Description

Technical Field

[0001] The present invention relates to the field of underwater foundation construction in deep - water engineering, and particularly relates to a stone - throwing conduit system, and a clamp - type suspension adjustment device, system and method for continuous stone - throwing operation. Background Art

[0002] For the underwater foundation of deep - water engineering such as the ocean and lakes, the stone - throwing method is adopted to construct by putting stone - throwing materials through a stone - throwing conduit system that sinks from the sea surface to the seabed. However, in deep - water engineering, the water depth changes due to the influence of seabed topography changes or tidal level fluctuations, and it is not a constant depth. This affects the height difference between the stone - throwing conduit system and the seabed. Therefore, it is necessary to adjust the length of the stone - throwing conduit system to ensure a constant height difference between the stone - throwing conduit system and the seabed surface, and to ensure the conveying quality of the stone - throwing materials. Among them, the stone - throwing conduit system is generally composed of standard sections with flange plates spliced together by flange bolts. When adjusting the length of the stone - throwing conduit system, it is necessary to interrupt the supply of stone - throwing materials and thus interrupt the stone - throwing operation. Then, after adjusting the length of the stone - throwing conduit system, the supply of stone - throwing materials is restored, and the stone - throwing operation is resumed by putting the stone - throwing materials through the stone - throwing conduit system after length adjustment. This affects the construction progress, construction quality, construction period of the underwater foundation and the safety risk in the deep - water environment during the length adjustment of the stone - throwing conduit system. Summary of the Invention

[0010] Furthermore, for the clamp-type suspension adjustment system for continuous stone throwing operation of the stone throwing catheter system provided by the present invention, the Haff ring-embedded stone throwing catheter system includes an outer catheter and an inner catheter inserted and connected therein. The outer catheter is composed of multiple sections spliced together. Flange plates are provided at the upper and lower ends of each section of the outer catheter.

The inner catheter support frame clamps and suspends to carry the inner catheter, and each group of clamp catheter suspension components in the closed state in the clamp catheter suspension system jointly clamp and suspend to carry the outer catheter; The stone-throwing materials are conveyed into the Haff-ring-embedded stone-throwing catheter system through a conveyor belt, and the stone-throwing materials are put onto the seabed surface through the Haff-ring-embedded stone-throwing catheter system; Through the alternate loading of the outer catheter by each group of clamp catheter suspension components in the clamp catheter suspension system and the telescopic control of the automatic telescopic rod, the length adjustment of the extension or shortening of the outer catheter is realized.

[0012] Furthermore, the method for adjusting the clamp suspension of the continuous stone-throwing operation of the stone-throwing catheter system provided by the present invention further includes: Through the alternate loading of the outer catheter by each group of clamp catheter suspension components and the outer catheter clamping stability system in the clamp catheter suspension system and the telescopic control of the automatic telescopic rod, the length adjustment of the outer catheter relative to the inner catheter is realized.

[0018] The present invention will be described in detail below with reference to the accompanying drawings: According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present invention.

[0019] Embodiment 1 Please refer to Figures 10 to 15 , Embodiment 1 of the present invention provides a Huff-ring embedded stone-throwing conduit system 200, including an outer conduit 220 and an inner conduit 210 inserted and connected therein.

[0020] Please refer specifically to Figure 11 , the length of the inner conduit 210 is less than that of the outer conduit 220. The inner conduit 210 includes a pipe body and a frustum-shaped packing port at its upper end, that is, the packing port can be trumpet-shaped. The inner conduit 210 is always wrapped by the outer conduit 220 to ensure that when one section of the outer conduit 220 is installed or removed, the entire Huff-ring embedded stone-throwing conduit system 200 can still be in a working state.

