Backfilling material and method of preparation thereof

摘要

A backfilling material and method of preparation for use with buried electrical cables. The material comprises a mixture of soil and wax in a proportion which achieves relatively low thermal resistivity to dissipate heat from the buried cable. In one embodiment the material is formed by mixing melted wax with soil. In another embodiment the material is formed by mixing soil with an emulsion of wax dispersed in an emulsifier. In another embodiment the material is formed by mixing soil with wax powdered to small particles. The mixture of soil and powdered wax is backfilled about the cable, heat from which causes self-curing as the wax melts in situ.
