Description

Technical Field

[0001] This application relates to the field of geotextile concrete construction, and in particular to a deep-water construction device and method for geotextile concrete for riverbank protection. Background Technology

[0002] Geotextile bag concrete is a type of hydraulic structure formed by weaving geotextile into bags and then filling the bags with concrete. Its main purpose is to prevent slopes from being eroded.

[0003] When constructing geotextile concrete, geotextile bags are usually laid on the slope first, and then concrete is poured into the geotextile bags. However, for some deep water channels, the slope is submerged to a great depth, so underwater operations are required when laying geotextile bags, which is quite troublesome. In addition, after the geotextile bags are laid and the concrete is poured into them, the quality of the concrete molding will be affected by the water depth and water flow, resulting in poor quality of the geotextile concrete after molding. Summary of the Invention

[0004] To facilitate the construction of geotextile bags in deep-water channels, this application provides a device and method for deep-water construction of geotextile bag concrete for riverbank protection.

[0005] Firstly, this application provides a deep-water construction device for riverbank revetment using formwork concrete, employing the following technical solution:

[0006] A deep-water construction device for riverbank revetment using formwork concrete includes two construction vessels. A support mechanism for carrying formwork is installed between the two construction vessels. One end of the formwork is used to fix it to the revetment, and the other end of the formwork is used to place it on the support mechanism.

[0007] By adopting the above technical solution, when using the formwork bag, one end is fixed to the revetment, and the other end is placed on the supporting mechanism. Then, concrete is poured into the formwork bag. After the concrete has initially stabilized, the formwork bag is detached from the supporting mechanism, and the formwork bag is automatically laid on the revetment due to its own weight. Since the entire process of laying the formwork bag is done on the water, there is no need for operators to lay it underwater, which is simple and convenient. In addition, after the concrete inside the formwork bag has initially stabilized, the formwork bag is then placed against the revetment, which can reduce the impact of water flow and water pressure on the concrete inside the formwork bag and improve the quality of the concrete after molding.

[0008] Optionally, a support rod is rotatably connected to the construction vessel, and the construction vessel is equipped with a drive assembly for driving the support rod to rotate. The support mechanism is installed between the two support rods and rotates with the support rods. The rotation of the support rods causes the mold bag to disengage from the support mechanism.

[0009] By adopting the above technical solution, after the concrete inside the formwork bag is initially formed, the drive component drives the bearing rod to rotate, causing the formwork bag to detach from the bearing mechanism. During the rotation of the bearing rod, the formwork bag gradually approaches the revetment, which can buffer the impact of the formwork bag on the revetment and prevent the concrete inside the formwork bag from deforming or being damaged.

[0010] Optionally, a take-up roller is rotatably connected to one of the support rods, and a motor for driving the take-up roller to rotate is provided on the support rod. One end of the support mechanism is mounted on the take-up roller, and the other end of the support mechanism is detachably connected to another support rod.

[0011] By adopting the above technical solution, the motor drives the winding roller to rotate, thereby winding up the carrying mechanism and adjusting the length of the carrying mechanism to lay out different lengths of molded bags as needed.

[0012] Optionally, the supporting mechanism is a rope net.

[0013] By adopting the above technical solution and using rope net as the supporting mechanism, it is easy to roll up and can support the mold bag. The supporting mechanism has a simple structure and is easy to operate.

[0014] Optionally, the supporting mechanism is an inflatable cushion, and the construction vessel is equipped with an air pump for inflating or deflating the inflatable cushion.

[0015] By adopting the above technical solution, the air pump can inflate the air cushion, and by increasing the buoyancy of the water on the air cushion to support the formwork bag, the pressure on the construction vessel can be reduced, preventing the construction vessel from capsizing. When the support rod rotates to lay the formwork bag on the revetment, the air pump can be used to evacuate the air cushion to reduce the buoyancy of the water on the air cushion, thereby reducing the resistance generated when the formwork bag is released and facilitating the laying of the formwork bag on the revetment.

[0016] Optionally, a pressing mechanism is provided on the support rod where the take-up roller is located. The pressing mechanism is used to press the air cushion to block the gas flow of the air cushion.

[0017] By adopting the above technical solution, the pressing mechanism can press the air pad tightly, thereby preventing gas from entering the air pad at the position of the take-up roller.

[0018] Optionally, the pressing mechanism includes a pressure plate and a cylinder, wherein the cylinder drives the pressure plate to move along the thickness direction of the inflatable pad, and the pressure plate slides to press the inflatable pad.