[0021] Please refer specifically to Figure 12 , the entire outer conduit 220 is composed of multiple sections of outer conduits 220 with flanges 222 spliced together. Each section of the outer conduit 220 is composed of two Huff-type segments 221 spliced together. The upper and lower ends of each Huff-type segment 221 are half flanges 222. A plurality of Huff ear plates 223 are provided on each Huff-type segment 221. The two Huff-type segments 221 are spliced into a complete section of the outer conduit 220 by passing a screw 224 through their respective Huff ear plates 223 and locking with a nut 225.

[0022] Please refer specifically to Figures 12 to 13, after the upper and lower flange plates 222 of two adjacent outer conduits 220 are butted, that is, the flange plates 222 of the upper and lower adjacent outer conduits 220 are not connected. The adjacent two outer conduits 220 are wrapped around the flange plates 222 by a split type ring groove hoop 230 for flexible connection. Then, the flange plates 222 of the upper and lower outer conduits 220 are restricted to have a certain degree of freedom of movement space within the split type ring groove hoop 230, so that the upper and lower outer conduits 220 can axially swing in any direction, causing the adjacent two outer conduits 220 to bend. The axial swing relationship between the upper and lower outer conduits 220 can be controlled by an external traction force. That is to say, the distance of the ring groove of the split type ring groove hoop 230 in the height direction is greater than the sum of the thicknesses of the upper and lower flange plates 222, so that the upper and lower outer conduits 220 have a certain degree of freedom of movement space within the split type ring groove hoop 230.

[0023] Please refer to with emphasis Figures 14 to 15 , where the split type ring groove hoop 230 is composed of two semi-circular half ring groove hoops 231. Both ends of each half ring groove hoop 231 have split lugs 223. The two half ring groove hoops 231 are connected into a complete split type ring groove hoop 230 by a screw 224 passing through the corresponding split lugs 223. The two ends of the split type ring groove hoop 230 are not limited to the through connection of the screw 224 and the nut 225, and one end can be in a hinged relationship.

[0024] Embodiment 1 of the present invention provides a split ring embedded type riprap conduit system 200. Each outer conduit 220 below the inner conduit 210 can axially swing and bend at the flexible connection to adapt to the height change of the seabed terrain. Thus, the split ring embedded type riprap conduit system 200 with axial swing accurately discharges riprap materials to the seabed surface with height changes, ensuring the thickness uniformity of the riprap materials discharged on the seabed surface and improving the construction quality of the underwater foundation of deep-water projects.

[0025] Embodiment 2 Please refer to Figures 1 to 9 、 Figure 16 , Embodiment 2 of the present invention provides a clamp type suspension adjustment device 100 for continuous riprap operation of a riprap conduit system, including a conduit support frame 110, an inner conduit support frame 120, a clamp type conduit suspension system 130, and an optional outer conduit clamping and stabilizing system 140, where: Please refer to with emphasis Figures 2 to 3 , the conduit support frame 110 includes at least two parallel and spaced vertical tracks 111. Each track 111 can be fixedly supported by a frame 112 on an operation ship 400 located in a deep-water environment. To ensure the stability of the two tracks 111 installed on the operation ship 400, a cross bar can be connected to the lower ends of the two tracks 111.

[0026] Please refer to with emphasisFigure 2 and Figure 16 , the inner conduit support frame 120 is horizontally arranged between the upper ends of the two tracks 111. Specifically, it may include a T-shaped connector 121 connected between the two tracks 111 and a ring frame 122 connected thereto. On the one hand, the T-shaped connector 121 is used to ensure the length of the ring frame 122 extending out of one side of the plane where the two tracks 111 are located, and on the other hand, it is used to ensure the structural stability of the two tracks 111, so as to ensure the structural stability of the conduit support frame 110 arranged on the workboat 400. The ring frame 122 is used to support the inner conduit 210. Specifically, after the inner conduit 210 is inserted into the ring frame 122, it is then inserted into the outer conduit 220, thereby limiting the inner conduit 210 in the horizontal direction.

