[0002] In the field of engineering pile foundation, prestressed pipe piles are widely used.

[0036] The following will describe in more detail a self-locking connection mechanism for pipe piles according to the present invention with reference to the accompanying drawings, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad knowledge for those skilled in the art and not as a limitation to the present invention.

[0037] In the description of this specification, "one embodiment" or "some embodiments" etc. mean that in one or more embodiments of this specification, specific features, structures or characteristics described in connection with that embodiment are included. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all of the embodiments", unless otherwise specifically emphasized in other ways.

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the accompanying drawings below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0039] The following refers to Figure 1-Figure 7 Describe the self-locking connection mechanism of the pipe pile according to the embodiment of the present invention.

[0040] The self-locking connection mechanism of the pipe pile according to the embodiment of the present invention, as Figure 1 shown, includes: a first pile body 1, a second pile body 2, a mounting assembly (not shown in the figure), and a connecting member 5. One of the mounting assemblies is fixedly installed on one end face of the first pile body 1, and the other mounting assembly is installed on one end face of the second pile body 2. One end of the connecting member 5 is snap-fitted into the mounting assembly on the first pile body 1, and the other end of the connecting member 5 is snap-fitted into the mounting assembly on the second pile body 2 to enable self-locking connection between the first pile body 1 and the second pile body 2.

[0041] Specifically, one end of the connecting member 5 is snap-fitted into the mounting assembly on the first pile body 1, and the other end of the connecting member 5 is snap-fitted into the mounting assembly on the second pile body 2, thereby enabling self-locking connection between the first pile body 1 and the second pile body 2. After the connecting member 5 is snap-fitted into the mounting assembly on the first pile body 1, the end of the second pile body 2 provided with the mounting assembly faces the end of the first pile body 1 having the mounting assembly. Through the self-weight action of the second pile body 2, the connecting member 5 is snap-fitted with the mounting assembly on the second pile body 2, thereby realizing the self-locking connection between the first pile body 1 and the second pile body 2.

[0042] It should be noted that the mounting assembly can be welded to the first pile body 1, the mounting assembly can also be fixedly connected to the first pile body 1 by bolts or screws, and the mounting assembly can also be fixedly connected to the first pile body 1 by any other means that can achieve the above functions, which will not be repeated here. Among them, the connection form between the mounting assembly and the second pile body 2 is similar to the connection form between the mounting assembly and the first pile body 1, which will not be repeated here.

[0043] That is to say, by providing the installation assembly and the connector 5, the first pile body 1 and the second pile body 2 can be self-lockingly connected, which reduces the difficulty of connecting the first pile body 1 and the second pile body 2, thereby improving the construction efficiency and having universal applicability. At the same time, the connection strength between the first pile body 1 and the second pile body 2 is improved, and the stability of the structure between the pile bodies is ensured. Compared with the prior art, the technical solution of the present invention avoids complex operations such as welding and bolt connection, reduces construction time and labor costs, and improves the reliability and durability of the connection.

[0044] In some embodiments of the present invention, Figure 1 As shown, the installation assembly includes a flange 3 and a clamping member 4, one flange 3 is on one end surface of the first pile body 1, and the other flange 3 is on one end surface of the second pile body 2, and the flange 3 is provided with the installation groove 31 (as shown in FIG. Figure 7 As shown), the clamping member 4 is installed in the installation groove 31.

[0045] Specifically, the two flanges 3 are respectively installed on one end surface of the first pile body 1 and the second pile body 2, providing a stable installation foundation for the self-locking connection of the first pile body 1 and the second pile body 2. The setting of the installation groove 31 enables the clamping member 4 to be installed with precision, ensuring the accuracy and stability of the connection. The matching installation of the clamping member 4 and the flange 3 simplifies the installation process and improves the installation efficiency. The installation groove 31 should be set to further ensure the accuracy and stability of the connection, solving the technical problems of the complex structure of the installation assembly and the inconvenience of installation.

[0046] Therefore, the technical solution of the present invention provides a stable installation foundation through the arrangement of the flange 3 and the clamping member 4, and ensures the accuracy and stability of the connection through the corresponding arrangement of the mounting groove 31 and the clamping member 4. The coordinated installation of the clamping member 4 and the mounting groove 31 simplifies the installation process, improves the installation efficiency, and solves the technical problems of the complex structure and inconvenient installation of the mounting assembly. Compared with the prior art, the technical solution of the present invention has higher installation efficiency and better connection stability.

[0047] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the mounting groove 31 is configured as an annular structure, and the clamping member 4 is configured as an annular spring sheet.

