Description

Technical Field

[0001] The invention relates to the field of water-related engineering, and in particular to a positioning device for an anti-fouling curtain and a construction method thereof. Background Art

[0002] In dredging projects, the process of dredging, transporting mud and filling overflow often leads to the disturbance and diffusion of the original polluted sediment layer and non-polluted native soil particles. This disturbance will cause the concentration of suspended matter in the water to rise sharply in a short period of time, causing varying degrees of pollution to the surrounding waters. In addition, due to the complexity of construction operations and their wide distribution, dredging projects have a wide range of pollution at sea, further posing greater challenges to the environment. In particular, when some sediment layers containing toxic and hazardous substances are disturbed, the diffused pollutants will seriously threaten the marine ecological environment and water quality safety.

[0003] In current engineering practice, anti-pollution curtains are usually set up around the construction area to prevent the spread of silt. However, the application effect of anti-pollution curtains has certain limitations in different construction environments. When the construction site is far from the coast and is in a sea area with large tidal range and strong winds and waves, the fixation and stability of the anti-pollution curtains become difficult. Under such harsh marine conditions, anti-pollution curtains are often difficult to fix effectively and are easily impacted by strong currents, waves and tides. These external forces may cause the anti-pollution curtains to be damaged or displaced, thereby losing their due anti-pollution effect, and silt and pollutants spread to the surrounding waters. Not only that, after the anti-pollution curtain fails, the diffusion rate may be further aggravated, expanding the scope of pollution and increasing the difficulty of control. This situation is particularly common in offshore dredging projects, bringing additional environmental management challenges to construction units.

[0004] In addition, traditionally, construction units usually use concrete blocks to fix anti-fouling curtains or other equipment, but this practice also has some significant disadvantages during sea transportation. First, the weight of concrete blocks is large, which increases the total weight of the ship, thereby increasing fuel consumption and transportation costs. At the same time, if the weight of concrete blocks is unevenly distributed, it will also affect the stability of the ship, especially in sea areas with large waves, which may cause the ship to shake more severely and pose a safety risk. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem that traditional anti-fouling curtains in the prior art are fixed by concrete blocks, while when ships transport concrete blocks, the concrete blocks are heavy and difficult to fix during transportation, which increases the transportation risk. Therefore, a positioning device for an anti-fouling curtain is provided, and a construction method for the anti-fouling curtain is also proposed.

[0006] In a first aspect, the present invention provides a positioning device for an anti-fouling curtain, comprising a pair of limiting parts, one end of which is connected to the anti-fouling curtain and the other end is connected to the seabed; and also comprising a steel section, which is located in the area below the anti-fouling curtain, one end of which is connected to the seabed and the other end is connected to the anti-fouling curtain, and the steel section is vertically arranged in the seabed.

[0007] The present invention is a positioning device for an anti-fouling curtain. By symmetrically arranging limiting parts on both sides of the anti-fouling curtain, and the limiting parts being directly connected to the seabed at one end away from the anti-fouling curtain, the anti-fouling curtain can be limited by the traction force of the two limiting parts after installation, and because the limiting parts are symmetrically arranged, the limiting parts can evenly distribute the force applied to the anti-fouling curtain, avoiding the problem of stress concentration, which may cause the limiting parts on one side to break; and the anti-fouling curtain is also provided with a steel section. Compared with traditional concrete blocks, the steel section is lighter, which reduces the transportation burden, reduces the fuel consumption and transportation cost of ships, and the steel section has high rigidity and strength and is vertically arranged in the seabed, so that it can provide more stable support. Compared with concrete blocks, steel parts are more solid under the impact of strong water currents and waves at sea, and can avoid the movement or displacement problem of traditional concrete blocks caused by uneven weight distribution or water flow impact, thereby improving the stability of the anti-fouling curtain; one end of the steel part is connected to the seabed and the other end is connected to the anti-fouling curtain, which not only determines the installation position of the anti-fouling curtain, but also has a traction effect on the anti-fouling curtain. The setting of the steel part can effectively disperse the water flow impact force on the anti-fouling curtain; at the same time, the steel part cooperates with the symmetrically arranged limiting parts, which can effectively distribute the force on the anti-fouling curtain to the steel part and the limiting part, thereby improving the stability of the anti-fouling curtain and avoiding the displacement of the anti-fouling curtain after being impacted; the present invention improves the stability of the anti-fouling curtain in seawater by arranging the limiting parts on the anti-fouling curtain, and also lays steel parts on the seabed to position the anti-fouling curtain to prevent the anti-fouling curtain from being displaced, and the anti-fouling curtain is fixed by replacing the traditional concrete blocks with steel parts, so that the transportation risk of the ship during transportation is reduced.

