Socket-faucet prestress reinforcing steel bar pipe with water blocking ring

Abstract

The invention relates to a socket-faucet prestress reinforcing steel bar pipe with a water blocking ring, comprising a socket, a faucet, a reinforcing steel bar framework, a concrete pipe core, a prestress steel wire and a protective layer, wherein both ends of the concrete pipe core are provided with the socket and the faucet, the concrete pipe core is internally and coaxially embedded with the reinforcing steel bar framework, and the prestress steel wire is wound on the outer wall of the concrete pipe core; the prestress steel wire and the outer wall of the concrete pipe core are fixedly provided with the protective layer; a water blocking ring is fixedly arranged on the socket in the concrete pipe core; and a water blocking ring is also fixedly arranged on the faucet in the concrete pipe core. The socket-faucet prestress reinforcing steel bar pipe with a water blocking ring has simple integral structure, scientific and reasonable design, stronger anti-permeability, lower cost and convenient mounting, and can effectively resist the increase of internal water pressure.

Description

technical field [0001] The invention relates to a concrete pipe, in particular to a socket prestressed reinforced concrete pipe with a water blocking ring. Background technique [0002] At present, concrete pipes are often used in municipal, water conservancy, electric power, and urban water supply and drainage systems, and steel socket prestressed concrete pipes occupy a large market in the application of large-diameter concrete pipes, and their advantages are obvious, such as: 1. It has a good ability to resist external pressure load and internal water pressure; 2. The connection process of the steel socket is simple and convenient for construction; 3. It has a good ability to resist uneven settlement, etc. The advantages of the above-mentioned pipes are inseparable from their specific structures. This kind of pipe structure includes: sockets, sockets, steel skeletons, concrete pipe cores, prestressed steel wires and protective layers. The sockets and sockets are fixed on ...

The advantages of the above-mentioned pipes are inseparable from their specific structures. This kind of pipe structure includes: sockets, sockets, steel skeletons, concrete pipe cores, prestressed steel wires and protective layers. The sockets and sockets are fixed on both ends of the concrete pipe cores. The steel skeleton is coaxially embedded in the concrete pipe core, the prestressed steel wire is wound on the outer wall of the concrete pipe core, and the protective layer is fixed on the prestressed steel wire and the outer wall of the concrete pipe core. The pipe has certain advantages, but 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 strength of the concrete pipe core and the pitch of the winding steel wire are constant, If the internal water pressure increases by 0.1Mpa on the upper line of the standard range, the concrete pipe core will leak, and most of the leakage will occur at the joint between the concrete and the steel socket or steel socket. If the strength of the concrete is increased and the winding steel wire is increased The method of screw pitch solves the leakage problem at the pipe socket and the socket, then the production cost will increase significantly, and the profit margin of the enterprise will be reduced accordingly, which will affect the economic benefits of the enterprise