[0027] Please refer to Figures 1 to 3 , the clamp-type conduit suspension system 130 includes at least two groups of clamp-type conduit suspension components 131 and an automatic telescopic rod 132 connected between any two adjacent groups of clamp-type conduit suspension components 131. The upper group of clamp-type conduit suspension components 131 is attached to the two tracks 111 of the conduit support frame 110, and the remaining groups of clamp-type conduit suspension components 131 are slidably arranged on the two tracks 111 of the conduit support frame 110. Figure 1 Three groups of clamp-type conduit suspension components 131 are exemplified in Figure 2 Two groups of clamp-type conduit suspension components 131 are exemplified in. The automatic telescopic rod 132 can be a hydraulic cylinder, an electric screw rod, etc. In order to adjust the adjustable position installation of the upper group of clamp-type conduit suspension components 131 on the track 111 to be applicable to the heights of different workboats 400, the upper group of clamp-type conduit suspension components 131 can first be slidably arranged on the track 111 to adjust the position, and then locked and attached to the track 111 by a locking bolt or a pin. Of course, the upper group of clamp-type conduit suspension components 131 can also be directly fixedly arranged and attached to the track 111 without adjusting the position.

[0028] Please refer to Figures 5 to 7, each set of clamp - type conduit suspension assemblies 131 includes a lateral movement guide rail 131a, a chute 131b, a mounting seat 131c, a lateral movement oil cylinder 131d, a cantilever 131e, and a limit seat 131f. The lateral movement guide rail 131a is slidably connected to the two track rails 111 respectively through two chutes 131b thereon perpendicular to the plane where the two track rails 111 are located. There are four mounting seats 131c, which can be ear - plate structures. Every two mounting seats 131c form a group and are arranged on the lateral movement guide rail 131a at a predetermined interval. The two groups of mounting seats 131c are distributed in the middle area of the upper and lower surfaces of the lateral movement guide rail 131a. There are two lateral movement oil cylinders 131d. One lateral movement oil cylinder 131d is arranged between a group of mounting seats 131c on the upper surface of the lateral movement guide rail 131a, and the other lateral movement oil cylinder 131d is arranged between a group of mounting seats 131c on the lower surface of the lateral movement guide rail 131a. The lateral movement oil cylinders 131d are respectively arranged on the corresponding groups of mounting seats 131c through their cylinder barrels. The push rods of the lateral movement oil cylinders 131d extend from the end where one mounting seat 131c is located, and the extending directions of the push rods of the two lateral movement oil cylinders 131d are opposite. The cantilever 131e is L - shaped and is slidably arranged on the lateral movement guide rail 131a. The push rod of each lateral movement oil cylinder 131d is connected to a limit seat 131f arranged on one of the L - shaped cantilevers 131e. By controlling the two lateral movement oil cylinders 131d to extend or retract in opposite directions, and then driving the two L - shaped cantilevers 131e to be in a closed state or an open state through the limit seat 131f connected to the push rod. Figure 5 Illustrates the clamp - type conduit suspension assembly 131 in the closed state, that is, the two L - shaped cantilevers 131e are in the closed state. Figure 6 Illustrates the clamp - type conduit suspension assembly 131 in the open state, that is, the two L - shaped cantilevers 131e are in the open state. In order to improve the structural stability of the clamp - type conduit suspension assembly 131 when it is in the closed state, the transverse arm rods of the two L - shaped cantilevers 131e are staggered and distributed parallel to the lateral movement guide rail 131a. There are mounting holes or mounting positions for installing the automatic telescopic rod 132 on the lateral movement guide rail 131a.

