a concrete pile

Abstract

The invention relates to the field of concrete pipe piles, in particular to a concrete pipe pile. The concrete pipe pile comprises a reinforcing structure, a support structure, a traction structure, amounting rod, a sealing structure and a rubber ring; through arrangement of a reinforcing bar in the support structure, the firmness of a pipe pile main body is greatly improved; a first guide wheelis driven to rotate by a steel wire rope, so that tension on the first guide wheel is uniformly acted on the reinforcing bar, and the pipe pile main body is stressed more uniformly; when the pipe pilemain body is damaged, the first guide wheel is uniformly stressed through the steel wire rope; the acting force of the pipe pile main body is transferred to the reinforcing bar by the first guide wheel to effectively prevent immediate rupture of the pipe pile main body during colliding of the pipe pile main body, so that the tensile capacity of the pipe pile main body is greatly improved; the first guide wheel is rotationally connected with the reinforcing bar through a rotating shaft; and the first guide wheel is of a cylinder structure with a gradually reduced diameter from two ends to middle, so that the steel wire rope is conveniently limited, and the fixing effect of the pipe pile main body by the steel wire rope is better.

Description

technical field [0001] The invention relates to the field of concrete pipe piles, in particular to a concrete pipe pile. Background technique [0002] Pipe piles are divided into prestressed concrete pipe piles and prestressed high-strength concrete pipe piles according to the concrete strength grade or effective precompression stress. Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. Pretensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. Pipe piles are used in electricity as support rods for electric wires.

Problems solved by technology

[0003] However, when the concrete pipe piles used in mountainous areas are used to erect electric wires, the tensile performance of the pipe piles is very important. When the concrete pipe piles are installed in soft geological areas, it is necessary to install three stay ropes on the top of the pipe piles, so as to effectively Prevent the concrete pipe pile from collapsing under the pull of the cable and its own gravity. At the same time, when the tree breaks or the car hits the concrete pipe pile on the roadside, the pipe pile will break directly, and the internal steel bars of the pipe pile cannot support the pipe pile. serious accident
