Description

Technical Field

[0001] The present invention relates to the field of riprap construction, and in particular to a riprap conduit and an uninterrupted material feeding and regulating device thereof, a use method thereof, a riprap system and a riprap method. Background Art

[0002] Riprap operations are used to construct underwater foundations for marine engineering projects. Riprap is transported through the riprap system's riprap pipes and deposited on the seabed to facilitate the construction of underwater foundations. Because the seabed depth changes due to factors such as tides, the length of the riprap pipes must be adjusted to ensure a fixed height difference between the lower end of the pipe and the seabed, allowing the riprap to accumulate layer by layer. The riprap pipes consist of an outer pipe and an inner pipe inserted within it. The inner pipe is shorter than the outer pipe. The outer pipe is typically assembled from standard sections with flanges. Traditionally, to adjust the length of the outer pipe, the riprap system must interrupt the riprap supply and halt the riprap operation. Once the outer pipe is lengthened or shortened, the riprap supply is restored and the riprap operation resumes. Furthermore, during the length adjustment process, the outer pipe is suspended and supported by slings to prevent it from falling or becoming misaligned. Its disadvantages are: after the supply of riprap is interrupted, there is a risk of riprap in the riprap pipe being blocked, which will make it impossible to resume the riprap operation and the riprap accumulation construction. The blocked pipe needs to be cleared or replaced before the riprap operation can be resumed. Otherwise, the riprap pipe is prone to bursting or being unable to supply material downward, affecting the construction efficiency, construction period and construction safety of the riprap operation; due to the continuous change of water depth, the riprap pipe needs to be adjusted many times, and each adjustment construction time is long, resulting in uneven control of the thickness of the riprap accumulation, affecting the construction quality of the underwater foundation.

[0025] When the growth adjustment of the riprap tube needs to be controlled, the hydraulic cylinder between the two uppermost sliding platforms is synchronously controlled to be in an extended state, so as to control the sliding platform below the top and the outer tube supported by it to sink as a whole, so that the uppermost outer tube sinks relative to the top sliding platform through the outer tube lifting window in the open state, so that the inner tube extends relative to the outer tube without detaching, thus achieving a small increase and adjustment of the riprap tube;

[0026] When it is necessary to control the shortening adjustment of the riprap guide tube, the hydraulic cylinder between the two uppermost sliding platforms is synchronously controlled to be in a retracted state to control the sliding platform below the top and the outer guide tube supported by it to rise as a whole, so that the uppermost outer guide tube rises relative to the top sliding platform through the outer guide tube lifting window in the open state, so that the inner guide tube is shortened relative to the outer guide tube, thereby realizing a small shortening adjustment of the riprap guide tube.

[0027] Furthermore, the method for using the riprap conduit uninterrupted feeding regulating device provided by the present invention further includes:

[0028] External catheter large adjustment mode:

[0029] Lock the platform base of the top sliding platform of the outer catheter lifting support frame on the two guide rails through the fixing parts, and keep the remaining platform bases slidingly set on the two guide rails;

[0030] The driving motor of the top sliding platform controls the driving gear connected to it to drive the slip ring to rotate relative to the platform base, so that the lock box and the lug of the hinge mechanism between the upper and lower sections of the outer tube are staggered by 90 degrees, opening the lifting window of the outer tube relative to the slip ring;

[0031] When the outer tube of the riprap guide tube needs to be extended, the hydraulic cylinder between the two uppermost sliding platforms is synchronously controlled to be in an extended state, so as to control the sliding platform below the top and the outer tube supported by it to sink as a whole, so that the uppermost section of the outer tube sinks relative to the upper sliding platform through the outer tube lifting window in the open state, so that the uppermost section of the outer tube sits on the ear piece of the upper sliding platform through the lock box at its upper end, while keeping the inner tube inserted in the outer tube, so that the outer tube of the riprap guide tube sinks one section as a whole;

[0032] Open the safety pin of the lock box on the top section of the external conduit, remove the block, splice the two half tubes of the newly added section of the external conduit onto the exposed inner conduit, install the trunnion at the lower end of the newly added section of the external conduit on the cradle base of the lock box in the open state, restore the installation of the block and safety pin, hinge the newly added section of the external conduit to the upper end of the sunken external conduit, complete the installation of one section of the external conduit, and update the newly added section of the external conduit to the top section of the external conduit;

[0034] In order to solve the above technical problems, the present invention further provides a riprap system, comprising:

[0035] Construction vessels, located in deep-water environments where rock dumping operations are to be carried out;

[0036] An uninterrupted feeding and regulating device for the riprap conduit is fixedly arranged on the construction vessel;

[0037] a riprap conduit, arranged on the riprap conduit uninterrupted feeding regulating device;

[0038] A feeding device is arranged on the construction vessel, and is aligned with the inner conduit of the riprap conduit.

