Description
Technical field
The present invention relates to one kind to prevent suspended matter diffusion technique, more specifically, it relates to which a kind of subtracted using restriction device
The method of suspended matter diffusion in few dredging work.
Background technique
Currently, many suspended matters can be generated during carrying out dredging operation, it, can be right if leaving suspended matter flowing
Ocean pollutes, but in actual operation process, improper due to protecting, and the suspended matter for dredging generation is easy to extending out
It dissipates, the organism around construction, such as fish, shrimp, crab and its young is damaged.
Summary of the invention
The present invention overcomes the suspended matters generated during dredging operation to be easy to external diffusion, the water body of pollution construction surrounding
Deficiency, provide a kind of method for reducing suspended matter diffusion in dredging work using device is limited, produce during dredging operation
Raw suspended matter is not easy to avoid suspended matter to external diffusion and pollutes the water body around construction to external diffusion.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of reduce dredging using restriction device
The method that suspended matter is spread in engineering limits device and includes fence circle made of being enclosed as several baffle assemblies, is arranged adjacent
Flexible inserting column between two baffle assemblies, flexible inserting column include fixed link, lower telescopic rod, upper telescopic rod, lower telescopic rod movable sleeve
In fixed link, upper telescopic rod movable set in lower telescopic rod, it is lower between telescopic rod and fixed link and upper telescopic rod and
Abutting spring is mounted between lower telescopic rod；Baffle assembly includes bottom baffles, lower clapboard, upper spacer, bottom baffles connection
Between adjacent two fixed link, lower clapboard is connected between adjacent two lower telescopic rods, and upper spacer is connected to telescopic rod on adjacent two
Between；Bottom baffles, lower clapboard are equipped with several recirculation holes on upper spacer, install strainer on recirculation hole, bottom baffles and under
It is mutually arranged in a staggered manner between partition and between lower clapboard and upper spacer and part is overlapped；Device will be limited before dredging operation
It being placed in the waters for needing to dredge, the fixed link lower end insertion bottom of flexible inserting column is fixed, and upper spacer upper end is exposed the surface,
Bottom baffles lower end close to water-bed, in dredging operation mechanical gripper protrude into fence corral at waters in, within the scope of fence circle
Dredging operation is carried out, the suspended matter generated during dredging dredging is in fence circle without to external diffusion, mechanical gripper sinks
When process touches upper spacer or lower clapboard, upper spacer and lower clapboard are stirred without catching phenomenon downwards；Using net
Pocket periodically clears up the larger suspended matter in fence circle；Within the scope of fence circle after dredging, with the string bag to floating compared with
Big suspended matter is cleared up, and is then allowed to stand a period of time after suspended matter precipitating in fence circle, will be limited device and is moved away from water body.
During dredging operation, mechanical gripper carries out operation in fence circle, and upper spacer upper end is exposed the surface, bottom baffles
Close to water-bed, the suspended matter of generation is limited in the waters of fence corral synthesis for lower end, without to external diffusion, recirculation hole
Circulation convenient for water body is set, and strainer blocks the outflow of suspended matter.Mechanical gripper sinking watching touch upper spacer or under every
When plate, upper spacer and lower clapboard are stirred without catching phenomenon downwards, and restriction device is effectively prevent to occur toppling over phenomenon
And make suspended matter to external diffusion.Periodically the larger suspended matter in fence circle is cleared up using the string bag；It is clear within the scope of fence circle
It after silt, is cleared up with larger suspended matter of the string bag to floating, it is heavy to suspended matter in fence circle to be then allowed to stand a period of time
Behind shallow lake, device will be limited and move away from water body.The suspended matter generated during dredging operation is not easy to external diffusion, avoid suspended matter to
External diffusion and pollute construction around water body.
