Cable Laying Technology in Trenchless Channel

With the rapid economic development, urban construction has become saturated and the usable space is becoming increasingly narrow. The construction of overhead transmission lines occupies a lot of land resources, and it is difficult to meet the needs of urban development. The high-voltage cable method has many advantages such as high line operation safety, small urban space occupation, and easy operation and maintenance. It is increasingly welcomed by power supply companies. This paper introduces the suitable conditions for the trenchless channel cable laying technology, and briefly describes the construction process, general scheme, equipment selection and impact on the facilities to be crossed, and this provides theoretical guidance for engineering practice of trenchless channel cable laying.
