Description

Technical Field

[0001] The present application relates to the technical field of caissons, and in particular to an assembled marine suction caisson foundation structure and a construction method thereof. Background Art

[0002] A suction caisson is a box-shaped structure with a closed top and an open bottom (or part of the side). Relying on its own gravity and internal pumping of water and air to form a negative pressure suction, the caisson is gradually "sucked" into seabed strata such as marine soil, soft clay, and sandy soil, and eventually sits stably at a predetermined depth on the seabed, providing a supporting structure with vertical bearing, pullout resistance, and resistance to horizontal loads for offshore wind power foundations, cross-sea bridge piers, and offshore platforms.

[0003] Suction caisson foundations are widely used in projects such as cross-sea bridges, offshore wind power, and offshore platforms due to their advantages such as convenient construction and minimal disturbance to the marine environment. However, traditional designs focus on structural mechanical properties and ignore the needs of marine ecological restoration: the large-scale construction of marine engineering facilities has destroyed the original habitat and breeding environment of marine organisms, resulting in a decrease in biodiversity in local sea areas.

[0004] Therefore, it is necessary to provide an assembled marine suction caisson foundation structure and a construction method thereof to solve the above problems. Summary of the Invention

[0005] Based on the above-mentioned problems existing in the prior art, the problem to be solved by this application is: to provide an assembled marine suction caisson foundation structure and a construction method thereof, so as to achieve the effect of protecting marine animals on the outside of the caisson, thereby solving the problem of the surrounding ecological environment.

[0006] The technical solution adopted by this application to solve its technical problems is: an assembled marine suction caisson foundation structure, including a caisson assembly, the caisson assembly includes several groups of assembled box bodies, the interior of the box bodies is fixedly installed with steel bars, the interior of the box bodies is fixedly installed with an escalator, the box bodies are provided with openings, the bottom of the box bodies is provided with an oblique opening, and the outside of the caisson assembly is provided with a bionic component for repairing the marine ecological environment.

[0007] Furthermore, the bionic component includes a bionic plate arranged on the box body, and the bionic plate is provided with a plurality of groups of holes.

[0008] Furthermore, a fixing frame adapted to the bionic board is fixedly mounted on the box body, and a draw hook is fixedly mounted on the end of the bionic board.

[0009] Furthermore, a rolling groove is provided on the inner bottom of the fixing frame, a roller is movably mounted on the rolling groove, and the bottom of the bionic board can contact the roller.

[0010] Furthermore, clamping strips are fixedly mounted on both ends of the fixing frame, and the connecting parts of the clamping strips and the fixing frame can be connected by bolts. A protrusion is fixedly mounted on the clamping strip, and the protrusion can be close to the side of the bionic board.

[0011] Furthermore, side bars a and side bars b are fixedly mounted on both ends of the box body, and grooves that match the side bars a are formed on the side bars b.

[0012] Furthermore, a clamping block is fixedly installed on the bottom of the side strip a, and a clamping slot that is adapted to the clamping block is provided above the side strip a.

[0013] A method for constructing an assembled marine suction caisson comprises the following steps:

[0014] S1: In a factory environment, prefabricated boxes are mass-produced according to design specifications. During the casting process of the box, steel bars are accurately embedded or welded at key stress-bearing locations to enhance structural strength and ensure that the grooves on the side bars b precisely fit with the side bars a. At the same time, openings are opened on the top of the box for fixing lifting equipment, and the bottom is processed with an outward-expanding bevel to optimize the sinking performance. Then, a fixing frame is fixed to the outside of the box, a rolling groove is opened on the inner bottom, and rollers are installed in the rolling groove to complete the basic prefabrication of the caisson assembly.

[0015] S2: Independently prefabricate the bionic board, open holes of gradient size on its surface, and fix hooks on the ends. Fix the card strips to both ends of the fixed frame with bolts, and then install bumps on the card strips to complete the assembly of the bionic component and set it aside.

[0016] S3: Prepare construction equipment such as crane vessels, tugboats, air bags, vacuum pumps, etc., check the specifications and quality of materials such as lifting rigging and bolt connectors to ensure that they meet the design requirements, and formulate a detailed construction safety plan based on the construction sea environment.

[0017] S4: Use lifting equipment such as crane ships to lift and fix the prefabricated caisson components through the openings, and transport them steadily to the designated location near the construction sea area. This method is suitable for long-distance and deep-water transportation, and can ensure the integrity and stability of the caisson components during transportation.

