Description
Technical field
The utility model relates to a kind of roof drain pollutant interception and using method thereof, and particularly a kind of foldable rainwater water inlet cuts device that is dirty and that conveniently remove contamination and using method thereof.
Background technology
Inlet for stom water is the necessary channel that urban rainwater is got rid of, and is urban sewerage and drainage system " throat "; Town road storm-water drainage is to the work of urban traffic and resident and live most important, and discharge freely will directly not affect work and the daily life of people; Therefore, effective management of inlet for stom water is most important to urban drainage pipeline system; The management of current China inlet for stom water is perfect not enough, and inlet for stom water blocking situation happens occasionally, and has seriously undermined the conveyance capacity of inlet for stom water, thus causes the surface gathered water even series of problems such as urban waterlogging.
Before arriving annual rainy season, rainwater carries the solid waste such as a large amount of leaves, rubbish and silt by not only easily blocking drainage pipe after inlet for stom water, the discarded object of long-term accumulation can give out a burst of stink, have a strong impact on the normal life of resident, usually cause the complaint of resident, indivedual local particularly evident; Municipal sector will draw clearly inlet for stom water, but wastes time and energy, and draws clearly expense also cumulative year after year; Therefore, need to arrange the rubbish that pollution cutting device interception enters inlet for stom water at inlet for stom water place, and regular removing contamination to it effectively can prevent from the blocking of inlet for stom water and drainage pipe, also needs to reduce inlet for stom water management cost simultaneously; As can be seen here, roof drain pollutant interception rational in infrastructure, easy to use can greatly facilitate the management of inlet for stom water, economically feasible.
The rain perforaled strainer structure that the many employings of roof drain pollutant interception domestic are at present single, the many employing 500 × 300mm of pollution cutting device of existing town road rainwater water inlet or 750 × 500mm standard iron are combed, and it is excessive to enter sink size, dirt infilters drainage pipe and precipitates easy blocking pipe for a long time; There is deadweight more than existing pollution cutting device too large, inconvenience of removing contamination, affect the problems such as inlet for stom water conveyance capacity, the applicability seriously hindering roof drain pollutant interception with apply.
