Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a support pile wall for prestressed concrete piles. Background Technology

[0002] Prestressed concrete piles are pile foundations used in civil engineering. They are mainly composed of prestressed concrete pipe piles, which are slender tubular members with cross-sectional dimensions much smaller than their length. Prestressed concrete piles have the characteristics of high bearing capacity, good stability, and small settlement value. They can also be constructed using mechanized methods, which improves the construction progress. Therefore, they are a common type of foundation construction in modern construction.

[0003] In actual construction, to ensure the safety of prestressed concrete pile construction, retaining pile walls are generally erected. These retaining pile walls are mostly composed of multiple retaining piles forming a protective wall. However, the existing technology has the following technical problems and drawbacks: when constructing the retaining pile wall, the positioning of the retaining piles at the bottom of the retaining pile wall is not clear. When the retaining piles are installed on the retaining pile wall, the phenomenon of unstable displacement of the retaining piles during pouring is prone to occur, which directly affects the service strength of the retaining pile wall.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] This utility model provides a support pile wall for prestressed concrete piles. The first technical problem to be solved is that the positioning of the support piles at the bottom of the support pile wall is not clear. When the support piles are installed on the support pile wall, the phenomenon of unstable displacement of the support piles during pouring is easy to occur.

[0006] This application provides the following technical solution: A retaining wall for prestressed concrete piles, comprising: The base plate is provided with multiple positioning grooves; An elastic limiting body is provided on the base plate. At least two elastic limiting bodies are provided on the base plate for each positioning groove, and each elastic limiting body is arranged at intervals along the circumference of the positioning groove. Each support pile is inserted into a corresponding positioning groove at its bottom, and each elastic limiting body elastically abuts against the periphery of the corresponding support pile. The first guard rod extends along the arrangement direction of each support pile, and the first guard rod is connected to multiple support piles respectively. Multiple first guard rods are arranged at intervals along the height direction of the support piles. The second guard rod extends along the height direction of the support pile and is connected to a plurality of first guard rods arranged in sequence.

[0007] Optionally, the elastic limiting body includes a positioning plate and an elastic element; The positioning plate is at least partially located in the positioning groove; The elastic element abuts against the positioning plate and the base plate at both ends, respectively. With the support pile inserted into the positioning groove, the elastic element is in a compressed state, and the positioning plate abuts against the peripheral wall of the support pile.

[0008] Optionally, the sidewall of the positioning groove is provided with a recessed groove and a movable groove provided on the bottom wall of the recessed groove; A movable rod is vertically connected to the positioning plate; The movable rod is slidably inserted into the movable slot; The elastic element is sleeved on the movable rod, and both ends of the elastic element abut against the bottom wall of the sinkhole and the positioning plate, respectively.

[0009] Optionally, each of the positioning grooves may have at least one elastic limiting body provided on each of its opposite sides.

[0010] Optionally, the upper surface of the positioning plate facing the support pile is provided with a guide slope; In the direction from bottom to top, the guide slope gradually extends and tilts away from the center line of the positioning groove.

[0011] Optionally, horizontal through slots are provided on the support piles; The first support rod is configured to pass through horizontal slots on multiple support piles.

[0012] Optionally, the first support rod is provided with external threads at both ends; The first locking cap is located at both ends of the first support rod and is threadedly connected to the first support rod.

[0013] Optionally, a vertical through slot is provided on the first support rod; The second guard rod is provided with vertical through slots on multiple first guard rods.

[0014] Optionally, the second support rod is provided with external threads at both ends; The second locking cap is located at both ends of the second support pile and is threadedly connected to the second support rod.

[0015] Optionally, a plurality of reinforcing rods are provided inside the support pile, and each reinforcing rod is arranged sequentially along the length direction of the support pile, and the reinforcing rod extends along a direction perpendicular to the length direction of the support pile; Connecting blocks are provided on opposite sides at both ends of the support pile, and the connecting blocks connect two adjacent reinforcing rods; The concrete of the support piles covers each of the reinforcing rods.

