Description

Technical Field

[0001] The utility model belongs to the technical field of pile connection structures, in particular to a pile connection structure of prefabricated pipe piles. Background Art

[0002] Prefabricated pipe piles are one of the commonly used pile foundation types in the construction industry and are generally used for foundation construction. A single prefabricated pipe pile is generally of fixed length, so when long piles are needed, multiple pipe piles are generally welded together and two pipe piles are generally welded on-site at the piling site, that is, the piles are connected.

[0003] There are also related technologies that use the threads on the connector to connect two sections of pipe piles, and apply adhesive on the end faces of the two sections of pipe piles to fix the connection with the threads. However, when the pipe piles are aligned, the end faces are coated with adhesive, and the pipe piles need to fit tightly, which will inevitably squeeze the adhesive and cause the adhesive to squeeze out from the joints, causing the adhesive to overflow. The adhesive overflowing from the joints needs to be removed during subsequent welding, which affects the welding efficiency. At the same time, if the adhesive on the surface of the pipe piles is not cleaned up, it will also affect the strength of the welding. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a prefabricated pipe pile connection structure, which, through the coordinated arrangement of a connecting head and a connecting seat, enables the device to improve the pull-out resistance of the existing prefabricated pipe piles, increase the pull-out bearing capacity, enhance the engineering safety and pile connection quality, and solve the problems in the above background.

[0006] Preferably, the connecting seat includes a first fixing column arranged in the fixing groove, and the top of the first fixing column is fixedly connected to the connecting groove.

[0007] Preferably, the connecting head comprises a second fixing column pre-buried at the bottom of the pile tail, and a cylindrical fixing block is fixedly connected to the bottom of the second fixing column, and the fixing block can be embedded in the connecting groove.

[0009] Preferably, the first fixing column and the pile head are integrally formed by epoxy resin mortar.

[0010] Preferably, the second fixing column and the pile tail are integrally formed by epoxy resin mortar.

[0011] Preferably, when the pile head and the pile tail are connected so that the epoxy resin fills the fixing groove and the excess epoxy resin flows on the inner wall of the pile, the compressive resistance can be exerted without affecting welding.

[0012] Preferably, the connecting seat and the connecting head are both made of metal.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model proposes a prefabricated pipe pile connection structure, which is arranged in coordination with a connecting head and a connecting seat, so that the device can improve the pull-out resistance of existing prefabricated pipe piles, improve the pull-out bearing capacity, enhance the project safety and pile connection quality, and can greatly improve the construction efficiency and quality of the pile foundation, reduce construction costs, and provide strong support for the development of the modern construction field.

[0019] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Combination Figure 1 , Figure 2 and Figure 3As shown, a prefabricated pipe pile connection structure includes a pile head 1 and a pile tail 2. The top of the pile head 1 is provided with a plurality of fixing grooves 3 in an annular shape, and a connection seat 4 is provided inside all the fixing grooves 3. The bottom of the pile tail 2 is provided with a plurality of connecting heads 5 matching the connection seat 4 in an annular shape. When all the connecting heads 5 are fully embedded in the connection seat 4, the top end surface of the pile head 1 and the bottom end surface of the pile tail 2 are in contact with each other. Specifically, a prefabricated pipe pile connection structure is intended to provide an efficient, stable and easy-to-operate connection method to meet the high requirements of the pile foundation structure in the modern construction field. This pile connection structure is mainly composed of a pile head 1 and a pile tail 2, and a stable connection between piles is achieved through a unique connection method. The pile head 1 is one of the key parts of the pile connection structure, and its top is uniquely designed, with a plurality of fixing grooves 3 arranged in an annular shape. These fixing grooves 3 are not only precisely shaped, but also moderate in number, ensuring that sufficient connection points and stability can be provided when the pile head 1 is connected to the pile tail 2. Each fixing groove 3 is provided with a connection seat 4, which is made of high-strength material, has a solid structure, and has good wear resistance and corrosion resistance to ensure that it is not easily damaged during long-term use. The design of the pile tail 2 is also exquisite, and a number of connectors 5 are arranged in a ring at its bottom. These connectors 5 match the connection seat 4 on the pile head 1 to ensure accurate docking during connection. The connector 5 is also made of high-strength material, and the surface is specially treated to have good lubricity and wear resistance to reduce the friction resistance generated during the connection process and improve the connection efficiency. When the pile connection operation is performed, first align the bottom of the pile tail 2 with the top of the pile head 1, and then all the connectors 5 are embedded in the corresponding connection seat 4 one by one. When all the connectors 5 are fully embedded in the connection seat 4, the top end face of the pile head 1 and the bottom end face of the pile tail 2 will fit tightly to form a whole. At this time, the pile connection structure completes the connection between the piles. The advantages of this pile connection structure are that it is simple to operate, stable connection, and high efficiency. Through precise design and manufacturing, it is ensured that the connector 5 and the connector base 4 can be accurately docked, thereby avoiding safety hazards caused by loose connections. In addition, since the connector base 4 and the connector 5 are made of high-strength materials, the pile connection structure has a high bearing capacity and durability, and can meet the use requirements under various complex geological conditions. In practical applications, this prefabricated pipe pile connection structure can be widely used in the construction of infrastructure such as bridges, highways, railways, and ports. By using this pile connection structure, the construction efficiency and quality of the pile foundation can be greatly improved, the construction cost can be reduced, and strong support can be provided for the development of the modern construction field.

