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; Certainly, even if there is no guiding gutter in the application, as embodiment 1, as long as the inwall smooth enough of interior tube body also can be used the air-blow technology to enter the Quick distributor of cable easily.
In the present invention, owing to thering is self-supporting body, and there is reinforcement in self-supporting body, there is quite high tensile strength, and if adopt many separated reinforcements can increase load reliability, but can increase the difficulty of production and the speed of production; Pipeline cloth of the present invention is placed in the pipelines such as rainwater or sewage, then at adjacent people's well head, be fixed, pipeline of the present invention is placed in the pipelines such as rainwater or sewage with the mode cloth of self-supporting, get final product air-blowing cable easily, can greatly save lease pipeline fee with and more reasonably utilize existing conduit resource, save widely construct, construction cost.
The present invention not only can be used in underground pipeline, can also built on stilts mode lay, the present invention is adopted to the built on stilts mode of laying of prior art cable, lay aloft, as long as passage is enough large, after cloth discharges the present invention, if desired lay other cable, only need to adopt the mode of air-blowing, can easily many cables be sent in passage, therefore greatly saved the time laying, and it be attractive in appearance, no longer in disorder to lay rear circuit.
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 pipeline and space resources, can save in a large number lease expenses and the operating 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.