[0018] S5: When the caisson assembly is close to the coast or in a shallow area, an external air bag is placed at the bottom of the caisson assembly. After it is inflated, the caisson is lifted up. A tugboat or shore traction equipment is used to pull the caisson assembly through the air bag and roll it to the vicinity of the construction site, taking advantage of the friction-reducing feature of the oblique opening at the bottom of the caisson, thereby reducing the difficulty and cost of transportation in shallow water areas.

[0019] S6: After the caisson assembly is precisely positioned at the designed installation location, the airbag is deflated or the lifting equipment is released to allow the caisson to drop steadily to the seabed. The vacuum pump is started to pump out the air inside the caisson to create negative pressure. The suction principle is used in conjunction with the oblique opening at the bottom of the caisson to guide the cutting into the foundation soil, allowing the caisson assembly to sink quickly and steadily to the predetermined depth. During this process, the verticality and sinking depth of the caisson are monitored in real time to ensure installation accuracy.

[0020] S7: After a single caisson assembly is sunk into place, the grooves of the side bars a and b of the adjacent caissons are aligned with each other through mechanical assistance or manual fine-tuning to complete the splicing of the transverse caisson assembly to form a stable plane array structure and enhance the overall resistance to horizontal loads.

[0021] S8: Use a small lifting device or a robotic arm to lift the bionic board through the hook at the end of the board and move it to the fixed frame outside the box, so that the bottom of the bionic board contacts the roller in the fixed frame. With the help of the roller rolling in the rolling groove, the bionic board is pushed to slide along the fixed frame to the installation position. When the bionic board is completely inserted into the fixed frame, the protrusion on the card strip is in close contact with the side of the bionic board, and the elastic deformation of the protrusion is used to produce a limiting effect to prevent the bionic board from displacement.

[0022] S9: After checking that the bionic board is installed in the correct position, tighten the bolts connecting the clips and the fixing frame to ensure that the bionic component is firmly installed. According to actual needs, the height of the bionic board in the fixing frame can be adjusted to place it in a suitable position in the seawater to achieve the best ecological function.

[0023] The beneficial effects of this application are:

[0024] The present application provides an assembled marine suction caisson foundation structure, which can enter the sea together with the box body through a bionic plate, so that the holes can come into contact with seawater. In this way, the bionic plate can simulate the reef environment through the holes, provide a habitat for marine life, build a food chain, repair the ecological chain, and enhance biodiversity. In engineering, it can also weaken wave force, reduce base scouring, and reduce structural fatigue damage. At the same time, biological attachment forms a protective layer to improve the durability of the caisson.

[0025] The present application provides an assembled marine suction caisson foundation structure, which enables a bionic board to be installed on the box body through a fixed frame, and ensures stable positioning of the bionic board through the clips on both sides. Finally, the bionic board can contact the roller when installed on the clips, thereby improving the smoothness of the bionic board during installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0040] like Figure 1-Figure 7As shown, the present application provides an assembled marine suction caisson foundation structure and a construction method thereof, including a caisson assembly 10, and a bionic assembly 20 fixedly installed on the outside of the caisson assembly 10, wherein the caisson assembly 10 is used to provide a support structure for vertical bearing, pull-out resistance and horizontal load resistance for offshore wind power foundations, cross-sea bridge piers, marine platforms, etc., and the bionic assembly 20 is used to repair the marine ecological environment, thereby improving the habitat and reproduction of marine organisms and reducing local marine biodiversity.

[0041] The caisson assembly 10 includes several groups of assembled boxes 11, on which steel bars 12 are fixedly installed. The caisson assembly 10 as a whole can contact external lifting equipment during installation, or contact the bottom of the caisson assembly 10 through an external air bag, so that the caisson assembly 10 can be rolled to the vicinity of the coast through the air bag. The steel bars 12 are pre-embedded or welded to key stress-bearing parts inside and on the surface of the box 11, thereby improving the overall strength and deformation resistance of the box 11, reducing the risk of structural cracks and damage, and extending the service life of the caisson assembly 10.

[0042] Both ends of the box body 11 are fixedly installed with side strips a13 and side strips b14. At the same time, the side strips b14 are provided with grooves that are compatible with the side strips a13. When two horizontal caisson assemblies 10 need to be assembled and spliced, the side strips a13 can be aligned with the grooves of the side strips b14, so that the caisson assemblies 10 between the horizontal sides can be installed. This design provides a precise docking structure for the splicing of the horizontal caisson assemblies 10, ensuring that the splicing process is efficient and accurate.