[0021] Combination Figure 2 and Figure 3 As shown, the connection seat 4 includes a first fixing column 41 disposed in the fixing groove 3, and the top of the first fixing column 41 is fixedly connected to the connection groove 42. Figure 2 and Figure 3 As shown, the connector 5 includes a second fixing column 51 embedded at the bottom of the pile tail 2, and a cylindrical fixing block 52 is fixedly connected to the bottom of the second fixing column 51, and the fixing block 52 can be embedded in the connecting groove 42. Specifically, the connecting seat 4 includes a first fixing column 41 arranged in the fixing groove 3. The first fixing column 41 is strong and stable, ensuring that the connecting seat 4 can be firmly fixed in the fixing groove 3 of the pile head 1. The top of the first fixing column 41 is fixedly connected with a connecting groove 42, which is a key part for the connecting seat 4 to connect with the connector 5 of the pile tail 2. The shape and size of the connecting groove 42 match the connector 5 to ensure that the connector 5 can be accurately embedded therein. The interior of the connecting groove 42 is designed with an appropriate gap so that when the connector 5 is embedded, it can accommodate the slight deviation caused by the slight deformation of the pile body or the construction error, thereby ensuring the smoothness and stability of the connection. The connector 5 includes a second fixing column 51 embedded at the bottom of the pile tail 2. The second fixing column 51 is closely connected to the bottom structure of the pile tail 2 to ensure its stability and bearing capacity. The bottom of the second fixed column 51 is fixedly connected with a cylindrical fixed block 52, and the diameter and length of the fixed block 52 match the connecting groove 42 to ensure that it can be smoothly embedded in the connecting groove 42. In the process of pile connection, the fixed block 52 plays a key role. When the bottom of the pile tail 2 is docked with the top of the pile head 1, the fixed block 52 will be accurately embedded in the connecting groove 42. Since the fixed block 52 is cylindrical, its surface has been specially treated and has good lubricity and wear resistance, which makes the embedding process smoother and reduces friction resistance. At the same time, the close fit between the fixed block 52 and the connecting groove 42 ensures the stability and reliability of the connection. When all the fixed blocks 52 of the connector 5 are fully embedded in the connecting groove 42, the top end face of the pile head 1 and the bottom end face of the pile tail 2 will fit closely to form a whole. At this time, the pile connection structure completes the connection between the piles. This connection method is not only simple to operate, but also has a stable connection, can withstand large tension and pressure, and meet the use requirements under various complex geological conditions.

