[0002] Concrete pipe piles have many advantages such as high single pile bearing capacity, stable molding quality, and reasonable price, and have been widely used in foundation treatment projects. However, due to the constraints of production, transportation, and construction conditions, the length of a single pile is limited, and pile connection is often required during construction. Reliable connection is the key to ensure the effective transfer of the load on the pile body. The quality of pile connection directly affects the construction quality and bearing capacity of prestressed pipe piles. A large number of engineering practices have shown that the joint of the pipe pile is the weakest link in the entire pile foundation, so the control of the quality of the pile connection is of great significance.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] Based on the content mentioned above, at present, concrete pipe piles are mainly connected by welding. However, welding connection has disadvantages such as being greatly affected by climate, difficulty in ensuring welding quality, high labor intensity for workers, and low construction efficiency. In addition, pipe pile foundation accidents caused by poor joint welding quality are not uncommon in actual projects.

[0034] To solve the above problems, please refer to Figures 1 to 4 This embodiment provides a connection structure for concrete pipe piles, which is used to connect two pipe piles 100 into one. The connection structure for concrete pipe piles includes a first main reinforcement anchoring end plate 1, a second main reinforcement anchoring end plate 2, a connector 3, a receiving hole 4 and a fixing component 5.

[0035] The first main reinforcement anchoring end plate 1 and the second main reinforcement anchoring end plate 2 are respectively preset at the two ends of the pipe pile 100. It should be noted that the first main reinforcement anchoring end plate 1 and the second main reinforcement anchoring end plate 2 can be pre-connected with the two ends of the main reinforcement inside the pipe pile 100 in advance during the process of manufacturing the pipe pile 100, so as to realize the first main reinforcement anchoring end plate 1 and the second main reinforcement anchoring end plate 2 being cast at the two ends of the pipe pile 100, which helps to ensure the structural strength.

[0036] The plug-in connector 3 is detachably arranged on the first main reinforcement anchoring end plate 1, and the plug-in connector 3 includes a limiting portion 31. The receiving hole 4 is arranged on the second main reinforcement anchoring end plate 2, and the receiving hole 4 is arranged in a "I" shape. The plug-in connector 3 can be inserted into the receiving hole 4. In order to improve the convenience of the plug-in connector 3 being inserted into the receiving hole 4, the end of the plug-in connector 3 is arranged in a conical shape. Such an arrangement makes it easier for the plug-in connector 3 to be inserted into the receiving hole 4. A limiting groove 41 is provided on the inner wall of the receiving hole 4, and the limiting portion 31 can be rotated into the limiting groove 41. The fixing component 5 is configured to limit the limiting portion 31 in the limiting groove 41.

[0037] In addition, in this embodiment, the plug-in connector 3 can be screwed to the first main reinforcement anchoring end plate 1, and the plug-in connector 3 is located at the center of the first main reinforcement anchoring end plate 1. It can be understood that the way in which the plug-in connector 3 is screwed to the first main reinforcement anchoring end plate 1 is more convenient for assembling the plug-in connector 3, and the connection is reliable. Of course, in other embodiments, an assembly hole compatible with the plug-in connector 3 can also be set on the first main reinforcement anchoring end plate 1, and the plug-in connector 3 can be plugged into the assembly hole after the assembly hole is filled with adhesive, which will not be described in detail.

[0038] In actual application, the connector 3 on one pipe pile 100 is first plugged into the receiving hole 4 on the other pipe pile 100, so that the two pipe piles 100 can be docked. Then, any one of the pipe piles 100 is rotated so that the limiting portion 31 falls into the limiting groove 41 on the other pipe pile 100, so that the two pipe piles 100 can be fixed. Finally, the limiting portion 31 is restricted in the limiting groove 41 by the fixing component 5, and the connection of the two pipe piles 100 is completed.

[0039] It can be understood that the above-mentioned concrete pipe pile connection structure realizes the connection of two pipe piles 100 by mechanical connection, which can avoid the negative impact of the welding connection method on factors such as climate and welding quality, thereby improving the reliability of the connection between the two pipe piles 100, and can also reduce the labor intensity of workers and improve construction efficiency. It can also be understood that by limiting the limiting part 31 in the limiting groove 41 through the fixing component 5, it can avoid the situation where the limiting part 31 and the limiting groove 41 are disengaged due to the rotation of any pipe pile 100 during the construction process, thereby making the connection between the two pipe piles 100 more secure.

[0040] Preferably, the fixing assembly 5 includes a fixing hole 51 and a fixing member 53. The fixing hole 51 is provided on the first main reinforcement anchoring end plate 1, and the fixing hole 51 is opened in a direction perpendicular to the axial direction of the first main reinforcement anchoring end plate 1, and is connected to the limiting groove 41. The fixing member 53 can be embedded in the fixing hole 51 and partially extend into the limiting groove 41 to cover the notch of the limiting groove 41 for the limiting portion 31 to enter. In order to improve the convenience of inserting the fixing member 53 into the fixing hole 51, the end of the fixing member 53 is set in a conical shape. Such a setting can improve the convenience of inserting the fixing member 53 into the fixing hole 51. When the connector 3 is inserted into the receiving hole 4 and the limiting portion 31 is located in the limiting groove 41, the fixing member 53 is gradually inserted into the fixing hole 51, and the fixing member 53 is partially extended into the limiting groove 41 to block the slot of the limiting groove 41 for the limiting portion 31 to enter, thereby limiting the limiting portion 31 in the limiting groove 41. The operation is simple and the structure is reliable.

[0041] It should be noted that if the fixing member 53 interferes with the limiting portion 31 after extending into the limiting groove 41, the pipe pile 100 needs to be rotated further so that the limiting portion 31 falls into the specified position in the limiting groove 41, and then the fixing member 53 is inserted further, which will not be described in detail.

[0042] Furthermore, the fixing assembly 5 further includes a reinforcement hole 52, which is arranged on the inner wall of the receiving hole 4, and the reinforcement hole 52 is connected with the limiting groove 41 through the receiving hole 4, and the fixing member 53 can be partially embedded in the reinforcement hole 52. Such an arrangement can make it difficult for the fixing member 53 to fall out of the fixing hole 51, thereby helping to improve the reliability of the connection structure for concrete pipe piles.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
