Description

Technical Field

[0001] This application relates to the field of flow generation device technology, and in particular to an embedded flow guiding structure and construction method for a deep-water multi-layer flow generation system. Background Technology

[0002] Deep-water multi-layer flow generation systems are experimental facilities used to simulate uniform flow, profile flow, and other flow field environments in deep water. They typically consist of multiple horizontally arranged baffles arranged sequentially along the height of a pool to create multiple interlayer channels for water supply and return. Each interlayer channel is equipped with pump units, outlets, and return chambers, allowing water from different heights to enter the main experimental area, thus meeting the experimental needs of deep-water oil and gas platforms, underwater intelligent equipment, and deep-sea aquaculture equipment.

[0003] In the above system, the velocity, direction, and boundary conditions of the water flow in different layers before entering the main test area will affect the uniformity, directional stability, and repeatability of the final flow field. To improve the flow pattern before the water enters the main test area, engineering practices typically involve installing components such as guide vanes in the interlayer channels to guide and divert the water flow.

[0004] Existing flow guiding components are mostly monolithic structures. After the layer plates are constructed, they are fixed between the partitions by welding or other methods. The installation process is cumbersome, and the irregular welds formed at the welding positions can affect the flow guiding quality. Summary of the Invention

[0028] Furthermore, the upper and lower embedding grooves are provided with pre-embedded metal parts;

[0029] The embedded metal part is at least partially embedded in the upper cast-in-place body or the lower cast-in-place body.

[0030] Furthermore, the interlayer structure includes a plurality of the flow guides;

[0031] The interlayer structure also includes a fixing plate;

[0032] The fixing plate extends along the arrangement direction of the plurality of flow guides and is connected to the plurality of flow guides respectively, thereby restricting the relative position of the plurality of flow guides from changing.

[0033] Furthermore, the interlayer structure also includes multiple fixing plates;

[0034] The plurality of fixing plates are spaced apart along the vertical direction.

[0035] A second aspect of this application provides a construction method for an embedded flow guiding structure used to form a deep-water multi-layer flow generation system, comprising:

[0036] When the upper and lower plates are formed, an upper mounting groove is reserved on the side of the upper plate facing the lower plate, and a mounting groove is reserved on the side of the lower plate facing the upper plate.

[0037] The flow guide is disposed between the upper plate and the lower plate, such that the upper end of the flow guide extends into the upper mounting groove and the lower end of the flow guide extends into the lower mounting groove.

[0039] Cement-based casting material is poured into the upper and lower embedding grooves, and the cement-based casting material solidifies to form the upper and lower embedded solids.

[0040] As can be seen from the above technical solutions, this application provides an embedded flow guiding structure and construction method for a deep-water multi-layer flow generation system; wherein, the embedded flow guiding structure includes: multiple interlayer structures arranged along the height direction; the interlayer structures include an upper layer plate and a lower layer plate arranged at intervals along the height direction, and a plurality of flow guiding components disposed between the upper layer plate and the lower layer plate; an interlayer channel is formed between the upper layer plate and the lower layer plate; an upper fixing groove is provided on the side of the upper layer plate facing the lower layer plate; a lower fixing groove is provided on the side of the lower layer plate facing the upper layer plate, which is aligned with the upper fixing groove; the upper end of the flow guiding component extends into the upper fixing groove; the lower end of the flow guiding component extends into the lower fixing groove; the upper fixing groove is used for the upper end...

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0064] Please see Figure 1 and Figure 2 The first aspect of this application provides an embedded flow guiding structure for a deep-water multi-layer flow generation system, which includes multiple interlayer structures arranged sequentially along the height direction. Different interlayer structures form water flow output areas at different heights, enabling water flow from each layer to enter the main test area according to a set flow velocity and direction. The multiple interlayer structures, together with the water tank, constitute a deep-water multi-layer flow generation system.

[0065] In this embodiment, the interlayer structure includes an upper plate 1 and a lower plate 2 spaced apart along the height direction, forming an interlayer channel 3 between the upper plate 1 and the lower plate 2. The upper plate 1 and the lower plate 2 extend horizontally and together define the upper and lower boundaries of the interlayer channel 3. Multiple interlayer structures are arranged along the height direction, thereby forming multiple interlayer channels 3 at different heights in the deep-water multilayer flow generation system.