[0039] In order to solve the above technical problems, the present invention further provides a riprap method, which uses the above riprap system and includes:

[0040] Normal construction mode:

[0041] The inner conduit of the riprap conduit is supported by the inner conduit support frame of the riprap conduit uninterrupted feeding and regulating device, and the outer conduit of the riprap conduit is supported by the outer conduit lifting support frame of the riprap conduit uninterrupted feeding and regulating device to be extended to the underwater seabed, so that the lower end of the outer conduit of the riprap conduit is kept at a constant height with the seabed, and riprap is continuously supplied to the inner conduit of the riprap conduit through the feeding device, so that the riprap is dropped through the riprap conduit to the seabed to form an underwater foundation;

[0042] External catheter small adjustment mode:

[0043] When the seabed topography changes and causes a slight increase in water depth, the outer conduit is sunk a certain distance according to the use of the riprap conduit's uninterrupted feeding and regulating device to maintain a constant height between the outer conduit and the seabed. During the sinking process of the outer conduit, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is released to the seabed through the riprap conduit with slight increase in depth to form an underwater foundation.

[0044] When the seabed topography changes and causes a slight decrease in the water depth, the outer conduit is raised a certain distance in the reverse manner of the operation of the riprap conduit's uninterrupted feeding adjustment device, maintaining a constant height between the outer conduit and the seabed. During the rising process of the outer conduit, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is released to the seabed through the slightly shortened riprap conduit to form an underwater foundation.

[0045] External catheter large adjustment mode:

[0046] When the seabed topography changes and causes the water depth to increase significantly, an outer pipe section is added to the outer pipe according to the method of using the uninterrupted feeding and regulating device of the riprap pipe to maintain a constant height between the outer pipe and the seabed. During the process of extending the outer pipe section, riprap is continuously supplied into the riprap pipe through the feeding device, so that the riprap is released to the seabed through the riprap pipe that has been significantly extended and regulated to form an underwater foundation.

[0047] When the seabed topography changes and causes the water depth to decrease significantly, a section of the outer duct is reduced on the outer duct in the opposite manner of the method of using the uninterrupted feeding and adjusting device of the riprap duct to maintain a constant height between the outer duct and the seabed. During the process of reducing one section of the outer duct, riprap is continuously supplied into the riprap duct through the feeding device, so that the riprap is dropped into the seabed through the drastically shortened and adjusted riprap duct to form an underwater foundation.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] The present invention provides a riprap conduit and an uninterrupted feeding and regulating device thereof, a method for using the same, a riprap system, and a riprap method. Two adjacent sections of the outer conduit are detachably connected via a hinge mechanism, which, on the one hand, ensures the reliability of the connection between the two adjacent sections of the outer conduit, and on the other hand, enables each section of the outer conduit to be detachably connected. Still further, the two adjacent sections of the outer conduit can swing axially at the hinge, so that during the riprap operation, the outer conduit can adapt to the unevenness of the seabed and the changes in the impact of the water flow, and has a certain degree of axial freedom of bending, thereby ensuring the accurate and uniform delivery of the riprap material, thereby improving the riprap quality and ensuring the construction quality of the underwater foundation.

[0050] The present invention provides a riprap guide tube and an uninterrupted feeding and adjusting device thereof, a method for using the same, a riprap system, and a riprap method. Under the condition of uninterrupted feeding, the length of the outer guide tube is dynamically adjusted so that the riprap guide tube maintains a constant height difference with the seabed, enabling continuous riprap operations, ensuring the thickness uniformity of the riprap layer of the underwater foundation, avoiding or reducing construction joints, thereby ensuring the construction quality of the underwater foundation, improving the construction efficiency of the riprap operation, not affecting the construction progress, avoiding the waste of the waiting window period during the adjustment of the outer guide tube, and having the advantage of a short construction period.

