Description

Technical Field

[0001] This invention relates to the field of PHC pipe pile technology, and in particular to a corrosion-resistant reinforced PHC pipe pile. Background Technology

[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are hollow precast piles made with prestressed steel bars as the skeleton and high-strength concrete as the base material, formed by centrifugal molding and steam curing. PHC pipe piles need to be designed with corrosion resistance and reinforcement. PHC pipe piles are often used in corrosive environments such as coastal areas, saline-alkali land, and chemical industrial parks. Chloride ions, sulfates, and acidic substances in the soil can penetrate into the pipe pile and react chemically with the concrete, leading to steel bar corrosion, concrete carbonization, and reduced strength. This severely shortens the service life of the pipe pile and increases project maintenance costs and safety risks. Therefore, corrosion resistance and reinforcement are key upgrade designs for expanding the applicable environment of PHC pipe piles, extending the service life of projects, and ensuring the safety of foundation engineering.

[0003] Common PHC pipe piles mainly adopt the implementation method of ordinary anti-corrosion design. Ordinary anti-corrosion PHC pipe piles rely solely on the corrosion resistance of the concrete itself without additional anti-corrosion reinforcement measures. In highly corrosive environments, steel reinforcement corrosion and concrete deterioration are prone to occur, resulting in insufficient anti-corrosion effect and durability. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides a corrosion-resistant reinforced PHC pipe pile, which aims to improve the problem of insufficient durability of corrosion protection effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant reinforced PHC pipe pile, comprising a support plate, a rotating bracket fixedly disposed on the outer wall of the support plate, a flipping block fixedly disposed at the output end of the rotating bracket, a flipping bracket fixedly connected to the outer wall of the flipping block, a central shaft rotatably connected to the outer wall of the flipping bracket, a fixed seat rotatably connected to the outer wall of the central shaft, a gasket fixedly connected to the outer wall of the support plate, and a reinforcing pipe assembly fixedly disposed on the outer wall of the support plate.

[0006] Preferably, the reinforcing tube assembly includes an upper tube, the outer wall of which is fixedly disposed on the outer wall of the support plate, and a lower tube is attached to the outer wall of the upper tube.

[0007] Preferably, the outer wall of the flipping block is attached to the outer wall of the support plate, and the outer wall of the fixing seat is fixedly connected to the outer wall of the support plate.

[0008] Preferably, the outer wall of the gasket is attached to the outer wall of the flip bracket.

[0009] Preferably, a crank handle is rotatably connected to the outer wall of the upper tube, a drive shaft is fixedly connected to the outer wall of the crank handle, a rotating block is fixedly connected to the outer wall of the drive shaft, a spring is fixedly connected to the outer wall of the rotating block, a fixing block is fixedly connected to the outer wall of the spring, and a limit block is fixedly connected to the outer wall of the drive shaft.

[0010] Preferably, the outer wall of the drive shaft is rotatably connected to the inner wall of the upper tube, and the outer wall of the drive shaft is rotatably connected to the inner wall of the lower tube.

[0011] Preferably, the outer wall of the rotating block is slidably connected to the inner wall of the upper tube, and the outer wall of the spring is slidably connected to the outer wall of the drive shaft.

[0012] Preferably, the outer wall of the fixing block is fixedly connected to the outer wall of the upper tube, and the outer wall of the limiting block is attached to the inner wall of the lower tube.

[0013] The present invention has the following beneficial effects: 1. In this invention, the rotating support drives the flipping block, the flipping support and the central shaft to rotate, and in conjunction with the casting of the reinforced pipe assembly, the corrosion-resistant reinforced PHC pipe pile is stably flipped and cast, thereby improving the casting accuracy and structural reliability.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides: a corrosion-resistant reinforced PHC pipe pile, including a support plate 1, a rotating bracket 2 fixedly disposed on the outer wall of the support plate 1, a flipping block 3 fixedly disposed at the output end of the rotating bracket 2, a flipping bracket 4 fixedly connected to the outer wall of the flipping block 3, a central shaft 5 rotatably connected to the outer wall of the flipping bracket 4, a fixed seat 6 rotatably connected to the outer wall of the central shaft 5, a gasket 7 fixedly connected to the outer wall of the support plate 1, and a reinforced pipe assembly fixedly disposed on the outer wall of the support plate 1; Specifically, by activating the rotating bracket 2 fixed on the support plate 1 and driving the flipping block 3 to rotate, the rotation of the flipping block 3 drives the flipping bracket 4 to rotate, and the rotation of the flipping bracket 4 drives the central shaft 5 to rotate. The support plate 1 supports the fixed seat 6, ensuring the stability of the fixed seat 6. At the same time, the fixed seat 6 restricts and guides the central shaft 5, ensuring that the central shaft 5 is always in a self-rotating state during rotation, avoiding deviation or detachment during rotation. This is then used in conjunction with the reinforcing pipe assembly for pouring. The gasket 7 protects the flipping bracket 4, ensuring the safety of the flipping bracket 4 during flipping and extending the service life of the flipping bracket 4. This not only achieves the stable flipping and pouring of the PHC pipe pile reinforcing pipe assembly, effectively improving the pouring accuracy and structural reliability of the corrosion-resistant reinforced PHC pipe pile, but also provides stable flipping and pouring and mechanical support for the corrosion-resistant reinforced PHC pipe pile.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The reinforcing tube assembly includes an upper tube 8, the outer wall of which is fixedly mounted on the outer wall of the support plate 1, and a lower tube 9 is attached to the outer wall of the upper tube 8. Specifically, the upper pipe 8 is fixed to the support plate 1 to ensure the stability of the position of the upper pipe 8, and then the lower pipe 9 and the upper pipe 8 are joined together to facilitate subsequent casting and molding.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the flipping block 3 is attached to the outer wall of the support plate 1, and the outer wall of the fixing seat 6 is fixedly connected to the outer wall of the support plate 1. Specifically, the support plate 1 provides fixed support for the fixed seat 6, ensuring that the fixed seat 6 will not shift during operation. At the same time, it ensures that the flipping block 3 can always rotate along the outer wall of the support plate 1 during operation, improving smoothness and avoiding jamming that could affect the pouring progress.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the gasket 7 is attached to the outer wall of the flip bracket 4; Specifically, the shim 7 cushions the flipping bracket 4 that comes into contact with the support plate 1 after flipping, preventing the flipping bracket 4 from directly and rigidly colliding with the support plate 1, and preventing the device components from being worn or deformed due to the collision.

