[0015] By designing specialized supports for shared piles, the feasibility of shared pile construction is ensured. The supports for installing each module are separated, increasing the adjustment space for offshore construction.

[0016] Precast pipe piles are driven into the ground, and then photovoltaic support modules are installed. The corner points of the photovoltaic support modules are installed so that the corner points are connected to the supports on the corresponding embedded parts that are closest to the photovoltaic support modules.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a pipe pile for the construction of offshore photovoltaic support modules, which solves the problem that each photovoltaic support module 1 has four pipe piles at its bottom for support, resulting in a large number of pipe piles used for installation. By welding the pre-embedded parts 21 onto the precast pipe piles 3 before driving the precast pipe piles 3, the application eliminates the need for welding the pre-embedded parts 21 at sea, improves construction efficiency, reduces construction costs, and reduces the risks of offshore construction.

[0025] By designing a special common pile support 4, the feasibility of common pile construction is ensured. The support 4 for each module installation is separated, increasing the adjustment space for offshore construction.

[0026] The precast pipe piles 3 are driven into the ground. At this time, the photovoltaic support module 1 is installed. The corner points of the photovoltaic support module 1 are installed so that the corner points are installed with the supports 4 on the corresponding embedded parts 21 that are closest to the photovoltaic support module 1. By installing the four corner points of the photovoltaic support module 1 with the supports 4 on the four embedded parts 21, the supports 4 on the embedded parts 21 are installed with the adjacent photovoltaic support modules 1, so as to achieve shared piles and greatly reduce the number of precast pipe piles 3 used.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a pipe pile for the construction of offshore photovoltaic support modules.

[0029] According to the appendix Figure 1-4 As shown, it includes a precast pipe pile 3, a precast pipe pile head sealing plate 5 is provided on the precast pipe pile 3, and a pipe pile component 2 is provided on the precast pipe pile head sealing plate 5. Several of the pipe pile components (2) are arranged in rows and columns to form a matrix grid, and the pipe pile components (2) are set at the corner points of the photovoltaic support module (1). The pipe pile components (2) are used to install the photovoltaic support module (1).

[0030] Four pipe piles 2 are used together to install one photovoltaic support module 1;

[0031] Pipe pile component 2 includes embedded component 21;

[0032] Before pile driving, the embedded part 21 is welded to the precast pipe pile 3, which eliminates the need for welding the embedded part 21 at sea, improves construction efficiency, reduces construction costs and reduces the risks of offshore construction.

[0033] The precast pipe pile head sealing plate 5, together with the embedded part 21, seals the opening of the precast pipe pile 3, effectively preventing soil, mud or groundwater from entering the interior of the precast pipe pile 3, and ensuring the cleanliness and dryness of the cavity inside the precast pipe pile 3.

[0034] Four supports 4 are provided above the embedded part 21.

[0035] Before driving the precast pipe piles 3, the embedded parts 21 are welded onto the precast pipe piles 3, and the four supports 4 are set separately. The precast pipe piles 3 are driven into the ground. At this time, the photovoltaic support module 1 is installed. The corner points of the photovoltaic support module 1 are installed so that the corner points are installed with the supports 4 on the embedded parts 21 that are closest to the photovoltaic support module 1. By installing the four corner points of the photovoltaic support module 1 with the supports 4 on the four embedded parts 21, the supports 4 on the embedded parts 21 are installed with the adjacent photovoltaic support modules 1, so as to achieve shared piles and greatly reduce the number of precast pipe piles 3 used.

[0036] By designing a special common pile support 4, the feasibility of common pile construction is ensured. The support 4 for each module installation is separated, increasing the adjustment space for offshore construction.

[0037] The back of the precast pipe pile head sealing plate 5 is provided with a socket-type cross connector 23, which is inserted into the precast pipe pile 3.

[0038] By setting the socket-type cross connector 23 as a cross-shaped stiffening rib, it can adapt to the impact of the heavy hammer and enhance rigidity.

[0039] Ventilation holes are provided on the precast pipe pile head sealing plate 5, and exhaust holes 24 are provided on the embedded part 21 corresponding to the precast pipe pile head sealing plate 5.

[0040] During the pile driving process, the high-pressure gas generated by the hammering is discharged through the vent holes.

[0041] A concrete steel bar 22 is fixedly connected to the back of the embedded part 21, and the concrete steel bar 22 is set with a corresponding support 4.

[0042] Concrete steel bars 22 are used to enhance the overall strength of the pipe pile.

[0043] A steel plate hoop 25 is provided on the back of the embedded part 21, and the steel plate hoop 25 is provided corresponding to the concrete steel bar 22.

[0044] The steel plate hoop 25 encloses the concrete steel bar 22 and the concrete in the precast pipe pile 3 to form radial restraint, so that the concrete is in a triaxial compression state, which significantly improves the compressive strength and ductility and reduces the risk of brittle failure.

[0045] A lifting head 41 is fixedly connected to the support 4.

[0046] The lifting head 41 is used in conjunction with the crane to lift the precast pipe pile 3. At the same time, when the lifting head 41 is subjected to the impact of the heavy hammer, the spherical design of the lifting head 41 allows the impact force to be transmitted more evenly to the precast pipe pile 3, avoiding local stress concentration and reducing the possibility of concrete cracking at the top of the pile.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