[0051] The present invention provides a riprap tube and an uninterrupted feeding adjustment device and a method for using the same, a riprap system and a riprap method, which dynamically adjust the length of the riprap tube through uninterrupted feeding in a deepwater environment, thereby avoiding the safety risk of sediment blockage caused by the need to interrupt feeding and adjust the riprap tube in a traditional riprap tube, and the operational risk caused by frequent disassembly and assembly of the outer tube in a deepwater environment.

The platform base 241 is also provided with a cylinder base 245 for mounting the hydraulic cylinder 222.

[0100] The bearing ring 243 of the platform assembly 240 can be replaced by a steel ring, the purpose of which is to raise the gear ring 252 to expose the slip ring 251 so as to achieve meshing connection between the driving gear 262 and the gear ring 252 .

[0101] The top sliding platform 221 is fixed on the two guide rails 210 by locking the slider 242 through the fixing part 211. At the same time, the fixing part 211 can be used as a connecting part fixed on the construction ship 40. The remaining sliding platforms 221 are slidably connected to the two guide rails 210 through the slider 242.

[0102] The driving motor 261 of each group of sliding platforms 221 controls the rotation of the slip ring 251 relative to the platform base 241 through the driving gear 262, and controls the ear piece 253 of the rotating assembly 250 to be supported on the lock box 132 of the outer catheter 120, that is, the sliding platform 221 supports the outer catheter 120 to bear its gravity, and at this time, the lifting window of the outer catheter 120 relative to the slip ring 251 is closed; or the ear piece 253 of the rotating assembly 250 is controlled to be staggered 90 degrees with the lock box 132 of the outer catheter 120 at the corresponding position, and at this time, the lifting window of the outer catheter 120 relative to the slip ring 251 is opened; at least one group of sliding platforms 221 is maintained on the lock box of the outer catheter 120 by its ear piece 253, that is, the sliding platform 221 bears the gravity of the outer catheter 120 to prevent the outer catheter 120 from falling off.

[0103] The hydraulic cylinder 222 is disposed between the two sets of sliding platforms 221. The hydraulic cylinder 222 is used to control the adjacent sliding platforms 221 to alternately support the outer conduit 120, thereby keeping the outer conduit 120 on the outer conduit lifting support frame 220 and preventing it from falling off and falling into the water.

[0104] Please refer to Figures 6 to 8 and Figure 10 The outer conduit lifting support frame 220 supports the outer conduit 120 via at least one set of sliding platforms 221. A hydraulic cylinder 222 allows the remaining sliding platforms 221 to be telescoped relative to the top sliding platform 221, thereby controlling the raising and lowering of the entire connected outer conduit 120. For ease of understanding, the figure illustrates four sliding platforms: a first sliding platform 221-1, a second sliding platform 221-2, a third sliding platform 221-3, and a fourth sliding platform 221-4. However, the number is not limited to four; two or more may suffice.

[0105] Please refer to Figures 6 and 7 The second embodiment of the present invention provides a riprap conduit uninterrupted feeding adjustment device 20, wherein the inner conduit support frame 230 includes a clamping frame 232 mounted on the two guide rails 210 via a connector 231. The clamping frame 232 is used to support the inner conduit 110 to prevent it from falling or tilting. The clamping frame 232 may be a ring frame, a U-shaped frame, or the like.

[0106] Please focus on Figures 1 to 14 、 Figure 26 The second embodiment of the present invention further provides a method for using the riprap conduit uninterrupted feeding adjustment device, comprising:

[0107] Step S501, initial installation of the riprap conduit 10, such as Figure 1 shown.

[0108] The outer tube 120 of the riprap tube 10 is supported by the outer tube lifting support frame 220, and the rotating platform is controlled by each group of driving components 260 to rotate relative to the platform component 240, so that the ear piece 253 is aligned with the lock box 132 of the outer tube 120, so that the lock box 132 of the hinge mechanism 130 at the connection between two adjacent sections of the outer tube 120 is located on the ear piece 253 of each group of sliding platforms 221, as shown in FIG. Figure 6 and Figure 10 shown.