[0016] By adopting the above technical solution, this application has the following beneficial effects: The prestressed concrete pile support wall provided in this application uses positioning grooves set on the base plate and at least two elastic limiting bodies arranged sequentially and spaced apart along the circumference of each positioning groove. When the bottom of the support pile is inserted into the corresponding positioning groove, each elastic limiting body elastically abuts against the circumferential wall of the corresponding support pile. This can effectively position and limit the support pile, effectively solving the technical problems of unclear positioning of the support pile at the bottom of the support pile wall and unstable pouring deviation when the support pile is installed on the support pile wall, thus improving the service strength of the support pile wall.

[0024] like Figures 1 to 4 As shown in the figure, this application provides a support wall for prestressed concrete piles, including a base plate 1, elastic limiting bodies, support piles 7, first support rods 4, and second support rods 3. The base plate 1 is provided with multiple positioning grooves 2. The elastic limiting bodies are disposed on the base plate 1. At least two elastic limiting bodies are provided on the base plate 1 corresponding to each positioning groove 2, and the elastic limiting bodies are sequentially spaced along the circumference of the positioning groove 2. The bottom of each support pile 7 is inserted into the corresponding positioning groove 2, and each elastic limiting body elastically abuts against the circumferential wall of the corresponding support pile 7. The first support rods 4 extend along the arrangement direction of each support pile 7, and the first support rods 4 are respectively connected to multiple support piles 7. The multiple first support rods 4 are sequentially spaced along the height direction of the support piles 7. The second support rods 3 extend along the height direction of the support piles 7, and the second support rods 3 are respectively connected to the sequentially arranged multiple first support rods 4.

[0025] The prestressed concrete pile support wall provided in this application uses positioning grooves 2 set on the base plate 1 and at least two elastic limiting bodies arranged sequentially and spaced along the circumference of each positioning groove 2. When the bottom of the support pile 7 is inserted into the corresponding positioning groove 2, each elastic limiting body elastically abuts against the circumferential wall of the corresponding support pile 7. This can play a good role in positioning and limiting the support pile 7, effectively solving the technical problem that the bottom of the support pile 7 wall is not clearly positioned for the support pile 7, and that the support pile 7 is prone to unstable pouring deviation when it is set on the support pile 7 wall, thus improving the strength of the support pile 7 wall.

[0026] Meanwhile, the first support rod 4 extends along the arrangement direction of each support pile 7 and connects to multiple support piles 7 respectively. Multiple first support rods 4 are sequentially spaced along the height direction of the support piles 7. The second support rod 3 extends along the height direction of the support piles 7 and connects to the sequentially arranged first support rods 4 respectively, further enhancing the structural stability of the entire support pile 7 wall, enabling it to better withstand external pressure and forces, ensuring construction safety and the positional stability of the support piles 7. Furthermore, multiple reinforcing rods 10 are installed within the support piles 7, sequentially arranged along their length and extending perpendicular to their length direction. Connecting blocks 11 are installed on opposite sides at both ends of the support piles 7, connecting two adjacent reinforcing rods 10. The concrete of the support piles 7 covers each reinforcing rod 10, further improving the strength and bearing capacity of the support piles 7 themselves, thereby enhancing the performance of the entire prestressed concrete pile support wall.

[0027] In some possible implementations, the elastic limiting body includes a positioning plate 14 and an elastic element 15. The positioning plate 14 is at least partially located in the positioning groove 2, and the two ends of the elastic element 15 abut against the positioning plate 14 and the base plate 1, respectively. When the support pile 7 is inserted into the positioning groove 2, the elastic element 15 is in a compressed state, and the positioning plate 14 abuts against the peripheral wall of the support pile 7. This design allows the elastic limiting body to adaptively adjust according to the insertion of the support pile 7, providing stable and reliable positioning and limiting for the support pile 7 through the compression of the elastic element 15 and the abutment of the positioning plate 14.

[0028] In some possible implementations, the sidewall of the positioning groove 2 has a recessed groove 16 and a movable groove 12 disposed on the bottom wall of the recessed groove 16, and a movable rod 13 is vertically connected to the positioning plate 14. The movable rod 13 is slidably inserted through the movable groove 12, and the elastic element 15 is sleeved on the movable rod 13, with both ends of the elastic element 15 abutting against the bottom wall of the recessed groove 16 and the positioning plate 14, respectively. This structure further enhances the flexibility and stability of the elastic limiting body. The sliding of the movable rod 13 in the movable groove 12 allows the positioning plate 14 to move more smoothly with the compression and extension of the elastic element 15. At the same time, the elastic element 15 sleeved on the movable rod 13 can better ensure the directional stability of its compression and extension, thereby more accurately positioning and limiting the support pile 7.