[0066] In this embodiment, the upper layer 1 and the lower layer 2 are formed by concrete casting. In other embodiments, the upper layer 1 and the lower layer 2 may also be metal layers, composite layers, or other structures capable of forming interlayer channels 3. Adjacent interlayer structures may also share a layer located between them, so that the layer simultaneously constitutes the lower boundary of one interlayer channel 3 and the upper boundary of the other interlayer channel 3.

[0067] Several flow guides 4 are provided between the upper plate 1 and the lower plate 2. The flow guides 4 can be configured as flat plates or plate-like components with flow-guiding curved surfaces. One or more flow guides 4 can be configured in the interlayer structure as needed. When multiple flow guides 4 are configured, each flow guide 4 can be arranged in the interlayer channel 3 according to a predetermined flow direction. The specific number, spacing, and extension direction of the flow guide surfaces of the flow guides 4 can be determined according to the target flow field, so that the water flowing through the interlayer channel 3 is guided and diverted before entering the main test area.

[0068] The upper plate 1 has an upper mounting groove 11 on the side facing the lower plate 2, and the lower plate 2 has a lower mounting groove 21 on the side facing the upper plate 1. The upper mounting groove 11 and the lower mounting groove 21 open towards the interlayer channel 3 and correspond to each other at the installation position of the flow guide 4. "Corresponding to each other" means that the upper mounting groove 11 and the lower mounting groove 21 are aligned and can respectively receive the upper end 41 and the lower end 42 of the same flow guide 4, so that the installed flow guide 4 spans between the upper plate 1 and the lower plate 2.

[0069] The upper end 41 of the guide member 4 extends into the upper fixing groove 11, and the lower end 42 of the guide member 4 extends into the lower fixing groove 21. A space is left between the upper end 41 and at least part of the groove wall of the upper fixing groove 11 for cement-based casting material to enter, and a space is also left between the lower end 42 and at least part of the groove wall of the lower fixing groove 21 for cement-based casting material to enter.

[0070] An upper embedded body 5 is provided in the upper embedded groove 11. The upper embedded body 5 is formed by pouring cement-based casting material between the upper end 41 and the groove wall of the upper embedded groove 11 and solidifying it, thereby surrounding or abutting at least a portion of the upper end 41 and fixing the upper end 41 in the upper embedded groove 11.

[0071] A lower embedded embedment 6 is provided in the lower embedded groove 21. The lower embedded embedment 6 is formed by pouring cement-based casting material between the lower end 42 and the groove wall of the lower embedded groove 21 and solidifying it, thereby surrounding or abutting at least a portion of the lower end 42 and fixing the lower end 42 in the lower embedded groove 21.

[0072] The cement-based casting material can be fine aggregate concrete, cement mortar, cement-based grout, or other materials that, after curing, can embed the guide member 4 into the corresponding embedding groove. After the cement-based casting material cures, the upper casting embedding body 5 and the lower casting embedding body 6 are respectively bonded to the groove wall of the corresponding embedding groove, forming a stable load transfer structure between the guide member 4 and the upper plate 1 and the lower plate 2.

[0073] In practical applications, the embedded flow guiding structure provided in this embodiment can be constructed through the following process:

[0074] During construction, the quantity and installation position of the flow guide 4 are first determined according to the flow field requirements of each layer, and the positions of the upper and lower embedded grooves 11 and 21 are determined accordingly. Then, when forming the upper plate 1 and lower plate 2, groove forming components are set in the corresponding templates, so that the upper plate 1 facing the interlayer channel 3 forms the upper embedded groove 11, and the lower plate 2 facing the interlayer channel 3 forms the lower embedded groove 21. The upper and lower embedded grooves 11 and 21 correspond to each other in the vertical direction. After the upper plate 1 and lower plate 2 reach the required installation strength, the aforementioned groove forming components are removed, thus forming the upper and lower embedded grooves 11 and 21. Afterwards, the grooves can be cleaned appropriately. Next, the guide component 4 is installed. Specifically, the guide component 4 is first inserted into the interlayer channel 3 in an inclined and horizontal position. Then, the upper end 41 is inserted into the upper mounting groove 11. The guide component 4 is then rotated so that the lower end 42 is aligned with the lower mounting groove 21. Subsequently, the height and orientation of the guide component 4 are adjusted so that the lower end 42 enters the lower mounting groove 21. The upper mounting groove 11 and the lower mounting groove 21 provide assembly allowance for the guide component 4.

