Description

Technical Field

[0001] This invention relates to the field of river management and ecological engineering technology, and more specifically, to a riverbank slope reinforcement structure and construction method. Background Technology

[0002] As an important component of the water system, the management of urban rivers and canals is particularly important. Currently, many polluted or unstable river channels in urban development urgently need remediation. In traditional river channel management projects, due to the generally narrow cross-section of these channels, engineers typically use full-section shotcrete for slope reinforcement. This construction method is often combined with support structures such as soil nails or anchor bolts to enhance the overall stability of the slope. Through the sealing effect of the concrete layer, this technology can effectively prevent soil erosion and slope collapse, achieving a stable riverbank effect in a short period.

[0003] However, this rigid support method also shows obvious limitations in practical applications: on the one hand, the large-scale use of concrete materials leads to high engineering costs; on the other hand, the hardened concrete surface completely blocks the space for vegetation growth, causing the riverbank to lose its natural landscape effect. Summary of the Invention

[0004] This invention provides a riverbank slope reinforcement structure, which can ensure the stability of the riverbank slope reinforcement structure while reducing engineering costs; on the other hand, multiple inverted trapezoidal frames and horizontal connecting beams form a vegetation planting area on both sides of the riverbank slope, effectively greening the riverbank environment and significantly improving the ecological landscape effect of the river.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] An embodiment of the present invention provides a riverbank slope reinforcement structure, comprising multiple inverted trapezoidal frames, horizontal connecting beams, and a base of coarse sand, gravel, and clay.

The riverbed connecting beam is connected to the connection between the frame bottom plate and the frame side wall, and the riverbed connecting beam is connected to the frame bottom plate.

[0012] Optionally, both the top connecting beam and the bottom connecting beam are bent connecting beams.

[0013] Optionally, the horizontal connecting beam further includes a middle connecting beam, which is located between the top connecting beam and the slope toe connecting beam; the middle connecting beam is connected to the side wall of the frame; the number of the middle connecting beams is multiple sets, and the multiple sets of the middle connecting beams are distributed at equal intervals on both sides of the riverbank slope.

[0014] Optionally, the spacing between two adjacent central connecting beams is less than 1.5 m, and the width of the central connecting beam is 0.28 to 0.32 m; the thickness of the top plate of the frame is less than 0.25 m, and the thickness of the bottom plate of the frame is less than 0.3 m.

[0015] Optionally, the riverbank slope reinforcement structure also includes tempered glass, which is correspondingly arranged with the plurality of inverted trapezoidal frames; the top plate of the frame has reserved grooves at both ends, and the two ends of the tempered glass are installed in the reserved grooves.

[0016] This invention also provides a construction method for reinforcing riverbank slopes, which is economical, environmentally friendly, and practical, offering a new solution for river management.

[0017] The construction method for the riverbank slope reinforcement structure includes the following steps:

[0018] S1. Build a front cofferdam at the beginning of the river channel construction section and use water pumps to pump the water from the upstream of the river channel to the downstream of the river channel. Build a rear cofferdam at the end of the construction section.

Combined with the filling of clay layers and the backfilling of coarse sand and gravel at the bottom, on the one hand, the stability of the riverbank slope reinforcement structure can be ensured while reducing engineering costs; on the other hand, the multiple inverted trapezoidal frames and the horizontal connecting beams form a vegetation planting area on both sides of the riverbank slope, effectively greening the riverside environment and significantly improving the ecological landscape effect of the river.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. It should be noted that, unless otherwise specified, features in the embodiments of the present invention can be combined with each other.

[0042] In traditional river management projects, full-section shotcrete is often used for slope reinforcement. The resulting reinforced structure leads to high project costs due to the large-scale use of concrete materials. Furthermore, the hardened concrete surface completely blocks the space for vegetation growth, causing the riverbank to lose its natural landscape effect.

[0043] Please refer to Figures 1 to 4 This application provides a riverbank slope reinforcement structure 10, which can effectively green the riverbank environment and significantly improve the ecological landscape effect of the river while ensuring the stability of the riverbank slope.

