Description

Technical Field

[0001] This invention relates to the field of flood control engineering technology, specifically to a detachable flood wall baffle structure and its installation and conversion method between normal and flood seasons. Background Technology

[0002] With the rapid development of the social economy and the wave of urbanization, the development density in areas along rivers has increased significantly. According to current standards such as the Flood Control Standard (GB50201-2014), the design standards of many early dikes are outdated and no longer meet current safety requirements, leading to an increasing number of dike heightening and reinforcement projects along major rivers.

[0003] Traditional reinforced concrete flood walls have significant drawbacks when faced with the need for substantial increases in height: on the one hand, the towering concrete structures obstruct the riverside view corridor, damaging the permeability and continuity of the shoreline landscape, which not only harms the urban landscape but also hinders the development of the waterfront tourism economy; on the other hand, their construction relies on large machinery and a wide working surface for formwork, reinforcement, and maintenance, while old dikes in the core urban areas are often cramped, with the river in front and buildings behind, and the narrow site greatly increases the difficulty and cost of construction.

[0004] Against this backdrop, aluminum alloy prefabricated flood walls are gaining popularity due to their modularity and convenience. These walls utilize high-strength, corrosion-resistant aluminum alloy profiles, combining lightweight design with high load-bearing capacity, significantly reducing transport difficulty and adapting to harsh aquatic environments. Their core lies in modular design and quick-locking connection technology. Precision-machined column slots and water-blocking plates interlock, coupled with embedded rubber sealing strips, enabling rapid assembly and efficient water sealing without tools or with minimal tools. This structure supports repeated disassembly and long-term reuse. Previously, it was primarily used in inland lakes or small rivers with slow flow and low water levels, but its application in raising levees in densely populated old urban areas is still limited. The conventional approach is to hastily install flood walls during the flood season or after warnings are issued, often missing the optimal defense opportunity due to delayed response. Conversely, choosing to permanently install them in advance for safety reasons repeats the mistake of obstructing the river view, thus losing aesthetic advantages.

[0005] In response to the aforementioned pain points of "difficulty in balancing landscape and flood control" and "conflict between emergency response and permanent facilities," the industry urgently needs a new type of detachable flood wall structure that combines the functions of a guardrail and water barrier, along with its installation and conversion methods for normal and flood seasons. The aim is to achieve efficient conversion between scenic views during peacetime and flood control during flood season. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by providing a detachable flood control wall structure and its installation and flood-control conversion method, enabling efficient conversion between normal viewing and flood control.

[0007] To achieve the above objectives, the detachable flood wall baffle structure designed in this invention is suitable for prefabricated flood wall column systems, including a protective unit and a flood control unit; The protective unit includes a protective baffle and a protective railing. The protective baffle has at least one horizontal groove that runs through the front and back. The protective railing is horizontally installed in the horizontal groove and fixed inside the groove. The protective baffle is detachably inserted between two adjacent posts. The flood control unit includes a connecting fastener and a flood control baffle. The connecting fastener is located on one side of the protective baffle and has a through groove that corresponds to the position of the horizontal groove on the protective baffle. The flood control baffle is detachably installed between the connecting fastener and the protective baffle.

[0008] Preferably, the protective barrier has two horizontal grooves running vertically through the barrier, and two guardrails are installed horizontally within each groove. The ends of each guardrail are fixed to the left and right ends of the corresponding groove. In this design, the protective barrier has two horizontal grooves running vertically through the barrier, each with a guardrail, forming a double-layered guardrail structure. On one hand, the double-guardrail arrangement significantly improves the overall rigidity and fall-prevention safety performance of the guardrail, meeting the height and strength requirements of public places. On the other hand, the combination of the grooves and guardrails makes the protective barrier structure more stable, enhances its resistance to lateral deformation, and maintains good shape stability even under water pressure during the flood season.

