Ecological ditch with remediation function and laying method thereof

Abstract

The invention provides an ecological ditch with a remediation function. The ecological ditch comprises impermeable layers sequentially laid from bottom to top to prevent water flow permeation, a planting layer for aquatic plant to grow and an aquatic plant blanket layer with aquatic plant planted thereon, wherein the planting layer is provided with a trapezoidal surface; and the aquatic plant blanket layer is fixedly laid on the trapezoidal surface of the planting layer. In the invention, an impermeable film and the planting layer are directly laid in the ditch, and high diversity of species is maintained; the aquatic plant blanket layer is laid at the upper part of the planting layer, and the water body is deeply remediated; and the construction way of the ditch replaces traditional reinforced concrete structure. A laying method of the ditch comprises the following steps: (i) ditch flattening; (ii) laying of the impermeable layers; (iii) laying of the ecological planting layer; (iv) laying of the aquatic plant blanket layer; (v) planting of the plant; and (vi) mounting of a water retaining device. In the invention, the laid aquatic plant blanket has good tensile strength; and due to the laid nonwoven and plastic net, the blanket forming effect of the aquatic plant blanket is good.

Description

technical field [0001] The invention relates to the technical field of water and soil engineering, in particular to an ecological ditch with restoration function and a laying method of the ditch. Background technique [0002] With the continuous progress of the society, in order to meet the requirements of the national sponge city construction plan, there are more and more urban buildings. The biggest problem brought about by urban planning is the problem of the urban drainage system. The urban drainage system is to treat and remove urban sewage and rainwater. The engineering facility system is an important part of urban public facilities. Since urban planning needs to consider factors such as beautification and environmental protection, building ditches in cities is an indispensable method. [0003] Ditches are public facilities built by people for urban water transfer and distribution. Due to the imperfect planning of urban buildings, when building ditches, the existing ri...