[0029] In some possible implementations, each of the positioning slots 2 is provided with at least one elastic limiting body on each of its opposite sides. This arrangement enables the support pile 7 to be positioned and limited from multiple directions, ensuring that the position of the support pile 7 within the positioning slot 2 is more stable and reducing the possibility of displacement.

[0030] In some possible implementations, the upper surface of the positioning plate 14 facing the support pile 7 is provided with a guide slope 17, which gradually extends away from the centerline of the positioning groove 2 in an upward direction. The design of the guide slope 17 facilitates the insertion of the support pile 7 into the positioning groove 2. When the bottom of the support pile 7 contacts the guide slope 17, the positioning plate 14 can be smoothly pushed to both sides along the slope, making it easier for the support pile 7 to be inserted into the positioning groove 2, thus improving the convenience and efficiency of construction.

[0031] In some possible implementations, horizontal through-slots 6 are formed on the support piles 7, and the first support rod 4 is disposed through the horizontal through-slots 6 on multiple support piles 7. The first support rod 4 can stably connect multiple support piles 7, and the positioning effect of the horizontal through-slots 6 ensures that the connection position between the first support rod 4 and the support piles 7 is accurate, thereby enhancing the structural stability of the entire support pile 7 wall in the horizontal direction.

[0032] In some possible implementations, the first support rod 4 has external threads at both ends, and the first locking cap 8 is located at both ends of the first support rod 4 and threadedly connected to the first support rod 4. The cooperation of the external threads and the first locking cap 8 allows for easy installation and disassembly of the first support rod 4. Furthermore, the position of the first locking cap 8 can be adjusted according to actual needs, thereby adjusting the tightness of the connection between the first support rod 4 and the support pile 7, ensuring the reliability and stability of the connection.

[0033] In some possible implementations, the first support rod 4 has a vertical through slot 9, and the second support rod 3 is provided through the vertical through slots 9 on multiple first support rods 4. This structure allows the second support rod 3 to connect with multiple first support rods 4, further enhancing the overall structural integrity of the entire support pile 7 wall in both vertical and horizontal directions, enabling it to better withstand external forces from different directions.

[0034] In some possible implementations, the second support rod 3 has external threads at both ends, and the second locking cap 5 is located at both ends of the second support pile 7 and threadedly connected to the second support rod 3. Similar to the connection method of the first support rod 4, the engagement of the external threads at both ends of the second support rod 3 and the second locking cap 5 facilitates the installation and disassembly of the second support rod 3, as well as the adjustment of the connection tightness, ensuring a stable and reliable connection between the second support rod 3 and the first support rod 4.

[0035] In some possible implementations, a plurality of reinforcing rods 10 are provided within the support pile 7, with each reinforcing rod 10 arranged sequentially along the length direction of the support pile 7 and extending perpendicular to the length direction of the support pile 7. The installation of the reinforcing rods 10 can significantly improve the strength and bending resistance of the support pile 7 itself, making it less prone to deformation and damage when subjected to external pressure and force, thereby ensuring the performance and service life of the entire support pile 7 wall.

[0036] In some possible implementations, connecting blocks 11 are respectively provided on opposite sides at both ends of the support pile 7, and the connecting blocks 11 connect two adjacent reinforcing rods 10. The function of the connecting blocks 11 is to connect adjacent reinforcing rods 10 into a whole, further enhancing the synergistic effect between the reinforcing rods 10 and improving the stability and strength of the internal structure of the support pile 7.

[0037] In some possible implementations, the concrete of the support pile 7 covers each of the reinforcing rods 10. This concrete covering not only protects the reinforcing rods 10 from environmental erosion and extends their service life, but also allows the reinforcing rods 10 and the concrete to work together more effectively, jointly bearing external forces and further enhancing the load-bearing capacity and overall performance of the support pile 7.

[0038] The preferred embodiments disclosed above are merely illustrative of this application. The preferred embodiments do not exhaustively describe modifications and variations. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application.
