非开挖定向钻孔敷设电力电缆的施工实践

Practice of directional hole boring for laying electric power supply lines

介绍了某35 kV送电线路工程采用非开挖定向钻孔技术进行YJV62-35 1×300电力电缆穿越城区敷设施工的方法。该方法在保护地面设施的前提下,避开地下管线,实现了在一些无法实施开挖作业的地区敷设电力电缆。

This paper introduces the application of non surface duct digging directional underground hole boring technology for a certain 35kV power line project. Under the precondition of protecting the surface structures and avoiding other utility pipes and lines underneath the ground surface, the project of YJV62-35 1 × 300 power line penetrating the urban area is carried out. This practice realizes the laying of electric power supply lines in areas where open duct digging is not practical.
