Abstract
The utility model discloses a cable calandria structure, the basement sets up in calandria passageway bottom in advance, calandria passageway upper portion is equipped with the apron, the cable calandria sets up in the calandria passageway, the cable is placed in the cable calandria, the interval equals between the adjacent cable calandria, it places the pipeline to be equipped with the backward flow line around the cable calandria, the backward flow line is put in the pipeline is placed to the backward flow line, adjacent backward flow line is placed and is had crossing part between pipeline and the cable calandria and intersect the diameter that nodical straight -line distance is less than the line that flows back, provided is a novel cable calandria structure, it places the pipeline to be equipped with the backward flow line of placing the backward flow line specially, moreover, the steam generator is simple in structure, therefore, the clothes hanger is strong in practicability.
Description
Technical field
The utility model relates to technical field of civil engineering, particularly relates to a kind of novel cable calandria structure.
Background technology
The demand of development to electric energy in city is growing, how when not affecting urban look and space utilization, electric energy safe is sent to smoothly the every nook and cranny in city, putting cable underground is the most direct the best way, and for making outside cable circuit from the injury such as mechanical damage, chemical corrosion, cable laying has just become the most frequently used a kind of scheme in cable duct bank.Exchange metallic sheath or the screen of single-core cable, circuit has a bit direct ground connection at least, under the direct Grounding of single-point during system short-circuit, metal level line-frequency induction voltage can exceed cable sheath insulation withstand strength or shield voltage limiter industrial frequency withstand voltage intensity, and therefore needing needs to arrange return wire when suppressing cable to close on light current circuit electrical Interference intensity.Current cable by comb lay add return wire time often return wire need the position, comb hole outside occupying volume, cause the occasion wasting of resources to a certain degree of position, original hole anxiety.
Therefore, those skilled in the art is devoted to develop a kind of cable duct bank structure, and be provided with the special return wire placing return wire and place pipeline, structure is simple, practical.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of cable duct bank structure, and be provided with the special return wire placing return wire and place pipeline, structure is simple, practical.
For achieving the above object, the utility model provides a kind of cable duct bank structure, comprise cable and cable duct bank, comb passage, cover plate, substrate, substrate is pre-set at comb channel bottom, comb channel upper is provided with cover plate, cable duct bank is arranged in comb passage, cable is positioned in cable duct bank, between adjacent cable comb, interval is equal, be provided with return wire around cable duct bank and place pipeline, return wire is put in return wire and places in pipeline, adjacent return wire is placed exists intersection between pipeline and cable duct bank and the air line distance intersecting intersection point is less than the diameter of return wire.
Further, the material of cable duct bank and return wire placement pipeline is plastic material or HBB glass reinforced plastic pipe;
Further, the inner pore diameter range of cable duct bank is 150mm-175mm;
Further, the diameter of return wire placement pipeline is less than the diameter of cable duct bank;
Further, cover plate is steel reinforced concrete cover plate.
The beneficial effects of the utility model:
The utility model designs due to said structure, substrate is pre-set at comb channel bottom, comb channel upper is provided with cover plate, cable duct bank is arranged in comb passage, cable is positioned in cable duct bank, between adjacent cable comb, interval is equal, be provided with return wire around cable duct bank and place pipeline, return wire is put in return wire and places in pipeline, adjacent return wire is placed exists intersection between pipeline and cable duct bank and the air line distance intersecting intersection point is less than the diameter of return wire, a kind of novel cable calandria structure is provided, be provided with the special return wire placing return wire and place pipeline, structure is simple, practical.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the specific embodiment of a kind of cable duct bank structure of the utility model, comprise cable 1 and cable duct bank 2, comb passage 3, cover plate 4, substrate 5, described substrate 5 is pre-set at bottom comb passage 3, comb passage 3 top is provided with cover plate 4, cable duct bank 2 is arranged in comb passage 3, cable 1 is positioned in cable duct bank 2, between adjacent cable comb 2, interval is equal, be provided with return wire around cable duct bank 2 and place pipeline 6, return wire 7 is put in return wire and places in pipeline 6, adjacent return wire is placed exists intersection between pipeline 6 and cable duct bank 2 and the air line distance intersecting intersection point is less than the diameter of return wire 7.
The technical scheme that the utility model is optimized further, the material that described cable duct bank 2 and return wire place pipeline 6 is plastic material or HBB glass reinforced plastic pipe, the inner pore diameter range of described cable duct bank 2 is 150mm-175mm, the diameter of described return wire placement pipeline 6 is less than the diameter of cable duct bank 2, and described cover plate 4 is steel reinforced concrete cover plate.
Current cable duct bank aperture is generally 150mm-175mm, consider to adopt a kind of novel cable calandria structure, cable duct bank 2 circumference increases by one and meets the pipeline that return wire 7 places requirement and corresponding normality condition, adjacent return wire is placed exists intersection between pipeline 6 and cable duct bank 2 and the diameter that the air line distance intersecting intersection point is less than return wire 7 leaves certain surplus, ensure that return wire 7 can not be fallen in cable duct bank 2, the visible Fig. 1 of its specific constructive form, this form can solve the problem that return wire additionally accounts for cable duct bank 2, improve the utilance of cable duct bank 2, reduce the position wasting of resources of cable duct bank 2 hole.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection range of claims.
