Abstract

The drainage aperture of a rainwater cover common in cities is large, leaves, silt, twigs, paper scraps, stones and the like enter a drainage pipeline to cause that local even all parts of the drainage pipeline are blocked completely to cause waterlogging. A mud collection cylinder is designed as follows: rainwater indirectly enters the drainage pipeline and is used for filtering partial silt and other impurities, and then enters the drainage pipeline. The aperture of a water inlet (2) of the mud collection cylinder is designed to be 2mm, drainage holes are designed into two classes, i.e., a drainage hole (27) with the aperture of 2mm, a drainage hole (26) with the aperture of 4mm, a drainage hole (25) with the aperture of 8mm, with an upward angle of 45DEG in the incline direction, are formed at the lower part; and a drainage hole (24) with the aperture of 8mm, with a downward angle of 45 DEG in the incline direction, are arranged close to the top.

Description

Heavy mud tube design

Technical field

The heavy mud tube 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 20-30mm 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, can assemble 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; Make the local even all obstructions of gutter, make current freely not cause city ponding, cause waterlogging.

Summary of the invention

Heavy mud tube design is primarily aimed at the drainage pipe easy blocking and causes waterlogging.

The present invention stops up design scheme for reply: rainwater does not directly get into drainage pipe, but after through a heavy mud tube part silt and other foreign material being filtered, gets into drainage pipe again.

Beneficial effect of the present invention: because big foreign material have precipitated with part silt or be trapped in the heavy mud tube, thereby alleviate the burden of drainage pipe catch-basin, will significantly reduce the obstruction of drainage pipe, thus the waterlogging that minimizing causes because of obstruction.

Fig. 3 is heavy mud tube drain hole design.

Wherein 1, the rainwater lid, 2, aperture 2mm drain hole, 21, heavy mud tube urceolus, 22, sedimentation basin; 23, gutter, 24, aperture 8mm drain hole, downward-sloping 45 degree; 25, aperture 8mm drain hole, 45 degree that are inclined upwardly, 26, aperture 4mm drain hole; 45 degree that are inclined upwardly, 27, aperture 2mm drain hole, 45 degree are inclined upwardly.

Specific embodiments

The inlet opening (2) of heavy mud tube is designed to aperture 2mm; Drain hole is designed to 2 types: the drain hole (27) of lower part design aperture 2mm, the drain hole (26) of aperture 4mm, the drain hole (25) of aperture 8mm; Incline direction is 46 degree upwards; Near the drain hole (24) of top design aperture 8mm, downward 45 degree of incline direction.The number of drain hole is confirmed according to the area of the draining face of heavy mud tube.

Because aperture, inlet opening (2) is little; Can stop comparison bigger material (first-class) to get into heavy mud tube like leaf, twig, gravelstone; The proportion material heavier than water will be deposited in the bottom gradually in the heavy mud tube of entering, and rainwater is discharged into drainage pipe through the drain hole (27) in 2mm aperture.When deposit has stopped up sealing drain hole (27), perhaps come water yield ambassador water level to reach drain hole (26) position, then drain hole (26) will work, and drain hole (26) aperture design is 4mm, improves draining and hastens.When deposit has stopped up sealing drain hole (26), perhaps come the water yield big, water level reaches drain hole (25) position, and then drain hole (25) will work, and drain hole (25) aperture design is 8mm, further improves draining and hastens.When deposit has stopped up sealing drain hole (25), maybe ought come water yield ambassador water level to reach drain hole (24) position, then drain hole (24) will work, and drain hole (24) aperture design is 8mm, further improves draining and hastens.

Get into that the proportion material lighter than water will swim in the water surface in the heavy mud tube, get into drainage pipe,, make outfall be lower than the water surface, get into drainage pipe thereby reduce floating thing with drain hole (27) (26) (25) 45 degree that are designed to be inclined upwardly for avoiding floating substance.

Drain hole (24) aperture design is 8mm, is designed to downward 45 degree and can avoids drain hole (24) blocked, because downward-sloping 45 degree drainings; So stop up never, if deposit arrives the position of drain hole (24), will no longer further deposit foreign material this moment; But directly wash away from drain hole (24); For avoiding this situation, should must check once before periodic cleaning heavy the mud tube, particularly flood season.

Claims

1. heavy mud tube by special rain cover, the drain hole of particular design, cylinder of gutter overcoat constitute, it is characterized in that: the rain lid has only the edge that drain hole is arranged, and is fed directly in the heavy mud tube, it is central that drainage pipe is positioned at heavy mud tube.

2. according to the said heavy mud tube of claim 1, it is characterized in that: the draining tube wall is designed with the drain hole in 2mm, 4mm, 8mm, 8mm aperture.

3. according to the said heavy mud tube of claim 2, it is characterized in that: the drain hole in 2mm, 4mm, 8mm aperture, incline direction be 45 degree upwards; The drain hole in other one group of 8mm aperture, downward 45 degree of incline direction.