[0075] After the guide component 4 is in place, the lower embedding groove 21 can be poured first for temporary positioning, maintaining the installation position, flow direction, and vertical posture of the guide component 4, and preventing the guide component 4 from moving during the pouring process. The remaining guide components 4 within the same interlayer channel 3 are then installed in the same manner. Specifically, during pouring, removable molded support components 9 can be installed at the openings of the upper embedding groove 11 and the lower embedding groove 21. The molded support components 9 seal the openings of the corresponding embedding grooves, ensuring that their end faces are on the same plane as the surfaces of the upper plate 1 and the lower plate 2 facing the interlayer channel 3. The molded support components, together with the groove walls of the embedding grooves and the corresponding ends of the guide components 4, define the pouring space.

[0076] Subsequently, cement-based casting material is poured into the space between the upper end 41 and the wall of the upper embedding groove 11, and into the space between the lower end 42 and the wall of the lower embedding groove 21. For the upper embedding groove 11, cement-based casting material can be injected through the pre-reserved injection channel 12 in the groove; for the lower embedding groove 21, casting can be performed through the groove opening.

[0077] After the cement-based casting material cures, an upper casting embedding body 5 is formed in the upper embedding groove 11, and a lower casting embedding body 6 is formed in the lower embedding groove 21. Because the casting material is constrained by the forming surface of the molded support during the curing process, the exposed surface of the upper casting embedding body 5 at the groove opening of the upper embedding groove 11 is flush with the surface of the upper layer plate 1 facing the interlayer channel 3, and the exposed surface of the lower casting embedding body 6 at the groove opening of the lower embedding groove 21 is flush with the surface of the lower layer plate 2 facing the interlayer channel 3. If necessary, the end face at the groove opening can be trimmed to eliminate local high points.

[0078] In this embodiment, the molded support component 9 can be composed of two or more detachable and splicable plates. The opposing sides of the plates are respectively provided with clearance notches that are adapted to the outer contour of the guide component 4. After multiple plates are spliced ​​together, they jointly surround the guide component 4 and seal the groove opening to form a casting surface that fits tightly with the guide component 4.

[0079] It should be noted that in this embodiment, there are no special requirements for the uniformity of the upper cast-in-place solid 5 and the lower cast-in-place solid 6. Specifically, the solid should be able to fix the guide 4, and the end face of the solid should be flush.

[0080] Specifically, in existing technologies, the flow guide 4 typically needs to be directly installed between the upper plate 1 and the lower plate 2. To ensure that the flow guide 4 can guide the flow across the entire height range of the interlayer channel 3, its height is generally adapted to the net height of the interlayer channel 3. Therefore, if the flow guide 4 is sent into the interlayer channel 3 in a horizontal or inclined posture, the end of the flow guide 4 will interfere with the upper plate 1 or the lower plate 2 during the process of rotating from the inclined posture to the vertical installation posture. Especially when the height of the interlayer channel 3 is small, the size of the flow guide 4 is large, or the interlayer channel 3 is a tortuous channel in the horizontal direction, the flow guide 4 often does not have the space required to complete the rotation and posture adjustment after entering the interlayer channel 3. Therefore, existing flow guides usually need to be pre-positioned in a near-vertical posture and sent into the interlayer channel as a whole along the predetermined installation direction, which severely restricts the transport posture, entry path, and hoisting space of the flow guide, making the installation operation difficult and time-consuming, and affecting the installation accuracy due to collisions or positioning errors.