[0109] Insert the inner conduit 110 of the riprap conduit 10 into the outer conduit 120, and support the inner conduit 110 of the riprap conduit 10 through the inner conduit support frame 230, that is, clamp the inner conduit 110 on the outer conduit 120 through the bell mouth at the upper end of the inner conduit 110. Figure 1 、 Figure 10 shown.

[0110] Step S502: The outer catheter 120 is in a small-amplitude adjustment mode:

[0111] The platform base 241 of the top sliding platform 221 of the outer catheter lifting support frame 220 is locked on the two guide rails 210 through the fixing piece 211, and the remaining platform bases 241 are kept slidingly set on the two guide rails 210, such as Figure 26 shown.

[0112] The driving motor 261 of the top sliding platform 221 controls the driving gear 262 connected thereto to drive the slip ring 251 to rotate relative to the platform base 241, so that the lock box 132 of the hinge mechanism 130 between the upper and lower sections of the outer tube 120 of the ear piece 253 is staggered by 90 degrees, thereby opening the lifting window of the outer tube 120 relative to the slip ring 251. The opening of the lifting window of the outer tube 120 relative to the slip ring 251 means that the outermost distance between the hinge mechanisms 130 is smaller than the inner diameter of the slip ring 251. When the ear piece 253 of the first sliding platform 221-1 and the lock box 132 of the hinge mechanism 130 of the outer tube 120 at its location are staggered by 90 degrees, the hinge mechanism 130 can pass through the inner diameter of the slip ring 251 of the rotating assembly 250 of the first sliding platform 221-1, as shown in FIG. Figure 26 shown.

[0113] When it is necessary to control the growth and adjustment of the riprap guide tube 10, the hydraulic cylinder 222 between the two uppermost sliding platforms 221 is synchronously controlled to be in an extended state, so as to control the sliding platform 221 below the top and the outer guide tube 120 supported by it to sink as a whole. The lifting window of the outer guide tube 120 in the open state is sunk a certain distance relative to the top sliding platform 221 as a whole, so that the inner guide tube 110 is extended relative to the sunken outer guide tube 120 without being separated, thereby achieving a small growth adjustment of the riprap guide tube 10.

[0114] When the shortening adjustment of the riprap guide tube 10 is required, the hydraulic cylinder 222 between the two uppermost sliding platforms 221 is synchronously controlled to be in a retracted state, so as to control the sliding platform 221 below the top and the outer guide tube 120 supported by it to rise as a whole for a certain distance, so that the inner guide tube 110 is shortened relative to the raised outer guide tube 120, thereby achieving a small shortening adjustment of the riprap guide tube 10.

[0115] The length adjustment relationship of the outer conduit 120 needs to take into account the initial installation state of the riprap conduit 10. If the initial installation state is Figure 26 When the inner catheter 110 is fully inserted into the outer catheter 120 as shown in the left figure, the sequence of first lengthening and then shortening is followed; if the initial installation state is as shown in the right figure, the inner catheter 110 is not fully inserted into the outer catheter 120, the sequence of first shortening and then lengthening is followed.

[0116] The uninterrupted feeding adjustment device for the riprap tube and the method for using the same provided in the second embodiment of the present invention can, through the above-mentioned adjustment relationship, adjust the outer tube 120 of the riprap tube 10 to rise or fall slightly, so as to adapt to the change in the height difference between the outer tube 120 and the seabed caused by the change in water depth due to the change in the seabed topography, ensure that the height difference between the outer tube 120 and the seabed is at a constant height, control the thickness uniformity of the riprap layer formed on the seabed by the riprap material, avoid the occurrence of step differences in the riprap material, and improve the construction quality of the underwater foundation; the uninterrupted feeding adjustment device for the riprap tube and the method for using the same provided in the second embodiment of the present invention can, through the above-mentioned adjustment relationship, ensure the continuous feeding of the riprap tube 10, avoid interruption, and avoid the riprap tube 10 being blocked by the riprap material, and have the advantage of high safety.

