Abstract
The invention provides a cable conduit, which is suitable for the technical field of cable conduit production. The cable conduit is provided with a conduit body, the outer wall and the inner wall of the cable conduit are all provided with an epoxy resin layer, a glass fibrous layer is arranged between the conduit body and the epoxy resin layer, and the epoxy resin layer of the inner wall is provided with a modified polythene layer, thus the cable conduit has the characteristics of light weight, favorable flexibility, high bending resistance intensity, corrosion resistance and no interference. Moreover, the cable conduit also has the characteristics that comprehensive performance of the cable conduit is greatly enhanced, the cable conduit is more convenient to use, and meanwhile, the service life is long.
Description
Technical field
The present invention relates to the cable duct production technical field, relate in particular to a kind of cable duct.
Background technology
Along with the develop rapidly of communication cable and power cable, cable is more extensive in the application of municipal communication and coal gas dredging, and its effect is also further obvious, important.
But, the situation that current frequent outlet cable duct damages, the quality of cable duct and the protection of cable do not reached requirement mainly is because cable tube weight is heavier, and flexible relatively poor due to.
Summary of the invention
The invention provides a kind of cable duct, be intended to solve cable duct that prior art provides because weight is heavier, tenderness is lighter, causes cable duct damaged easily, do not have the problem of the effect of protection cable.
The present invention is a kind of cable duct of realizing like this, comprise pipeline body, be respectively equipped with epoxy resin layer on the outer wall of described pipeline body He on the inwall, be arranged between epoxy resin layer on the described pipeline body outer wall and the described pipeline body and be provided with glass layer, also be provided with the modified poly ethylene layer that forms by hot-dip plastic on the epoxy resin layer on the described pipeline body outer wall, the described epoxy resin layer that is arranged on the pipeline body inwall is provided with the stiffener that some edges circumferentially are evenly arranged.
As a kind of improvement, described pipeline body is fibre-cement pipe.
In the present invention owing on the outer wall of pipeline body and inwall, all be provided with epoxy resin layer, between pipeline body and epoxy resin layer, be provided with glass layer, be provided with the modified poly ethylene layer at the inwall epoxy resin layer, thereby make that cable duct has possessed that quality is light, flexible, bend resistance intensity height, corrosion resistance, the characteristics exempting to disturb, its combination property has obtained improving greatly, more convenient to use, simultaneously, possess the characteristics of long service life.
Description of drawings
Fig. 1 is the structure cutaway view of cable duct provided by the invention;
Among the figure: the 1-pipeline body; The 2-epoxy resin layer; The 3-glass layer; 4-modified poly ethylene layer; The 5-stiffener.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the structure cross-sectional schematic of cable duct provided by the invention.
Cable duct is provided with pipeline body 1, be respectively equipped with epoxy resin layer 2 on the outer wall of this pipeline body 1 He on the inwall, be arranged between epoxy resin layer 2 on pipeline body 1 outer wall and the pipeline body 1 and be provided with glass layer 3, also be provided with the modified poly ethylene layer 4 that forms by hot-dip plastic on the epoxy resin layer 2 on this pipeline body outer wall, this epoxy resin layer 2 that is arranged on the pipeline body inwall is provided with the stiffener 5 that some edges circumferentially are evenly arranged.
Wherein, pipeline body 1 can be fibre-cement pipe, this fibre-cement pipe adopts the advanced technologies such as electric reaming, be basic material with high-quality vinylon fibre, incorporate string, the high-strength height raw materials such as vinylon that rub, choosing height cement rolls the newly-increased strong pipe of cement of fiber of height that forms as main material by copying to get.
In the present invention, be arranged on outer wall and the epoxy resin layer on the inwall 2 of pipeline body 1, cable duct is played effective anticorrosive property, promoted the useful life of cable duct.
In the present invention, also be provided with the modified poly ethylene layer 4 that forms by hot-dip plastic on the epoxy resin layer 2 on the pipeline body outer wall, because the characteristics such as modified poly ethylene layer 4 has high resistance to compression, do not absorb water, moistureproof, airtight, lightweight, corrosion-resistant, long service life and conductive coefficient are low also have this characteristic from making cable duct.
Be provided with some stiffeners that circumferentially are evenly arranged 5 in the tube wall of pipeline body 1, this stiffener 5 can improve the mechanical strength of cable duct, and its anti-pressure ability is improved; In the tube wall of pipeline body 1, also be provided with simultaneously some along its connecting hoop that axially is evenly arranged (among the figure for providing), this connecting hoop is annular, stiffener 5 is connected as one successively, so just be equivalent to connect all stiffeners as a whole, and this integral body is placed on serves as a support frame in the cable duct, make the mechanical strength of cable duct and anti-pressure ability obtain further improving.
This cable duct is long service life not only, and quality is light, flexible, anticorrosive property, high temperature resistant, has stronger bend resistance intensity, very convenient use.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. cable duct, it is characterized in that, comprise pipeline body, be respectively equipped with epoxy resin layer on the outer wall of described pipeline body He on the inwall, be arranged between epoxy resin layer on the described pipeline body outer wall and the described pipeline body and be provided with glass layer, also be provided with the modified poly ethylene layer that forms by hot-dip plastic on the epoxy resin layer on the described pipeline body outer wall, the described epoxy resin layer that is arranged on the pipeline body inwall is provided with the stiffener that some edges circumferentially are evenly arranged.
2. require 1 described cable duct according to profit, it is characterized in that, described pipeline body is fibre-cement pipe.
