Abstract
The invention discloses a method for laying a long-distance coal delivery pipeline and communication optical fiber cables in one ditch, which includes the three types, namely laying cables in a non-rock stratum with the depth less than 5 mm, laying cables in a non-rock stratum with the depth more than 5 mm, and laying cables in a rock-soil stratum, and mainly relates to steps of relative position, horizontal spacing, depth and construction of the cables and the coal delivery pipeline when the coal delivery pipeline and the cables are laid in one ditch. According to the invention, the coal delivery pipeline and the cables are laid in one ditch, the excavated volume is reduced, the construction period is shortened, labor and time are saved, and the method can be widely applied in the pipeline transportation industry.
Description
Technical field
The invention belongs to convey coal pipe and communications system line arrangement, be specifically related to long method apart from convey coal pipe and communication optical cable laying in one ditch.
Background technique
Defectives such as existing communication optical cable lays and is single directly buried type, does not have special requirement, if single directly buried type method is applied to the present invention, exists the human and material resources waste big, and is long in time limit.
Summary of the invention
The purpose of this invention is to provide a kind of saving human and material resources, the single relatively directly buried type duration is short, excavates the little length of workload apart from the method for convey coal pipe and communication optical cable laying in one ditch.
In order to overcome above-mentioned deficiency, technological scheme of the present invention is to solve like this: long method apart from convey coal pipe and communication optical cable laying in one ditch, and this method is carried out according to the following steps:
1), the convey coal pipe buried depth is apart from ground surface 2m～5m;
2), optical cable is positioned at the convey coal pipe both sides, and is and concordant with the convey coal pipe top, is not less than 300mm with the horizontal clear distance of convey coal pipe tube wall; Be not less than 1.2m apart from the natural ground degree of depth, will satisfy being embedded in the following requirement of frozen soil layer simultaneously;
3), excavation is during highway crossing, buried depth is not less than 1.2m apart from the side drain bottom of trench; When passing through irrigation canals and ditches, pool, buried depth should be at dredging or the following 1.2m of the plan degree of depth that dredges; When passing through streams etc. and being subject to wash away the location, buried depth should be at the following 1.2m of erosion line;
4), optical cable static buckling least radius is 10 times of cable outer diameters, the dynamic bending least radius is 20 times of cable outer diameters;
5), the step of laying of optical cable is: convey coal pipe elder generation hyposulculus lays, the part backfill is to the convey coal pipe top, choose the twice ditch in the place that the horizontal clear distance of convey coal pipe tube wall is not less than 300mm then, lay again in the silicon core pipe and wear optical cable, 300mm laying optical cable colored belt above silicon core pipe is backfilled to the face of land at last greatly.
The distance of described convey coal pipe bottom surface and bottom of trench is 180 ㎜～210 ㎜, and the distance of convey coal pipe top and optical cable colored belt is 300 ㎜.
The distance of described convey coal pipe bottom surface and bottom of trench is 0 ㎜, and the distance of convey coal pipe top and optical cable colored belt is 300 ㎜.
The invention has the beneficial effects as follows: at least 2 24 core optical fiber cable for direct burials of laying in one ditch, the lightguide cable link total length is 727km at least, and optical cable and convey coal pipe laying in one ditch can reduce excavated volume, shorten the construction period, the saving of labor, save time, and are widely used in the pipeline transport industry.