[0043] At the same time, a clamping block 15 is fixedly installed at the bottom of the side bar a13, and a clamping groove 16 is opened on the top of the side bar a13 to adapt to the clamping block 15. When the upper and lower boxes 11 are assembled and spliced, the clamping block 15 of the upper box 11 can enter the lower clamping groove 16, and the boxes 11 can be aligned up and down during assembly;

[0044] During installation, the advantages of the prefabricated design were demonstrated. Not only did the boxes 11 achieve rapid vertical splicing via the clamping blocks 15 and the slots 16, but adjacent caisson assemblies 10 could also be precisely assembled by aligning the side bars a13 with the grooves of the side bars b14, forming a stable planar array structure. This vertical and horizontal bidirectional splicing method improves construction efficiency compared to traditional cast-in-place structures, while also reducing offshore operation time and construction risks. Furthermore, after horizontal splicing, the grooves of the side bars a13 and b14 cooperate to form a continuous force transmission path, enhancing the caisson's overall ability to resist horizontal loads such as currents and wave impact, and improving structural stability.

[0045] An opening 17 is provided on the box body 11, and the opening 17 can provide a fixed position for the external lifting equipment. The hook or sling of the external lifting equipment passes through the opening 17 and is fixed to lift the caisson assembly 10 as a whole. The lifting method fixed by the opening 17 has stronger stability and reliability than relying solely on the top surface of the box body 11 for fixation.

[0046] At the same time, an escalator 18 is fixedly installed inside the box 11, and the length of the escalator 18 can be changed according to the length of the box 11.

[0047] In addition, an oblique opening 19 is provided at the bottom of the box 11. The inclined setting of the oblique opening 19 can effectively guide the box 11 to cut into the foundation soil, reduce the sinking resistance, and at the same time reduce the risk of deviation caused by uneven force during the sinking process, so that the box 11 can reach the designed position more accurately.

[0048] The bionic component 20 includes a bionic plate 21 arranged on the box 11. At the same time, the installation position of the bionic plate 21 can be adjusted according to the depth of the box 11 entering the foundation, so that the bionic plate 21 can be located in a suitable position in the seawater, ensuring that the several groups of holes 22 opened thereon are always in the best biological habitat environment. In addition, several groups of holes 22 are opened on the bionic plate 21, and the holes 22 can form a three-dimensional space to meet the needs of marine organisms at different growth stages. In addition, the holes 22 on the bionic plate 21 can also optimize the hydrodynamic environment around the box 11, disperse wave energy, further reduce the wave force on the box 11, and achieve a synergistic improvement of ecological functions and engineering performance.

[0049] The box 11 is fixedly mounted with a fixing frame 24, which can be adapted to the bionic board 21 and provide a stable support structure for the installation of the bionic board 21, so that the bionic board 21 can be smoothly installed on the box 11 through the fixing frame 24. At the same time, a hook 23 is fixedly mounted on the end of the bionic board 21, and the hook 23 can contact with an external lifting device, so that the bionic board 21 can be installed faster through the hook 23.

[0050] A rolling groove 27 is formed at the inner bottom of the fixing frame 24, and a roller 28 is movably mounted on the rolling groove 27. When the bionic board 21 is mounted inside the fixing frame 24, the bottom of the bionic board 21 can contact the roller 28. The operator can use the roller 28 to roll in the rolling groove 27 to easily push the bionic board 21 to slide along the fixing frame 24, accurately adjust the installation position, and improve the smoothness of the bionic board 21 during installation.

[0051] Compared with other installation methods, the human pushing resistance during the installation process is greatly reduced, effectively reducing the friction loss and operation difficulty during manual handling, especially in windy and wavey environments at sea, greatly improving the installation efficiency and safety.

[0052] Finally, the two ends of the fixing frame 24 are fixedly installed with a clamping strip 25, and the connecting part of the clamping strip 25 and the fixing frame 24 can be connected by bolts. At the same time, a protrusion 26 is fixedly installed on the clamping strip 25, and the protrusion 26 can be close to the side of the bionic board 21. When the bionic board 21 enters the interior of the fixing frame 24, the protrusion 26 contacts the side of the bionic board 21, so that the bionic board 21 can be limited inside the fixing frame 24, and the bolts on one group of clamping strips 25 are loosened, so that the clamping strip 25 and the protrusion 26 can be rotated on the fixing frame 24, so that one side of the fixing frame 24 can be exposed. At this time, the bionic board 21 can contact the external lifting equipment through the hook 23 for quick removal.