[0008] Preferably, the anti-fouling curtain comprises a self-floating body, the self-floating body, a skirt is provided at the lower end of the self-floating body, and a counterweight is provided at the lower end of the skirt.

[0009] The skirt can float on the sea by providing a self-floating body; a counterweight is provided at the lower end of the skirt to ensure that the skirt can be unfolded in the seawater to achieve an interception effect.

[0010] Preferably, the buoyancy of the self-floating body is greater than the gravity of the counterweight.

[0011] This arrangement is to prevent the entire self-floating body from being dragged into the water by the counterweight due to the counterweight being too heavy, causing the anti-fouling curtain to fail.

[0012] Preferably, the limiting portion includes a floating member, which is connected to the self-floating body; the limiting portion also includes an anchor, one end of which is connected to a connecting member, one end of which is connected to the anchor and the other end is connected to the self-floating body.

[0013] The anchor is connected to the self-floating body through a floating part. On the one hand, when the anchor is recovered later, the lowering position of the anchor can be accurately found according to the floating part; on the other hand, connecting the floating part to the self-floating body can improve the buoyancy of the entire anti-fouling curtain; the anchor is set so that after the anti-fouling curtain is impacted by the water flow, the anchor can use its own gravity to embed into the seabed and fix it, thereby improving the stability of the anti-fouling curtain.

[0014] Preferably, a reinforcement portion is provided on the skirt, and the reinforcement portion is arranged in a direction consistent with the water flow direction.

[0015] Preferably, the reinforcement portion includes a first reinforcement belt, the reinforcement portion includes a second reinforcement belt, and the first reinforcement belt and the second reinforcement belt are alternately arranged.

[0016] By arranging the first reinforcement belt and the second reinforcement belt on the skirt body, and staggering the first reinforcement belt and the second reinforcement belt, it is ensured that the skirt body can effectively distribute the force after being impacted by the water flow, avoiding uneven force at various positions on the skirt body, causing the skirt body to flip over, etc., thereby reducing the interception efficiency of the anti-fouling curtain.

[0017] Preferably, the steel section is an I-beam.

[0018] Preferably, a warning light is provided on the self-floating body.

[0019] Preferably, the skirt body is made of a water-permeable filter cloth material, and the strength of the filter cloth is greater than or equal to 45 KN / m.

[0020] The filtering performance of the entire anti-pollution curtain is improved, and the mud and sand are effectively intercepted.

[0021] Preferably, the anchor is made of ageing-resistant and corrosion-resistant material.

[0022] In a second aspect, the present invention provides an anti-fouling curtain construction method, comprising the above-mentioned anti-fouling curtain positioning device, and also comprising a steel sheet pile machine for anti-fouling curtain construction, wherein the steel sheet pile machine is provided with an elastic clamp;

[0023] The construction method includes the following steps:

[0024] S1, selecting the location of the steel part;

[0025] S2, using an elastic clamp to clamp the steel profile, and starting a steel sheet pile driver at a driving position to drive the steel profile;

[0026] S3, after the steel profile is driven and fixed, the steel sheet pile driver is started to release the connection between the elastic clamp and the steel profile;

[0027] S4, transporting the anti-fouling curtain to the steel member for installation;

[0028] S5. Complete the construction.

[0029] The present invention discloses a method for constructing an anti-fouling curtain. The anti-fouling curtain of the method improves the stability of the anti-fouling curtain through a limiting part and a steel section; and through preliminary survey and scheme formulation, it is ensured that the specifications and layout of the anti-fouling curtain match the on-site environment, effectively avoiding environmental adaptation problems and improving the anti-fouling effect; a steel sheet pile driver is used to drive the steel section to ensure its accurate fixation at the proposed position, thereby realizing the rapid installation of the anti-fouling curtain; the anti-fouling curtain is transported and installed after the steel section is fixed, thereby optimizing the construction process, reducing on-site adjustment time and improving the overall installation efficiency; the steel section is clamped and driven by an elastic clamp, and after the driving is completed, the friction between the steel section and the seabed is used so that the connection of the elastic clamp can be automatically released after the piling is completed, without the need for additional manual operation, thereby simplifying the construction process and improving efficiency; since the connection between the steel section and the elastic clamp relies on the action of the elastic section, the clamp can be automatically detached after the piling is completed, thereby reducing the safety risks during manual operation.

