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

Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] The prestressed concrete pipe without longitudinal reinforcement in the steel socket is composed of a socket 1, a socket 5, a concrete pipe core 2, a prestressed steel wire 3, and a protective layer 4, and the protective layer is cement mortar. The socket and the socket are made of metal and coaxially fixed at both ends of the concrete pipe core respectively, the protective layer is coaxially made on the outer wall cylinder of the concrete pipe core, and the prestressed steel wire is wound on the outer wall column of the concrete pipe core in the protective layer face.

[0017] The socket of the present invention is a flexible interface, so it has good water-tightness, and can effectively ensure the airtightness of the overall pipelin...

Abstract

The invention relates to a steel bell-and-spigot steel longitudinal-bar-free 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 made on the outer wall surface of the pre-stressed concrete pipe core, and the pre-stressed steel wire is wound on the outer wall surface of the pre-stressed concrete pipe core. The steel pipe bell-and-spigot steel longitudinal-bar-free pre-stressed concrete pipe has simple overall structure, scientific and reasonable design, and good durability, barrier property and water resistance at joints; the steel consumption is less, the maintenance is convenient, the operation is simple, and the construction cost of the product is greatly reduced, 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 sockets and no longitudinal reinforcement. 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 fra...
