Problems solved by technology
[0004] The interior of the current pre-tensioned prestressed concrete pipe piles is the main structure supported by steel strands and reinforced concrete bars, but the connection between the steel strands and the reinforced concrete bars is mainly through wire binding, while jacks are used to pull the piles. When the steel strand is stretched, it is easy to cause the wire to break off, which will make the reinforced concrete bar shift and affect the structural strength of the concrete pipe pile

The invention discloses a pretensioned prestressed concrete pipe pile. The left end and the right end of the concrete pipe pile body are provided with circular grooves, and the inner walls of the two circular grooves are fixedly connected with end plates, and the sides of the two end plates are provided with through holes. The inner wall of the through hole is provided with a steel strand, and the inside of the concrete pipe pile body is provided with a reinforced steel disc, and the inner wall of the reinforced steel disc is welded with a limit tube. The pre-tensioned prestressed concrete pipe pile is provided with end plates, concrete pouring layers, reinforced steel discs, rubber limit rings and limit pipes, so that the rubber limit rings can be used to limit the steel strands, so that the jack When the steel strand is stretched, the reinforcing steel disc will not be displaced, and the strength will be improved.
Description
technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to a pretensioning method prestressed concrete pipe pile. Background technique [0002] The pre-tensioning method is to tension the prestressed tendons before pouring the concrete, and temporarily anchor the tensioned prestressed tendons on the pedestal or the steel form, and then pour the concrete. When the prestressed tendons are sufficiently bonded to the concrete, the prestressed tendons are loosened, and the prestressed concrete is applied by means of the bonding between the concrete and the prestressed tendons. [0003] The pre-tensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by the pretensioned prestressing process and the centrifugal forming method. It is mainly composed of a cylindrical pile body, an end plate and a steel ferrule. . [0004] At present, the interior of the pre-tensioned prestressed concrete ...
