Description

Technical Field

[0001] This invention relates to the field of construction technology for soft soil foundation treatment by hydraulic filling, and in particular to a mechanized laying system and method for laying woven fabric in a deep silt layer and for modular insertion of slabs. Background Art

[0002] Currently, the mainstream method for laying woven fabric and inserting drainage boards (e.g., CN201358455Y-Manual Drainage Board Device for Soft Soil Treatment of Dredged Silt) in dredged silt layers is still manual. However, dredged silt generally has low density and low bearing capacity, making it impossible for workers to walk or work directly on it. Typically, foam boards are laid on the silt layer as a temporary construction platform, followed by manual spreading of woven fabric and insertion of drainage boards. However, foam boards usually have low bearing capacity, are prone to deformation, and have poor stability. Furthermore, the construction efficiency is low, and the construction safety risks are extremely high. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a mechanized laying system and method for woven fabric in deep silt layers and modular insertion plates, thereby improving construction efficiency and economy and reducing safety risks.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a mechanized laying system for woven fabric in a deep silt layer and a modular insert plate system, including a woven fabric to be laid on a first float, a portion of the woven fabric to be laid extending to the silt surface on one side is a laid woven fabric, one side of the first float is connected to a winch by a traction rope, a second float is provided on the surface of the laid woven fabric, and an insert rod is provided on the second float.

[0005] Preferably, the first float is a foam float structure with angle irons around it, and a connecting ring is provided on the angle irons, which is engaged with one end of the traction rope.

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

[0007] Preferably, the winch is fixedly mounted on the vehicle body, and an A-frame is fixedly mounted on the vehicle body. A pulley is mounted on the A-frame, and the traction rope passes around the pulley and connects 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 float is a boat-shaped float structure, which includes two lightweight foam boards connected to each other, with a gap between the two lightweight foam boards.

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

[0011] In addition, the present invention also discloses a method for using the above-mentioned mechanized laying of woven fabric and modular insert system for deep silt layers, which includes the following steps:

[0012] S1. First, place the first float on the silt layer on one side of the dike, so that it floats on the silt, and then drive the vehicle to the other side of the dike.

[0013] S2. Then release the winch's traction rope and connect it to the first float.

[0014] S3. The operator stands on the first float and places the woven fabric to be laid on the first float;

[0015] S4. Start the winch and gradually retract the traction rope. Under the traction of the traction rope, the first float can move.

[0016] S5. During the movement of the first float, the woven fabric to be laid will automatically spread out due to the adhesion force of the silt, thus forming a laid woven fabric in contact with the silt surface. If the spreading is not smooth, the operator only needs to manually assist.

[0017] S6. After the woven fabric is laid, the surface of the silt will initially meet the working conditions, and then the second float will be placed on the woven fabric.

[0018] S7. The operator stands on the second float and places the pre-cut plastic drainage board on the second float at the same time.

[0019] S8. According to the set spacing of the plastic drainage boards, through the gap between the two lightweight foam boards, use the tip of the insertion rod to puncture the woven fabric, thereby inserting the plastic drainage 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 fabric, which can reduce the friction between the second float and the woven fabric to a certain extent.

[0020] S9. After one area is installed, the workers use the other end of the pole to support the woven fabric to move the second float and complete the construction of the drainage board in the adjacent area.

[0021] Furthermore, the method for using the aforementioned mechanized laying of woven fabric and modular insert system for deep silt layers also includes:

[0022] S10. Each side of the dike is equipped with a first floating body, a set of winches, and a vehicle. When the first floating body on the east side of the dike is pulled 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 moves a distance along the north-south direction, the first floating body is connected to the winch on the east side of the dike by a traction rope. When the first floating body is pulled to the east side of the dike by the winch on the east side of the dike, steps S6 to S9 are performed again. The above process is repeated to realize the laying of woven fabric and the insertion of drainage boards in the entire construction area.

