Description

Technical Field

[0001] The present invention relates to the technical field of underwater foundation construction of marine engineering, and in particular to a Hough-type riprap pipe, an uninterrupted feeding riprap device and a method. Background Art

[0002] Currently, deepwater riprap operations, such as those in marine engineering, are commonly carried out using riprap pipes. During riprap operations, varying water depths due to changing seabed topography necessitate real-time adjustment of the pipe length to ensure a constant height between the pipe's lower outlet and the seabed. However, when lengthening or shortening the pipe, the riprap feed must be interrupted, and work can only resume after the pipe has been adjusted. This approach presents several drawbacks: Each riprap pipe length adjustment requires a long construction period, resulting in prolonged interruptions (typically exceeding 30 minutes) in the riprap operation, severely impacting efficiency and progress, and extending the construction period. Frequent riprap pipe length adjustments also interrupt the riprap feed, leading to uneven control of the riprap layer thickness and the formation of noticeable joints, impacting the construction quality and structural stability of the underwater foundation. Frequent riprap pipe length adjustments in deepwater environments increase operational risks, posing a safety risk of riprap material clogging the pipe during feed interruptions. Summary of the Invention

[0003] The purpose of the present invention is to provide a Hough type riprap pipe, an uninterrupted feeding riprap device and a method to solve the problems of interruption of feeding in the riprap pipe for length adjustment affecting the riprap operation efficiency, progress, project period, underwater foundation quality, and the safety risk of blockage in the riprap pipe.

[0004] In order to solve the above technical problems, the present invention provides a Hough-type riprap guide tube, comprising an outer sleeve, an inner sleeve inserted into the outer sleeve, a filling port being provided at the upper end of the inner sleeve, the outer sleeve being composed of multiple sections, each section of the outer sleeve being a Hough-type outer sleeve composed of a front Hough tube and a rear Hough tube detachably connected by a locking mechanism, and two adjacent sections of the Hough-type outer sleeve being detachably connected by at least one of two groups of connecting mechanisms distributed crosswise.

[0005] Furthermore, in the Hough-type riprap catheter provided by the present invention, each group of the connecting mechanisms includes two radially evenly distributed rings hinged on the upper end of the outer sleeve of the lower section, and two radially evenly distributed pins hinged on the lower end of the outer sleeve of the upper section, and a ring between two adjacent upper and lower sections of the outer sleeve is correspondingly fastened to one of the pins.

[0006] Furthermore, in the Half-type riprap guide tube provided by the present invention, the lifting ring includes a hinged seat and a T-shaped rod connected to the hinged seat, and the T-shaped rod is connected to a circular ring on the rod body along the axial direction of the outer sleeve; the buckle includes a stud vertically arranged on the outer sleeve, and a buckle cap threadedly connected to the stud; the buckle cap is located on the outside of the circular ring.

[0007] Furthermore, the locking mechanism of the half-type riprap guide tube provided by the present invention includes at least two spaced-apart ear plates arranged at corresponding positions on the front half tube and the rear half tube, and bolts passing through the ear plates of the front half tube and the ear plates of the rear half tube to connect the two half tubes into one section of the outer sleeve.

[0008] Furthermore, in the Hough type riprap catheter provided by the present invention, the cross-sections of the front and rear Hough tubes of each section of the outer sleeve are in the shape of three steps that are matched and spliced ​​with each other.

[0009] Furthermore, in the half-pipe riprap conduit provided by the present invention, the cross-sectional shape of the front half-pipe includes, from top to bottom, a first half-pipe segment larger than 1 / 2 circle, a second half-pipe segment equal to 1 / 2 circle, and a third half-pipe segment smaller than 1 / 2 circle; the cross-sectional shape of the rear half-pipe includes a fourth half-pipe segment smaller than 1 / 2 circle, a fifth half-pipe segment equal to 1 / 2 circle, and a sixth half-pipe segment larger than 1 / 2 circle.

[0010] In order to solve the above technical problems, the present invention also provides a Hough type uninterrupted feeding stone throwing device, comprising:

[0011] A fixed frame, set on a work boat;

[0012] a suspension rope connected to the fixed frame;

[0013] The riprap conduit is the aforementioned Hough-type riprap conduit, wherein the outer sleeve of the Hough-type riprap conduit has a lifting ring connected to the lifting rope, and the outer sleeve is suspended by the lifting rope and deeply lowered to the seabed underwater;

[0014] The conveyor belt is aligned with the riprap guide tube and is arranged on the work vessel.

