Abstract
An elongated plastic chamber utilized for disposal of stormwater has a corrugated wall structure having successive peaks and valleys. The peaks and valleys are connected by upstream and downstream web panels. A series of apertures is disposed in the upstream web panels. The associated facing downstream web panel is smoothly integrated with the corresponding valley to form a curved surface which is concave with respect to the associated peak and serves to deflect outwardly from the chamber water emergent from the apertures. The effect of the interaction of the apertures with the curved surface is to minimize deposition of sediment within the chamber.
Claims10
In a water dispensing chamber fabricated as a plastic structure elongated upon a straight axis between inlet and exit extremities and having a wall of arch shape cross section defining an open bottom and having a multiplicity of alternating peaks and valleys running along the arch shape in planes orthogonal to said axis and interconnected by facing upstream and downstream web panels wherein said upstream web panel is closer to said inlet than the associated downstream web panel, the improvement comprising:
- a) a series of apertures disposed in said upstream web panels, and
- b) downstream web panels which are smoothly integral with each associated valley, forming a curved impingement surface which is concave with respect to the associated upstream peak, said impingement surface serving to deflect outwardly from said chamber water emergent from said associated apertures.
