Description

Technical Field

[0001] This invention relates to the field of flood control wall technology in water conservancy projects, and particularly to a flood control wall heightening device. Background Technology

[0002] With the rapid development of the social economy and the continuous acceleration of urbanization, the population of cities and towns has grown rapidly, and the intensity of land development along rivers and streams has been increasing. The flood control capacity of many early-built dikes can no longer meet the current and future flood control safety requirements, and in recent years, the number of engineering projects to raise and reinforce old dikes along major rivers has been increasing year by year.

[0003] Currently, the mainstream technical solution for raising old dikes is the reinforced concrete flood control wall structure. This solution typically involves directly pouring reinforced concrete walls on the top of the existing dike or on the water-facing side. However, this traditional method has significant drawbacks: First, when the height is substantial, the towering concrete barrier severely obstructs the view of the river for pedestrians along the river, disrupting the permeability and landscape continuity of the riverside, affecting not only the urban landscape but also directly hindering the development of tourism that relies on river views. Second, traditional reinforced concrete flood control wall construction requires a large working area for formwork erection, rebar tying, and concrete curing. However, many old dikes located in the core urban areas have extremely limited riverside space, with roads or buildings behind them and the river in front. The narrow construction site makes it impossible for large machinery to operate, greatly increasing the difficulty of project implementation and construction costs. In addition, reinforced concrete structures have long construction cycles and are greatly affected by weather, making it difficult to meet the needs of rapidly improving flood control capabilities.

[0004] To overcome the aforementioned problems, a few regions have experimented with aluminum alloy prefabricated flood walls. While this solution offers advantages such as modularity and ease of installation, it is currently mainly used for lake damming or localized sections of small rivers with low flow velocities and low flood control heights. Its application in river flood control, especially in large rivers, is limited. Existing aluminum alloy prefabricated flood walls have significant shortcomings when facing complex hydrological conditions: their structural rigidity and overall stability are relatively weak, and their flood response speed is insufficient to cope with sudden flash floods or floods exceeding standard levels. In high-velocity, high-impact river environments, their overturning resistance and seepage prevention performance often fail to meet high-standard flood control requirements, posing significant safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a flood control wall heightening device to solve the problem of significant safety hazards caused by the relatively weak rigidity and overall stability of existing flood control wall heightening devices.

[0006] To solve the above-mentioned technical problems, the present invention provides a flood control wall heightening device, characterized in that it includes a reinforced concrete base, a column assembly, and multiple baffles; The top of the reinforced concrete base is provided with a first column mounting groove, and at least one second column mounting groove is provided sequentially along the first horizontal direction from the first column mounting groove. The column assembly includes a first column and at least one second column, wherein the first column is installed in the first column mounting slot and the second column is installed in the second column mounting slot in sequence; A baffle is installed between the first column and the adjacent second column, and a baffle is installed between two adjacent second columns; The first column mounting slot, the second column mounting slot, the first column, the second column, and the baffle are mutually self-locking.

[0007] Optionally, after the lower part of the second column is installed into the second column mounting groove, the second column has a first position and a second position relative to the second column mounting groove. When the second column is in the first position relative to the second column mounting groove, the second column can move vertically upward relative to the second column mounting groove and can move horizontally relative to the second column mounting groove. When the second column is in the second position relative to the second column mounting groove, the second column mounting groove restricts the second column from moving vertically, and the second column can move in the opposite direction of the first horizontal direction relative to the second column mounting groove. After the lower part of the first column is installed into the first column mounting slot, the first column has a third position and a fourth position relative to the first column mounting slot. When the first column is in the third position relative to the first column mounting slot, the first column can move vertically upward relative to the first column mounting slot and can move in the opposite direction relative to the first column mounting slot in the first horizontal direction. When the first column is in the fourth position relative to the first column mounting slot, the first column mounting slot restricts the first column from moving vertically, and the first column can move in the first horizontal direction relative to the first column mounting slot.

[0008] Optionally, the first column mounting slot and the second column mounting slot are the same, and the first column and the second column are the same.