[0009] Preferably, the connecting fastener is a snap-on plate, with two snap-on bolts on each of its left and right sides. These bolts secure the snap-on plate to the water-blocking side of the protective baffle. Two tightening bolts are located on one side of the snap-on plate to secure the flood control baffle. In this design, the connecting fastener specifically adopts a snap-on plate structure. Two snap-on bolts on each of the left and right sides of the snap-on plate secure it to the water-blocking side of the protective baffle, while two tightening bolts on the other side secure the flood control baffle. This bolt connection method is simple in structure, easy to assemble and disassemble, and can be completed without special large tools. The multi-point distribution of the snap-on bolts ensures the reliability and uniform force distribution of the connection between the snap-on plate and the protective baffle. The tightening bolts can apply adjustable clamping force to the flood control baffle during the flood season, further improving the water-blocking sealing effect and impact resistance.

[0010] Preferably, the protective unit further includes protective sealing strips, which are located at both ends of one side of the protective baffle, vertically oriented, with one strip on each side. The flood control unit also includes rubber strips and flood control sealing strips. The rubber strips are located on both sides inside the connecting fasteners, and the flood control sealing strips are located on the left and right sides of the connecting fasteners, vertically oriented, with one strip on each side. In this design, the protective unit is equipped with vertical protective sealing strips, and the flood control unit is equipped with rubber strips and vertical flood control sealing strips, thereby forming a multi-layered, multi-position sealing barrier between the protective baffle and the column, between the connecting fasteners and the protective baffle, and on the left and right sides of the flood control baffle: the protective sealing strips seal the joint between the protective baffle and the column, the rubber strips fill the internal cavity of the connecting fasteners to prevent the flood control baffle from shaking during installation and to act as a buffer to stop water leakage, and the flood control sealing strips further block the leakage channels on the water-blocking path. The multiple seals work together to significantly improve the water-stopping reliability of the overall structure and prevent flood leakage.

[0011] Preferably, the flood control barrier has a multi-cavity hollow structure. In this design, the flood control barrier adopts a multi-cavity hollow structure, which significantly reduces the weight of a single barrier while ensuring its water-blocking strength and impact resistance. This facilitates manual handling, on-site transfer, and rapid installation, further shortening the deployment time of the flood control barrier during the flood season and improving emergency response efficiency.

[0012] Preferably, the flood control baffle has a three-cavity hollow structure, including three models: a left-flat-right-concave baffle, a left-convex-right-concave baffle, and a left-convex-right-flat baffle. Adjacent flood control baffles are joined by inserting the convex end into the concave end. The inner wall of the concave end of the left-flat-right-concave baffle and the left-convex-right-concave baffle are provided with a vertical flood control sealing strip. In this design, the flood control baffle is further designed as a three-cavity hollow structure, and is divided into three models: left-flat-right-concave, left-convex-right-concave, and left-convex-right-flat. Adjacent flood control baffles are joined by inserting the convex end into the concave end, resulting in a tight fit and accurate alignment. The length can be flexibly combined according to the column spacing. The inner wall of the concave end of the left-flat-right-concave baffle and the left-convex-right-concave baffle are provided with a vertical flood control sealing strip, which further improves the sealing performance at the joints between the baffles, forming a continuous and reliable water barrier.

[0013] Preferably, the connecting fasteners are permanently fixed to one side of the protective baffle. The protective sealing strip, rubber strip, and flood control sealing strip are installed together with the flood baffle. In this design, the connecting fasteners are permanently fixed to one side of the protective baffle, eliminating the need for annual pre-flood season installation. During the flood season, only the flood baffle and sealing strips need to be installed to quickly form a water barrier, further improving emergency response speed. At the same time, the protective sealing strip, rubber strip, and flood control sealing strip are only installed with the flood baffle during the flood season, avoiding the aging, cracking, or failure of rubber seals due to long-term exposure to sun and rain, extending the service life of the sealing components, and reducing replacement frequency and maintenance costs.

