Abstract

The drainage holes of a common rainwater cover in cities are relatively large, so that leaves, sand, branches, paper scraps, small stones and the like directly enter a drainage pipe, the drainage pipe is locally and even totally blocked, the water flows un-smoothly and is accumulated, and water logging is produced. By using the characteristics that substances heavier than water can be settled in the water and substances lighter than water can float on the water surface, a barrel-like object can be designed; the substances with high specific gravity are settled at the bottom of the barrel; and for reducing the floating substances to enter the drainage pipe, the drainage holes are designed to upwards incline for 45 degrees. For preventing pests such as mosquitoes, flies and the like from being grown in the rainwater held in the barrel, water seepage holes which incline for 45 degrees are designed at the bottom of the barrel.

Description

Heavy mud bucket design

Technical field

The heavy mud bucket design of the present invention relates to the urban construction field, relates in particular to drainage works.

Background technology

Rainwater lid drain hole common in the city is a rectangle, and rectangle has 20-30 mm wide.The main problem that exists is: leaf, silt, twig, paper scrap, gravelstone is first-class can get into drainage pipe from this drain hole.Though drainage pipe is provided with catch-basin at a certain distance, silt can not be deposited in the catch-basin fully yet, because the proportion of foreign material such as leaf, branch and water is suitable; Effect of settling is not good, may accumulate in the drainage pipe position, along with gathering of drainage pipe foreign material; The silt that comes subsequently will further be piled up; Because silt is more tiny, with the person's of plaing a part sealant, the intensity of foreign material adds that the compactness of silt will make the local even all obstructions of gutter; Make current freely not cause city ponding, cause waterlogging.

Summary of the invention

Part city waterlogging often since leaf, silt, branch, paper scrap, the first-class entering drainage pipe of gravelstone cause, thereby avoid or reduce their getting into drainage pipe and just can reducing the waterlogging risk.

The design scheme of the heavy mud bucket design of the present invention is: utilize the proportion can sedimentation gradually in water than the big material of water; The material that proportion is littler than water can swim in the water surface; The material that swims in the water surface is general bigger, can design an object as bucket, and heavy material is deposited in the bucket bottom; Be to reduce floating thing and get into drainage pipe, with drain hole 45 degree that are designed to be inclined upwardly.

The beneficial effect of the heavy mud bucket design of the present invention is: get into drainage pipe and avoid larger object to get into drainage pipe owing to reducing silt and floating thing, thereby alleviate the burden of drainage pipe catch-basin, the obstruction of minimizing drainage pipe reduces city waterlogging risk.

Description of drawings

Fig. 1 is a kind of heavy mud bucket design scheme.

Wherein: 1, round tank edge; 2, circular staving; 3, the aperture 8mm drain hole of downward-sloping 45 degree; 4, the be inclined upwardly aperture 8mm drain hole of 45 degree, 5, the aperture 4mm drain hole of 45 degree that are inclined upwardly, 6, the aperture 2mm drain hole, 7 of 45 degree that are inclined upwardly, 45 degree aperture 1mm infiltration hole tilts.

Specific embodiments

Heavy mud bucket is fixed on the drainage pipe under the rainwater lid, also can be designed to rectangle and pipe shape is consistent.Edge (1) through bucket is fixed on below the rainwater lid, and rainwater is through in the heavy mud bucket (2) of the entering of rainwater lid.The silt that most of proportion is bigger than water, metal, stone etc. will sink to the bucket bottom.Bucket infiltration hole, bottom (7) is smaller, is designed to aperture 1mm, and purpose is after not coming water, and the water that remains in the bucket slowly is penetrated into drainage pipe through infiltration hole (7), grows harmful organisms such as mosquito, fly thereby avoid in bucket, depositing certain water body.When the bucket middle water level arrives drain hole 6; Water will flow into drainage pipe through drain hole 6, and drain hole 6 is designed to aperture 2mm, towards 45 degree that tilt; Behind the inclination drain hole; Have only the water surface to exceed the drain hole certain altitude, water just can be got rid of, and the floating thing that can reduce like this in the water gets into drain hole (6).When rainwater is bigger, after perhaps drain hole (6) had been stopped up in sedimentation, water level rose to drain hole (5); Water is discharged through drain hole (5); Drain hole (5) design aperture 4mm improves drainage speed, and 45 degree that tilt get into drainage pipe to reduce floating thing.When rainwater is bigger, after perhaps drain hole (5) had been stopped up in sedimentation, water level rose to drain hole (4); Water is discharged through drain hole (4); Drain hole (4) design aperture 8mm further improves drainage speed, and 45 degree that tilt get into drainage pipe to reduce floating thing.When rainwater is bigger, after perhaps drain hole (4) had been stopped up in sedimentation, water level rose to drain hole (3); Water is discharged through drain hole (3), and drain hole (3) design aperture 8mm improves drainage speed; Downward-sloping 45 degree; Sedimentation will no longer be piled up but directly will be washed into drainage pipe behind this position, can not make heavy mud bucket can not draining cause waterlogging because silting stops up drain hole.

When heavy mud bucket shoal materials is few, when coming water big, all undersurface drain holes all can be participated in draining, improve drainage speed.

Heavy mud bucket should be checked in the regular hour, took out foreign material such as silt, ensured its normal function.

Claims

1. heavy mud bucket is a kind of tub, and its principal character is: at the drain hole that bucket wall and bucket end designed size differ, the aperture, lower part is little, and the aperture, top is big.

2. heavy mud bucket according to claim 1 is characterized in that: the lower part drain hole be inclined upwardly 45 the degree.

3. heavy mud bucket according to claim 1 is characterized in that: topmost the drain hole and the infiltration hole downward-sloping 45 at the bucket end are spent.
