Description
A Splitset is a tube used for temporary or permanent stabilisation of a rockmass and comprises an open steel tube and faceplate. The high strength steel tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a welded ring flange to hold the bearing plate. The tube is driven into a slightly smaller diameter hole, using the same standard percussion drill used to drill the hole. The slot narrows during insertion and then tries to return to its original shape causing radial pressure to be exerted against the rock over its full contact length.
The units can be Zinc diffused for corrosion protection.
