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.
In the invention, rainwater is subjected to primary filtration by the rainwater grate and secondary filtration by the grid basket dirt-intercepting groove and then is subjected to tertiary filtration in the rainwater settling area, sand and stone particles are settled in the rainwater settling area and then pass through the overflow filtration area, and clear water is collected by the overflow filtration head, passes through the overflow vertical pipe and then is discharged to the rainwater inspection well through the discharge pipeline. The environment-friendly gutter inlet with three-stage filtration has the following advantages: 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.
