In order to achieve the purpose, the technical scheme adopted by the farmland ecological water-retaining ridge is as follows:

the utility model provides a farmland ecology water-retaining ridge, includes plain soil foundation, plain soil foundation's top both sides are provided with the brick wall that permeates water that builds by laying bricks or stones with permeating water, and brick wall is next to the water drainage canal to one side, and brick wall is next to the farmland to the opposite side, and brick wall inside wall that permeates water of both sides and plain soil foundation's top surface have formed the cavity, and the impermeable geotechnique's cloth has been laid to the bottom surface of cavity, and impermeable geotechnique's cloth's top surface is provided with the filtration adsorbed layer of arranging in the cavity inside, and the top of cavity is provided with the apron that shelters from the filtration adsorbed layer.

Preferably, the filtering and adsorbing layer comprises a first filling layer and a second filling layer, wherein the first filling layer is positioned on one side of a farmland, the filler of the first filling layer is porous pumice, the second filling layer is positioned on one side of a drainage channel, and the filler of the second filling layer is gravel.

Preferably, the cover plate is provided with a toughened glass observation window.

Preferably, the height of the water permeable brick wall is 300mm, the specification of the water permeable brick is 200mm x 100mm x 55mm, and the porosity of the water permeable brick is 30%.

Preferably, the plain soil foundation is 100mm higher than the farmland ground, the plain soil foundation is penetrated with a drain pipe communicated with the farmland side and the drainage canal side, one end of the drain pipe is provided with a plug, and the plug is a cork.

Compared with the prior art, the utility model has the following advantages:

1. when the farmland is in water withdrawal, the farmland enters the cavity through the water permeable brick wall next to one side of the farmland, is purified by the filtering adsorption layer, and is discharged to the drainage channel through the water permeable brick wall next to one side of the drainage channel, so that the pollution of the farmland in water withdrawal with high pollution load to water is effectively relieved.

2. The cover plate is provided with a toughened glass observation window, so that the water flow state and the microbial film generation condition inside the cavity can be observed conveniently.

Drawings

FIG. 1 is a front view of an ecological water-retaining ridge of a farmland of the present utility model;

FIG. 2 is a cross-sectional view of the ecological water-retaining ridge of farmland of the present utility model.

The water-permeable brick wall comprises a 1 element soil foundation, a 2 drain pipe, a 21 plug, a 3 permeable brick wall, 4 impermeable geotechnical cloth, a 5 filtering adsorption layer, a 51 first filling layer, a 52 second filling layer, a 6 cover plate and a 7 toughened glass observation window.

Detailed Description

The present utility model is further illustrated in the accompanying drawings and detailed description which are to be understood as being merely illustrative of the utility model and not limiting of its scope, since various equivalent modifications to the utility model will fall within the scope of the appended claims to the skilled person after reading the utility model.

As shown in figures 1-2, the ecological water-retaining farmland ridge comprises a plain soil foundation 1, wherein the plain soil foundation is tamped by undisturbed soil to reach a watertight state, the plain soil foundation is 100mm higher than the ground of the farmland, the plain soil foundation penetrates through a drain pipe 2 communicated with the side of the farmland and the side of a drainage canal, a plug 21 is arranged at the end part of the drain pipe on the side of the farmland, the plug is a cork plug, when the farmland needs to be drained, farmland water can be directly drained into the drainage canal, water-permeable brick walls 3 are built on two sides of the top of the plain soil foundation by using water-permeable bricks, the water-permeable brick walls are 300mm in height, the specification of the water-permeable bricks is 200mm x 100mm 55mm, the porosity of the water-permeable bricks is 30%, the water-permeable brick walls on one side are next to the drainage canal, the water-permeable brick walls on the other side are next to the farmland, the inner side walls of the water-permeable brick walls on the two sides and the top surface of the plain soil foundation form a cavity, the bottom surface of cavity lays prevention of seepage geotechnique cloth 4, prevention of seepage geotechnique cloth's top surface sets up the filtration adsorbed layer 5 of arranging in the cavity inside, it includes first filling layer 51 and second filling layer 52 to filter the adsorbed layer, first filling layer is in farmland one side, the filler of first filling layer is porous pumice, the particle diameter of porous pumice is 3-5mm, the second filling layer is in water drainage canal one side, the filler of second filling layer is the gravel, the particle diameter of gravel is 6-9mm, the apron 6 of shielding filtration adsorbed layer is arranged at the top of cavity, disconnect long-shaped apron in the suitable position, the position is used for installing toughened glass observation window 7 in the position of leaving for observing the inside rivers state of cavity and the microbial film condition of growing.

The concrete working process and principle of the farmland ecological water-retaining ridge are as follows: under normal conditions, the drain pipe is plugged by the cork, the water level in the farmland rises, when the water level reaches the top surface of the soil foundation and above, water on one side of the farmland enters the cavity through the permeable brick wall on the side, and after being adsorbed, filtered and degraded by microorganisms by the first packing layer and the second packing layer, purified water enters the drainage channel through the permeable brick wall on one side of the drainage channel. The utility model purifies water at one side of farmland and then discharges the purified water into the drainage canal, thereby effectively relieving the pollution of high pollution load farmland water return to water body, and being beneficial to the construction of a field ecological system.