[0023] Furthermore, in S9, when the operator uses the other end of the plug to support the woven fabric to move the second float, the gap between the plastic drainage board and the two lightweight foam boards slides and engages, thereby limiting and guiding the movement of the second float, so that the second float moves along the planned path.

[0024] Beneficial effects of this invention: Through the synergistic design of "mechanized laying + modular insert plate", this 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, and environmental adaptability. It provides a new solution for the treatment of soft soil foundations by hydraulic filling that is both economical and reliable, and has significant engineering application value and industry promotion significance. It greatly improves the construction efficiency and economy of mechanized laying of woven fabric and modular insert plate in deep silt layers, while reducing safety risks.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: As Figures 1 to 3As shown, a mechanized laying system for woven fabric in deep silt layers and a modular insert plate system include a woven fabric 3 to be laid on a first float 5, and a portion of the woven fabric 3 extending to the silt surface as a laid woven fabric 4. One side of the first float 5 is connected to a winch 8 via a traction rope 2. A second float 9 is provided on the surface of the laid woven fabric 4, and an insert rod 11 is provided on the second float 9. The insert rod 11 is made of Q235B steel pipe, with one end pointed and the other end flat.

[0031] Preferably, the first float 5 is a foam float structure with angle irons around its perimeter. A connecting ring 12 is provided on each angle iron, and the connecting ring 12 engages with one end of the traction rope 2. In this embodiment, the first float 5 is 20 cm thick.

[0032] Preferably, guardrails 1 are provided on the sides of the first float 5 and the second float 9. The guardrails 1 are 1.2m high, made of welded galvanized steel pipes, and painted with black and yellow warning paint on the outer wall. They are set along three sides of the first float 5, but not on the side where the woven fabric is laid.

[0033] Preferably, the winch 8 is fixedly mounted on the vehicle body, and an A-frame 7 is fixedly mounted on the vehicle body. A pulley 6 is mounted on the A-frame 7, and the traction rope 2 passes over the pulley 6 and connects to the winch 8. In this embodiment, the traction rope 2 is a 14mm diameter steel wire rope.

[0034] 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 made of galvanized steel pipe welded together; one end of the diagonal brace 13 is connected to the top of the A-frame 7 and the other end is connected to the vehicle body, and its main function is to reinforce the A-frame 7 and increase its stability; the diagonal brace 14 is made of steel pipe welded to the A-frame 7, and its main function is to reinforce the A-frame 7 and increase its stability.

[0035] Preferably, the second float 9 is a boat-shaped float structure, comprising two lightweight foam boards connected to each other, with a gap between the two lightweight foam boards. In this embodiment, a 20-centimeter gap is provided to facilitate the process of piercing the woven fabric using the pointed end of the insertion rod 11.

[0036] Preferably, the lightweight foam board is provided with reinforcing ribs 10 at the top and bottom. The reinforcing ribs 10 are made of 5cm wide flat iron; the reinforcing ribs 10 can enhance the strength of the lightweight foam board.

[0037] Embodiment 1 of the present invention has the following advantages:

[0038] I. Technical advantages brought about by structural design optimization;

[0039] 1.1 Stability and durability of the floating structure:

[0040] The first float adopts a structure combining a foam float and an angle iron frame. The angle iron on all four sides not only enhances the float's resistance to compression but also ensures a reliable connection to the towing rope through connecting rings, avoiding the deformation problem caused by insufficient load-bearing capacity of traditional foam boards. For example, the 20cm thick foam float combined with the angle iron frame can withstand the weight of workers and woven fabric, while reducing the impact of silt buoyancy fluctuations on the construction platform.

[0041] The second float's hull design (with a gap between two lightweight foam boards) combined with the top and bottom reinforcing ribs (5cm wide flat iron) reduces the overall weight and facilitates precise positioning of the insertion rod through the gap design. At the same time, the reinforcing ribs prevent the foam boards from cracking during repeated insertion operations, extending the equipment's service life.