[0015] In order to solve the above technical problems, the present invention further provides a Hough type uninterrupted feeding and riprap method, which adopts the above-mentioned Hough type uninterrupted feeding and riprap device, comprising:

[0016] Normal construction mode:

[0017] The outer sleeve of the riprap pipe is hoisted to the underwater seabed by a lifting rope, and the lower end of the outer sleeve of the riprap pipe is kept at a constant height from the seabed. The riprap material is supplied to the riprap pipe by a conveyor belt, so that the riprap material is dropped to the seabed through the riprap pipe to form an underwater foundation;

[0018] Water depth change fine-tuning mode:

[0019] When the seabed topography changes and causes a slight increase in water depth, the outer casing is lowered by adjusting the lifting rope to maintain a constant height above the seabed, the inner casing is pulled up and kept inside the outer casing, and riprap is continuously supplied to the riprap pipe through the conveyor belt, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation;

[0020] When the seabed topography changes and causes a slight decrease in water depth, the outer casing is raised by adjusting the lifting rope to maintain a constant height above the seabed, and the inner casing is lowered and kept inside the outer casing. The conveyor belt is used to continuously supply riprap to the riprap pipe, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation.

[0021] Water depth change coarse adjustment mode:

[0022] When the seabed topography changes and causes the water depth to increase significantly, the outer casing is lowered by adjusting the lifting rope, and the inner casing is pulled up to keep it inside the outer casing. The conveyor belt is used to continuously supply riprap to the riprap pipe, and its height with the seabed is kept constant, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation.

[0023] The two lifting ropes connected to the relatively distributed lifting rings of the uppermost outer sleeve are respectively connected to the lifting rings of a new front half pipe and a new rear half pipe. The newly added front and rear half pipes are hoisted on both sides of the removed inner sleeve and connected by a locking mechanism to form an outer sleeve of the newly added section. The outer sleeve of the newly added section wraps around the removed inner sleeve. The lifting ropes maintain the hoisting of the outer sleeve of the newly added section and the outer sleeve of the lower section. The outer sleeve of the newly added section and the outer sleeve of the lower section are connected by at least one set of connecting mechanisms.

[0024] Remove the remaining two lifting ropes from the lifting rings of the lower outer sleeve below the newly added section and replace them with the two lifting ropes that are not connected to the lifting ropes on the newly added section outer sleeve. Lift the entire outer sleeve and at the same time buckle the lifting rings of another set of connecting mechanisms of the outer sleeve of the newly added section and the outer sleeve of the lower section onto the buckle nails.

[0025] Furthermore, the Hough-type continuous feeding riprap method provided by the present invention is such that when the seabed topography changes and the water depth decreases significantly, the outer casing of the uppermost section is removed in the reverse manner described above, and the inner casing is lowered, and riprap is continuously fed through the riprap pipe and released onto the seabed to form an underwater foundation;

[0026] Furthermore, the Hough-type uninterrupted feeding and riprap method provided by the present invention forms a flexibly connected outer casing through a set of connecting mechanisms between each section of the outer casing, so that adjacent outer casings not wrapped with the inner casing can swing and bend to adapt to the unevenness of the seabed and changes in water flow impact, thereby ensuring the accurate and uniform delivery of riprap materials.

[0027] Compared with the prior art, the Hough-type riprap conduit, uninterrupted riprap feeding device and method provided by the present invention have the following beneficial effects:

[0028] The half-type riprap conduit composed of nested outer and inner casings can, on the one hand, adjust the depth of the inner casing inserted into the outer casing, thereby adjusting the length of the half-type riprap conduit; on the other hand, the length of the half-type riprap conduit can be adjusted by increasing the number of sections of the outer casing to adapt to changes in seabed topography and water depth, maintain a constant height between the lower end of the half-type riprap conduit and the seabed, and realize uninterrupted supply of riprap materials to the seabed through the half-type riprap conduit for constructing underwater foundations.

