Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see figure 1 , providing a percolation type directional drainage ecological ditch, comprising a gravel drainage layer 7, a permeable geotextile 6, a fine sand filter layer 5, a percolating nutrient planting soil layer 4, an organic covering layer 3, plants 1 and Ground cover slope 2. The crushed stone drainage layer, the fine sand filter layer, the percolating nutrient planting soil layer, and the organic covering layer are adjacently arranged from bottom to top. The permeable geotextile is arranged on the u...

Abstract

The invention discloses a percolating directional drainage ecological ditch which comprises a gravel drainage layer, a fine sand filter layer, a layer with percolating nutritional planting soil, an organic mulch layer, plants, and ground cover slopes, wherein the gravel drainage layer, the fine sand filter layer, the layer with the percolating nutritional planting soil and the organic mulch layerare adjacently arranged from bottom to top; the plants are planted on the surface layer of the percolating directional drainage ecological ditch; the ground cover slopes are arranged on both sides ofthe surface layer of the organic mulch layer; and the ground cover slopes and the organic mulch layer are connected with a field around. By adopting the mode, by adopting the percolating directional drainage ecological ditch disclosed by the invention, runoff rainwater on the ground can be drained directionally through the ecological ditch and fed into sponge city treatment facilities in a rain spell, overland flows can be reduced, the rainwater can be purified, stored and percolated along with the ditch, and plants growing in the ditch have functions of softening and beautifying the field.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a percolation type directional drainage and drainage ecological ditch. Background technique [0002] With the continuous advancement of the urbanization process, most of the urban roads and squares are paved with hard pavements. In case of rainy season, it is easy to cause water accumulation and overflow on the ground. At present, most of the rainwater runoff from roads or squares is directly discharged through the municipal rainwater system, which is not conducive to the control of the runoff of the sponge city. Sponge city facilities need to collect water, and it is necessary to build a ditch system with directional drainage function, and then effectively connect the sponge city facilities in order to maximize their effectiveness. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a percolation type directional...