[0029] Please refer to Figure 4 and Figure 16, on the vertical arm of the cantilever 131e of the upper group of clamp-type conduit suspension assemblies 131 perpendicular to the side-shift guide rail 131a, there is a split ring installation tooling 133 composed of two semi-circular arc clamps each less than a half circle. When the upper group of clamp-type conduit suspension assemblies 131 is in the closed state, it is used to control the split ring installation tooling 133 to clamp the split ring groove clamp 230 suspended at the connection of the top two outer conduits 220, thereby bearing the weight of the entire outer conduit 220 and preventing it from falling into the water. When the remaining groups of clamp-type conduit suspension assemblies 131 are in the closed state, they support the split ring groove clamp 230 at the connection of two outer conduits 220 at the corresponding position through two L-shaped cantilevers 131e, that is, clamp and suspend the outer conduit 220 to bear the load. Through the alternating bearing of the entire outer conduit 220 by each group of clamp-type conduit suspension assemblies 131 and the telescopic control of the cooperation with the automatic telescopic rod 132, the lifting control of the entire outer conduit 220 can be realized, which is applicable to the situation of increasing or decreasing the outer conduit 220 in whole sections.

[0030] Please refer to Figure 2 , Figures 8 to 9 and Figure 16 , the outer conduit clamping stability system 140, at least one, is slidably arranged on the two tracks 111 of the jacket 110. Figure 2Two external catheter clamping and stabilizing systems 140 are illustrated. An automatic telescopic rod 132 is also connected between the external catheter clamping and stabilizing system 140 and its adjacent clamp-type catheter suspension assembly 131 or between adjacent external catheter clamping and stabilizing systems 140. The external catheter clamping and stabilizing system 140 includes a hollow stabilizing frame 141, which can be U-shaped, or a semicircular shape larger than 1 / 2 circle, or a ring shape such as a square ring or a circular ring. The stabilizing frame 141 is slidably connected to the two rails 111 through two slide grooves 131b provided thereon. A clamp 142 is provided on the stabilizing frame 141 for clamping the tube body of the external catheter 220, that is, not clamping the half ring mounting fixture 133 of the external catheter 220, that is, the external catheter clamping and stabilizing system 140 can clamp and suspend the external catheter 220. The corresponding stabilizing frame 141 is provided with a mounting hole or mounting position for connecting the automatic telescopic rod 132. The clamp 142 includes two cylinder seats 142a symmetrically disposed on either side of a stabilizing frame 141 in the hollow region, a telescopic cylinder 142b disposed on each cylinder seat 142a, and a clamping plate 142c connected to each telescopic cylinder 142b, wherein the clamping plate 142c is an arc-shaped plate approximately half a circle. The clamp 142 can be controlled to be in a closed state to clamp the outer conduit 220, and can be controlled to be in an open state to release the outer conduit 220 and release its connection constraints. When the clamp 142 is in a closed state, the outer conduit clamping and stabilizing system 140 is in a closed state, and when the clamp 142 is in an open state, the outer conduit clamping and stabilizing system 140 is in an open state. The outer conduit clamping and stabilizing system 140 and the clamp-type conduit suspension system 130 work together to alternately support the outer conduit 220. In conjunction with the telescopic control of the automatic telescopic rod 132, the outer conduit 220 can be raised and lowered, telescoped, and lengthened or shortened by increasing or decreasing the number of sections of the outer conduit 220. The closed and open states of the clamp 142 are controlled by a telescopic cylinder 142b driving two clamping plates 142c.

[0031] The clamp-type suspension adjustment device 100 for continuous riprap operation of a riprap catheter system provided in the second embodiment of the present invention, when in use, carries the inner catheter 210 through the inner catheter support frame 120, and alternately carries, clamps and suspends the outer catheter 220 through each group of clamp-type catheter suspension components 131 of the clamp-type catheter suspension system 130. When connected to the outer catheter clamping and stabilizing system 140, the outer catheter clamping and stabilizing system 140 can be used to clamp and suspend the outer catheter 220. In conjunction with the telescopic control of the automatic telescopic rod 132, the outer catheter 220 can be lengthened or shortened relative to the inner catheter 210 under the condition of continuous supply of riprap materials, and the length of the entire outer catheter 220 can be adjusted and controlled by adding or removing one or more sections of the outer catheter 220, so as to adapt to changes in water depth and ensure that the half ring embedded riprap catheter system 200 is at a constant height difference with the seabed surface.