[0081] This solution, by setting up mutually aligned upper and lower fixing grooves 11 and 21, allows the two fixing grooves to not only serve as a fixing structure after the guide component 4 is installed, but also as a margin for the guide component 4 to rotate and adjust its attitude during the installation process. This breaks through the limitation of the existing technology that the guide component 4 can only be sent into the inter-layer channel as a whole in the final vertical posture, reduces the requirements of the guide component 4 for construction operation space, and shortens the installation and positioning time of the guide component 4.

[0082] Furthermore, without the installation of a retaining groove, the upper and lower ends of the guide member 4 can only be fixed to the layer plate. To withstand the impact load generated by the water flow on the guide member 4, exposed fixing structures such as welds, angle steel, and connecting seats need to be installed at the root of the guide member 4, or a cast-in-place root protruding into the interlayer channel 3 can be directly cast around the root of the guide member 4. The above-mentioned fixing structures not only occupy the space within the interlayer channel 3, but also affect the water flow quality and the stability of the test results.

[0083] This solution, through the upper embedded groove 11 and the lower embedded groove 21, enables the exposed surfaces of the upper cast embedded solid 5 and the lower cast embedded solid 6 to be flush with the surfaces of the corresponding layer plates facing the interlayer channel 3, thereby completing the fixation of the flow guide 4 while reducing the additional disturbance to the water flow in the connection area. Thus, it can meet the requirements of stable layered output of the deep-water multi-layer flow generation system while taking into account the convenient installation and positioning of the flow guide 4 and the long-term structural stability.

[0084] In some embodiments, please refer to Figures 1 to 6 In this embodiment, the flow guide 4 can adopt a split structure. Specifically, the flow guide 4 includes multiple independently formed flow guide units 43, which are arranged sequentially along the height direction and aligned with each other. Adjacent flow guide units 43 are connected by a splicing structure 44, thereby splicing multiple flow guide units 43 in the interlayer channel 3 to form a flow guide 4 capable of guiding and diverting water flow.

[0085] In this embodiment, the flow guiding unit 43 can be a plate-shaped structure; different flow guiding units 43 can have the same height, or they can be set differently according to the installation position, the space they enter, and the force conditions of the connection position.

[0086] In this embodiment, the splicing structure 44 is disposed between the two splicing ends to limit the relative displacement of adjacent flow guiding units 43 along the thickness or width direction of the flow guiding member 4, and to enable adjacent flow guiding units 43 to jointly bear the load generated by the water flow. The splicing structure 44 can be integrally formed with the flow guiding unit 43.

[0087] In this embodiment, after multiple flow guiding units 43 are assembled, the uppermost flow guiding unit 43 forms the upper end 41 of the flow guiding component 4, and the lowermost flow guiding unit 43 forms the lower end 42 of the flow guiding component 4. During assembly, the lowermost flow guiding unit 43 can also be placed in the lower fixing groove 21 first, and then the other flow guiding units 43 can be connected in sequence from bottom to top.

[0088] In this embodiment, the splicing structure 44 may include one or more of the following: mortise and tenon structure, pin structure, and locking structure that can cooperate with each other; wherein, the splicing structure 44 may be made of engineering plastics or other materials that are suitable for processing and use in water tanks.

[0089] In this embodiment, the flow guide 4 is divided into multiple smaller flow guide units 43, so that each flow guide unit 43 can enter the installation position through the interlayer channel 3 and be reassembled along the height direction inside the interlayer channel 3 to form a complete flow guide 4. This further reduces the requirements of the flow guide 4 for the conveying space, and makes the flow guide 4 adaptable to situations where there is a narrow space and a tortuous flow channel inside the interlayer channel 3.

[0090] In one embodiment, the splicing structure 44 adopts a mortise and tenon structure with horizontal insertion, allowing adjacent flow guiding units 43 to be connected or separated by horizontal movement, and fixed by horizontally inserted components. Thus, the flow guiding unit 43 located in the middle of the flow guiding member 4 can be individually pulled out or inserted from the side, while the flow guiding units 43 located on the uppermost and lowermost sides remain embedded in the upper fixing groove 11 and the lower fixing groove 21, respectively.