[0044] Please refer to Figure 1 , Figure 2 The riverbank slope reinforcement structure 10 includes multiple inverted trapezoidal frames 100, horizontal connecting beams 300, a bottom coarse sand and gravel layer 500, and a clay layer 600. The multiple inverted trapezoidal frames 100 are arranged at equal intervals along the length of the riverbank. Each inverted trapezoidal frame 100 includes a frame base plate 110, two frame side walls 130, and a frame top plate 150. The frame base plate 110 is located on the riverbed, and the two frame side walls 130 are respectively positioned opposite each other on the two sides of the riverbank slope. The bottom ends of the two frame side walls 130 are connected to the two ends of the frame base plate 110. The top of the side wall 130 of the frame is connected to both ends of the top plate 150 of the frame; the horizontal connecting beam 300 extends along the length of the river channel; the horizontal connecting beam 300 connects multiple inverted trapezoidal frames 100 in sequence, and the multiple inverted trapezoidal frames 100 and the horizontal connecting beam 300 form a vegetation planting area 400 on both sides of the river channel slope; the bottom coarse sand and gravel 500 backfill structure is set between two adjacent frame bottom plates 110, and the clay layer 600 fills the bottom of the river channel and the two sides of the river channel slope, and contacts the multiple inverted trapezoidal frames 100 and the horizontal connecting beam 300.

[0045] Multiple inverted trapezoidal frames 100, arranged at equal intervals along the length of the river channel, are sequentially connected by horizontal connecting beams 300. This ensures the stability of the river channel slope reinforcement structure 10 and, moreover, creates vegetation planting areas 400 on both sides of the river channel slope between the multiple inverted trapezoidal frames 100 and the horizontal connecting beams 300, effectively greening the riverbank environment and significantly improving the ecological landscape of the river. A clay layer 600 is located between the outer perimeter of the multiple inverted trapezoidal frames 100 and the horizontal connecting beams 300 and the inner surface of the river channel. The passive earth pressure generated by the filling of the clay layer 600 can balance the water pressure on the frames, thereby reinforcing the structure of the multiple inverted trapezoidal frames 100, the horizontal connecting beams 300, and the river channel, thus enhancing the overall stability of the river channel slope reinforcement structure 10. In addition, the clay layer provides a growth substrate for subsequent slope vegetation, achieving an organic combination of engineering protection and ecological landscape. The bottom coarse sand and gravel 500 is backfilled between two adjacent frame base plates 110. The high permeability of the bottom coarse sand and gravel 500 can quickly drain the groundwater or river seepage water that has seeped into the riverbed, avoiding water pressure damage to the frame base plate 110 structure. At the same time, it prevents the bottom clay layer 600 from being lost due to water erosion or seepage, thereby further enhancing the stability of the riverbank slope reinforcement structure 10.

[0046] Optionally, the inverted trapezoidal frame 100 is a cast-in-place reinforced concrete inverted trapezoidal frame 100, and the horizontal connecting beam 300 is a cast-in-place reinforced concrete horizontal connecting beam 300. The reinforcing bars in the horizontal connecting beam 300 have a first end 301 and a second end 302, and the first end 301 and the second end 302 are respectively connected at an angle to the reinforcing bars in two adjacent inverted trapezoidal frames 100.

[0047] In the design of the reinforcement arrangement of the horizontal connecting beam 300, it should be noted that the reinforcement within the horizontal connecting beam 300 can either partially traverse the reinforcement within two adjacent inverted trapezoidal frames 100, thus forming an angled connection with them; or it can completely penetrate the reinforcement within two adjacent inverted trapezoidal frames 100, thus forming an angled connection with them. Considering the actual limitations on the length of the reinforcement within the horizontal connecting beam 300, to ensure the overall stability of the riverbank slope reinforcement structure 10, special attention should be paid during construction to prioritize the placement of the first end 301 and the second end 302 inside the inverted trapezoidal frame 100, rather than simply placing them in the connection area between two adjacent frames. By extending the first end 301 and the second end 302 deep into the frame, the connection strength between the horizontal connecting beam 300 and the inverted trapezoidal frame 100 can be significantly improved. After subsequent concrete casting, this arrangement ensures that the connection node between the inverted trapezoidal frame 100 and the horizontal connecting beam 300 has higher load-bearing capacity and durability.

