[0002] To meet the ever-increasing demand for data and information, a large number of data centers need to be built. However, data centers require rapid heat dissipation during operation. To meet these cooling requirements and reduce costs, data centers are often located underwater, utilizing the properties of seawater for rapid heat dissipation. Furthermore, to ensure structural stability and facilitate routine maintenance, underwater corridors are necessary within the underwater structures.

It should be noted that the following embodiments can be referred to, learned from, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0024] The underwater corridor construction method and underwater construction equipment provided in this application are intended to solve at least one technical problem existing in the prior art.

[0025] This application provides an underwater construction device, such as... Figures 1-7 As shown, the underwater construction equipment includes: an equipment frame 1, an airbag forming module, and a pouring module; the equipment frame 1 is hollow, forming a pouring space for pouring underwater structures, the airbag forming module and the pouring module are set in the pouring space, and the underwater structure includes an underwater corridor; the airbag forming module includes a blow molding nozzle and a moving unit 2, the airbag forming module is used to form a pouring airbag in the pouring space through the blow molding nozzle, and the moving unit 2 is used to move the blow molding nozzle to provide space for placing the pouring airbag; the pouring module includes a pouring port 61 set on the outside of the blow molding nozzle, the pouring module is used to pour concrete 7 between the pouring airbag and the inner wall of the equipment frame 1 through the pouring port 61 to form an underwater corridor.

[0026] Optionally, the casting space can be a rectangular column structure or a cylindrical structure, and its specific shape can be determined according to actual needs.

[0027] Alternatively, underwater structures can also include underwater museums, underwater construction tunnels, underwater hotels, and other buildings with elongated, rectangular structures.

[0028] Optionally, during the underwater corridor pouring process, a slipform construction method can be adopted to gradually lower the already poured and pressure-resistant parts of the underwater corridor into the water. Specifically, the equipment frame 1 can be gradually moved during the pouring process to allow the underwater corridor to be removed.

[0029] Optionally, the blow molding nozzle may include a first blow molding nozzle 41 and a second blow molding nozzle 45, wherein the first blow molding nozzle 41 may surround the second blow molding nozzle 45, and the first blow molding nozzle 41 and the second blow molding nozzle 45 may be connected to an airbag or the shell of the airbag.

[0030] Optionally, a polymer slurry can be blown out from the first blow molding nozzle 41 and the second blow molding nozzle 45. The polymer slurry reacts with air or specific additives to form a material to be blow molded. The material to be blow molded can be in a semi-solid state or in a state that can expand after air is blown in. Air can then be blown into the material to be blow molded using the first blow molding nozzle 41 and the second blow molding nozzle 45 to form a double-layer airbag structure.

[0031] Optionally, the main material of the polymer slurry can be polyvinyl acetate and other materials capable of forming air pockets by blowing and enabling the surface of the formed air pockets to solidify rapidly within the casting space. Additives can be materials that increase the strength of the air pockets and reduce the solidification time of the material to be blown.

[0032] Optionally, the polymer slurry used in the first blow molding nozzle 41 and the second blow molding nozzle 45 can be the same or different. The casting airbag can be formed by multiple gas-filled airbag structures, and the impact of leakage from a single airbag during the concrete casting process is reduced by the construction of the multi-airbag structure.

[0033] In one embodiment, the underwater structure is an underwater corridor. The first blow molding nozzle 41 is positioned relative to the second blow molding nozzle 45 near the side wall of the pouring space (i.e., the inner wall of the equipment frame 1), forming a first airbag 43 that directly contacts the inner wall of the underwater structure. The second blow molding nozzle 45 is located in the middle of the pouring space relative to the first blow molding nozzle 41, forming a second airbag 44. The first airbag 43 surrounds the second airbag 44, thus supporting the first airbag 43. During the concrete 7 pouring process, the equipment frame 1 acts as the outer mold, while the first airbag 43 and second airbag 44 act as the inner mold, with the second airbag 44 providing overall support. The shape of the concrete 7 can be precisely controlled by finely adjusting the air pressure injected into the first airbag 43 through the first blow molding nozzle 41. For example, by injecting appropriate air into the first airbag 43 and second airbag 44, an inner mold airbag of the designed shape can be formed. However, in order to make the underwater corridor more compact, the grouting pressure will be appropriately increased at the end of the concrete grouting process. The concrete grout has a large pressure, which will squeeze the air bladder. The air inside the air bladder will deform to a certain extent, which will affect the final outline and the compaction effect due to the lack of good restraint.

