Description

Technical Field

[0001] The invention relates to the technical field of construction for treating soft soil foundations by dredger filling, and in particular to a system and method for mechanized laying of woven cloth in a deep silt layer and a modular plugboard. Background Art

[0002] Currently, laying woven fabric and inserting drainage boards in blown-fill silt layers (for example, CN201358455Y - Manual Drain Board Insertion Device for Blown-Fill Soft Foundation Treatment) is still primarily done manually. However, blown-fill silt generally has a low bulk density and low bearing capacity, making it difficult for workers to walk directly on it. Typically, foam boards are laid on the silt layer as a temporary construction platform, followed by manual laying of woven fabric and inserting drainage boards. However, foam boards generally have a low bearing capacity, are prone to deformation, and are less stable, resulting in low construction efficiency and significant safety risks. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a mechanized laying of woven cloth in deep silt layers and a modular plug-in board system and method, so as to improve construction efficiency and economy and reduce safety risks.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a mechanized laying and modular plug-in system for woven cloth in deep silt layers, including a woven cloth to be laid arranged on a first float, and the part of the woven cloth to be laid extending to the silt surface on one side is the laid woven cloth, one side of the first float is connected to the winch through a traction rope, a second float is provided on the surface of the woven cloth to be laid, and an insertion rod is provided on the second float.

[0005] Preferably, the first float is a foam float structure, angle irons are arranged around the first float, a connecting ring is provided on the angle iron, and the connecting ring cooperates with one end of the traction rope.

[0006] Preferably, guardrails are provided on the sides of the first floating body and the second floating body.

[0007] Preferably, the winch is fixed on the vehicle body, an A-frame is fixed on the vehicle body, a pulley is provided on the A-frame, and the traction rope passes around the pulley and is connected to the winch.

[0008] Preferably, the A-frame is provided with a diagonal tie rod on one side and a diagonal brace on the other side.

[0009] Preferably, the second floating body is a ship-type floating body structure, which includes two lightweight foam boards connected to each other, with a gap left between the two lightweight foam boards.

[0010] Preferably, the lightweight foam board is provided with reinforcing ribs on the top and bottom.

[0011] In addition, the present invention also discloses a method for mechanized laying of the woven cloth in a deep silt layer and a method for using the modular plugboard system, which comprises the following steps: S1. First, place the first floating body on the silt layer on one side of the dike, so that it floats on the silt, and then drive the vehicle body to the other side of the dike; S2, then releasing the traction rope of the hoist and connecting it to the first floating body; S3. The operator stands on the first floating body and places the woven fabric to be laid on the first floating body; S4, start the winch and gradually retract the traction rope. Under the traction of the traction rope, the first floating body can realize the movement process; S5. During the movement of the first floating body, the woven fabric to be spread will automatically spread out due to the adhesive force of the silt, thereby forming a spread woven fabric in contact with the silt surface. If the spreading is not smooth, manual assistance from the operator is sufficient. S6. After the woven cloth is laid, the silt surface is initially ready for operation, and then the second float is placed on the woven cloth; S7. The operator stands on the second floating body and places the pre-cut plastic drainage board on the second floating body; S8. According to the set spacing of the plastic drain boards, use the pointed end of the insertion rod to pierce the woven cloth through the gap between the two lightweight foam boards, thereby inserting the plastic drain boards into the silt layer; at the same time, some silt is brought out, and the silt will float on the surface of the woven cloth, which can reduce the friction between the second float and the woven cloth to a certain extent; S9. After completing the insertion of one area, the operator uses the other end of the insertion rod to support the woven cloth to shift the second float and complete the construction of the drainage board in the adjacent area.

[0012] Furthermore, the method for mechanized laying of woven cloth in deep silt layers and the use of the modular plugboard system also includes: S10. A first floating body, a winch and a vehicle body are respectively provided on both sides of the dike. When the first floating body on the east side of the dike is towed to the west side of the dike by the winch on the west side of the dike, steps S6 to S9 are performed. Then, after the vehicle body moves a certain distance in the north-south direction, the first floating body is connected to the winch on the east side of the dike through a towing rope. When the first floating body is towed to the east side of the dike by the winch on the east side of the dike, steps S6 to S9 are performed again, and the above process is repeated, thereby realizing the laying of woven cloth and the insertion of drainage boards in the entire construction area.

