Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe pile technology, and in particular to a pipe pile with reinforcing ribs. Background Technology
[0002] In modern engineering construction, pipe piles, as a key component of foundation structures, are widely used in buildings, bridges, ports, municipal engineering, and other projects. They play a crucial role in transferring the loads of the superstructure to the foundation. With the continuous expansion of project scale and the increasing complexity of geological conditions, higher requirements are placed on the bearing capacity, deformation resistance, stability, and durability of pipe piles. Traditional pipe piles, due to their simple structural design, are prone to problems such as relative displacement between inner and outer layers, local stress concentration, and insufficient shear resistance when subjected to axial loads, eccentric loads, or complex geological stresses. This leads to premature failure of the pipe piles, affecting the safety and service life of the project. Utility Model Content
[0003] The purpose of this utility model is to provide a pipe pile with reinforcing ribs. By symmetrically distributing fixed reinforcing ribs that support the outer wall of the inner pipe, the pipe pile works in synergy with the outer layer of the pipe pile to enhance the axial load transmission capacity of the pipe pile and prevent relative displacement between the inner and outer layers. The triangular reinforcing ribs reinforce the inner wall of the inner pipe with a triangular structure, disperse the eccentric load stress, and improve the deformation resistance. The stabilizing connecting ribs form triangular supports at the connection between the triangular reinforcing ribs and the inner pipe, enhancing the structural rigidity and integrity, improving seismic performance, significantly improving the compressive, shear, and tensile strength of the pipe pile, ensuring uniform stress distribution and good stability, and effectively extending its service life.
[0004] To achieve the above objectives, a reinforced pipe pile is provided, comprising: an outer layer of the pipe pile and a fixing assembly. A supporting inner tube is fixedly connected to the inner surface of the outer layer of the pipe pile. Reinforcing ribs are fixedly connected to both the front and rear sides of the outer wall of the supporting inner tube. Triangular reinforcing ribs are fixedly connected to the inner wall of the supporting inner tube. Stabilizing connecting ribs are fixedly connected to both the inner and outer surfaces of the triangular reinforcing ribs. This multi-layered fixed connection forms an integral load-bearing structure, improving the load-bearing capacity and structural stability of the pipe pile, and enhancing its collaborative working efficiency.
[0005] According to the aforementioned reinforced pipe pile, the stabilizing connecting bar is located at the connection between the triangular reinforcing bar and the supporting inner tube, and the cross-section of the stabilizing connecting bar is triangular. The triangular cross-section enhances the connection strength, disperses stress at the connection, prevents loosening, and ensures that the triangular reinforcing bar and the supporting inner tube work together to bear the load.
[0006] According to the aforementioned reinforced pipe pile, the triangular reinforcing ribs are evenly distributed on the inner wall of the supporting inner pipe, and the number of triangular reinforcing ribs corresponds to the number of pipes in the pile. This even distribution and corresponding quantity ensures balanced stress distribution, avoids localized overload, and improves the overall deformation resistance of the supporting inner pipe.
[0007] According to the aforementioned reinforced pipe pile, the fixed reinforcing ribs are arranged in a circumferential array on the outer wall of the supporting inner pipe. The circumferential array forms a ring reinforcement, enhancing the radial bearing capacity of the supporting inner pipe and effectively resisting deformation caused by external pressure.
[0008] According to the aforementioned reinforced pipe pile, the fixing component is located inside the outer layer of the pipe pile. The fixing component includes an abutment fitting plate, precast reinforcing bars, and a connecting sleeve. Precast reinforcing bars are provided around the inner perimeter of the outer layer of the pipe pile. Abutment fitting plates are snapped into the upper and lower sides of the outer layer of the pipe pile. A connecting sleeve is provided on the lower surface of the outer layer of the pipe pile. The multi-component coordinated fixing strengthens the outer structure of the pipe pile, improves overall stability, and facilitates installation and connection.
[0009] According to the aforementioned reinforced pipe pile, the precast reinforcing bars are located between the inner supporting pipe and the outer layer of the pipe pile, and are positioned above the connecting sleeve. This layout enhances the connection between the two layers, transfers loads more efficiently, provides structural support for the connecting sleeve, and improves the joint strength.
[0010] According to the aforementioned reinforced pipe pile, the dimensions of the connecting sleeve and the precast reinforcing steel are correspondingly set, and the abutting fitting plate is located on the outer wall of the supporting inner pipe. The dimensional correspondence ensures precise and stable connection, and the abutting fitting plate enhances the fit between the supporting inner pipe and the outer layer, improving overall integrity.
[0011] The positions of the fixed reinforcing bars and the precast reinforcing bars are staggered, and the dimensions of the abutting interlocking plate are adapted to the dimensions of the supporting inner tube. This staggered arrangement avoids stress superposition, and the size adaptation ensures a tight fit, thereby improving the shear and compressive strength of the pipe pile.