[0034] Alternatively, the size of the airbag and the air pressure inside the airbag can be determined based on information such as the weight and thickness of the poured concrete to make the resulting airbag more suitable for the pouring requirements of underwater structures.

[0035] Optionally, to reduce the impact of seawater on underwater structures and protect them, the underwater construction equipment also includes a waterproof membrane forming module equipped with polymer spray nozzles 11. The polymer spray nozzles 11 are distributed on the inner wall of the equipment frame 1, and the waterproof membrane forming module is used to form a waterproof membrane on the outer wall of the underwater corridor through the polymer spray nozzles 11.

[0036] Optionally, during the process of removing the underwater corridor from the equipment frame 1, the waterproof membrane material corresponding to the waterproof membrane can be sprayed onto the side of the concrete 7 near the inner wall of the equipment frame 1, thereby forming a polymer membrane on the surface of the underwater building. This polymer membrane can be used to improve the anti-seepage and anti-segregation effect of the underwater building and protect the underwater building.

[0037] Optionally, the polymer membrane can be a polyolefin membrane (such as a polypropylene hollow fiber membrane or a polyethylene composite membrane), a polyamide membrane (an aromatic polyamide (PA) composite membrane), a fluorinated polymer membrane, or other materials that can adhere to the concrete surface and form a film quickly after spraying.

[0038] In one embodiment, the polymer spray nozzle 11 is located at the contact point between the outer mold (i.e., equipment frame 1) and the underwater corridor, specifically at the underwater corridor exiting end of equipment frame 1. As the underwater corridor is continuously "squeezed out" (i.e., the underwater corridor moves into the water), a waterproof membrane is formed on the outer surface of the underwater corridor through the polymer spray nozzle 11, providing good anti-seepage and anti-segregation effects when the underwater corridor comes into contact with seawater. Simultaneously, it serves as a structural protective layer for the concrete corridor during its service life, solving the problem of difficult construction of the outer surface protective layer after the completion of underwater cast-in-place concrete structure 7.

[0039] Optionally, the underwater construction equipment also includes a storage bin 3, with the initial ends of the storage bin 3 and the pouring airbag located at opposite ends of the pouring space. The storage bin 3 includes multiple sub-compartments, where the raw materials, compressed air, and concrete 7 corresponding to the pouring airbag and the waterproof membrane are stored. The raw materials, compressed air, and concrete 7 are stored in different sub-compartments. The sub-compartments connected to the polymer spray nozzle 11 and the blow molding nozzle can be different, and they use different polymer liquids.

[0040] Optionally, the moving unit 2 includes a hydraulic cylinder 22 and a hydraulic rod 21. One end of the hydraulic rod 21 is connected to the drive end of the hydraulic cylinder 22, and the other end is connected to the blow molding nozzle. When forming the casting airbag, the power of the hydraulic cylinder 22 can be used to drive the blow molding nozzle to move, so that the casting airbag gradually increases in size within the casting space.

[0041] Optionally, the underwater construction equipment may also include a fixed plate 42, on which the blow molding nozzle can be fixed, and the pouring port 61 can be located on the outside of the fixed plate 42 and close to the inner wall of the equipment frame 1. When the hydraulic cylinder 22 moves the blow molding nozzle through the hydraulic rod 21, the pouring port 61 also moves accordingly, thereby realizing continuous pouring of the underwater structure.

[0042] Optionally, the underwater construction equipment may include a separating membrane (such as a plastic membrane closed at one end) or an auxiliary support (such as a strip-shaped foldable device with multiple support structures). The separating membrane or auxiliary support may be foldable or compressible, and one end may be fixedly connected to the side of the fixing plate 42 away from the hydraulic rod 21. This end may be located in the annular region between the first blow molding nozzle 41 and the second blow molding nozzle 45, or the separating membrane or auxiliary support may be provided in the annular region and on the outer side of the annulus formed by the first blow molding nozzle 41. The separating membrane separates the first airbag 43 and the second airbag 44, or the auxiliary support supports the second airbag 44 and defines the size of the first airbag 43.

[0043] Optionally, when setting the separator membrane, it can be inflated to form an air bladder, and the air bladder can be reinforced by spraying a rapidly solidifying material (such as a sealant that can cure quickly, or a foaming adhesive with high hardness after curing) using the first blow molding nozzle 41 and the second blow molding nozzle 45. When setting the auxiliary support, the auxiliary support can also be filled with the material sprayed from the first blow molding nozzle 41 and the second blow molding nozzle 45 and surrounded by its outer side to obtain a structure that can support the concrete 7 when it is poured.

