An interlocking splice for prestressed concrete piles
KIE-LOCK splices are interlocking steel connectors, precast into prestressed concrete piles. When a driven section reaches its limit before the pile reaches bearing, the splice locks the next section on so driving can continue.
Where KIE-LOCK earns its place
If pile lengths are too long for casting, hauling, or driving in one piece.
Where low head-room or height restrictions require short segments.
Enables the use of smaller equipment for cheaper hauling or driving.
Where it is in the public safety interest to loft and drive shorter segments.