[0042] 1.2 The mechanization advantages of the winch traction system:

[0043] The winch forms a stable traction power system through a combination of an A-frame, pulleys, and diagonal braces / studs. For example, the 14mm diameter steel wire rope, combined with the pulleys for steering, can apply traction force evenly, allowing the first float to move smoothly on the silt surface and avoiding the unevenness of the woven fabric laid due to manual dragging. The diagonal braces and studs reinforce the A-frame, preventing equipment tilting due to uneven force during traction and ensuring the reliability of the system operation.

[0044] 1.3 Safety Protection Details Design:

[0045] The edges of the first and second floats are equipped with 1.2m high galvanized steel pipe guardrails, and the outer walls are painted with black and yellow warning paint. Except for the paving side, the three sides are protected, which can effectively prevent workers from falling. Compared with the traditional foam board platform without guardrails, the risk of safety accidents is reduced by about 70%.

[0046] II. Efficiency improvement through mechanization and modularization of the construction process;

[0047] 2.1 Automation and Precision Control of Woven Fabric Laying:

[0048] When the winch pulls the first float to move, the woven fabric automatically spreads out with the help of the silt's adhesive force, requiring only a small amount of manual assistance to complete the large-area laying. Compared with traditional manual paving, the daily laying efficiency of a single machine can be increased by 3-5 times (for example, traditional manual paving is about 500㎡ per day, while this system can reach 2000-2500㎡), and the laying is more even, reducing the obstruction of drainage boards caused by wrinkles.

[0049] The woven fabric to be laid is placed on the first float in a stacked manner. With the tension control during the traction movement, the woven fabric can be prevented from being overstretched or folded, reducing the material loss rate (from 15% of the traditional manual method to below 5%).

[0050] 2.2 Positioning accuracy and efficiency of modular inserts:

[0051] The two foam boards of the second float are spaced 20cm apart, which mates with the tip of the insertion rod. This allows for precise positioning of the drainage board insertion location at preset intervals (e.g., 1-2m), avoiding errors from manual measurement. The insertion rod is made of Q235B steel pipe, with one end pointed like a rag and the other end flat on the ground, achieving an integrated operation of "rag tearing-board insertion-movement". The time for inserting a single drainage board is reduced from 2-3 minutes in traditional manual methods to 40-60 seconds.

[0052] The sliding fit design between the plastic drainage board and the foam board forms a limiting guide when the second float moves, allowing the workers to move along the planned path, avoiding deviations in the drainage board spacing caused by blind movement, and ensuring the uniformity of the foundation treatment.

[0053] III. Environmental adaptability and engineering economics expansion;

[0054] 3.1 Feasibility of construction under complex geological conditions:

[0055] For deep silt layers (bearing capacity <5kPa), traditional manual construction requires laying multiple layers of foam boards and is prone to getting stuck in the silt. However, this system, through the buoyancy support of the first float and remote traction by a winch, can operate directly on the silt surface without the need to build an additional temporary platform, saving about 30-40% of the platform construction cost.

[0056] The design of alternating traction by winches on both sides of the dike (step S10) can realize the cyclic operation of "laying-insertion-return laying", without the need for secondary equipment transfer. It is particularly suitable for narrow and long reclamation areas (such as ports and river management projects), and the construction coverage can be extended to more than twice that of traditional methods.

[0057] 3.2. Full lifecycle cost optimization:

[0058] Mechanized operations reduce labor input (each piece of equipment requires only 2-3 workers, compared to 8-10 workers using traditional methods), which can reduce labor costs by 50-60% based on daily construction costs. At the same time, equipment components (such as floats and winches) can be reused, resulting in lower amortization costs per project. Compared to disposable foam board platforms, material costs are reduced by approximately 60%.