[0035] Step S503, please refer to Figures 17 to 23 , realizing the lengthening or shortening adjustment of the outer catheter 220 by alternately bearing the outer catheter 220 by each group of clamping catheter suspension components 131 in the clamping catheter suspension system 130 and the possibly connected outer catheter clamping and stabilizing system 140 and coordinating the telescopic control of the automatic telescopic rod 132.

[0036] In step S503, when the water depth increases, the steps for lengthening adjustment of the outer catheter 220 include: Step S503-1, please refer to Figures 17 to 18 , control the upper set of clamp-type conduit suspension assemblies 131 to be in the open state and drive the split-ring installation tooling 133 thereon to be in the open state, release the clamping suspension load-bearing of the outer conduit 220 by the upper set of clamp-type conduit suspension assemblies 131, so as to release the connection of the split-ring groove hoop 230 at the connection between it and the uppermost two sections of the outer conduit 220, that is, release the constraint on the outer conduit 220 at the corresponding position of the upper set of clamp-type conduit suspension assemblies 131, and keep the remaining sets of clamp-type conduit suspension assemblies 131 in the closed state to carry out the clamping suspension load-bearing of the outer conduit 220. At this time, the outer conduit 220 bears its load through the remaining sets of clamp-type conduit suspension assemblies 131. When connecting the outer conduit clamping and stabilizing system 140, the outer conduit clamping and stabilizing system 140 can also be used to jointly carry out the clamping suspension load-bearing of the outer conduit 220. Through the elongation of the automatic telescopic rod 132 between the upper and lower sets of clamp-type conduit suspension assemblies 131, drive the remaining clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected to lower the outer conduit 220 as a whole by one section ( Figure 18 The downward arrow in

[0037] Step S503-2, please refer to Figures 19 to 20 , on the workboat 400, butt-joint two new split-type pipe segments 221 around the exposed area of the inner conduit 210 to wrap the inner conduit 210, and pass through and lock the screw 224 and the nut 225 on the split ears 223 of the two split-type pipe segments 221 to splice them into a new section of the outer conduit 220. Butt-joint the new section of the outer conduit 220 on the sunken outer conduit 220. At this time, the new section of the outer conduit 220 is the uppermost section of the outer conduit 220. Install a split-ring groove hoop 230 at the butt joint of the flanges 222 of the uppermost two sections of the outer conduit 220 to flexibly connect the uppermost two sections of the outer conduit 220.

[0038] Step S503-3, please refer to Figures 21 to 23 , restore the upper set of clamp-type conduit suspension assemblies 131 to the closed state to clamp and suspend and carry the lengthened and adjusted outer conduit 220 on the split-ring groove hoop 230 of the uppermost two sections of the outer conduit 220, control the remaining sets of clamp-type conduit suspension assemblies 131 and control the outer conduit clamping and stabilizing system 140 that may be connected to be in the open state. At this time, the entire outer conduit 220 is held in the clamping suspension load-bearing of its load through the upper set of clamp-type conduit suspension assemblies 131. By controlling the retraction of the automatic telescopic rod 132 between the upper and lower adjacent sets of clamp-type conduit suspension assemblies 131, the remaining sets of clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected slide relative to the track 111 to restore to the initial installation position with the outer conduit 220 (Figure 22 The upward arrow in Figure 22 indicates that the remaining groups of clamp-type catheter suspension assemblies 131 and the possibly connected outer catheter clamping and stabilizing system 140 move upward to restore the initial installation position), and control the remaining groups of clamp-type catheter suspension assemblies 131 and control the possibly connected outer catheter clamping and stabilizing system 140 to be in a closed state, restoring the clamping and suspension load-bearing of the outer catheter 220. At this time, the outer catheter 220 is jointly clamped, suspended, and load-bearing by the clamp-type catheter suspension assemblies 131 of each group of the clamp-type catheter suspension system 130 and the possibly connected outer catheter clamping and stabilizing system 140. Thus, the length extension adjustment of one section of the outer catheter 220 is achieved. Repeating the above steps can achieve the length extension adjustment of the next section of the outer catheter 220 under continuous feeding conditions.