[0030] Preferably, the elastic clamp includes an installation cavity, the installation cavity is sleeved on the outside of the steel part, the installation cavity is movably connected with a pressing device, one end of the pressing device abuts against the steel part and the other end is located outside the installation cavity.

[0031] Preferably, the pressing device comprises a pressing plate, one side of the pressing plate abuts against the steel member, and the other side is provided with a plurality of screws, a guide column is provided between two adjacent screws, and the pressing device comprises a force-bearing plate, and the force-bearing plate is movably connected with the screws and the guide columns respectively;

[0032] The guide column is sleeved with a spring on the outside, one end of the spring is connected to the lower pressure plate, and the other end is connected to the force-bearing plate;

[0033] A nut is provided at the top of the screw rod, the bottom of the nut abuts against the top of the force-bearing plate, and the nut is used to drive the force-bearing plate to move toward the lower pressure plate;

[0034] The spring is used to control the lower pressing plate to apply force to the steel part.

[0035] Preferably, the steps of connecting the elastic clamp and the steel section are as follows:

[0036] The first step is that the operator loosens the nut so that the spring on the guide column is in a relaxed state;

[0037] In the second step, the operator sleeves the steel part with the installation cavity, and abuts the steel part with the lower pressing plate;

[0038] The third step is to tighten the nut, and the nut drives the force plate to press down, and the force plate drives the spring connected to itself to press down during the downward pressure;

[0039] Step 4. As the nut is further tightened, the spring is compressed, and at the same time, the lower pressure plate is driven to apply downward pressure to the steel section, so that the steel section fits tightly against the installation cavity and the lower pressure plate, ensuring that the steel section is firmly fixed.

[0040] Step 5. Adjust the tightness of the nut until the lower pressure plate applies appropriate clamping force to the steel section to ensure a firm and stable connection.

[0041] Step 6: Once the operator confirms that the elastic clamp is connected to the steel part and the entire device is stable, the operation can be completed.

[0042] Preferably, in the steps S1 and S2, the water level and water flow information of the on-site environment are collected and analyzed before construction to determine the number and location of the anti-fouling curtains to be installed.

[0043] Preferably, the process of clamping the steel profile by the elastic clamp and releasing the connection between the steel profile and the elastic clamp after the steel profile is installed is as follows:

[0044] The operator slowly inserts the steel profile into the seabed to ensure that the bottom of the steel profile can penetrate into the seabed; as the steel profile gradually penetrates deeper into the seabed, the friction of the seabed on the steel profile continues to increase until it reaches a critical value. When the friction of the seabed is greater than the clamping force of the elastic clamp on the steel profile, the clamping force can no longer keep the steel profile in place. When the friction exceeds the clamping force, the steel profile will naturally separate from the elastic clamp, completing the process of releasing the connection.

[0045] By utilizing the friction between the steel section and the seabed, the elastic clamp can be automatically released after the piling is completed without the need for additional manual operation, thus simplifying the construction process and improving efficiency. Since the connection between the steel section and the elastic clamp relies on the action of the elastic part, the clamp can be automatically detached after the piling is completed, reducing the safety risks during manual operation.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The present invention is a positioning device for an anti-fouling curtain, by symmetrically arranging limiting parts on both sides of the anti-fouling curtain, and the limiting parts are directly connected to the seabed at one end away from the anti-fouling curtain, so that the anti-fouling curtain can be limited by the traction force of the two limiting parts after installation, and because the limiting parts are symmetrically arranged, the limiting parts can evenly distribute the force applied to the anti-fouling curtain, avoiding the problem of stress concentration, which may cause the limiting parts on one side to break; and the anti-fouling curtain is also provided with a steel section. Compared with traditional concrete blocks, the steel section is lighter, which reduces the transportation burden, reduces the fuel consumption and transportation cost of ships, and the steel section has high rigidity and strength and is vertically arranged in the seabed, so that it can provide more stable support.