[0117] Please refer to Figures 10 to 25 The riprap conduit uninterrupted feeding adjustment device and its use method provided in the second embodiment of the present invention further include:

[0118] Step S503, the outer catheter 120 is adjusted in a large range:

[0119] First, the platform base 241 of the top sliding platform 221 of the outer catheter lifting support frame 220 is locked on the two guide rails 210 through the fixing piece 211, and the remaining platform base 241 is kept slidingly set on the two guide rails 210, as shown in FIG. Figures 11 to 12 shown.

[0120] Secondly, the driving motor 261 of the top sliding platform 221 controls the driving gear 262 connected thereto to drive the slip ring 251 to rotate relative to the platform base 241, so that the ear piece 253 thereof and the lock box 132 of the hinge mechanism 130 between the upper and lower sections of the outer tube 120 are staggered by 90 degrees, thereby opening the lifting window of the outer tube 120 relative to the slip ring 251, as shown in FIG. Figures 13 and 14 The top sliding platform 221 is the first sliding platform 221-1.

[0121] Then, when it is necessary to control the extension of the outer tube 120 of the riprap tube 10, the hydraulic cylinder 222 between the two uppermost sliding platforms 221 is synchronously controlled to be in an extended state to control the sliding platform 221 below the top and the outer tube 120 supported by it to sink as a whole. The lifting window of the outer tube 120 in the open state is lowered as a whole relative to the top sliding platform 221, so that the upper end of the uppermost section of the outer tube 120 is sunk to the top sliding platform 221, and the uppermost section of the outer tube 120 is placed on the ear piece 253 of the top sliding platform 221 through the lock box 132 at its upper end. At the same time, the inner tube 110 is kept inserted into the outer tube 120, so that the outer tube 120 of the riprap tube 10 is sunk one section as a whole for a large adjustment, such as Figures 15 and 16 shown.

[0122] Afterwards, open the safety pin 132-3 of the lock box 132 on the top outer conduit 120, take out the stopper 132-2, splice the two half tubes 121 of the newly added outer conduit 120 on the exposed inner conduit 110, install the ear shaft 131 at the lower end of the newly added outer conduit 120 on the cradle base 132-1 of the lock box 132 in the open state, restore the installation of the stopper 132-2 and the safety pin 132-3, so that the newly added outer conduit 120 is hinged to the upper end of the sunken outer conduit 120, realize the extension installation of one outer conduit 120, and update the newly added outer conduit 120 to the top outer conduit 120. Figures 17 to 23 shown.

[0123] Finally, the top sliding platform 221 is kept supporting the entire outer tube 120, and the driving motors 261 of the sliding platforms 221 below the top are controlled in turn to control the driving gears 262 connected thereto to drive the slip ring 251 to rotate relative to the platform base 241, so that the ear pieces 253 of the sliding platforms 221 below the top are staggered 90 degrees from the lock boxes 132 of the outer tube 120, and the support of the remaining sliding platforms 221 and the outer tube 120 is released, and the lifting windows of the outer tube 120 at each sliding platform 221 are opened. The sliding platforms 221 below the top are restored to their initial installation positions between the two guide rails 210 by controlling the extension and contraction of the hydraulic cylinders 222, as shown in FIG. Figure 24 When the outer guide tube lifting support frame 220 is composed of two sliding platforms 221 and a set of hydraulic cylinders 222 therebetween, the top sliding platform 221 is kept fixed on the two guide rails 210, and the second sliding platform 221 is reset to the initial installation position of the two guide rails 210 by retracting the hydraulic cylinders 222.

[0124] Please refer to Figure 24 and Figure 25 When the outer tube lifting support frame 220 comprises four sliding platforms 221 and three sets of hydraulic cylinders 222 between two adjacent sliding platforms 221, the first set of hydraulic cylinders 222 between the first sliding platform 221-1 and the second sliding platform 221-2 is retracted, and the second hydraulic cylinder 222 between the second sliding platform 221-2 and the third sliding platform 221-3 is extended, so that the second sliding platform 221-2 is reset on the two guide rails 210; the second set of hydraulic cylinders 222 between the second sliding platform 221-2 and the third sliding platform 221-3 is retracted, and the third hydraulic cylinder 222 between the third sliding platform 221-3 and the fourth sliding platform 221-4 is extended, so that the third sliding platform 221-3 is reset; and the third set of hydraulic cylinders 222 between the third sliding platform 221-3 and the fourth sliding platform 221-4 is retracted, so that the fourth sliding platform 221-4 is reset. Each set of hydraulic cylinders 222 includes but is not limited to two symmetrically distributed ones.

