Furthermore, the connection mode between the overflow filter head and the overflow vertical pipe adopts threads, hot melting or socket joint.
Further, a drain pipe at the bottom of the gully is connected to the storm water manhole.
The bottom rainwater sedimentation zone can be used for settling and collecting particles and suspended matters in rainwater. The sedimentation zone can be modified according to the requirements, and the sedimentation effect can be increased if the sedimentation zone is set to be V-shaped.
The utility model discloses in, the rainwater is through rainwater grate one-level filtering, and the bars basket cuts dirty groove second grade filtration back, at rainwater sedimentation district tertiary filtration, and the grit granule is through the overflow filtering area after rainwater sedimentation district deposits, collects the clear water by the overflow filter head after the overflow riser, discharges the rainwater inspection shaft through the delivery pipeline. Tertiary filterable environmental protection inlet for stom water have following advantage: the rainwater inlet overflow filtering device has the advantages of being simple in structural design, easy to manufacture and maintain, low in cost, easy to popularize and apply and the like.
