A geotextile underwater paving equipment

Abstract

This invention belongs to the field of geotextile paving technology, specifically a geotextile underwater paving equipment. The proposed solution includes a working boat and two lowering frames. The two lowering frames are connected to the same guide roller on opposite sides via bearings, and an anti-impact component is provided between the two lowering frames for the guide roller. By incorporating a gravity flattening component, this invention addresses the issue that after geotextile paving, the underwater geotextile is prone to localized floating due to buoyancy. During the paving process, the wave-shaped pressure plate moves with the working boat. Under the pressure of the counterweight and the water, the moving wave-shaped pressure plate exerts a gravity compression effect on the paved geotextile, resulting in closer contact between the paved geotextile and the underwater soil. Simultaneously, the pressure from the counterweight and the water on the wave-shaped pressure plate is weakened by the elastic connecting rod, preventing excessive compression and damage to the geotextile.

Description

Technical Field

[0001] This invention relates to the field of geotextile paving technology, and more particularly to an underwater geotextile paving equipment. Background Technology

[0002] When treating soft foundations such as tidal flats in the sea, it is often necessary to lay underwater geotextiles as isolation, protection and filter layers. The traditional method is to lay them directly on the deck of a ship and then lay them in the water. Due to the influence of water flow and water depth, the geotextiles are easily floated or folded, and sometimes they are easily washed away by the water, resulting in losses. The operation efficiency is low and the quality is difficult to guarantee.

[0003] During the existing underwater geotextile paving process, as the water depth increases and the water flow speed increases, the geotextile located outside the guide roller is prone to shifting due to the impact of the water flow. At the same time, the geotextile located between the spreading roller and the guide roller, due to its larger area, is subjected to more significant impact and is more likely to shift. This will cause the geotextile to fold over a large area due to the impact of the external water flow during paving, resulting in the geotextile isolation and protection area after paving being far below the standard value, thereby reducing the usability of the paving device. Summary of the Invention

[0004] This invention proposes an underwater geotextile paving device, comprising a working boat and two descending frames. The two descending frames are connected to the same guide roller via bearings on opposite sides. An anti-impact component is provided between the two descending frames on the guide roller. An end-point limiting component is located below the working boat. The anti-impact component includes an adjusting ring plate. Two hydraulic cylinders are fixedly connected to the side of the descending frame facing the adjusting ring plate. The output ends of both hydraulic cylinders are fixedly connected to the outer side of the adjusting ring plate. Multiple layers of annular friction plates are provided on the outer side of the adjusting ring plate away from the descending frame. Two extension frames are fixedly connected to the outer side of the adjusting ring plate, and the two extension frames are arranged at a 90° angle. The extended frame is fixedly connected with right-angle frames at equal intervals inside, and each right-angle frame is fixedly connected with an extrusion plate on one side. Each extrusion plate is fixedly connected with friction blocks at equal intervals on the side facing the inside of the right-angle frame. The other side of the right-angle frame is fixedly connected with a shaft frame, and the shaft frame is connected to a smoothing roller through a bearing on the outer side facing the extrusion plate. The arc surface of the smoothing roller is on the same horizontal plane as the friction block. The smoothing roller, which is horizontal with the geotextile, provides a smoothing effect, ensuring that the geotextile can be smoothly laid underwater. The extended frame provides a two-sided protection for the geotextile between the laying roller and the guide roller, further preventing water flow impact.

[0005] As a further embodiment of the present invention, the endpoint limiting component includes a limiting post, and both ends of the limiting post are fixedly connected to pile posts. The limiting post has an inner groove inside and an inlet / outlet perforation outside. The inlet / outlet perforation is connected to the inner groove. The limiting post is provided with a flow guide arc rod on the outer side of the inlet / outlet perforation. By setting the flow guide arc rod with an arc surface, the friction damage to the geotextile when passing through the inlet / outlet perforation of the limiting post is reduced, and the endpoint of the geotextile is protected.

[0006] As a further embodiment of the present invention, hydraulic rods are fixedly connected at equal intervals to the bottom inner wall of the inner groove, and the output ends of multiple hydraulic rods are fixedly connected to the same limiting arc plate. The limiting arc plate is fixedly connected at equal intervals to the outer side facing the inner groove with staggered teeth. Matching rods are fixedly connected at equal intervals to the top inner wall of the inner groove. The matching rods and staggered teeth are staggered and arranged. The staggered arrangement of the matching rods and staggered teeth squeezes the geotextile into a disordered state, so that the impact of water cannot cause any displacement of the ends of the geotextile, thus ensuring the firmness of the geotextile ends.

