Description

Technical Field

[0001] The present invention relates to the technical field of scour protection of marine structures, and in particular to an integrated dumping and pouring construction device. Background Art

[0002] When marine structures (such as pile foundations and barrel foundations) are installed on the seabed, they alter the surrounding flow distribution, causing scour of the seabed surface surrounding the structures, forming localized scour pits. Scour pits are a significant factor affecting the long-term stability and operational safety of marine structures. Riprap protection is currently the most common and economical anti-scour measure for marine structures.

[0003] Currently, riprap construction typically involves dumping rocks directly from the sea or using chute pipes on construction vessels. While chute pipes can, to a certain extent, achieve more precise placement, the presence of rocks within the pipes hinders their movement, requiring only completion of riprap at one location before moving to the next. Achieving uniform distribution of the rocks requires the deployment of numerous locations and constant adjustment of the chute positions, significantly impacting construction efficiency. Furthermore, the quality of the riprap is significantly affected by water flow, and the placement of the riprap remains uncontrollable. Furthermore, the riprap accumulation has a weak ability to resist erosion, with rocks easily dispersed by water flow, resulting in a short-lived protection period. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that in order to ensure uniform laying of stones, materials need to be unloaded at a large number of points during riprap, the construction efficiency is low, and the riprap accumulation body has weak anti-scouring ability, thereby providing an integrated riprap and pouring construction device.

[0021] The present invention has the following advantages:

[0022] 1. The invention provides an integrated construction device for throwing, filling and pouring. A grouting pipe that can rotate around the chute is provided on the periphery of the chute. A jet head is provided at the tail end of the grouting pipe. The jet head is connected to the grouting pipe. The jet outlet of the jet head can be directed toward the tail end of the chute. The grouting pipe is connected to a pumping system. The pumping system can pump fluid into the grouting pipe to affect the landing point of the riprap. When the chute is fixed at a point, the grouting pipe and the pumping system cooperate to controllably lay stones around the tail end of the chute, so that the riprap is more evenly accumulated. On the seabed, on the other hand, it makes the riprap accumulation range of a single construction larger, reduces the frequency of moving the ship or adjusting the chute position, and shortens the construction time. In addition, the integrated filling and pouring construction device provided by the present invention integrates the riprap chute system with the slurry pouring system. The pumping system pumps slurry into the grouting pipe, and pours the riprap accumulation body through the injection head. The slurry can solidify the riprap accumulation body, making it less likely to be washed away by water flow, further improving the scouring resistance of the riprap accumulation body and extending the protection time of the riprap accumulation body.

[0023] 2. The present invention provides an integrated construction device for dumping, filling and pouring. The injection head is rotatably connected to the grouting pipe, and the angle between the injection head and the grouting pipe is adjustable. At the same time, a regulating valve is installed at the jet outlet. The regulating valve can change the flow rate at the outlet of the injection head by adjusting the opening size of the jet outlet, making it easier for the jet water flow to intervene in the riprap position, which is also beneficial for the later grouting.

[0024] 3. The integrated dumping and pouring construction device provided by the present invention has a chute that is a combined pipe structure with an overall retractable length. Its retractable length can be controlled by a traction assembly. At the same time, a rotating disk is rotatably provided on the base. The chute is connected to the rotating disk and can rotate around the base. In addition, the chute is hinged to the base, and the angle between the chute and the vertical line can be adjusted by the fourth drive assembly. The chute can flexibly replace the stone throwing point, and has stronger adaptability.

[0025] 4. The integrated dumping and pouring construction device provided by the present invention can be more conveniently used for seabed dumping near marine structures by adjusting the direction and speed of the high-pressure water flow to change the landing point of the riprap particles on the seabed, avoiding damage to the surface of the marine structure.

[0026] 5. The integrated riprap and pouring construction device provided by the present invention changes the pouring point by continuously adjusting the orientation of the grouting pipe and the injection head during the slurry pouring process, thereby changing the slurry pouring method from traditional single-point pouring to plane pouring. This overcomes the problem of excessive slurry concentration or overfilling caused by single-point pouring, and makes the filling more uniform and sufficient, thus achieving grid-based bonding of the riprap body. Combined with the adjustment of the chute position, it can efficiently complete the grid-based bonding of the riprap layer in the entire protection area. BRIEF DESCRIPTION OF THE DRAWINGS

The spray head 31 is in communication with the grouting pipe 30. The spray port of the spray head 31 is adapted to be directed toward the tail end of the chute 20.

