If the water quantity entering the water storage cavity is larger and is larger than the outflow speed of the negative pressure water channel, in order to avoid that the water is not discharged in time, a flood discharge water channel is arranged for discharging more water, and water logging is avoided.
Preferably, the caliber of the flood discharge water channel is larger than that of the negative pressure water channel. So as to provide a more fluid drainage channel.
Preferably, the water inlet end of the negative pressure water channel is positioned at the bottom of the water storage cavity, and the middle part of the negative pressure water channel is bent upwards. So as to form a siphon waterway.
Preferably, the water storage cavity is divided into an upper cavity and a lower cavity by the filter screen, the water inlet end of the negative pressure water channel is positioned in the cavity, and the water inlet end of the flood discharge water channel and the water outlet end of the water inlet channel are positioned in the upper cavity.
The water entering into the water inlet channel can be filtered through the filter screen, the large-scale impurities are prevented from entering into the negative pressure pipeline to form blockage, and when excessive water enters into the water storage cavity, the excessive water can be discharged through the flood discharge channel.
Preferably, the filter screen is detachably adapted to the water storage cavity. So as to remove sludge or smaller impurities from the lower chamber.
The beneficial effects of the utility model are as follows:
this scheme is through setting up the flood discharge water course, can enter into the water storage chamber at having excessive water, can't in time discharge when going, discharges it through the flood discharge water course, avoids because unable in time discharge ponding, forms the waterlogging on the road surface.
Drawings
