Bury Depth Considerations for Manholes
March 7, 2023 @ 10:15 am - 11:15 am CST
Speaker: Riley Dvorak, P.E. – Rinker Materials
Presentation Description
We are fairly comfortable with installing RCP over 30′ deep with proper design considerations – but what about the manholes the pipes connect to? This course will discuss important considerations to take into account when designing deep (round) precast structures, including: soil forces on manhole walls, buoyant forces, and structural considerations for base slabs.
This course will look at important design considerations for deep-bury round precast structures. Topics to be addressed include:
– Horizontal soil forces on manhole wall
– Basic buoyant forces and effect of water table
– Soil weight
– Skin friction
– Bearing stress considerations
– Swelling soils
– Hydrostatic forces
– Live load considerations
– Flexural design of base slab
