DETAILED DESCRIPTION

[0034] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0035] In this disclosure, unless otherwise stated, directional words such as "upper, lower, left, right" are used for the convenience of description and are defined according to the drawing direction of the corresponding drawings, and "inside, outside" are defined according to the contours of the corresponding parts. Terms such as "first, second" and the like used in this disclosure are used to distinguish one element from another and do not have order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] Offshore artificial islands have positive significance for the development of offshore oil and gas platforms, offshore cultural tourism, hydrogen and ammonia production industries to go deep into the sea, and explore the use of marine resources. At present, the island formation schemes for offshore artificial islands mainly include the cofferdam dumping method, the steel cylinder cofferdam rapid island formation method, and the method of enclosing the sea first and then filling. The above methods all require the use of backfill materials for filling. The backfill materials are prone to settlement and uneven settlement, posing a threat to the safety of buildings and structures on the island. Engineering personnel need to use soft soil foundation treatment methods to carry out necessary reinforcement and improvement of the foundation, improve the bearing capacity of the foundation, and ensure the stability of the foundation. However, this leads to a large amount of offshore engineering and a long island construction period.

[0037] Therefore, the embodiments of the present disclosure provide an artificial island to reduce the offshore engineering workload and island construction period of the artificial island. Figures 1 to 3 as well as Figure 5 The artificial island may include a caisson module 100, and the caisson module 100 may include a box body 110, a pile 300 and a liquid-passing assembly 200. Among them, the box body 110 may be provided with a receiving chamber 113. The pile 300 may be connected to the bottom of the box body 110. The liquid-passing assembly 200 may be in communication with the receiving chamber 113, and is configured to: when liquid is injected into the receiving chamber 113, the box body 110 and the pile 300 are sunk, so that the pile 300 is inserted into the seabed; when the liquid in the receiving chamber 113 is discharged, the box body 110 and the pile 300 are floated. The water here may be untreated seawater or desalinated seawater, etc., or other liquid resources. The desalinated seawater can prevent the rust of the components in the box body 110. It is relatively easy to obtain seawater, which facilitates the construction of the artificial island.

[0038] It is understandable that the caisson module 100 can be constructed in a unified modular manner on land, reducing the construction period at sea. The caisson module 100 is transferred to the predetermined sea area by a tugboat, and the liquid-passing assembly 200 can inject liquid into the accommodating chamber 113, so that the box body 110 filled with water drives the pile 300 to sink until the pile 300 is inserted into the seabed. The force between the pile 300 and the seabed can prevent the caisson module 100 from floating. At the same time, the bottom of the box body 110 can contact the seabed, and the friction between the two can prevent the artificial island from drifting. The box body 110 has a certain structural strength, which ensures the stability of the foundation of the workers' island. The space in the accommodating chamber 113 is filled with water. The artificial island of the embodiment of the present disclosure does not need backfilling materials, which reduces the offshore engineering volume and construction period. The caisson module 100 relies on increasing the liquid in the accommodating chamber 113 to enable the pile 300 to be inserted into the seabed. Therefore, there is no need to drive piles during the construction process, avoiding environmental damage to the seabed caused by driving piles, reducing the difficulty of construction and the impact on navigation and fisheries. The entire set of manufacturing and installation processes is efficient, economical, and environmentally friendly, reducing the impact on the ecological environment to a minimum, and reducing the project cycle and project costs. When the artificial island needs to be transferred, the liquid-passing component 200 can discharge the seawater in the accommodating chamber 113, reducing the amount of water in the accommodating chamber 113, so that the box body 110 can drive the pile 300 to float, which is convenient for the recycling and reuse of the caisson module 100.

[0039] In one embodiment, see Figure 5 and Figure 6 The accommodating chamber 113 may be provided with a plurality of partition plates 120 spaced apart from each other in an upper and lower direction. The partition plates 120 may divide the accommodating chamber 113 into a plurality of water chambers 1131 separated from each other in an upper and lower direction. The liquid-passing assembly 200 may be used to inject liquid into the plurality of water chambers 1131 respectively, and may be used to discharge the liquid in the plurality of water chambers 1131 respectively. When one of the plurality of water chambers 1131 is damaged, the remaining water chambers 1131 may still be used to accommodate water, so as to ensure that the caisson module 100 can sink or float normally.