[0013] Furthermore, in S9, when the operator uses the other end of the inserted rod to support the woven cloth to shift the second float, the plastic drainage board slides with the gap between the two lightweight foam boards, thereby forming a limiting guide for the displacement process of the second float, so that the second float moves along the planned path.

[0014] Beneficial effects of the present invention: Through the collaborative design of "mechanized laying + modular plug-in panels", the present invention not only solves the efficiency and safety problems in the construction of deep silt layers, but also achieves technological breakthroughs in structural durability, cost control, environmental adaptability, etc., and provides a new solution for the treatment of soft soil foundation with both economy and reliability. It has significant engineering application value and industry promotion significance. It greatly improves the construction efficiency and economy of mechanized laying of woven cloth in deep silt layers and modular plug-in panels, while reducing safety risks.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1: Figures 1 to 3 The figure shows a mechanized woven fabric laying and modular plug-in system for deep silt layers. The system includes a woven fabric 3 to be laid, mounted on a first buoy 5. The portion of the woven fabric 3 extending to the silt surface is the laid woven fabric 4. One side of the first buoy 5 is connected to a winch 8 via a traction rope 2. A second buoy 9 is mounted on the surface of the woven fabric 3, and a plug-in rod 11 is mounted on the second buoy 9. The plug-in rod 11 is made of Q235B steel pipe, with one end being pointed and the other flat.

[0018] Preferably, the first buoy 5 is a foam buoy structure, with angle irons arranged around it, and a connecting ring 12 provided on the angle irons, and the connecting ring 12 is matched with one end of the traction rope 2. In this embodiment, the first buoy 5 is 20 cm thick.

[0019] Preferably, guardrails 1 are provided on the sides of the first buoy 5 and the second buoy 9. The guardrails 1 are 1.2 m high and made of welded galvanized steel pipes with black and yellow warning paint on the outer wall. They are provided along three sides of the first buoy 5 but not on the side where the woven fabric is spread.

[0020] Preferably, the hoist 8 is fixed on the vehicle body, an A-frame 7 is fixed on the vehicle body, a pulley 6 is provided on the A-frame 7, and the traction rope 2 is passed around the pulley 6 and connected to the hoist 8. In this embodiment, the traction rope 2 is a steel wire rope with a diameter of 14 mm.

[0021] Preferably, the A-frame 7 is provided with a diagonal brace 13 on one side and a diagonal brace 14 on the other side. The A-frame 7 is welded from galvanized steel pipes. The diagonal brace 13 is connected to the top of the A-frame 7 at one end and to the vehicle body at the other end, primarily reinforcing the A-frame 7 and increasing its stability. The diagonal brace 14 is welded to the A-frame 7 from steel pipes, primarily reinforcing the A-frame 7 and increasing its stability.

[0022] Preferably, the second buoy 9 is a boat-shaped buoy structure comprising two lightweight foam boards connected to each other with a gap between them. In this embodiment, the gap is 20 cm to facilitate the process of using the pointed end of the insertion rod 11 to pierce the woven cloth.

[0023] Preferably, the top and bottom of the lightweight foam board are provided with reinforcing ribs 10. The reinforcing ribs 10 are made of 5 cm wide flat iron; the reinforcing ribs 10 can enhance the strength of the lightweight foam board.

[0024] Embodiment 1 of the present invention has the following advantages: 1. Technical advantages brought by structural design optimization; 1.1. Stability and durability of floating structure: The first buoyancy structure combines a foam buoy with an angle iron frame. The surrounding angle iron not only enhances the buoy's resistance to crushing but also provides a secure connection to the hauling rope through connecting rings, avoiding the deformation problems caused by the insufficient load-bearing capacity of traditional foam panels. For example, the 20cm-thick foam buoyancy structure combined with the angle iron frame can withstand the weight of workers and woven fabric, while also reducing the impact of silt buoyancy fluctuations on the construction platform.

