Abstract

The utility model provides a design of a mud settling box. A water inlet of a city rain pipeline is a rectangle with the width of 25-30 mm. As larger sundries, such as branches, leaves, small rocks and the like, can directly enter into a drainage pipeline, the sundries stack at a position of the drainage pipeline so that followed silt stack may completely block the drainage pipeline. As substances including slit and the like with the specific gravity which is greater than that of water are easier to precipitate, the substances are located at the bottom of a water flow and move forwards under a force of the water flow. If some rectangular boxes with the width of 25-30 mm are arranged at the positions through which the water flows, the substances including silt and the like with the specific gravity which is greater than that of the water may precipitate in the rectangular boxes, so as to reduce the silt entering into the drainage pipeline and decrease the load of a catch basin of the drainage pipeline.

Description

Heavy mud box design

Technical field

The heavy mud box design of the utility model relates to the urban construction field, relates in particular to drainage works.

Background technology

The urban rainwater pipeline water inlet often is the rectangle of 25-30 mm, since more roomy, drainage pipe also can directly be got into as bigger foreign material such as branch, leaf, small stones; Though 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 foreign material such as leaf, branch and water is suitable, effect of settling is not good; Be deposited in certain position of drainage pipe easily; Come silt to continue to pile up at this subsequently, the intensity of bigger material adds the compactness of silt, just possibly block this drainage pipe fully.

Summary of the invention

The utility model main purpose is to reduce silt to get into drainage pipe.

The utility model to the technical scheme that silt gets into drainage pipe is: because the big material of silt geometric ratio anharmonic ratio water precipitates easily; Be in the bottom of current; Be that the strength of current is impelled and moved forward; If some low-lying places are set in the position of current warp, the material that then silt geometric ratio anharmonic ratio water is big just might be deposited in this low-lying place, thereby reduces the silt that gets into drainage pipe.

The beneficial effect of the utility model: owing to get into the silt minimizing of drainage pipe, thus alleviate the burden of drainage pipe catch-basin, reduce the obstruction risk of drainage pipe, reduce soil erosion and purified water quality with part.

Description of drawings

Fig. 1 is heavy mud box sketch map.

Wherein 1, the 10mm circular hole, 2, the 3mm circular hole.

Specific embodiments

Design a kind of rectangular box of not with closure, because blow-by, tread in injuredly for fear of pedestrian's pin,, advise box width 25-30mm so width is unsuitable excessive.Bigger if desired rectangular box then must add the seal cover of band raster, and grid size is good with 25-30mm.It is lower slightly that urban road generally is designed to the edge, and heavy mud box mainly is placed on the road edge that rainwater is flowed through, length 150-200mm, and the road edge that has is equipped with the bar shaped cement block, and this situation length can be consistent with the cement block width.2 10mm circular holes (1) are used to hang up hook and take out heavy mud box, and 3mm circular hole (2) is positioned at the bottom, and effect is after rain stops, and the water that is trapped in box are penetrated into underground, keep the silt of box more dried, avoid growing insects such as mosquito, fly.

Claims

1. heavy mud box is a rectangular box, it is characterized in that: width 25-30mm, length 150-200mm; 2 10mm circular holes; The 3mm circular hole is positioned at the bottom.