[0040] It is understandable that the multiple water chambers 1131 can be named as the first water chamber, the second water chamber, ... the Nth water chamber from bottom to top, respectively. The liquid-passing assembly 200 can first fill the first water chamber with water to make the center of gravity of the box body 110 lower, ensuring that the box body 110 can sink stably. When the first water chamber is filled with water, the sinking speed of the caisson module 100 is observed. If it sinks too slowly, the second water chamber is filled with water to ensure that the caisson module 100 can sink relatively slowly and stably. Workers can measure the amount of water entering the box body 110 in units of one water chamber 1131, and then calculate the sinking speed of the caisson module 100 according to the amount of water injected, ensuring that the caisson module 100 can sink relatively slowly and stably.

[0041] In one embodiment, see Figure 5 and Figure 6The liquid passage assembly 200 may include a main pipe 210, a pressure drainage pump, a plurality of branch pipes 220 and a plurality of valves. The pressure drainage pump may be installed on the main pipe 210 and may be arranged in a liquid storage source. The liquid storage source here may refer to the sea or to a liquid storage container arranged separately. The plurality of branch pipes 220 may be respectively connected to the main pipe 210 and may be connected to the plurality of water chambers 1131 one by one, so as to be used for supplying or draining liquid to the plurality of water chambers 1131. The plurality of valves may be installed on the plurality of branch pipes 220 one by one, so as to facilitate controlling the water inlet or water outlet of each water chamber 1131 one by one.

[0042] In one embodiment, see Figure 5 and Figure 6 The main pipe 210 can pass through each water cavity 1131, and each branch pipe 220 can be respectively arranged in each water cavity 1131. The valve can be a solenoid valve, and the valve plate of the solenoid valve is controlled by the circuit system to open, so that the water in the main pipe 210 can enter the designated branch pipe 220. The water entering each water cavity 1131 shares a main pipe 210 that passes through each water cavity 1131, so the length of each branch pipe 220 in the box body 110 can be shorter, which is conducive to saving the use of the branch pipe 220.

[0043] For further information, see Figure 5 and Figure 6 The number of the main pipes 210 can be two, and both of them run through each water cavity 1131. One of the two main pipes 210 can be responsible for water intake, and the other can be responsible for drainage, so as to simplify the control. Of course, in other embodiments, the two main pipes 210 can intake or drain water together.

[0044] In another embodiment, the water inlet end of each branch pipe 220 is located outside the box body 110, so the valve can be a manual valve, and by opening a designated manual valve, water can enter the designated water chamber 1131 through the branch pipe 220 on the designated manual valve. There is no need to use a solenoid valve, thus avoiding the need for a circuit system for the valve body.

[0045] In one embodiment, see Figure 6 and Figure 7 , a through hole 111 may be provided at the bottom of the box body 110 near the pile 300. The caisson module 100 may also include a main pipeline 410 and a high-pressure pump. The main pipeline 410 may extend into the accommodating chamber 113 and may extend along the bottom wall of the accommodating chamber 113, and the liquid outlet of the main pipeline 410 may be connected to the through hole 111. The high-pressure pump may be installed in the main pipeline 410 and may be arranged in a liquid storage source, where the liquid storage source may be the same as that described above, and the accommodating chamber 113 storing liquid may also be configured as a liquid storage source.

[0046] It is understandable that when the caisson module 100 needs to float, the high-pressure pump is started, so that high-pressure water passes through the main pipeline 410 and acts on the seabed around the piles 300, thereby making the soil around the piles 300 relatively soft, thereby increasing the speed of pulling the piles 300 out of the seabed, thereby increasing the transfer speed of the artificial island.

