It will be appreciated that the present utility model provides an anti-fouling curtain comprising a curtain of silt 10, the curtain of silt 10 being perpendicular to the body of water for blocking the diffusion of silt water produced by the dredged hydraulic fill. In order to enable the sludge curtain 10 to maintain a vertical state in water, the top of the sludge curtain 10 is curled and fixed, and in particular, the top of the sludge curtain 10 may be sewn and fixed after being bent. The bent portion forms a cylindrical cavity into which the float 20 is inserted. Further, the float 20 is a cylinder, and the size of the bent portion at the top of the sludge curtain 10 may be set according to the sectional size of the float 20 so that the float 20 can be inserted.

Further, in order to prevent the sludge curtain 10 from being blown to be displaced by wind and waves, etc., the sludge curtain 10 may be fixed by the prefabricated weights 30. Specifically, a metal keyhole 11 is provided at a side of the sludge curtain 10, one end of the rope 40 is connected to the metal keyhole 11, and the other end is connected to the prefabricated weight 30. The prefabricated drop body 30 is sunk at the water bottom to fix the silt curtain 10. Both the front and back sides of the sludge curtain 10 can be connected to the prefabricated weights 30. Illustratively, one prefabricated weight body 30 is respectively connected to the front and the back of both sides of a sludge curtain 10, and the sludge curtain 10 is fixed by the 4 prefabricated weight bodies 30 so as to slightly drift within a certain range.

In another alternative embodiment of the present utility model, the material of the float 20 is polystyrene.

It will be appreciated that polystyrene is commonly used in foam plastic products and is primarily designed to rely on its own upward buoyancy to resist the downward pulling force of the prefabricated drop 30 on the float 20 caused by the horizontal forces of wind and waves on the float 20 and the self weight of the silt curtain 10, so that the top end of the silt curtain 10 remains above the water surface at all times.

Illustratively, in the water depth range of 0-12 m, under the action of wind and waves, the dead weight of the prefabricated falling body 30 and the silt curtain 10 generates downward maximum pulling force on the buoy 20, which is 393N/m. At this time, the buoyancy force generated by the cylindrical buoy 20 with the section diameter of 300mm can reach 546N/m, and the requirements can be met. Further, each section of the float 20 has a length of 2.4m, which is convenient for transportation and installation.

The silt curtain 10 in the embodiment of the utility model is woven by high-strength polyester fibers, and the tensile strength of the silt curtain can reach 150kN/m.

Further, the maximum tensile force of the wind wave on the dirt blocking curtain is 54.5kN/m. The single length of the silt curtain 10 is 20m, and the depth is determined according to the water depth of the construction water area. The depth of the straightened sludge curtain 10 is 1-2m from the water bottom.

In another alternative embodiment provided by the present utility model, referring to fig. 3 and 4, the prefabricated drop body 30 includes a concrete block 31 and reinforcing bars 32 bent in a U shape, and both ends of which are fixed in the prefabricated concrete block 31;

Specifically, the prefabricated weights 30 include concrete blocks 31, and after bending the reinforcing bars 32 into a U shape in the process of casting the concrete blocks 31, both ends are inserted into the concrete blocks 31. After the concrete mass 31 is solidified, the reinforcing bars 32 form tie-down joints. And is connected to one end of the rope 40 by a U-shaped buckle 60. Similarly, the other end of the rope 40 is also connected with the metal keyhole 11 of the sludge curtain 10 through the U-shaped buckle 60.

Further, the weight of the prefabricated drop body 30 may be set according to the depth of the application water area. Illustratively, in the range of 0-8m, the maximum upward pulling force of the prefabricated weight body 30 due to wind waves and the like is 22.89kN, and 1 x 1 concrete blocks 31 with dead weight of 24kN can be adopted. In the water depth range of 8-12m, the maximum upward pulling force generated on the prefabricated falling body 30 due to wind waves and other factors is 31.8kN, and 1.2m 1m concrete blocks 31 can be adopted, and the dead weight is 34.6kN.

Further, the rope 40 connecting the prefabricated weights 30 and the sludge curtain 10 may be nylon ropes.

The diameter of the nylon rope is 24mm, the maximum tensile strength of the nylon rope is 50kN, and the maximum tensile force generated by the nylon rope due to the influence of stormy waves is 44kN, so that the requirement of the tensile force can be met.

In an alternative embodiment provided by the utility model, the angle formed by the prefabricated weights 30 and the silt curtain 10 is 45-70 degrees.

Specifically, the length of the intersecting direct connection of the prefabricated weights 30 and the string body 40 connected to the sludge curtain 10 is 1-2m. At the time of tide rising, the floats 20 and the silt curtain 10 float up simultaneously along with the tide level, the floats 20 are always kept on the water surface, and at the time of low tide level, the silt curtain 10 is always in a free sagging state due to the gap between the silt curtain 10 and the seabed of 1-2m.