[0059] The silt brought out during the insertion process floats on the surface of the woven fabric, which can naturally form a friction-reducing layer, reduce the resistance to the movement of the second float, indirectly improve construction efficiency, and at the same time avoid silt accumulation affecting drainage effect and reduce later cleaning costs.

[0060] IV. Technological innovation drives industry standards;

[0061] 4.1 Standardized and modular construction paradigms:

[0062] All components of the system (floating body, traction device, insertion rod) adopt standardized designs (such as A-frame dimensions and pulley specifications), allowing for flexible combinations based on project scale and facilitating industry adoption. The modular insertion plate process (positioning-insertion-relocation) forms a standardized construction technique, improving the quality controllability of foundation treatment projects.

[0063] 4.2 Green Construction and Sustainability:

[0064] Compared to the significant loss and disposal of foam boards in traditional manual construction, this system allows for the reuse of equipment, reducing solid waste emissions. Mechanized operations reduce energy consumption (energy consumption per square meter is reduced by approximately 40% compared to traditional methods), aligning with the concept of green construction and making it particularly suitable for soft soil foundation treatment projects in ecologically sensitive areas.

[0065] Example 2: This example discloses the method of using the above-mentioned mechanized laying of woven fabric and modular insert system for deep silt layers, which includes the following steps:

[0066] S1. First, place the first float 5 on the silt layer on one side of the dike, so that it floats on the silt, and then drive the vehicle to the other side of the dike.

[0067] S2. Then the traction rope 2 of the winch 8 is released and connected to the first float 5.

[0068] 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;

[0069] S4. Start the winch 8 and gradually retract the traction rope 2. Under the traction of the traction rope 2, the first float 5 can move.

[0070] S5. During the movement of the first float 5, the woven fabric 3 to be spread will automatically unfold due to the adhesive force of the silt, thus forming a spread woven fabric 4 in contact with the silt surface. If the spreading is not smooth, only manual assistance from the operator is required, resulting in high construction efficiency. In this embodiment, the woven fabric 3 to be spread is placed in a stacked manner for easy spreading.

[0071] S6. After the woven fabric is laid, the surface of the silt is initially ready for operation, and then the second float 9 is placed on the woven fabric.

[0072] S7. The operator stands on the second float 9 and places the pre-cut plastic drainage board on the second float 9 at the same time.

[0073] S8. According to the set spacing of the plastic drainage boards, through the gap between the two lightweight foam boards, use the pointed end of the insertion rod 11 to puncture the woven fabric, thereby inserting the plastic drainage 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 fabric, which can reduce the friction between the second float 9 and the woven fabric to a certain extent.

[0074] S9. After the installation of the drainage board in one area is completed, the workers use the other end of the insertion rod 11 to support the woven fabric, thereby shifting the second float 9 and completing the drainage board installation in the adjacent area. In this step, the process of shifting the second float 9 by supporting the woven fabric with the other end of the insertion rod 11 is similar to using a bamboo pole to propel a boat.

[0075] S10. Each side of the dike is equipped with a first floating body 5, a set of winches 8, and a vehicle. When the first floating body 5 on the east side of the dike is pulled to the west side by the winch 8 on the west side, steps S6 to S9 are performed. Then, after the vehicle moves a distance along the north-south direction, the first floating body 5 is connected to the winch 8 on the east side of the dike again via a traction rope 2. When the first floating body 5 is pulled to the east side of the dike by the winch 8, steps S6 to S9 are repeated. This process is repeated to achieve the laying of woven fabric and the installation of drainage boards throughout the construction area. The above process allows the woven fabric to be laid simultaneously by using the winch traction device on the opposite side to pull the floating body back. This cycle is repeated to efficiently lay the woven fabric.

[0076] Furthermore, in S9, when the operator uses the other end of the plug rod 11 to support the woven fabric to move the second float 9, the gap between the plastic drainage board and the two lightweight foam boards slides and engages, thereby limiting and guiding the movement of the second float 9, so that the second float 9 moves along the planned path.

[0077] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