[0063] Example 1

[0064] like Figure 1 and Figure 2As shown, a positioning device for an anti-fouling curtain comprises an anti-fouling curtain placed in the sea, the anti-fouling curtain is provided with at least two limiting parts 3, and the limiting parts 3 are symmetrically arranged with the anti-fouling curtain as a symmetry axis, one end of each limiting part 3 is connected to the anti-fouling curtain, and the other end of the limiting part 3 is connected to the seabed. The advantage of such an arrangement is that when the anti-fouling curtain is impacted by the water flow when working in the seawater, the impact force on the anti-fouling curtain can be evenly distributed through the two symmetrically arranged limiting parts 3, effectively ensuring the structural stability of the anti-fouling curtain, and because the limiting parts 3 are symmetrically designed, there will be no situation in which one of the limiting parts 3 is damaged by excessive force due to uneven force during use;

[0065] The limiting part 3 includes an anchor 32 in contact with the seabed, and the anchor 32 is connected to a floating member 31 through a connecting member, so that when the anchor 32 is subsequently recovered, the position of the anchor 32 can be accurately known through the floating member 31. The floating member 31 is connected to the anti-fouling curtain, so that the buoyancy of the anti-fouling curtain itself can be improved. This arrangement enables the anchor 32 to embed into the seabed by its own weight and the thrust of the water flow on the anti-fouling curtain when the anti-fouling curtain is impacted by the water flow. In this way, the range of movement of the anti-fouling curtain is limited to prevent the anti-fouling curtain from being washed away by the water flow when the water flow impact force is large;

[0066] A steel profile 4 is driven into the seabed below the anti-fouling curtain, and the steel profile 4 is connected to the anti-fouling curtain, so that the anti-fouling curtain can rely on the symmetrically arranged limit parts 3 and the steel profile 4 driven into the seabed to improve its own stability when impacted by water flow.

[0067] In an optional embodiment, the anti-fouling curtain includes a self-floating body 1 floating on the sea surface, a skirt 2 for blocking mud and sand is provided below the self-floating body 1, a counterweight 21 is provided below the skirt 2, and the counterweight 21 is evenly arranged along the hem of the skirt 2;

[0068] Furthermore, a side of the skirt 2 for intercepting sediment is provided with a reinforcement portion, and the reinforcement portion includes a first reinforcement belt 22 and a second reinforcement belt 23, wherein the first reinforcement belt 22 and the second reinforcement belt 23 are arranged alternately;

[0069] Optionally, the first reinforcement belt 22 and the second reinforcement belt 23 are arranged in a cross shape, such as Figure 3 shown.

[0070] In an optional embodiment, a warning light 11 is provided on the self-floating body 1. Figure 3 shown.

[0071] In an optional embodiment, the skirt 2 is made of water-permeable, aging-resistant, high-strength round wire filter cloth, and the strength of the filter cloth is ≥45-45KN / m.

[0072] In an optional embodiment, the anchor 32 is made of aging-resistant and corrosion-resistant materials.

[0073] The present invention is a positioning device for an anti-fouling curtain. By symmetrically arranging limiting parts on both sides of the anti-fouling curtain, and the limiting parts being directly connected to the seabed at one end away from the anti-fouling curtain, the anti-fouling curtain can be limited by the traction force of the two limiting parts after installation, and because the limiting parts are symmetrically arranged, the limiting parts can evenly distribute the force applied to the anti-fouling curtain, avoiding the problem of stress concentration, which may cause the limiting parts on one side to break; and the anti-fouling curtain is also provided with a steel section. Compared with traditional concrete blocks, the steel section is lighter, which reduces the transportation burden, reduces the fuel consumption and transportation cost of ships, and the steel section has high rigidity and strength and is vertically arranged in the seabed, so that it can provide more stable support. Compared with concrete blocks, steel parts are more solid under the impact of strong water currents and waves at sea, and can avoid the movement or displacement problem of traditional concrete blocks caused by uneven weight distribution or water flow impact, thereby improving the stability of the anti-fouling curtain; one end of the steel part is connected to the seabed and the other end is connected to the anti-fouling curtain, which not only determines the installation position of the anti-fouling curtain, but also has a traction effect on the anti-fouling curtain. The setting of the steel part can effectively disperse the water flow impact force on the anti-fouling curtain; at the same time, the steel part cooperates with the symmetrically arranged limiting parts, which can effectively distribute the force on the anti-fouling curtain to the steel part and the limiting part, thereby improving the stability of the anti-fouling curtain and avoiding the displacement of the anti-fouling curtain after being impacted; the present invention improves the stability of the anti-fouling curtain in seawater by arranging the limiting parts on the anti-fouling curtain, and also lays steel parts on the seabed to position the anti-fouling curtain to prevent the anti-fouling curtain from being displaced, and the anti-fouling curtain is fixed by replacing the traditional concrete blocks with steel parts, so that the transportation risk of the ship during transportation is reduced.