[0039] The single-section length extension adjustment of the outer catheter 220 while maintaining continuous feeding can be summarized as follows: Initial state: The clamp-type catheter suspension assemblies 131 of each group of the clamp-type catheter suspension system jointly clamp and suspend the outer catheter 220 and bear its load. When there is an outer catheter clamping and stabilizing system 140, the outer catheter 220 is assisted in clamping, suspending, and load-bearing through the outer catheter clamping and stabilizing system 140.

[0040] Load transfer: Control the upper group of clamp-type catheter suspension assemblies 131 to be in an open state, releasing its restraint connection with the outer catheter 220; the load of the outer catheter 220 is transferred to the remaining groups of clamp-type catheter suspension assemblies 131. When there is an outer catheter clamping and stabilizing system 140, the load of the outer catheter 220 is assisted in clamping, suspending, and load-bearing through the outer catheter clamping and stabilizing system 140.

[0041] Outer catheter downward movement: The automatic telescopic rod 132 between the upper and lower groups of clamp-type catheter suspension assemblies 131 extends, driving the entire outer catheter 220 downward; the inner catheter 210 is exposed to form an outer catheter installation window.

[0042] Installation of the new section of the outer catheter: Install the split tube segment 221 at the outer catheter installation window where the inner catheter 210 is exposed to form a new section of the outer catheter on the sunken outer catheter 220, and install the split ring groove hoop 230 between the flange plates 222 between the new section of the outer catheter 220 and the sunken outer catheter 220.

[0043] Clamping by the upper group of clamp-type catheter suspension assemblies: The upper group of clamp-type catheter suspension assemblies 131 is in a closed state, driving the hafnium ring installation tooling 133 thereon to be in a closed state to clamp, suspend, and load-bearing the outer catheter 220.

[0044] Load reset: Control the clamp-type catheter suspension system 130 and the possibly connected outer catheter clamping and stabilizing system 140 to rise through the automatic telescopic rod 132 to restore the initial installation position on the track 111 and jointly clamp, suspend, and load-bearing the load of the lengthened outer catheter 220.

[0045] In step S503, when the water depth decreases, the steps of shortening and adjusting the outer conduit 220 include: Step S503-4, when the water depth decreases, control the upper set of clamp-type conduit suspension assemblies 131 and the Haff ring installation tooling 133 thereon to be in an open state, release the connection of the upper set of clamp-type conduit suspension assemblies 131 to the outer conduit 220, that is, release the screws 224 and nuts 225 connected to the Haff-type segments 221 of the uppermost section of the outer conduit 220, remove the two Haff-type segments 221 of the uppermost section of the outer conduit 220 to expose the inner conduit 210, and keep the remaining set of clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected to clamp, suspend, and carry the outer conduit 220 stably.

[0046] Step S503-5, control the upper set of clamp-type conduit suspension assemblies 131 of the clamp-type conduit suspension system 130 to be in a closed state to clamp, suspend, and carry the load of the outer conduit 220, control the remaining clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 1,40 that may be connected to be in an open state, release the connection with the outer conduit 220, control the automatic telescopic rod 132 to extend, and connect the remaining clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected to the next section position of the entire outer conduit 220 to form a new constraint.

[0047] Step S503-6, control the upper set of clamp-type conduit suspension assemblies 131 of the clamp-type conduit suspension system 130 to be in an open state to release its connection constraint with the outer conduit 220, keep the remaining clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected to be in a closed state to clamp, suspend, and carry the load of the outer conduit 220, control the automatic telescopic rod 132 to retract to drive the remaining clamp-type conduit suspension assemblies 131 and the outer conduit clamping and stabilizing system 140 that may be connected to rise one section position relative to the outer conduit 220, and control the upper set of clamp-type conduit suspension assemblies 131 to be in a closed state to restore the connection to the outer conduit 220, realizing the shortening and adjusting of the outer conduit 220 under continuous feeding.

