通号线缆地下管线非开挖定向穿越铁路施工技术研究

Non-open-cut Directional Drilling Technology in Underground Construction of Signal and Communication Pipelines and Cables

在既有线铁路施工中,非开挖定向穿越敷设M P P地下管线技术,解决了传统明挖施工对交通、环境和周边建筑物基础的干扰,并具有施工速度快,工程精度高,劳动强度低,材料消耗小,敷设距离长,施工安全性好等优点。该技术不仅在应用中取得实际的经济效益,同时取得安全施工生产的社会效益。值得在今后"通信、信号"地下管线非开挖地段敷设施工中推广和应用。

During construction of existing railways, the MPP non-open-cut directional drilling technology has more advantages than traditional open-cut technology such as little interference to traffic, environment and buildings surround, quick construction, high precision, low labor intensity, material saving, long- distance laying and construction safety etc. This technology has both economic and social benefits in its application and it is worthy to be popularized and applied in non-open-cut construction of signal and communication pipelines and cables in the future.
