CHARGE ASSEMBLY FOR A PIPE-COUPLING CUTTING DEVICE

摘要

A charge assembly (12) for use in a cutter for splitting couplings used in joining together lengths of buried pipe (36) is provided that allows several explosive charge segments to be used instead of a single explosive charge. The smaller explosive charge segments utilize less explosive material which complies with applicable shipping regulations. The abutment members may be provided with biasing means (136) for engaging the longitudinally aligned charge segments and urging the charge segments into the abutting relationship. Further, a charge segment retainer (116), which includes a pair of longitudinally extending rails (121), may be provided and located within the interior of the housing. The charge retainer engages the charge segments for lateral retention of the charge segments within the interior of the charge housing.
