Abstract

The utility model relates to a soil property side slope with multistage grass planting ditch, it is domatic including the soil property, the last horizontal interval excavation of soil property domatic has many grass planting ditches. The bottom of the grass planting ditch is of an arc structure, the width of the ditch opening is 1.0 meter, and the depth of the ditch is 0.5 meter; the distance between two adjacent grass planting ditches is 15-20 meters. And a gravel layer, geotextile, a sand layer and a planting soil layer are sequentially paved in the grass planting ditch from bottom to top. The utility model discloses set up many horizontal grass planting ditches on domatic, can directly collect the domatic water that comes of upper level during rainy to stagnate through the grass planting ditch and hold and infiltration down, both promoted domatic ecological landscape effect, increased the infiltration rate of domatic rainwater again, effectively reduced domatic runoff, alleviateed soil erosion and water loss, subducted the runoff pollutant simultaneously.

Description

Soil slope with multistage grass planting ditches

Technical Field

The utility model relates to a soil property side slope of river course dykes and dams, highway, view microtopography especially relates to a soil property side slope with multistage grass planting ditch.

Background

River dikes, highways, landscape microtopography and the like are mostly designed into soil slopes, as shown in figure 1. In order to reduce water and soil loss caused by rain erosion of a slope surface, the existing soil slope mostly adopts water intercepting and draining facilities such as a longitudinal and transverse masonry drainage ditch, an torrent groove and a water intercepting ditch which are arranged on the slope surface, generally adopts a grouted stone or concrete structure, are relatively hard and have poor ecological properties, have smooth and closed surfaces, are not beneficial to rain infiltration, and only can directly drain water from the slope surface to an adjacent branch ditch at the foot of the slope; in addition, some soil slopes have long slopes and large catchment areas, and if the drainage ditches are small in size and scale and cannot meet drainage requirements, rainwater can overflow to wash slope feet and garden roads.

Disclosure of Invention

An object of the utility model is to provide a soil property side slope with multistage grass planting ditch can effectively reduce domatic runoff, alleviates soil erosion and water loss, has subdued the runoff pollutant simultaneously.

In order to achieve the above purpose, the utility model can adopt the following technical proposal:

soil property side slope with multistage grass planting ditch, it is domatic including the soil property, the domatic last horizontal interval excavation of soil property has many grass planting ditches.

A gravel layer, geotechnical cloth, a sand layer and a planting soil layer are sequentially paved in the grass planting ditch from bottom to top.

The distance between two adjacent grass planting ditches is 15-20 meters.

The bottom of the grass planting ditch is of an arc structure, the width of the ditch opening is 1.0 meter, and the depth of the ditch is 0.5 meter.

The utility model has the advantages of set up many horizontal grass planting ditches on domatic, can directly collect the domatic water that comes of last one-level when raining to stagnate through the grass planting ditch and hold and infiltration down, both promoted domatic ecological landscape effect, increased the infiltration rate of domatic rainwater again, effectively reduced domatic runoff, alleviateed soil erosion and water loss, subducted the runoff pollutant that comes from embankment slope top road surface simultaneously.

Fig. 4 is a cross-sectional view of the grass-planting trench of fig. 2.

Detailed Description

The present invention will be described in more detail with reference to specific embodiments, which will facilitate the understanding of those skilled in the art.

It should be understood by those skilled in the art that the present embodiment is only for explaining the principle of the present invention, and is not intended to limit the scope of the present invention. Although the drawings are drawn to scale, the scaling is not constant, and those skilled in the art can adjust the drawings as needed to suit specific applications, and the adjusted technical solution will still fall within the protection scope of the present invention.

Fig. 1 shows a left side slope 101 of a landscape microtopography, a garden path 102 is paved at the bottom of the slope, and plants 103 are planted on the slope. When raining, rainwater flows down from high to low (garden way) to wash the slope surface, so that water and soil loss is caused, and when the rainwater is large, the rainwater can overflow to wash slope feet and garden way.

In order to solve the technical problem, the utility model discloses a soil property side slope with multistage grass planting ditch, as shown in fig. 2-4, including the domatic 1 of soil property, the horizontal interval excavation has many grass planting ditches 2 on domatic 1 of soil property, has laid gravel layer 2.1, geotechnological cloth 2.1, sand bed 2.3 and planting soil layer 2.4 from bottom to top in proper order in grass planting ditch 2.

The utility model discloses a grass planting ditch is domatic transversely falls into multistage domatic, and during the rainy, every grass planting ditch all can directly collect the domatic water that comes of last one-level to stagnate through the grass planting ditch and hold and infiltration down, both promoted domatic ecological landscape effect, increased the infiltration rate of domatic rainwater again, effectively reduced domatic runoff.

Because the slope is generally defined as 1: 3-1: 5, the distance between two adjacent grass planting ditches is preferably 15-20 m, and the steeper the slope is, the smaller the distance between the grass planting ditches is.

In general, the bottom of the grass planting ditch 2 can be designed into an arc structure, the width of the ditch opening is 1.0 meter, the depth of the ditch is 0.5 meter, and small trees can be planted in the ditch.

Claims

1. The utility model provides a soil property side slope with multistage grass planting ditch, includes that the soil property is domatic, its characterized in that: a plurality of grass planting ditches are transversely excavated on the soil slope surface at intervals, and the grass planting ditches transversely divide the slope surface into a multi-stage slope surface; the bottom of the grass planting ditch is of an arc structure, the width of the ditch opening is 1.0 meter, and the depth of the ditch is 0.5 meter; the distance between two adjacent grass planting ditches is 15-20 meters.

2. The soil slope with multi-stage grass planting furrows of claim 1, wherein: and a gravel layer, geotextile, a sand layer and a planting soil layer are sequentially paved in the grass planting ditch from bottom to top.
