Abstract

The utility model discloses an environment-friendly type gully filtering funnel, which is on the lower portion of a rain grate of a gully, wherein the shape of an upper port of the funnel is adapted with the shape of the rain grate, the cross section is small on the lower portion and big on the upper portion, the funnel bottom of the filtering funnel is sealed, exterior margins which are extended outwards are arranged on the upper end of the surrounding side wall of the filtering funnel, a longitudinal water filtering hole is arranged on the surrounding side wall, the bottom end of the water filtering hole has certain height to the funnel bottom, which enables the bottom of the filtering funnel to have certain storage volume, and the width of the water filtering hole is increased from the bottom to the top gradually. Rainwater enters the filtering funnel and then enters the gully through the water filtering hole, contaminants in the water with bigger width than the water filtering hole are intercepted in the filtering funnel, simultaneously, and heavier solid contaminants in the water deposit on the funnel bottom 3 of the filtering funnel. The filtering funnel of the utility model can intercept 10% to 20% contaminants in the ground stream flows, smooth collection and discharge of the rainwater are also guaranteed, and the filtering funnel has prominent environmental ecological benefits and economic social benefits.

Description

Environment protection gully filter cone
One, technical field
The utility model relates to the pan of crossing of tackling pollutant in a kind of ground rainwater mouth, and belongs to hydraulic engineering and field of environment engineering.
Two, background technology
Inlet for stom water is the inlet that ground rainwater enters the rainwater pipeline.The inlet for stom water that China is traditional no matter be single grate or two grate, all is that ground rainwater is directly entered the downstream storm sewer.Have only the rain grate above the inlet for stom water can tackle bigger pollutant such as leaf, polybag, not to the control techniques of rainwater.Studies show that, the concentration of urban road runoff pollution thing SS, organic matter and heavy metal is basic identical with undressed city domestic sewage on the order of magnitude, and some pavement runoff is concentration of suspension even be far longer than municipal sewage concentration in the early-stage rainwater runoff especially.These pollutants finally enter city river after traditional inlet for stom water enters storm sewer, cause the river course water environment pollution, are pollution of area source more serious in the city, and its influence to surface water body is very serious.The inlet for stom water of Germany all has a Hanging Basket below the rain grate, its side-wall hole can further be tackled the pollutant of reduced size.But the rainfall of Germany is relatively more even, raininess is little, and the flow of inlet for stom water is also less, and it is circular that its inlet for stom water mostly is.The city rainfall of China is more concentrated, and raininess is bigger, and roads rain inlet mostly is rectangle.Therefore, under the prerequisite that ensures the rainwater conveyance capacity, descend to install a rectangle that matches at the rain double-edged fine-toothed comb of inlet for stom water and cross pan, can tackle floating thing and suspension in some rainfall runofves effectively, help improving the water quality of storm sewer.
Three, summary of the invention
The utility model is according to the years of researches result of the test, propose a kind of can effectively tackle the floating thing that enters inlet for stom water, greater particle size suspension, and can ensure the environment protection gully filter cone of conveyance capacity.
The technical solution of the utility model is, a kind of environment protection gully filter cone is provided, and describedly crosses the rain grate bottom that pan is positioned at inlet for stom water, and the shape of the shape that it is suitable for reading and rain grate adapts, and little going up greatly under the cross section; Seal at the bottom of crossing the bucket of pan; The upper end of sidewall all around of crossing pan has outwardly directed outer rim, and sidewall is provided with treatment hole longitudinally all around, and there is certain altitude the bottom of treatment hole at the bottom of described bucket, made the bottom of pan that certain storage volume be arranged; The width of described treatment hole increases from top to bottom gradually.
Further, cross pan described cross section be shaped as rectangle.
Further, the spacing of described treatment hole increases from top to bottom gradually.
This technical scheme both had been suitable for the ground rainwater mouth of sub-district, also was suitable for the inlet for stom water of urban road.Can tackle 10%~20% pollutant, effectively reduce the rainwater pollution of area source and enter downstream river course.
Further, the maximum filtering ability of this roof drain can satisfy the flow that becomes a mandarin of 50 years one chances rainfall at 15~20L/s, thereby does not influence the original conveyance capacity of inlet for stom water down.
The utility model has changed the way of the in line rainwater of traditional inlet for stom water, propose the novel form of structure of crossing pan and mounting method, both tackled a part of pollutant in the surface runoff, guarantee the smooth collection and the discharging of rainwater again, had significant environmental ecological benefit and economic and social benefits.
Four, description of drawings
Fig. 1 is the generalized section of environment-friendly type inlet for stom water.
Fig. 2 was the floor map of pan.
Fig. 3 was the generalized section of pan.
Among the figure, 1 was pan, and 2 is the rain grate of inlet for stom water, and 3 was the outer rim of pan, 4 treatment holes, and 5 are the bucket end.
Five, the specific embodiment
When the utility model is specifically implemented, comprise structure design and operational management two parts content.
Described structure design is the prerequisite that ensured pan interception road runoff pollutant and smooth and easy drainage rainwater.The contour structures of dmp filter bucket seems simply, is similar to refuse container or supermarket shopping basket, but its thin portion structure differs widely, thus have adapt to the inlet for stom water size, effectively tackle pollutant, ensure the unobstructed effect of draining.As shown in Figure 1, pan 1 excessively of the present utility model is positioned at rain grate 2 bottoms of inlet for stom water, and undersized suitable for reading is in the rain grate.The structure of crossing pan 1 as shown in Figure 2, the shape of shape that it is suitable for reading and rain grate adapts, and is generally rectangle, and under the cross section little big so that be fit into smoothly.The upper end of sidewall all around of crossing pan has the outer rim 3 of stretching out, and pan can be placed on the angle steel of reserving in the rain grate 2, and rainwater was flowed in the pan 1 swimmingly.Cross at the bottom of the bucket of pan 5 for sealing, sidewall is provided with treatment hole 4 around crossing pan, there is certain altitude the bottom of treatment hole 4 apart from the bucket end 5, makes the bottom of pan that certain storage volume is arranged like this, and the solid pollutant of being convenient in the rainfall runoff was deposited in the bottom space of pan.The width of treatment hole 4 increases from top to bottom gradually, and its spacing also increases from top to bottom gradually, so that ensure its intensity and discharge capacity.Rainwater entered inlet for stom water inside by treatment hole 4 after entering pan, and the pollutant greater than filter bores 4 width in the water will be intercepted in the pan.Simultaneously, some the heavier solid pollutants in the water deposited at the bottom of the bucket of pan 3.When coming discharge greater than than the overflow capability of the treatment hole 4 of bottom the time, the water level of crossing in the pan will go up, and satisfy up to overflow capability and come discharge.The rainwater of overflow enters inlet for stom water inside, enters the downstream line system then.
The pan of crossing of the present utility model both can be by metal manufacturings such as cast irons, also can be by the nonmetals manufacturing, as plastics, resin or composite material etc.
Described operational management is mainly desilting work.The pollutant of crossing in the pan should be cleared up once by every rain later.
