Description

Technical Field

[0001] This invention relates to the field of water-related engineering, and in particular to a positioning device for a dirt-proof curtain and its construction method. Background Technology

[0002] During dredging projects, the processes of dredging, transporting, and filling overflows often disturb and diffuse existing contaminated sediment layers and uncontaminated native soil particles. This disturbance can cause a rapid increase in the concentration of suspended solids in the water, resulting in varying degrees of pollution to the surrounding waters. Furthermore, due to the complexity and wide distribution of dredging operations, the pollution range at sea is extensive, posing even greater challenges to the environment. In particular, when sediment layers containing toxic or hazardous substances are disturbed, the diffused pollutants can seriously threaten the marine ecosystem and water quality safety.

[0003] In current engineering practice, antifouling curtains are typically installed around the construction area to prevent the spread of sediment. However, the effectiveness of antifouling curtains is limited in different construction environments. When the construction site is far from the coast and in waters with large tidal ranges and high waves, the fixation and stability of the antifouling curtains become challenging. Under these harsh marine conditions, antifouling curtains are often difficult to secure effectively and are easily impacted by strong currents, waves, and tides. These external forces can cause damage or displacement of the antifouling curtains, resulting in the loss of their antifouling function and the spread of sediment and pollutants into the surrounding waters. Moreover, after the antifouling curtains fail, the spread may accelerate further, expanding the scope of pollution and increasing the difficulty of control. This situation is particularly common in offshore dredging projects, posing additional environmental management challenges to construction companies.

[0004] Furthermore, traditionally, construction companies typically use concrete blocks to secure antifouling curtains or other equipment. However, this practice has several significant drawbacks during maritime transport. First, the weight of concrete blocks increases the overall weight of the vessel, thereby raising fuel consumption and transportation costs. Second, uneven weight distribution of the concrete blocks can affect the vessel's stability, especially in rough seas, potentially leading to increased rolling and posing safety risks. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem that traditional antifouling curtains in the prior art are fixed by concrete blocks, which increases the transportation risk when transporting concrete blocks by ships due to their large weight and difficulty in fixing them during transportation. Therefore, this invention provides a positioning device for antifouling curtains and also proposes a construction method for antifouling curtains.

[0006] In a first aspect, the present invention provides a positioning device for an antifouling curtain, comprising a pair of limiting parts, one end of which is connected to the antifouling curtain and the other end of which is connected to the seabed; and further comprising a steel member located in the area below the antifouling curtain, one end of which is connected to the seabed and the other end of which is connected to the antifouling curtain, and the steel member being vertically disposed within the seabed.

[0007] This invention relates to a positioning device for an antifouling curtain. By symmetrically arranging limiting parts on both sides of the antifouling curtain, with the end of the limiting part furthest from the curtain directly connected to the seabed, the antifouling curtain can be limited by the traction force of the two limiting parts after installation. Furthermore, because the limiting parts are symmetrically arranged, the force applied to the antifouling curtain is evenly distributed, avoiding stress concentration and preventing breakage of the limiting part on one side. The antifouling curtain also incorporates steel components, which are lighter than traditional concrete blocks, reducing transportation burden, lowering ship fuel consumption and transportation costs. Moreover, the steel components have high rigidity and strength, and their vertical arrangement within the seabed provides more stable support. Compared to concrete blocks, steel components are more robust against strong currents and waves at sea, avoiding the movement or displacement problems caused by uneven weight distribution or water flow impacts of traditional concrete blocks, thus improving the stability of the antifouling curtain. One end of the steel component connects to the seabed, and the other end connects to the antifouling curtain, determining its installation position and providing traction. The steel component effectively disperses the impact force of the water flow on the antifouling curtain. Simultaneously, the steel component, in conjunction with symmetrically arranged limiting parts, effectively distributes the force on the antifouling curtain across the steel component and limiting parts, improving its stability and preventing displacement after impact. This invention improves the stability of the antifouling curtain in seawater by setting limiting parts on it, and uses steel components on the seabed to position the antifouling curtain and prevent displacement. Furthermore, replacing traditional concrete blocks with steel components for fixing the antifouling curtain reduces transportation risks during ship transport.

