  • Publication number: 20030163960
    Abstract: A square riser with corner threaded rods is used to repair utility standards. The riser threaded rods are bolts with washers welded to the bolt heads. The utility standard base is removed from its footing with four threaded rods, the riser slid down over the footing threaded rods and welded to them. Nuts on the footing threaded rods are used to level the riser. The riser can if desired be filled with poured concrete, to strengthen and protect it. The utility standard base is then slid down over the riser threaded rods and secured by nuts. A sleeve made of two paired half shells snugly fitting the bottom of the utility standard above the base can be welded to the utility standard. Reinforcing brackets are sometimes welded to the middles of the half shells and to the standard base. On occasion both methods of repair may be combined. It is far cheaper to repair than replace utility standards. The methods and material meet all North American standards for utility standard repair.
