which is not conducive to widespread use.
[0006] To achieve the above objectives, this application provides the following technical solution: a concrete pipe pile suitable for construction on soft soil foundation, comprising a soft soil foundation, a pile body slidably inserted inside the soft soil foundation, a support plate slidably sleeved on the outer circumferential surface of the pile body, the bottom surface of the support plate contacting the upper surface of the soft soil foundation, a sleeve fixedly connected to the upper surface of the support plate, the inner wall of the sleeve slidably sleeved with the outer circumferential surface of the pile body, and equidistantly arranged cross-shaped insertion holes provided inside the support plate, with a cross-shaped insertion plate slidably inserted inside the cross-shaped insertion holes.
[0007] The above solution addresses the issue that while existing pipe pile limiting structures can provide some anti-settlement effect, their complex structure makes production and assembly labor-intensive and requires significant investment, hindering widespread adoption. By incorporating support plates and sleeves to form a support structure, the support plates create a larger contact area between the support structure and the soft soil foundation, while the sleeves create a larger contact area between the support structure and the pile body. This optimizes the support effect on the pile body, effectively preventing settlement or displacement in the soft soil foundation and improving pile stability. Furthermore, the inclusion of cross-shaped inserts further enhances the stability of the support structure and optimizes the anti-displacement effect. The simpler support structure also facilitates production and assembly, requires less investment, and is conducive to widespread adoption.
[0008] Furthermore, the support plate is circular, and the cross-shaped insertion hole is arranged in a ring.
[0009] The above scheme ensures that the circular support plate maximizes the contact area between the support plate and the soft soil foundation, thereby improving the stability of the support. The uniformly distributed cross-shaped holes in a ring enhance the symmetry and stress uniformity of the overall structure. In addition, the circular support plate is easier to construct and install.
[0010] Furthermore, the bottom of the cross-shaped insert plate has a pointed conical structure.
[0011] With the above scheme, the contact area between the cross-shaped insert plate and the soil in the soft soil foundation is larger, which can strengthen the support plate, prevent the support plate from shifting, optimize the anti-shifting effect of the pile, and the cross-shaped insert plate with a pointed cone structure at the bottom can penetrate the soft soil foundation more easily to reach deeper soil layers, thereby increasing the support force.
[0012] Furthermore, a top plate is fixedly connected to the upper surface of the cross-shaped insert plate, and equidistant positioning rods are fixedly connected to the upper surface of the support plate. The outer circumferential surface of the positioning rod is slidably inserted into the top plate through a slot opened inside the top plate, and a first nut is threadedly connected to the outer circumferential surface of the positioning rod.
[0013] The above method uses a positioning rod and a first nut to position the top plate, which in turn positions the cross plate, facilitating its installation and disassembly.
[0014] Furthermore, the top end of the sleeve is threaded with a bolt, and the outer circumferential surface of the bolt is slidably inserted into the pile body through a slot opened inside the pile body.
[0015] The above method uses bolts to fix the sleeve and the pile body together, which facilitates the installation and laying of the sleeve.
[0016] Furthermore, a second nut is threaded onto the outer circumference of the bolt.
[0017] Through the above solution, the second nut plays a role in preventing the bolt from loosening, avoiding the bolt from easily falling off, and improving the stability of the connection between the sleeve and the pile.
[0018] Furthermore, the inner wall of the sleeve is fixedly connected with equidistant limiting plates, and the outer wall of the pile body is provided with equidistant limiting grooves. The limiting plates are slidably connected to the pile body through the limiting grooves.
[0019] The above scheme restricts the sleeve and support plate, preventing relative rotation between the sleeve and the pile, improving the stability of the connection between the pile and the sleeve, and thus optimizing the limiting effect of the sleeve and support plate on the pile.
[0020] Furthermore, the bottom surface of the support plate is fixedly connected with equidistantly arranged reinforcing cones.
[0021] The above-mentioned solution effectively prevents the support plate from rotating and shifting, improves the stability of the support plate, and further optimizes the anti-shifting effect of the pile.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This concrete pipe pile, suitable for construction on soft soil foundations, features a simple structure, ease of use, and convenient production and assembly. It requires minimal production investment, facilitating widespread adoption. By incorporating a support plate and sleeve, a support structure is formed. The support plate ensures a large contact area between the support structure and the soft soil foundation, while the sleeve ensures a large contact area between the support structure and the pile body. This optimizes the support effect on the pile body, effectively preventing settlement or displacement of the pile in soft soil foundations and improving pile stability. The inclusion of a cross-shaped insert further enhances the stability of the support structure and optimizes the anti-displacement effect of the pile body. This design solves the problems of existing pipe piles having complex limiting structures, requiring significant effort in production and assembly, and incurring substantial production investment, thus hindering widespread adoption.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment describes a concrete pipe pile suitable for construction on soft soil foundations, comprising a soft soil foundation 1, a pile body 2 slidably inserted inside the soft soil foundation 1, a support plate 3 slidably sleeved on the outer circumferential surface of the pile body 2, the bottom surface of the support plate 3 contacting the upper surface of the soft soil foundation 1, a sleeve 4 fixedly connected to the upper surface of the support plate 3, the inner wall of the sleeve 4 slidably sleeved on the outer circumferential surface of the pile body 2, and a cross-shaped insertion hole 5 equidistantly arranged inside the support plate 3, with a cross-shaped insertion plate 6 slidably inserted inside the cross-shaped insertion hole 5.
