Abstract
The utility model relates to a MPP power cable protection tube, mainly used installation power cable or communication line. This MPP power cable protection tube, including outer pipe wall, characterized by still includes interior tube core, interior tube core suit is outside in the pipe wall, the outer evenly distributed of interior tube core has a plurality of interior space stop bars that support. This product is built -in to have the interval, but the pipeline of the different specifications of cross -under, and each other do not influence, have interior support simultaneously, guaranteed the inner structure intensity and the whole crookedness of product, it is also very convenient to keep in repair and disassemble, and all kinds of pipelines of tube core are surveyability in taking out.
Description
Technical field
The utility model relates to a kind of MPP power cable protecting pipe, is mainly used in installing power cable or communication line.
Background technology
Along with China is to the growth of electricity needs, electric utility obtains high speed development, and corresponding is with it that the consumption of the power pipe of supporting practicality also increases with day.Existing power pipe is generally hollow cylindrical, normally cable is worn and use in the duct, but along with the problem of power pipe service life, some problems will come out: power pipe Long Term Contact rainwater or sewage, the outside of power pipe can receive serious corrosion, cable inside serious threat, have impact on the useful life of cable.
In prior art, MPP power pipe adopts modified polypropene to be main raw material(s), need not dredge in a large number, cuts the earth and destroy road surface, all having application in construction works such as road, railway, building, the inferior Special zone roughing-in in riverbed, cables when applying.Compared with traditional " grooving pipe laying method "; no-dig technique power pipe engineering more adapts to current environmental requirement; remove because of traditional construction cause stir up a cloud of dust, the factor that disturbs residents such as traffic jam; this technology can also cannot implement the regional pipeline installation excavating operation, as paleovolcanic structure district, business district, crops and farmland protection area, highway, river etc. at some.
Antipriming pipe has very strong compatibility and usability, and it is applicable to the wearing of many cables such as optical cable, cable, coaxial cable, PCM cable and puts, and is widely used in telecommunications, broadcasting and TV, railway, army, universities and colleges, the intercommunication of big-and-middle-sized industrial and mining enterprises etc.
Current MPP power pipe has solid wall pipe and bellows two, and only has solid wall pipe for trenchless engineering.Therefore, the Development and Production of antipriming pipe will be the product that no-dig technique pipeline updates, and can recognize, increase work efficiency to many optical cables, form in the clandestine network world of nest of tubes at plum tube and bellows, no-dig technique antipriming pipe will be prospect and the inexorable trend of the development of communication pipeline.
Utility model content
The utility model object is to provide one to solve the above-mentioned problems in the prior art, and what be applicable to many cables such as optical cable, cable, coaxial cable, PCM cable wears the MPP power cable protecting pipe put.
The utility model object is achieved through the following technical solutions:
A kind of MPP power cable protecting pipe; comprise outer tube wall; it is characterized in that; also comprise interior tube core; interior tube core is sleeved in outer tube wall; some inner support spacer bars are evenly distributed with outside described interior tube core; described inner support spacer bar contacts with the medial surface of outer tube wall; and inner support spacer bar extends along the axis direction of outer tube wall; the cross sectional shape of described interior tube core is annulus, and the inner circle of described annulus is 1: 2 with the ratio of exradius, is provided with reinforcement in annulus; reinforcement is uniformly distributed, and extends along the axis direction of interior tube core.
As preferably, described inner support spacer bar is provided with six.
As preferably, described reinforcement has three, in 120 degree of angular spacings distributions.
As preferably, described interior tube core, inner support spacer bar and reinforcement are integrated.
As preferably, described outer tube wall is modified polypropylene material.
Compared with prior art, this product has the following advantages: this product is built-in with interval, can the pipeline of cross-under different size, and is independent of each other, and simultaneously with inner support, ensure that inner structural strength and the Integral bending curvature of product; Maintenance and disassemble also very convenient, all kinds of pipeline of tube core and very clear in extracting out; This product is no-dig technique tubing, without the need to excavation construction, little to ground traffic impact, both ensure that the reliability of pipe network, and has reduced the failure rate of pipe network, also makes city appearance environment be greatly improved simultaneously; Main is raw material with modified polypropene, has excellent electric insulating quality, higher heat distortion temperature and low temperature impact properties, and light weight, smooth, frictional resistance is little, can thermofussion welding docking.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model embodiment cross section.
Label declaration: outer tube wall 1, interior tube core 2, inner support spacer bar 3, reinforcement 4.
Embodiment
Below in conjunction with specific embodiment, the utility model is described, the following example, only for illustration of the technical solution of the utility model, does not limit protection range of the present utility model.
Embodiment one:
As shown in Figure 1, the product of the present embodiment comprises outer tube wall 1 and interior tube core 2, interior tube core 2 is sleeved in outer tube wall 1, and be evenly distributed with some inner support spacer bars 3 outside interior tube core 2, inner support spacer bar 3 contacts with the medial surface of outer tube wall 1, and inner support spacer bar 3 extends along the axis direction of outer tube wall 1, the cross sectional shape of interior tube core 2 is annulus, and the inner circle of annulus is 1: 2 with the ratio of exradius, is provided with reinforcement 4 in annulus, reinforcement 4 is uniformly distributed, and extends along the axis direction of interior tube core 2.
The inner support spacer bar 3 of the present embodiment is provided with six, and reinforcement 4 has three, in 120 degree of angular spacing distributions.Interior tube core 2, inner support spacer bar 3 and reinforcement 4 are integrated, and outer tube wall 1 is modified polypropylene material.
In actual use procedure, interval in the medial surface of this product inner support spacer bar 3 and outer tube wall 1 contacts and forms, can the pipeline of cross-under different size, and is independent of each other, and simultaneously with inner support, ensure that inner structural strength and the Integral bending curvature of product; Maintenance and disassemble also very convenient, all kinds of pipeline of tube core 2 and very clear in extracting out; This product is no-dig technique tubing, without the need to excavation construction, little to ground traffic impact, both ensure that the reliability of pipe network, and has reduced the failure rate of pipe network, also makes city appearance environment be greatly improved simultaneously; Main is raw material with modified polypropene, has excellent electric insulating quality, higher heat distortion temperature and low temperature impact properties, and light weight, smooth, frictional resistance is little, can thermofussion welding docking.
Be only several specific embodiments of the application above, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drops in the protection range of the application.