[0009] Optionally, the first column mounting groove includes a main groove cavity and a limiting cavity connected to the main groove cavity. The opening of the main groove cavity is vertically upward, and the opening of the limiting cavity is set in a first horizontal direction. The bottom of the limiting cavity is flush with the bottom of the main groove cavity, and the top of the limiting cavity is lower than the top of the main groove cavity. When the lower part of the first column is in a third position relative to the first column mounting groove, the lower part of the first column is located in the main groove cavity. When the lower part of the first column is in a fourth position relative to the first column mounting groove, the lower part of the first column is partially located in the main groove cavity and partially located in the limiting cavity.

[0010] Optionally, the first column includes a column main body and a column sub-body, the column main body and the column sub-body are connected, the bottom of the column main body is flush with the bottom of the column sub-body, the top of the column sub-body is lower than the top of the column main body, and the vertical height of the column sub-body is exactly equal to the vertical height of the limiting cavity.

[0011] Optionally, the main cavity includes two cuboid main cavities and a cuboid connecting cavity. The bottoms and tops of the main cavities and the connecting cavity are flush and their openings face upwards. The two main cavities are arranged in a direction perpendicular to the first horizontal direction. The connecting cavity connects the two main cavities and is perpendicular to the first horizontal direction.

[0012] Optionally, the main body of the column includes two main webs, which are arranged in a direction perpendicular to the first horizontal direction. The secondary body of the column connects the two main webs, and the bottom of the main webs is flush with the bottom of the secondary body of the column, while the top of the secondary body of the column is lower than the main webs.

[0013] Optionally, it may also include a plurality of column sleeves, the column sleeves being cast on the reinforced concrete base, and the first column mounting groove and the second column mounting groove being formed in the column sleeves.

[0014] Optionally, it also includes a bolt sleeve and a bolt, the bolt sleeve being cast on the reinforced concrete base, and the bolt being used to connect the bolt sleeve to the first column and the second column.

[0015] Optionally, the reinforced concrete base includes a main wall, multiple fishbone walls, and multiple reinforcing bars. The reinforcing bars are connected to the main wall and extend out of the main wall. The multiple fishbone walls are perpendicular to the main wall and arranged sequentially along the main wall. The first column mounting groove and the second column mounting groove are formed on the top of the main wall.

[0016] The flood control wall heightening device provided by this invention has the following beneficial effects: First, a reinforced concrete base provides a stable foundation for the entire heightening device, effectively resisting the enormous impact and overturning moment of high-velocity river water. By pre-setting first and second column mounting slots on the reinforced concrete base, and utilizing the self-locking structure between the first and second columns, and between the baffle and the first and second columns, rapid positioning and installation are achieved. This self-locking structure also enhances the overall strength and rigidity of the flood wall heightening device, increasing its safety. This "prefabricated + assembled" model, compared to traditional cast-in-place concrete walls, significantly reduces on-site wet work, accelerates construction, and is less affected by weather, meeting the urgent need to rapidly improve flood control capabilities. Simultaneously, the baffle, as the main water-blocking component, can be made of lightweight, high-strength materials (such as aluminum alloys and composite materials) as needed. Compared to an all-concrete structure, this effectively reduces the structural weight and lowers the load requirements on the base while meeting the flood control height requirements. More importantly, this structural form facilitates possible dismantling or partial replacement in the future, which is conducive to the flexible creation and maintenance of the riverside landscape.

[0017] Secondly, by first inserting the second column into the second column mounting slot and placing it in the first position, the second column can move vertically within the mounting slot for height adjustment and can also move horizontally for vertical self-locking. Then, by inserting the first column into the first column mounting slot and placing it in the third position, the first column can move vertically within the mounting slot for height adjustment and can also move in the opposite direction of the first horizontal direction for vertical self-locking. Next, the second column is placed in the second position, and the first column in the fourth position, achieving vertical self-locking for both the second and first columns. Then, baffles are inserted between the first column and adjacent second columns, and between adjacent second columns. Through the action of the baffles and the fact that the second and first columns can move in opposite directions horizontally, the first and second columns as a whole are less likely to move horizontally, thus achieving horizontal self-locking between the first and second columns. This not only simplifies the assembly process, enabling precise alignment and stable connection without the need for complex auxiliary tools, but more importantly, it allows the structure to buffer some energy when encountering floods exceeding design standards or unexpected impacts through the slight displacement of the columns within the groove, thereby improving the structure's toughness and safety redundancy.