[0091] When the central flow guiding unit 43 is deformed or damaged, it is only necessary to disconnect the corresponding tenon and mortise connection and replace the flow guiding unit 43, without having to completely remove the flow guiding part 4, or damage the upper and lower cast-in-place solid 5 and the lower cast-in-place solid 6. This reduces the need for dismantling and re-pouring operations, avoids secondary damage to the slab and the embedded foundation, shortens maintenance time and reduces maintenance costs.

[0092] In one implementation, a seam 45 is formed between the splicing ends of adjacent flow guiding units 43. A seal can be installed within the seam 45 before the flow guiding units 43 are spliced. The seal can be made of water-resistant, corrosion-resistant EPDM rubber, silicone rubber, or polyurethane sealing strips with low water absorption. The above-mentioned seal can withstand long-term immersion, water pressure, and periodic impact in deep water flow environments, preventing water flow from passing through the seam 45 to form local jets and reducing local eddies and turbulence.

[0093] In one embodiment, both the upper fixing groove 11 and the lower fixing groove 21 are long grooves that extend continuously along the arrangement direction of the multiple flow guides 4. The multiple flow guides 4 are arranged at intervals along the extension direction of the long grooves, with the upper end 41 of each flow guide 4 extending into the same upper fixing groove 11 and the lower end 42 extending into the same lower fixing groove 21. After adjusting the spacing and flow direction, cement-based casting material is poured into the long grooves to simultaneously fix the multiple flow guides 4. The use of continuous long grooves in this embodiment simplifies the groove forming process.

[0094] In another embodiment, the upper plate 1 has multiple spaced-apart upper mounting grooves 11, and the lower plate 2 has corresponding multiple lower mounting grooves 21. Each set of aligned upper mounting grooves 11 and lower mounting grooves 21 corresponds to a flow guide 4, with its upper end 41 and lower end 42 extending into the corresponding mounting groove and fixed by an independent cast-in-place solid. By configuring each flow guide 4 with a corresponding mounting groove, this embodiment can directly define the installation position, spacing, and flow direction of the flow guide 4, reducing the offset of the flow guide 4 along the plate surface. Simultaneously, each mounting position can be constructed and maintained separately, and damage to a single flow guide 4 does not affect adjacent flow guides 4 and their mounting structures.

[0095] In one embodiment, embedded metal parts 7 are provided in the upper embedding groove 11 and the lower embedding groove 21. The embedded metal parts 7 can be pre-embedded during the casting of the upper plate 1 and the lower plate 2, with one part anchored inside the corresponding plate and the other part extending into the upper embedding groove 11 or the lower embedding groove 21, and then embedded in the upper casting embedding body 5 or the lower casting embedding body 6 during subsequent casting. The embedded metal parts 7 can be steel bars, anchor rods, steel plates, studs, or a combination of the above structures.

[0096] The embedded metal part 7 can form a mechanical anchor between the layer plate and the cast-in-place solid, increasing the bonding strength between the two, so that the water flow impact and vibration load borne by the guide part 4 can be more reliably transferred to the layer plate, and improving the long-term stability of the guide part 4 in deep water environment.

[0097] In one embodiment, a plurality of flow guides 4 are arranged at intervals along the width direction of the interlayer channel 3, and a fixing plate 8 extends along the arrangement direction of the plurality of flow guides 4 and is connected to each flow guide 4 in sequence. The fixing plate 8 can be connected to the flow guides 4 by means of slots, bolts, snap-fits or welding to maintain the spacing and flow guiding angle between each flow guide 4.

[0098] The fixing plate 8 connects multiple independent guide members 4 to form a whole that can support each other, thereby limiting the relative displacement, rotation or deformation of the guide members 4 under the impact and vibration of water flow, and dispersing the local load on a single guide member 4 to adjacent guide members 4, thereby improving the structural stability and consistency of the guiding direction of the whole group of guide members.

[0099] In this embodiment, the fixing plate 8 can be configured as a plate structure with a low thickness, such as using a metal plate with a thickness of 1-2mm, and after installation, it is parallel to the horizontal plane to reduce the interference of the fixing plate 8 on the water flow.

