Abstract
De-trenching apparatus (100) for extracting a buried line, such as a cable or pipeline, is disclosed. The de-trenching apparatus comprises a channel (112) configured to receive a buried line to be extracted, the channel comprising a first flared opening (114) at a front end of the de-trenching apparatus and a second flared opening (115) at the rear end of the de-trenching apparatus, the first and second flared openings each having a curved surface (111) configured to support the line during extraction, and material removal means for removing material from around the buried line ahead of the de-trenching apparatus.
Claims17
De-trenching apparatus and a buried cable or pipeline having a minimum bend radius, the de-trenching apparatus being configured to extract the buried cable or pipeline, the apparatus comprising:
- a channel configured to receive the buried cable or pipeline to be extracted, the channel comprising a first flared opening at a front end of the de-trenching apparatus and a second flared opening at the rear end of the de-trenching apparatus, the first and second flared openings each having an internal curved surface configured to support the cable or pipeline during extraction, wherein the internal curved surface of the first and/or the second flared openings have a radius of curvature greater than or equal to the minimum bend radius of the cable or pipeline to be extracted;
- and
- material removal means for removing material from around the buried line ahead of the de-trenching apparatus.