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

[0009] By incorporating a self-floating body, the skirt can float on the sea surface; a counterweight is also provided at the lower end of the skirt to ensure that the skirt can unfold in the seawater and achieve an interception effect.

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

[0011] This design is to prevent the entire self-floating body from being pulled into the water by the counterweight due to excessive weight, which would cause the anti-fouling curtain to fail.

[0012] Preferably, the limiting part includes a floating member connected to the self-floating body part; the limiting part 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 of which is connected to the self-floating body part.

[0013] Connecting the anchor to the self-floating body via a floating component serves two purposes: firstly, it allows for precise location of the anchor during later retrieval; secondly, connecting the floating component to the self-floating body increases the overall buoyancy of the antifouling curtain; and thirdly, the anchor allows the antifouling curtain to be fixed in place by its own weight after being impacted by water flow, thus improving the stability of the antifouling curtain.

[0014] Preferably, the skirt body is provided with a reinforcing part, and the reinforcing part is arranged in the same direction as the water flow direction.

[0015] Preferably, the reinforcing part includes a first reinforcing strip and a second reinforcing strip, and the first reinforcing strip and the second reinforcing strip are arranged alternately.

[0016] By setting a first reinforcing band and a second reinforcing band on the skirt, and staggering the first reinforcing band and the second reinforcing band, the skirt can effectively distribute the force after being impacted by water flow, avoiding uneven force on different parts of the skirt, which could cause the skirt to flip over and reduce the interception efficiency of this anti-fouling curtain.

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

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

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

[0020] This improved the overall filtration efficiency of the anti-fouling curtain, effectively intercepting sediment.

[0021] Preferably, the anchor is made of aging-resistant and corrosion-resistant materials.

[0022] In a second aspect, the present invention provides a method for constructing a dirt curtain, including the aforementioned positioning device for a dirt curtain, and further including a sheet pile driver for constructing the dirt curtain, wherein the sheet pile driver is equipped with elastic clamps;

[0023] The construction method includes the following steps:

[0024] S1. Select the installation location of the steel profile;

[0025] S2. Use elastic clamps to hold the steel profile, and start the sheet pile machine at the driving position to drive the steel profile;

[0026] S3. After the steel section is driven and fixed, start the sheet pile machine to release the connection between the elastic clamp and the steel section;

[0027] S4. Transport the anti-fouling curtain to the steel component for installation;

[0028] S5. Construction completed.

[0029] This invention discloses a method for constructing an antifouling curtain. The antifouling curtain's stability is enhanced through a limiting part and steel components. Furthermore, preliminary surveying and scheme development ensure that the curtain's specifications and layout match the site environment, effectively avoiding environmental compatibility issues and improving antifouling performance. A steel sheet pile driver is used to install the steel components, ensuring accurate fixing at the designated location and enabling rapid installation of the antifouling curtain. Transportation and installation of the antifouling curtain after the steel components are fixed optimize the construction process, reduce on-site adjustment time, and improve overall installation efficiency. Elastic clamps are used to hold and drive the steel components. After installation, the friction between the steel components and the seabed allows the elastic clamps to automatically disengage after pile driving, eliminating the need for manual operation, simplifying the construction process, and improving efficiency. Since the connection between the steel components and the elastic clamps relies on the elastic components, the clamps can smoothly and automatically detach after pile driving, reducing safety risks during manual operation.

[0030] Preferably, the elastic clamp includes a mounting cavity, which is sleeved on the outside of the steel profile. A pressing device is movably connected to the mounting cavity, with one end of the pressing device abutting against the steel profile and the other end located outside the mounting cavity.

[0031] Preferably, the pressing device includes a pressing plate, one side of which abuts against the steel profile and the other side is provided with a plurality of screws, and a guide post is provided between two adjacent screws. The pressing device includes a force-bearing plate, which is movably connected to the screws and the guide post respectively.

[0032] A spring is sleeved on the outside of the guide post, with one end of the spring connected to the lower pressure plate and the other end connected to the force plate.