[0048] Specifically, the installation groove 31 can be set as a circular ring structure, and the installation groove 31 is arranged along the first direction (such as Figure 1 The cross-section in the Z direction is a "convex" structure, that is, the mounting groove 31 of the "convex" structure allows the annular spring sheet to be limited in the first direction after being installed in the groove from the opening of the mounting groove 31, wherein the design of the annular spring sheet makes the clamping member 4 elastic, thereby guiding the process of connecting the connecting member 5 to the first mounting component, and can automatically adjust the position during the installation process to ensure the close fit between the clamping member 4 and the mounting groove 31.

[0049] That is to say, the design of the mounting groove 31 of the annular structure and the clamping member 4 of the annular spring sheet effectively solves the problem of stable matching between the annular mounting groove 31 and the clamping member 4 of the self-locking connection mechanism of the pipe pile, ensuring that the connecting member 5 can be firmly clamped and realize the self-locking function. Compared with the prior art, this solution has higher connection stability and durability, simplifies the installation process, and improves construction efficiency.

[0050] In some embodiments of the present invention, Figure 2 , Figure 3 As shown, the two flanges of the clamping member 4 include a plurality of elastic portions 41 , and the elastic portions 41 are evenly distributed on the clamping member 4 .

[0051] The elastic part 41 refers to the part of the clip 4 that has elastic deformation capability. Through the uniform distribution design, the uniform distribution of elastic force of the clip 4 during installation can be ensured. Specifically, the elastic part 41 can be realized by providing a plurality of protrusions or depressions on the two flanges of the clip 4. These protrusions or depressions are evenly arranged on the clip 4, so that the elastic force is evenly distributed in various parts of the clip 4. As a preferred embodiment, the elastic part 41 can be realized by providing a plurality of separate tooth structures on the two flanges of the clip 4. These tooth structures are evenly distributed on the clip 4, so that the elastic force is evenly distributed in various parts of the clip 4 to achieve elastic deformation of the clip 4.

[0052] That is to say, the clamping member 4 can evenly distribute the elastic force during the installation process, thereby ensuring the stability and reliability of the installation. The evenly distributed elastic portion 41 can effectively solve the problem of uneven elastic distribution of the clamping member 4 during the installation process, and improve the overall performance and service life of the connector 5. Compared with the prior art, the technical solution of the present invention can significantly improve the uniformity of the elastic distribution of the clamping member 4 through the design of the evenly distributed elastic portion 41, thereby improving the installation effect of the connector 5.

[0053] It should be noted that the two flanges of the clamping member 4 are respectively located at the outer circumference of the clamping member 4 and the inner circumference of the clamping member 4 .

[0054] In some embodiments of the present invention, a plurality of limiting portions (not shown) are provided on the two flanges of the clamping member 4 , and the plurality of limiting portions are evenly distributed circumferentially on the clamping member 4 and install the clamping member 4 in the installation groove 31 .

[0055] Specifically, the design of the limiting portion can be realized in a variety of ways. For example, the limiting member can be set as a clip structure, and the limiting portion can be a protruding structure integrally formed with the clip 4, or can be an independent component that is separately manufactured and fixed to the clip 4 by welding or riveting. The cross-sectional shape of the limiting portion can be rectangular, trapezoidal or other shapes suitable for clipping, so as to ensure that it can closely match the inner wall of the mounting groove 31 to achieve the limitation of the first clip 4 and the second clip 4. In addition, the number and distribution density of the limiting portions can be adjusted according to actual needs to optimize the connection strength and stability.

[0056] That is to say, the limiting part can effectively and firmly install the clamping part 4 in the installation groove 31. This structure not only enhances the connection strength between the clamping part 4 and the installation groove 31, but also improves the stability and reliability of the entire self-locking connection mechanism. Compared with the prior art, the present invention solves the problem that the clamping part 4 is not firmly fixed in the installation groove 31 through the uniform distribution and tight fit of the limiting parts, thereby improving the self-locking effect and service life of the pipe pile connection.

[0057] In some embodiments of the present invention, Figure 5 , Figure 6 The connecting member 5 includes a first protrusion 51 and a second protrusion 52 . The first protrusion 51 is provided at one end of the connecting member 5 and is clamped in the clamping member 4 on the first pile body 1 . The second protrusion 52 is provided at the other end of the connecting member 5 and is clamped in the clamping member 4 on the second pile body 2 .

[0058] Specifically, the design of the first protrusion 51 and the second protrusion 52 enables the connector 5 to be firmly clamped in the clamping member 4, preventing the connector 5 from loosening or falling off during use, thereby ensuring the stability and reliability of the connection. The first protrusion 51 and the second protrusion 52 can be designed to be conical, which helps to provide better guidance and positioning during the clamping process, so that the connector 5 can be inserted into the clamping member 4 more smoothly. In addition, the conical design of the first protrusion 51 and the second protrusion 52 can also provide a larger contact area after clamping, thereby enhancing the strength and stability of the connection.