[0007] As a further embodiment of the present invention, a winch is fixedly connected inside the workboat, and an installation plate is fixedly connected to the top of the workboat. A guide rail is fixedly connected to one side of the installation plate, and a lifting block is slidably connected inside the guide rail. One end of the wire rope on the winch is connected to the lifting block, and an installation frame is fixedly connected to one side of the lifting block.

[0008] As a further embodiment of the present invention, a motor is fixedly connected to one side of the mounting frame, and the output shaft of the motor is fixedly connected to a fabric feeding roller via a coupling. The other end of the fabric feeding roller is connected to the inner side of the mounting frame via a bearing.

[0009] As a further embodiment of the present invention, mounting blocks are fixedly connected to both sides of the mounting frame, and cylinders are fixedly connected to the bottom of both mounting blocks. The output ends of both cylinders are fixedly connected to the top of the lowering frame. Connecting long plates are fixedly connected to both sides of the two lowering frames, and counteracting components are provided at the bottom of both connecting long rods. By setting counteracting components, during the paving process of the geotextile, the No. 2 hydraulic cylinder is adjusted to drive the adjusting frame to move. During the movement of the adjusting frame, the impact smoothing rollers located on both sides of the geotextile have a pushing and smoothing effect on the geotextile. The moving impact smoothing rollers have a counteracting effect on the water flow impact at both ends of the geotextile, thereby reducing the impact of water flow impact on the geotextile and further improving the flatness of the paved geotextile.

[0010] As a further embodiment of the present invention, the counteracting component includes an intermediate plate and an impact smoothing roller, wherein the intermediate plate is fixedly connected to the bottom of the connecting long plate, and two hydraulic cylinders are fixedly connected to both sides of the intermediate plate, and an adjustment frame is fixedly connected to the output end of each of the two hydraulic cylinders.

[0011] As a further embodiment of the present invention, the inner side of the adjusting frame is connected to a shaft via a bearing, and buffer spring rods are distributed in a ring on the outer side of the shaft. The other ends of multiple buffer spring rods located in the same column are fixedly connected to the same roller frame, and the two ends of the impact smoothing roller are connected to the inner side of the roller frame via bearings.

[0012] As a further embodiment of the present invention, two gravity flattening components are provided on the outer side of one of the connecting plates, and the two gravity flattening components are symmetrical about the working boat.

[0013] As a further embodiment of the present invention, the gravity flattening assembly includes a connecting frame and a corrugated pressing plate. The connecting frame is fixedly connected to the outside of the connecting long plate. The bottom of the connecting frame is provided with multiple elastic connecting rods, and the other end of the multiple elastic connecting rods is located on the outside of the corrugated pressing plate. The top of the connecting frame is fixedly connected with a counterweight frame, and multiple counterweight blocks are inserted into the counterweight frame. During the geotextile laying process, the corrugated pressing plate moves with the movement of the work boat. Under the pressure of the counterweight blocks and the water, the moving corrugated pressing plate exerts a gravity compression effect on the laid geotextile, thereby making the laid geotextile more tightly contacted with the underwater soil.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. By incorporating anti-impact components, during the geotextile spreading operation, the geotextile on the spreading roller passes through the guide roller. One end of the geotextile is limited by the end-point limiting component, allowing it to pass through the extended frame outside each adjusting ring plate. When the geotextile is impacted by water flow in the vertical direction, the annular friction plates and friction blocks provide an anti-impact effect, acting as a barrier in the vertical direction to prevent the geotextile from folding or shifting due to water flow impact. Simultaneously, the smoothing roller, which is horizontal with the geotextile, provides a smoothing effect, ensuring that the geotextile can be smoothly spread underwater. The extended frame provides lateral protection for the geotextile between the spreading roller and the guide roller, further mitigating the impact of water flow and ensuring that the protected area after geotextile spreading is close to the standard area, thus improving the usability of the spreading device.

[0016] 2. By setting up a counteracting component, during the paving process, the No. 2 hydraulic cylinder drives the adjustment frame to move. During the movement of the adjustment frame, the impact smoothing rollers located on both sides of the geotextile have a pushing and smoothing effect on the geotextile. The moving impact smoothing rollers have a counteracting effect on the water flow impact at both ends of the geotextile, thereby reducing the impact of water flow impact on the geotextile and further improving the flatness of the paved geotextile.

[0017] 3. By incorporating a gravity flattening component, after the geotextile is laid, the geotextile located underwater is prone to localized floating due to the buoyancy of the water. In this invention, during the geotextile laying process, the wave-shaped flattening plate moves with the working vessel. Under the pressure of the counterweight and the water, the moving wave-shaped flattening plate exerts a gravity compression effect on the laid geotextile, thereby making the laid geotextile more tightly connected to the underwater soil. At the same time, the force exerted by the counterweight and the water on the wave-shaped flattening plate is weakened by the buffering of the elastic connecting rod, preventing excessive compression from damaging the geotextile and protecting it.

