Description
Technical field
The utility model relates to a kind of protective casing, is specifically related to a kind of type ground-buried power cable protecting pipe.
Background technology
Plastic pipe is compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and fiber cable jacket, industrial fluids conveying, agricultural irrigation.Plastic conduit is an important branch in the numerous parts of chemical building material, from using the difference classification of chemical materials, plastic conduit can be divided into polyethylene (PE) pipe, polyvinyl chloride (PVC) pipe, polypropylene (PP) pipe, ABS pipe, polybutene (PB) pipe etc.
Along with the development of electric utility, cable obtains large-scale promotion in county town power grid construction and transformation.Laying of cable line has three kinds of methods conventionally: the one, and directly buried installation, the 2nd, cable tunnel lays, and the 3rd, cable installation in pipe.The feature of directly buried installation is good heat dissipation, easy construction, and small investment, but maintenance is inconvenient, the perishable and extraneous mechanical damage of generation; Although it is convenient that cable tunnel lays, take that the underground space is large, cost is high; And adopt drawing-in wire to lay, and construction is simple, reduced investment, and maintenance is convenient, can be pre-buried in advance, can avoid the impact of underground other pipeline on cable itself.The use amount of cable protection pipe in power grid construction and improvement project grows with each passing day, but cable protecting sleeve kind is a lot, and performance is different, therefore the selection outbalance of cable protecting sleeve.
The kind of cable protecting sleeve mainly contains several like this classes: high-molecular organic material cable protection pipe, and as carbon element bellows, pvc pipe etc.Class of metal materials cable protection pipe, as plastic-coated steel, coating steel pipe etc.Resin base fiber reinforced composite material class cable protection pipe, as glass reinforced plastic pipe etc.Cement based fibre reinforced composites class cable protection pipe, as low friction fibre-cement pipe, polyvinyl pipe of cement etc.
Current cable protecting sleeve; structure; substantially be all a kind of ring sleeve with single aperture; in the time of construction; substantially a cable protecting sleeve is a separately protected cable, and protection is simultaneously much more rare with cable, even if having; substantially in a cable protecting sleeve, can not exceed 3 cables, this has formed very large waste.
Therefore, in order to meet the demand in market, for socioeconomic development, realize the demand of conservation-minded society development, be necessary, develop and a kind ofly novel can protect many power cable protecting pipes with cable simultaneously.
Summary of the invention

Technical scheme: in order to realize above object, the utility model by the following technical solutions.
A kind of type ground-buried power cable protecting pipe, comprise body, described body inside is provided with at least one isolation strip, the passage in described body is divided at least two independently passages by described isolation strip, described isolation strip comprises two-layer PE layer, be respectively PE layer one and PE layer two, between described PE layer one and PE layer two, be provided with the screen one of shielded signal, the inwall of described body is interior PE layer, the outer wall of described interior PE layer is provided with screen two, the outer wall of described screen two is provided with outer PE layer, the outer wall of described outer PE layer is provided with waterproof anti-corrosion layer, the outer wall of described waterproof anti-corrosion layer is provided with rigid layer.The utility model is divided into multiple passages by isolation strip by body, like this, a cable protecting sleeve just can be protected many with cable simultaneously, save material and space, also avoided being equipped with in a protective casing many with cable simultaneously, between cable, interfere with each other, thereby the situation of poor signal is occurred; Meanwhile, in isolation strip, be provided with screen, can prevent the cable in pipeline, expose inner lead just in case the cable wherein having is aging, can disturb the situation of the signal of other cables to occur; The outer wall of body is provided with screen, can prevent that the cable of sleeve pipe and inside pipe casing from interfering with each other signal; Be provided with waterproof anti-corrosion layer, can protective casing, prevent because being embedded in for a long time the underground corrosion that is subject to water and other corrosive substances; Rigid layer has increased the impact resistance of sleeve pipe, can also prevent that sleeve pipe from affecting the protective effect of sleeve pipe because being subject to the biting of biology such as underground worm ant simultaneously.
Described screen one, screen two are aluminium-plastic tape, and described screen one, screen two thickness are 0.1-0.2mm.
Described waterproof anti-corrosion layer is polytetrafluoroethylene floor, and the thickness of described waterproof anti-corrosion layer is 0.8-1.2mm.Polytetrafluoroethylene floor has splendid waterproof, anticorrosive property, has the feature of antiacid alkali resistant, anti-various organic solvents, and performance is very stable, harmless environmental protection simultaneously.
Described rigid layer is the one in 12 layers of nylon, high-density polyethylene layer, CPVC layer, and the thickness of described rigid layer is 0.6-0.8mm.Above material, its rigidity is all splendid, to the protective effect of sleeve pipe which, simultaneously environmentally friendly.
The inner wall smooth of described body, the outer wall of described body is provided with helical corrugation.Inner wall smooth can prevent that the cable of inwall is impaired, and outer wall is provided with helical corrugation, can increase frictional force, anti-skidding, uses convenient.
Beneficial effect: the type ground-buried power cable protecting pipe that the utility model provides compared with prior art, has the following advantages:
1, power cable protecting pipe of the present utility model, by isolation strip, body is divided into multiple passages, like this, a cable protecting sleeve just can be protected many with cable simultaneously, save material and space, also avoid, in a protective casing, the cables of following are housed more simultaneously, between cable, interfered with each other, thereby the situation of poor signal is occurred; Meanwhile, in isolation strip, be provided with screen, can prevent the cable in pipeline, expose inner lead just in case the cable wherein having is aging, can disturb the situation of the signal of other cables to occur; The outer wall of body is provided with screen, can prevent that the cable of sleeve pipe and inside pipe casing from interfering with each other signal; Be provided with waterproof anti-corrosion layer, can protective casing, prevent because being embedded in for a long time the underground corrosion that is subject to water and other corrosive substances; Rigid layer has increased the impact resistance of sleeve pipe, can also prevent that sleeve pipe from affecting the protective effect of sleeve pipe because being subject to the biting of biology such as underground worm ant simultaneously;
2, power cable protecting pipe of the present utility model, the material that tubing uses is all asepsis environment-protecting material, makes the environmentally safe of tubing own.