[0100] In this embodiment, the fixing plate 8 can be formed by splicing multiple fixing plate units. Each fixing plate unit is connected to a portion of the flow guide 4, and after splicing, they together form a fixing plate 8 that is adapted to the shape of the flow guide 4.

[0101] In this embodiment, there can be multiple fixing plates 8, which are arranged sequentially along the arrangement direction of multiple flow guides 4 to reduce the installation difficulty of the fixing plates 8 and the flow guides 4.

[0102] For example, when the interlayer structure has four flow guides 4, two fixing plates 8 can be set along the arrangement direction of the flow guides 4; each fixing plate 8 is formed by splicing two fixing plate units, and each fixing plate unit is connected to two flow guides 4. The two fixing plates 8 are arranged sequentially along the thickness direction of the flow guides 4.

[0103] In practical applications, the fixing plate 8 and the flow guide 4 can be pre-fixed outside the interlayer channel 3 before being sent into the interlayer channel 3 together, thus avoiding the problem of difficult assembly inside the interlayer channel 3. Specifically, when the flow guide 4 includes multiple flow guide units 43, the fixing plate 8 is pre-fixed with the corresponding flow guide unit 43 to form an assembly, and then the assembly and the individual flow guide unit 43 are sent into the interlayer channel 3. For example, a fixing plate 8 can be configured to connect two flow guide units 43, and the assembly of the assembly with other flow guide units 43 can be completed inside the interlayer channel 3.

[0104] It should be noted that, for existing flow guides, since they need to be kept in a near-vertical position beforehand, configuring a fixing plate for the existing flow guides would further increase the installation efficiency and difficulty. In this embodiment, by configuring the upper fixing groove 11, the lower fixing groove 21 and multiple flow guide units 43, the fixing plate 8 and the flow guide 4 can be installed more conveniently inside the interlayer channel 3.

[0105] As one implementation method, the interlayer channel 3 has groove walls on both sides in the width direction; the end of the fixing plate 8 is inserted into the groove wall to improve the stability of the fixing plate 8 after installation.

[0106] In one embodiment, multiple fixing plates 8 can be provided along the vertical direction of the flow guide 4. For example, two fixing plates 8 can be provided along the vertical direction of the flow guide 4. The two fixing plates 8 can be respectively set at two third points from the flow guide 4 along the vertical direction, so as to constrain multiple flow guides 4 from different heights at the same time, shorten the length of the unsupported part of the flow guide 4, reduce the risk of bending, twisting or relative displacement under the impact of deep water flow, and improve the stability of the entire group of flow guides 4.

[0107] A second aspect of this application provides a construction method for forming an embedded flow guiding structure in a deep-water multi-layer flow generation system, the construction method comprising the following steps:

[0108] S1: When the upper plate 1 and the lower plate 2 are formed, the upper embedding groove 11 and the lower embedding groove 21 are reserved respectively;

[0109] Specifically, this method first determines the shape, quantity, spacing and installation angle of the guide element 4 in each interlayer structure based on the target flow direction, flow rate and flow field distribution of the water flow in each layer, and then determines the positions of the upper embedded groove 11 and the lower embedded groove 21 based on the above guide element data.

[0110] The method for pre-forming the upper embedding groove 11 and the lower embedding groove 21 can be as follows: When casting the upper layer plate 1 and the lower layer plate 2, install the groove forming component in the corresponding template, so that the upper embedding groove 11 is formed on the side of the upper layer plate 1 facing the lower layer plate 2, and the lower embedding groove 21 is formed on the side of the lower layer plate 2 facing the upper layer plate 1. The upper embedding groove 11 and the lower embedding groove 21 are aligned with each other to receive the upper end 41 and the lower end 42 of the same guide member 4, respectively. After the layer plate reaches the required strength for installation, remove the groove forming component and clean the embedding groove to form the upper embedding groove 11 and the lower embedding groove 21.

[0111] S2: Install the flow guide 4 between the upper plate 1 and the lower plate 2, so that the upper end 41 and the lower end 42 of the flow guide 4 extend into the upper mounting groove 11 and the lower mounting groove 21 respectively.

