Such as Authorization Notice No. is that the Chinese patent of CN 203878735U discloses a kind of unpowered from clear overflow lattice
Grating system, including for covering the grid in discharge outlet, the end face of grid offers some rows for draining
Tank, the end face entirety of grid outwards arches upward and forms cylindrical arc curve.This utility model in use, changes
Becoming rubbish to cover on grid end face in the way of the contact of face, the mode becoming point cantact or linear contact lay is blocked in the past
Cut in the cylindrical arc curve of this utility model grid, be conducive to intercepting more rubbish.But, circular arc lattice
When spacing between grizzly bar is excessive, this utility model possibly cannot realize the effect of overflow grating, if spacing is too small,
Because there is no extra cleaning equipment, it is impossible to clean thoroughly, when therefore the dirt in rainwater is more, may send out
Raw blocking.
Therefore, the science and technology research and development of this area and engineers and technicians are devoted to develop one and dam that efficiency is high, self-cleaning
Effective, design simple in construction, stabilization of equipment performance is good, installation is easy and construction costs is cheap sewerage system
Early-stage rainwater overflow grating and method.