[0012] The above-mentioned solution has the following beneficial effects:
[0013] This utility model incorporates fixed reinforcing ribs, triangular reinforcing ribs, and stabilizing connecting ribs. The fixed reinforcing ribs, symmetrically distributed to support the outer wall of the inner tube, work synergistically with the outer layer of the pipe pile to enhance the axial load transfer capacity of the pipe pile and prevent relative displacement between the inner and outer layers. The triangular reinforcing ribs reinforce the inner wall of the inner tube with a triangular structure, dispersing eccentric load stress and improving deformation resistance. The stabilizing connecting ribs form triangular supports at the connection between the triangular reinforcing ribs and the inner tube, enhancing structural rigidity and integrity, improving seismic performance, significantly increasing the compressive, shear, and tensile strength of the pipe pile, ensuring uniform stress distribution and excellent stability, and effectively extending its service life.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-4 This utility model discloses a reinforced pipe pile, comprising: an outer layer 1 and a fixing assembly. A supporting inner tube 4 is fixedly connected to the inner surface of the outer layer 1. The supporting inner tube 4, through its fixed connection with the outer layer 1, provides radial support to the entire pipe pile, enhancing its compressive strength and ensuring that the outer and inner layers work together under stress. Reinforcing ribs 5 are fixedly connected to both the front and rear sides of the outer wall of the supporting inner tube 4. These reinforcing ribs 5 are symmetrically arranged along the front and rear sides of the outer wall of the supporting inner tube 4, working together with the outer layer 1 to effectively... The inner wall of the inner support tube 4 is fixedly connected with triangular reinforcing ribs 7. The triangular reinforcing ribs 7, with their unique triangular structure, significantly enhance the deformation resistance of the inner support tube 4 through their fixed connection with the inner wall of the inner support tube 4. Especially when subjected to eccentric loads, they can effectively disperse stress and maintain the overall structural integrity of the pipe pile. Stable connecting ribs 8 are fixedly connected to both the inner and outer surfaces of the triangular reinforcing ribs 7.
[0024] The stabilizing connecting ribs 8 are located at the connection between the triangular reinforcing ribs 7 and the supporting inner tube 4, and their cross-section is triangular. This structural design not only enhances the rigidity of the triangular reinforcing ribs 7 themselves, but also further strengthens the connection between the triangular reinforcing ribs 7 and the supporting inner tube 4, so that the two form a unified load-bearing system when under stress, thereby improving the seismic performance of the pipe pile. The triangular reinforcing ribs 7 are evenly distributed on the inner wall of the supporting inner tube 4, and the number of triangular reinforcing ribs 7 is set in a corresponding manner. The evenly distributed triangular reinforcing ribs 7 ensure that the inner wall of the supporting inner tube 4 is subjected to uniform stress, avoids local stress concentration, and ensures that the pipe pile can maintain stable mechanical properties under various working conditions. The corresponding arrangement of the number ensures the symmetry and balance of the structure. The fixed reinforcing ribs 5 are arranged in a circumferential array on the outer wall of the supporting inner tube 4. The circumferential array of fixed reinforcing ribs 5 forms a ring support system on the outer wall of the supporting inner tube 4, which effectively resists the circumferential deformation of the pipe pile. At the same time, they are staggered with the precast steel bars 3 to jointly construct a three-dimensional reinforcement network, thereby improving the overall strength and shear resistance of the pipe pile.
