Technical Field

[0001] This application relates to the field of underwater concrete pouring technology, and in particular to an underwater pouring device and a method for pouring underwater cementitious materials. Background Technology

[0002] Marine structures (such as pile foundations and cylindrical foundations) installed on the seabed alter the surrounding flow field, causing erosion of the surface soil and creating localized scour pits. Scour pits are a significant factor affecting the long-term stability and operational safety of marine structures. Rockfill protection is currently the most common and economical scour prevention measure for marine structures.

The other end of the grouting pipe passes through the inner telescopic tube, the outer telescopic tube and the limiting conduit in sequence.

[0014] In the preferred embodiment of the above-mentioned underwater casting device, a buoyancy component is provided inside the grouting pipe. The buoyancy component is configured to move with the grouting material under the gravity of the grouting material inside the grouting pipe, so as to reduce the flow velocity of the grouting material.

[0015] In the preferred technical solution of the above-mentioned underwater casting device, a protective agent pumping system is also included. The protective agent pumping system includes a storage tank, a pump and a pumping pipe. The storage tank is used to store the protective agent. The pump is installed in the storage tank.

[0017] In the preferred embodiment of the above-mentioned underwater casting device, the horizontal distance adjustment component includes a telescopic drive component, which is disposed on the base.

Finally, the cementitious material is injected into the casting point through the grouting pipe, ensuring the outlet is at the preset position. This improves the accuracy of the cementitious material's casting point. By using the telescopic pipe positioning system and changing the telescopic pipe's extension length, the casting point of the cementitious material can be controlled in real time, solving the technical problems of uncontrollable and inaccurate casting points in existing cementitious material casting methods.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0040] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0041] After the rock-laying protection construction process, the effect of rock-laying protection can be improved by pouring cementing material. In the existing technology, the cementing material is transported to the pouring point through pipelines.

[0042] Currently, the placement of cementitious materials in pipelines is uncontrollable and inaccurate.

[0043] To address the technical problems of uncontrollable and inaccurate pouring points of existing cementitious materials, this application proposes an underwater pouring device and a method for pouring underwater cementitious materials. The underwater pouring device includes a construction vessel, a telescopic pipe, a telescopic pipe positioning system, and a grouting system. The telescopic pipe positioning system includes a horizontal angle adjustment component and a horizontal distance adjustment component. The horizontal angle adjustment component drives the telescopic pipe to rotate around the construction vessel. The horizontal distance adjustment component drives the telescopic pipe to move relative to the construction vessel, thereby changing the horizontal distance between the outlet of the telescopic pipe and the construction vessel. The grouting system includes a grouting pipe and a limiting guide pipe. The limiting guide pipe is connected to the outlet of the telescopic pipe. One end of the grouting pipe is located at the end of the telescopic pipe furthest from the limiting guide pipe, and the other end of the grouting pipe passes sequentially through the telescopic pipe and the limiting guide pipe.

[0044] This underwater casting device uses a mobile construction vessel to initially position the telescopic pipe. Then, a telescopic pipe positioning system adjusts the angle and horizontal distance of the pipe to align the outlet of the bonding material with the casting point. The telescopic pipe's extension length is then controlled to ensure the distance between the outlet and the casting point remains within a preset range. Finally, the bonding material is injected into the casting point through a grouting pipe, ensuring the outlet is at the preset position. This improves the accuracy of the bonding material's casting point. By using the telescopic pipe positioning system and adjusting the extension length, the casting point can be controlled in real time, solving the technical problems of uncontrollable and inaccurate casting points in existing bonding materials systems.

[0045] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0048] In the embodiments of this application, reference is made to Figures 1 to 3 As shown, the first aspect of the embodiments of this application provides an underwater casting device, including a construction vessel 100, a telescopic pipe 200, a telescopic pipe positioning system 300, and a grouting system;

[0049] The telescopic tube positioning system 300 includes a horizontal angle adjustment component 310 and a horizontal distance adjustment component 320;

[0050] The horizontal angle adjustment component 310 is installed on the construction vessel 100. The output end of the horizontal angle adjustment component 310 is connected to the telescopic tube 200. The horizontal angle adjustment component 310 is configured to drive the telescopic tube 200 to rotate around the construction vessel 100.

