Detailed description of the invention
See Fig. 1, this device, by erecting stream well (2) and upper reaches well (11) two parts forms, passes through bottom connecting hole (12) between perpendicular stream well (2) and upper reaches well (11) connected.Perpendicular stream well (2) dark 3.0 meters, length and width are 1.0 meters; Dark 2.0 meters of upper reaches well (11), length and width are 1.0 meters; Upper reaches well (11) elevation of top is lower than (2) 0.5 meters, perpendicular stream well.Perpendicular stream well (2) sieves (3) by rain perforaled strainer (1), energy dissipating, sand hopper (4) forms, and wherein, dark 0.5 meter of sand hopper (4), four inclination angles, limit are 60 °, and sand position inductor (9) is installed at sand hopper (4) top, and submersible sewage pump (10) is installed in bottom.Upper reaches well (11) is made up of clear water zone (8), filtration beds (7), water distributing area (6), two-phase laminated flow district (5) four part, and upper reaches well (11) bottom is the italic structure at 30 °, inclination angle, is connected bottom italic with connecting hole (12) bottom; Dark 0.5 meter of clear water zone (8); Dark 0.5 meter of filtration beds (7), is made up of the limestone of particle diameter 30mm; The dark 10cm in water distributing area (6); Dark 0.5 meter of two-phase laminated flow district (5), is made up of the stainless steel set square of 5 inclination layer 45 °.
When rainy day, rainfall started, road storm runoff is dammed after thick object by rain perforaled strainer (1) and directly enters in described device, drop in energy dissipating sieve (3) through perpendicular stream well (2), due to the elastic reaction of energy dissipating sieve (3), cut down storm runoff kinetic energy, simultaneously, the particle that density is larger can sieve (3) surperficial landing to sand hopper (4) along energy dissipating, the sand grains that the comparatively large and grain diameter of density is less than 1mm then can penetrate energy dissipating sieve (3) and directly enter sand hopper (4) under the effect of inertia force.Storm runoff after usefulness enters upper reaches well (11) through connecting hole (12), first through two-phase laminated flow district (5), initial gross separation bulky grain silt particle, enters filtration beds (7) after water distributing area (6) uniform water distribution, and after filtering, water outlet enters drainage pipe through clear water zone (8).After running a period of time, interface, sand position in sand hopper (4) raises gradually, when sand position inductor (9) senses that interface, sand position arrives setting absolute altitude, start submersible sewage pump (10), the silt particle dammed is discharged outside well, centralized collection process, simultaneously, discharge in sand hopper (4) dam silt particle time, the clear water in clear water zone (8) will carry out backwash automatically to filtration beds (7).