[0018] Furthermore, by designing the first and second column mounting slots, as well as the first and second columns, to be of the same specification, a high degree of standardization and universality of the core components was achieved. This not only greatly simplifies mold design and production processes and reduces manufacturing costs, but also makes component management and installation on the construction site more convenient, avoiding installation errors caused by component confusion. Standardized components also mean higher interchangeability; when a column or baffle is damaged, it can be quickly replaced with a spare part, improving the maintenance efficiency of the device and its ability to respond to emergencies.

Figure 3 This is an exploded structural diagram of the flood control wall heightening device in an embodiment of the present invention.

Figure 5 This is a schematic diagram of the structure of the column sleeve of the flood control wall heightening device in an embodiment of the present invention. Figure 6 This is a structural schematic diagram of the column sleeve, baffle sleeve, and bolt sleeve of the flood control wall heightening device in this embodiment of the invention. This embodiment provides a flood control wall heightening device, including a reinforced concrete base 100, a column assembly 200, and multiple baffles 300. The top of the reinforced concrete base 100 is provided with a first column mounting groove 140, and at least one second column mounting groove 150 is sequentially provided along a first horizontal direction from the first column mounting groove 140. The column assembly 200 includes a first column 210 and at least one second column 220. The first column 210 is installed in the first column mounting groove 140, and the second column 220 is sequentially installed in the second column mounting groove 150. A baffle 300 is engaged between the first column 210 and an adjacent second column 220, and a baffle 300 is engaged between two adjacent second columns 220. The first column mounting groove 140, the second column mounting groove 150, the first column 210, the second column 220, and the baffle 300 are mutually self-locking.

[0028] By setting up a reinforced concrete base 100, a stable foundation is provided for the entire heightening device, effectively resisting the enormous impact force and overturning moment of high-velocity river water. By pre-setting the first column mounting slot 140 and the second column mounting slot 150 on the reinforced concrete base 100, and utilizing the self-locking structure between the first column 210 and the first column mounting slot 140, the second column 220 and the second column mounting slot 150, and the baffle 300 and the first and second columns 210 and 220, the device features rapid positioning and installation. Furthermore, the self-locking structure enhances the overall strength and rigidity of the flood wall heightening device, increasing its safety. This "prefabrication + assembly" model, compared to traditional cast-in-place concrete walls, significantly reduces on-site wet work, accelerates construction, and is less affected by weather, meeting the urgent need to rapidly improve flood control capabilities. Meanwhile, as the main water-retaining component, the baffle 300 can be made of lightweight, high-strength materials (such as aluminum alloys and composite materials) as needed. Compared to a full concrete structure, it can effectively reduce the structural weight and lower the load requirements on the base 100 while meeting the flood control height requirements. More importantly, this structural form facilitates possible disassembly or partial replacement in the future, which is conducive to the flexible creation and maintenance of the riverside landscape.

[0029] Specifically, after the lower part of the second column 220 is installed into the second column mounting groove 150, the second column 220 has a first position and a second position relative to the second column mounting groove 150. When the second column 220 is in the first position relative to the second column mounting groove 150, the second column 220 can move vertically upward relative to the second column mounting groove 150 and can move horizontally relative to the second column mounting groove 150. When the second column 220 is in the second position relative to the second column mounting groove 150, the second column mounting groove 150 restricts the second column 220 from moving vertically, and the second column 220 can move horizontally in the opposite direction relative to the second column mounting groove 150. Movement; After the lower part of the first column 210 is installed into the first column mounting groove 140, the first column 210 has a third position and a fourth position relative to the first column mounting groove 140. When the first column 210 is in the third position relative to the first column mounting groove 140, the first column 210 can move vertically upward relative to the first column mounting groove 140 and can move in the opposite direction relative to the first column mounting groove 140 in the first horizontal direction. When the first column 210 is in the fourth position relative to the first column mounting groove 140, the first column mounting groove 140 restricts the first column 210 from moving vertically, and the first column 210 can move in the first horizontal direction relative to the first column mounting groove 140.