[0059] Therefore, the technical solution of the present invention realizes the self-locking connection between the first pile body 1 and the second pile body 2 by providing the first convex part 51 and the second convex part 52 to engage with the clamping part 4 on the first pile body 1 and the clamping part 4 on the second pile body 2, respectively. This design not only simplifies the connection process and improves the construction efficiency, but also ensures the stability and reliability of the connection, and solves the problems of the troublesome alignment of the pipe pile connection, high docking accuracy requirements, and insufficient connection strength in the prior art.

[0060] In some embodiments of the present invention, Figure 5 , Figure 6 As shown, the cross-sections of the first convex portion 51 and the second convex portion 52 along the first direction are tapered.

[0061] Specifically, the conical design not only simplifies the alignment process, but also enhances the stability of the connector 5, ensuring that the self-locking connection between the first pile body 1 and the second pile body 2 is more secure and reliable. Through this design, the connector 5 can automatically adjust its position during installation, reducing alignment errors and improving installation efficiency and connection strength.

[0062] As a preferred embodiment, the tapered angles of the first protrusion 51 and the second protrusion 52 can be adjusted according to actual application requirements to optimize the alignment and clamping effects. For example, the tapered angle can be set between 30 degrees and 60 degrees to ensure that sufficient guiding effect can be provided during the installation process, while avoiding the stability of the connection being affected by an angle that is too large or too small. In addition, the tapered design can also be combined with other auxiliary structures, such as guide grooves or guide protrusions, to further improve the alignment accuracy and installation efficiency.

[0063] Therefore, the technical solution of the present invention effectively solves the technical problems of difficult alignment and unstable connection of the connector 5 during installation through the conical design. Compared with the prior art, this design not only simplifies the installation process, but also significantly improves the reliability and stability of the connection, and is suitable for various engineering application scenarios requiring high-precision and high-strength connections.

[0064] In some embodiments of the present invention, Figure 7 As shown, the mounting groove 31 provided on the first pile body 1 is configured to correspond to the shape of the first convex portion 51 , and the mounting groove 31 provided on the second pile body 2 is configured to correspond to the shape of the second convex portion 52 .

[0065] This shape-corresponding design ensures the precise alignment and stable clamping of the connector 5 during installation. Specifically, the clamping member 4 limits the connector 5 in the first direction, and the shape-corresponding arrangement of the mounting groove 31 and the first protrusion 51 realizes the limiting of the connector 5 in the second direction, thereby realizing the fixed connection between the connector 5 and the mounting assembly, avoiding the problem of loose connection or failure due to shape mismatch. Similarly, the shape-corresponding arrangement of the mounting groove 31 and the second protrusion 52 also ensures the stable clamping of the connector 5 in the mounting assembly.

[0066] As a preferred embodiment, the shapes of the mounting groove 31 and the first protrusion 51 can be designed to be conical, so that the connector 5 can automatically align and achieve self-locking when inserted. Furthermore, the shapes of the mounting groove 31 and the second protrusion 52 can also adopt a similar conical design to ensure the stable clamping of the connector 5 in the mounting assembly. In addition, the depth and width of the mounting groove 31 can be adjusted according to the size of the connector 5 to ensure that the connector 5 can be fully inserted and fixed in the mounting groove 31.

[0067] Through this shape-matching design, the connector 5 can effectively self-lock the first pile body 1 and the second pile body 2, thereby improving the stability and reliability of the connection. Compared with the prior art, this design not only simplifies the installation process of the connector 5, but also improves the accuracy and stability of the connection, thereby avoiding the problem of loose connection or failure due to shape mismatch. Therefore, the technical solution of the present invention has significant advantages in practical applications.

[0068] In some embodiments of the present invention, Figure 6 As shown, the connecting member 5 also includes a connecting portion 53, which is arranged between the first convex portion 51 and the second convex portion 52, and a first clamping surface 54 is formed between the first convex portion 51 and the connecting portion 53, and the first clamping surface 54 abuts against the clamping member 4 on the first pile body 1 and connects the connecting member 5 to the first pile body 1; a second clamping surface 55 is formed between the second convex portion 52 and the connecting portion 53, and the second clamping surface 55 abuts against the clamping member 4 on the second pile body 2 and connects the connecting member 5 to the second pile body 2.