[0033] Please see Figure 1 , Figure 2 and Figure 4 The support plate 3 is circular, and the cross-shaped insertion holes 5 are arranged in a ring. The circular support plate 3 ensures that the contact area between the support plate 3 and the soft soil foundation 1 is maximized, thereby improving the support stability. The uniformly distributed cross-shaped insertion holes 5 enhance the symmetry and stress uniformity of the overall structure. In addition, the circular support plate 3 is easier to construct and install.
[0034] Please see Figure 2 The bottom of the cross-shaped insert plate 6 has a pointed cone structure, which increases the contact area between the cross-shaped insert plate 6 and the soil in the soft soil foundation 1, thereby reinforcing the support plate 3, preventing the support plate 3 from shifting, and optimizing the anti-shifting effect of the pile body 2. The cross-shaped insert plate 6 with a pointed cone structure at the bottom can penetrate the soft soil foundation 1 more easily and reach deeper soil layers, thereby increasing the support force.
[0035] Please see Figure 1 and Figure 2A top plate 7 is fixedly connected to the upper surface of the cross-shaped insert plate 6, and a positioning rod 8 is fixedly connected to the upper surface of the support plate 3. The outer circumferential surface of the positioning rod 8 is slidably inserted into the top plate 7 through a slot opened inside the top plate 7. A first nut 9 is threadedly connected to the outer circumferential surface of the positioning rod 8. The top plate 7 is installed and positioned by the positioning rod 8 and the first nut 9, thereby installing and positioning the cross-shaped insert plate 6, which facilitates the installation and disassembly of the cross-shaped insert plate 6.
[0036] Please see Figure 1 , Figure 2 and Figure 3 The top of the sleeve 4 is threaded with a bolt 10. The outer circumferential surface of the bolt 10 slides into the pile body 2 through a slot opened inside the pile body 2. The bolt 10 fixes the sleeve 4 and the pile body 2, which facilitates the installation and laying of the sleeve 4.
[0037] Please see Figure 3 The outer circumferential surface of the bolt 10 is threaded with a second nut 11. The second nut 11 serves to prevent the bolt 10 from loosening, avoid the bolt 10 from easily falling off, and improve the stability of the connection between the sleeve 4 and the pile body 2.
[0038] Please see Figure 3 and Figure 5 The inner wall of the sleeve 4 is fixedly connected with equidistant limiting plates 12, and the outer wall of the pile body 2 is provided with equidistant limiting grooves 13. The limiting plates 12 are slidably connected to the pile body 2 through the limiting grooves 13, which restricts the sleeve 4 and the support plate 3, prevents relative rotation between the sleeve 4 and the pile body 2, improves the stability of the connection between the pile body 2 and the sleeve 4, and optimizes the limiting effect of the sleeve 4 and the support plate 3 on the pile body 2.
[0039] Please see Figure 4 The bottom surface of the support plate 3 is fixedly connected with equidistant reinforcing cones 14. The reinforcing cones 14 can effectively prevent the support plate 3 from rotating and shifting, improve the stability of the support plate 3, and further optimize the anti-shifting effect of the pile body 2.
[0040] This embodiment presents a concrete pipe pile suitable for construction on soft soil foundations. It features a simple structure, ease of use, convenient production and assembly, low production investment, and is conducive to widespread adoption. By setting up a support plate 3 and a sleeve 4, a support structure is formed. The support plate 3 ensures a large contact area between the support structure and the soft soil foundation 1, and the sleeve 4 ensures a large contact area between the support structure and the pile body 2. This optimizes the support effect on the pile body 2, effectively preventing settlement or displacement of the pile body 2 in the soft soil foundation 1 and improving the stability of the pile body 2. The addition of a cross-shaped insert plate 6 further enhances the stability of the support structure and optimizes the anti-displacement effect of the pile body 2. This solves the problems of existing pipe piles having complex limiting structures, requiring significant effort during production and assembly, and incurring high production investment, which hinders their widespread adoption.
[0041] It should be noted that the support plate 3 and the sleeve 4 are integrally formed.
[0042] The working principle of the above embodiments is as follows:
[0043] When reinforcement of the pipe pile is required, the support structure consisting of the support plate 3 and the sleeve 4 is fitted onto the pile body 2. Bolts 10 and the second nut 11 are used to connect and fix the sleeve 4 to the pile body 2. Then, the cross plate 6 is inserted into the soft soil foundation 1 through the cross hole 5. Finally, the top plate 7 and the cross plate 6 are fixed by the positioning rod 8 and the first nut 9. When the pile body 2 is subjected to vertical or horizontal loads, the support structure consisting of the support plate 3 and the sleeve 4 can effectively distribute and bear these loads, preventing the pile body 2 from settling or shifting in the soft soil foundation 1. The support plate 3 promotes a large contact area between the support structure and the soft soil foundation 1, and the sleeve 4 promotes a large contact area between the support structure and the pile body 2, thereby optimizing the support effect of the pile body 2. The cross plate 6 has a larger contact area with the soil in the soft soil foundation 1, which can reinforce the support plate 3, prevent the support plate 3 from shifting, and optimize the anti-shifting effect of the pile body 2.