[0018] 4. By setting an end-limiting component, when limiting one end of the geotextile, one end of the geotextile is passed through the inner groove inside the limiting column. The hydraulic rod is adjusted to drive the misaligned teeth on the limiting arc plate to squeeze the geotextile, thereby making the geotextile snap into the various matching rods, forming a misaligned fit effect, realizing the firm limitation of the end of the geotextile, and ensuring that the geotextile will not fall off when subjected to impact.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-9An underwater geotextile paving device includes a workboat 1 and two descending frames 13. The two descending frames 13 are connected to the same guide roller 11 via bearings on opposite sides. An anti-impact component 10 is provided between the two descending frames 13 on the guide roller 11. An end-point limiting component 15 is provided below the workboat 1. The anti-impact component 10 includes an adjusting ring plate 1001. Two hydraulic cylinders 1002 are fixedly connected to the side of the descending frame 13 facing the adjusting ring plate 1001. The output ends of both hydraulic cylinders 1002 are fixedly connected to the outer side of the adjusting ring plate 1001. The outer side of the adjusting ring plate 1001 away from the descending frame 13 is provided with multiple layers of annular friction plates 1004. Two extension frames 1003 are fixedly connected to the outer side of the ring plate 1001. The two extension frames 1003 are arranged at a 90° angle. Right angle brackets 1006 are fixedly connected at equal intervals inside the extension frames 1003. Each right angle bracket 1006 has a pressing plate 1009 fixedly connected to one side. Each pressing plate 1009 has friction blocks 1007 fixedly connected at equal intervals on the side facing the inside of the right angle bracket 1006. A shaft bracket 1005 is fixedly connected to the other side of the right angle bracket 1006. A smoothing roller 1008 is connected to the outer side of the shaft bracket 1005 facing the pressing plate 1009 through a bearing. The arc surface of the smoothing roller 1008 is on the same horizontal plane as the friction block 1007.

[0031] When the geotextile is impacted by water flow in the vertical direction, the annular friction plates 1004 and friction blocks 1007 provide an impact protection effect. The annular friction plates 1004 and friction blocks 1007 act as a barrier in the vertical direction, ensuring that the water flow impact does not cause the geotextile to fold or shift. At the same time, the smoothing roller 1008, which is horizontal to the geotextile, provides a smoothing effect, ensuring that the geotextile can be smoothly laid underwater. The extension frame 1003 provides lateral protection for the geotextile between the laying roller 8 and the guide roller 11, further protecting it from water flow impact and ensuring that the protected area after the geotextile is laid is close to the standard area.

[0032] Reference Figure 1 , Figure 8 and Figure 9 The endpoint limiting component 15 includes a limiting post 1501, and both ends of the limiting post 1501 are fixedly connected to a piling post 1502. The limiting post 1501 has an inner groove 1505 inside and an inlet / outlet through hole on the outer side. The inlet / outlet through hole is connected to the inner groove 1505. The limiting post 1501 is provided with a guide arc rod 1503 on the outer side of the inlet / outlet through hole.

[0033] In this invention, hydraulic rods 1504 are fixedly connected at equal intervals to the bottom inner wall of the inner groove 1505, and the output ends of multiple hydraulic rods 1504 are fixedly connected to the same limiting arc plate 1506. The limiting arc plate 1506 is fixedly connected at equal intervals to the outer side facing the inner groove 1505 with misaligned teeth 1507. The top inner wall of the inner groove 1505 is fixedly connected at equal intervals with mating rods 1508. The mating rods 1508 and the misaligned teeth 1507 are arranged in a misaligned manner.

[0034] When limiting one end of the geotextile, one end of the geotextile is passed through the inner groove 1505 inside the limiting post 1501. The hydraulic rod 1504 is adjusted to drive the misaligned teeth 1507 on the limiting arc plate 1506 to squeeze the geotextile, thereby making the geotextile snap into the various matching rods 1508, forming a misaligned fit, achieving a firm limit on the end of the geotextile, and ensuring that the geotextile will not fall off when subjected to impact.

[0035] Reference Figure 1 and Figure 2 The working boat 1 is fixedly connected to a winch 2 inside, and a mounting plate 5 is fixedly connected to the top of the working boat 1. A guide rail 4 is fixedly connected to one side of the mounting plate 5. A lifting block 3 is slidably connected inside the guide rail 4. One end of the wire rope on the winch 2 is connected to the lifting block 3. A mounting frame 6 is fixedly connected to one side of the lifting block 3. A motor 7 is fixedly connected to one side of the mounting frame 6. The output shaft of the motor 7 is fixedly connected to a cloth-feeding roller 8 through a coupling. The other end of the cloth-feeding roller 8 is connected to the inside of the mounting frame 6 through a bearing.