[0051] A horizontal distance adjustment component 320 is installed on the construction vessel 100. The output end of the horizontal distance adjustment component 320 is connected to the telescopic pipe 200. The horizontal distance adjustment component 320 is configured to drive the telescopic pipe 200 to move relative to the construction vessel 100, so as to change the horizontal distance between the outlet of the telescopic pipe 200 and the construction vessel 100.

[0052] The grouting system includes a grouting pipe 400 and a limiting conduit 600. The limiting conduit 600 is connected to the outlet of the telescopic pipe 200. One end of the grouting pipe 400 is located at the end of the telescopic pipe 200 away from the limiting conduit 600, and the other end of the grouting pipe 400 passes through the telescopic pipe 200 and the limiting conduit 600 in sequence.

[0053] The telescopic pipe positioning system 300 of the underwater casting device of this application is used to position the telescopic pipe 200 so that the outlet of the grouting pipe 400 or the outlet of the limiting conduit 600 is located directly above the casting point, thereby ensuring that the outlet of the cementing material is located directly above the casting point.

[0054] It should be noted that the outlet of the cementing material can be either the outlet of the grouting pipe 400 or the outlet of the limiting conduit 600. When the extension length of the telescopic pipe 200 is changed so that the outlet of the grouting pipe 400 extends out of the limiting conduit 600, the outlet of the cementing material is the outlet of the grouting pipe 400. When the extension length of the telescopic pipe 200 is changed so that the outlet of the grouting pipe 400 is located inside the limiting conduit 600, the outlet of the cementing material is the outlet of the limiting conduit 600. In this embodiment, when the height between the outlet of the grouting pipe 400 and the pouring point is within 2m, the outlet of the grouting pipe 400 is the outlet of the cementing material. When the height between the outlet of the grouting pipe 400 and the pouring point exceeds 2m, the telescopic length of the telescopic pipe 200 is changed so that the outlet of the grouting pipe 400 is located inside the limiting conduit 600. At this time, the outlet of the limiting conduit 600 is the outlet of the cementing material. Thus, the limiting conduit 600 achieves the dual functions of supporting the grouting pipe 400, ensuring that the grouting pipe 400 does not undergo significant bending deformation during construction, and indirectly adjusting the length of the grouting pipe to cope with the complex marine environment and ensure the quality of cementing material pouring.

[0055] The telescopic pipe positioning system 300 includes a horizontal angle adjustment component 310 and a horizontal distance adjustment component 320. The output end of the horizontal angle adjustment component 310 is connected to the telescopic pipe 200. By driving the horizontal angle adjustment component 310, the horizontal angle of the telescopic pipe 200 can be adjusted, that is, the telescopic pipe 200 can be driven to rotate around the construction vessel 100. The output end of the horizontal distance adjustment component 320 is connected to the telescopic pipe 200. By driving the horizontal distance adjustment component 320, the horizontal distance between the discharge port of the telescopic pipe 200 and the construction vessel 100 can be adjusted.

[0056] By using the horizontal angle adjustment component 310 and the horizontal distance adjustment component 320 together, the outlet of the adhesive material is positioned directly above the pouring point.

[0057] After the outlet of the cementitious material is positioned directly above the pouring point, the extension and retraction of the telescopic pipe 200 is adjusted to ensure that the distance between the outlet of the cementitious material and the pouring point is within a preset range. This prevents the cementitious material from being too far apart from the pouring point, which would cause it to be dispersed before falling to the pouring point, resulting in a reduced pouring effect. It also prevents the distance between the outlet and the pouring point from being too small, which could cause the pouring pipe to touch the bottom due to the swaying of the construction vessel, thus damaging the pouring device.

[0058] When using the underwater casting device of this application, the telescopic pipe 200 is initially positioned by moving the construction vessel 100; then, the telescopic pipe positioning system 300 adjusts the angle and horizontal distance of the telescopic pipe 200 to align the outlet of the cementing material with the casting point; then, the telescopic length of the telescopic pipe 200 is controlled to ensure that the distance between the outlet of the cementing material and the casting point is within a preset range. Finally, the cementing material is injected into the casting point through the grouting pipe 400, thus ensuring that the outlet of the cementing material is in the preset position, thereby improving the accuracy of the cementing material casting point. By using the telescopic pipe positioning system 300 and changing the telescopic length of the telescopic pipe 200, the casting point of the cementing material can be controlled in real time, solving the technical problems of uncontrollable and inaccurate casting point of existing cementing materials. Meanwhile, the telescopic pipe 200 plays a role in limiting and protecting the grouting pipe 400. The telescopic pipe 200 provides rigid structural support for the grouting pipe 400, preventing the long grouting pipe 400 from bending during construction and causing the outlet of the cementing material to shift, thereby further improving the accuracy of the pouring point of the cementing material.

