Thanks Richard!
Do you have a sample spec. for the granite blocks?
Do you have any history and descriptions of how they perform ?
Appreciate your reply!
Thanks!
I assume we are in agreement that a drop MH system works better than velocity control rings .
If the orifice situation also works for the high flow, then this maybe the way to go!!
Many thanks !
Thanks !
The drop MH concept sounds reasonable and will be an improvement over the original 31% sloping pipe of 44' length.
However, if the total drop is only 13.6' & we are dropping 4 to 5' each MH, the pipe slope between MH's can be very mild, why "25%" pipe run?
If we connect the drop MH...
Hi All,
already seen HEC 14 but not enough info for design.
drop structure seems good, but need details on the height of drop, length of base and protection for the base slab. Apprecaite a detail if available. If multiple drops are needed, need design guide on such a structure. Total length...
Need suggestions on energy dissipator for an urban trunk line w/ limited space for downstream structures before connecting to existing 10' x 8.5' RCB at 0.08 slope w/ already 150 cfs upstream of the connection : urban trunk line Data -31% slope ( 13.6 ' drop for 44 ' length) w/ 145 cfs to 175...