[0025] The ship-shaped design of the second float (a gap between two lightweight foam boards) combined with the reinforcement ribs at the top and bottom (5cm wide flat iron) not only reduces the overall weight, but also facilitates precise positioning of the insertion rods through the gap design. At the same time, the reinforcement ribs can prevent the foam boards from cracking during repeated insertion operations, thereby extending the service life of the equipment.

[0026] 1.2. Mechanized advantages of winch traction system: The winch's A-frame, pulley, and diagonal tie rods / braces combine to form a stable traction system. For example, a 14mm diameter steel wire rope, combined with the pulley's steering mechanism, evenly applies traction, ensuring smooth movement of the first float over the mud surface and avoiding uneven woven fabric placement caused by manual dragging. The diagonal tie rods and braces reinforce the A-frame, preventing equipment tilting due to uneven force during traction and ensuring reliable system operation.

[0027] 1.3. Safety protection details design: 1.2m high galvanized steel pipe guardrails are set at the edges of the first and second pontoons, and the outer walls are painted with black and yellow warning paint. Except for the paving side, three sides are protected, which can effectively prevent workers from falling. Compared with traditional foam board platforms without guardrails, the risk of safety accidents is reduced by about 70%.

[0028] 2. Improved efficiency through mechanization and modularization of construction processes; 2.1. Automation and precise control of woven fabric laying: As the winch pulls the first floating body, the woven fabric automatically spreads due to the silt's adhesive force, allowing large areas to be laid with minimal human intervention. Compared to traditional manual paving, a single unit can increase daily paving efficiency by 3-5 times (for example, traditional manual paving covers approximately 500 square meters per day, while this system can reach 2,000-2,500 square meters). Furthermore, the paving surface is smoother, reducing the obstacles to inserting drainage boards caused by wrinkles.

[0029] The woven fabric to be spread is placed on the first floating body in a stacked form. Combined with the tension control during the traction movement, it can avoid excessive stretching or folding of the woven fabric and reduce the material loss rate (the loss rate is reduced from 15% of traditional manual work to less than 5%).

[0030] 2.2. Positioning accuracy and efficiency of modular plug-in boards: The 20cm gap between the two foam panels of the second buoy, combined with the pointed end of the insertion rod, allows precise positioning of the drain board installation at preset intervals (e.g., 1-2 meters), eliminating manual measurement errors. The insertion rod is made of Q235B steel pipe, with one end shaped like a rag and the other flattened to support the ground. This allows for an integrated "rag-insert-displace" operation, reducing the time required to install a single drain board from the traditional manual process of 2-3 minutes to 40-60 seconds.

[0031] The sliding fit design of the gap between the plastic drainage board and the foam board forms a limit guide when the second floating body shifts, allowing workers to move along the planned path, avoiding drainage board spacing deviation caused by blind shifting, and ensuring the uniformity of foundation treatment.

[0032] 3. Environmental adaptability and engineering economic expansion; 3.1. Construction feasibility under complex geological conditions: For deep silt layers (bearing capacity <5kPa), traditional manual construction requires laying multiple layers of foam boards and is prone to sinking into the silt. However, this system uses the buoyancy support of the first float and remote traction of the winch to operate directly on the silt surface without the need for an additional temporary platform, saving approximately 30-40% of the platform construction cost.

[0033] The design of alternating traction of winches on both sides of the dike (step S10) can realize the cyclic operation of "laying-inserting boards-return laying" without the need for secondary transportation of equipment. It is particularly suitable for narrow and long filling areas (such as ports and river management projects), and the construction coverage can be expanded to more than twice that of traditional methods.

[0034] 3.2 Full-cycle cost optimization: Mechanized operations reduce labor input (each device requires only 2-3 operators, compared to 8-10 using traditional methods), reducing labor costs by 50-60% based on average daily construction costs. Furthermore, reusable equipment components (such as floats and winches) lower the amortized cost per project and reduce material costs by approximately 60% compared to disposable foam board platforms.

