Prestressed reinforced concrete pipe with waterproof ring of socket

Abstract

The invention relates to a prestressed reinforced concrete pipe with a waterproof ring of a socket, comprising a socket, a supporting port, a reinforced frame, a concrete pipe core, prestressed steel wires and protecting layers, wherein both ends of the concrete pipe core are provided with the supporting port and the socket; the reinforced frame is coaxially embedded into the concrete pipe core; the outer wall of the concrete pipe core is twisted with the prestressed steel wires; the prestressed steel wires and the outer wall of the concrete pipe core are fixedly provided with the protecting layers; and the socket in the concrete pipe core is fixedly provided with a waterproof ring. The invention has the advantages of simple integral structure, scientific and reasonable design, stronger impermeability, lower cost and convenient installation, and can effectively prevent internal pressure from increasing.

Description

technical field [0001] The invention relates to concrete pipes, in particular to a prestressed reinforced concrete pipe with a water blocking ring at the socket. Background technique [0002] The structure of the prestressed reinforced concrete pipe includes: socket, socket, steel skeleton, concrete pipe core, prestressed steel wire and protective layer, the socket and the socket are fixed at both ends of the concrete pipe core, and the steel skeleton is coaxially embedded in the concrete pipe core Inside, the prestressed steel wire is wound on the outer wall of the concrete tube core, and the protective layer is fixed on the prestressed steel wire and the outer wall of the concrete tube core. The advantages are obvious, for example: 1. It has better resistance to external pressure loads and internal 2. The connection process of the steel socket is simple and the construction is convenient; 3. It has a good ability to resist uneven settlement, etc. The advantages of the abov...

AI Technical Summary

Problems solved by technology

Although the concrete pipe with the above structure has certain advantages over other concrete pipes, in practical application, it is necessary to set the strength of the concrete pipe core and the pitch of the winding steel wire according to the working conditions to adapt to different internal water pressure values. When the concrete pipe core When the strength and the pitch of the winding steel wire are constant, the concrete pipe core will leak when the internal water pressure increases by 0.1Mpa above the standard range, and most of the leakage occurs at the joint between the concrete and the steel socket. If the concrete strength is increased And the method of increasing the pitch of the winding steel wire to solve the leakage problem at the pipe socket will greatly increase the production cost and reduce the profit margin of the enterprise accordingly, which will affect the economic benefits of the enterprise
