Technical Field
The utility model relates to the technical field of pipelines, in particular to an underground heat supply pipeline.
Background
A pipe is a device for transporting a gas, liquid or fluid with solid particles connected by pipes, pipe couplings, valves, etc. Generally, a fluid is pressurized by a blower, a compressor, a pump, a boiler, etc., and then is transferred from a high pressure portion to a low pressure portion of a pipe, or is transferred by using the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and gas, agricultural irrigation, hydraulic engineering and various industrial devices, and in urban heat supply systems, heat supply pipelines are one of important components. However, the existing heat supply pipeline has the following problems: 1. the underground pipeline is easy to be damaged by the movement of the stratum, so that the heat-insulating layer inside the underground pipeline and even the pipeline body are damaged; 2. the pipe connection is relatively cumbersome, requires a large amount of constructors to operate, and is time-consuming and labor-consuming. In patent CN202020737272.0, a submarine pipeline protection shell made of regenerated carbon fiber composite is disclosed, which is in the shape of a semi-cylinder and sequentially comprises an outer anticorrosion layer, a middle buffer layer and an inner pressure resistant layer from outside to inside, wherein the outer anticorrosion layer, the middle buffer layer and the inner pressure resistant layer are all coaxially arranged; the middle buffer layer is internally provided with a reinforcing screen plate, and the reinforcing screen plate is coaxial with the middle buffer layer and is positioned in the middle buffer layer. The steel has the advantages of corrosion resistance, light weight, easy molding, recyclability and the like. But not against the pipeline pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides an underground heat supply pipeline. Through setting up the protective layer that includes, cushion filler, elastic protection layer and rigidity protective layer, for the pipeline provides better protection, avoid the pipeline to appear damaging because of natural disasters such as earthquake, through set up the connecting pipe between per two pipeline bodies, convenient and swiftly that can be more connect fixedly between per two sections pipelines, solved the underground heat supply pipeline and easily appear damaging and the inconvenient technical problem of construction because of the earthquake.
The purpose of the utility model is realized by the following technical scheme:
