OBERMEYER HYDRO, Inc. Ideas that Hold Water

Installation of OBERMEYER spillway gates is quick and easy. For systems up to approximately 4 Meters high, the air bladders are secured to the spillway with a row of anchor bolts. For system heights above 4 meters, an embedded clamp is used to secure the gate system to the spillway. The anchor bolts may be embedded in a new spillway or may be secured in holes drilled into an existing spillway. The air supply lines which connect to each individual air bladder can be embedded or grouted into a saw slot in the spillway. Surface mounted air supply lines may also be used. A typical installation sequence is as follows:

• Place anchor bolts
• Install air supply lines
• Install abutment plates, if used
• Place air bladders over anchor bolts
• Secure air bladders to spillway with clamp bars
• Connect air supply lines to underside of air bladders
• Attach steel gate panels to each air bladder
• Attach interpanel seals
• Attach restraining straps if used
• Attach nappe breakers
• Adjust and grout abutment plates or install J seals
• Install compressor, drier and controls
• Start up system
