616.01 This work consists of the construction of invert siphons per these specifications and in
conformity with the lines, grades and details shown on the plans or established. MATERIALS
616.02 Concrete Pipe. Concrete pipe shall conform to the requirements of subsection 706.02
except that pipe and gaskets shall be of a type that will ensure a watertight structure. Joints shall be self -centering. Gaskets shall meet the requirements of subsection 705.03.
616.03 Trash Guards. Steel shall conform to the requirements of subsection 712.06 and to the
details shown on the plans. Trash guards shall be given one shop coat of primer and two field coats of aluminum paint in conformity with Section 509.
616.04 Drain Valves and Valve Boxes. Drain valves shall be gate type with flanged iron body,
brass trim and brass fittings. Size will be as designated on the plans. Valve boxes shall be the adjustable cast iron type with a 5 1/2-inch minimum inside diameter. Drain valves and valve boxes shall be approved before use.
616.05 Drainpipe . Pipe for the drain shall conform to Section 605. Concrete shall conform to
Section 601 and reinforcing steel to Section 602. The pipe attached to the siphon and leading to the drain valve may be non -perforated corrugated steel pipe conforming to AASHTO M 36 or of standard galvanized pipe conforming to the requirements of ASTM A53 (Schedule 40). This pipe, when attached to steel siphon pipe, shall be bituminous dipped along with the siphon pipe. Flanges for attaching the drain valve may be galvanized or asphalt dipped. Any damaged spelter shall be repaired per subsection 707.09 both inside and outside the pipe. CONSTRUCTION REQUIREMENTS
616.06 Siphon pipe including drains shall be installed per the requirements of Section 603.
Siphons shall show no leakage when filled with water and allowed to stand full for 24 hours. This test shall be performed before backfilling. METHOD OF MEASUREMENT
616.07 Siphon pipe, of the designated type, will not be measured but will be the net length of
pipe called for on the plans, except when field changes are ordered or when there are errors on the plans. In case of exceptions, the quantity to be measured shall be t he actual net length of conduit measured along the bottom centerline of the installed pipe. Trash guards, drain valves and valve boxes will be measured by the number installed and accepted. Drainpipe will be measured and paid for per Section 605. Concre te will be measured and paid for per Section 601. Reinforcing steel will be measured and paid for per Section 602. Structure excavation and structure backfill will be measured and paid for per Section 206. Drain valves shall include the pipe for connecting the valve to the siphon, together with all necessary fittings and gaskets used.