[0025] The fixing assembly is located inside the outer layer 1 of the pipe pile. The fixing assembly includes an abutment plate 2, precast steel bars 3, and a connecting sleeve 6. As a key connecting structure inside the pipe pile, the fixing assembly, through the synergistic action of the abutment plate 2, precast steel bars 3, and connecting sleeve 6, firmly connects the various parts of the pipe pile together, ensuring that the pipe pile does not disintegrate during transportation, construction, and use, thus guaranteeing structural safety. Precast steel bars 3 are arranged around the inner perimeter of the outer layer 1, working together with the concrete of the outer layer 1 to improve the tensile strength and crack resistance of the pipe pile. Especially when subjected to horizontal loads or seismic forces, they effectively restrain the concrete. To prevent soil cracking and extend the service life of the pipe piles, the outer layer 1 of the pipe pile is fitted with abutment plates 2 on both the upper and lower sides. These abutment plates 2 are tightly connected to the outer layer 1 via a snap-fit mechanism, providing precise positioning and a reliable force transmission path during pipe pile connection. Simultaneously, they protect the pipe pile ends from damage, ensuring the sealing and integrity of the pipe pile joint. A connecting sleeve 6 is provided on the lower surface of the outer layer 1. The connecting sleeve 6 provides a standardized connection interface for pipe pile extension. Its dimensions correspond to the precast steel bars 3, ensuring accurate connection between adjacent pipe piles and enabling the pipe piles to form a continuous load-bearing structure after extension, meeting the project's requirements for pipe pile length. The precast steel... The reinforcing bar 3 is located between the inner supporting tube 4 and the outer layer 1 of the pipe pile. The precast reinforcing bar 3 is positioned above the connecting sleeve 6. This arrangement of the precast reinforcing bar 3 effectively transmits the shear force between the inner supporting tube 4 and the outer layer 1 of the pipe pile, while simultaneously forming a reinforced zone above the connecting sleeve 6, improving the strength and rigidity of the pipe pile joint and ensuring smooth load transfer. The dimensions of the connecting sleeve 6 and the precast reinforcing bar 3 are correspondingly set, ensuring that the precast reinforcing bar 3 can be smoothly inserted into the connecting sleeve 6, forming a reliable mechanical connection. This allows adjacent pipe piles to work together under stress, avoiding stress concentration and structural damage caused by improper connection. The contact plate 2 is located within the inner supporting tube 4. The outer wall of the pipe pile has the fixed reinforcing ribs 5 and the precast steel bars 3 staggered. The tight fit between the contact plate 2 and the outer wall of the inner support tube 4 enhances the stability of the inner support tube 4. The staggered arrangement of the fixed reinforcing ribs 5 and the precast steel bars 3 allows them to play a reinforcing role in different directions, forming complementary mechanical properties and improving the comprehensive bearing capacity of the pipe pile. The size of the contact plate 2 is compatible with the size of the inner support tube 4. This compatibility ensures that the contact plate 2 can completely wrap the end of the inner support tube 4, providing sufficient contact area during pipe pile connection, so that the load can be evenly transmitted, avoiding damage caused by excessive local stress, and ensuring the reliability of the pipe pile connection.
[0026] Working principle: First, the inner support tube 4 is fixed to the inner surface of the outer layer 1 of the pipe pile, ensuring a tight connection between the two. At this time, the inner support tube 4 provides radial support for the pipe pile and together with the outer layer 1 of the pipe pile, forms the foundation structure. Reinforcing ribs 5 are symmetrically installed on the front and rear sides of the outer wall of the inner support tube 4 and arranged in a circular array along the circumference of the outer wall to form a ring support system, enhancing the deformation resistance of the pipe pile. Triangular reinforcing ribs 7 are uniformly welded to the inner wall of the inner support tube 4, their number corresponding to the number of the reinforcing ribs 5. Simultaneously, the inner and outer surfaces of the triangular reinforcing ribs 7 are... Stable connecting ribs 8 (triangular cross-section) are welded at the connection of the inner supporting tube 4 to further strengthen the structure and improve seismic performance. Precast steel bars 3 are evenly arranged around the inner perimeter of the outer layer 1 of the pipe pile, positioned between the inner supporting tube 4 and the outer layer 1 of the pipe pile, and staggered with the fixing reinforcing ribs 5. The precast steel bars 3 and the concrete of the outer layer 1 of the pipe pile work together to improve the tensile strength and crack resistance of the pipe pile. The abutment fitting plates 2 are snapped onto the upper and lower sides of the outer layer 1 of the pipe pile to ensure that their dimensions are adapted to the outer wall of the inner supporting tube 4 and tightly wrap the inner supporting tube 4. At the end of pipe 4, a positioning and force transmission path is provided for the connection of the pipe pile. A connecting sleeve 6 is opened on the lower surface of the outer layer 1 of the pipe pile, with its size corresponding to the precast steel bar 3. The connecting sleeve 6 is located below the precast steel bar 3, providing a standardized interface for subsequent pipe pile extension. The fixing components (abutment plate 2, precast steel bar 3, connecting sleeve 6) ensure the structural stability of the pipe pile during transportation and storage, preventing components from loosening or being damaged. The first section of the pipe pile is hoisted to the pile position and positioned by the abutment plate 2 to ensure vertical insertion into the soil. When extension is required... During the pipe pile construction, the precast steel bars 3 of the second pipe pile are aligned with the connecting sleeve 6 of the first pipe pile and inserted. A continuous load-bearing structure is formed through mechanical connection. The mating plates 2 of the upper and lower pipe piles fit tightly together to ensure uniform load transfer. Finally, the pipe pile construction is completed. After construction, the various components of the pipe pile work together to bear the load: the fixed reinforcing bars 5 and the triangular reinforcing bars 7 resist axial and radial loads, the precast steel bars 3 restrain concrete cracking, and the stabilizing connecting bars 8 enhance the seismic performance of the structure. Together, they ensure the safety and durability of the pipe pile under complex working conditions.