[0029] When constructing an underwater foundation using the riprap method, when changes in the seabed topography cause changes in the water depth, the depth of the inner casing inserted into the outer casing is adjusted, and the number of sections of the outer casing is increased or decreased, thereby maintaining a constant height between the Hough riprap pipe and the seabed, thereby continuously supplying riprap materials to the seabed through the Hough riprap pipe to form an underwater foundation.

[0030] Under the condition of uninterrupted material supply, the number of outer casing sections is increased or decreased to keep the Half-type riprap pipe at a constant height difference with the seabed. This allows the riprap operation to continue without affecting the construction efficiency, progress and construction period. It ensures the uniformity of the riprap layer thickness of the underwater foundation, avoids or reduces construction joints, and thus ensures the construction quality and structural strength of the underwater foundation. It has the advantages of high underwater foundation construction efficiency, short construction period and high construction quality.

[0031] By frequently adjusting the length of the Hough riprap tube during uninterrupted feeding in a deepwater environment, the Hough riprap tube can be used continuously, thus avoiding the safety risk of sedimentation and blockage in traditional riprap tubes during intermittent feeding and eliminating the safety hazard of pipe blockage.

[0049] The present invention will be described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0050] Example 1

[0051] Please refer to Figures 1 to 5A first embodiment of the present invention provides a half-type riprap guide tube 300, comprising an outer sleeve 310 and an inner sleeve 320 inserted within the outer sleeve 310. A filling port 321 is provided at the upper end of the inner sleeve 320. The outer sleeve 310 is multi-sectioned, each section comprising a half-type outer sleeve consisting of a front half-tube 311 and a rear half-tube 312 detachably connected via a locking mechanism 313. Adjacent half-type outer sleeves 310 are detachably connected via at least one of two cross-distributed connecting mechanisms 314. The inner sleeve 310 can be secured to the outer sleeve 310 via its filling port 321. To facilitate loading of riprap, the filling port 321 can be in a conical cylindrical shape, such as a truncated cone or a square cone.

[0052] The half-type riprap pipe 300 provided in the first embodiment of the present invention is composed of a nested and telescopic outer sleeve 310 and an inner sleeve 320. On the one hand, the depth of the inner sleeve 320 inserted into the outer sleeve 310 can be adjusted to adjust the length of the half-type riprap pipe 300. On the other hand, the length of the half-type riprap pipe 300 can be adjusted by increasing the number of sections of the outer sleeve to adapt to changes in seabed topography and water depth, maintain a constant height between the lower end of the half-type riprap pipe 300 and the seabed, and realize uninterrupted supply of riprap materials to the seabed through the half-type riprap pipe 300 for underwater foundation construction.

[0053] Please refer to Figures 2 to 4 To achieve a rigid or flexible connection between two adjacent outer sleeve sections 310, the Hough riprap catheter 300 provided in Example 1 of the present invention comprises two radially evenly spaced rings 314-1 hinged to the upper end of the lower outer sleeve section 310, and two radially evenly spaced studs 314-2 hinged to the lower end of the upper outer sleeve section 310. Each ring 314-1 between two adjacent outer sleeve sections 310 is latched onto one of the studs 314-2. The two sets of connection mechanisms 314 include four rings 314-1 and four studs 314-2 spaced at 90 degrees, with each ring 314-1 and stud 314-2 corresponding to each other in a straight line. When two adjacent sections of outer casing 310 are connected by both sets of connecting mechanisms 314, the connection between the two adjacent sections of outer casing 310 is a rigid connection. At this time, the half-type outer casing 310 is straight and deep in the underwater environment; when two adjacent sections of outer casing 310 are connected by one of the two sets of connecting mechanisms 314, the connection between the two adjacent sections of outer casing 310 is a flexible connection. It has a certain degree of freedom to adjust in the axial direction, and can be bent to introduce riprap to adapt to the unevenness of the seabed and the impact of water flow, ensuring the accuracy and uniformity of riprap.