[0047] The pumping system 50 is connected to the grouting pipe 30 via a first flexible pipe 51 . The pumping system 50 is suitable for pumping fluid into the grouting pipe 30 .

[0048] In this embodiment, a grouting pipe 30 that can rotate around the chute 20 is provided on the circumference of the chute 20, and a nozzle 31 is provided at the tail end of the grouting pipe 30. The nozzle 31 is connected to the grouting pipe 30, and the jet port of the nozzle 31 can be directed toward the tail end of the chute 20. The grouting pipe 30 is connected to the pumping system 50, and the pumping system 50 can pump fluid into the grouting pipe 30 to affect the landing point of the riprap. When the chute 20 is fixed at a point, the circumference of the tail end of the chute 20 can be controlled by the cooperation of the grouting pipe 30 and the pumping system 50. The paving stones are laid, the number of actions of the chute 20 is reduced, and the efficiency of the filling construction is greatly improved. In addition, the filling and pouring integrated construction device provided by this embodiment integrates the riprap chute system and the slurry pouring system. The pumping system 50 pumps slurry into the grouting pipe 30, and pours the riprap accumulation body 60 through the injection head 31. The slurry can solidify the riprap accumulation body 60, making it less likely to be dispersed by water flow, further improving the anti-scouring ability of the riprap accumulation body 60 and extending the protection time of the riprap accumulation body 60.

[0049] In this embodiment, the installation position of the base 10 is not specifically limited. The base 10 can be installed on an offshore platform or on a ship hull.

[0050] In this embodiment, the structure of the chute 20 is not specifically limited. It only needs to have a passage suitable for the passage of stones. The cross-section of the passage of the chute 20 is preferably circular or square to reduce the blockage of riprap in the chute 20. Furthermore, a multi-beam sounding system is integrated at the end of the chute 20 to detect the shape of the riprap accumulation body 60 and the shape of the cemented riprap body 61, providing a reference for the subsequent position adjustment of the grouting pipe 30.

[0051] As a preferred embodiment, a collecting hopper 23 is installed at one end of the chute 20 close to the base 10 to facilitate loading.

[0052] In this embodiment, the structure of the pumping system 50 is not specifically limited. It can pump fluid into the grouting pipe 30 and change the water flow pressure of the injection head 31 by adjusting the pumping pressure. As an embodiment, it can include a single pump to inject fluid into the grouting pipe 30; as another embodiment, it can include multiple pumps, which are connected to the first flexible pipe 51, and can easily replace the fluid entering the grouting pipe 30. Specifically, it can include a high-pressure pump and a low-pressure pump. The high-pressure pump pumps seawater to adjust the riprap position to make the riprap laying more uniform, and the low-pressure pump pumps slurry to solidify the riprap accumulation body 60, further improving the anti-scouring ability of the riprap accumulation body 60.

[0053] In this embodiment, the slurry may be underwater concrete that can solidify the riprap accumulation body 60 , and the material ratio may be adjusted according to actual needs.

[0054] On the basis of the above embodiment, in a preferred embodiment, the integrated filling and pouring construction device further includes a protective agent pouring pipe 40, which is connected to the pumping system 50 through a second flexible pipe. The protective agent pouring pipe 40 can be connected to the slide pipe 20. Figure 2 , which can also be connected to the grouting pipe 30, which is not specifically limited here.

[0055] refer to Figure 7 In this embodiment, when the grouting pipe 30 discharges the slurry, the pumping system 50 simultaneously pumps the underwater protective agent into the protective agent pouring pipe 40. Figure 7 D in the middle represents the protection range of the underwater protective agent. The underwater protective agent can prevent the slurry from dispersing in seawater, further improving the filling effect.

[0056] In this embodiment, the connection method between the injection head 31 and the grouting pipe 30 is not specifically limited. As one embodiment, the injection head 31 is welded to the tail end of the grouting pipe 30; as another embodiment, the injection head 31 is rotatably connected to the grouting pipe 30, and a second drive assembly is provided between the injection head 31 and the grouting pipe 30, and the second drive assembly is suitable for adjusting the angle between the injection head 31 and the grouting pipe 30.

[0057] In this embodiment, the injection head 31 is rotatably connected to the grouting pipe 30, and the angle between the injection head 31 and the grouting pipe 30 is adjustable, so that the injection water flow can flexibly intervene in the riprap position, which is also beneficial to the subsequent grouting.

