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