[0054] Please refer to Figures 3 and 4In order to achieve swing adjustment of the axial freedom of the flexible connection between two adjacent sections of the outer sleeve 310, the half-type riprap guide tube 300 provided in the first embodiment of the present invention has the following structure: the lifting ring 314-1 includes a hinge seat 314-1a, a T-shaped rod 314-1b connected to the hinge seat 314-1a, and a ring 314-1c connected to the rod body of the T-shaped rod 314-1b along the axial direction of the outer sleeve 310; the buckle 314-2 includes a stud 314-2a vertically arranged on the outer sleeve 310, and a buckle cap 314-2b threadedly connected to the stud 314-2a; when the lifting ring 314-1 is connected to the T-shaped rod 314-1b, the lifting ring 314-1a is connected to the T-shaped rod 314-1b. When the transverse rod of the profiled rod 314-1b rotates about the hinge seat 314-1a so that the ring 314-1c is fastened to the peg 314-2a of the peg 314-2, the cap 314-2b is positioned outside the ring 314-1c. Thus, when only one set of connecting mechanisms 314 is connected, the cap 314-2b limits the ring 314-1c of the lifting ring 314-1, preventing the connecting mechanisms 314 from disengaging and causing the two adjacent sections of the outer sleeve 310 to disconnect. In this case, the ring 314-1c of the connecting mechanism 314 can rotate about the peg 314-2a, thereby creating axial freedom of adjustment between the two adjacent sections of the outer sleeve 310. The hinge seat 314-1a may be two parallel, spaced-apart ear plates with through holes welded to the outer sleeve 310.

[0055] Please focus on Figures 2 to 4 To facilitate assembly and disassembly of the outer sleeve 310 relative to the inner sleeve 320, the half-tube riprap guide tube 300 provided in the first embodiment of the present invention comprises a locking mechanism 313 comprising at least two spaced-apart lugs 313-1 disposed at corresponding positions on the front half tube 311 and the rear half tube 312. Bolts 313-2 penetrate the lugs 313-1 of the front half tube 311 and the rear half tube 312, connecting the two half tubes into a single section of the outer sleeve 310. The removable connection between the front half tube 311 and the rear half tube 312 via the locking mechanism 313 enables assembly and detachment of the outer sleeve 310.

[0056] Please focus on Figure 3To achieve staggered, flexible swinging of two adjacent outer casing sections 310, the half-pipe riprap guide tube 300 provided in the first embodiment of the present invention features a three-section stepped cross-section of the front and rear half-pipes 312 of each outer casing section 310. The cross-section of the front half-pipe 311, from top to bottom, comprises a first half-segment 311a greater than 1 / 2 circle, a second half-segment 311b equal to 1 / 2 circle, and a third half-segment 311c less than 1 / 2 circle. The cross-section of the rear half-pipe 312 comprises a fourth half-segment 312d less than 1 / 2 circle, a fifth half-segment 312e equal to 1 / 2 circle, and a sixth half-segment 312f greater than 1 / 2 circle. By selecting connecting mechanisms 314 on different opposite sides to connect two adjacent outer casing sections 310, the connecting mechanisms 314 between the two adjacent outer casing sections 310 are staggered, enabling flexible swinging of the three adjacent outer casing sections 310 in both directions. The front half pipe 311 and the rear half pipe 312 arranged in a three-stage stepped shape are both eccentric gravity structures, which facilitates the lifting, removal and separation of the front half pipe 311 and the rear half pipe 312.

[0057] Please refer to Figure 3 In the Hough riprap guide tube 300 provided in the first embodiment of the present invention, the locking mechanism 313 includes three rings 314-1 on the first half section 311a of the front half tube 311 of the lower outer tube 310, and one ring 314-1 on the fourth half section 312d of the rear half tube 312 of the lower outer tube 310. Furthermore, a pin 314-2 is provided on the third half section 311c of the front half tube 311 of the upper outer tube 310, and three pins 314-2 are provided on the sixth half section 312f of the rear half tube 312 of the upper outer tube 310. To ensure the secure connection of the outer tube sections 310, lugs 313-1 are provided on the second half section 311b and the fifth half section 312e, respectively.

The riprap material is supplied to the riprap tube 300 by the conveyor belt 400, so that the riprap material is dropped to the seabed through the riprap tube 300 to form an underwater foundation.

[0067] Water depth change fine-tuning mode:

[0068] Please refer to Figure 1 、 Figure 5 and Figure 6 When the seabed topography changes and causes the water depth to increase slightly, the outer sleeve 310 is lowered by adjusting the lifting rope 200 to maintain a constant height above the seabed, the inner sleeve 320 is pulled up and kept inside the outer sleeve 310, and the riprap is continuously supplied to the riprap pipe 300 through the conveyor belt 400, so that the riprap is dropped to the seabed through the riprap pipe 300 to form an underwater foundation; when the seabed topography changes and causes the water depth to decrease slightly, the outer sleeve 310 is raised by adjusting the lifting rope 200 to maintain a constant height above the seabed, the inner sleeve 320 is lowered and kept inside the outer sleeve 310, and the riprap is continuously supplied to the riprap pipe 300 through the conveyor belt 400, so that the riprap is dropped to the seabed through the riprap pipe 300 to form an underwater foundation.

