Description
Technical field
The invention belongs to pipe technology field, especially relate to a kind of for laying the pipeline of air-blowing cable.
Background technology
Along with the develop rapidly of the industries such as electric power, communication, the amount of laying of cable is more and more, and because in the past a large amount of cables adopts built on stilts laying, therefore, aerial cable is very in disorder, has affected city look and feel, meanwhile, has brought great potential safety hazard; For this reason, country has promulgated corresponding law, rules and instruction, need to adopt into the mode on ground and lay for cable.Cable mainly contains poling and direct-buried mode in underground laying, and direct-buried mode need to be dug ground, and needs multiple tracks examination and approval procedures, therefore, cumbersome; For this reason, pipeline laying mode will be after the principal mode of underground laying.
In the underground larger caliber pipeline having laid, the cable of and smooth in appearance less for diameter, while having sufficient space in pipeline, can directly carry out tractive lays, but, tractive cable laying operation progress affects the quality of cable more slowly and easily, especially optical cable, once the quality of cable is impaired in construction, just very huge by the cost of cable taking-up or restorability.
For larger city, existing conduit resource pretty nervous, rents the pipeline of the about 18mm diameter of 1KM conventionally, and annual price is 200,000 yuan of left and right, therefore, quite expensive.
For this reason, expect to have good solution in industry, can in the underground pipeline that has an excess room, carry out laying of cable, no matter whether this inner-walls of duct is quite smooth.
Summary of the invention
In order to address the above problem, the object of the invention is to disclose a kind of for laying the pipeline of air-blowing cable, during use, the present invention is inserted in the underground pipeline having laid or directly imbeds underground, then adopt air blowing device that cable is blown in the present invention, the performance quite stable of cable in the very fast and laid processes of construction schedule; The present invention realizes by the following technical solutions.
For laying a pipeline for air-blowing cable, it is characterized in that it includes tube body 1, on the inwall of tube body, there are a plurality of guiding gutters 2, the inside of tube body has the passage 3 of hollow, is isolated bar 4 and separates between adjacent guiding gutter.

In the present invention, when there is no raised line, interior tube body and outer tube body can be by bonding formation; Or outer tube body is coated on outside interior tube body by extrusion molding.
Adopt the present invention to carry out laying optical cable for laying the pipeline of air-blowing cable, guiding gutter be shaped as triangular prism shape, outer diameter tube 14mm, channel diameter are 12mm, the number of guiding gutter is 15, the diameter of optical cable is 11.8mm, core number is 288 cores, adopt commercially available GJ-60 type air-blowing machine to carry out air-blowing test, blast pressure is 0.3bar, the time that 1KM optical cable has been worn this pipeline is 2 hours, personnel are three people, one man operation machine, and a people is guard's cable discharging disc tool, one people looks for the pipeline other end follows, the attenuation coefficient of all optical fiber in detection optical cable after air-blowing completes, detects at 1310nm and 1550nm window, and attenuation change absolute value is all less than 0.03dB/km, and adopt pipeline of the prior art, external diameter 14mm equally, internal diameter 12mm, three staff equally, air-blowing 30 meters just cannot carry out, and air-blowing 30 popped rices 1 hour 20 minutes, due to without guiding gutter, air-blowing machine cannot be proceeded, therefore, use instead manually and lay, that 3 people lay equally, spent 95 hours and just worn, worn the attenuation coefficient of all optical fiber in rear detection optical cable, at 1310nm and 1550nm window, detect, at 1550nm window, there is the decay of 236 cores to increase over 0.25dB/km, there is the decay of 48 cores to increase over 0.15dB/km, only there is the decay increase of 4 cores to be no more than 0.03dB/km, 284 core fibres cannot be used at 1550nm window, at 1310nm window, there is the decay of 222 cores to increase over 0.15dB/km, there is the decay of 49 cores to increase over 0.10dB/km, there is the decay increase of 17 cores to be no more than 0.03dB/km, 271 core fibres cannot be used at 1310nm window.
When adopting above-mentioned pipeline of the present invention, only the number of guiding gutter is 30, through test, has only used 1 hour 45 minutes, and 1310nm and 1550nm window detect, and attenuation change absolute value is all less than 0.025dB/km.
Through overtesting, when the number of guiding gutter increases, it is easier to lay, and the attenuation change of optical fiber is less.
Certainly, while adopting spiral helicine guiding gutter, laying speed is faster, and the attenuation change of optical fiber is less.
In the present invention, due to the existence of guiding gutter, even if cable diameter is close with channel size, during air-blowing, air-flow, by the guiding of guiding gutter, can be delivered to destination easily and quickly by cable; Certainly, cable diameter is than channel size hour, more easily air-blowing cable; When guiding gutter is borded pile shape, be more conducive to blow cable, blow efficiency higher; On arbitrary cross section, when the part that many isolating bars contact with passage is positioned on same circumference, cable blows convenient, can be suitable for various cables; When being inlaid with color on the outer wall of tube body or on the outer wall of outer tube body and differing from the identification strip of tube body, can be used in the pipeline that lays air-blowing cable and more easily be identified; Certainly, while thering is groove on the outer wall of tube body or on the outer wall of outer tube body, can be used in the pipeline that lays air-blowing cable and more easily be identified; In the present invention for laying the pipeline of air-blowing cable, outer tube body and interior tube body can be bonded together, and certainly, on the outer wall of interior tube body, can also have at least one raised line, and raised line is embedded in outer tube body, this mode makes inside and outside body in conjunction with more firm.The pipeline with interior tube body and outer tube body is more wear-resisting, and after outer tube body breakage, the moisture content also utmost point is not easy to enter in interior tube body, therefore, better for the protective value of cable.
In the present invention, can low sticky end oil or water be first blown in passage, low sticky end oil or water will be dispersed in guiding gutter, when air-blowing cable, gas blows out low sticky end oil or water from guiding gutter, greatly reduces, certainly for the frictional force on cable surface, even if do not add low sticky end oil or water, also can lay easily and quickly cable and not affect the performance of cable; Therefore can more effectively utilize conduit resource.
The present invention has following main beneficial effect: simple in structure, easy-formation, lay cable efficiency higher and lay more convenient, more can rationally utilize conduit resource, can save in a large number the lease expenses of pipeline.
The present invention is suitable for optical cable, cable, photoelectricity is compound or the air-blowing of photoelectric mixed cable, in same passage, can blow many cables.
The present invention is not limited to above-mentioned preferred forms, should be appreciated that design of the present invention can be by other various forms enforcement utilizations, and they drop in protection scope of the present invention equally.
