Abstract
A method for laying a benzene hydrogenation engineering direct-buried cable is characterized by comprising the following steps: a, performing levelling along a laying path of the direct-buried cable; b, after laying of the cable, laying a soft soil or sand layer having the thickness greater than 100mm at the upper part of the cable; c, tamping backfill in layers before backfilling the direct-buried cable; and d, providing obvious azimuth marks or stakes at positions of a linear segment of the direct-buried cable at intervals of 50-100m, cable connectors, corners and buildings. The method for laying the benzene hydrogenation engineering direct-buried cable provided by the present invention has the advantages of reasonable design for manufacturing steps, simple operation, safe and reliable engineering quality, excellent electrical performance and reduced engineering cost.
Description
Technical field
The present invention relates to a kind of cable laying method of electric equipment, specifically, is a kind of laying method of benzene hydrogenation engineering direct-buried cable.
Background technology
The technique of benzol hydro refining unit is more special, its system complex, and equipment is many, and the pressure of system own, temperature are higher, and pumping unit does not allow idle running.Benzene hydrogenation engineering be mainly divided into central control room and electric substation, refining plant, water supply and sewage work, air compression station, storage and handling facility (tank field and pump house), full factory powers and the illumination of full factory, torch and engineering affiliated facility, in the electrical install of these facilities, have lightning protection, fire prevention, explosion-proof particular/special requirement, wherein laying of cable is important step in whole electrical system.Current domestic built or be still in the stage lack of standardization the laying of cable of building benzene hydrogenation engineering equipment, there is a lot of not science, irrational place, manufacturing process is numerous and diverse, manufacturing cost is high.
The laying method of therefore known benzene hydrogenation engineering direct-buried cable also exists above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is the laying method proposing a kind of safe and reliable benzene hydrogenation engineering direct-buried cable.
For achieving the above object, technical solution of the present invention is:
A laying method for benzene hydrogenation engineering direct-buried cable, is characterized in that comprising the following steps:
A, need smooth along the path laid of direct-buried cable, not sharp-pointed outstanding hard foreign material, cable lay sand bed or the weak soil that trench bottom lays more than 100mm thickness; Channel depth is that the distance on cable surface distance ground is not less than 0.7m, and channel depth when passing through farmland is that the distance on cable surface distance ground is not less than 1m;
After b, cabling, repave on cable top to be greater than the thick weak soil of 100mm or sand bed, and add a cover baffle, cover width is for exceeding each 50mm in cable both sides;
Compaction in layers backfill soil before c, backfill direct-buried cable;
The straightway of d, direct-buried cable will arrange obvious bearing marker or stake every 50 ~ 100m place, cable connector place, turning, building place etc.
The laying method of benzene hydrogenation engineering direct-buried cable of the present invention can also be further achieved by the following technical measures.
Aforesaid method, wherein also comprises the safeguard measure preventing cable to be subject to the harm such as mechanical injuries, chemical action, underground current, vibration, thermal impact, corrosive deposit, worm mouse.
After adopting technique scheme, the laying method of benzene hydrogenation engineering direct-buried cable of the present invention has the following advantages:
1, making step is reasonable in design, simple to operate;
2, safe and reliable, the excellent electric properties of project quality;
3, engineering cost is reduced.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