[0047] In one embodiment, see Figure 5 and Figure 7 , the number of piles 300 can be multiple, and they can be arranged at intervals at the bottom of the box 110. The force between the multiple piles 300 and the seabed is relatively large, ensuring that the artificial island will not move under the impact of waves. The number of through holes 111 can be multiple, and they can be arranged in a one-to-one correspondence with the multiple piles 300. The caisson module 100 can also include a plurality of branch pipes 420 respectively connected to the main pipe 410, and the multiple branch pipes 420 can be inserted into the multiple through holes 111 in a one-to-one correspondence. After passing through the main pipe 410 and the branch pipes 420, the water acts on the seabed around the piles 300, ensuring that the piles 300 can be pulled out synchronously and as quickly as possible, thereby increasing the floating speed of the caisson module 100 and ensuring that the caisson module 100 does not tilt during the pulling out process.

[0048] For further information, see Figure 5 The number of the main pipes 410 can be two, and the two main pipes 410 can extend along both sides of the bottom wall of the accommodating chamber 113, and are respectively connected to the multiple branch pipes 420 on the side in a one-to-one correspondence, and the two main pipes 410 can be filled with high-pressure water at the same time.

[0049] In one embodiment, see Figure 5 and Figure 7 The box body 110 can be constructed as a triangular prism, so that multiple caisson modules 100 can be assembled to form artificial islands of various shapes. Of course, in other embodiments, the box body 110 can be constructed as a cylinder or a cuboid.

[0050] In one embodiment, see Figure 7 The pile 300 can be constructed as a multi-prism to prevent the pile 300 from rotating in the seabed, thereby ensuring the stability and reliability of the caisson module 100 after sinking.

[0051] In one embodiment, the box 110 and the piles 300 can be made of concrete in one piece. The concrete product has a certain structural strength to support the subsequent construction on the island. The box 110 is evenly stressed as a whole, and there is no need to reinforce or improve the box 110, which reduces the amount of offshore engineering and the island construction period, and reduces the construction difficulty and cost. At the same time, the concrete product can prevent corrosion, preventing the caisson module 100 from being corroded by being immersed in seawater for a long time.

[0052] In one embodiment, see Figures 1 to 3 as well as Figure 5 , a skirt 112 may extend outwardly from the bottom circumference of the box body 110, and the skirt 112 may be configured such that when the pile 300 is inserted into the seabed, the skirt 112 contacts the seabed. The skirt 112 may be in the shape of a straight plate, and the skirt 112, the box body 110 and the pile 300 may be integrally made of concrete. If the artificial island includes only one caisson module 100, the circumference of the bottom of the box body 110 of the caisson module 100 is provided with a skirt 112; if the artificial island includes multiple caisson modules 100, the outer circumference of the bottom of the caisson module 100 located at the periphery of the artificial island is provided with a skirt 112, and the inner circumference thereof is not provided with a skirt 112.

[0053] It is understandable that after the artificial island is built, the seawater will form vortices or eddies around the seabed of the artificial island, increasing the shear stress of the water flow on the seabed, resulting in an increase in the sand-carrying capacity of the water flow, thereby causing the seabed to be eroded, affecting the stability of the artificial island. The skirt 112 is provided to prevent the seawater from forming eddies around the box 110, thereby ensuring that the foundation of the artificial island will not be eroded or washed away, thereby ensuring the stability and reliability of the artificial island, and having a strong ability to resist natural disasters after the island is built.

[0054] In one embodiment, a plurality of support columns may be provided inside the caisson module 100 , some of which may be arranged horizontally, and other support columns may be arranged vertically, thereby enhancing the structural strength of the box body 110 and preventing the box body 110 from collapsing.

[0055] In one embodiment, see Figures 1 to 3 The artificial island may include a plurality of caisson modules 100, and two adjacent caisson modules 100 may be detachably spliced ​​in the horizontal direction, so that the caisson modules 100 may be individually transferred to the designated sea area of ​​the island, thereby reducing the workload of the tugboat.

[0056] It should be noted that this solution can be applied to different seabed soil conditions and is easy to construct. For example, when building an artificial island on a hard seabed, the hard seabed can provide a stable support force for the box 110. At the same time, because the box 110 has a certain structural strength, the overall force of the artificial island is uniform and will not move. For example, when building an artificial island on a soft soil seabed, the spliced ​​artificial island is equivalent to a whole, and there will be no local downward movement, which ensures that the building on the box 110 will not tilt.

[0057] In another embodiment, a plurality of caisson modules 100 may be enclosed to form a fence around the artificial island, and the artificial island may be constructed by backfilling the fence with materials.