[0014] Preferably, the protective baffle has mounting through holes at the positions corresponding to the bolts on the snap-on plates, and these through holes are located on the water-retaining side of the protective baffle. In this design, the mounting through holes corresponding to the bolts on the snap-on plates are located on the water-retaining side of the protective baffle. This arrangement ensures that the bolt holes and bolt heads are not visible when viewed from one side of the railing during non-flood seasons, maintaining the cleanliness and aesthetics of the waterfront viewing side of the protective baffle and preserving the waterfront landscape effect. Simultaneously, installation and maintenance operations are all carried out from the water-retaining side, facilitating work for construction personnel and avoiding interference with traffic and the landscape on the urban viewing side.

[0015] Preferably, the protective barriers and guardrails are made of aluminum alloy. The flood control barriers and connecting fasteners are also made of aluminum alloy; the protective sealing strips, rubber strips, and flood control sealing strips are made of synthetic rubber. In this design, the protective barriers, guardrails, flood control barriers, and connecting fasteners are all made of aluminum alloy, which has advantages such as light weight, high strength, and corrosion resistance. It is particularly suitable for use in humid water environments and outdoor conditions exposed to sun and rain for extended periods, and is easy to handle and assemble. The protective sealing strips, rubber strips, and flood control sealing strips are made of synthetic rubber, which has good elasticity, compression resilience, weather resistance, and aging resistance, ensuring long-term reliable sealing performance.

[0016] A method for installing and switching between flood season and normal season using a detachable flood control wall panel structure includes the following steps: Step S1, Installation during non-flood season: Insert the protective barrier between two adjacent posts and fix it in place. Fix the connecting fasteners to one side of the protective barrier so that the guardrail is exposed to form a guardrail. Step S2, Flood Season Installation: Install the rubber strip between the connecting fastener and the protective baffle; install the protective sealing strip and the flood control sealing strip into the reserved slots respectively; install the flood control baffle between the connecting fastener and the protective baffle and tighten it. Step S3, Post-Flood Dismantling: Dismantle the flood control baffle and each sealing strip in the reverse order of Step 2, while retaining the protective baffle and connecting fasteners.

[0017] Compared with existing technologies, this invention has the following advantages: The flood control wall baffle structure provided by this invention includes two parts: a protective unit and a flood control unit. The protective baffle and the protective railing are integrated and detachably inserted between two adjacent columns. The flood control baffle is detachably installed between the connecting fastener and the protective baffle, thus forming a "double-plate replacement" mode. This brings the following comprehensive effects: Firstly, during the non-flood season, only the protective barriers and railings are retained as guardrails. They have good transparency and can preserve the open view of the riverside and riverside areas, meet the sightseeing and leisure needs of citizens, avoid the obstruction and visual oppression of the shoreline landscape by traditional solid flood walls, and at the same time have sufficient guardrail strength and height to ensure pedestrian safety. Secondly, during the flood season, there is no need to dismantle the pillars or change the foundation. Flood barriers can be quickly installed on the existing pillar system to form a water barrier, reducing flood prevention preparation time from "hours" to "minutes" and significantly improving the emergency response capability to sudden floods. Third, this invention is compatible with various aluminum alloy prefabricated flood wall column systems commonly used in the market, replacing their ordinary aluminum alloy baffles. Existing facilities can be given "dual-use" function in both normal and flood seasons simply by replacing the baffle components. It is especially suitable for low-cost upgrading and renovation of old flood control facilities, and its promotion value and economic benefits are significant. Fourth, as a permanent fixed component, the column does not require frequent disassembly and assembly. The protective baffle and flood control baffle are stored and used separately, avoiding problems such as wear of connectors and loss of components, extending the service life of the overall structure, and reducing maintenance costs such as manpower and logistics. Fifth, the plug-in connection and the detachable installation method of the fasteners ensure the tightness of the connection between the baffle and the column, and between the baffles themselves, as well as the overall stability of the structure, which can effectively resist the impact of floods and ensure flood control safety.