[0058] There is no specific limitation on the specific structure of the second drive assembly. As an embodiment, the injection head 31 is connected to the grouting pipe 30 through a hose. A cylinder is fixed to the outer wall of the grouting pipe 30. The push rod of the cylinder is hinged to the injection head 31. The cylinder can adjust the angle between the injection head 31 and the grouting pipe 30 in real time by telescopic push rod. Usually, the angle between the injection head 31 and the grouting pipe 30 is 0° to 60°.

[0059] In a preferred embodiment, the jet port is equipped with a regulating valve, which is suitable for adjusting the opening size of the jet port.

[0060] In this embodiment, the regulating valve can change the flow rate at the outlet of the injection head 31 by adjusting the opening size of the jet port, so as to facilitate the injection of water flow to intervene in the riprap position, which is also beneficial to the subsequent grouting.

[0061] Furthermore, the spray head 31 is provided with a water flow detection device for detecting the natural water flow velocity, which can provide a reference for the subsequent adjustment of the high-pressure seawater spray velocity.

[0062] On the basis of the above embodiment, in a preferred embodiment, the chute 20 is a combined pipe structure with an overall retractable length, and the integrated filling and pouring construction device also includes a traction assembly 21, which is connected to at least one section of the chute 20, and the traction assembly 21 is suitable for adjusting the telescopic length of the chute 20.

[0063] In this embodiment, the slide pipe 20 is a combined pipe structure with an overall retractable length. The retractable length thereof is controlled by the traction assembly 21 , and the slide pipe 20 has stronger adaptability.

[0064] In this embodiment, there is no specific limitation on the number of pipe sections of the slide pipe 20. As an embodiment, it can be greater than two; as another embodiment, it can also be two. Specifically, the slide pipe 20 includes a first outer tube 201 and a first inner tube 202. The first outer tube 201 is sleeved on the first inner tube 202 and is slidably connected to the first inner tube 202. The traction assembly 21 is suitable for driving the first outer tube 201 to slide relative to the first inner tube 202.

[0065] In this embodiment, the slide pipe 20 is formed by connecting two pipe sections. The number of pipe sections is small, which is conducive to the traction component 21 controlling the telescopic length of the slide pipe 20.

[0066] In this embodiment, the structure of the traction assembly 21 is not specifically limited. As an embodiment, the traction assembly 21 includes a cylinder, the cylinder body is fixedly connected to the first inner tube 202, the cylinder push rod is connected to the first outer tube 201, and the cylinder can adjust the telescopic length of the slide tube 20 by telescopic push rod; as another embodiment, refer to Figure 1 The traction assembly 21 includes a hoist 211 and a suspension rope 212. The hoist 211 is connected to the base 10. One end of the suspension rope 212 is wound around the hoist 211 and the other end is connected to the slide pipe 20. Figure 1 , specifically, it is fixedly connected to the first outer tube 201 located below the first inner tube 202. Further, refer to Figure 3The lifting rope 212 is fixedly connected to the tail end of the slide pipe 20 extending underwater to prevent the slide pipe 20 from forming a long cantilever beam structure, making the slide pipe 20 structure more stable and less prone to deformation during construction. In addition, a fixed pulley 213 is provided on the slide pipe 20 and the base 10 to facilitate adjusting the steering of the lifting rope 212.

[0067] On the basis of the above embodiment, in a preferred embodiment, the grouting pipe 30 includes a second outer tube 301 and a second inner tube 302, the second outer tube 301 is sleeved on the second inner tube 302 and is slidingly connected to the second inner tube 302; the second inner tube 302 is rotationally connected to the first outer tube 201 and one of the first inner tube 202, and the second outer tube 301 is rotationally connected to the other of the first inner tube 202 and the first outer tube 201.

[0068] Specifically, refer to Figure 2 The outer wall of the first inner tube 202 is provided with a first slide rail 203, and the setting direction of the first slide rail 203 is consistent with the extension direction of the first inner tube 202. The inner wall of the first outer tube 201 is correspondingly provided with a first slide groove 204, and the first slide rail 203 is inserted into the first slide groove 204 to realize the sliding connection between the first outer tube 201 and the first inner tube 202; similarly, the outer wall of the second inner tube 302 is provided with a second slide rail 303, and the setting direction of the second slide rail 303 is consistent with the extension direction of the second inner tube 302, and the inner wall of the second outer tube 301 is correspondingly provided with a second slide groove 304, and the second slide rail 303 is inserted into the second slide groove 304 to realize the sliding connection between the second outer tube 301 and the second inner tube 302; the protective agent casting pipe can also adopt a combined pipe structure, which includes a third outer tube and a third inner tube, and the third outer tube is sleeved on the third inner tube and slidably connected to the third inner tube.