[0053] A method for constructing an assembled marine suction caisson comprises the following steps:

[0054] S1: In a factory environment, the assembled box body 11 is mass-produced according to the design specifications. During the casting process of the box body 11, the steel bars 12 are accurately embedded or welded at the key stress-bearing parts to enhance the structural strength. At this time, the side bars a13 and b14 are fixedly installed at both ends of the box body 11, and it is ensured that the groove on the side bar b14 is accurately matched with the side bar a13. At the same time, the opening 17 opened on the top of the box body 11 is used for fixing the lifting equipment, and the bottom thereof is processed with an outward-expanding bevel 19 to optimize the sinking performance. Then, a fixing frame 24 is fixedly installed on the outside of the box body 11, a rolling groove 27 is opened on the inner bottom thereof, and a roller 28 is installed in the rolling groove 27 to complete the foundation prefabrication of the caisson assembly 10.

[0055] S2: Independently prefabricate the bionic plate 21, open holes 22 of gradient size on its surface, and fix the hooks 23 at the ends. Fix the clamping strip 25 to the two ends of the fixing frame 24 with bolts, and then install the protrusions 26 on the clamping strip 25 to complete the assembly of the bionic component 20 and set it aside.

[0056] S3: Prepare construction equipment such as crane vessels, tugboats, air bags, vacuum pumps, etc., check the specifications and quality of materials such as lifting rigging and bolt connectors to ensure that they meet the design requirements, and formulate a detailed construction safety plan based on the construction sea environment.

[0057] S4: Use lifting equipment such as a crane ship to lift and fix the prefabricated caisson assembly 10 through the opening 17, and transport it smoothly to a designated location near the construction sea area. This method is suitable for long-distance and deep-water transportation, and can ensure the integrity and stability of the caisson assembly 10 during transportation.

[0058] S5: When the caisson assembly 10 is close to the coast or in a shallow area, an external air bag is placed at the bottom of the caisson assembly 10, and the caisson is lifted up after being inflated. A tugboat or shore traction equipment is used to pull the caisson assembly 10 through the air bag and roll it to the vicinity of the construction site with the help of the friction-reducing feature of the oblique opening 19 at the bottom of the box body 11, thereby reducing the difficulty and cost of transportation in shallow water areas.

[0059] S6: After the caisson assembly 10 is precisely positioned at the designed installation position, the airbag is controlled to be deflated or the lifting equipment is released to allow the caisson to fall steadily to the seabed. The vacuum pump is started to pump out the air inside the box body 11 to form a negative pressure. The suction principle is used in conjunction with the oblique opening 19 at the bottom of the box body 11 to guide the cutting into the foundation soil, so that the caisson assembly 10 can sink quickly and steadily to the predetermined depth. During this process, the verticality and sinking depth of the caisson are monitored in real time to ensure installation accuracy.

[0060] S7: After a single caisson assembly 10 is sunk into place, the grooves of the side bars a13 and b14 of the adjacent caissons are aligned with each other through mechanical assistance or manual fine-tuning to complete the splicing of the transverse caisson assembly 10, forming a stable planar array structure and enhancing the overall ability to resist horizontal loads.

[0061] S8: Use a small lifting device or a robotic arm to lift the bionic board 21 through the hook 23 at the end of the bionic board, and move it to the fixed frame 24 outside the box 11, so that the bottom of the bionic board 21 contacts the roller 28 in the fixed frame 24. With the help of the roller 28 rolling in the rolling groove 27, the bionic board 21 is pushed to slide along the fixed frame 24 to the installation position. When the bionic board 21 completely enters the fixed frame 24, the protrusion 26 on the card strip 25 is in close contact with the side of the bionic board 21, and the elastic deformation of the protrusion 26 is used to produce a limiting effect to prevent the bionic board 21 from moving.

[0062] S9: After checking that the installation position of the bionic board 21 is correct, tighten the bolts connecting the clamping strip 25 and the fixing frame 24 to ensure that the bionic component 20 is firmly installed. According to actual needs, the height of the bionic board 21 in the fixing frame 24 can be adjusted to make it in a suitable position in the sea water to play the best ecological function.

[0063] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