[0069] Water depth change coarse adjustment mode:

[0070] Step S1, please refer to Figures 5 and 6 When the seabed topography changes and causes the water depth to increase significantly, the outer casing 310 is lowered by adjusting the suspension rope 200, and the inner casing 320 is pulled up to remain in the outer casing 310. The riprap is continuously supplied to the riprap pipe 300 through the conveyor belt 400, and its height with the seabed is maintained, so that the riprap is dropped onto the seabed through the riprap pipe 300 to form an underwater foundation.

[0071] Step S2, please refer to Figures 6 to 11, release the two lifting ropes 200 connected to the relatively distributed lifting rings 314-1 of the uppermost outer sleeve 310 and connect them to the lifting rings 314-1 of a new front half tube 311 and a rear half tube 312 respectively, and hang the newly added front and rear half tubes 312 on both sides of the pulled out inner sleeve 320 and connect them through the locking mechanism 313 to form a newly added section of outer sleeve 310, so that the newly added section of outer sleeve 310 wraps the pulled out inner sleeve 320, and the lifting of the newly added section of outer sleeve 310 and the outer sleeve 310 of the lower section is maintained by the lifting ropes 200, and the newly added section of outer sleeve 310 and the outer sleeve 310 of the lower section are connected by at least one set of connecting mechanisms 314.

[0072] Step S3, please refer to Figures 9 to 11 The remaining two suspension ropes 200 on the suspension rings 314-1 of the lower outer sleeve 310 below the newly added outer sleeve 310 are removed and replaced with the two suspension rings 314-1 of the newly added outer sleeve 310 that are not connected to the suspension ropes 200, and the entire Hough outer sleeve is hoisted. At this point, the newly added outer sleeve 310 and the lower outer sleeve 310 are flexibly connected. Optionally, the suspension rings 314-1 of the other set of connecting mechanisms 314 of the newly added outer sleeve 310 and the lower outer sleeve 310 are fastened to the fastening pins 314-2, and the newly added outer sleeve 310 and the lower outer sleeve 310 are rigidly connected. The entire Hough outer sleeve is finally suspended and connected to the uppermost outer sleeve 310 via the four suspension ropes 200.

[0073] When the water depth continues to increase, the inner casing 320 is continuously pulled up and a new outer casing 310 is added in the above manner to increase the height of the entire half-type riprap pipe 300. The riprap is continuously fed through the riprap pipe 300 and dropped onto the seabed to form an underwater foundation.

[0074] Step S4, please refer to Figures 11 to 5 When the seabed topography changes and the water depth decreases significantly, the outer casing 310 of the uppermost section is removed in the opposite manner as described above, and the inner casing 320 is lowered. The riprap is continuously fed through the riprap guide tube 300 and dropped onto the seabed to form an underwater foundation.

[0075] When the water depth continues to decrease, the uppermost outer casing 310 is removed and the inner casing 320 is lowered in the above manner to reduce the height of the entire half-type riprap pipe 300. The riprap is continuously fed through the riprap pipe 300 and dropped onto the seabed to form an underwater foundation.

[0076] Please refer to Figure 4In the Hough-type uninterrupted feeding and riprap method provided in an embodiment of the present invention, a set of connecting mechanisms 314 are used between each section of the outer casing 310 to form a flexible connection of the outer casing 310, so that adjacent outer casings 310 not wrapped with the inner casing 320 can swing and bend to adapt to the unevenness of the seabed and the changes in water flow impact, thereby ensuring the accurate and uniform delivery of riprap.

[0077] The Hough riprap conduit 300, the uninterrupted riprap feeding device 1, and the method provided in the embodiments of the present invention, when constructing an underwater foundation by riprap, when changes in the seabed topography cause changes in the water depth, by adjusting the depth of the inner casing 320 inserted into the outer casing 310, and increasing or decreasing the number of sections of the outer casing 310, thereby maintaining a constant height between the Hough riprap conduit 300 and the seabed, thereby continuously supplying riprap materials to the seabed through the Hough riprap conduit 300 to form an underwater foundation.