[0059] It should be noted that in this embodiment, the telescopic pipe 200 can be used to transport stones. When transporting stones, the grouting system needs to be removed from the telescopic pipe 200. After the grouting system is removed from the telescopic pipe 200, the stones can be transported into the telescopic pipe 200.

[0060] In another embodiment, the telescopic tube 200 includes an inner telescopic tube 210, an outer telescopic tube 220, and a traction component 230. The outer telescopic tube 220 is movably sleeved outside the inner telescopic tube 210. The output end of the traction component 230 is connected to the outer telescopic tube 220. The traction component 230 is configured to traction the outer telescopic tube 220 to move up and down along the inner telescopic tube 210.

[0061] In this embodiment, the outer telescopic tube 220 is moved up and down around the inner telescopic tube 210 by the traction component 230. This is to change the length of the entire telescopic tube 200. It should be noted that in this embodiment, the end of the inner telescopic tube 210 away from the outer telescopic tube 220 forms the inlet of the telescopic tube 200, and the end of the outer telescopic tube 220 away from the inner telescopic tube 210 forms the outlet of the telescopic tube 200.

[0062] The traction assembly 230 includes a traction drive and a traction rope. The traction drive can be a winch. Specifically, a fixed pulley and a traction rope fixing point are arranged sequentially from top to bottom on the inner telescopic tube 210, and a fixed pulley is arranged on the outer telescopic tube 220. One end of the traction rope is fixed to the traction rope fixing point, and the other end of the traction rope passes through the fixed pulleys on the outer telescopic tube 220 and the inner telescopic tube 210 in sequence, and is connected to the traction drive. By pulling the traction rope with the traction drive, the outer telescopic tube 220 can be moved upward. By pulling and releasing the traction rope with the traction drive, the outer telescopic tube 220 will move downward due to gravity, thereby realizing the extension and retraction of the telescopic tube 200.

[0063] In other embodiments, the grouting system further includes a clamp 500; a limiting conduit 600 is connected to the end of the outer telescopic pipe 220 away from the inner telescopic pipe 210; one end of the grouting pipe 400 is disposed at the end of the inner telescopic pipe 210 away from the outer telescopic pipe 220 via the clamp 500, and the other end of the grouting pipe 400 passes through the inner telescopic pipe 210, the outer telescopic pipe 220 and the limiting conduit 600 in sequence.

[0064] In this embodiment, a limiting guide 600 is provided at the outlet of the telescopic pipe 200, that is, the limiting guide 600 is connected to the end of the outer telescopic pipe 220 away from the inner telescopic pipe 210, and a grouting pipe 400 is provided inside the telescopic pipe 200. A clamp 500 is provided at the inlet of the telescopic pipe 200, that is, the end of the inner telescopic pipe 210 away from the outer telescopic pipe 220. The clamp 500 fixes the grouting pipe 400 tightly, so that one end of the grouting pipe 400 is provided at the end of the inner telescopic pipe 210 away from the outer telescopic pipe 220 through the clamp 500, and the other end of the grouting pipe 400 passes through the telescopic pipe 200, that is, passes through the inner telescopic pipe 210, the outer telescopic pipe 220 and the limiting guide 600 in sequence.

[0065] The telescopic pipe 200 serves to limit and protect the grouting pipe 400. The telescopic pipe 200 provides rigid structural support for the grouting pipe 400, preventing the long grouting pipe 400 from bending during construction.

[0066] The limiting guide tube 600 can prevent the lower end of the grouting pipe 400 from shifting, deforming or bending, so that the grouting pipe 400 is accurately positioned. In specific use, the height of the lower port of the grouting pipe 400 from the surface of the rubble, the seabed surface or the seabed scour pit is within 2m. The height of the lower port of the grouting pipe 400 from the surface of the rubble, the seabed surface or the seabed scour pit is adjusted in real time by the traction component 230.

