Steel faucet longitudinal rib prestressed concrete pipe

Abstract

The invention relates to a steel bell-and-spigot longitudinal bar pre-stressed concrete pipe which is composed of a pipe socket, a faucet, a pre-stressed concrete pipe core, a pre-stressed steel wire and a protective layer. The pipe socket and the faucet are respectively fixed on the two ends of the pre-stressed concrete pipe core, the protective layer is coaxially disposed on the outer wall surface of the pre-stressed concrete pipe core, the pre-stressed steel wire is wound on the outer wall surface of the pre-stressed concrete pipe core, wherein a plurality of longitudinal bars which are axially embedded and have the same diameters are uniformly distributed in the pre-stressed concrete pipe core, and the two ends of each longitudinal bar are fixedly arranged on the pipe socket and the faucet. The steel pipe bell-and-spigot longitudinal bar pre-stressed concrete pipe has simple overall structure, scientific and reasonable design, good durability, barrier property and water resistance at joints, less steel consumption, convenient maintenance, simple operation and greatly reduced construction cost of the product, thereby creating the conditions for the wide application of the pre-stressed concrete pipes.

Description

technical field [0001] The invention relates to concrete pipes, in particular to a prestressed concrete pipe with steel socket longitudinal bars. Background technique [0002] Steel socket prestressed concrete pipe is a pipe mainly used in municipal, water conservancy, electric power, and urban water supply and drainage systems. It is also often used in industrial water pipelines, farmland irrigation, and factory pipe networks. The current cost of prestressed concrete pipes with steel sockets is relatively high, and the main reasons for the high cost of prestressed concrete pipes with steel sockets are: 1. The rise in steel prices causes the cost to increase. The concrete pipe core is embedded with a cylindrical steel skeleton, which is formed by binding or welding multiple longitudinal bars and circumferential steel bars, and the amount of steel used is relatively large; 2. The manufacturing cost of the steel skeleton is relatively high. When the steel frame is bound manua...

AI Technical Summary

Problems solved by technology

When the steel frame is bound manually, the production efficiency is low, the production cycle is long, and the defective rate is high; when the steel frame is fixed by welding with special equipment, although the production cycle is shortened and the defective rate is reduced, the mechanical equipment higher cost
