The invention discloses a pre-tensioning method prestressed concrete pipe pile. The pre-tensioning method prestressed concrete pipe pile comprises a concrete pipe pile main body, wherein the concretepipe pile main body is of a hexagonal tubular structure which is transversely placed; the surface of the concrete pipe pile main body is fixedly connected with reinforcing concrete ribs; circular grooves are formed in the left end and the right end of the concrete pipe pile main body; end plates are fixedly connected to the inner walls of the two circular grooves; through holes are formed in the side surfaces of the two end plates; steel strands are arranged on the inner walls of the through holes; a reinforcing steel bar disc is arranged inside the concrete pipe pile main body; and a limitingpipe is welded to the inner wall of the reinforcing steel bar disc. According to the pre-tensioning method prestressed concrete pipe pile, the end plates, a concrete pouring layer, the reinforcing steel bar disc, a rubber limiting ring and the limiting pipe are arranged, so that the steel strands can be conveniently limited by the rubber limiting ring, then when a jack is used for stretching thesteel strands, the situation that the reinforcing steel bar disc is driven to deviate is avoided, and the strength is improved.
Description
technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to a pretensioned prestressed concrete pipe pile. Background technique [0002] The pre-tensioning method is to stretch the prestressed tendons before pouring concrete, and temporarily anchor the stretched prestressed tendons on the pedestal or steel form, and then pour the concrete until the concrete curing reaches no less than 75% of the design strength value of the concrete. When the prestressed tendons are guaranteed to have sufficient bonding with the concrete, the prestressed tendons are relaxed, and the prestressed concrete is applied to the concrete 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 pre-tensioned prestressed technology and centrifugal forming method. It is mainly composed of cylindrical pile body, end pl...