[0112] Specifically, the guide component 4 is first inserted into the interlayer channel 3 between the upper plate 1 and the lower plate 2 in an inclined or horizontal posture. Then, the upper end 41 of the guide component 4 is extended into the upper mounting groove 11, and the guide component 4 is lifted upwards using the assembly allowance provided by the upper mounting groove 11. Subsequently, the guide component 4 is rotated or translated so that its lower end 42 passes over the opening of the lower mounting groove 21 and aligns with it. Then, the guide component 4 is moved downwards so that its lower end 42 enters the lower mounting groove 21. After the guide component 4 is in place, its installation position, guiding angle, and vertical posture are adjusted, and its position is maintained by temporary positioning components to prevent movement during subsequent pouring. In practical applications, the position of the guide component 4 can also be pre-fixed by pouring the lower mounting groove 21.

[0113] When the flow guide 4 is formed by splicing multiple flow guide units 43, each flow guide unit 43 can be sent into the interlayer channel 3, then aligned sequentially along the height direction, and connected by the splicing structure 44 to form a complete flow guide 4.

[0114] S3: A forming support 9 is provided at the opening of the upper fixed groove 11 and the opening of the lower fixed groove 21. The end face of the forming support 9 is flush with the surface of the corresponding layer plate facing the interlayer channel 3.

[0115] The forming support component 9 can be composed of two detachable and splicable plates. The opposing sides of the two plates each have clearance notches that match the outer contour of the guide component 4. After the two plates are joined from both sides of the guide component 4, they together enclose the guide component 4 and seal the opening of the corresponding embedding groove. The position of the forming support component 9 is adjusted so that the end face of the forming support component 9 is flush with the surface of the corresponding layer plate facing the interlayer channel 3. The forming support component 9, the groove wall of the embedding groove, and the corresponding end of the guide component 4 together define the casting space.

[0116] As one implementation method, such as Figure 2 As shown, the molded support 9 can cover the outside of the groove, so that the inner end face of the molded support 9 is flush with the surface of the layer plate; after casting, the molded support 9 can be removed.

[0117] As another implementation method, such as Figure 7 As shown, the molded support 9 can cover the inside of the groove, so that the outer end face of the molded support 9 is flush with the surface of the layer plate; after casting, the molded support 9 and the embedded solid are integrated, that is, the molded support 9 and the cement-based casting material together form the upper cast embedded solid 5 or the lower cast embedded solid 6.

[0118] S4: Pour cement-based casting material into the upper embedding groove 11 and the lower embedding groove 21, and let it solidify to form the upper embedded solid 5 and the lower embedded solid 6.

[0119] The cement-based casting material can be fine aggregate concrete, cement mortar, or cement-based grout. The upper embedding groove 11 can be grouted through the pre-reserved grouting channel 12, and the lower embedding groove 21 can be grouted through the groove opening. During the grouting process, the cement-based casting material can be pressurized during grouting. After grouting, the positions of the formed support component 9 and the temporary positioning component are maintained until the cement-based casting material solidifies to form the upper embedded solid 5 and the lower embedded solid 6.

[0120] In the embodiment where the molded support 9 covers the outside of the groove, the molded support 9 is removed after the upper cast-in-place solid 5 and the lower cast-in-place solid 6 have reached the demolding strength. After removing the molded support 9, the exposed surfaces of the upper cast-in-place solid 5 and the lower cast-in-place solid 6 at the groove are flush with the surfaces of the corresponding layers facing the interlayer channel 3. The molding quality of the groove is then checked, and burrs or local high points are removed if necessary.

[0121] In this construction method, the reserved embedding groove can provide lifting and rotation margin for the flow guide 4, thereby reducing the difficulty of its installation in the narrow interlayer channel 3; the cast-in-place embedded body formed by post-casting can stably fix the flow guide 4 and transfer the water flow load to the layer plate; the coplanar molded support 9 can form a connection area flush with the surface of the layer plate after demolding, avoiding the appearance of an outward fixed structure at the root of the flow guide 4, thereby reducing local eddies and turbulence and improving the flow guiding quality.

[0122] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