[0033] The top of the screw is provided with a nut, the bottom of the nut abuts against the top of the force plate, and the nut is used to drive the force plate to move toward the lower pressure plate;

[0034] The spring is used to control the force applied by the lower pressure plate to the steel profile.

[0035] Preferably, the connection steps between the elastic clamp and the steel profile are as follows:

[0036] Step 1: The operator loosens the nut to relax the spring on the guide post;

[0037] The second step is for the operator to fit the steel profile into the mounting cavity and then abut the steel profile against the lower pressure plate.

[0038] Third step: Tighten the nut, which will cause the force plate to press down. During the pressing down of the force plate, the spring connected to it will also press down.

[0039] Fourth step: As the nut is tightened further, the spring is compressed, which at the same time drives the lower pressure plate to apply downward pressure to the steel part, so that the steel part fits tightly against the installation cavity and the lower pressure plate, ensuring that the steel part is firmly fixed.

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

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

[0042] Preferably, in steps S1 and S2, the water level and flow information of the 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 with the elastic clamp and releasing the connection between the steel profile and the elastic clamp after installation is as follows:

[0044] The operator slowly inserts the steel component into the seabed, ensuring that the bottom of the component is fully embedded. As the component penetrates deeper, the friction between the seabed and the component increases until it reaches a critical value. When the friction exceeds the clamping force of the elastic clamp, the clamping force can no longer hold the component in place. When the friction exceeds the clamping force, the component will naturally separate from the elastic clamp, completing the disconnection process.

[0045] By utilizing the friction between the steel profile and the seabed, the connection of the elastic clamp can be automatically released after piling is completed, eliminating the need for additional manual operation, simplifying the construction process and improving efficiency. Since the connection between the steel profile and the elastic clamp relies on the action of the elastic component, the clamp can be smoothly and automatically released after piling is completed, reducing the safety risks during manual operation.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0047] 1. This invention relates to a positioning device for an antifouling curtain. By symmetrically arranging limiting parts on both sides of the antifouling curtain, with the end of the limiting part furthest from the antifouling curtain directly connected to the seabed, the antifouling curtain can be limited by the traction force of the two limiting parts after installation. Furthermore, because the limiting parts are symmetrically arranged, the force applied to the antifouling curtain can be evenly distributed, avoiding stress concentration and preventing breakage of the limiting part on one side. The antifouling curtain also includes steel components, which are lighter than traditional concrete blocks, reducing transportation burden, lowering ship fuel consumption and transportation costs. Moreover, the steel components have high rigidity and strength, and their vertical arrangement within the seabed provides more stable support. Compared to concrete blocks, steel components are more robust against strong currents and waves at sea, avoiding the movement or displacement problems caused by uneven weight distribution or water flow impacts of traditional concrete blocks, thus improving the stability of the antifouling curtain. One end of the steel component connects to the seabed, and the other end connects to the antifouling curtain, determining its installation position and providing traction. The steel component effectively disperses the impact force of the water flow on the antifouling curtain. Simultaneously, the steel component, in conjunction with symmetrically arranged limiting parts, effectively distributes the force on the antifouling curtain across the steel component and limiting parts, improving its stability and preventing displacement after impact. This invention improves the stability of the antifouling curtain in seawater by setting limiting parts on it, and uses steel components on the seabed to position the antifouling curtain and prevent displacement. Furthermore, replacing traditional concrete blocks with steel components for fixing the antifouling curtain reduces transportation risks during ship transport.

Detailed Implementation

[0057] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0058] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0059] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0060] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0061] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0062] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0063] Example 1

[0064] like Figure 1 and Figure 2As shown, a positioning device for an antifouling curtain includes an antifouling curtain placed in the sea. The antifouling curtain is provided with at least two limiting parts 3, and the limiting parts 3 are symmetrically arranged about the antifouling curtain as an axis of symmetry. One end of each limiting part 3 is connected to the antifouling curtain, and the other end of the limiting part 3 is connected to the seabed. The advantage of this arrangement is that when the antifouling curtain is working in the seawater, it is impacted by the water flow. The impact force on the antifouling curtain can be evenly distributed by the two symmetrically arranged limiting parts 3, which effectively ensures the structural stability of the antifouling curtain. Furthermore, since the limiting parts 3 are symmetrically designed, the situation where one of the limiting parts 3 is damaged due to excessive force due to uneven force distribution will not occur during use.

