Stormwater containment assembly and associated end section

Abstract

An end section or cap for a stormwater containment assembly includes a substantially half-dome-shaped body member and a connector disposed on the body member along a periphery or perimeter thereof, for coupling the body member to a stormwater chamber wall. The body member has a smooth convex outer surface with an absence of reinforcement ribs and also has a smooth concave inner surface with an absence of reinforcement ribs.

1 . An end section for a stormwater containment assembly, comprising:
 a substantially half-dome-shaped body member having a smooth convex outer surface with an absence of reinforcement structures thereon and further having a smooth concave inner surface with an absence of reinforcement structures thereon; and   a connector disposed on said body member along a periphery or perimeter thereof, for coupling said body member to a stormwater chamber wall.   
     
     
         2 . The end section defined in  claim 1  wherein said connector is an elongate corrugation integral with said body member along said periphery or perimeter thereof. 
     
     
         3 . The end section defined in  claim 2  wherein said corrugation is dimensioned to fit over a terminal lip or rib of said chamber wall. 
     
     
         4 . The end section defined in  claim 3  wherein said corrugation cooperates with said lip or rib to loosely couple said body member to said chamber wall so as to allow for slippage between said corrugation and said lip or rib in a direction radial with respect to said chamber wall and said body member and transverse to said corrugation and said lip or rib. 
     
     
         5 . The end section defined in  claim 4  wherein said corrugation defines a longitudinally arcuate cross-sectionally tapered channel receiving said lip or rib. 
     
     
         6 . The end section defined in  claim 1  wherein said body member has a substantially half-dome shape with a pair of arcuate edges, said connector being disposed along one of said edges. 
     
     
         7 . An end section for a stormwater containment assembly, comprising:
 a substantially half-dome-shaped body member having a smooth convex outer surface with an absence of outwardly projecting reinforcement ribs thereon and further having a smooth concave inner surface with an absence of inwardly projecting reinforcement ribs thereon; and   an elongate longitudinally arcuate corrugation integral with said body member along an edge or perimeter thereof.   
     
     
         8 . The end section defined in  claim 7  wherein said corrugation is integral with said body member along said edge or perimeter. 
     
     
         9 . The end section defined in  claim 8  wherein said corrugation is dimensioned to fit over a terminal lip or rib of a main chamber wall. 
     
     
         10 . The end section defined in  claim 9  wherein said corrugation cooperates with said lip or rib to loosely couple said body member to said chamber wall so as to allow for slippage between said corrugation and said lip or rib in a direction radial with respect to said chamber wall and said body member and transverse to said corrugation and said lip or rib. 
     
     
         11 . The end section defined in  claim 10  wherein said corrugation defines a longitudinally arcuate cross-sectionally tapered channel receiving said lip or rib. 
     
     
         12 . The end section defined in  claim 7  wherein said body member has a pair of arcuate edges, said corrugation being disposed along one of said edges. 
     
     
         13 . A stormwater containment assembly, comprising:
 a chamber member having an arched or vaulted wall; and   an end section including a substantially half-dome-shaped body member having a smooth convex outer surface with an absence of reinforcement structures thereon and further having a smooth concave inner surface with an absence of reinforcement structures thereon; and   a connector disposed on said body member along a periphery or perimeter thereof, for coupling said body member to said arched or vaulted wall.   
     
     
         14 . The stormwater containment assembly defined in  claim 13  wherein said connector is an elongate corrugation integral with said body member along said periphery or perimeter thereof. 
     
     
         15 . The stormwater containment assembly defined in  claim 14  wherein said corrugation is dimensioned to fit over a terminal lip or rib of said arched or vaulted wall. 
     
     
         16 . The stormwater containment assembly defined in  claim 15  wherein said corrugation cooperates with said lip or rib to loosely couple said body member to said arched or vaulted wall so as to allow for slippage between said corrugation and said lip or rib in a direction radial with respect to said arched or vaulted wall and said body member and transverse to said corrugation and said lip or rib. 
     
     
         17 . The stormwater containment assembly defined in  claim 16  wherein said corrugation defines a longitudinally arcuate cross-sectionally tapered channel receiving said lip or rib. 
     
     
         18 . The stormwater containment assembly defined in  claim 13  wherein said body member has a half dome shape with a pair of arcuate edges, said connector being disposed along one of said edges.
