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

A kind of heavy mud bucket

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

Common rainwater cover drain hole is rectangle in the city, and rectangle has 20-30 mm wide.The main problem that exists is: leaf, silt, twig, paper scrap, gravelstone is first-class can enter drainage pipe from this drain hole.Although drainage pipe is provided with catch-basin at a certain distance, but silt can not be deposited in the catch-basin fully yet, because the proportion of the foreign material such as leaf, branch and water is suitable, effect of settling is not good, may be gathered 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, makes current freely not cause city ponding, causes waterlogging.

Summary of the invention

The urban waterlogging enters that drainage pipe causes because leaf, silt, branch, paper scrap, gravelstone are first-class often, thereby avoids or reduce them entering 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 gradually sedimentation in water than the large material of water, the material that proportion is less than water can swim in the water surface, the material that swims in the water surface is generally larger, can design an object as bucket, heavy material is deposited in bottom of the barrel, enter drainage pipe for reducing floating thing, 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: enter drainage pipe and avoid larger object to enter drainage pipe owing to reducing silt and floating thing, thereby alleviate the burden of drainage pipe catch-basin, reduce the obstruction of drainage pipe, reduce 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, be inclined upwardly 45 the degree aperture 8mm drain holes, 5, the be inclined upwardly aperture 4mm drain holes of 45 degree, 6, the aperture 2mm drain holes, 7 of 45 degree that are inclined upwardly, 45 degree aperture 1mm water seepage holes tilt.

Specific embodiments

Heavy mud bucket is fixed on the drainage pipe under the rainwater cover, also can be designed to rectangle and pipe shape is consistent.Edge (1) by bucket is fixed on below the rainwater cover, and rainwater is through in the heavy mud bucket (2) of entering of rainwater cover.The silt that most of proportion is larger than water, metal, stone etc. will sink to bottom of the barrel.Bottom of the barrel water seepage hole (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 by water seepage hole (7), grows the harmful organisms such as mosquito, fly thereby avoid depositing certain water body in bucket.When the bucket middle water level arrives drain hole 6, water will flow into drainage pipe by drain hole 6, drain hole 6 is designed to aperture 2mm, towards 45 degree that tilt, behind the inclination drain hole, only have 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 enters drain hole (6).When rainwater is larger, after perhaps drain hole (6) had been stopped up in sedimentation, water level rose to drain hole (5), water is discharged by drain hole (5), drain hole (5) design aperture 4mm improves drainage speed, and inclination 45 is spent to reduce floating thing and entered drainage pipe.When rainwater is larger, after perhaps drain hole (5) had been stopped up in sedimentation, water level rose to drain hole (4), water is discharged by drain hole (4), drain hole (4) design aperture 8mm further improves drainage speed, and inclination 45 is spent to reduce floating thing and entered drainage pipe.When rainwater larger, after perhaps drain hole (4) has been stopped up in sedimentation, water level rises to drain hole (3), water is discharged by 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 large, all undersurface drain holes all can participate in draining, improve drainage speed.

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

Claims

1. a heavy mud bucket is a kind of tub, and its principal character is: heavy mud bucket is fixed on below the rainwater cover by round tank edge (1), and rainwater enters in the circular staving (2) through rainwater cover; At bucket wall and the bucket end drain hole not of uniform size is arranged, lower part aperture is little, upper part aperture is large, the bucket wall has four circle drain holes, be respectively from top to bottom from the bucket outside bucket the aperture 8mm drain hole (3) of downward-sloping 45 degree of direction, from the bucket to bucket outside direction be inclined upwardly 45 degree aperture 8mm drain holes (4), from the bucket to bucket outside direction be inclined upwardly 45 degree aperture 4mm drain holes (5), from the bucket to bucket outside the be inclined upwardly aperture 2mm drain holes (6) of 45 degree of direction, the bucket end, be that inclination 45 spends aperture 1mm water seepage holes (7).