[0019] By adopting the above technical solution, when the air pad is compressed, the cylinder is opened, which drives the pressure plate to move and compress the air pad, thereby blocking the flow of gas inside the air pad and preventing gas from entering the air pad at the position of the take-up roller.

[0020] Secondly, this application provides a method for deep-water construction of riverbank revetment using formwork concrete, employing the following technical solution:

[0021] A method for deep-water construction of concrete formwork bags for riverbank protection includes the following steps: Step 1: Position two construction vessels on the river surface and install a support mechanism between them; Step 2: Fix one end of the formwork bag to the riverbank and lay the other end of the formwork bag on the support mechanism; Step 3: Pour concrete into the formwork bag; Step 4: After the concrete pouring is completed, detach the support mechanism from the formwork bag.

[0022] By adopting the above technical solution and setting up the supporting mechanism, the laying and pouring of the formwork bag can be carried out on the water surface, eliminating the need for underwater operations by operators. This is simple and convenient. In addition, after the concrete inside the formwork bag has initially stabilized, the formwork bag is then placed against the revetment, which can reduce the impact of water flow and water pressure on the concrete inside the formwork bag and improve the quality of the concrete after molding.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. This application enables the laying and pouring of formwork bags to be carried out on the water surface through the setting of the bearing mechanism, eliminating the need for underwater operations by operators, which is simple and convenient. In addition, after the concrete inside the formwork bag has initially stabilized, the formwork bag is then attached to the revetment, which can reduce the impact of water flow and water pressure on the concrete inside the formwork bag and improve the quality of the concrete after molding.

[0025] 2. By setting up an inflatable cushion, this application allows the air pump to inflate the cushion during use. By increasing the buoyancy of the inflatable cushion with water, the pressure on the construction vessel can be reduced, preventing the construction vessel from capsizing.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application provides a deep-water construction device for riverbank revetment using formwork concrete.

[0036] Example 1;

[0037] Reference Figure 1 and Figure 2 The construction device includes two construction vessels 1. During construction, the length of the two construction vessels 1 is set along the width of the river channel. The sides of the construction vessels 1 that are close to each other are rotatably connected to a bearing rod 2. The rotation axis of the bearing rod 2 is set along the length of the river channel. The construction vessel 1 is equipped with a drive assembly for driving the bearing rod 2 to rotate. The length of the bearing rod 2 is set along the width of the river channel. A bearing mechanism is installed between the two bearing rods 2. The bearing mechanism is used to support the formwork bag 4. One end of the formwork bag 4 is fixed to the upper end of the revetment 3 by an anchor rod, and the other end of the formwork bag 4 is placed on the bearing mechanism.

[0038] In this embodiment, the drive component is a winch 5.

[0039] When laying the formwork bag 4, first fix one corner of the formwork bag 4 to the upper end of the revetment 3, place one end of the formwork bag 4 on the bearing mechanism, and then use a small transport boat (not shown in the figure) to unfold the formwork bag 4 along the length of the river channel. After unfolding, fix the other corner of the formwork bag 4 to the revetment 3, and then pour concrete.

[0040] Reference Figure 2 and Figure 3To accommodate different sizes of molded bags 4, the supporting mechanism uses a rope net 6. The length of the rope net 6 is set along the length of the river channel, and the width of the rope net 6 is set along the width of the river channel. One of the supporting rods 2 has an inner cavity 7, and a take-up roller 8 is rotatably connected in the inner cavity 7. The rotation axis and length of the take-up roller 8 are both set along the length of the supporting rod 2. A motor 9 is fixedly connected to the supporting rod 2, and the output shaft of the motor 9 is coaxially fixedly connected to the take-up roller 8. One end of the rope net 6 is fixedly connected to the take-up roller 8 in the length direction, and the other end of the rope net 6 is used to hang on the supporting rod 2 away from the take-up roller 8.

[0041] In this embodiment, when the rope net 6 is attached to the support rod 2, the end of the rope net 6 away from the winding roller 8 can be pulled to the side of the support rod 2 away from the winding roller 8 by a small transport boat, and then the operator can attach the rope net 6 to the support rod 2 away from the winding roller 8.

