Example four:
the invention provides a method for dredging an urban rainwater port and discarding initial rainwater, which can adopt two modes:
firstly, an inner container 10 is arranged in the rainwater port, and a gap 9 is formed between the inner container 10 and the rainwater port. At the initial stage of rainfall, the runoff just formed, the velocity of flow is less, and the initial stage rainwater passes through the outer clearance of inner bag 10 and flows into lower floor's storage space, and along with the rainfall constantly increases, the runoff increases, and velocity of flow grow, and the later stage rainwater rushes into inner bag 10, and the rainwater pipeline 2 is gone into through inner bag 10 to the continuous increase of inner bag 10 interior rainwater.
Secondly, install inner bag 10 in the inlet for rainwater, install the starting and stopping mechanism in the inner bag 10, the starting and stopping mechanism structure is the same with embodiment one, and the repeated description is omitted here.
In the early stage of rainfall, rainwater flows along the road, and the initial rainwater enters the lower storage space through the gap (the size of the gap can be adjusted according to actual conditions) outside the inner container 10. Along with the continuous increase of rainfall, the rainwater that directly falls into in inner bag 10 and the rainwater that pours into from the inlet for stom water all around constantly increase, rainwater water level risees in inner bag 10, and floater 5 floats on the top, drives water blocking sheet 4 through transfer line 12 and inserts draw-in groove 11, closes the clearance 9 outside inner bag 10, makes the later stage rainwater all get into inner bag 10 and discharge rainwater pipeline 2.
When the rainfall stops, along with the natural evaporation, the rainwater in the inner container 10 is gradually reduced to be dry, the floating ball 5 descends, and the gap 9 outside the inner container 10 is opened; waiting for the next time the rainfall comes, and circulating the process.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
