Description

Technical Field

[0001] The utility model belongs to the technical field of anti-fouling in marine construction, in particular to an anti-fouling device suitable for an overflow outlet of a blown filling mud receiving area. Background Art

[0002] The amount of dredged soil generated during the construction of large-scale water transport projects such as waterways is large. When it comes to landfill, how to reduce the concentration of suspended sediment at the overflow outlet of the filling area is directly related to the impact of the filling construction on the water environment of the sea area. At present, the main method for controlling the concentration of suspended sediment is to set up anti-fouling curtains at the overflow outlet to intercept sediment, thereby effectively controlling the spread of sediment to deep water areas.

[0003] However, with current technology, it is difficult to fully intercept high-concentration suspended sand by relying solely on the setting of a single-layer anti-fouling curtain. When the suspended sand is discharged from the overflow port, it will not have enough sedimentation time and will eventually accumulate on the anti-fouling curtain in large quantities. Finally, with the action of water flow, some sand will still pass through the curtain and spread to the deep sea area. Utility Model Content

[0015] The anti-fouling device suitable for the overflow outlet of the blown filling mud receiving area provided by the utility model has the beneficial effect that: through the force transmission component, the first anti-fouling curtain is shaken under the overflow action, so as to easily promote the falling of the mud accumulated in itself, so that the mud is formed to form a large amount of sedimentation before it goes out of the first anti-fouling curtain; by setting the second anti-fouling curtain, a buffer zone is formed between it and the first anti-fouling curtain, and the movement speed of the sand-containing water flow is slowed down during the spreading process here, so as to provide sufficient time for the precipitation of the remaining mud, so as to control the amount of mud that finally spreads into the sea water as a whole; compared with the prior art, the utility model has a better effect on mud interception.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0025] Reference Figure 1 An embodiment of the utility model provides an anti-fouling device suitable for an overflow port of a blown filling mud receiving area, which is used to intercept sand-containing mud water discharged from the overflow port. The device includes a first anti-fouling curtain 1, a second anti-fouling curtain 2 and a force transmission component 3, and the arrangement relationship thereof is as follows:

[0026] The first anti-fouling curtain 1 and the second anti-fouling curtain 2 are used to be distributed in sequence along a direction away from the overflow port, and are used to form a perimeter around the overflow port;

[0027] The force transmission component 3 is at least connected to the first anti-fouling curtain 1, and at least a part of it is located in the direct impact area of ​​the overflow port;

[0028] Based on this, the force transmitting component 3 needs to have buoyancy on the water so that it floats on the paper, such as Figure 1 As shown in the figure, the force transmission component 3 can adopt a rope structure, on which a plurality of buoys are arranged in sequence to keep the whole body floating in the water. When the overflow port is draining, the water body at the overflow port is impacted and moved, so that the force transmission component 3 moves in the water with the movement of the water surface, so as to drive the first anti-fouling curtain 1 to shake through the connection effect. In the process of spreading of sandy muddy water, part of the mud sinks, and the part that does not sink is finally intercepted for the first time by the first anti-fouling curtain 1, so that mud accumulates on it, and the shaking can promote this part of the mud to be separated from the first anti-fouling curtain 1. Separated, it sinks, thereby reducing the phenomenon of mud and sand passing through the first anti-fouling curtain 1 and entering the periphery driven by subsequent water flow; the mud and sand that pass through the periphery will enter the buffer zone formed between the first anti-fouling curtain 1 and the second anti-fouling curtain 2, and the suspended mud and sand in this area are basically not affected by the impact of water outflow from the overflow port, diffuse more slowly, and settle for a longer time. The buffer zone provides sufficient sedimentation time for this part of the mud and sand, so that it has enough time to settle to the seabed, and finally no obvious turbidity can be seen outside the second anti-fouling curtain 2, thereby achieving an effective spread control of the suspended mud and sand.

[0029] Further, see Figure 1 The force transfer component 3 is connected to the overflow port in a transversely extending manner to form an interception-shaped distribution at the overflow port, thereby obtaining the drainage force to the greatest extent. The two ends of the force transfer component 3 are respectively connected to the positions close to the two ends of the first anti-fouling curtain 1, thereby fully transferring the force to the first anti-fouling curtain 1, thereby effectively shaking off the mud and sand attached thereto.