[0030] First, the second column 220 is inserted into the second column mounting slot 150, placing it in the first position. At this position, the second column 220 can move vertically within the second column mounting slot 150 for height adjustment and can move horizontally for vertical self-locking. Then, the first column 210 is inserted into the first column mounting slot 140, placing it in the third position. At this position, the first column 210 can move vertically within the first column mounting slot 140 for height adjustment and can move in the opposite direction of the first horizontal direction for vertical self-locking. Next, the second column 220 is placed in the second position, and the first column 210 is placed in the fourth position, achieving vertical self-locking for both the second and first columns. Then, baffles 300 are inserted between the first column 210 and the adjacent second column 220, and between adjacent second columns 220. Through the action of the baffles 300, and the fact that the second columns 220 and the first column 210 are movable in opposite directions in the horizontal direction, the first column 210 and the second column 220 as a whole are less prone to horizontal movement, thus achieving horizontal self-locking of the first column 210 and the second column 220. This not only simplifies the assembly process, achieving precise alignment and stable connection without complex auxiliary tools, but more importantly, it allows the structure to buffer some energy through the slight displacement of the columns within the groove when encountering floods exceeding design standards or unexpected impacts, improving the structure's toughness and safety redundancy.

[0031] Preferably, the first column mounting slot 140 and the second column mounting slot 150 are identical, and the first column 210 and the second column 220 are identical. By designing the first column mounting slot 140 and the second column mounting slot 150, and the first column 210 and the second column 220, to be of the same specifications, a high degree of standardization and universality of the core components is achieved. This not only greatly simplifies mold design and production processes and reduces manufacturing costs, but also makes component management and installation on the construction site more convenient, avoiding installation errors caused by component confusion. Standardized components also mean higher interchangeability; when a column or baffle is damaged, it can be quickly replaced with a spare part, improving the maintenance efficiency of the device and its ability to respond to emergencies.

[0032] Specifically, the first column mounting groove 140 includes a main groove cavity 141 and a limiting cavity 142 connected to the main groove cavity 141. The opening of the main groove cavity 141 is vertically upward, and the opening of the limiting cavity 142 is set in a first horizontal direction. The bottom of the limiting cavity 142 is flush with the bottom of the main groove cavity 141, and the top of the limiting cavity 142 is lower than the top of the main groove cavity 141. When the lower part of the first column 210 is in the third position relative to the first column mounting groove 140, the lower part of the first column 210 is located in the main groove cavity 141. When the lower part of the first column 210 is in the fourth position relative to the first column mounting groove 140, the lower part of the first column 210 is partially located in the main groove cavity 141 and partially located in the limiting cavity 142. The main channel 141 provides the initial placement space and vertical movement channel for the first column 210, while the limiting cavity 142, through its opening direction and top height restriction, locks the column at a specific location after translation, achieving vertical locking. This composite channel design of "main channel + limiting cavity" is simple in structure, clearly defined in force, and can be installed and locked with only simple translation, resulting in extremely high installation efficiency. Furthermore, under water pressure, the contact surface between the limiting cavity 142 and the column can form a reliable load-bearing structure, exhibiting excellent shear and pull-out resistance.

[0033] The first column 210 includes a column main body 211 and a column sub-body 212. The column main body 211 and the column sub-body 212 are connected, and the bottom of the column main body 211 is flush with the bottom of the column sub-body 212. The top of the column sub-body 212 is lower than the top of the column main body 211, and the vertical height of the column sub-body 212 is exactly equal to the vertical height of the limiting cavity 142.

[0034] The height difference between the main body 211 and the auxiliary body 212 of the column is designed to perfectly match the main cavity 141 and the limiting cavity 142 of the mounting slot. When the column is in the fourth position, the auxiliary body 212 is fully embedded in the limiting cavity 142, while the main body 211 remains in the main cavity 141. This "embedded" fit greatly enhances the column's ability to resist overturning moments. The equal height of the auxiliary body 212 and the limiting cavity 142 ensures a perfect fit, uniform stress distribution, avoids localized stress concentration, and improves the reliability and durability of the connection.

