The specific embodiment
Road roadside rainwater lid dust cover, rainwater lid itself has difference with other rainwater drowning, and rainwater lid 1 has drain hole 2, and drain hole 2 is identical with other rainwater lids: be strip or circular or other forms.The rainwater lid is in a relatively low lowered zones 5, the rainwater lid is desilting nest 41 time, storm sewer is bypass storm sewer 3, be on the wall of desilting nest 4 the gutter road junction to be arranged, stop up for avoiding the gutter road junction, bypass storm sewer 3 is from the direction of current, i.e. interior to outer direction from desilting nest 4, bypass storm sewer 3 downward-sloping 30-45 degree.
A dust cover 6 that mates with the rainwater lid, the upper surface of dust cover 6 is stained with spherical air bag 7, soffit is stained with bar-shaped air bag 8, the diameter of bar-shaped air bag 8 is less than the size of the drain hole 2 of rainwater lid 1, bar-shaped air bag 8 puts in drain hole 2, the upper surface of dust cover 6 soffits contact rainwater lid 1, the drain hole 2 of sealing rainwater lid 1.
