Problems solved by technology
Its disadvantages are: the reinforcement ring and the main body of the pipe pile are integrally formed by concrete, and the structural strength of the reinforcement ring is lower than that of the pipe pile body with a built-in steel cage, which is easy to damage, especially when it is applied to hydraulic projects, such as high pile wharf, concrete pipe The upper part of the pile is exposed outside, and the reinforcing ring is easily damaged and peeled off after encountering external collisions

The invention relates to a prestressed concrete pipe pile with reinforcing rings. The prestressed concrete pipe pile mainly comprises a concrete pipe body and a steel reinforcement cage arranged in the concrete pipe body; and the surface of the concrete pipe body is provided with concrete reinforcing rings integrated with the concrete pipe body at intervals along the axial direction. The prestressed concrete pipe pile is characterized in that steel plates coat the surfaces of the concrete reinforcing rings. Because the steel plates coat the surfaces of the concrete reinforcing rings, the strength of the surfaces of the concrete reinforcing rings is greatly improved, and the concrete reinforcing rings are hardly damaged or hardly fall off when collided outside and are particularly suitable for places requiring exposed concrete pipe piles, such as long piled wharfs of water conservancy projects.
Description
Technical field [0001] The invention relates to a prestressed concrete pipe pile, in particular to a prestressed concrete pipe pile suitable for hydraulic projects. Background technique [0002] With the development of concrete technology, the technology of concrete pipe piles has matured. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. [0003] The bearing capacity of traditional concrete pipe piles is only affected by side friction resistance and pile tip friction resistance. To increase the bearing capacity, it can only be achieved by increasing the pipe diameter or length, which correspondingly increases the construction cost and difficulty. Later, a concrete pipe pile with a reinforcing ring on the surface appeared. The reinforcing ring was arranged on the surface of the main body of the pipe pile at an axial interval, and the friction between the reinforcing r...
