INSTALLATION, OPERATION AND MAINTENANCE MANUAL
MODEL
RB
WEIR GATES
INSTALLATION: CONCRETE WALL MOUNTED
Required Materials:
Orbinox RB Weir Gates are installed by means of Anchor Bolts. Depending on the size and working
conditions they shall be either of the mechanical or chemical type. Note that as standard, anchor
bolts and construction sealant are not supplied with the weir gate.
In order to get the expected performance of the anchor bolts, the minimum concrete strength shall
be 3,000 PSI (20.7 MPa).
In order to avoid leakage between the concrete wall and the frame, construction sealant shall be
used. (Sikabond Construction Sealant or equivalent, 200ml per meter of opening perimeter).
The following table gives a general description of the required anchor bolt types for the different gate
sizes and pressure conditions. For detailed information about the type, size and quantity of the re-
quired anchor bolts, or any other specific installation notes or materials, please refer to the notes on
the „General Arrangement Drawing‟.
