Abstract:

Three selected sump grates were tested to evaluate their hydraulic and debris handling performance in a sump condition. The grates were selected based on the results of a previous study - Bicycle-safe Grate Inlets Study - Volume 1 - Hydraulic and Safety Characteristics of Selected Grate Inlets on Continuous Grades. The major objective of the initial study was to identify, develop, and analyze selected grate inlets which maximize hydraulic efficiency and bicycle safety. Six sizes of each sump grate design were tested on a 1:2 scale model representing a sump condition at the bottom of a vertical sag. The grates were tested using a longitudinal slope of 0.2 percent and roadway cross slopes of 1/48, 1/24, and 1/16 with gutter flows represented up to 30 ft^3/s (0.85 m^3/s). Numerous design curves are provided to aid the hydraulic design engineer with sump grate selection.
