Abstract
A construction method of an ecological riverbed is used for destructed riverbeds. The construction method includes: filling a mixed substrate layer composed of silts, construction wastes, large-particle sand grains and aggregates to the bottom layer so as to change conditions of an originally polluted riverbed; paving a soil layer mainly composed of slags, turves and soils collected around the river above the mixed substrate layer; and planting plants such as cattails and reeds on the soil layer. By the construction method, stable flora is constructed, ecology of the river is improved, and the ecological riverbed is constructed.
Description
Technical field
The invention belongs to field of environment engineering technology, be specifically related to a kind of ecological river bed methods of member such as the grains of sand, stone, peat, building waste, slag, submerged plant of utilizing.
Background technology
In recent years, national economic development is rapid, and urbanization process is more and more faster, has taken a large amount of land resources, causes arable area to reduce rapidly.In order to increase arable area, people just begin to open up wasteland some rivers and lakes soil on every side.Cause the rivers and lakes area to reduce, water and soil resources run off.On the other hand, carried out a large amount of production owing to developing the economy, produced huge industrial refuse, household garbage, these rubbish just do not enter the river through suitable processing, cause river ecosystem to be destroyed, and himself recovery capability descends.Animals and plants are owing to living environment is suffered seriously to change to become extinct in the river, and river is further rotten, fouling.In order to change this present situation, improve the living environment of river surrounding resident, improve resident's quality of life, if the original healthy ecology of restoring river system becomes a popular problem of numerous scholar's research.
Methods such as at present, China mainly adopts machinery to dredge, diversion is removed contamination are come the ecosystem of restoring river.But this method of curing the symptoms, not the disease can not thoroughly be dealt with problems, and causes bounce-back easily.How to make up the river ecosystem of a health, remain a technical barrier that does not have solution.
Summary of the invention
The object of the present invention is to provide a kind of ecological river bed method that makes up.
Technical scheme of the present invention is:
After the river course carries out the machinery dredging; Utilize some unpolluted mud, building waste, the grains of sand that particle is bigger, the crushed stone of diameter 1-4cm to be tiled in the river bed; Its proportion of composing is 2: 1: 1: 3, constitute a mixed-matrix layer, and its thickness is 5-20cm; The top of mixed-matrix layer is a soil horizon, near the unpolluted soil peat of the slag of diameter 1-6cm, diameter 1-5cm, the river under spreading successively, and its thickness is followed successively by 5-15cm, 2-10cm, 1-5cm; Edaphic top is the submerged plant crowd, chooses in cattail, reed, canna, mullet grass and the Arundo donax two or more and mixes plantation, and plant is 15-45cm at interval.
Effect of the present invention is:
What make up in this way is ecological river bed, and the current that are suitable for depth of water 40-200cm are the river comparatively slowly, and it not only can remove original pollutant in the river, can also lay a good foundation for the river ecosystem that rebuilds a health.
The specific embodiment:
At first, the river of being administered is carried out mechanical desilting, afterwards in 2: 1: 1: 3 ratio, will mix being tiled in the river bed for the crushed stone of contaminated mud, building waste, salad, diameter 1-4cm, thickness is 5cm, constitutes the mixed-matrix layer; Again above it successively the shop down thickness be respectively 10cm, 5cm, 4cm peat, slag, do not receive the nearly river soil of pollution, constitute soil horizon, 20m at interval between the soil horizon; Above edaphic, choose canna and Arundo donax is planted, 20cm at interval between the plant.After more than accomplishing, carry out the river and pour water, the speed of pouring water is wanted slowly, in order to avoid be flushed to plant, the last degree of depth of water body reaches 60cm.
Claims (3)
1. an ecological river bed construction process is characterized in that being made up of mixed-matrix layer, soil horizon, submerged plant three parts.
2. according to the said method of claim 1, it is characterized in that using some mud, building waste, the grains of sand that particle is bigger, the crushed stone of diameter 1-4cm to be tiled in the river bed, thickness 5-20cm, each material proportion is 2: 1: 1: 3.It above the mixed-matrix layer soil horizon; Choose local untainted near river soil, the slag of diameter 1-6cm, the peat of diameter 1-5cm and be tiled in the top of mixed-matrix layer; Various material thickness are followed successively by 1-5cm, 2-10cm, 5-15cm; Gross thickness 8-30cm, interval 10-30m between the soil horizon.The soil horizon top is the submerged plant part, and submerged plant is chosen two or more in cattail, reed, canna, mullet grass and the Arundo donax etc., mixes plantation.
3. according to the application of right 2 said methods, it is characterized in that this method is suitable for the middle-size and small-size comparatively slowly river of current of depth of water 40-200cm.