[0048] Optionally, the first end 301 is connected to the reinforcing bars in the adjacent inverted trapezoidal frame 100 at a 90° angle, and the second end 302 is connected to the reinforcing bars in the adjacent inverted trapezoidal frame 100 at a 90° angle, forming a cross-shaped cast-in-place grid beam.

[0049] Please refer to Figure 3 The cross-shaped cast-in-place grid beam can significantly improve the integrity of the riverbank slope reinforcement structure 10 and can evenly distribute stress, enabling the frame and connecting beam to work together to effectively resist horizontal loads (such as water flow impact or earthquake action) and vertical uneven settlement (such as buoyancy caused by water flow, local scouring, etc.), ensuring the stability of the structure.

[0050] From a construction perspective, the integrated cast-in-place cross-shaped grid beams reduce joint treatment procedures, improve construction efficiency, and ensure the compactness and durability of the joints. From an economic perspective, the rigid connection between the frame and the horizontal connecting beams 300 forms a spatial grid system, which fully utilizes the mechanical properties of the materials and achieves efficient load transfer. This allows for a reduction in component cross-sectional dimensions and the amount of concrete and steel reinforcement used while ensuring structural safety, making it particularly suitable for large-span applications in river management projects.

[0051] Optionally, the distance between two adjacent inverted trapezoidal frames 100 is less than 1 m, and the width of the inverted trapezoidal frame 100 is less than 0.8 m.

[0052] The factors affecting the stability of the main body of the riverbank slope reinforcement structure 10 (referring to the cast-in-place inverted trapezoidal frames 100 and the cast-in-place horizontal connecting beams 300) mainly include the distance between two adjacent inverted trapezoidal frames 100, the thickness of the cast-in-place inverted trapezoidal frames 100, the distance between the cast-in-place horizontal connecting beams 300, and the thickness of the cast-in-place horizontal connecting beams 300. When the distance between two adjacent inverted trapezoidal frames 100 is less than 1 m and the width of the inverted trapezoidal frames 100 is less than 0.8 m, a balance between the stability and economy of the main body of the riverbank slope reinforcement structure 10 can be achieved. This size control ensures that the horizontal connecting beams 300 between the frames provide sufficient spatial stiffness to resist horizontal loads such as water flow impact and uneven vertical settlement, while avoiding material waste caused by excessive span of the connecting beams or excessive thickness of the frame cross-section due to excessive spacing between the frames.

[0053] Optionally, the horizontal connecting beam 300 includes a top connecting beam 310 and a bottom connecting beam 330. The top connecting beam 310 is located on the riverbank and is connected to the connection between the top plate 150 of the frame and the side wall 130 of the frame.

[0054] The bottom connecting beam 330 is located at the bottom of the river. The bottom connecting beam 330 includes a slope toe connecting beam 331 and a river bottom connecting beam 332. The slope toe connecting beam 331 is set at the slope toe of the two sides of the river channel. The river bottom connecting beam 332 is connected to the connection between the frame base plate 110 and the frame side wall 130. The river bottom connecting beam 332 is connected to the frame base plate 110.

[0055] The top connecting beam 310 is located on the riverbank and connects to the top plate 150 of the frame and the side wall. This connection method can not only effectively restrain the deformation of the top of the frame and enhance the anti-overturning stability, but also form a continuous load-bearing ring on the riverbank top, improving the load transfer path.

[0056] The bottom connecting beam 330 structure adopts a composite design, comprising two key components: the slope toe connecting beam 331 and the riverbed connecting beam 332. The slope toe connecting beam 331 is located at the toe of the slope on both sides of the river channel, serving to stabilize the slope and prevent local erosion; while the riverbed connecting beam 332 forms a stable bottom support network through a double connection method (connected to the bottom plate 110 of the frame and the side wall 130 of the frame).

