[0019] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0020] like Figures 1 to 3As shown, an ecological drainage ditch wall comprises a normal water level ditch body 1 and slopes 2 symmetrically arranged on both sides of the normal water level ditch body 1, the slope ratio of the slope 2 is 1:1~1:1.5, the slope 2 can be used for drainage during the flood season, the top of the slope 2 is provided with a hollow brick layer 3 paved with hollow slabs, the hollow brick layer 3 is 30-60cm wide and 3-5cm thick, the normal water level ditch body 1 comprises a ditch bottom and vertically arranged side walls on both sides of the ditch bottom, the normal water level ditch body 1 is arranged in a U shape, the ditch bottom is arranged with a hard concrete layer 101 and a soft natural mud bottom layer 102 at intervals, and the side walls are connected to the slope 2 to form a step 201.

[0021] In this scheme, the constant water level ditch body 1 is provided so that the constant water level ditch body 1 has both anti-scouring and ecological conservation functions. The side wall height is the constant water level height, which is set to 20-40 cm high according to the actual drainage situation. The side wall includes a mortar stone layer and a 5 cm thick C20 concrete layer located above the mortar stone layer, so as to improve the anti-scouring ability and interception and drainage ability in the interception and drainage area with large runoff and strong scouring; the symmetrically arranged slope 2 can participate in flood season drainage and improve the flood season drainage capacity; the side wall and the slope 2 are connected to form a step 201. The step 201 is used to accumulate fallen concrete ecological substrate debris, grass seeds and dead branches and leaves, naturally forming a small microenvironment for earthworms, ants and other animals to live; secondly, it is convenient for pedestrians to cross the ditch, meeting the normal crossing of the ditch by young people or the crossing of the ditch by middle-aged and elderly people without weight; thirdly, the drainage ditch is not restricted by facilities during the later dredging and maintenance, and is easy to use when any ditch section is blocked or needs maintenance.

[0022] In this scheme, the slope is composed of a base layer, a surface layer and plants planted on a compacted soil layer. The base layer and the surface layer have a number of pores. The base layer and the surface layer can adopt a porous ecological concrete structure containing organic matter, soil, and a binder (cement). This porous ecological concrete has the advantages of high strength, good stability, and high porosity. It can provide water and nutrients for plant growth, allowing it to take root and sprout quickly, providing the necessary environment for plant roots, allowing plants to take root in the bottom soil, which is conducive to the production of continuous grass roots, forming a natural filter, and playing a protective role. At the same time, the concrete effectively protects the slope with its porous structure.

[0023] In one embodiment of the present invention, a water retaining ridge 103 is provided on the hard concrete layer 101 . The water retaining ridge 103 is located on the hard concrete layer 101 and close to the soft natural mud layer 102 in the opposite direction of the water flow direction.

[0024] In one embodiment of the utility model, a plurality of grooves 202 with a width of 3-5 cm are arranged side by side on the slope 2 along the direction of water flow, and the spacing between two adjacent grooves 202 is 50-80 cm, so as to facilitate the regional planting of green plants on the slope 2, and facilitate water diversion and drainage during the flood season, and facilitate debris such as gravel to slide along the grooves 202 into the ditch body 1 at a normal water level, which is beneficial to improving the stability of the ecological drainage system.