[0044] Optionally, the blow molding nozzle is connected to sub-compartments storing raw materials (polymer slurry) and compressed air, respectively. The blow molding nozzle and / or storage silo 3 are equipped with controllers for controlling the sub-compartments connected to the blow molding nozzle. These controllers control the sub-compartments connected to the blow molding nozzle, thereby controlling the blow molding nozzle to blow out the compressed air or polymer slurry corresponding to the material to be blow molded. The controller can be a control valve or other devices capable of controlling the connection between the blow molding nozzle and the sub-compartments.

[0045] Optionally, the sub-compartment storing concrete 7 is connected to the pouring port 61, and the polymer spraying port 11 is connected to the sub-compartment storing the material corresponding to the waterproof membrane. The equipment frame 1 may be provided with a transmission channel for transporting the material corresponding to the waterproof membrane, through which the material is transported to the polymer spraying port 11.

[0046] Optionally, the hydraulic rod 21 may have built-in multiple pipes, such as a compressed air pipe and a polymer slurry pipe. The compressed air pipe transmits compressed air to the blow molding nozzle, and the polymer slurry pipe transmits polymer slurry to the blow molding nozzle. This piping may also include a control signal transmission pipe for transmitting control signals used to open or close the blow molding nozzle.

[0047] Optionally, the pouring port 61 is connected to a sub-compartment for storing concrete 7 via a concrete 7 transmission pipe, and the storage compartment 3 may be equipped with a concrete 7 pump for transmitting concrete 7 to the pouring.

[0048] Optionally, the underwater construction equipment may also include at least two walking modules. Each walking module includes a frame support beam 53, a rotating shaft 54, and a walking mechanism 5. The frame support beam 53 is fixed to the bottom of the equipment frame 1. One end of the rotating shaft 54 ​​is fixedly connected to the frame support beam 53, and the other end is connected to the walking mechanism 5.

[0049] Optionally, the frame support beam 53 can be multiple, with multiple support beams fixed to the bottom of the equipment frame 1, and the rotating shaft 54 ​​can be fixed to the frame support beam 53. The traveling mechanism 5 can drive the rotating shaft 54 ​​to rotate or rotate relative to the rotating shaft 54.

[0050] Optionally, the traveling mechanism 5 includes tracks 52 and a drive unit connected to the tracks 52 for rotating the tracks 52. The tracks 52 and the drive unit then move the equipment frame 1 underwater or on land.

[0051] Optionally, the walking mechanism 5 also includes a telescopic unit with a telescopic rod 51. The telescopic end of the telescopic rod 51 is connected to the rotating shaft 54. The telescopic unit is used to drive the equipment frame 1 to rise and fall.

[0052] In one embodiment, multiple walking mechanisms 5 can be provided, each connected to a rotating shaft 54. Each walking mechanism 5 is equipped with tracks 52 and telescopic rods 51. The walking mechanism 5 rotates around the rotating shaft 54 ​​of the frame mounted on the supporting beam, giving the poured concrete 7 connecting corridor a certain slope to adapt to different slopes during construction. The extension and retraction of the telescopic rods 51 can adjust the height of the equipment frame 1 to adapt to different seabed walking bases, ensuring that underwater connecting corridors of the same elevation can be poured on seabed bases at different elevations.

[0053] Optionally, to facilitate the underwater corridor's separation from the equipment frame 1, the equipment frame 1 includes an end cap. The end cap is fastened to one end of the equipment frame 1, with its inner side contacting the pouring space, and the end cap and the initial end of the pouring airbag located at the same end of the pouring space. The initial end of the underwater corridor can be immersed in water for drying. The end cap can be opened or removed, and the initial end can be moved out of the pouring space by the pushing of the internal hydraulic cylinder 22 and the movement of the traveling mechanism 5. During the subsequent pouring process, the other parts of the underwater corridor are gradually moved out.

[0054] The underwater construction equipment described in this application will be further explained below using the construction process of the underwater connecting corridor as an example.

[0055] In one embodiment, such as Figures 3-7 As shown, after the equipment is submerged in water, it can be moved to the construction location using the walking mechanism 5. At this time, the water around the equipment can be cleared, or it can remain submerged. Inside the equipment frame 1, there is a closed, waterless pouring space. One end of the equipment frame 1 is equipped with an end cap (on the one hand, the end cap seals the pouring space to prevent seawater from entering the pouring space; on the other hand, it provides horizontal support reaction force to the pouring airbag). The hydraulic rod 21 is pushed to the position of the end cap. According to the set parameters (these parameters can be the structural characteristics of the concrete 7 used in the underwater corridor, such as the geometric dimensions of the structure formed by the concrete 7, the material density of the concrete 7, etc.), the airbag parameters such as the size, thickness, and air pressure of the bubbles to be produced are determined. Based on the airbag parameters, the amount of polymer slurry to be extruded by the first blow molding nozzle 41 and the second blow molding nozzle 45 each time to form the material to be blown and the amount of air to be injected into the pouring airbag during blowing are determined.

