S e c t i on 2 - P a ge 8 May 2013 • In addition to impr oved mixing pr operties the “posimix” device also tends to pump the plastic skin of the chemical anchor to the back of the hole which eliminates the ‘gloving’ ef fect. • All DSI conventional chemical bolts can be manufactur ed as “posimix” bolts and supplied to suit either left or right hand bolt r otation. • Recommended hole size is 31 to 38mm diameter . • Corr osion pr otection may be pr ovided by hot dip galvanizing. Posimix Resin Bolt System General Featur es • Manufactur e of the “posimix” bolt is the addition of a specially designed spring wir e attached to the up hole end of many of DSI r ock bolts. • The “posimix” bolting system was designed to assist in the installation of r ock bolts with chemical anchors in lar ger diameter holes (31-38mm) by pr oviding: • substantially enhanced mixing of the chemical anchors, • load transfer capabilities a re maximised, • the ability to be installed with a face jumbo as well as hand held machines. • The “posimix” device centralises the bolt in the hole allowing an even distribution of the chemical anchor ar ound the bolt. It also acts as an Ar chimedes scr ew pump for cing the chemical towar ds the back of the hole, assisting in mixing whilst consolidating the anchor for impr oved load transfer pr operties. www .dsiundergr ound.com
