GPS在长输管道同沟光缆施工中的应用

近年来,油气田光缆施工大多采用与长输管道同沟敷设方式,但因征地、跨越农田地段和穿越等复杂多变环境,管道施工经常采用跳跃式施工,光缆自然不可能实现按顺序连续敷设。采用传统测量方式,耗时、效率低、误差大。如采用GPS测量方式,既能达到精确配盘保证施工质量,又能减轻劳动强度、减少作业时间,同时节省材料降低施工成本,且形成的数字化资料对用户今后光缆巡线、抢修和维护也都十分方便。

Application of GPS in Laying Canble and Pipeline into the Same Ditch

In recent years, the fiber cable construction in the oil and gas fields always use the way of laying the cable and the long-distance pipeline into the same ditch which may set underground. For the reason of land acquisition and the complex environments in construc- tion sites, the cable can not be continuous set in order because of the pipeline can not be set successively during constrction. Using the traditional measurement, it may has the shortage of time-consuming, inefficient and large error. The GPS measurement can take precise ar- rangements, quickly examining the location of joint pit, reducing construction time, saving material and construction cost. The circuit stick＇s numbers and the joint pit coordinates can give lots of help to the cable＇s tour-line,repair, and maintenance.