[0125] The large-scale adjustment mode and small-scale adjustment mode of the outer conduit 120 are adaptively adjusted according to changes in water depth, and there is no specific order of precedence. In the large-scale adjustment mode of the outer conduit 120, the sliding platform 221 alternately controls the load-bearing relationship of the outer conduit 120 and the expansion and contraction of the hydraulic cylinder 222, allowing the outer conduit 120 to be dynamically extended or shortened without sinking, ensuring the continuity of the riprap operation and improving the quality and efficiency of the riprap operation.

[0126] Step S503 specifically describes the process of installing the outer conduit 120 by significantly adjusting and adding sections. The reverse process can be followed by the process of removing the outer conduit 120 by significantly adjusting and reducing sections. This process also facilitates the removal of the riprap conduit 10 after the riprap operation, eliminating the need for constant adjustment of the slings required to connect and disconnect different sections of the outer conduit 120 as in traditional slinging methods. This makes removal easier, safer, and simpler.

[0127] The second embodiment above details the process of adding one section of outer conduit using the riprap conduit continuous feeding and regulating device and its method of use. As the water depth continues to increase, the device and method can be used to add at least one more section of outer conduit. As the water depth decreases, the reverse of the above method can be used to remove one section of outer conduit.

[0130] The construction vessel 40 is located in a deep water environment where rock dumping operations are to be performed.

[0131] The riprap conduit uninterrupted feeding adjustment device 20 is fixedly installed on the construction ship 40.

[0132] The riprap conduit 10 is provided on the riprap conduit uninterrupted feeding regulating device 20 .

[0133] A feeding device 30 is provided on the construction vessel 40, aligned with the inner conduit 110 of the riprap conduit 10. The feeding device 30 may be a conveyor belt or a conveyor pipe.

[0134] Please focus on Figure 10 The third embodiment of the present invention further provides a riprap method, comprising:

[0135] Normal construction mode:

[0136] The inner conduit 110 of the riprap conduit 10 is supported by the inner conduit support frame 230 of the riprap conduit uninterrupted feeding and regulating device 20, and the outer conduit 120 of the riprap conduit 10 is supported and extended to the underwater seabed by the outer conduit lifting support frame 220 of the riprap conduit uninterrupted feeding and regulating device 20, so as to maintain a constant height between the lower end of the outer conduit 120 of the riprap conduit 10 and the seabed, and riprap is continuously supplied to the inner conduit 110 of the riprap conduit 10 through the feeding device 30, so that the riprap is dropped through the riprap conduit 10 to the seabed to form an underwater foundation.

[0137] Outer catheter 120 small adjustment mode:

[0138] When the seabed topography changes and causes a slight increase in water depth, the outer conduit 120 is sunk a certain distance according to the method of using the riprap conduit uninterrupted feeding and adjusting device 20 of the second embodiment to maintain a constant height between the outer conduit 120 and the seabed. During the sinking process of the outer conduit 120, riprap is continuously supplied into the riprap conduit 10 through the feeding device 30, so that the riprap is dropped to the seabed through the riprap conduit 10 with slight increase in adjustment to form an underwater foundation.

[0139] When the seabed topography changes and causes the water depth to decrease slightly, the outer conduit 120 is raised a certain distance in the opposite manner of the method of using the riprap conduit uninterrupted feeding adjustment device of Example 2 to maintain a constant height between the outer conduit 120 and the seabed. During the rising process of the outer conduit 120, riprap is continuously supplied into the riprap conduit 10 through the feeding device 30, so that the riprap is dropped onto the seabed through the slightly shortened riprap conduit 10 to form an underwater foundation.

[0140] Outer tube 120 large adjustment mode:

[0141] When the seabed topography changes and causes the water depth to increase significantly, according to the method of using the riprap conduit uninterrupted feeding and adjusting device of Example 2, an outer conduit section 120 is added to the outer conduit 120 to maintain a constant height between the outer conduit 120 and the seabed. During the process of extending the outer conduit section 120, riprap is continuously supplied into the riprap conduit 10 through the feeding device 30, so that the riprap is dropped to the seabed through the riprap conduit 10 that has been significantly lengthened and adjusted to form an underwater foundation.

