发明名称 Conduit spacer anchoring system
摘要 A system for anchoring the conduit spacers of a utility duct bank in a fixed position within a trench during encasement or burial of the duct bank. The conduit spacers comprise components having mating bosses by means of which they can be horizontally and vertically interlocked. A holder interfits with the horizontal or side attachment bosses and includes a vertical guide opening for receiving a length of steel reinforcing bar or other elongated member. The length of reinforcing bar is inserted through at least one, and preferably two or more aligned and driven into the earth forming the floor of the trench, and the top portion of the bar is secured as by being bent over the upper holder to prevent the duct bank from shifting or floating upwardly as when concrete is poured around it. The shape of the holders is such that a tapered notch is created between the conduit spacer and holder fitted thereto for receiving a horizontally extending reinforcing rod to provide added strength to the duct bank.
