Description
Technical field
The utility model relates to a kind of anti-pollution rail of throwing mud for Dredging Engineering waterborne, is specifically related to a kind of anti-pollution rail that adopts colour bar cloth to make.
Background technology
On lake, coastal waters, riverbed, pile up a lot of mud, while affecting water quality and navigation channel, need to dredge mud, the marine sediments that dredging works waterborne produces or the secondary pollution of mud cause certain destruction to aquatic ecosystem, ecological around impact is mainly contained: (1), dredge the material disturbance of polluted bed mud layer and diffusion aggravation in process, the suspension dredging thing producing causes suspended material in water sharply to increase in a short time, makes water quality deterioration.(2), dredging uncontamination organic suspended matter in process produces and destroys aquatic ecosystem.(3), dredging sanitary sewage, the oil-polluted water that in process, construction ship produces pollutes water environment.Therefore, in dredging works, the dredging thing that in dredged area, sediment deposit is dredged is out transferred to mud dumping area on the water, avoids marine sediments or mud to pollute water body around, but the construction of mud dumping area cofferdam can acquire a certain degree of difficulty, and understand some mud and pass back into lake.
Existing cofferdam can be earth fill cofferdam, earth bag cofferdam.But in the depth of water, surpass the pool of 2 meters, earth fill cofferdam can only excavate on the spot, excavate, fill the diffuse pollution that has just caused mud in process, top, cofferdam is under the erosion repeatedly of wave, need to constantly fill up, the simultaneously rise of water level is to the width of earth fill cofferdam, requirement for height all in continuous variation, and it is too high, uneconomical that this just causes earth fill cofferdam to fill cost.Earth bag cofferdam can reduce the pollution of the process of filling to pool, but high to depth of water requirement, the depth of water surpasses 2 meters just needs personnel to carry out diving operation, and the construction of earth bag needs a large amount of artificial layings in addition, in the situation that current price of labour service is high, also uneconomical.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-pollution rail of throwing mud for Dredging Engineering waterborne, the protection by this anti-pollution rail for dredging works mud dumping area waterborne, can effectively stop mud excessive, prevent secondary pollution of water around.
The object of the invention is to be achieved through the following technical solutions:
A kind of anti-pollution rail of throwing mud for Dredging Engineering waterborne, this anti-pollution rail is formed by the staggered overlap joint in a plurality of colour bar cloth unit, described colour bar cloth unit comprises colour bar cloth, positioning and anchoring bar, buoyant device, on described colour bar cloth, interval arranges positioning and anchoring bar, and adjacent two positioning and anchoring bars are separately positioned on colour bar cloth both sides; Colour bar cloth bottom and positioning and anchoring bar bottom are fastenedly connected, and colour bar cloth top is loosely connected with positioning and anchoring bar; Interval, colour bar cloth top arranges buoyant device.
The lap length of adjacent two colour bar cloth unit is 2～4m, is preferably 3m.
The length of the colour bar cloth of each colour bar cloth unit is 40～60m, is preferably 50m.The height of colour bar cloth arranges according to the water level in hydrological data over the years and stage, to guarantee that the top of colour bar cloth exceeds the water surface.
Described colour bar cloth is selected polyethylene colour bar cloth or polypropylene colour bar cloth, is preferably polyethylene colour bar cloth.Commercially available colour bar is covered with foot channel to intensity >=2100N/5CM, latitudinal strength >=1600N/5CM, water pressure resistance value >=2000MM water column, and intensity is large, for the fence of mud dumping area, can resist Lidar Equation, also can play waterproof action.
On described colour bar cloth, interval 3～25m arranges positioning and anchoring bar; Described positioning and anchoring bar is bamboo pole or steel pipe; The length of described positioning and anchoring bar is 12m; The diameter of described bamboo pole is 10～12cm, and the diameter of described steel pipe is 30～50mm.When positioning and anchoring bar is selected bamboo pole, preferred interval 3m arranges positioning and anchoring bar; When positioning and anchoring bar is selected steel pipe, the spacing of adjacent steel pipe suitably strengthens, and is preferably 10～25m.Can colour bar cloth top be loosely connected with positioning and anchoring bar by nylon wire; Also can be by connecting ring being set on colour bar cloth top, the internal diameter of connecting ring is greater than the diameter of positioning and anchoring bar, by connecting ring, colour bar cloth top is set on positioning and anchoring bar and is realized loose connection; By colour bar cloth top and positioning and anchoring bar, be loosely connected and guarantee that colour bar cloth top can be with the rise automatic lifting of water level.
Described adjacent floating power apparatus is spaced apart 1～5m.Described buoyant device is a kind of or both combinations in ball float, cystosepiment.Preferably, at downward 8～12cm place, colour bar cloth top, every 1m, tie up 3 ball floats or 3 blocks of cystosepiments, and ball float or cystosepiment are wrapped in colour bar cloth, the buoyancy producing by ball float or cystosepiment guarantees that colour bar cloth top bubbles through the water column, and can block the diffusion of mud.The diameter of described ball float is the polyethylene ball float of 8～12cm, diameter of bore 1.2～1.8cm.
Further preferred, described colour bar cloth bottom interval 1～5m arranges pendant piece, guarantees that colour bar cloth bottom is close to mud face, can not make sewage ooze out from bottom.More convenient in order to install, reduce pendant piece pendant simultaneously and cause damage at bottom pulling colour bar cloth, described pendant piece is preferably wrapped in colour bar cloth, and adjacent pendant interblock distance is 1m.Described pendant piece is preferentially selected concrete block.
The utility model is applied to Dredging Engineering waterborne while throwing mud antifouling: apart from the mud extraction mouth of pipe 200～300m place, according to the situation of water-bed mud face, positioning and anchoring bar is inserted to 2～3m in mud, by the staggered overlap joint in a plurality of colour bar cloth unit, form anti-pollution rail, can effectively stop mud excessive, prevent secondary pollution of water around.
The beneficial effects of the utility model:
The utility model is economical and practical, and it is antifouling that the Dredging Engineering waterborne that is suitable for water field of big area is thrown mud, can effectively stop mud excessive, prevent secondary pollution of water around, and be conducive to the discharge of top layer clear water after suspension precipitation.
The colour bar cloth low price that the utility model adopts, draws materials conveniently, and intensity is high, in use procedure, can not produce pollution problem to pool.
The utility model adopts the staggered overlap joint of segmentation colour bar cloth, can increase or reduce colour bar cloth unit according to the actual needs of job site, and it is convenient to lay, remove, and has reduced labour; In antifouling process, when as current in fishing boat according to production requirement, can directly at cohesive position, open, recover again after current, and fixed cofferdam reaches and cannot meet this generic request.Can disperse fence stressing conditions simultaneously, effectively prevent because Lidar Equation causes colour bar cloth integral inclination, guarantee that colour bar cloth can be embedded under water by mud stretch bending; And directly adopt whole piece colour bar cloth to form fence, there is the defect that integral body is stressed, easily cause chain effect.
The utility model colour bar cloth top is loosely connected with positioning and anchoring bar, can follow SEA LEVEL VARIATION automatic lifting, reaches once and lays and just can meet the demands.
Because per stage of direction of stormy waves is not the same, so adjacent positioned anchor rod is separately positioned on to colour bar cloth both sides in the inventive method, alleviates the impact of both sides stormy waves on colour bar cloth.
