Structure and use of remotely releasable pile connectors

摘要

A rigid connection for joining together two successive sections of a string of piling or the like includes a tubular box member, a pin member having a portion which projects into the box member, a locking member operable to releasably hold the pin and box members against separation, and a retaining element for holding the locking member in its active locking position. The locking member may take the form of a split ring having an interruption within which the retaining element is receivable to hold the locking member in an expanded locking condition. The locking member is preferably initially actuated to its locking condition by fluid pressure actuated means.
