Description
Technical field
The utility model belongs to agricultural technology field, specifically a kind of ecological ditch with timber bank protection.
Background technology
In recent years, owing to pursuing the high yield of crops, in agricultural planting, excessive chemical fertilizer, agricultural chemicals and the herbicide etc. used causes the problem of widespread pollution from the overuse of fertilizers and pesticides in rural area to become increasingly conspicuous, one of important origin cause of formation having become China's water pollution.
Existing conventional drainage system major function is the simple requirement meeting agricultural year and draining from water yield aspect, in order to make drainage system also possess the function removing widespread pollution from the overuse of fertilizers and pesticides in rural area simultaneously, builds subtract the ecological ditch of dirty type by engineering measure and botanical system.Adopt certain engineering measure in ecological ditch, effectively firm side slope can reach the object strengthening bank protection intensity; And the water plant be planted in ecological ditch, have the function intercepting exogenous nutrition, absorb water body nitrogen phosphorus, its rhizome can also suppress the release of bed mud Middle nutrition thing, and in the plant growth later stage, convenient unified harvesting is removed simultaneously.But the bank protection structures such as the stone-laying of existing ecological ditch many employings concrete grout, wire gauze are more complicated, cost is higher and material does not meet environmental friendly principle; And use merely the ecological ditch side slope of botanical system to cave in built on the sand, easily.
Utility model content
The purpose of this utility model is for above-mentioned prior art Problems existing, provides a kind of ecological ditch with timber bank protection, the advantage that this ecological ditch has that construction cost is cheap, structure is simple, slop protection material environmental protection and being suitable for is promoted in rural area.
The technical solution of the utility model is:
With an ecological ditch for timber bank protection, comprise the substrate being positioned at bottom and two side slopes being positioned at substrate left and right sides, be provided with bed course above described substrate, each side slope is provided with number and defines rows timber and several layers of soil cover; Described timber in a row is that multiple timber is arranged in a row and is vertically placed in side slope, and timber in a row, soil cover are parallel to ecological ditch raceway groove, timber in a row, soil cover successively from the bottom to top interval be arranged in side slope; Soil cover is provided with the botanical system that can purify water; Stage casing and the end of this ecological ditch are respectively equipped with gate.
As preferably, the gradient of side slope is 1:0.7 ~ 1:1.5.
As preferably, described bed course is cobble bed course, and its thickness is 10 ~ 20cm.
As preferably, the degree of depth that each timber in described timber in a row inserts side slope is 20cm ~ 40cm; Described timber trestle column in a row is 30 ~ 40cm.
As preferably, described botanical system is wetland plant, and planting density is 15 ~ 20%.
As preferably, described botanical system is made up of submerged plant or emergent aquactic plant.
As preferably, described submerged plant selects one or several in hornwort, black algae, eel grass.
As preferably, described emergent aquactic plant selects one or several in wild rice stem, High-Pole Lamp core grass, lotus rhizome.
The utility model beneficial effect is compared with prior art:
1. the ecological ditch side slope of the utility model use timber and botanical system to carry out ecological revetment process, not only prevent ditch slope from caving in, also delay water volume flow rate in ditch by timber and botanical system, increase hydraulic detention time, be more conducive to the removal of nitrogen phosphorus in agricultural area source pollutants;
2. the ecological ditch engineering quantity of the utility model is little, with low cost, by squeezing into timber in ecological ditch side slope, playing the effect of firm side slope, also delaying water volume flow rate simultaneously, make the botanical system in side slope fully can clear up nitrogen and phosphorus pollution thing in water body, reach the object removing widespread pollution from the overuse of fertilizers and pesticides in rural area;
3. botanical system of the present utility model has selected the industrial crops being easy to safeguard, by harvesting regular every year, not only eliminates the trouble of regular maintenance, also brings certain economic benefit.
Accompanying drawing explanation
Fig. 1 is the schematic cross-sectional view of the ecological ditch of the utility model;
Fig. 2 is the top view of the ecological ditch of the utility model.
In figure: 1 is substrate; 11 is bed course; 2 is side slope; 21 is timber in a row; 22 is soil cover; 23 is botanical system; 3 is gate.
Detailed description of the invention
Below in conjunction with attached Fig. 1 and 2, the utility model is described in further detail.
With an ecological ditch for timber bank protection, comprise the substrate 1 being positioned at bottom and two side slopes 2 being positioned at substrate left and right sides, be provided with bed course 11 above described substrate 1, each side slope 2 is provided with number and defines rows timber 21 and several layers of soil cover 22; Described timber in a row 21 is arranged in a row for multiple timber and is vertically placed in side slope 2, and timber 21 in a row, soil cover 22 are parallel to ecological ditch raceway groove, timber 21 in a row, soil cover 22 successively from the bottom to top interval be arranged in side slope 2; Soil cover 22 is provided with the botanical system 23 that can purify water; The stage casing of this ecological ditch and end are respectively equipped with gate 3.
Ecological ditch cross section is by design side slope standard advanced row slope trimming, and the gradient of side slope 2 is 1:1, and bottom width is 1m, and cutting depth is 1.0m, and ecological ditch normal depth of flow is 65cm.Bed course 11 is the cobble bed course of 10cm for thickness, prevents substrate to be subject to current scour.Every side slope is provided with three and defines rows timber 21, and each timber in timber 21 in a row is through preservative treatment, and the degree of depth inserting side slope 2 is 35cm, plays and prevents slope failure and slow down the double action that current make water body be fully purified; Timber 21 trestle column in a row is 30 ~ 40cm.
Botanical system 23 is wetland plant, and planting density is 15 ~ 20%, and botanical system planting density is 1 clump/m
2; Botanical system 23 is made up of submerged plant or emergent aquactic plant; Submerged plant selects one or several in hornwort, black algae, eel grass; Emergent aquactic plant selects one or several in wild rice stem, High-Pole Lamp core grass, lotus rhizome.Gather in botanical system 23 in November, after effectively preventing it dead, residual body causes the nitrogen phosphorus substance of absorption to discharge after decomposing.Meanwhile, wild rice stem is industrial crops, also brings certain economic well-being of workers and staff after harvesting.Ecological ditch stage casing and end arrange gate, control flow rate of water flow and maintain the daily depth of water between 30 ~ 40cm.
The running of the ecological ditch of the utility model band timber bank protection: after water enters ecological ditch, when flowing through timber, flow velocity can reduce, hydraulic detention time increases, water purification plant between timber carries out Adsorption to the nitrogen and phosphorus pollutants in water body, realize the abundant purification to nitrogen phosphorus pollution of area source, the water of purification can repeated application in side farmland or open gate water flowed out from ecological ditch, utilized by downstream.
The utility model is not limited to above-mentioned embodiment, and the change that those skilled in the art make above-mentioned embodiment and change, all can not exceed the protection domain of design of the present utility model and claim.
