Description

Technical Field

[0001] The utility model relates to the technical field of MPP power pipes, in particular to an impact-resistant, heat-resistant and flame-retardant MPP power pipe with high corrosion resistance. Background Art

[0002] MPP power pipe is also called (MPP power cable protection pipe, MPP cable protection pipe), which is divided into excavation type and non-excavation type. MPP non-excavation power pipe is also called MPP jacking pipe or dragging pipe. MPP power pipe uses modified polypropylene as the main raw material. It does not require a lot of mud, excavation and damage to the road surface. It is a construction project for laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional "trench digging and pipe laying method", the non-excavation power pipe project is more in line with the current environmental protection requirements, eliminating the dust and traffic congestion caused by traditional construction. The factors that disturb the public, this technology can also be used to lay pipelines in some areas where excavation operations cannot be implemented, such as monument protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc.

[0003] However, since the existing power pipes do not have a reinforced pressure-bearing structure, the pipes may rupture and be damaged after being compressed; the existing power pipes do not have a heat-insulating and flame-retardant structure, and naturally do not have the ability to insulate and flame-retardant; since the power pipes need to be buried deep underground, without an anti-corrosion structure, the underground environment can easily cause damage to the pipes.

[0004] Therefore, it is very necessary to invent an impact-resistant, heat-resistant and flame-retardant MPP power pipe with high corrosion resistance. Utility Model Content

An impact-resistant, heat-resistant and flame-retardant MPP power pipe with high corrosion resistance includes a power pipe body, a thermal insulation layer, a flame retardant pad, a corrosion-resistant outer package and a cable, wherein: the thermal insulation layer is fixedly installed on the outside of the power pipe body, and the flame retardant pad is wrapped around the outside of the thermal insulation layer, and the corrosion-resistant outer package is fixedly installed on the outside of the flame retardant pad; the cable is located inside the power pipe body; the flame retardant pad includes a buffer layer and an adhesive layer, and the buffer layer is fixedly installed on the outside of the thermal insulation layer through the adhesive layer.

[0007] The supporting matrix inside the power pipe body adopts a pipe supported by modified polypropylene, and the reinforced skeleton adopts a spiral steel metal structure, and the inner protective shell adopts a plastic pipe; the reinforced outer armor adopts a stainless steel metal pipe with a thickness of 0.1mm, which has the following functions: ① Support and bearing function: the power pipe body provides the support and bearing capacity of the entire pipeline system, ensuring the stability and structural integrity of the pipeline during installation and use; ② Protecting internal cables: as the main part of the power pipeline, it can effectively protect the internal cables from damage by the external environment, such as mechanical impact, chemical corrosion, high temperature, etc.; ③ Pressure bearing: the reinforced skeleton can withstand the pressure in the vertical direction to prevent the external impact from causing the overall collapse of the power pipe body; ④ Protection: the reinforced outer armor can withstand stabbing or scratching from the outside, preventing sharp objects from the outside from easily entering the pipeline and preventing damage to the cables.

[0010] The corrosion-resistant outer package uses a plastic pipe. During installation, its inner diameter is first enlarged through low temperature. After the internal structure passes through the corrosion-resistant outer package, it is slowly heated up so that the corrosion-resistant outer package is tightly wrapped around the outside of the flame-retardant pad. It has the following functions: ① Anti-corrosion protection: The corrosion-resistant outer package can provide effective anti-corrosion protection for the power pipeline, prevent the corrosion of the pipeline material by chemicals and moisture in the external environment, and extend the service life of the power pipeline; ② Environmental adaptation: The material of the corrosion-resistant outer package usually has good environmental adaptability and can withstand various harsh environmental conditions, such as high humidity, acid and alkali environment, etc., to maintain the stability and integrity of the pipeline structure.
