Key Considerations for Line Engineering—Told to You by a Power Construction Company

The power construction company recognizes that China is vast and that geological conditions vary significantly from one region to another. In some areas, the soil is soft clay; transmission line foundations constructed on such soil are referred to as soft-soil foundations. Typically, three types of foundations are used for soft-soil conditions: cast-in-place bored piles, spread footings, and mat foundations.

Backfilling Techniques for Cable Projects

Backfilling Techniques for Cable Projects

Backfilling procedures for cable works: (1) After placing warning signs on the cover plate to prevent external damage, the area around the cable shall be backfilled with compacted soil in accordance with municipal requirements. (2) The backfill material shall be compacted in layers. In general, the compaction coefficient of the backfill shall not be less than 0.94, and the backfill shall be free of stones or other hard objects.