[0057] The top connecting beam 310 and the bottom connecting beam 330 are indirectly connected through multiple inverted trapezoidal frame structures 100. In some embodiments, vertical connecting beams can also be set to directly connect different types of horizontal connecting beams 300, thereby improving the stability of the main body of the riverbank slope reinforcement structure 10.

[0058] Optionally, both the top connecting beam 310 and the bottom connecting beam 330 are bent connecting beams.

[0059] The bent connecting beam, through its unique geometric shape, firstly significantly enhances the spatial stiffness of the riverbank slope reinforcement structure. Its polygonal structure can more effectively transfer multi-directional loads, especially when resisting the complex hydrodynamic effects generated by river flow (specifically the riverbed), providing three-dimensional constraint on multiple inverted trapezoidal frames 100. Secondly, the bent design greatly improves the mechanical performance of the connection nodes between the horizontal connecting beam 300 and the multiple inverted trapezoidal frames 100. By increasing the connection contact surface, the stress distribution is more uniform, effectively avoiding the stress concentration phenomenon that is prone to occur in traditional straight beam connections. More importantly, the bent structure allows the horizontal connecting beam 300 to better adapt to changes in river topography. The top bent beam can follow the direction of the shoreline, while the bottom bent beam can conform to the undulations of the riverbed, thereby reducing the amount of foundation treatment work while ensuring structural continuity. Finally, this design also brings construction convenience. The bent nodes can serve as natural concrete pouring segment points, ensuring construction quality and improving work efficiency.

[0060] From an economic perspective, bent connecting beams can reduce material usage and optimize project costs compared to straight beam schemes, while achieving the same structural performance.

[0061] Optionally, the horizontal connecting beam 300 also includes a middle connecting beam 320, which is located between the top connecting beam 310 and the slope toe connecting beam 331; the middle connecting beam 320 is connected to the side wall 130 of the frame; there are multiple sets of middle connecting beams 320, and the multiple sets of middle connecting beams 320 are distributed at equal intervals on both sides of the riverbank slope.

[0062] Multiple sets of intermediate connecting beams are formed between the top connecting beam 310 (bank top constraint) and the bottom connecting beam 330 (foundation consolidation). These beams are equidistant and spaced apart, connecting the side walls 130 of the frame into a spatial grid system, which can effectively suppress the lateral bending deformation of the inverted trapezoidal frame 100 under dynamic water pressure. Furthermore, the spaced arrangement of the multiple sets of intermediate connecting beams preserves water exchange space, avoiding the disruptive effect of traditional continuous concrete retaining walls on the riverbank ecology.

[0063] More importantly, through the synergistic effect of the three-dimensional structure of the top-middle-bottom connecting beam 330, a force-bearing mode of "upper anchoring, middle force transmission, and lower stability" is achieved, which reduces the overall cost and extends the service life of the overall riverbank slope reinforcement structure 10.

[0064] Optionally, the spacing between two adjacent intermediate connecting beams 320 is less than 1.5 m, and the width of the intermediate connecting beam 320 is 0.28-0.32 m; the thickness of the top plate 150 of the frame is less than 0.25 m, and the thickness of the bottom plate 110 of the frame is less than 0.3 m.

[0065] By rationally setting the spacing between adjacent intermediate connecting beams 320, the width of the intermediate connecting beams 320, the thickness of the top plate 150 of the frame, and the thickness of the bottom plate 110 of the frame, significant advantages are demonstrated in terms of structural safety and economic rationality. The spacing of the intermediate connecting beams 320 is less than 1.5 m, which ensures structural stability while avoiding excessive obstruction to water flow and maintaining the ecological connectivity of the river channel. The optimized width of the intermediate connecting beams 320 and the thickness of the top plate 150 and bottom plate 110 of the frame can reduce the amount of concrete used, reduce the structural self-weight, and improve economy while meeting the requirements of anti-buoyancy and anti-scour.