[0035] In this embodiment, the second column mounting groove 150 is the same as the first column mounting groove 140, except that the orientation is reversed. The first column 210 is the same as the second column 220, except that the orientation is reversed.

[0036] Furthermore, the main trough 141 includes two cuboid main cavities 1411 and one cuboid connecting cavity 1412. The bottoms and tops of the main cavities 1411 and the connecting cavity 1412 are flush and their openings face upwards. The two main cavities 1411 are arranged in a direction perpendicular to the first horizontal direction. The connecting cavity 1412 connects the two main cavities 1411 and is perpendicular to the first horizontal direction. This structural design provides two independent support points for the column, effectively constraining its displacement in the direction perpendicular to the first horizontal direction (i.e., the water flow direction) and enhancing its torsional stiffness. Furthermore, the presence of the connecting cavity 1412 makes the stress distribution of the entire main trough 141 more integrated, facilitating concrete casting and ensuring the structural strength of the trough itself. This optimized cross-sectional shape significantly improves the load-bearing capacity and stability of the connection node between the reinforced concrete base 100 and the first column 210 and the second column 220 without significantly increasing the amount of material used.

[0037] Correspondingly, the main body 211 of the column includes two main webs 2111, which are arranged in a direction perpendicular to the first horizontal direction. The secondary body 212 of the column connects the two main webs 2111, and the bottom of the main webs 2111 is flush with the bottom of the secondary body 212, while the top of the secondary body 212 is lower than the main webs 2111. By designing the main body 211 of the column as two parallel main webs 2111 connected by the secondary body 212, an "I"-shaped load-bearing section is formed. This section shape has extremely high bending and shear resistance, and can withstand the bending moment generated by huge water pressure with a relatively light self-weight. Meanwhile, the two main web plates 2111 can be inserted into the two main cavities 1411 respectively, further restricting the torsion of the column, so that the entire water-blocking structure remains stable under the action of complex water flow, significantly improving the overall rigidity of the device. The corresponding column sub-body 212 can be fully embedded in the limiting cavity 142 to achieve vertical self-locking.

[0038] The flood control wall heightening device also includes multiple column sleeves 420, which are cast onto the reinforced concrete base 100. The first column mounting groove 140 and the second column mounting groove 150 are formed within the column sleeves 420. By pre-embedding precision-machined column sleeves 420 in the reinforced concrete base 100 to form the first column mounting groove 140 and the second column mounting groove 150, the dimensional accuracy and surface finish of the first column mounting groove 140 and the second column mounting groove 150 can be ensured. This is crucial for achieving precise translation and reliable self-locking of the first column 210 and the second column 220. Compared to directly pre-reserving grooves in cast-in-place concrete, using prefabricated sleeves avoids dimensional deviations in the grooves caused by formwork deformation, concrete shrinkage, etc., thus improving the interchangeability of components and the success rate of installation. Meanwhile, sleeves made of steel or other high-strength materials can significantly enhance the local compressive and impact resistance of the installation groove, preventing the base concrete from cracking due to stress concentration during installation or use, and improving the long-term durability of the joint.

[0039] The flood control wall heightening device also includes a bolt sleeve 410 and bolts. The bolt sleeve 410 is cast onto the reinforced concrete base 100, and the bolts are used to connect the bolt sleeve 410 to the first column 210 and the second column 220. By adding bolt connections as a secondary tightening measure to achieve rapid positioning and initial fixation of the columns through a self-locking mechanism, a double safety net of "self-locking positioning + bolt tightening" is formed. This design retains the advantage of convenient installation of the self-locking structure while further enhancing the connection strength between the columns and the base 100 through bolt connections, improving the safety reserve of the structure under extreme flood conditions. Bolt connections can provide reliable preload, effectively preventing minor loosening of the self-locking structure that may occur under long-term water flow pulsation or vibration, ensuring the long-term stability and reliability of the structure.