[0078] The Half-type riprap pipe 300, uninterrupted feeding riprap device 1, and method provided by the embodiments of the present invention enable the Half-type riprap pipe 300 to maintain a constant height difference from the seabed by increasing or decreasing the number of sections of the outer casing 310 while continuously feeding material. This allows the riprap pipe 300 to operate continuously without affecting the efficiency, progress, or construction period of the riprap operation. This ensures the uniformity of the riprap layer thickness of the underwater foundation, avoids or reduces construction joints, and thus ensures the construction quality and structural strength of the underwater foundation. These advantages include high underwater foundation construction efficiency, a short construction period, and high construction quality.

[0079] The Hough-type riprap pipe 300, the uninterrupted feeding riprap device 1, and the method provided in the embodiments of the present invention enable the Hough-type riprap pipe 300 to be used continuously by frequently adjusting the length of the Hough-type riprap pipe 300 during uninterrupted feeding in a deepwater environment, thereby avoiding the safety risk of sedimentation and blockage in the traditional riprap pipe 300 during intermittent feeding and eliminating the safety hazard of pipe blockage.

8. A Hough type uninterrupted feeding stone throwing method, characterized in that: The Hough type uninterrupted feeding riprap device according to claim 7 comprises: Normal construction mode: The outer sleeve of the riprap pipe is hoisted to the underwater seabed by a lifting rope, and the lower end of the outer sleeve of the riprap pipe is kept at a constant height from the seabed. The riprap material is supplied to the riprap pipe by a conveyor belt, so that the riprap material is dropped to the seabed through the riprap pipe to form an underwater foundation; Water depth change fine-tuning mode: When the seabed topography changes and causes a slight increase in water depth, the outer casing is lowered by adjusting the lifting rope to maintain a constant height above the seabed, the inner casing is pulled up and kept inside the outer casing, and riprap is continuously supplied to the riprap pipe through the conveyor belt, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation; When the seabed topography changes and causes a slight decrease in water depth, the outer casing is raised by adjusting the lifting rope to maintain a constant height above the seabed, and the inner casing is lowered and kept inside the outer casing. The conveyor belt is used to continuously supply riprap to the riprap pipe, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation. Water depth change coarse adjustment mode: When the seabed topography changes and causes the water depth to increase significantly, the outer casing is lowered by adjusting the lifting rope, and the inner casing is pulled up to keep it inside the outer casing. The conveyor belt is used to continuously supply riprap to the riprap pipe, and its height with the seabed is kept constant, so that the riprap is dropped through the riprap pipe to the seabed to form an underwater foundation. The two lifting ropes connected to the relatively distributed lifting rings of the uppermost outer sleeve are respectively connected to the lifting rings of a new front half pipe and a new rear half pipe. The newly added front and rear half pipes are hoisted on both sides of the removed inner sleeve and connected through a locking mechanism to form an outer sleeve of a newly added section. The outer sleeve of the newly added section wraps around the removed inner sleeve and the lifting ropes are used to maintain the hoisting of the outer sleeve of the newly added section and the outer sleeve of the lower section. The outer sleeve of the newly added section and the outer sleeve of the lower section are connected through at least one set of connecting mechanisms. Remove the remaining two lifting ropes from the lifting rings of the lower outer casing below the newly added outer casing and replace them with the two lifting ropes that are not connected to the lifting rings of the newly added outer casing to lift the entire Hough outer casing; 9. The Hough type uninterrupted feeding riprap method according to claim 8, characterized in that: Also includes: When the seabed topography changes and the water depth decreases significantly, the outer casing of the uppermost section is removed in the reverse manner of the above, and the inner casing is lowered. The riprap is continuously fed through the riprap pipe and dropped onto the seabed to form an underwater foundation.

10. The Hough type uninterrupted feeding riprap method according to claim 9, characterized in that: A set of connecting mechanisms is used between each section of the outer casing to form a flexible outer casing, so that the adjacent outer casings not wrapped in the inner casing can swing and bend to adapt to the unevenness of the seabed and changes in water flow impact, ensuring the accurate and uniform placement of the riprap.