[0067] If the lower end of the grouting pipe 400 is more than 2m above the surface of the riprap body or the seabed, the telescopic length of the telescopic pipe 200 is adjusted in real time by the traction component 230, so that the telescopic pipe 200 is extended, that is, the outer telescopic pipe 220 moves downward. At this time, the lower end of the limiting guide pipe 600 will be located at the lower end of the discharge port of the grouting pipe 400, so that the limiting guide pipe 600 also becomes a pouring channel, which indirectly realizes the extension of the grouting pipe 400 and ensures the pouring quality of the cementing material.

[0068] When it is necessary to transport stone, the grouting pipe 400, clamp 500 and limiting guide pipe 600 are disassembled and transported through the telescopic pipe 200, thereby realizing the integrated construction or continuous construction of crushed stone throwing and cementing material pouring.

[0069] Specifically, the inner telescopic tube 210 and the outer telescopic tube 220 can be made of steel pipe, and the grouting pipe 400 can be made of steel pipe, PE pipe, or flexible hose. The inner diameter of the inner telescopic tube 210 and the outer telescopic tube 220 is larger than that of the grouting pipe 400, and the outer diameter of the inner telescopic tube 210 is slightly smaller than that of the outer telescopic tube 220. The diameter of the inner telescopic tube 210 and the outer telescopic tube 220 can be 0.5-2m, and the diameter of the grouting pipe 400 can be 0.2-0.6m. The outer diameter of the limiting conduit 600 is smaller than that of the outer telescopic tube 220, and the inner diameter of the limiting conduit 600 is slightly larger than that of the grouting pipe 400. The grouting pipe 400 can move freely in the sliding conduit.

[0070] Specifically, the clamp 500 includes a clamp and a connecting plate. The connecting plate is secured to the end of the inlet of the inner telescopic pipe 210. The outer wall of the connecting plate abuts against the inlet of the inner telescopic pipe 210, forming a seal on the inlet of the inner telescopic pipe 210. A through hole is provided on the connecting plate, and the clamp is fixed at the through hole. One end of the grouting pipe 400 is clamped by the clamp, and the other end of the grouting pipe 400 passes through the through hole on the connecting plate and sequentially passes through the inner telescopic pipe 210 and the outer telescopic pipe 220. It should be noted that this embodiment is only one specific embodiment of the clamp 500; other structures that can fix the other end of the grouting pipe 400 to the inlet of the inner telescopic pipe 210 are also possible.

[0071] In one embodiment, a buoyancy member 700 is provided inside the grouting pipe 400. The buoyancy member 700 is configured to move with the grouting material under the gravity of the grouting material inside the grouting pipe 400, so as to reduce the flow speed of the grouting material.

[0072] In this embodiment, a buoyancy component 700 is provided inside the grouting pipe 400. The buoyancy component 700 may be a buoyancy ball, a buoyancy plate, etc. The number of buoyancy balls and buoyancy plates can be set multiple times. The buoyancy component 700 enables the grouting material, such as the cementing material, to be poured into the pipe, reducing the gravity velocity of the cementing material flowing into the lower end of the grouting pipe 400. This prevents the cementing material from being dispersed and segregated due to water washing during the flow of the grouting pipe 400, and ensures the pouring quality of the cementing material in the water.

[0073] Specific references Figure 5 , Figure 6 and Figure 7 As shown, a buoyancy component 700 is first installed inside the grouting pipe 400. When grouting is to be performed, as... Figure 5 As shown, the grout will be above the buoyancy component 700; as the amount of grout increases, its weight will increase, and then the grout will press the buoyancy component 700 downwards, as... Figure 6 As shown, the grout enters the middle of the telescopic pipe 200 along with the buoyancy component 700; as the grout continues to increase, it will cause the buoyancy component 700 to be squeezed out of the outlet of the telescopic pipe 200, such as... Figure 7 As shown, the final grout will squeeze the buoyancy component 700 out of the outlet of the telescopic pipe 200. Therefore, the use of the buoyancy component 700 can realize the grouting material to be cast into a pipe and avoid the dispersion and segregation of the cementing material due to water washing during the flow of the grouting pipe 400.

[0074] When the grouting pipe 400 delivers the grouting material, the grouting material will first come into contact with the buoyancy component 700. Since the weight of the grouting material is small at the beginning of delivery, the buoyancy component 700 will restrict the downward flow of the grouting material. When the amount of cementing material delivered reaches a certain quantity, the weight is greater than the buoyancy of the buoyancy component 700. At this time, the cementing material will be poured into the pipe. On the one hand, this avoids the cementing material from being dispersed and segregated by water washing in the grouting pipe 400. On the other hand, it reduces the gravity velocity of the cementing material flowing into the lower end of the grouting pipe 400, preventing the cementing material from falling at a high speed to the surface of the rubble body, the seabed surface, or the seabed scour pit. This avoids the cementing material from being dispersed and segregated due to impact, thus ensuring the quality of the cementing material in the water.

