Abstract
The invention discloses a communication optical cable separate laying method between a No.1 pumping station and a water supply station. Two 24-core optical cables are separately laid between the No.1 pumping station and the water supply station. In a non-rock stratum, the optical cable sleeved by a silicon core pipe is directly laid at a bottom of an excavated furrow; the furrow is backfilled by fine soil to be within a range of 100mm to 120mm; the furrow is then backfilled by undisturbed soil above the fine soil, the undisturbed soil is within a range of 100mm-120mm, and an optical cable sign tape is laid in the undisturbed soil; the undisturbed soil is used for backfilling around the optical cable sign tape till a stratum surface; and a full length of the optical cable is about 4km. The fact that no coal conveying pipeline exists between the No.1 pumping station and the water supply station enables the pipeline laying of the invention to be different from the pipeline laying in the same furrow, so that the special excavated furrow and the separate laying are required. The optical cable is laid through the excavated furrow and being sleeved by the silicon core pipe; the method has the following advantages: the method is free of large equipment, simple in process, easy in construction and little in investment; the cost and labor hour are saved; and the method can be widely applied to the field communication optical cable separate laying industry. The method is also suitable for the laying of various pipelines in the soil stratum.
Description
Technical field
The invention belongs to convey coal pipe communication system circuit, be specifically related to No. 1 pumping plant to the independent laying method of communications optical cable between the water stop.
Background technology
Current, that communications optical cable generally has is built on stilts, pipeline and 3 kinds of system of layings of direct-burried.Though it is minimum and simple that the mode of wherein making somebody a mere figurehead drops into, key obstacle is that ready-made electric pole will be arranged, and the right to use of necessary live wire bar; In case directly buried installation mode later stage optical cable breaks, have operations such as the omnidistance excavation of secondary when needing maintenance, thereby this system of laying later maintenance is existed to have high input, and time-consuming defective.
Summary of the invention
The purpose of this invention is to provide a kind ofly based on the loess stratum, adopt ditching to wear silicon core pipe and lay No. 1 pumping plant to the independent laying method of communications optical cable between the water stop.
In order to overcome the deficiencies in the prior art, technical scheme of the present invention is to solve like this: No. 1 pumping plant is to the independent laying method of communications optical cable between the water stop, this laying method comprises laying under the 2 kinds of situations in non-lithostratigraphy and lithostratigraphy, it is characterized in that being undertaken by following step:
One, in non-lithostratigraphy, lay step:
1), in non-lithostratigraphy, optical cable directly is laid in the bottom of trench of excavation;
2), be backfilled to 100 ㎜～120 ㎜ with fine earth;
3), on the fine earth backfill, be backfilled to 100 ㎜～120 ㎜ with undisturbed soil again, optical cable colored belt of laying in undisturbed soil;
4), around the optical cable colored belt again backfill undisturbed soil to surface of stratum;
Two, in the lithostratigraphy, lay step:
1), in the lithostratigraphy, earlier in bottom of trench, be backfilled to 100 ㎜～120 ㎜ with fine earth;
2), on the fine earth backfill, choose the ditch laying optical cable;
3), the thick fine earth of backfill 95 ㎜～120mm on optical cable;
4), on backfill backfill undisturbed soil to 100 ㎜～120 ㎜, in undisturbed soil, lay an optical cable colored belt;
5), around the optical cable colored belt again backfill undisturbed soil to surface of stratum.
The present invention compared with prior art, based on the loess stratum, adopt ditching to wear the method that silicon core pipe lays, the key distinction of scheme is, in non-lithostratigraphy, optical cable can directly apply and be put in bottom of trench, and in the lithostratigraphy, respectively spread the fine earth that 100 ㎜～120 ㎜ are thick on bottom of trench and optical cable, and then backfill undisturbed soil, drop into little, cost saving and man-hour, the extensively industry of laying separately with open-air communications optical cable.
The control parameter of putting sloping ditching sees Table 1.
Table 1 is put the depth H and the ratio of putting a sloping side width D of sloping ditching
Description of drawings
Fig. 1 lays sectional drawing separately for non-lithostratigraphy optical cable;
Fig. 2 lays sectional drawing separately for the lithostratigraphy optical cable;
Among the figure, 1 is undisturbed soil; 2 is the optical cable colored belt; 3 is communications optical cable; 4 is fine earth; H is the fiber cable laying degree of depth; D is for putting a sloping side width.
Embodiment
Below in conjunction with drawings and Examples summary of the invention is described further:
With reference to Fig. 1, shown in Figure 2, No. 1 pumping plant is to the independent laying method of communications optical cable between the water stop, and this laying method comprises laying under the 2 kinds of situations in non-lithostratigraphy and lithostratigraphy, it is characterized in that being undertaken by following step:
One, in non-lithostratigraphy, lay step:
1), in non-lithostratigraphy, optical cable 3 directly is laid in the bottom of trench 4 of excavation;
2), be backfilled to 100 ㎜～120 ㎜ with fine earth;
3), on the fine earth backfill, be backfilled to 100 ㎜～120 ㎜ with undisturbed soil 1 again, optical cable colored belt 2 of laying in undisturbed soil;
4), around optical cable colored belt 2 again backfill undisturbed soil 1 to surface of stratum;
Two, in the lithostratigraphy, lay step:
1), in the lithostratigraphy, earlier in bottom of trench 4, be backfilled to 100 ㎜～120 ㎜ with fine earth;
2), on the fine earth backfill, choose ditch laying optical cable 3;
3), the thick fine earth of backfill 95 ㎜～120mm on optical cable 3;
4), on backfill backfill undisturbed soil 1 to 100 ㎜～120 ㎜, in undisturbed soil, lay an optical cable colored belt 2;
5), around optical cable colored belt 2 again backfill undisturbed soil 1 to surface of stratum.
Embodiment 1
In non-lithostratigraphy, optical cable 3 can directly be laid in bottom of trench, and in the lithostratigraphy, respectively spreads the fine earth that one deck 100 ㎜～120 ㎜ are thick on bottom of trench and optical cable 3, and also can be considered as the bottom of trench degree of depth optical cable buried depth this moment.
Optical cable 3 buried depths must satisfy the natural ground of distance and be not less than 1.2m, must satisfy being embedded in below the frozen soil layer simultaneously; Buried depth should be not less than 1.2m apart from the side drain bottom of trench during excavation road crossing; 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.