[0022] Combination Figure 2 and Figure 3As shown, the opening of the connection groove 42 is provided with a hook 421 bent inward. Specifically, during the pile connection process, the fixing block 52 will be accurately embedded in the connection groove 42. Since the opening of the connection groove 42 is provided with a hook 421, when the fixing block 52 is fully embedded, the hook 421 will tightly hook the fixing block 52, thereby forming a stable connection structure. This connection method is not only simple to operate, but also has a stable connection, and can withstand large tension and pressure, ensuring that the connection between the piles is safe and reliable. In addition, the design of the hook 421 also has a certain degree of elasticity. During the connection process, if there is a slight deviation or misalignment between the fixing block 52 and the connection groove 42, the hook 421 can adapt to this deviation through its own elastic deformation, thereby ensuring the smooth connection. This design makes the pile connection structure have higher adaptability and fault tolerance, and improves construction efficiency and quality.

[0023] Combination Figure 1 , Figure 2 and Figure 3 As shown, the first fixing column 41 and the pile head 1 are integrally formed by epoxy resin mortar. Figure 1 , Figure 2 and Figure 3 As shown, the second fixing column 51 and the pile tail 2 are integrally formed by epoxy resin mortar. Specifically, the first fixing column 41 and the fixing groove 3 of the pile head 1 are integrally formed by epoxy resin mortar. This connection method ensures the close connection between the connecting seat 4 and the pile head 1, which not only improves the connection strength, but also enhances the stability of the entire pile connection structure. Epoxy resin mortar is a high-strength, high-viscosity material that can be tightly filled between the fixing groove 3 and the first fixing column 41 to form a seamless connection surface. This integrally formed connection method eliminates any looseness or gap between the connecting seat 4 and the pile head 1, thereby greatly improving the stability and reliability of the pile connection structure. The second fixing column 51 and the pile tail 2 are also integrally formed by epoxy resin mortar. This connection method forms a seamless, gap-free whole between the second fixing column 51 and the pile tail 2, thereby improving the stability and bearing capacity of the entire pile connection structure.

[0024] Combination Figure 1 , Figure 2 and Figure 3As shown, when the pile head 1 and the pile tail 2 are connected to fill the fixing groove 3 with epoxy resin and make the excess epoxy resin flow on the inner wall of the pipe pile, the compressive resistance can be exerted without affecting the welding. Specifically, during the connection process, epoxy resin mortar is used to fill the fixing groove 3. This high-strength, high-viscosity material can not only effectively fix the connection seat 4 and the connector 5 when filling the fixing groove 3, but also enhance the stability of the entire pile connection structure through its unique compressive resistance. At the same time, the filling method of epoxy resin mortar also ensures the tightness and reliability of the connection, avoiding looseness or gaps at the connection. In the process of filling the fixing groove 3, excess epoxy resin mortar will flow on the inner wall of the pipe pile. This design cleverly utilizes the fluidity and filling properties of epoxy resin mortar, which not only does not affect the welding process, but can further enhance the strength and stability of the inner wall of the pipe pile. The excess epoxy resin mortar forms a protective layer on the inner wall of the pipe pile, which can effectively resist erosion and damage from the external environment, thereby extending the service life of the pipe pile. In addition, this pile connection structure is also highly repeatable and standardized. Since the size and shape of the connection base 4 and the connection head 5 are standardized, the connection between different piles can be easily realized, which not only improves the construction efficiency, but also reduces the construction cost, and provides strong support for the development of the modern construction field.

[0025] Combination Figure 1 , Figure 2 and Figure 3 As shown, the connecting seat 4 and the connecting head 5 are both made of metal. Specifically, during the connection process, the pile head 1 and the pile tail 2 are butt-jointed through the connecting seat 4 and the connecting head 5. The connecting seat 4 and the connecting head 5 are both made of metal. The choice of this material not only ensures that the connecting seat 4 and the connecting head 5 have sufficient strength and durability, but also can meet the use requirements in various complex environments. The connecting seat 4 and the connecting head 5 made of metal not only ensure the strength and stability of the connection, but also make the entire pile connection structure have higher corrosion resistance and wear resistance. The choice of this material enables the pile connection structure to be used for a long time in various harsh environments, greatly extending its service life.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