[0018] The provided installation and flood / normal season conversion method, through a clear three-stage operation process of "installation during the non-flood season—addition during the flood season—disassembly after the flood season," fully leverages the "dual-use" design advantage of this invention: during the non-flood season, the installation of the protective barrier and connecting fasteners is completed in one go, allowing for long-term use as a guardrail; during the flood season, only the rubber strips, sealing strips, and flood control barriers need to be quickly added and tightened to complete the deployment of the water barrier; after the flood season, the guardrail can be restored to its original state by reversing the operation. This method features clear operation steps, rapid conversion, and high repeatability. Furthermore, the rubber sealing components are only installed during the flood season, effectively avoiding long-term exposure and aging, further reducing overall operation and maintenance costs, and facilitating implementation by management departments and personnel training.

[0020] The components in the diagram are labeled as follows: Protective Unit 1, Protective Baffle 11, Protective Railing 12, Flood Control Unit 2, Flood Control Baffle 21, Left Flat Right Concave Baffle 211, Left Convex Right Concave Baffle 212, Left Convex Right Flat Baffle 213, Buckle 22, Rubber Strip 23, Flood Control Sealing Strip 24, Fastening Bolt 25, Buckle Bolt 26. Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0022] For ease of description, the "water-retaining side" mentioned in this specification refers to the side of the flood wall facing the water, i.e., the side that bears the pressure of floodwater during the flood season; the "viewing side" refers to the side of the flood wall away from the water, i.e., the side that is used for pedestrian passage and viewing during the non-flood season. The "column" mentioned refers to the standard aluminum alloy column in the prefabricated flood wall column system, which has slots on both sides to accommodate baffles. It is a component known in the art. For example, 45 series or 60 series columns conforming to the T / GDJSKB group standard "Prefabricated Aluminum Alloy Flood Retaining Wall" can be used. The center-to-center distance between adjacent columns is generally 1.0m to 1.5m.

[0023] Example like Figures 1-3 As shown, a detachable flood wall baffle structure is applicable to prefabricated flood wall column systems, comprising two parts: a protective unit 1 and a flood control unit 2.

[0024] The protective unit 1 consists of a protective baffle 11, a protective railing 12, and a protective sealing strip 13.

[0025] The protective baffle 11 is integrally formed from 6063-T5 or 6082-T6 extruded aluminum alloy profiles, and is rectangular in shape. Its length is determined by the column spacing (1200mm in this embodiment), its height is 1000mm, and its thickness is 45mm. The surface is anodized, with an oxide film thickness of not less than 15μm to meet the weathering requirements of more than 10 years in a waterfront outdoor environment. The protective baffle 11 has two horizontal grooves running vertically from front to back, each 50mm wide and 60mm high. The center of the upper horizontal groove is 120mm from the top surface of the protective baffle 11, and the center of the lower horizontal groove is 120mm from the bottom surface of the protective baffle 11.

[0026] The guardrail 12 consists of two sections, made of the same grade of extruded aluminum alloy, with a cross-section of 40mm×40mm square tubing and a wall thickness of 3mm. They are horizontally positioned within upper and lower horizontal slots. Each guardrail 12 is fixed at both ends to the corresponding horizontal slot using M8 stainless steel hexagonal screws. The exposed screw portions are milled, polished, and then surface-treated. This double-guardrail arrangement meets the safety requirements of GB50763 "Barrier-Free Design Code" and other standards for public waterfront guardrails, which stipulate a height of not less than 1.10m and the ability to withstand a horizontal thrust of not less than 1.0kN / m.

