| The interception capabilities of storm water grate inlet were analyzed in this paper. The hydraulic model lot gutter flow was used to estimate the interception capability. With the consideration of width and length of road, gutter discharges were ranged of 4-15l/sec. The transverse slopes of gutter were selected 4, 7 and 10%. The longitudinal slopes were 0, 2, 5 and 7%. The four sizes of storm water grate inlet were used in this experiments ($30 imes40cm,;40 imes50cm,;40 imes100cm,;40 imes150cm$). The total number of experimental cases were 240. As the transverse slopes of gutter increased, the interception capability also increased. As the flow width in gutter and the discharge were lower, the interception efficiencies increased and the longitudinal slopes of road increased, the interception efficiencies decreased. The empirical formula with the factors of total inflow discharge, the longitudinal slope and the transverse slope of gutter were derived. These equations could be used to estimate the intercepting discharge of grate inlet. The reasonable construction space of grate inlet for the road widths, the longitudinal slopes, the transverse slopes and the grate inlet sizes were suggested. |