[0058] In one embodiment, see Figures 1 to 4The caisson module 100 may be provided with an ear plate 510, and the ear plate 510 may be provided with an ear hole. Two adjacent caisson modules 100 may be detachably connected by a connecting piece 520 that respectively passes through the two ear holes. When two caisson modules 100 need to be connected, the ear holes of the two ear plates 510 are placed on the same axis, and the connecting piece 520 passes through the two ear holes. The connecting piece 520 is pushed upward to leave the two ear holes, so that the two caisson modules 100 are separated. The connecting piece 520 may be a pin shaft or a bolt, etc.

[0059] Furthermore, there may be multiple ear plates 510, which may be spaced and distributed around the circumference of the box body 110, and there may be multiple connectors 520, which may be arranged one-to-one with multiple ear plates 510. The arrangement of multiple ear plates 510 and multiple connectors 520 can ensure the stable connection of two adjacent caisson modules 100.

[0060] See also Figures 1 to 8 According to the second aspect of the embodiment of the present disclosure, a method for sinking an artificial island is provided, which is applied to an artificial island according to any one of the above embodiments. The artificial island may include one or more caisson modules 100. For example, the number of caisson modules 100 may be three, four, or more than five. The engineering personnel may select the number of caisson modules 100 and the shape of the caisson modules 100 after splicing according to the area of ​​the island demarcation area, thereby ensuring the construction of large, medium, and small artificial islands. The way of splicing into an island can facilitate the designer to expand the scale of the artificial island as needed later. The sinking method of multiple caisson modules 100 may include: Step S810, after the first caisson module 100 is transferred to a preset position, liquid is injected into the accommodating cavity 113 of the first caisson module 100, so that the first caisson module 100 is sunk until it is inserted into the seabed.

[0061] Step S830, transfer the second caisson module 100 to a position corresponding to the side of the first caisson module 100, that is, to a position above the side of the first caisson module 100, so that it can be located beside the first caisson module 100 after sinking.

[0062] Step S850, injecting liquid into the accommodating cavity 113 of the second caisson module 100, so that the second caisson module 100 is sunk to be inserted into the seabed, and the second caisson module 100 is detachably connected to the first caisson module 100.

[0063] Step S870, and so on, multiple caisson modules 100 are spliced ​​together to form an artificial island.

[0064] The sinking method of the artificial island can have all the beneficial effects of the above-mentioned artificial island, which will not be repeated here.

[0065] It is understandable that before sinking the artificial island, the seabed of the island demarcation area is leveled to avoid damage to the caisson module 100 after sinking due to uneven force, so as to ensure the stability and reliability of the artificial island. The liquid-passing assembly 200 of the first caisson module 100 can inject liquid into the accommodating chamber 113 of the box body 110 to sink the first caisson module 100, so that the pile 300 of the first caisson module 100 is inserted into the seabed. At this time, the top of the box body 110 of the first caisson module 100 is still above the sea level. A temporary winch is arranged on the top, and the second caisson module 100 is towed and adjusted by the winch, so that the second caisson module 100 is close to the first caisson module 100, so that the ear plate 510 of the second caisson module 100 is located above the side of the ear plate 510 of the first caisson module 100. The liquid-passing assembly 200 of the second caisson module 100 can inject liquid into the accommodating chamber 113 of the box body 110 to make the second caisson module 100 sink, so that the pile 300 of the second caisson module 100 is inserted into the seabed. The connecting piece 520 is passed through the ear holes of the two ear plates 510 so that the two caisson modules 100 can be connected and fixed. By analogy, multiple caisson modules 100 can be spliced ​​to form an artificial island.

[0066] In one embodiment, see Figure 6 The accommodating chamber 113 may include a plurality of water chambers 1131 separated from each other in an upper and lower manner. The step of injecting liquid into the accommodating chamber 113 of the caisson module 100 may include injecting liquid into the plurality of water chambers 1131 in a sequence from bottom to top.

