Pressure backfill type pipe connection piece

Abstract

A pressure backfill type pipe connection piece comprises a clamping piece and an elastic compression ring, wherein the clamping piece is in an opened annular shape, the section of the clamping piece is in a U shape, and the elastic compression ring is located on the inner edge of the clamping piece. The pressure backfill type pipe connection piece further comprises a clamping bolt, a left fixing rod and a right fixing rod, wherein the left fixing rod and the right fixing rod are transversely fixed to the two sides of an opening of the clamping piece respectively. Fixing rings are arranged on the two sides of the elastic compression ring respectively. A chrome-steel alloy pipe serves as the clamping piece, and the inner surface and the outer surface of the clamping piece, the outer surface of the left fixing rod, the outer surface of the clamping bolt and the outer surface of the right fixing rod are each coated with an anti-corrosion coating with the thickness of 0.1 mm to 0.5 mm. In this way, the pressure backfill type pipe connection piece is simple in structure, pressure backfill type pipe connection pieces can be conveniently matched, operation is convenient, pipes can be rapidly connected, the anti-corrosion effect is good, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pressure backfill type pipe connection piece. Background technique [0002] With the continuous improvement of people's living standards, there are more and more various infrastructure constructions, which require pipelines to realize the transportation of water, oil, gas, etc., but as people gradually pay attention to the environment, they also hope that such infrastructure constructions can possible reduction of environmental impact. [0003] In the existing technology, in order to realize the pipeline fixing and construction, the following two methods are commonly used: one is the underground buried pressure pipeline, which means that the pipeline is buried in the ground, and the steel pipe is surrounded by a layer of reinforced concrete and surrounding rock. Although the pipeline is fixed underground, the construction is complicated, the adaptability is poor, t...

[0003] In the existing technology, in order to realize the pipeline fixing and construction, the following two methods are commonly used: one is the underground buried pressure pipeline, which means that the pipeline is buried in the ground, and the steel pipe is surrounded by a layer of reinforced concrete and surrounding rock. Although the pipeline is fixed underground, the construction is complicated, the adaptability is poor, the cost is high, and the damage to the environment is great; the second is the open-air penstock, which means that the penstock is exposed on the surface and is fixed by the township and buttresses , although this method can reduce the damage to the environment, the open-air type is easy to damage and affects the vegetation and normal use of the ground, which also has major defects