[0036] Reference Figure 1 and Figure 6 Mounting blocks 16 are fixedly connected to both sides of the mounting frame 6, and cylinders 12 are fixedly connected to the bottom of both mounting blocks 16. The output ends of both cylinders 12 are fixedly connected to the top of the descending frame 13. Connecting plates 9 are fixedly connected to both sides of the two descending frames 13, and counteracting components 17 are provided at the bottom of both connecting rods.

[0037] In this invention, the counterbalancing assembly 17 includes an intermediate plate 1701 and an impact smoothing roller 1704. The intermediate plate 1701 is fixedly connected to the bottom of the connecting long plate 9. Two hydraulic cylinders 1702 are fixedly connected to both sides of the intermediate plate 1701. An adjusting frame 1705 is fixedly connected to the output end of each of the two hydraulic cylinders 1702. A shaft 1703 is connected to the inner side of the adjusting frame 1705 through a bearing. Buffer spring rods 1707 are distributed in a ring on the outer side of the shaft 1703. The other ends of multiple buffer spring rods 1707 located in the same column are fixedly connected to the same roller frame 1706. The two ends of the impact smoothing roller 1704 are connected to the inner side of the roller frame 1706 through bearings.

[0038] During the paving process, the No. 2 hydraulic cylinder 1702 drives the adjustment frame 1705 to move. During the movement of the adjustment frame 1705, the impact smoothing rollers 1704 located on both sides of the geotextile have a pushing and smoothing effect on the geotextile. The moving impact smoothing rollers 1704 have a counteracting effect on the water flow impact at both ends of the geotextile, thereby reducing the impact of water flow impact on the geotextile and further improving the flatness of the paved geotextile.

[0039] Reference Figure 1 and Figure 7 Two gravity flattening components 14 are provided on the outer side of one of the connecting long plates 9, and the two gravity flattening components 14 are symmetrical about the working boat 1. The gravity flattening component 14 includes a connecting frame 1405 and a wave pressing plate 1401. The connecting frame 1405 is fixedly connected to the outer side of the connecting long plate 9. Multiple elastic connecting rods 1402 are provided at the bottom of the connecting frame 1405. The other end of the multiple elastic connecting rods 1402 is provided on the outer side of the wave pressing plate 1401. A counterweight frame 1404 is fixedly connected to the top of the connecting frame 1405. Multiple counterweight blocks 1403 are inserted into the counterweight frame 1404.

[0040] During the geotextile laying process, the corrugated plate 1401 moves along with the working boat 1. Under the pressure of the counterweight 1403 and the water, the moving corrugated plate 1401 exerts a gravity compression effect on the laid geotextile, thereby making the laid geotextile more tightly connected to the underwater soil. At the same time, the force of the counterweight 1403 and the water on the corrugated plate 1401 is weakened by the buffer of the elastic connecting rod 1402, preventing excessive compression from damaging the geotextile and protecting the geotextile.

[0041] During use, before laying the geotextile, one end of the geotextile is passed through the inner groove 1505 inside the limiting post 1501. The hydraulic rod 1504 is adjusted to drive the misaligned teeth 1507 on the limiting arc plate 1506 to squeeze the geotextile, thereby causing the geotextile to be inserted between the various matching rods 1508, forming a misaligned fit effect, and achieving a firm fixation of the geotextile end. After the geotextile end is fixed, the pile post 1502 is pressed into the underwater soil, and the workboat 1 is started. When the geotextile is impacted by the water flow in the vertical direction, the various annular friction plates 1004 and friction blocks 1007 play an impact-resistant role against the geotextile. The annular friction plates 1004 and friction blocks 1007 play a vertical blocking role against the geotextile, ensuring that the water flow impact does not cause the geotextile to fold or shift. The smoothing roller 1008, which is horizontal with the geotextile, plays a smoothing role, ensuring that the geotextile can be smoothly laid underwater and extended. The frame 1003 provides lateral protection for the geotextile between the fabric-laying roller 8 and the guide roller 11. Simultaneously, during the geotextile spreading process, the second hydraulic cylinder 1702 moves the adjusting frame 1705. As the adjusting frame 1705 moves, the impact smoothing rollers 1704 on both sides of the geotextile push and smooth it. The moving impact smoothing rollers 1704 counteract the water flow impact on both ends of the geotextile, thus reducing the impact of the water flow. During the geotextile spreading process, the corrugated pressure plate 1401 moves with the working boat 1. Under the pressure of the counterweight 1403 and the water, the moving corrugated pressure plate 1401 exerts a gravity compression effect on the spread geotextile, making the spread geotextile more tightly connected to the underwater soil. After the geotextile is fully spread, the other end of the geotextile is restrained, ending the operation.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
