Description

Device for silt protection}

The present invention relates to a dirt prevention device, and more particularly, to a dirt prevention device for preventing the occurrence of dirty water generated in dredging work in a river or a coast and in construction work.

In the case of lakes, rivers or oceans, which are usually deep, water exhibits a stratified phenomenon divided into several water layers according to depth. The upper part of the water is called the surface layer. The surface water layer is a layer with low density water (high temperature in summer and low temperature in winter). It is mixed evenly with the influence of the wind blowing above the water surface and the relatively high velocity The water temperature is a relatively uniform layer. The middle layer is a layer below the surface layer and has a constant temperature gradient (about 0.9 캜 / m depth). In the middle layer, upward and downward convection of water occurs due to the temperature difference between the upper and lower portions, and the flow rate is comparatively fast. The deep layer (also called the "deep water layer") is a layer in which water having the highest density exists, and is a stable layer in which the water temperature is almost uniform and water up-down convection hardly occurs. In the above water layer, water having a high temperature is formed as a water layer in the summer, and when the season changes in winter, a reverse phenomenon occurs in which water at a low temperature of 4 ° C is formed as a water layer.

The main cause of water pollution that occurs during underwater or waterside construction is the turbid water caused by the soil at the time of construction, and the soil that causes turbid water is present in the middle layer for a long time and is spreading to the surrounding water through this layer. Respectively. This phenomenon is explained by the fact that the vertical convection of water is active in the middle layer, so that the soil does not settle quickly and spreads widely to the surrounding area due to the relatively fast horizontal flow rate.

At this time, the turbid water adversely affects the ecosystem around the construction site.

In order to prevent the turbid water from diffusing into the surrounding area of the construction site, a dirt prevention device is installed in the water. The dirt prevention device is provided with a buoyant body at the top of the dirt prevention membrane made of, for example, And fixing the antifouling film to the underwater floor.

As a related art, Korean Patent Laid-Open Publication No. 2013-0024658 discloses a float floating on the water surface; A dirt preventing film connected to the float and preventing the water from being diffused in the water; A main fixing part fixing the positions of the float and the anticlock layer; And a variable portion for reducing the area of the anticorrosive film so as to maintain the vertical state of the anticorrosive film in water and to reduce the resistance due to wave during wave generation.

However, in the prior art, since the bottom shape of the antifouling film can not be deformed, the antifouling effect is reduced by half because the water is passed between the bottom of the antifouling film and the ground.

In addition, most of the antifouling membranes are made of a polyester film material in a batch so that the material of the antifouling film has a high strength without any damage to the film even in the ocean wave or flow velocity. In the places where there is no flow rate, There is a problem that it is overloaded.

Therefore, it is necessary to develop various anti-dumping devices for solving the above-mentioned problems.