[0065] The limiting part 3 includes an anchor 32 that contacts the seabed. The anchor 32 is connected to a floating part 31 via a connector. This allows the anchor 32 to be accurately located via the floating part 31 when it is retrieved. The floating part 31 is connected to the antifouling curtain, which increases the buoyancy of the antifouling curtain itself. This design allows the anchor 32 to embed itself into the seabed by its own weight and the thrust of the water flow when the antifouling curtain is impacted by the water flow. This restricts the range of motion of the antifouling curtain and prevents it from being washed away by the water flow when the impact force is large.

[0066] A steel component 4 is installed in the seabed below the antifouling curtain. The steel component 4 is connected to the antifouling curtain, so that the antifouling curtain can improve its stability when it is impacted by water flow by relying on the symmetrically arranged limiting parts 3 and the steel component 4 installed in the seabed.

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

[0068] Furthermore, the side of the skirt 2 used for intercepting mud and sand is provided with a reinforcing part, which includes a first reinforcing strip 22 and a second reinforcing strip 23, wherein the first reinforcing strip 22 and the second reinforcing strip 23 are arranged alternately;

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

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

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

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

[0073] This invention relates to a positioning device for an antifouling curtain. By symmetrically arranging limiting parts on both sides of the antifouling curtain, with the end of the limiting part furthest from the curtain directly connected to the seabed, the antifouling curtain can be limited by the traction force of the two limiting parts after installation. Furthermore, because the limiting parts are symmetrically arranged, the force applied to the antifouling curtain is evenly distributed, avoiding stress concentration and preventing breakage of the limiting part on one side. The antifouling curtain also incorporates steel components, which are lighter than traditional concrete blocks, reducing transportation burden, lowering ship fuel consumption and transportation costs. Moreover, the steel components have high rigidity and strength, and their vertical arrangement within the seabed provides more stable support. Compared to concrete blocks, steel components are more robust against strong currents and waves at sea, avoiding the movement or displacement problems caused by uneven weight distribution or water flow impacts of traditional concrete blocks, thus improving the stability of the antifouling curtain. One end of the steel component connects to the seabed, and the other end connects to the antifouling curtain, determining its installation position and providing traction. The steel component effectively disperses the impact force of the water flow on the antifouling curtain. Simultaneously, the steel component, in conjunction with symmetrically arranged limiting parts, effectively distributes the force on the antifouling curtain across the steel component and limiting parts, improving its stability and preventing displacement after impact. This invention improves the stability of the antifouling curtain in seawater by setting limiting parts on it, and uses steel components on the seabed to position the antifouling curtain and prevent displacement. Furthermore, replacing traditional concrete blocks with steel components for fixing the antifouling curtain reduces transportation risks during ship transport.

[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, which is sleeved on the outside of the steel profile 4. The mounting cavity 611 is connected to a pressing device through 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 profile 4, and the other side is provided with several screws 615. A guide post 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 post 613 to ensure that the force-bearing plate 612 can move freely.

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

[0078] The function of the spring is to control the pressure applied by the lower pressure plate 614 to the steel profile 4, ensuring that the steel profile 4 is always subjected to a stable clamping force when the nut is adjusted. Figures 6 to 7 As shown.

[0079] like Figure 4 and Figure 5 The method for constructing a dirt-proof curtain, as shown in Example 1, includes a positioning device for the dirt-proof curtain. The construction method includes the following steps:

[0080] S1: Before construction, conduct an environmental survey of the construction site. The survey information includes the water level, water flow velocity, and water flow direction at the construction site.

[0081] S2: Based on the exploration results, determine the layout plan of the anti-fouling curtains. The plan includes the number of anti-fouling curtains, the length of the anti-fouling curtains, the depth of the anti-fouling curtains, and the spacing between adjacent anti-fouling curtains.