[0067] It is understandable that the multiple water chambers 1131 in a box 110 are named the first water chamber, the second water chamber, and the Nth water chamber from bottom to top. The liquid-passing assembly 200 can first fill the first water chamber with water to make the center of gravity of the box 110 lower and ensure that the box 110 can sink stably. When the first water chamber is filled with water, the sinking speed of the caisson module 100 is observed. If it sinks too slowly, the second water chamber is filled with water to ensure that the caisson module 100 can sink relatively slowly and stably. Workers can measure the water intake of the box 110 in units of a water chamber 1131, and then calculate the sinking speed of the caisson module 100 according to the water injection amount to ensure that the caisson module 100 can sink relatively slowly and stably.

[0068] In one embodiment, the combination of the box 110, the piles 300 and the skirt 112 can be constructed in batches using a standardized, modular unified design, which improves the casting efficiency and cost of the combination. After the island is formed, the engineering personnel can directly install facilities on the top of the box 110 without the need to arrange an additional deck for support. The concrete cast box 110 has good self-stability. The draft of the box 110 is adjusted by the liquid-passing assembly 200 so that the draft of the box 110 is the same as the draft of the tugboat. The draft refers to the height of the box 110 or the tugboat extending into the sea level, which is convenient for the tugboat to drag the caisson module 100 to the designated area of ​​the island.

[0069] See also Figures 1 to 7 as well as Fig. 9 According to a third aspect of an embodiment of the present disclosure, a method for floating an artificial island is provided, which is applied to an artificial island according to any one of the above embodiments. The artificial island may include a plurality of caisson modules 100. The method for floating an artificial island includes: Step S910: dismantle and separate the first caisson module 100 and its adjacent caisson modules 100.

[0070] Step S930, draining the liquid in the accommodating cavity 113 of the first caisson module 100 to make the first caisson module 100 float.

[0071] Step S950, and so on, making multiple caisson modules 100 float up respectively.

[0072] The floating method of the artificial island can have all the beneficial effects of the above-mentioned artificial island, which will not be repeated here.

[0073] It is understandable that the connecting piece 520 between the first caisson module 100 and its adjacent caisson module 100 is removed, and the liquid passing assembly 200 of the first caisson module 100 is started to discharge the liquid in the accommodating cavity 113 of the box body 110, so that the box body 110 drives the pile 300 to float up. In this way, multiple caisson modules 100 are floated up respectively.

[0074] In one embodiment, see Figure 6 The accommodating chamber 113 may include a plurality of water chambers 1131 separated from each other in an upper and lower manner. The step of discharging the liquid in the accommodating chamber 113 of the caisson module 100 may include: discharging the liquid in the plurality of water chambers 1131 in a sequence from top to bottom.

[0075] It is understandable that the multiple water chambers 1131 in a box 110 can be named as the first water chamber, the second water chamber...the Nth water chamber from bottom to top, respectively. The liquid-passing assembly 200 can first drain the Nth water chamber to ensure that the caisson module 100 can have a lower center of gravity. After the Nth water chamber is emptied of liquid, the floating speed of the caisson module 100 is observed. If it floats too slowly, the N-1th water chamber is drained to ensure that the caisson module 100 can float relatively slowly and stably. Workers can measure the drainage volume of the box 110 in units of a water chamber 1131, and then calculate the sinking speed of the caisson module 100 according to the water injection volume to ensure that the caisson module 100 can sink relatively slowly and stably.

[0076] In one embodiment, see Figure 5 and Figure 6 The caisson module 100 may include a pile punching assembly. Before the step of discharging the liquid in the accommodating chamber 113 of the caisson module 100, the floating method may include: The pile driving assembly sprays high pressure water onto the seabed around the pile 300 .

[0077] It is understandable that when the artificial island needs to be transferred, the pile punching assembly sprays water around the piles 300 to release the limit of the piles 300 on the seabed, so as to facilitate the transfer and reuse of the artificial island.

[0078] The pile driving assembly may include a main pipeline 410 and a high-pressure pump installed on the main pipeline 410. A through hole 111 is provided at the bottom of the box body 110 near the pile 300. The water outlet end of the main pipeline 410 can pass through the through hole 111. The high-pressure pump is started, and the liquid forms high-pressure water after passing through the high-pressure pump. The high-pressure water acts on the seabed around the pile 300 after passing through the water outlet end of the main pipeline 410.

[0079] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0080] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0081] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