[0069] The design of the connecting portion 53 forms the first clamping surface 54 and the second clamping surface 55 between the first protrusion 51 and the second protrusion 52. The first clamping surface 54 cooperates with the clamping member 4 on the first pile body 1, and the second clamping surface 55 cooperates with the clamping member 4 on the second pile body 2, ensuring the stable clamping of the connecting member 5 in the installation assembly. The design of the connecting portion 53 enables the connecting member 5 to be evenly stressed during the self-locking connection process, avoiding loosening or failure of the connection due to uneven stress. Through the stop effect of the first clamping surface 54 and the second clamping surface 55, the connection between the connecting member 5 and the installation assembly is more secure, improving the self-locking effect and overall stability of the pipe pile connection.

[0070] Specifically, the connecting portion 53 can be implemented in various forms. For example, the connecting portion 53 can be designed to be cylindrical, rectangular or other geometric shapes to meet different installation requirements. The material of the connecting portion 53 can be selected from high-strength metal or composite materials to ensure its stability and durability when subjected to force. In addition, the connection between the connecting portion 53 and the first convex portion 51 and the second convex portion 52 can be welded, bolted or other mechanically connected to enhance the stability of the overall structure.

[0071] The present invention provides the connecting portion 53, such as Figure 6 As shown, the first clamping surface 54 and the second clamping surface 55 are formed between the first protrusion 51 and the second protrusion 52. The first clamping surface 54 cooperates with the clamping member 4 on the first pile body 1, and the second clamping surface 55 cooperates with the clamping member 4 on the second pile body 2, ensuring the stable clamping of the connector 5 in the installation assembly. The design of the connecting portion 53 enables the connector 5 to be evenly stressed during the self-locking connection process, avoiding loosening or failure of the connection due to uneven stress. Through the stop effect of the first clamping surface 54 and the second clamping surface 55, the connection between the connector 5 and the installation assembly is more secure, improving the self-locking effect and overall stability of the pipe pile connection. Compared with the prior art, the technical solution of the present invention has significant advantages in ensuring the stable clamping between the connector 5 and the installation assembly, can effectively avoid the problem of loosening or failure of the connection, and improves the self-locking effect and overall stability of the pipe pile connection.

[0072] It should be noted that the connecting member 5 can be set as an annular structural member corresponding to the first mounting groove 31, the connecting member 5 can also be set as a plurality of arc-shaped structural members and the curvature of the connecting member 5 corresponds to the first mounting groove 31, and the connecting member 5 can also be set as other structural members that can realize the above functions, which will not be described one by one here.

[0073] In some embodiments of the present invention, the mounting assembly and the connecting member 5 are rigid metal members.

[0074] Rigid metal parts are usually made of high-strength steel or alloy materials, which have excellent mechanical properties and can withstand large tension and pressure. Specifically, the materials of rigid metal parts can be selected from carbon steel, stainless steel, titanium alloy, etc. These materials not only have high strength and good durability, but also can maintain stable performance under harsh environmental conditions. As a preferred embodiment, the rigid metal parts can be manufactured by forging, casting or machining to ensure the uniformity and consistency of their structure.

[0075] By using rigid metal parts, the connector 5 can withstand greater stress at the pipe pile connection, ensuring the stability of the connection and the reliability of long-term use. Specifically, the high strength characteristics of the rigid metal parts enable it to effectively resist external loads and vibrations, thereby reducing fatigue damage at the connection. In addition, the durability of the rigid metal parts enables it to be used for a long time in a humid and corrosive environment without being easily damaged, further improving the service life of the connector 5 of the pipe pile.

[0076] Compared with the prior art, the technical solution of the present invention significantly improves the overall performance of the connecting member 5 of the pipe pile by using a rigid metal part as the connecting member 5. The high strength and durability of the rigid metal part enable it to maintain an excellent connection effect in a harsh engineering environment, solving the problems of insufficient connection strength and poor durability in the traditional connection method. Therefore, the technical solution of the present invention not only improves the reliability of the connecting member 5 of the pipe pile, but also simplifies the construction process and reduces maintenance costs.

[0077] In summary, the self-locking connection mechanism of the pipe pile of the present invention can be conveniently, quickly and simply operated, which improves the construction efficiency. The self-locking connection mechanism of the pipe pile only needs to be simply installed, and does not require careful manual alignment, and does not require alignment in the axial direction. The conical structure of the connector 5 has a guiding and alignment function, which solves the difficulty of centering and positioning when the pipe piles are docked in the prior art. At the same time, the connector 5 has strong bending, shear and tensile strength, and is suitable for various large-diameter pipe piles and foundation projects with high requirements for construction bearing capacity. The self-locking connection mechanism of the pipe pile of the present invention can solve the problems of troublesome alignment and difficult docking of mechanical pipe pile connections in the prior art. At the same time, the present invention does not need to be welded, which solves many problems and pain points of pipe pile welding in the prior art. The present invention has the advantages of simple operation, high connection strength, improved construction efficiency, and good connection effect.

[0078] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