[0069] In this embodiment, the inner tube and the outer tube are slidably connected, which can limit the rotation of the inner tube relative to the outer tube, making the tube structure more stable and controllable during construction.

[0070] In this embodiment, the structure of the first drive assembly is not specifically limited. As an implementation method, a bearing 22 is fixedly installed on the outer peripheral side of the chute 20, and the outer side of the bearing 22 is fixedly connected to the grouting pipe 30. A force gear is installed on the outer peripheral side of the chute 20, and an electric motor is fixed on the outer peripheral side of the grouting pipe 30. The output shaft of the motor is fixed with an output gear that is adapted to the force gear. The output gear and the force gear are engaged for transmission. The rotation of the motor can realize the rotation of the grouting pipe 30 around the chute 20. During the process of riprap and slurry pouring, the grouting pipe 30 generally rotates by 90° to 120° relative to the chute 20 each time.

[0071] Furthermore, a groove is provided on the outer side of the bearing 22 for facilitating the winding of the flexible tube. Before the installation, the flexible tube is wrapped around the groove of the bearing 22 for 1-2 times to avoid pulling on the flexible tube when the grouting tube 30 rotates relative to the slide tube 20 during construction, thereby affecting the spraying of water or grouting.

[0072] For further reference, Figure 1 and Figure 3 A plurality of bearings 22 are provided between the slide pipe 20 and the grouting pipe 30 to improve the rotation stability of the grouting pipe 30 .

[0073] Based on the above embodiment, in a preferred embodiment, a rotating disk 11 is rotatably provided on the base 10, and a third driving assembly is provided between the rotating disk 11 and the base 10. The third driving assembly is suitable for driving the rotating disk 11 to rotate relative to the base 10, and the slide pipe 20 is connected to the rotating disk 11.

[0074] In this embodiment, a rotating disk 11 is rotatably provided on the base 10, and the slide pipe 20 is connected to the rotating disk 11 to rotate around the base 10, so as to facilitate the replacement of the riprap point.

[0075] In this embodiment, the structure of the third drive assembly is not specifically limited. As an implementation method, the third drive assembly includes a motor and an output gear. The output gear is fixed to the output shaft of the motor. The outer peripheral side of the rotating disk 11 is evenly distributed with teeth that are adapted to the output gear. The output gear is engaged with the rotating disk 11 for transmission. The rotation of the output shaft of the motor can drive the rotating disk 11 to rotate relative to the base 10. Usually, the rotation angle of the rotating disk 11 relative to the base 10 is (-30)° to 30°.

[0076] On the basis of the above embodiment, in a preferred embodiment, the base 10 is hinged to the slide pipe 20, and a fourth drive assembly 12 is provided between the base 10 and the slide pipe 20. The fourth drive assembly 12 is suitable for adjusting the angle between the slide pipe 20 and the vertical line. Specifically, refer to Figure 1 A support base 101 is fixed on the rotating disk 11, the slide pipe 20 is hinged to the support base 101, and a fourth driving component 12 is provided between the slide pipe 20 and the support base 101. The fourth driving component 12 is suitable for adjusting the swing amplitude of the slide pipe 20 relative to the support base 101.

[0077] In this embodiment, the structure of the fourth drive assembly 12 is not specifically limited. As an embodiment, the fourth drive assembly 12 includes a cylinder, the cylinder body of the cylinder is fixedly connected to the rotating disk 11, the push rod of the cylinder is hinged to the slide 20, and the cylinder realizes the amplitude change of the slide 20 by controlling the contraction of the push rod. The angle between the slide 20 and the vertical line can usually be adjusted to 0°-45°.

[0078] It is easy to imagine that when the base 10 is not provided with the rotating disk 11 , the slide pipe 20 can be directly hinged to the base 10 , and the angle between the slide pipe 20 and the vertical line can be adjusted by the fourth driving assembly 12 .

[0079] Based on the above specific implementation methods, the working process of the integrated filling and pouring construction device of this embodiment is as follows:

[0080] S1. The base 10 is installed on the deck of a riprap vessel, and the riprap vessel is moved to the sea surface of the seabed riprap design area of the marine structure;

[0081] S2. First, adjust the horizontal position of the support base 101 using the rotating disk 11 according to the designed location of the riprap point. Then, adjust the vertical angle of the chute 20 using the fourth drive assembly 12. Then, use the traction assembly 21 to adjust the length of the chute 20, grouting pipe 30, and protective agent pouring pipe 40 until the tail end of the chute 20 is 1m-2m away from the riprap point.

