anchored as required. Vibration isolated equipment shall be specially designed to meet <br /> these same requirements. <br /> B. PIPING <br /> All piping, raceways, accessories, and appurtenances furnished with equipment shall <br /> be anchored to resist a lateral seismic force of 60% of its operating weight without <br /> excessive deflection. This force shall be considered acting at the center of gravity of the <br /> piece under consideration. <br /> Piping with flexible connections and/or expansion joints shall be anchored such that the <br /> intended uses of these joints are maintained in the piping system. <br /> SECTION 11100 — SLUICE GATES <br /> PART 1—GENERAL <br /> 1.01 DESCRIPTION <br /> A. Scope: <br /> This section specifies sluice gates of cast iron construction for control of water flow. — <br /> B. Type: <br /> Sluice gates shall be of cast iron construction with full metal wedges, flat frames, and <br /> square wall thimbles with flush-bottom compressible resilient seal attached with <br /> stainless steel bar and stainless steel fasteners. <br /> C. Operating Requirements: <br /> Gate Size Bottom F60 <br /> si n Head, feet O erator <br /> Number inches Seatin tin Unseatin Type <br /> 2 36 x 36 Flush 30 Manual <br /> D. Component Sizing: <br /> 1. Operating forces used for determining the strength of gate components <br /> comprising of yokes, frames, discs, stems, disc nut pockets, and other <br /> load-bearing members shall be based on the sum of the guide friction <br /> force (computed using an opening breakaway friction factor of 0.70) and <br /> the weight of disc and stem. <br /> 2. When the gate is in motion, the operating forces shall be based on the — <br /> sum of the frictional force (using a guide friction factor of 0.35) and the <br /> weight of disc and stem. <br /> 1.02 SUBMITTALS <br /> Division III-119 NEI Phase II Water and Sewer — <br /> July 2007 CIP Nos. 7468, 7589, 7590 <br />