[0142] When the seabed topography changes and causes the water depth to decrease significantly, one section of the outer conduit 120 is reduced on the outer conduit 120 in the opposite manner of the method of using the uninterrupted feeding and adjusting device for the riprap conduit of Example 2 to maintain a constant height between the outer conduit 120 and the seabed. During the process of reducing one section of the outer conduit 120, the feeding device 30 continuously supplies riprap into the riprap conduit 10, so that the riprap is dropped onto the seabed through the riprap conduit 10 that has been significantly shortened and adjusted to form an underwater foundation.

[0143] The riprap conduit and its uninterrupted feeding and adjusting device and method of use, riprap system and riprap method provided by the above-mentioned embodiments of the present invention dynamically adjust the length of the outer conduit 120 under the condition of uninterrupted feeding, so that the riprap conduit 10 maintains a constant height difference with the seabed, enabling the riprap operation to be carried out continuously, ensuring the thickness uniformity of the riprap layer of the underwater foundation, avoiding or reducing construction joints, thereby ensuring the construction quality of the underwater foundation, improving the construction efficiency of the riprap operation, not affecting the construction progress, shortening the construction period of the riprap operation, ensuring the thickness uniformity of the riprap layer of the underwater foundation, avoiding or reducing construction joints, thereby ensuring the construction quality of the underwater foundation, avoiding the waste of the waiting window period during the adjustment process of the outer conduit 120, and having the advantage of a short construction period.

[0144] The present invention provides a riprap tube and an uninterrupted feeding adjustment device and a method for using the same, a riprap system and a riprap method. By dynamically adjusting the length of the riprap tube 10 through uninterrupted feeding in a deepwater environment, the length of the riprap tube 10 is adjusted, thereby avoiding the safety risk of sediment blockage caused by the need to interrupt feeding to adjust the riprap tube in a traditional riprap tube and the operational risk caused by frequent disassembly and assembly of the outer tube in a deepwater environment.

[0145] The above-mentioned embodiments of the present invention provide a riprap conduit, an uninterrupted feeding and regulating device thereof, a method of use thereof, a riprap system, and a riprap method. In the riprap conduit 10, the outer conduit 120 that does not cover the inner conduit 110 can swing and bend through a hinge mechanism 130 to adapt to the unevenness of the seabed and changes in water flow impact, thereby ensuring the accurate and uniform delivery of riprap materials and improving the construction quality of the underwater foundation.

[0146] The riprap conduit and its uninterrupted feeding adjustment device and use method, riprap system and riprap method provided in the above-mentioned embodiments of the present invention solve the technical problem that the traditional riprap conduit must interrupt the feeding to interrupt the riprap operation when adjusting the riprap conduit. It has the advantages of continuous operation, flexible adaptability, construction safety, quality assurance and convenient operation. It is suitable for construction projects with underwater foundations constructed in deep water riprap operations such as offshore wind power foundation protection, submarine pipeline stabilization and cable protection.

[0147] The riprap conduit and its uninterrupted feeding and adjusting device and its use method, riprap system and riprap method provided in the above-mentioned embodiment of the present invention realize dynamic lifting and lowering adjustment of the outer conduit 120 while continuously supplying riprap materials, by alternately supporting the outer conduit 120 through each group of sliding platforms 221 of the outer conduit lifting support frame 220 of the uninterrupted feeding and adjusting device 20 of the riprap conduit, and cooperating with the relative telescopic control of the sliding platforms 221 by the hydraulic cylinder 222, so as to ensure that the lower end of the outer conduit 120 is at a constant height difference with the seabed.

[0148] The above-mentioned embodiments of the present invention provide a riprap conduit, an uninterrupted feeding and regulating device thereof, a method of using the riprap system, and a riprap method. The riprap material passes through the riprap conduit continuously and uninterruptedly. The outer conduit can flexibly swing and bend to adapt to changes in seabed topography through a hinge mechanism. The hinge mechanism can also prevent the upper and lower sections of the outer conduit from loosening to ensure construction safety. The inner conduit always wraps the riprap material to avoid overflow or deposition of the riprap material during the disassembly and assembly process, ensuring that the riprap layer is continuous and uniform without construction joints, thereby improving the overall structural stability of the underwater foundation and ensuring the construction quality of the underwater foundation. The outer conduit is alternately supported by multiple sliding platforms, which has the advantage of convenient operation for adjusting the length of the riprap conduit and is suitable for efficient riprap operations in complex sea conditions.