[0075] In some embodiments, a protective agent pumping system 800 is also included. The protective agent pumping system 800 includes a storage tank 810, a pump 820, and a pumping pipe 830. The storage tank 810 is used to store the protective agent. The pump 820 is disposed inside the storage tank 810. One end of the pumping pipe 830 is connected to the pump 820, and the other end of the pumping pipe 830 is connected to the grouting pipe 400.

[0076] Specifically, a pumping pipe 830 interface is provided on the clamp 500, and the pumping pipe 830 passes through the pumping pipe 830 interface and connects to the grouting pipe 400.

[0077] The protective agent is a polymer material. The protective agent and the cementing material flow out from the lower port of the grouting pipe 400 at the same time. The protective agent forms a stable spatial flexible network in the construction water area at the outlet of the grouting pipe 400, which inhibits the dispersion and segregation of the fresh cementing material during the pouring process. In this embodiment, by adding a protective agent pumping system 800, the protective agent is delivered at the same time as the cementing material, which further improves the quality of the pouring.

[0078] In another possible embodiment, the horizontal angle adjustment assembly 310 includes a base 311 and a support beam 312. The base 311 is rotatably mounted on the construction vessel 100. One end of the support beam 312 is connected to the base 311, and the other end of the support beam 312 is hinged to the inner telescopic tube 210.

[0079] In this embodiment, the rotation axis of the base 311 is perpendicular to the construction vessel 100. By rotating the base 311, the telescopic pipe 200 can rotate around the construction vessel 100, thereby changing the horizontal angle of the telescopic pipe 200.

[0080] In other possible embodiments, the horizontal distance adjustment assembly 320 includes a telescopic drive disposed on the base 311, the output end of the telescopic drive being connected to the inner telescopic tube 210, and the telescopic drive being configured to drive the inner telescopic tube 210 to rotate about the hinge point between the inner telescopic tube 210 and the support beam 312.

[0081] In this embodiment, the telescopic drive component can be a hydraulic cylinder, a hydraulic jack, etc. By extending and retracting the telescopic drive component, the inner telescopic tube 210 is driven to rotate around the hinge point between the inner telescopic tube 210 and the support beam 312, thereby changing the horizontal distance between the outlet of the telescopic tube 200 and the construction vessel 100.

[0082] In one possible implementation, it also includes a hopper 1000 and a casting joint pipe 1100, with the outlet of the hopper 1000 connected to one end of the casting joint pipe 1100 and the other end of the casting joint pipe 1100 connected to the inlet of the grouting pipe 400.

[0083] In this embodiment, by adding a material collection hopper 1000, it is convenient to transport materials to the telescopic pipe 200 or the grouting pipe 400. When it is necessary to transport cement-based binder material, the cement-based binder material is transported to the material collection hopper 1000 and then transported to the inlet of the grouting pipe 400 through the casting joint pipe 1100.

[0084] In other embodiments, a stone-throwing connector pipe is also included, with the discharge port of the hopper 1000 connected to one end of the stone-throwing connector pipe and the other end of the stone-throwing connector pipe connected to the inlet of the telescopic pipe 200.

[0085] In this embodiment, when it is necessary to transport stones, the grouting pipe 400, clamp 500 and limiting guide 600 are disassembled and transported through the telescopic pipe 200, thereby increasing the transport diameter.

[0086] It should be noted that the port of the riprap joint pipe near the telescopic pipe 200 is matched with the inlet of the telescopic pipe 200, and the port of the casting joint pipe 1100 near the grouting pipe 400 is matched with the inlet of the grouting pipe 400. In other words, the diameter of the port of the riprap joint pipe near the telescopic pipe 200 is larger than the diameter of the port of the casting joint pipe 1100 near the grouting pipe 400.

[0087] In some possible embodiments, a mixing system 900 is also included, which includes a mixer 910 and a crane 920, both of which are mounted on the construction vessel 100. The mixer 910 is used to mix the cementing material, and the crane 920 is used to transport the cementing material into the collection hopper 1000.