[0030] Further, see Figure 2 The first anti-fouling curtain 1 and the second anti-fouling curtain 2 are both composed of a plurality of curtain body units, and the curtain body unit includes a curtain 4. Two sides of the curtain 4 are respectively provided with a buoy 5 and a counterweight sandbag 6. The counterweight sandbag 6 can effectively ensure that the bottom side of the curtain 4 contacts the seabed, and the buoy 5 can effectively ensure that the upper side of the curtain 4 is fully extended to the sea surface, thereby realizing an effective interception of seawater in the longitudinal direction.

[0031] Further, see Figure 2Regarding the connection method between the curtain bodies, connecting ropes 7 are provided at the corners of the curtain 4, and buckles 8 are provided on them. Any two adjacent curtains 4 are connected by the cooperation of the connecting ropes 7 and the buckles 8; so that the two curtains 4 can be connected into a whole through the connecting ropes 7 and the buckles 8; Velcro can also be sewn from top to bottom at the overlapping position of the two curtains 4 to better improve the connection effect between the two curtains 4, so as to form a whole.

[0032] Further, see Figure 3 The utility model also includes an anchor rod 9 fixedly arranged in the water and a buoyancy member 10 movably arranged on the anchor rod 9. The buoyancy member 10 can be an annular floating ball, which can be sleeved on the anchor rod 9. The length of the anchor rod 9 needs to be greater than the depth of the sea water. A plurality of threading rings 11 are fixedly arranged on the anchor rod 9. A combination of an anchor rod 9, a buoyancy member 10 and a plurality of threading rings 11 on the anchor rod 9 is a combination. There are two such combinations, which are respectively located at the two end positions of the first anti-fouling curtain 1, and are used to cooperate with the connection between the two ends and the cofferdam area. Specifically, the connecting rope 7 located at the end of the first anti-fouling curtain 1 passes through a plurality of threading rings 11 and is connected to the buoyancy member 10; so that when the buoyancy member 10 moves up, the connecting rope 7 is pulled The connecting rope 7 is tightened so that the enclosed area of ​​the first anti-fouling curtain 1 is appropriately reduced. Conversely, when the buoyancy member 10 moves downward, the connecting rope 7 is released slowly, so that the enclosed area of ​​the first anti-fouling curtain 1 is appropriately increased. In practice, due to the factors of rising and falling tides, the actual length of the anti-fouling curtain needs to be adjusted accordingly. After the tide falls, the first anti-fouling curtain 1 is close to the cofferdam area and is easy to run aground on the cofferdam revetment, resulting in a smaller enclosed range. Therefore, through the cooperation of the buoyancy member 10, the connecting rope 7 is controlled to be released slowly as the sea level moves downward, thereby loosening the first anti-fouling curtain 1 and increasing its enclosed area accordingly. Similarly, at high tide, the connecting rope 7 is pulled by the buoyancy member 10, so that the enclosed area of ​​the first anti-fouling curtain 1 shrinks accordingly.

[0033] Further, see Figure 1The first anti-fouling curtain 1 is arranged in a semicircular shape with a diameter of 50 meters. The water outlet speed of the overflow port is generally high, and its flow rate is generally 1.5-2m / s, and the water impact distance is about 30m, so the water outlet will directly affect the range within a radius of 30m. The flow rate outside the range of 30m is greatly slowed down and begins to exchange and mix with the raw water to form a mixing zone, and the suspended sediment begins to settle naturally. The radius of 50 meters can fully ensure that the first anti-fouling curtain 1 will not be directly impacted by the outward flow of the water flow, thereby ensuring the stability of the setting of the first anti-fouling curtain 1. The second anti-fouling curtain 2 is arranged in a semicircular shape. It is square, with a length of 200 meters and parallel to the cofferdam area. For some areas, during high and low tides, the suspended sediment diffusion is distributed along a strip, which is roughly consistent with the length direction of the cofferdam. The square enclosure is arranged parallel to the diffusion direction and is basically consistent with the diffusion direction of the suspended sediment, which is more conducive to sedimentation. The width of the second anti-fouling curtain 2 is 80 meters, and each of the curtains 4 is at least 20 meters long and at least 2.5 meters wide. The 20-meter length can fully guarantee the overall connection firmness, and the 2.5-meter width can fully cope with the depth requirements of the seawater in the entire overflow area at the maximum increase.

[0034] Furthermore, several anchoring points are arranged in the paths enclosed by the first anti-fouling curtain 1 and the second anti-fouling curtain 2. The distance between any two adjacent anchoring points in the path of the second anti-fouling curtain 2 is 40 meters. The distance of 40 meters requires that approximately 8 anchoring points be arranged, thereby ensuring a relatively low construction difficulty while fully coping with the stability of the anchoring points when arranged in water.

[0035] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
