Abstract
The utility model discloses a sand base water filtering ditch which comprises a water filtering ditch body (1) and a cover plate (2) covered on the ditch body (1). The cover plate (2) and the ditch body (1) both are in water permeable structure. The cover plate (2) and the ditch body (1) respectively comprise a water permeable surface layer (4) and a water permeable base layer (5). The water permeable surface layer (4) and the water permeable base layer (5) are tightly combined into a whole. An arc-shaped groove (3) is arranged on the upper surface of the cover plate (2). The cover plate is in the water permeable structure, and cost is low. Moreover, aperture of water permeable holes of the water permeable layer is much smaller than grain materials in water, not only can large and small solid materials be prevented from entering a water draining ditch, but also sewage exhausted into the ditch can be primarily filtered. Therefore, blocking of the ditch body is avoided, and storage water in the ditch body can automatically ooze into soil to supplement underground water in returning mode.
Description
Technical field
The utility model relates to the gutter that draining is used, and relates in particular to the sand base water-filtering ditch that uses in a kind of road drainage system.
Background technology
Road surface, soil ponding when avoiding raining, affect traffic safety, road both sides or easy ponding place generally are provided with the gutter, existing discharge section slightly is the U font, end face covers the ditch lid with hole or slit, utilizes the ditch lid accepts water, because existing U-shaped gutter furrow bank mostly is closed construction, make the ponding that enters the ditch body enter the ground water drainage pipe network by coupled pipeline or passage, increased the weight of the burden of municipal sewage treatment.
For this reason, Chinese patent literature CN201128851Y discloses a kind of side permeable drainage ditch, and this side permeable drainage ditch comprises: two furrow banks and the bottom of trench between two furrow banks, two furrow banks and bottom of trench consist of the permeable gutter of a side.The gutter of above-mentioned prior art can a side carry out permeable, in utilizing its drainage procedure, can be under the prerequisite without manual intervention, by seeping water in the other soil of permeable side direction road.But in the practice of construction process, bear the road surface of larger load for needs, its bed course, layer of concrete and roadbed partly mostly are impermeable material and make to prevent sinking of pavement of road, because the one side that above-mentioned gutter and road join is that impermeable material is made, like this by the ponding that oozes under the road surface, need to lay separately pipeline ponding is discharged to soil or the city planting ductwork in roadside, increased the cost of road construction and the processing cost of Sewage Plant.Existing gutter adopts the rainwater bamboo comb to collect surface gathered water more in addition, and the rainwater bamboo comb can only still have many little solid matter and elongate rod to fall into drainage body thick foul gear outside ditch lid, causes the obstruction in gutter.
The utility model content
Technical problem to be solved in the utility model is to need to lay separately pipeline in the prior art to collect ponding under the road surface, thereby cause the cost of road construction and the high problem of processing cost of Sewage Plant, and existing drain cover, can't stop that little solid matter falls into drainage body, thus the problem that causes the gutter to stop up.
For addressing the above problem, the technical scheme that the utility model is taked is:

In the above-mentioned sand base water-filtering ditch, the aggregate of described porous base course is comprised of in pervious concrete, silica sand, rice stone or the haydite one or several.
Compared with prior art, sand base water-filtering ditch of the present utility model has following advantage:
(1) sand base water-filtering ditch of the present utility model, described cover plate is permeable structure, the particle of its permeable aperture in the water, can stop that not only large and small solid matter enters the gutter, can also tentatively filter the sewage that enters described ditch body, thereby avoid the obstruction of ditch body, and the permeable structure of described sand base water-filtering ditch ditch body can make ponding under the road surface to ditch body inner penetration, thereby reduced the laying of road surface lower pipeline, and then reduced the cost of road construction.
(2) sand base water-filtering ditch of the present utility model, the effect of filtration is not only played on the permeable top layer that consists of described cover plate, also can be as required upper shades of colour, itself and road surface on every side are complementary, thus more attractive in appearance.
(3) sand base water-filtering ditch of the present utility model, the upper surface of described cover plate is provided with the groove of circular arc, not only increased the infiltration area, in fact also can be used as the open drain uses, when rainfall is larger, collect and the discharging surface gathered water, the side that described cover plate and curb are joined is higher than the side away from curb, guarantees that the ponding in the groove can not be back on the road surface.
(4) sand base water-filtering ditch of the present utility model, the permeable structure of described sand base water-filtering ditch ditch body can make ponding under the road surface to ditch body inner penetration, thereby have reduced the laying of road surface lower pipeline, and then have reduced the cost of road construction.
(5) sand base water-filtering ditch of the present utility model, water in the described ditch body can ooze back in the soil automatically, in order to conserve soil, plant and the microorganism growth such as auxiliary flowers, plants and trees, rainwater covering quality of groundwater after sand base water-filtering ditch filters is good, not the polluted underground water source.
(6) sand base water-filtering ditch of the present utility model, the water in the described ditch body can ooze back in the soil automatically, has reduced the displacement in the sewage network, and then has reduced the processing cost of Sewage Plant.