[0040] Specifically, the reinforced concrete base 100 includes a main wall 110, a plurality of fishbone walls 120 and a plurality of reinforcing bars 130. The reinforcing bars 130 are connected to the main wall 110 and extend out of the main wall 110. The plurality of fishbone walls 120 are perpendicular to the main wall 110 and are arranged sequentially along the main wall 110. The first column mounting groove 140 and the second column mounting groove 150 are formed on the top of the main wall 110.

[0041] The main wall 110 provides continuous support for the upper components. The herringbone wall 120 extends inwards perpendicular to the main wall 110, effectively adding multiple anti-slip teeth to the base, greatly increasing the contact area and embedment depth between the base and the foundation, effectively resisting the enormous overturning moment and horizontal thrust generated by water pressure. Simultaneously, the protruding reinforcing bars 130 reliably connect to the existing dike structure, ensuring the coordinated operation of the new and old structures and preventing the newly heightened structure from sliding under flood conditions. This structural design solves the engineering challenge of ensuring the stability of the heightened structure while fully utilizing the bearing capacity of the existing dike within a narrow riverside space.

[0042] The fishbone wall 120 is made of C30 reinforced concrete, and the dowel bar 130 consists of two HRB500 threaded steel bars with a diameter of 20mm and a length of 0.9m.

[0043] In actual implementation, the top of the foundation for installing the reinforced concrete base 100, such as the top of the existing gravity flood control wall 900, is first roughened, holes for inserting reinforcing bars are drilled, and reinforcing bars 130 are inserted. The lengths of the reinforcing bars 130 inserted into the main wall 110 and the existing gravity flood control wall 900 are evenly divided. The gaps in the reinforcing bar holes are sealed with Class A adhesive, and asphalt waterproof coating is applied to the joint surface. Then, the construction of the reinforced concrete base 100 is carried out. The main wall 110 and the herringbone wall 120 are made of C30 reinforced concrete and are cast as a whole.

[0044] The flood control wall heightening device also includes diagonal braces 500, which connect the herringbone wall 120 and the first column 210 or the second column 220. By setting diagonal braces 500 between the herringbone wall 120 and the column, a stable triangular support system is constructed. The diagonal braces 500 can directly transfer the enormous water pressure borne by the top of the column to the herringbone wall 120 buried deep in the foundation, thereby significantly reducing the bending moment at the base of the first column 210 and the second column 220 (i.e., the connection point with the base), and optimizing the stress state of the column. This not only allows for a reduction in the cross-sectional dimensions of the column under the same water pressure, reducing material costs, but more importantly, it further enhances the ultimate bearing capacity of the entire flood control wall heightening device against floods exceeding standard levels, providing a higher level of safety. The presence of the diagonal braces 500 also gives the structure better integrity and redundancy when encountering impacts from floating objects.

[0045] The flood control wall heightening device also includes a pedestrian safety component, which includes a guardrail 610, a levee walkway 620, and a footwall 630. The guardrail 610 is placed on top of the main wall 110. The levee walkway 620 is located inside the main wall 110 and connects to the herringbone wall 120, with its top surface flush with the top surface of the main wall 110. The footwall 630 is located inside the levee walkway 620, with its top surface flush with the top surface of the levee walkway 620. By installing the guardrail 610 on top of the main wall 110, pedestrian safety is ensured. Furthermore, because the guardrail is open, it significantly reduces the obstruction of the view of the river by the solid wall, solving the problem of traditional flood control walls that simply block the view and damage the landscape. Aligning the top surface of the embankment walkway 620 with the top surface of the main wall 110 not only provides citizens with a riverside walkway for leisure and sightseeing but also makes the entire embankment space flat and continuous, enhancing the quality of the urban waterfront area. The inner retaining wall 630 serves to define the space and partially retain soil. This design transforms the flood wall from a simple "water barrier" into a composite urban infrastructure integrating flood control, transportation, leisure, and landscaping.

[0046] The guardrail 610 is made of C30 reinforced concrete, while the embankment walkway 620 and the toe wall 630 are made of C25 concrete. The embankment walkway 620 is constructed using compacted gravel.