[0042] The implementation principle of the deep-water construction device for riverbank revetment using formwork concrete in Embodiment 1 of this application is as follows: During construction, two construction vessels 1 are moved to a suitable position and the distance between the two construction vessels 1 is controlled. Then, a small transport boat is used to pull open the rope net 6 and hang the rope net 6 on the bearing rod 2. Then, formwork bags 4 are laid. When laying formwork bags 4, one corner of the formwork bag 4 is fixed to the upper end of the revetment 3, and one end of the formwork bag 4 is placed on the rope net 6. Then, the small transport boat is used to unfold the formwork bag 4 along the length of the river. After unfolding, the other corner of the formwork bag 4 is fixed to the revetment 3. Then, concrete is poured. After the concrete has initially stabilized, the winch 5 is used to rotate the bearing rod 2 to make the formwork bag 4 detach from the rope net 6 until the formwork bag 4 is attached to the revetment 3.

[0043] To prevent the construction vessel 1 from capsizing, this application provides an embodiment 2 of a deep-water construction device for riverbank revetment formwork concrete.

[0044] Example 2;

[0045] Refer to 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the supporting mechanism adopts an inflatable cushion 10, which is long and narrow, and the thickness direction of the inflatable cushion 10 is set along the depth direction of the river channel.

[0046] Reference Figure 4 and Figure 6 One end of the inflatable pad 10 is fixedly connected to the take-up roller 8, and the other end of the inflatable pad 10 is connected to a hanging rod 11. A hook 12 is fixedly connected to the bearing rod 2 away from the take-up roller 8, and a hanging groove 13 is provided on the hanging rod 11 for the hook 12 to be hung.

[0047] An air pump 14 is fixedly connected to the support rod 2, which is away from the take-up roller 8, by screws. The air outlet of the air pump 14 is connected to a hose 15, and the other end of the hose 15 is used to connect to the hanging rod 11.

[0048] To prevent gas from entering the air cushion 10 at the position of the take-up roller 8, an opening 16 is provided on the support rod 2 for the air cushion 10 to pass through. A pressing mechanism is provided on the support rod 2 where the take-up roller 8 is located. The pressing mechanism includes a cylinder 17 and a pressure plate 18. A mounting frame 19 is fixedly connected to the upper surface of the support rod 2 where the take-up roller 8 is located. The cylinder 17 is fixedly connected to the mounting frame 19. The length direction of the cylinder 17 is set along the thickness direction of the air cushion 10. The pressure plate 18 is fixedly connected to the telescopic end of the cylinder 17. The length direction of the pressure plate 18 is set along the length direction of the support rod 2. The pressure plate 18 is located at the opening 16. The pressure plate 18 moves under the action of the cylinder 17 to press the air cushion 10, thereby blocking gas from entering the air cushion 10 at the position of the take-up roller 8.

[0049] The implementation principle of the deep-water construction device for riverbank revetment using formwork bag concrete in Embodiment 2 of this application is as follows: When pouring concrete into the formwork bag 4, the air pump 14 is used to inflate the air cushion 10, causing the air cushion 10 to expand and increase its buoyancy. Then, concrete is poured into the formwork bag 4. The air cushion 10 can reduce the pressure on the construction vessel 1 and prevent the construction vessel 1 from capsizing. When the formwork bag 4 is attached to the revetment 3, the air pump 14 is used to gradually deflate the air cushion 10 during the rotation of the bearing rod 2, thereby reducing the buoyancy of the air cushion 10 and facilitating its rotation.

[0050] This application also provides a method for deep-water construction of concrete formwork for riverbank protection, which includes the following steps:

[0051] Step 1: Position the two construction vessels 1 on the river surface and install a load-bearing mechanism between the two construction vessels 1;

[0052] Step 2: Unfold the support mechanism. Use a small transport boat to unfold the inflatable cushion 10 or rope net 6, so that the inflatable cushion 10 or rope net 6 is attached to the support rod 2 away from the take-up roller 8.

[0053] Step 3: Lay out the plastic bag 4, fix one corner of the plastic bag 4 to the upper end of the revetment 3, place one end of the plastic bag 4 on the rope net 6 or the inflatable mat 10, and then use a transport boat to unfold the plastic bag 4 along the length of the river channel. After unfolding, fix the other corner of the plastic bag 4 to the revetment 3.

[0054] Step 4: When using the air cushion 10 as a support mechanism, use the air pump 14 to inflate the air cushion 10 to make it expand.

[0055] Step 5: Pour concrete into formwork bag 4 using a grouting machine;

[0056] Step 6: After the concrete has initially stabilized, use the winch 5 to rotate the bearing rod 2 to detach the formwork bag 4 from the rope net 6 or the air cushion 10. When using the air cushion 10 as the bearing mechanism, while rotating the bearing rod 2 to detach the formwork bag 4 from the air cushion 10, use the air pump 14 to gradually deflate the air cushion 10.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