[0027] The protective sealing strip 13 is made of EPDM synthetic rubber by extrusion molding, with a Shore hardness of 60±5HA, a V-shaped cross-section with a lip, and a width of 12mm. The protective sealing strip 13 is located at the left and right ends of the water-blocking side of the protective baffle 11, in a vertical direction, with one strip on each side. Its two ends respectively abut against the upper and lower edges of the protective baffle 11 and are pressed into the sealing groove of the column, thereby achieving vertical water stop between the protective baffle 11 and the column.

[0028] At the left and right ends of the water-blocking side of the protective baffle 11, two countersunk mounting through holes are made at the positions corresponding to the buckle bolts 26 described later, for a total of 4 through holes (covering claim 8). The center distance of the through holes from the left / right edge of the protective baffle 11 is 25mm, the center distance between the upper and lower holes is 600mm, the diameter of the through holes is Φ9mm, and the diameter of the countersunk holes is Φ16mm. The through holes are only made on the water-blocking side, and the outer surface of the viewing side remains flat, without any bolt holes or bolt heads, ensuring the cleanliness and aesthetics of the viewing side.

[0029] The flood control unit 2 consists of a flood control baffle 21, a buckle plate 22, a rubber strip 23, a flood control sealing strip 24, a fastening bolt 25, and a buckle plate bolt 26.

[0030] The buckle plate 22 is made of 6082-T6 extruded aluminum alloy profile, in the shape of a rectangular frame, with an outer cross-sectional dimension of 80mm×55mm, a wall thickness of 4mm, and a length the same as that of the protective baffle 11. The buckle plate 22 has two horizontal grooves running vertically from top to bottom, with a groove width of 50mm and a net height of 60mm. The groove position and dimensions are the same as the horizontal grooves on the protective baffle 11 and are horizontally aligned. Two buckle bolts 26 are provided on each of the left and right sides of the buckle plate 22 (a total of 4). The buckle bolts 26 are made of M8×60 hot-dip galvanized high-strength carbon steel (performance grade 8.8), with a zinc layer thickness of not less than 40μm. In use, the buckle bolts 26 pass through the side wall of the buckle plate 22 and the protective sealing strip 13 from the outside of the buckle plate 22, are inserted into the installation through-hole of the protective baffle 11, and are locked from the viewing side with matching nuts. The tightening torque is controlled between 20 and 25 N·m, permanently fixing the buckle plate 22 to the water-blocking side of the protective baffle 11.

[0031] Two fastening bolts 25 are installed on the right side of the buckle plate 22 (i.e., the side away from the protective baffle 11). The fastening bolts 25 are made of M12×80 hot-dip galvanized high-strength carbon steel bolts, which are horizontally inserted through the internal threaded holes on the side wall of the buckle plate 22. After being screwed in, they are used to press the flood control baffle 21 from the outside in, thereby eliminating the gap between the flood control baffle 21 and the buckle plate 22 and the protective baffle 11. A vertical flood control sealing strip 24 is installed on the inner wall of each of the left and right sides of the buckle plate 22. The flood control sealing strip 24 is made of EPDM rubber extrusion molding, with a D-shaped cross section with double lips, and has the same Shore hardness as the aforementioned protective sealing strip 13.

[0032] The rubber strip 23 is a solid EPDM square strip with a cross-section of 10mm×20mm. It is arranged at the upper and lower ends of both sides inside the buckle plate 22 to fill the cavity between the buckle plate 22 and the protective baffle 11, prevent the flood control baffle 21 described later from shaking during the insertion process, and play a buffering and auxiliary water-stopping role when subjected to flood pressure during the flood season.

