ENERGY DISSIPATOR AND ASSOCIATED SYSTEM FOR USE IN SUMPED FLOW-THROUGH MANHOLES

摘要

An energy dissipator for use in a sumped manhole includes a sheet member. The sheet member defines a downstream surface, an upstream surface opposite the downstream surface, and opposing side edges each extending between the downstream surface and the upstream surface. The sheet member includes a plurality of apertures. Each of the plurality of apertures extends through both the downstream surface and the upstream surface. The sheet member extends in an arcuate manner between the opposing side edges. The dissipator is configured to intercept fluid flow within the manhole to decrease energy and control flow dynamics within the manhole.

1. A drain system comprising:
a sumped manhole including an inlet opening for receiving an inlet pipe and an outlet opening for receiving an outlet pipe; an energy dissipator comprising:
a sheet member defining a downstream surface, an upstream surface opposite the downstream surface, and opposing side edges each extending between the downstream surface and the upstream surface, wherein:
the sheet member includes a plurality of apertures,each of the plurality of apertures extends through both the downstream surface and the upstream surface,each of the opposing side edges is coupled to the sumped manhole on opposing sides of the inlet opening such that the sheet member bows away from the inlet opening,the sheet member extends in an arcuate manner between the opposing side edges, andthe dissipator is configured to intercept a fluid flow within the manhole to decrease energy and control flow dynamics within the manhole.
