Abstract
The invention relates to a method for using cheap material to design biological river bed in small-scale river in country, wherein said biological river bed is formed by surface wetland and submergent plant, while its has high purify ability and sewage control ability.
Description
One, technical field
The invention belongs to the resource-environment projects technical field, relate to a kind of method of utilizing local material to carry out ecological river bed construction.
Two, background technology
Because China has a large population and a few land, the land reclamation index is constantly soaring; The soil erosion that its direct result of bringing is the farmland is very serious, causes the river to silt up because of sedimentation.Simultaneously, owing to a large amount of inputs from farmland and domestic sewage in rural areas by using, river ecosystem collapse, fishes and shrimps disappearance.The river has lost its purifying contaminated not to the utmost, cuts down the function of pollutant, even becomes sewage routeway and influence the view in plain river network area, utilizes river to carry out field irrigation and laundry also becomes a kind of extravagant hope.
In order to change the non-Health Situation in the current many rivers of China, rebuild and its ecosystem vigor of recovery, numerous rivers is become cut down the green channel that pollutes, become a urgent technical problem.
At present, China mainly adopts the method for machinery dredging, dredging+bionic plant river dredging+stone to rebuild and recovers river ecosystem.No matter which kind of method all will not recovered its ecosystem vigor, improve its clean dirty, pollution control ability as core; Thereby the river ecosystem of its recovery or reconstruction does not have vigor, more lacks continuable oneself and keeps ability.How to rebuild or recover to have the river ecosystem of biologos, remain a technical barrier that does not have solution.
Three, summary of the invention
The objective of the invention is:
Utilize cheap material, design a kind of ecological river bed building method that is applicable to middle-size and small-size river, rural area.This is ecological river bed mainly is made of jointly surface stream wetland and submerged plant.It had both had higher clean dirt, pollution control ability, did not influence it again and crossed water efficient; For reconstruction and the river ecosystem that recovery has vitality provide technological means.
The solution of the present invention is:
The present invention program is based upon after the training of river channel.
In riverbed through dredging, at first lay one deck composite interstitial substance bed course, 3 centimetres of thickness are that 1-2 centimetres rubble, building waste and the clay particle that diameter is 1-2 centimetres are formed by 6:2:2 by diameter; To delay and to stop the secondary pollution of riverbed bed mud.
On the matrix bed course,, make up 20 meters long surface stream wetland every 30 meters; Its vertical stratification is divided into 3 layers.Be respectively from bottom to top: slag layer, 10 centimetres of thickness are made up of the slag granules of 3-5 centimetres of diameters; Peat horizon, 5 centimetres of thickness are made up of the peat particle of 2-3 centimetres of diameters; And soil horizon, 2 centimetres of thickness are by unpolluted soil constitution; See Fig. 1 and Fig. 2.
Plant planting submerged plant on stream wetland surface, surface, constitute the river aquatic vegetation.Its density is that eel grass, water caltrop are 10 clumps/square metre; Hydrilla verticillata, watermifoil are 20 clumps/square metre; Potamogeton cristatus Regel et Maack, p.malaianus are 30 clumps/square metre.
Effect of the present invention is:
By this method make up ecological river bed, be suitable for the slow middle-size and small-size river of current of 30-150 centimetres of the depth of waters, the direction of current is not required; It not only can effectively remove the pollutant of river, simultaneously, has also successfully rebuild the river submerged vegetation, for the rivers health construction of ecosystems is laid a good foundation.
Four, description of drawings
The ecological river bed profile of Fig. 1.1. composite interstitial substance bed course, 2. slag layer, 3. peat horizon, 4. soil horizon, 5. water plant, the 6. water surface; Measurement unit: centimetre.
The ecological river bed side view of Fig. 2.1. composite interstitial substance bed course, 2. slag layer, 3. peat horizon, 4. soil horizon, 5. water plant; Measurement unit: centimetre.
Five, the specific embodiment
This method is long 300 meters of Taihu Lake basin, demonstrates in wide 25 meters river course, and its specific embodiment is as follows:
The first step, is determined detailed protocol at on-the-spot investigation; Implement seed and the construction material of plant, engineers and technicians put in place.
In second step, before implementing, principal works needs the place is cleared up with smooth.
In the 3rd step, make up ecological river bed matrix and surface stream wetland matrix part.
In the 4th step, pouring water in the river, makes the water body depth capacity reach 50 centimetres.
In the 5th step, take advantage of canoe to carry out the plantation of submerged plant.
The 6th step, on-the-spot operation and effect monitoring.
At last, because plant has certain death rate, after engineering is finished, need carry out appropriate managerial and maintenance to plant.
Claims (1)
1, a kind of ecological river bed construction method, it is characterized in that this method is in the riverbed through dredging, at first lay one deck composite interstitial substance bed course, 3 centimetres of thickness, building waste by the rubble of clay particle, diameter 1-2 centimetre, diameter 1-2 centimetre is formed, and the ratio of rubble, building waste, clay particle is 6:2:2; On the matrix bed course, make up surface stream wetland; Its vertical stratification is divided into 3 layers, is respectively from bottom to top: slag layer, and 10 centimetres of thickness are made up of diameter 3-5 centimetre slag granules; Peat horizon, 5 centimetres of thickness are made up of diameter 2-3 centimetre peat particle; And soil horizon, 2 centimetres of thickness are by unpolluted soil constitution; Plant planting submerged plant on stream wetland surface, surface, constitute the river aquatic vegetation; Its density is that eel grass, water caltrop are 10 clumps/square metre; Hydrilla verticillata, watermifoil are 20 clumps/square metre; Potamogeton cristatus Regel et Maack, p.malaianus are 30 clumps/square metre; This method is suitable for depth of water 30-150 centimetre the slow middle-size and small-size river of current; It not only can remove the pollutant of river, simultaneously, has also rebuild the river submerged vegetation.
