Description
Technical field
The present invention relates to ecological restoration technical fields, intercept more particularly, to a kind of grenadine and improve river water body transparency system
System.
Background technique
Important component and main primary producer of the submerged plant as water ecosystem, to form complexity
Food chain provides food source, habitat and other necessary conditions, is that aqueous bio diversity is rely the basis of maintenance.Change sentence
It talks about, submerged plant is the key factor for constructing the poisons in freshwater ecosystem of stable structure, operational excellence.Therefore, restore and
Rebuild the important link that water body Submerged plant communities are preventions with administer water eutrophication work.
It is planted under the conditions of river course environment the initial stage of planting submerged plant process, river water body transparency is to influence survival rate most
Key factor, and concentration of suspension is the principal element for influencing water transparency.That is, river water body flow disturbance bed mud and on
The carrying for swimming across water suspended particulate can improve the concentration of suspension of river water body, and then water transparency is caused to reduce.
Summary of the invention
It is intercepted the object of the present invention is to provide a kind of grenadine and improves river water body transparency system, it has can be preferable
The characteristics of reducing river concentration of suspension, and then improving submerged plant planting condition.
The technical scheme adopted by the invention is that: grenadine intercepts the river water body transparency system that improves, and the grenadine intercepts
Improving river water body transparency system includes at least one interception unit, and each interception unit includes:
--- bottom of river channel is fixed in 1 or 2 fixed link, fixed link lower end；
--- 1 fine-structure mesh yarn；
--- several floating balls, floating ball float on the water surface in river；
--- several mass, mass are sunken to the bottom in river；And
The vertical avris of fine-structure mesh yarn is fixed in fixed link；
The upper side edge of fine-structure mesh yarn is fixedly connected on floating ball；
The lower side of fine-structure mesh yarn is fixedly connected on mass.
Adjacent interception unit interlaced arrangement.
The mass is gabion, and gabion includes fabric bag body and is filled in the intracorporal rubble of bag and/or cobble.
The fixed link is prepared using galvanized pipe.
The floating ball is prepared using polystyrene material.
Grenadine of the invention, which intercepts, improves river water body transparency system advantageously:
1, river concentration of suspension can be preferably reduced, and then improves submerged plant planting condition.The present invention passes through benefit
The mass for effectively being intercepted suspended matter with fine-structure mesh yarn, and being sunken to bottom of river channel reduces agitation of the water body flow to bed mud, thus
Improve submerged plant planting condition.It is observed through actual use, river downstream water transparency 20-30cm can be improved.
2, operation is easy, convenient for construction.Used unit of the present invention is less, and structure is relatively simple, is then convenient for operation and applies
Work.
3, without secondary pollution.The present invention uses physics mode, is different from chemical flocculation method, not only effect lasts, and not
Secondary pollution can be generated.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:

Specific embodiment
Embodiment
See figure 1 and figure 2: grenadine, which intercepts, improves river water body transparency system, including at least one interception unit.Often
A interception unit includes: the components such as 1 or 2 fixed link 10,1 fine-structure mesh yarns 20, several floating balls 30, several mass 40.Its
In, bottom of river channel is fixed in 10 lower end of fixed link, and floating ball 30 floats on the water surface in river, and mass 40 is sunken to the bottom in river
Portion.And the vertical avris of fine-structure mesh yarn 20 is fixed in fixed link 10, the upper side edge of fine-structure mesh yarn 20 is fixedly connected on floating ball 30
On, the lower side of fine-structure mesh yarn 20 is fixedly connected on mass 40.Wherein, the vertical avris of so-called fine-structure mesh yarn 20 refers to thin
The left side side and/or the right side of grenadine 20.That is, each interception unit use 1 fixed link 10 when, the left side of fine-structure mesh yarn 20 or
Right edge is fixedly connected with the fixed link 10；When each interception unit uses 2 fixed links 10, the left side side of fine-structure mesh yarn 20 and the right
Side is respectively fixedly connected in a fixed link 10.Meanwhile so-called fine-structure mesh yarn 20, refer to that mesh number is the net of 200~300 mesh
Yarn.In this way, fine-structure mesh yarn has effectively intercepted suspended matter, and mass is sunken to bottom of river channel, reduces water body flow and stirs bed mud
It is dynamic, so as to improve the planting conditions of submerged plant.Certainly, it needs periodically to clean or replace fine-structure mesh yarn, cleaning way
It is so that biofilm layer is fallen off by beaing, and the period cleaned or replaced determines according to the stopping state of fine-structure mesh yarn.
Optimization:
Adjacent interception unit interlaced arrangement.So-called interlaced arrangement refers to that interception unit seen from above, adjacent is in
"the" shape distribution.For example, an interception unit of upstream leans on the left side in river, and is set on the right side of river and reserve channel of navigating；
Meanwhile the right side in river is leaned in downstream close to an interception unit of the interception unit, and channel of navigating is reserved on the left of river.Tool
Body is as shown in Figure 2.In other words, as needed, whether interception unit can be multiple tracks, and need to navigate according to river, intercept
Unit can be covered in river cross section, can also reserve position of navigating.
Mass 40 is gabion, and gabion includes fabric bag body and is filled in the intracorporal rubble of bag and/or cobble.This
Sample, mass 40 can be fitted closely with bottom of river channel, on the one hand can preferably be fixed fine-structure mesh yarn, on the other hand be passed through resistance
Stream can slow down disturbance of the bottom of river channel water body flow generation to bed mud.
Fixed link 10 is prepared using galvanized pipe, and floating ball 30 is prepared using polystyrene material.In this way, reduce material at
This.
Effect example
It is tested on the spot by the way of described in the embodiment as follows:
1, river is oriented in Ningbo City Beilun District, lays 1 interception unit from the every interval 15m in downstream is above swum over to, sets 8 altogether.
Interception unit interlaced arrangement, the channel width about 5m that navigates that unilateral side is reserved, 30~35m of river width, flow velocity of river 0.1~
0.2m/s.The results are shown in Table 1:
Table 1:
2, in the Ningbo City Yinzhou District village Xi Jianggu river, 1 interception unit is laid from the every interval 15m in downstream is above swum over to, altogether
If 8.Interception unit is all covered in river cross section.There is a small amount of agricultural drain in upstream, because silt carries suspended matter relatively
It is high.8~10m of river width, 0.1~0.2m/s of flow velocity of river.The results are shown in Table 2:
Table 2:
It can be seen that intercept using grenadine of the invention from the above Tables 1 and 2 and improve river water body transparency system to river
After road is administered, water transparency has obtained very big improvement.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