[0047] In actual implementation, the reinforced concrete base 100 and the foot wall 630 are first poured and constructed. Then, sand and gravel are compacted and filled in layers on the inner side of the main wall 110. Finally, the embankment walkway 620 is poured.

[0048] After construction, the reinforced concrete base 100 can perform flood control tasks throughout the year. Close monitoring of water level changes is necessary. When the flood rises rapidly or a flood forecast issues a warning, the column assembly 200 and multiple baffles 300 must be assembled immediately. During assembly of the column assembly 200 and multiple baffles 300, firstly, the first column 210 and second column 220 are fixed to the top of the main wall 110 using fastening bolts. Then, the baffles 300 are installed between the first column 210, the second column 220, and adjacent second columns 220. Finally, diagonal braces 500 are installed, with both ends fixed to the columns and the herringbone wall 120, respectively.

[0049] The flood control wall heightening device also includes a baffle groove 700 disposed on the top of the reinforced concrete base 100, wherein the baffle 300 may be partially located within the baffle groove 700. Firstly, the baffle groove 700 forms an effective water-stopping path, significantly improving the seepage prevention performance of the contact surface between the baffle 300 and the base 100, preventing floodwater leakage through gaps. Secondly, after the baffle 300 is embedded in the groove, the base 100 provides additional lateral restraint to the baffle 300, enhancing its stability under immense water pressure and preventing horizontal displacement or warping of the bottom of the baffle 300. Furthermore, this embedded connection makes the entire water-blocking structure flatter on the water-facing surface, reducing the impact and scouring of the connection point by the water flow.

[0050] The baffle 300 has spherical protrusions 310 on its water-facing side. When floodwaters or waves impact the baffle 300, these protrusions disrupt the flow pattern, dispersing concentrated linear or planar impact forces into multiple point forces and promoting wave breakage, thereby significantly reducing wave rise and impact pressure. This not only reduces the impact load on the baffle 300 structure itself and extends its service life, but also effectively mitigates the scouring effect of floodwaters on the bottom of the dike. The protruding structure also acts as a buffer during impacts (such as impacts from floating objects), absorbing some of the impact energy and protecting the main structure from damage.

[0051] The flood control wall heightening device also includes a sealing strip 800, which is disposed between the top of the reinforced concrete base 100 and the baffle 300. The sealing strip 800 between the top of the reinforced concrete base 100 and the baffle 300 is a key measure to ensure the overall seepage prevention performance of the flood control wall. The sealing strip 800 effectively fills the tiny gap between the base 100 and the baffle 300, which are made of different materials. When the baffle 300 is subjected to water pressure, the sealing strip 800 is further compressed, forming a reliable dynamic waterstop. This fundamentally solves the potential leakage hazards of prefabricated structures, ensures the absolute airtightness of the flood control wall when blocking water, and protects the safety of the area behind it.

[0052] In this embodiment, the column assembly 200 and the baffle 300 are made of aluminum alloy, the diagonal brace 500 and the baffle sleeve, the bolt sleeve 410 and the baffle groove 700 are made of stainless steel, the fastening bolts are made of hot-dip galvanized high-strength carbon steel, and the sealing strip 800 is made of synthetic rubber.

[0053] In this embodiment, the water-blocking height of the reinforced concrete base 100, column assembly 200, and multiple baffles 300 can be flexibly set. The water-blocking height of the reinforced concrete base 100 can be set to the height of the frequently occurring floods over many years, depending on the hydrological and flood characteristics of the implementation site. For example, if the flood control standard for a certain area is a 50-year flood, but according to flood data from the past 20 years, the frequency of 50-year floods is relatively low, and the scale of frequently occurring floods over many years is mostly at the level of a 20-year flood, then the water-blocking height of the reinforced concrete base 100 can be arranged according to the level of a 20-year flood. Between the height of a 20-year flood and a 50-year flood, the flood control task can be achieved by arranging the column assembly 200 and multiple baffles 300.

[0054] In this embodiment, the structural components included in the column assembly 200 and the multiple baffles 300 are all prefabricated in the factory and installed on site.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