[0022] Reference Figure 1 , Figure 2 and Figure 4 A crank handle 10 is rotatably connected to the outer wall of the upper tube 8. A drive shaft 11 is fixedly connected to the outer wall of the crank handle 10. A rotating block 12 is fixedly connected to the outer wall of the drive shaft 11. A spring 13 is fixedly connected to the outer wall of the rotating block 12. A fixing block 14 is fixedly connected to the outer wall of the spring 13. A limit block 15 is fixedly connected to the outer wall of the drive shaft 11. The outer wall of the drive shaft 11 is rotatably connected to the inner wall of the upper tube 8. The outer wall of the drive shaft 11 is rotatably connected to the inner wall of the lower tube 9. The outer wall of the rotating block 12 is slidably connected to the inner wall of the upper tube 8. The outer wall of the spring 13 is slidably connected to the outer wall of the drive shaft 11. The outer wall of the fixing block 14 is fixedly connected to the outer wall of the upper tube 8. The outer wall of the limit block 15 is attached to the inner wall of the lower tube 9. Specifically, the crank 10, fixedly mounted on the upper tube 8, is rotated, which in turn drives the transmission shaft 11 to rotate and move. The rotation of the transmission shaft 11 then drives the rotating block 12 to move. The upper tube 8 and lower tube 9 restrict and guide the transmission shaft 11, ensuring it remains in linear rotation and preventing it from shifting or falling off due to external interference. The movement of the rotating block 12 then drives the spring 13 to move. The fixed block 14 restricts the movement of the spring 13 and the rotating block 12 to a predetermined range, preventing excessive movement, shifting, or falling off. Finally, the rotation of the transmission shaft 11 drives the limiting block 15 to rotate and move, thus enabling rapid disassembly and maintenance. This not only achieves rapid and accurate disassembly and assembly of PHC pipe piles, effectively improving the maintenance efficiency and reliability of corrosion-resistant reinforced PHC pipe piles, but also provides stable and rapid disassembly and assembly and mechanical support for corrosion-resistant reinforced PHC pipe piles.

[0023] Working principle: When closed pouring is required, the rotating bracket 2 fixed on the support plate 1 is activated and the flipping block 3 is driven to rotate. The rotation of the flipping block 3 drives the flipping bracket 4 to rotate, and the rotation of the flipping bracket 4 drives the central shaft 5 to rotate. This, in conjunction with the reinforcing pipe assembly, allows for pouring. This not only achieves stable flipping and pouring of the PHC pipe pile reinforcing pipe assembly, effectively improving the pouring accuracy and structural reliability of the corrosion-resistant reinforced PHC pipe pile, but also provides stable flipping and pouring and mechanical support for the corrosion-resistant reinforced PHC pipe pile. When maintenance is required, the crank handle 10 is turned to rotate, which in turn drives the transmission shaft 11 to rotate and move. The rotation of the transmission shaft 11 then drives the rotating block 12 to move, which in turn drives the spring 13 to move. The rotation of the transmission shaft 11 then drives the limit block 15 to rotate and move, thereby achieving rapid disassembly for maintenance. This not only achieves rapid and accurate disassembly and assembly of PHC pipe piles, effectively improving the maintenance efficiency and disassembly and assembly reliability of corrosion-resistant reinforced PHC pipe piles, but also provides stable rapid disassembly and assembly and mechanical support for corrosion-resistant reinforced PHC pipe piles. In other words, when in use, this mechanism not only achieves the stable flipping of the PHC pipe pile reinforcement pipe assembly for pouring, effectively improving the pouring accuracy and structural reliability of the corrosion-resistant reinforced PHC pipe pile, but also achieves the rapid and accurate disassembly and assembly of the PHC pipe pile, effectively improving the maintenance efficiency and disassembly and assembly reliability of the corrosion-resistant reinforced PHC pipe pile.