Open the safety pin of the lock box on the top section of the external conduit, remove the block, splice the two half tubes of the newly added section of the external conduit onto the exposed inner conduit, install the trunnion at the lower end of the newly added section of the external conduit on the cradle base of the lock box in the open state, restore the installation of the block and safety pin, hinge the newly added section of the external conduit to the upper end of the sunken external conduit, complete the installation of one section of the external conduit, and update the newly added section of the external conduit to the top section of the external conduit; Keep the top sliding platform supporting the entire outer tube, and control the drive motors of each sliding platform below the top in turn to control the connected drive gears to drive the slip ring to rotate relative to the platform base, so that the ear pieces of the sliding platform below the top and the lock boxes of the outer tube are staggered 90 degrees, release the support of the remaining sliding platforms and the outer tube, open the outer tube lifting windows at each sliding platform, and restore the sliding platform below the top to its initial installation position between the two guide rails through the telescopic control of the hydraulic cylinder.

6. A riprap system, characterized in that: include: Construction vessels, located in deep-water environments where rock dumping operations are to be carried out; The riprap conduit uninterrupted feeding and regulating device is fixedly mounted on the construction vessel and is the riprap conduit uninterrupted feeding and regulating device according to claim 2; a riprap conduit, provided on the riprap conduit uninterrupted feeding regulating device, and being the riprap conduit according to claim 1; A feeding device is arranged on the construction vessel, and is aligned with the inner conduit of the riprap conduit.

7. A method for throwing stones, characterized in that: The riprap system of claim 6, comprising: Normal construction mode: The inner conduit of the riprap conduit is supported by the inner conduit support frame of the riprap conduit uninterrupted feeding and regulating device, and the outer conduit of the riprap conduit is supported by the outer conduit lifting support frame of the riprap conduit uninterrupted feeding and regulating device to be extended to the underwater seabed, so that the lower end of the outer conduit of the riprap conduit is kept at a constant height with the seabed, and riprap is continuously supplied to the inner conduit of the riprap conduit through the feeding device, so that the riprap is dropped through the riprap conduit to the seabed to form an underwater foundation; External catheter small adjustment mode: When the seabed topography changes and causes a slight increase in water depth, the outer conduit is sunk a certain distance according to the method for using the uninterrupted feeding and regulating device for the riprap conduit according to claim 4, so as to maintain a constant height between the outer conduit and the seabed. During the sinking process of the outer conduit, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is dropped to the seabed through the riprap conduit with slight increase in water depth to form an underwater foundation. When the seabed topography changes and causes a slight decrease in the water depth, the outer conduit is raised a certain distance in the reverse manner of the method for using the uninterrupted feeding and regulating device for the riprap conduit according to claim 4, so as to maintain a constant height between the outer conduit and the seabed. During the raising process of the outer conduit, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is dropped onto the seabed through the slightly shortened riprap conduit to form an underwater foundation. External catheter large adjustment mode: When the seabed topography changes and causes the water depth to increase significantly, an outer conduit section is added to the outer conduit according to the method for using the uninterrupted feeding and regulating device for the riprap conduit of claim 5 to maintain a constant height between the outer conduit and the seabed. During the process of extending the outer conduit section, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is released to the seabed through the riprap conduit that has been significantly lengthened and regulated to form an underwater foundation. When the seabed topography changes and causes the water depth to decrease significantly, a section of the outer conduit is reduced on the outer conduit in the opposite manner of the method of using the uninterrupted feeding and adjusting device for the riprap conduit according to claim 5 to maintain a constant height between the outer conduit and the seabed. During the process of reducing one section of the outer conduit, riprap is continuously supplied into the riprap conduit through the feeding device, so that the riprap is dropped onto the seabed through the riprap conduit that has been significantly shortened and adjusted to form an underwater foundation.