[0056] These parameters can be determined by conducting typical tests, in which a material to be blown is formed by extruding a polymer slurry through a first blow molding nozzle 41 and a second blow molding nozzle 45, and then compressed air is injected into it to form a first airbag 43 and a second airbag 44.

[0057] After the first airbag 43 and the second airbag 44 are formed, air continues to be injected, causing the first airbag 43 and the second airbag 44 to expand axially to reach the standard size (a thickness detection radar can be installed on the equipment frame 1, which penetrates obstacles through electromagnetic waves. When the electromagnetic waves encounter the concrete 7 and the airbags, different images are presented. Information such as the thickness of the concrete 7 and the size of the poured airbags can be obtained from the images to detect whether the standard size has been reached. Alternatively, the detection information of the concrete 7 can be obtained after the concrete 7 is poured. When it is detected that there are no voids inside the concrete 7 and the thickness of the plate is within ±1cm of the design thickness, it is considered that the size of the structure formed by the concrete 7 has reached the standard size). At this time, the hydraulic cylinder 22 drives the hydraulic rod 21 to retract accordingly (the retraction distance, the start time of retraction, the retraction speed and other parameters can be determined according to the setting time of the concrete 7, the strength development time and other parameters of the concrete 7. If the setting time of the concrete 7 is short and the strength development is fast, the retraction distance can be set larger. Typical tests can be carried out on land to determine this).

[0058] Since the amount of polymer slurry extruded in a single batch is limited, multiple rows of airbags can be formed by repeating the steps of airbag formation and expansion, thereby obtaining casting airbags of sufficient size in the axial direction. Adjacent rows of airbags can be internally connected in the axial direction. At the end of construction, a row of airbags can be pressurized as needed to resist the grouting load of concrete 7.

[0059] After the length and strength of the airbag meet the requirements for pouring concrete 7, concrete 7 can be poured using the pouring port 61, which can surround the airbag. Furthermore, to achieve continuous pouring, the underwater corridor can be poured using a slipform construction process. During pouring, the equipment frame 1 is moved simultaneously according to the underwater corridor's route, and the portion of the corridor that has been poured and is ready to be placed in the water is lowered into the water during this movement.

[0060] The underwater construction equipment of this application includes an equipment frame, an airbag forming module, and a casting module. The equipment frame is hollow, forming a casting space for casting underwater structures. The airbag forming module and the casting module are disposed within the casting space. The underwater structure includes an underwater corridor. The airbag forming module includes a blow molding nozzle and a moving unit. The airbag forming module is used to form a casting airbag within the casting space through the blow molding nozzle. The moving unit is used to move the blow molding nozzle to provide space for placing the casting airbag. The casting module includes a casting port disposed on the outside of the blow molding nozzle. The casting module is used to pour concrete through the casting port between the casting airbag and the inner wall of the equipment frame to form an underwater corridor. This embodiment of the application enables the underwater construction of underwater corridors using underwater construction equipment, effectively avoiding the need for onshore casting and transportation, significantly shortening the construction cycle, effectively reducing construction costs, reducing the impact of weather, improving construction efficiency, and reducing safety and quality risks.

[0061] Based on the same inventive concept, this application also proposes an underwater corridor construction method, which is used with the underwater construction equipment described in the above embodiments, such as... Figure 8 As shown, the method includes: S101: Move the underwater construction equipment to the location where construction will take place.

[0062] Alternatively, the underwater corridor construction equipment can be transported to the construction site by ship, or it can be moved to the construction site using the traveling mechanism of the underwater corridor construction equipment.

[0063] S102: The airbag forming module is used to form a casting airbag in the casting space, and the moving unit gradually drives the airbag forming module to move.

[0064] Optionally, the airbag forming module is moved step by step to provide forming space for the casting airbag, so that the size of the casting airbag can reach the size required for casting concrete.

[0065] S103: Concrete is poured between the casting airbag and the inner wall of the equipment frame using casting modules to form an underwater corridor.

[0066] Optionally, the concrete pouring process corresponds to the formation process of the airbag. Furthermore, during the pouring process, the sections of the underwater corridor that have already been poured and are ready to be submerged can be gradually placed into the water. A waterproof membrane can also be formed on the surface of these sections to prevent the concrete from segregating and disintegrating upon contact with water.