[0033] The flood control baffle 21 is a three-chamber hollow structure, integrally formed from 6082-T6 extruded aluminum alloy profiles. Its dimensions are: height 1000mm (same height as the protective baffle 11), thickness 45mm, chamber wall thickness 3.5mm, and a unit length weight of approximately 6.8kg / m. It is about 55% lighter than a solid aluminum alloy plate, facilitating manual handling. The flood control baffle 21 is available in three models: Left flat and right concave baffle 211: The left end face is flat, and the right end face is a groove (groove depth 20mm, inner width 20mm). A vertical flood control sealing strip 24 is embedded on the upper and lower sides of the inner wall of the concave end; used as the left end plate of a section of flood control wall. Left-convex-right-concave baffle 212: The left end face is a 20mm×20mm convex end, and the right end face is a groove of the same specification. The inner wall of the concave end is also provided with two flood-proof sealing strips 24; used as an intermediate splicing plate; Left-convex, right-flat baffle 213: The left end face is convex and the right end face is flat; it is used as the right end plate of a section of flood control wall.

[0034] Adjacent flood control baffles 21 are joined by inserting the left convex end into the right groove of the preceding baffle. The vertical water-stopping effect at the joint is achieved by the flood control sealing strip 24 on the inner wall of the concave end between the convex end and the groove. If the column spacing is 1200mm, the typical arrangement is: 1 left flat right concave baffle 211 + N left convex right concave baffles 212 + 1 left convex right flat baffle 213 (N can be 0 or more, adjusted according to the net column spacing).

[0035] On-site construction and the transition between normal and flood seasons shall be implemented according to the following steps: Step S1: Installation during non-flood season (one-time construction) S1.1 After the prefabricated flood control wall columns have been positioned and their verticality has been corrected (allowable deviation ≤3mm), the protective baffle 11 of the present invention is inserted from top to bottom into the limiting block at the bottom of the column along the slots of two adjacent columns, replacing the traditional ordinary aluminum alloy baffle. When inserting, make sure that the four countersunk installation through holes on the water-blocking side of the protective baffle 11 face the water-blocking side. S1.2 Attach the buckle plate 22 to the protective baffle 11 from the water-blocking side, align the four countersunk mounting holes on the protective baffle 11, and screw in the four buckle plate bolts 26 in sequence, and tighten them to 20-25 N·m with a torque wrench; After steps S1.1 and S1.2 are completed, the following will be formed: Figure 1The "protective baffle 11 + double-layer protective railing 12 + permanent fixed buckle 22" shown is the normal guardrail configuration, which is operated in this state for a long time during the non-flood season. At this time, the protective baffle 11 and the protective railing 12 together form a guardrail with good transparency, and the view from the viewing side is not blocked by the buckle 22.

[0036] Step S2: Install during the flood season (emergency deployment) S2.1 After receiving the flood warning, first install the rubber strip 23 at both ends of the upper and lower grooves between the buckle plate 22 and the protective baffle 11; S2.2 Insert the protective sealing strip 13 into the reserved grooves at both ends of the water-blocking side of the protective baffle 11; S2.3 Insert the flood control sealing strips 24 into the reserved grooves on the left and right sides of the buckle plate 22 respectively, and also insert two flood control sealing strips 24 into the reserved grooves on the inner wall of the concave end of the "left flat right concave baffle 211" and the "left convex right concave baffle 212" respectively. S2.4 Following the sequence of “left flat right concave baffle 211 → left convex right concave baffle 212 → … → left convex right concave baffle 212 → left convex right flat baffle 213”, the flood control baffle 21 is inserted from top to bottom into the cavity between the buckle plate 22 and the protective baffle 11, and adjacent flood control baffles 21 are joined together by inserting the convex and concave ends. S2.5 Finally, tighten the two fastening bolts 25 on the right side of the buckle plate 22 in sequence, with the tightening torque controlled at 35-40 N·m, so that the flood control baffle 21 is evenly pressed against the protective baffle 11, squeezing the flood control sealing strips 24, rubber strips 23 and protective sealing strips 13 to form multiple water-stopping barriers.

[0037] For a single-span flood control wall section with a length of 100m and a height of 1.0m, the time required for two workers to complete steps S2.1 to S2.5 is about 18 to 22 minutes, which is about 90% shorter than the traditional "removal of guardrails - reinstallation of columns - hoisting of baffles" scheme, which takes an average of 3 to 4 hours. This truly reduces flood control preparation time from hours to minutes.