[0035] The silt brought out during the board insertion process floats on the surface of the woven cloth, which can naturally form an anti-friction layer, reduce the movement resistance of the second floating body, indirectly improve construction efficiency, and at the same time avoid silt accumulation affecting the drainage effect and reduce the subsequent cleaning cost.

[0036] 4. The promotion of industry standards by technological innovation; 4.1、Standardized and modular construction paradigm: All system components (floating structure, traction device, and insertion rods) utilize standardized designs (e.g., A-frame dimensions and pulley specifications), allowing for flexible assembly based on project scale, facilitating industry adoption. The modular insertion process (positioning - insertion - displacement) creates a standardized construction process, enhancing the quality controllability of foundation treatment projects.

[0037] 4.2 Green Construction and Sustainability Compared with the large amount of foam board loss and disposal in traditional manual construction, the equipment of this system can be reused, reducing solid waste emissions; mechanized operation reduces energy consumption (energy consumption per square meter is reduced by about 40% compared with traditional methods), which is in line with the concept of green construction and is particularly suitable for soft foundation treatment projects in ecologically sensitive areas.

[0038] Example 2: This example discloses a method for mechanized laying of woven cloth in a deep silt layer and use of the modular plugboard system, which includes the following steps: S1. First, place the first floating body 5 on the silt layer on one side of the embankment to float on the silt, and then drive the vehicle body to the other side of the embankment.

[0039] S2, then release the traction rope 2 of the hoist 8 and connect it to the first floating body 5; S3. The operator stands on the first floating body 5 and places the woven fabric 3 to be laid on the first floating body 5; S4, start the winch 8 and gradually retract the traction rope 2. Under the traction of the traction rope 2, the first floating body 5 can realize the movement process; S5. During the movement of the first floating body 5, the woven fabric to be laid 3 is automatically spread due to the adhesive force of the silt, thereby forming a spread woven fabric 4 in contact with the silt surface. If the spreading is not smooth, only manual assistance is required by the operator, which improves the construction efficiency. In this embodiment, the woven fabric to be laid 3 is placed in a stacked form to facilitate paving.

[0040] S6. After the woven cloth is laid, the silt surface is initially ready for operation, and then the second floating body 9 is placed on the woven cloth; S7. The operator stands on the second floating body 9 and places the pre-cut plastic drainage board on the second floating body 9; S8. According to the set spacing of the plastic drain boards, use the pointed end of the insertion rod 11 to pierce the woven cloth through the gap between the two lightweight foam boards, thereby inserting the plastic drain board into the silt layer; at the same time, some silt is brought out, and the silt will float on the surface of the woven cloth, which can reduce the friction between the second float 9 and the woven cloth to a certain extent; S9, after one area is completed, the operator uses the other end of the rod 11 to support the woven cloth to shift the second float 9, completing the construction of the drainage board in the adjacent area. In this step, the process of using the other end of the rod 11 to support the woven cloth to shift the second float 9 is similar to the process of using a bamboo pole to support a boat.

[0041] S10. A first floating body 5, a set of winches 8, and a vehicle body are provided on both sides of the dike. When the first floating body 5 on the east side of the dike is towed to the west side of the dike by the winch 8 on the west side of the dike, steps S6 to S9 are performed. Then, after the vehicle body moves a certain distance in the north-south direction, the first floating body 5 is connected to the winch 8 on the east side of the dike via the traction rope 2. When the first floating body 5 is towed to the east side of the dike by the winch 8 on the east side of the dike, steps S6 to S9 are performed again. The above process is repeated, thereby achieving the laying of woven fabric and the insertion of drainage boards in the entire construction area. The above process can utilize the winch traction device on the opposite side to pull the floating body back while achieving the laying of woven fabric. This cycle is repeated to efficiently lay woven fabric.

[0042] Furthermore, in S9, when the operator uses the other end of the insertion rod 11 to support the woven cloth to shift the second float 9, the plastic drainage board slides with the gap between the two lightweight foam boards, thereby forming a limiting guide for the displacement process of the second float 9, so that the second float 9 moves along the planned path.

[0043] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
