[0018] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] like Figures 1-3As shown, a prestressed concrete pipe pile with end plate and pin-type reinforced mechanical connection joint includes an upper end plate 100 and a lower end plate 200. The upper end plate 100 is connected to a connecting pin 110. The lower end plate 200 has a through hole for the pin to pass through downwards. A connecting sleeve 210 is located below the through hole on the lower side of the lower end plate. The connecting pin 110 has an annular groove 111 in the middle. The connecting sleeve 210 has a pair of clamping latches 220 that engage with the annular groove when the connecting pin is inserted. Spring rings 230 are fitted on the two clamping latches to pull them together towards the middle. This connection joint is used to connect the upper end plate of the upper section of the pile and the lower end plate of the lower section of the pile. The two clamping latches 500, which are locking elements, adopt a split design. When the connecting pin 110 is inserted, the two clamping latches 220 are engaged in the annular positioning groove from both sides to achieve connection.

[0021] In this embodiment, the clamping latch is arc-shaped, and the outer side of the clamping latch has an arc-shaped groove for mounting the spring ring to prevent the spring ring from falling off. The spring ring provides a force to the two clamping latches 220 to pull them together in the middle, and the elasticity of the spring ring holds the two clamping latches together to lock the connecting pin.

[0022] In this embodiment, a guide slide cover 240 is provided between the two clamping latches to open them and to fall downwards after being pushed by the connecting pin. The guide slide cover 240 is groove-shaped with its opening facing upwards; before the connecting pin is inserted, the guide slide cover 240 opens the two clamping latches to prevent them from closing prematurely, thus leaving space between the two clamping latches for the connecting pin to be inserted; during the connection process, the guide slide cover 240 falls off after being pushed by the connecting pin.

[0023] In this embodiment, the upper end plate is provided with a threaded hole, and the upper part of the connecting pin is provided with an external thread and is threadedly connected to the threaded hole of the upper end plate.

[0024] In this embodiment, a pressure cap 250 is provided at the opening of the connecting sleeve. The pressure cap 250 is used to cover the clamping lock to prevent it from falling out. The pressure cap 250 can be threaded or tightly fitted to the connecting sleeve.

[0025] In this embodiment, the upper part of the inner side of the connecting sleeve is provided with a stepped hole, the pressure cap is upside down on the stepped hole, and the clamping lock is located between the pressure cap and the stepped hole.

[0026] In this embodiment, the lower end of the connecting pin is tapered, wider at the top and narrower at the bottom.

[0027] In this embodiment, the connecting sleeve is welded and fixed to the lower side of the lower end plate.

[0028] Construction process: (1) First, drill threaded holes at the set position on the upper end plate of the upper section pile, and then pour them together with the prestressed concrete pipe pile of the upper section pile; (2) Drill through holes at the set position on the lower end plate of the lower section pile, and then weld the assembled clamping lock, spring ring, guide slide cover, and pressure cover connecting sleeve below the through hole, and pour them together with the prestressed concrete pipe pile of the lower section pile; (3) When connecting on site, screw the connecting pin into the screw hole of the upper end plate, and then insert the connecting pin into the through hole of the lower end plate. Use the weight of the upper section pile to make its built-in support slide cover slide down, so that the clamping lock on both sides is inserted into the annular groove of the connecting pin under the tightening force of the spring ring, and the connection is achieved.

[0029] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0030] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0031] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0032] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