[0038] Step S3: Post-flood dismantling (restoring the guardrail to its original state) Following the reverse order of steps S2.5→S2.1, loosen the tightening bolts 25, pull out the flood control baffle 21, remove the flood control sealing strip 24, the protective sealing strip 13 and the rubber strip 23, clean and dry the above-mentioned sealing components and flood control baffle 21 and store them in the warehouse; leave the buckle plate 22 and buckle plate bolts 26 in their original positions and restore the guardrail to its non-flood season form.

[0039] The three-stage method of "S1 initial installation - S2 installation during the flood season - S3 disassembly after the flood season" ensures that rubber seals (protective sealing strip 13, rubber strip 23, and floodproof sealing strip 24) are only exposed to sunlight and rain for a short period during the flood season, avoiding long-term failure modes such as ultraviolet aging, cracking, and permanent compression deformation. It is estimated that the overall replacement cycle of the seals can be extended from 3-5 years to 8-10 years, significantly reducing operation and maintenance costs.

[0040] Comparative Example The traditional solution also uses a prefabricated aluminum alloy column system (the column spacing is also 1200mm, and the column specifications are the same as in Example 1), but only ordinary aluminum alloy baffles are inserted between the columns. These ordinary baffles are three-cavity hollow aluminum alloy profiles with a height of 1000mm and a thickness of 45mm. They do not have horizontal through slots, any guardrails, or components such as buckles 22 or fastening bolts 25. The sealing relies only on the V-shaped rubber strip on the side of the column slot and the bottom sealing strip at the bottom of the baffle.

[0041] (I) Operation during non-flood season Because the ordinary aluminum alloy baffle is a closed panel, if it is permanently installed between the columns in advance, it will form a solid barrier about 1.0m high, completely blocking the riverside view and disrupting the permeability and continuity of the shoreline landscape. If it is not installed during normal times and only installed in a rush before the flood season, the baffle will be stored in a warehouse for a long time, but the column system will be exposed. This requires the installation of temporary guardrails to ensure pedestrian safety, and it will also result in messy column remnants that are out of place with the waterfront landscape. More importantly, if the top of the columns is to function as a guardrail, an independent guardrail needs to be installed separately and removed before the flood season, requiring an additional 80,000 to 100,000 yuan per kilometer of flood control wall per year for dismantling and installation labor costs.

[0042] (II) Emergency Installation during Flood Season When using this traditional method to deal with sudden floods, the temporary guardrails on the upper part of the columns must first be removed, and then ordinary aluminum alloy baffles must be transported from the warehouse to the site, inserted into the column slots from top to bottom, and finally locked with the top fastening device. Comparative testing showed that for the same 100m long, 1.0m high single-span flood control wall section, two workers need to complete the entire process of "guardrail removal—baffle transport—baffle hoisting—seal installation—fastening," which takes approximately 3 hours and 40 minutes, about 10 times longer than Embodiment 1 of this invention. Furthermore, in the event of a sudden, short-duration flood, the delayed response can easily lead to missing the optimal defense opportunity.

[0043] (III) Post-flood dismantling and aging issues After the flood recedes, all ordinary aluminum alloy retaining walls need to be removed to restore the landscape; the process is the reverse of the installation. All retaining walls and sealing components must be removed and stored. The V-shaped sealing strips on the side of the column slots have an average lifespan of only 2-3 years due to frequent disassembly and pulling during the alternation of flood and non-flood seasons. Furthermore, since there is no lateral pressure from the retaining plate 22 on the retaining wall, the contact pressure between the retaining wall and the column depends solely on the elasticity of the sealing strip itself. The actual leakage rate can reach 1.5-2.5 L / (h·m), which is close to the upper limit requirement of the T / GDJSKB standard for "non-sealed (Type B) retaining walls".