[0088] In another embodiment, the mixing system 900 includes a pumping system that delivers the cementing material into the collection hopper 1000.

[0089] In this embodiment, the mixing system 900 enables rapid and continuous material delivery, improving casting efficiency and ensuring the continuity of cementitious material casting.

[0090] A second aspect of this application provides a method for casting underwater cementitious materials, using an underwater casting device, the method comprising:

[0091] The construction vessel 100 of the mobile underwater pouring device performs preliminary positioning of the telescopic pipe 200 of the underwater pouring device;

[0092] The telescopic pipe 200 is precisely positioned by the horizontal angle adjustment component 310 and the horizontal distance adjustment component 320 of the underwater pouring device so that the outlet of the cementing material is located directly above the pouring point.

[0093] Control the extension length of the telescopic tube 200 so that the distance between the outlet of the adhesive material and the pouring point is within a preset range;

[0094] The adhesive material is conveyed into the expansion pipe 200 so that it can be delivered to the pouring point.

[0095] It should be noted that the bonding material is an underwater self-protecting cement-based bonding material. When using the underwater bonding material pouring method of this embodiment, the preliminary positioning of the telescopic pipe 200 by the construction vessel 100 and the precise positioning of the telescopic pipe 200 by the telescopic pipe positioning system 300 ensures that the outlet of the bonding material is aligned with the pouring point. Furthermore, by controlling the extension length of the telescopic pipe 200, the distance between the outlet of the bonding material and the pouring point is kept within a preset range, thereby improving the accuracy of the pouring point. By using the telescopic pipe positioning system 300 and changing the extension length of the telescopic pipe 200, the pouring point can be controlled in real time, solving the technical problems of uncontrollable and inaccurate pouring points in existing bonding materials, and ensuring the quality and continuity of the pouring process.

[0096] The underwater cementitious material pouring method, before conveying the cementitious material into the expansion pipe 200 to the pouring point, also includes:

[0097] Place the buoyancy component 700 into the grouting pipe 400.

[0098] The protective agent is delivered into the grouting pipe 400.

[0099] Because a buoyancy component 700 is placed inside the grouting pipe 400 to transport the protective agent and self-protecting cement-based binder, the falling velocity of the underwater self-protecting binder flowing from the lower end of the grouting pipe 400 can be reduced, thus preventing the underwater self-protecting binder from dispersing and segregating due to water washing during the flow of the grouting pipe 400, and ensuring the casting quality of the binder in water.

[0100] The protective agent forms a stable spatial flexible network in the construction water area of ​​the grouting pipe 400 and at the outlet of the grouting pipe 400, which inhibits the dispersion and segregation of fresh cement-based binder during the pouring process and further improves the stability of the pouring.

[0101] By using the underwater bonding material casting construction method of this application, the casting and positioning of the underwater self-protecting bonding material is more precise, and the continuity of the underwater self-protecting bonding material transportation is ensured, avoiding the dispersion and segregation of the underwater self-protecting bonding material and ensuring the casting quality of the underwater self-protecting bonding material in water.

[0102] In some possible embodiments, before the telescopic pipe 200 is precisely positioned by the horizontal angle adjustment component 310 and the horizontal distance adjustment component 320 of the underwater casting device so that the outlet of the cementing material is located directly above the casting point, the method further includes, based on GPS data and water depth data, precisely positioning the casting point and the position of the lower port of the grouting pipe 400 from the surface of the riprap or the seabed.

[0103] This application also provides an underwater rock-casting construction method, including the use of an underwater casting device, the method comprising:

[0104] Disassemble the grouting pipe 400, clamp 500 and limiting guide pipe 600, and connect the stone throwing joint pipe between the feed inlet of the aggregate hopper 1000 and the telescopic pipe 200.

[0105] According to the design requirements, based on GPS data and water depth data, the location of the rock-throwing point and the distance between the 200mm outlet of the telescopic pipe and the seabed or the bottom of the scour pit should be accurately determined.

[0106] The telescopic pipe 200 is precisely positioned by the telescopic pipe positioning system 300 so that the telescopic pipe 200 is located directly above the stone throwing point.

[0107] Control the extension length of the telescopic pipe 200 so that the distance between the outlet of the telescopic pipe 200 and the stone throwing point is within a preset range.

[0108] The riprap material is transported to the collection hopper 1000 by the crane 920. Under its own weight, the riprap is thrown and filled into the seabed or scour pit along the telescopic pipe 200.
