Prestressed concrete high-strength anti-corrosion pipe pile and production method thereof

Abstract

The invention provides a prestressed concrete high-strength anti-corrosion pipe pile. The anti-corrosion pipe pile comprises a pile body and end plates, the two end plates are symmetrically arranged at the two ends of the pile body, a reinforcement cage is arranged in the pile body, and each end plate comprises a connecting plate and a reinforcing pipe sleeve. The end plates which are designed ina split assembly mode are adopted, so that the production and machining process is simpler and more convenient. The reinforcing pipe sleeve welded in the groove can prevent the connecting plate from being deformed and damaged in the pile sinking process through the limiting and supporting effects of the reinforcing pipe sleeve on the connecting plate. In addition, the reinforcing pipe sleeve can increase the contact area between the connecting plate and the pile body, and therefore connection between the end plates and the pile body is firmer. The concrete with a water-cement ratio of 0.28-0.29 is concrete between dry hard concrete and plastic concrete, and due to the fact that the water-cement ratio is very low, the concrete is very low in permeability, excellent in corrosion resistance and high in strength.

Description

technical field [0001] The invention relates to the technical field of prestressed concrete high-strength pipe piles, in particular to a prestressed concrete high-strength anti-corrosion pipe pile and a production method thereof. Background technique [0002] Existing prestressed concrete piles have high single pile bearing capacity, low price, good bending resistance, small settlement, stable and reliable quality, fast construction speed, short construction period, civilized construction site, no sand, gravel, cement slurry pollution, etc. Features, has been widely used in industrial buildings, civil buildings and bridges, ports and other basic projects. [0003] Prestressed concrete pipe piles mainly include three parts: end plate, pile body and steel skeleton. Among them, due to the small contact area between the end plate and the pile body, the connection is not firm, and in the process of pile sinking, due to the lack of stable support , so the end plate is easily defo...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: the prestressed concrete pipe pile mainly comprises three parts of end plate, pile body and steel skeleton, wherein, because the contact area between end plate and pile body is little, Therefore, the connection is not firm, and during the pile sinking process, due to the lack of stable support, the end plate is easily deformed by compression. In addition, the existing prestressed concrete pipe pile has a high permeability, so it is easy to seep water and has poor anti-corrosion performance
