Description

A steel socket prestressed concrete water pipe

【Technical field】

The utility model relates to a concrete water delivery pipe, in particular to a one-stage steel socket prestressed concrete water delivery pipe.

【Background technique】

As is known, all kinds of concrete water pipes currently used in China mainly include self-stressed concrete pipes, prestressed concrete pipes and other concrete water pipes with various excuses; the manufacturing method of the first-stage prestressed concrete water pipes It is made by putting the inner mold and the outer mold together, injecting pressure water into the rubber sleeve of the inner mold and extruding, implementing hoop steel wire tensioning, and at the same time vibrating to make the concrete dense, and then curing, pressure relief, and demoulding processes. ; Although these pipes can achieve the purpose of water delivery to a certain extent, the repair rate of prestressed concrete pipes is very high after forming, and the cost of repair and maintenance is also relatively high. Due to their heavy weight, it directly affects the installation speed of on-site construction. And the permeability resistance is poor, and the service life is relatively short, and the interface of the conventional one-stage prestressed concrete water pipe adopts a single "O" rubber seal ring. Due to the high deformation rate of the rubber, the pressure test cannot be done at the joint of the pipe. Only after the installation is at a certain distance can the sealing of the joint be tested. Once there is penetration or leakage at the joint, it will delay the work of the staff. Construction time is reduced, and labor efficiency is also reduced.

【Content of invention】

In order to overcome the deficiencies in the background technology, the utility model provides a steel socket prestressed concrete water pipe. The utility model utilizes the steel socket provided at the mouth of the prestressed concrete water pipe and the outer edge of the steel socket The double sealing ring placed in the sealing groove realizes the change from the long-distance pressure test after installation to the root-to-root pressure test at the pipe interface after installation, and enhances the sealing and anti-seismic ability of the interface, making the construction easier. fast.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A steel spigot prestressed concrete water pipe, comprising a pipe body, a steel spigot and a socket, a socket is provided at the expanded diameter insertion end of the pipe body, and a steel socket is provided at the insertion end of the pipe body, wherein A socket steel ring is provided on the outer edge of the socket; one end of the steel socket is set in the pipe body, and the outer edge of the other end is provided with a boss and a sealing groove, and the inside of the pipe body is provided with a water channel , a diameter-expanding section is provided at the end of the water channel at the expansion-diameter insertion end of the pipe body; the inner wall of the expansion-diameter section matches the outer edge of the steel socket.

The steel socket prestressed concrete water pipe is provided with an external flare on the outside of the diameter expansion section.

The steel socket prestressed concrete water pipe has a gradual transition from small to large in diameter between the pipe body and the expanded diameter insertion end.

In the steel socket prestressed concrete water pipe, there are at least two sealing grooves on the steel socket.

By adopting the above-mentioned technical scheme, the utility model has the advantages as follows:

The steel socket prestressed concrete water pipe described in the utility model utilizes the steel socket provided at the plug-in end of the prestressed concrete water pipe, and the double sealing ring placed in the sealing groove on the outer edge of the steel socket strengthens the interface. The tightness and anti-seismic ability at the place realize the change from the long-distance pressure test after installation to the pressure test of the pipe joints at that time after installation. The utility model has the advantages of good sealing, quick construction and convenient maintenance.

【Detailed ways】

The utility model can be explained in more detail by the following examples, and the utility model is not limited to the following examples;

The steel socket prestressed concrete water pipe described in conjunction with accompanying drawing 1 includes a pipe body 1, a steel socket 4 and a socket 9, and a socket 9 is provided at the expanded diameter insertion end of the pipe body 1. The mating end of the socket is provided with a steel socket 4, wherein the outer edge of the socket 9 is provided with a socket steel ring 8; one end of the steel socket 4 is arranged in the pipe body 1, and the outer edge of the other end is provided There are bosses 2 and sealing grooves 3, and there are at least two sealing grooves 3 on the steel socket 4; the inside of the pipe body 1 is provided with a water channel 5, and the diameter-expanding insert of the pipe body 1 The end of the inner water channel 5 at the connecting end is provided with an expanding section 6, and the diameter between the pipe body 1 and the expanding diameter insertion end is a gradual transition from small to large; the inner wall of the expanding diameter section 6 and the steel socket The outer edge of 4 matches, and an outer flare 7 is provided on the outside of the diameter-expanding section 6 .

Implementation of the steel socket prestressed concrete water pipe described in the utility model, when in use, after the sealing ring is placed in the sealing groove 3 on the outer edge surface of the steel socket prestressed concrete water pipe 4 of the steel socket, the water pipe is made of steel The outer edge of the socket 4 is matched with the inner wall of the expanded diameter section 6 of another steel socket prestressed concrete water pipe to form a flexible joint with good sealing performance. Due to the double sealing rings placed in the sealing groove 3 Therefore, the sealing and anti-seismic ability of the interface are enhanced, so that the original long-distance test after installation can be changed to the pipe interface after installation. The root can be tested at that time, and the pipe joint has good sealing performance, strong anti-seismic ability, and convenient construction. Fast, good anti-corrosion performance, easy maintenance and other advantages.