[0082] S3, continuously filling the chute 20 with riprap particles through the collecting hopper 23, and the riprap particles are deposited on the seabed or scour pit in the riprap design area under the action of their own weight and natural water flow;

[0083] S4. Turn on the pumping system 50 and pump high-pressure seawater into the grouting pipe 30. The jet head 31 forms a water flow influence zone at the bottom of the chute 20 to change the landing point of the riprap particles. The riprap particles are deposited on the seabed or scour pit in the riprap design area along the direction of the water flow. During the riprap process, the positions of the grouting pipe 30 and the jet head 31 are continuously adjusted by the first drive component, that is, the water flow direction of the water outlet of the jet head 31 is changed. At the same time, the seawater pumping pressure is adjusted by the pumping system 50 to change the water flow pressure of the jet outlet, so that the riprap is evenly thrown on the seabed or scour pit in the riprap design area to form a uniform riprap layer (refer to Figure 4 、 Figure 5 and Figure 6 , Figure 4 This is a schematic diagram of the operation of the device when the pumping system 50 is not activated. The riprap accumulation body 60 tends to form a tapered structure that is narrow at the top and wide at the bottom, which has poor stability. Figure 5 To enable the pumping system 50, the working diagram when the water flow direction is B is shown, and the riprap is piled more evenly. Further, as shown in FIG. Figure 6 As shown, the grouting pipe 30 is rotated to adjust the water flow direction to C, so that the accumulation area of a single riprap point is larger and the accumulation is more uniform);

[0084] S5. After the riprap work on the seabed or scour pit in the riprap design area is completed, the length of the chute 20, the grouting pipe 30 and the protective agent pouring pipe 40 is adjusted by the traction assembly 21 until the distance between the jet outlet and the riprap layer is 0.5m-1m. The pumping system 50 is turned on to pump low-pressure slurry into the grouting pipe 30. The slurry is poured on the surface of the riprap layer through the injection head 31 to convert the riprap accumulation body 60 into a cemented riprap body 61. At the same time, by continuously adjusting the position of the grouting pipe 30 and the injection head 31, the pouring point 602 is changed, so that the slurry pouring method is changed from traditional single-point pouring to plane pouring, which overcomes the problem of excessive slurry concentration or overfilling caused by single-point pouring. Figure 8 , densely distributed pouring points 602 are formed between the top 601 of the riprap pile and the outer edge 603 of the riprap pile, realizing the grid bonding of the riprap body. During the slurry pouring process, the pumping system 50 pours the underwater protective agent (reference Figure 7 , D in the figure represents the protection range of the underwater protective agent, which can slow down the dilution of the slurry and improve the pouring effect);

[0085] S6. Repeat steps S2-S5 until the uniform riprap and cementation construction of the seabed around the marine structure is completed to form a gridded cemented riprap protective structure.

[0086] Functionally, this embodiment integrates the riprap chute system with the slurry pouring system. The pumping system 50 can pour the riprap accumulation body 60 by pumping slurry into the grouting pipe 30, further shortening the construction time and improving overall construction efficiency. By changing the original accumulation form of the riprap through the slurry pouring system, that is, by changing the direction and speed of the high-pressure water flow, on the one hand, the riprap is more evenly deposited on the seabed, and on the other hand, the riprap accumulation range of a single construction is expanded, reducing the frequency of moving the ship or adjusting the position of the chute 20, and shortening the construction time. In addition, by adjusting the direction and speed of the high-pressure water flow to change the landing point of the riprap particles on the seabed, this integrated riprap filling and pouring construction device is more convenient for seabed riprap near marine structures, avoiding damage to the surface of the marine structure.

[0087] During the slurry pouring process, by continuously adjusting the orientation of the grouting pipe 30 and the injection head 31 and changing the pouring point 602, the slurry pouring method is transformed from traditional single-point pouring to flat pouring. This overcomes the problems of excessive slurry concentration or overfilling caused by single-point pouring, resulting in more uniform and sufficient filling and achieving a grid-like cementation of the riprap. Furthermore, combined with the adjustment of the position of the chute 20, a grid-like cementation of the riprap layer can be efficiently completed throughout the entire protection area.