[0048] During the process of significantly lengthening or shortening the outer conduit 220, through the increase or decrease in the number of sections of the outer conduit 220, each section of the outer conduit 220 is spliced through the Haff-type segments 221 to realize the modular expansion and maintenance of the outer conduit 220.

[0049] Please refer to Figure 24 , in order to realize the small-scale adjustment of the outer conduit 220, Embodiment 4 of the present invention provides a method for adjusting the clamp suspension of a continuous stone throwing operation of a stone throwing conduit system, which may further include: The upper set of clamp-type conduit suspension assemblies 131 of the control clamp-type conduit suspension system 130 is in an open state to solve the constraint of connecting the upper set of clamp-type conduit suspension assemblies 131 to the outer conduit 220. The remaining clamp-type conduit suspension assemblies 131 and the possibly connected outer conduit clamping and stabilizing system 140 are all in a closed state. Through the telescopic control of the automatic telescopic rod 132, the remaining clamp-type conduit suspension assemblies 131 and the possibly connected outer conduit clamping and stabilizing system 140 slide up and down relative to the track 111 to control a small adjustment of the outer conduit 220 ( Figure 24 The downward arrow in indicates that the outer conduit 220 moves downward for a small downward adjustment). After the length of the outer conduit 220 is adjusted, the upper set of clamp-type conduit suspension assemblies 131 of the control clamp-type conduit suspension system 130 is in a closed state to resume its clamping, hanging, and load-bearing of the outer conduit 220.

[0050] Among them, a large adjustment of the outer conduit 220 means that the adjustment range of the outer conduit 220 is greater than the length of the inner conduit 210. A small adjustment of the outer conduit 220 means that the adjustment range of the outer conduit 220 is less than the length of the inner conduit 210.

[0051] The clamp suspension adjustment method for the continuous stone throwing operation of the stone throwing conduit system provided in the fourth embodiment of the present invention can realize the adjustment of lengthening or shortening the length of the outer conduit 220 during the continuous stone throwing operation, that is, adjusting the length of the Haff ring-embedded stone throwing conduit system 200, without interrupting the stone throwing operation, adapting to the continuous stone throwing operation with water depth changes, improving the construction efficiency of the underwater foundation, shortening the construction period, and avoiding the safety risk of pipe blockage when the stone throwing operation is interrupted. When making a large adjustment of lengthening or shortening the outer conduit 220, the outer conduit clamping and stabilizing system 140 can be not connected. When making a small adjustment of the length of the outer conduit 220, the outer conduit clamping and stabilizing system 140 needs to be connected. To increase the length adjustment range of the Haff ring-embedded stone throwing conduit system 200, the clamp-type conduit suspension system 130 and the outer conduit clamping and stabilizing system 140 are connected at the same time.

[0052] The clamp suspension adjustment method for the continuous stone throwing operation of the stone throwing conduit system provided in the fourth embodiment of the present invention applies a traction force to the outer conduit 220 in the underwater project, so that the flanges 222 passed by two adjacent outer conduits 220 axially swing and bend in any direction within the Haff-type ring groove hoop 230. At this time, the outer conduit 220 is in a bent state, not the initial vertical state, to adapt to the problem of uneven seabed caused by the height change of the seabed topography and the change of water flow impact, avoid or reduce the construction joints of the thrown stones, ensure the accurate placement and uniform placement of the thrown stones, and ensure the construction quality of the underwater foundation.

[0053] The stone-throwing conduit system provided by the embodiment of the present invention, its continuous stone-throwing operation clamp-type suspension adjustment device, system and method can adjust the length of the outer conduit 220 during continuous stone-throwing operation to adapt to the change of increasing or decreasing water depth, ensure a constant height difference between the outer conduit 220 and the seabed surface, without interrupting the supply of stone materials, and without affecting the construction progress, construction quality and construction period of the underwater foundation.

Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.
