This manhole will be buried 60 feet below grade at the bottom of the landfill. Considering the allowable deflection of the structure under loading from landfill compactor, we determine the structure should have a minimum wall thickness of 6 inch. Concrete is out of question because this...

I am designing something very similar using 36 inch nomial ID HDPE pipe as a riser for the manhole buried at the base of the landfill 60 feet below grade. I am not sure about the function of your shear ring construction. However, we are using a different type of design to support the...
Can anyone recommend me a plastic design/manufacturer who can construct a seven feet OD HDPE manhole with a wall thickness of at least 6 inches? I am getting answers from few suppliers that it is impossible with existing technology!
Have you ever considered using analytical solution to obtain your answer or alternatively construct a simple two dimenional model to study the drawdown and zone of influence?
