How to model a pipe stubbing into an RCB?

Hi,

I am using StormCAD CONNECT Edition to model the storm sewer we are designing for a highway project. We have one scenario on the project where we are running a trunk line that is a 5' x 3' RCB under a roadway that has a curb inlet on it capturing water in the sump. There is a 24" pipe coming out of this inlet and we are interested in connecting the water from the pipe to the water from the trunk line. However, we do not want to use a junction box to make the connection since they will be able to just stub the 24" pipe into the side of the RCB. How would I lay out the model in StormCAD to account for such a situation without the use of a manhole/junction box node?

  • Hello John, 

    In StormCAD you can model the 5' x 3' RCB, as a concrete box conduit connecting to the catch basins, as you mentioned it has a curb inlet on it capturing water.

    For the connection part of box and circular pipe, do you mean that you don't want any structure at the connection point of 24" pipe and 5' x 3' RCB trunk line? In that case you can use transition node in StormCAD which will be connection point between these two conduits. Layout >Transition element, or when you select conduit to layout, right click in drawing area and select transition as the connection node. 

    If this does not then please elaborate your query.
