Reinforced concrete water pipe

Abstract

The invention provides a reinforced concrete water pipe, which includes a concrete pipe core and a steel skeleton. The concrete pipe core is generally cylindrical. The inner diameter of the mouth support ring is larger than the outer diameter of the socket support ring, and the inner wall of the concrete tube core is provided with an anti-corrosion coating; the steel skeleton is generally cylindrical and formed by connecting ring steel bars and axial main bars, and the steel skeleton is coaxially embedded in the In the concrete pipe core: the inner wall of the socket support ring and the outer wall of the socket support ring are respectively provided with a steel socket and a steel socket, and the steel socket and the steel socket are respectively welded to the two ends of the axial main reinforcement of the steel skeleton, and the steel socket A first annular groove is provided on the end face of the inner concrete pipe core. The invention effectively prevents sewage from directly contacting steel sockets, steel sockets and other metal parts and concrete tube cores, avoids pipeline leakage due to corrosion and penetration, and avoids environmental pollution.

Description

technical field [0001] The invention relates to the field of drainage pipes, in particular to a reinforced concrete water pipe. Background technique [0002] Drainage pipes are an indispensable facility in municipal, water conservancy, road and bridge, urban water supply and drainage, industrial water delivery, agricultural water delivery and other systems, generally including concrete, reinforced concrete or high-density polyethylene (HDPE) materials, of which reinforced concrete The compressive strength of water pipes is higher than other types, and it is suitable for fields that require larger pipe diameters. The interface types of existing reinforced concrete water pipes generally include tongue-and-groove type, flat type and socket type, and the specific application scenarios are also different according to their different structures. Since reinforced concrete water pipes are mostly used for sewage discharge, the sewage often contains a large number of microorganisms a...

AI Technical Summary

Problems solved by technology

Since reinforced concrete water pipes are mostly used for sewage discharge, the sewage often contains a large number of microorganisms and corrosive acid-base substances. However, the existing reinforced concrete water pipes have defects in sealing and corrosion resistance. When in use, sewage can still flow from the interface. The gap at the place penetrates out and touches the socket parts made of metal, or the sewage directly contacts the concrete component and infiltrates, so after long-term use, it will cause sewage leakage due to corrosion and infiltration, which will affect the service life of the product and even environmental pollution
