Abstract

In cities, an outlet of a common rainwater cover is larger, and a large quantity of leaves, twigs, small stones and paper scraps, a large amount of sludge and the like enter a water drainage pipeline to make one part or all parts of the water drainage pipeline plugged, so water logging occurs. In the design for the sludge deposition nest, rainwater enters the water drainage pipeline through the sludge deposition nest instead of entering the water drainage pipeline directly after the sludge deposition nest deposits partial substances heavier than water and filters other impurities. In the design, a water inlet hole with the aperture of 2 millimeters, a water drainage hole which is inclined downwards 45 degrees and has the aperture of 3 millimeters, a water drainage hole which is inclined upwards 45 degrees and has the aperture of 2 millimeters, and a water seepage hole which is inclined 45 degrees and has the aperture of 1 millimeter.

Description

A kind of heavy mud nest

Technical field

The heavy mud nest design of the present invention relates to urban construction field, particularly drainage works.

Background technology

Common rainwater cover drain hole is rectangle in the city, and rectangle has 20-30mm 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 accumulate in a certain position of drainage pipe, 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, make the local even all obstructions of gutter, make current freely not cause city ponding, cause waterlogging.。

Summary of the invention

Heavy mud nest design causes waterlogging mainly for drainage pipe stops up easily.

The design scheme that the heavy mud nest of the present invention is designed to tackle obstruction is: rainwater does not directly enter drainage pipe, but after through a heavy mud nest part silt and other foreign material being filtered, enters drainage pipe again.

A kind of heavy mud nest comprises inlet opening, drain hole, water seepage hole, it is characterized in that: aperture, inlet opening 2mm, pitch of holes 4mm; Many row's drain holes are arranged at heavy mud nest inwall bottom, aperture 2mm, in the heavy mud nest outside heavy mud nest direction, be inclined upwardly and 45 spend; 1-2 row is arranged at heavy mud nest inwall top, aperture 3mm, in the heavy mud nest outside heavy mud nest direction, downward-sloping 45 spend; Water seepage hole is arranged at heavy mud nest bottom, aperture 1mm, downward-sloping 45 degree.

The beneficial effect of the heavy mud nest design of the present invention is: because large foreign material and part silt precipitated or be trapped in the heavy mud nest, thereby alleviate the burden of drainage pipe catch-basin, reduce drainage pipe and stop up, thereby reduce the risk of the waterlogging that causes because of obstruction.

Description of drawings

Fig. 1 is heavy mud nest sectional drawing.

Wherein 1,2mm inlet opening, aperture, 2, aperture 3mm drain hole, downward-sloping 45 degree 3, aperture 2mm drain hole, 45 degree that are inclined upwardly, 4, the heavy total drainage channel of mud nest, 5, mud-sinking area, 6, stop up line, 7, aperture 1mm water seepage hole, 45 degree tilt.

Specific embodiments

The 2mm inlet opening, aperture (1) of heavy mud nest is designed to aperture 2mm, pitch of holes 4mm.Drain hole is designed to 2 classes: lower part designs many rounds footpath 2mm drain hole, 45 degree (3) that are inclined upwardly, and near top design 1-2 round footpath 3mm drain hole, downward-sloping 45 degree (2), the number of drain hole is according to the area definition of heavy mud nest draining face.

Because aperture, 2mm inlet opening, aperture (1) is little, can stop comparison bigger material (such as leaf, branch, stone etc.) to enter heavy mud nest, enter that the proportion material heavier than water will be deposited in bottom the mud-sinking area (5) gradually in the heavy mud nest, rainwater is by aperture 2mm drain hole, 45 degree (3) drain holes that are inclined upwardly enter into drainage pipe, enter that the proportion material lighter than water will swim in the water surface in the heavy mud nest, enter the heavy total drainage channel (4) of mud nest for reducing floating substance, with drain hole be designed to be inclined upwardly 45 the degree, make outfall be lower than the water surface.When having reached, deposit stops up line (6), aperture 2mm drain hole, 45 drain holes of spending (3) that are inclined upwardly will be closed, this moment should sediment cleaning, if have little time cleaning, aperture 3mm drain hole then, the drain hole of downward-sloping 45 degree (2) will work, and the drain hole aperture is large, increase on the one hand drainage speed, on the other hand, since downward-sloping 45 degree drainings, thus stop up never, if deposit arrives aperture 3mm drain hole, the drain hole position of downward-sloping 45 degree (2), to no longer further deposit foreign material this moment, but directly wash away from drain hole, for avoiding this situation, should must check before periodic cleaning heavy the mud nest, particularly flood season.

Aperture 1mm water seepage hole is arranged at heavy mud nest bottom, and 45 degree (7) that tilt are designed to the 1mm aperture, and it is underground that 45 degree that tilt, Main Function are that the moisture that promotes to remain in heavy mud nest is penetrated into from this hole lentamente, avoids growing the insect of mosquito, fly and so on.

Claims

1. a heavy mud nest comprises inlet opening, drain hole, water seepage hole, it is characterized in that: aperture, inlet opening 2mm, pitch of holes 4mm; Heavy mud nest inwall lower part has many row's drain holes, aperture 2mm, in the heavy mud nest outside heavy mud nest direction, be inclined upwardly and 45 spend; 1-2 row is arranged at heavy mud nest inwall top, aperture 3mm, in the heavy mud nest outside heavy mud nest direction, downward-sloping 45 spend; Water seepage hole is arranged at heavy mud nest bottom, aperture 1mm, downward-sloping 45 degree.
