Specific embodiment
To make the utility model aim, advantage definitely, below in conjunction with specific implementation of the attached drawing to the utility model
Mode is described in detail.
As shown in the figure, a kind of runoff measuring device for the sponge city implementation result for being used to assess roof greening, feature
It is that the device includes
Cistern, the cistern are set to below 1 water outlet of rain leader downspout；
Pressure sensor 5, the pressure sensor 5 are set to columns base；
Siphon pipe 2, the siphon pipe 2 are set in cistern, and bottom of pond is fixed in one end；