[0074] Example 2

[0075] This embodiment is the construction method of embodiment 1. In this method, the steel profile 4 is clamped by an elastic clamp 61. The elastic clamp 61 includes a mounting cavity 611, and the mounting cavity 611 is sleeved on the outside of the steel profile 4. The mounting cavity 611 is connected to the pressing device by a movable connection. One end of the pressing device abuts against the steel profile 4, and the other end is located outside the mounting cavity 611.

[0076] The pressing device includes a pressing plate 614, one side of which abuts against the steel member 4, and the other side of which is provided with a plurality of screws 615. A guide column 613 is provided between two adjacent screws 615 to provide structural stability. The pressing device also includes a force-bearing plate 612, which is movably connected to the screws 615 and the guide columns 613 to ensure that the force-bearing plate 612 can move freely.

[0077] A spring is sleeved on the outside of the guide column 613, one end of the spring is connected to the lower pressure plate 614, and the other end is connected to the force plate 612. A nut is provided on the top of the screw rod 615, and the bottom of the nut abuts against the top of the force plate 612. By tightening the nut, the force plate 612 can be driven to move toward the lower pressure plate 614, thereby compressing the spring.

[0078] The function of the spring is to control the pressure exerted by the lower pressure plate 614 on the steel member 4, so as to ensure that the steel member 4 is always subjected to a stable clamping force when the nut is adjusted. Figure 6 to Figure 7 shown.

[0079] like Figure 4 and Figure 5 The anti-fouling curtain construction method shown includes a positioning device for an anti-fouling curtain in Example 1, and the construction method includes the following steps:

[0080] S1: Before construction, the construction site environment is surveyed. The survey information includes the water level, water flow velocity and water flow direction at the construction site;

[0081] S2: Determine the layout plan of the anti-pollution curtains based on the exploration results. The plan includes the number of anti-pollution curtains, the length of the anti-pollution curtains, the depth of the anti-pollution curtains, and the spacing between adjacent anti-pollution curtains;

[0082] S3: After the plan is determined, the steel sheet pile driver is fixed by a flat boat to drive the steel member 4 at the location where the anti-fouling curtain needs to be arranged;

[0083] S4: After the steel member 4 is driven to a specified depth, the clamping force of the elastic clamp 61 on the steel member 4 is smaller than the friction between the steel member 4 and the seabed. At this time, the steel sheet pile driver is started to release the connection between the elastic clamp 61 and the steel member 4.

[0084] Specifically, after the steel profile 4 is embedded in the seabed, when the sum of the deadweight of the steel profile 4 and the friction between the steel profile 4 and the seabed exceeds the clamping force applied by the elastic clamp 61 to the steel profile 4, the steel sheet pile driver operates the piling part 5 to apply an upward pulling force to the steel profile 4. At this time, the steel profile 4 will overcome the clamping effect of the elastic clamp 61, thereby separating from the clamp, completing the clamping release process;

[0085] S5, transport the pre-assembled anti-fouling curtain to the construction site for installation. Since the steel part 4 has been accurately positioned, the installation process of the anti-fouling curtain becomes smoother, reducing the time for on-site adjustment and repeated construction;

[0086] S6: Inspect and accept the installed anti-fouling curtain and complete the construction of the anti-fouling curtain.

[0087] In an optional implementation manner, when the mooring force between the limiting portion on the anti-fouling curtain and the steel section is greater than the impact force of the water flow on the anti-fouling curtain, the acceptance is met.

[0088] In an optional implementation manner, the method for laying the medium-sized steel member 4 in step S3 is:

[0089] The first step is to use GPS and other positioning systems to accurately reach the designated piling position. After the steel sheet pile driver reaches the designated position, it inserts the steel member 4 into the seabed and initially fixes the steel member 4 at the driving position to ensure the accuracy and stability of subsequent piling operations.

[0090] Step 2: After the steel member 4 is inserted into the seabed, the piling unit 5 continuously tamps the auxiliary rod 6 connected to the steel member, and transmits the tamping force to the elastic clamp 61 at the upper end of the steel member 4 through the auxiliary rod 6, and then transmits the tamping force to the steel member 4 through the elastic clamp 61;

[0091] In the third step, the steel section 4 is embedded downward into the seabed under force. As the embedding depth of the steel section 4 increases, sufficient friction is generated between the steel section 4 and the surrounding soil to ensure that the steel section 4 remains stable during subsequent construction.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
