Sliding skid ring for pipe feedthroughs

Sliding skid ring for a pipe member, to be laid underground inside a jacket pipe, consisting of at least two segments, connected to each other by means of tightening elements, held under pretension against the pipe member in a nonpositive manner, and carry outward-pointing sliding skids, characterized in that;

• the sliding skid ring (1) is comprised of several identical segments (10);
• each segment (10) being provided on one side with a radial section in the form of one of more tabs (12) and, on the opposite side, with another radial section in the form of a closure part (17) having one or more insertion slots (18) designed to accept the tabs, the tabs (12) of an adjacent segment (10) being engaged in the slots;
• the tabs (12) have a plurality of parallel and equidistant grooves (13), which are at a slant of a few degrees to the axial direction;
• the closure part (17) has, in the engagement area of the tabs (12), an axially oriented guide grooves (20) for a tongue-like wedge (30, 40), which is inserted therein;
• the wedge (30, 40) having grooves (33, 43), which are oriented to correspond with the grooves (13) in the tabs (12) and are in engagement therewith;
• the wedge (30, 40) being driven axially into the guide grooves (20) until the two adjacent segments (10) are tightened together and the sliding skid ring (1) is thus held pressed against the pipe member.
