Embodiment Construction

[0019] This embodiment is located in a modern agricultural park in Shanghai, and specifically includes the following steps:

[0020] Step 1) Carry out preliminary arrangement and remove the original concrete slope protection and floor of the farmland drainage ditches.

[0021] The preliminary finishing refers to: remove the open ditch guard and bottom plate of the traditional drainage ditch, restore the natural state of the drainage ditch, thereby open up the material and energy exchange channels between the water body in the drainage ditch and the bottom and wall of the ditch, and restore the habitat of plants and animals;

[0022] Step 2) Set up a water collection well of 1.5m x 1.0m x 0.8m (length x width x depth) at the junction of the farmland drainage outlet and the ecological drainage ditch, and set a 0.3 x 0.1m (width x depth) outlet weir at the outlet of the water collection well .

[0023] The water collection well is a sunken rectangular parallelepiped structure, w...

Abstract

The invention discloses a building method for a farmland ecological drainage ditch preventing the ditch wall soil loss. By performing preliminary processing on an original drainage ditch, a water collecting well is arranged at the joint of a farmland drainage port and the ecological drainage ditch, and after being subjected to preliminary precipitation in the water collecting well, farmland runoff enters the ecological drainage ditch through a water outflow weir; on the basis of solidifying of holes reserved in the ditch bottom of the ecological drainage ditch and ditch wall sloping treatment, the ditch wall of the ecological drainage ditch is subjected to strengthening treatment by means of porous ecological drainage ditch side plates, and purifying plants are planted in vegetation planting holes reserved in the side slope and the bottom of the ecological drainage ditch; and finally, a water baffle is arranged on a drainage port of the ecological drainage ditch, and the farmland rainfall runoff is purified by the ecological drainage ditch and then enters a river. The building method for the farmland ecological drainage ditch preventing the ditch wall soil loss has the beneficial effects of being easy, convenient and practicable, capable of preventing the ditch wall soil loss, stable in structure, good in purifying effect, good in landscape effect and the like.

Description

technical field [0001] The invention relates to a technology in the field of environmental protection, in particular to a method for constructing farmland ecological drainage ditches, which is used for the prevention and control of agricultural non-point source pollution and can prevent ditch wall soil loss. Background technique [0002] Farmland drainage ditches are water channels located on both sides of the road or in the field for farmland drainage (flood discharge). Drainage ditch is a semi-natural wetland ecosystem under the influence of human activities, which has an important impact on agricultural production and ecological environment, and is a common landscape element in agricultural areas. The irrigation and drainage function of ditches is an important guarantee for agricultural production and ecological security. With the increasingly serious water environment problems, the role of ditches in the prevention and control of water environmental pollution and the pro...