[0082] S3: After the plan is determined, the steel sheet pile driver is fixed on a flatboat to install the steel section 4 at the location where the anti-fouling curtain needs to be placed;

[0083] S4: After the steel section 4 is driven to the specified depth, the clamping force of the elastic clamp 61 on the steel section 4 is less than the friction force between the steel section 4 and the seabed. At this time, the steel sheet pile machine is started to disconnect the connection between the elastic clamp 61 and the steel section 4.

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

[0085] S5. Transport the pre-assembled anti-fouling curtain to the construction site for installation. Since the steel component 4 is already accurately positioned, the installation process of the anti-fouling curtain becomes smoother, reducing the time spent on on-site adjustments and repeated construction.

[0086] S6: Inspect the installed anti-fouling curtains to complete the construction of the anti-fouling curtains.

[0087] In an optional embodiment, the acceptance is met when the retaining force between the limiting part on the anti-fouling curtain and the steel component is greater than the water flow impact force on the anti-fouling curtain.

[0088] In an optional implementation, the method for installing the steel component 4 in step S3 is as follows:

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

[0090] The second step is that after the steel section 4 is inserted into the seabed, the pile driving part 5 continuously tamps the auxiliary rod 6 connected to the steel section. The tamping force is transmitted to the elastic clamp 61 at the upper end of the steel section 4 through the auxiliary rod 6, and then the tamping force is transmitted to the steel section 4 through the elastic clamp 61.

[0091] The third step is to embed the steel component 4 downwards into the seabed under force. As the embedment depth of the steel component 4 increases, sufficient friction is generated between the steel component 4 and the surrounding soil to ensure that the steel component 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 within the protection scope of the present invention.

The steel section (4) is vertically arranged in the seabed. The antifouling curtain includes a self-floating body (1) and a skirt (2) at its lower end. A counterweight (21) is provided at the lower end of the skirt (2). The limiting part (3) includes a floating part (31) connected to the self-floating body (1). The limiting part (3) also includes an anchor (32) with a connector (33) connected to one end. One end of the connector (33) is connected to the anchor (32) and the other end is connected to the self-floating body (1). The skirt (2) is provided with a reinforcing part. The reinforcing part is arranged in the same direction as the water flow direction. The reinforcing part includes a first reinforcing band (22) and a second reinforcing band (23). The first reinforcing band (22) and the second reinforcing band (23) are arranged alternately. The steel section (4) is an I-beam. It also includes a sheet pile driver for the construction of anti-fouling curtains, the sheet pile driver being equipped with a flexible clamp (61). The construction method includes the following steps: S1. Before construction, conduct an environmental survey of the construction site. The survey information includes the water level, water flow velocity, and water flow direction at the construction site. S2. Based on the exploration results, determine the layout plan of the anti-fouling curtains. The plan includes the number of anti-fouling curtains, the length of the anti-fouling curtains, the depth of the anti-fouling curtains, and the spacing between adjacent anti-fouling curtains. S3. After the plan is determined, the steel sheet pile driver is fixed on a flatboat to install the steel section (4) at the location where the anti-fouling curtain needs to be arranged. S4. After the steel section (4) is driven to the specified depth, the clamping force of the elastic clamp (61) on the steel section (4) is less than the friction force between the steel section (4) and the seabed. At this time, the sheet pile machine is started to disconnect the connection between the elastic clamp (61) and the steel section (4). Specifically, after the steel section (4) is embedded in the seabed, when the sum of the self-weight of the steel section (4) and the friction force between the steel section (4) and the seabed exceeds the clamping force applied by the elastic clamp (61) on the steel section (4), the sheet pile machine applies an upward pulling force to the steel section (4). At this time, the steel section (4) will overcome the clamping effect of the elastic clamp (61) and thus separate from the clamp, completing the clamping release process. S5. Transport the pre-assembled anti-pollution curtain to the construction site for installation. Since the steel parts (4) have been accurately positioned, the installation process of the anti-pollution curtain becomes smoother, reducing the time for on-site adjustments and repeated construction. S6. Inspect the installed anti-fouling curtains to complete the construction of the anti-fouling curtains.