[0066] Optionally, the riverbank slope reinforcement structure 10 also includes tempered glass 200, which is correspondingly arranged with multiple inverted trapezoidal frames 100; the top plate 150 of the frame has reserved grooves 151 at both ends, and the two ends of the tempered glass 200 are installed in the reserved grooves 151.

[0067] Please refer to Figure 4By utilizing the existing frame structure, pre-reserved grooves 151 are set at both ends of the top plate 150 of the frame, and tempered glass 200 is installed in the pre-reserved grooves 151, providing a safe, comfortable and scenic place for residents to walk and rest.

[0068] Understandably, during the actual construction process, the tempered glass 200 is embedded in the groove at both ends and can be fixed with elastic sealant to ensure a stable connection and adapt to temperature deformation.

[0069] This invention also provides a construction method for reinforcing riverbank slopes, which is economical, environmentally friendly, and practical, offering a new solution for river management.

[0070] Please refer to Figure 5 The construction method for reinforcing riverbank slopes includes the following steps:

[0071] S1. Build a front cofferdam at the beginning of the river channel construction section and use water pumps to pump the water from the upstream of the river channel to the downstream of the river channel. Build a rear cofferdam at the end of the construction section.

[0072] S2. After removing the silt from the bottom of the river channel and slightly leveling the existing river channel topography, backfill the bottom of the river channel and the river channel slopes on both sides with a layer of clay.

[0073] S3. Arrange and tie the required steel bars for the side walls and bottom plate of multiple inverted trapezoidal frames in sequence along the length of the river channel to form the first steel cage;

[0074] S4. Arrange and tie the required steel bars for the bottom connecting beam and the middle connecting beam between two adjacent first steel cages; connect and tie the first and second ends of the required steel bars for the bottom connecting beam and the middle connecting beam to the required steel bars for the bottom frame and the side wall of the frame at an angle to form the second steel cage.

[0075] S5. Set up the first set of formwork outside the first and second reinforcing cages, fix it and ensure the formwork is sealed;

[0076] S6. Concrete is poured on-site within the first set of formwork to form the base plate, side walls, bottom connecting beam, and middle connecting beam of the frame;

[0077] S7. When the concrete strength reaches 80% of the design strength, arrange and tie the steel bars required for the top plate and top connecting beam of the frame to form the third steel cage, and set up the second set of formwork on the outside of it, fix it and ensure the airtightness of the formwork;

[0078] S8. Concrete is poured on-site within the second set of formwork to form the top slab of the frame and the top connecting beam, thereby forming the inverted trapezoidal frame and the horizontal connecting beam;

[0079] S9. Fill the space between the bottom plates of two adjacent frame structures with coarse sand and gravel, and form a vegetation planting area with the middle connecting beam and the side wall of the frame structure. Plant vegetation in this vegetation planting area.

[0080] S10. Install tempered glass in the reserved groove on the top plate of the frame.

[0081] In summary, the riverbank slope reinforcement structure 10 of this application has the following advantages:

[0082] 1. By using horizontal connecting beams 300 to connect multiple inverted trapezoidal frames 100 arranged at equal intervals along the length of the river channel, on the one hand, it can ensure that the river channel slope reinforcement structure 10 can ensure the stability of the river channel slope; on the other hand, the multiple inverted trapezoidal frames 100 and the horizontal connecting beams 300 form a vegetation planting area 400 on both sides of the river channel slope, effectively greening the riverbank environment and significantly improving the ecological landscape effect of the river channel.

[0083] 2. The clay layer 600 is located between the outer perimeter of the multiple inverted trapezoidal frames 100 and the horizontal connecting beams 300 and the inner surface of the river channel. The passive earth pressure generated by the filling of the clay layer 600 can balance the water pressure on the frames from the river channel, thereby reinforcing the structure of the multiple inverted trapezoidal frames 100, the horizontal connecting beams 300 and the river channel, and thus enhancing the overall stability of the riverbank slope reinforcement structure 10. In addition, the clay layer 600 can provide a growth substrate for subsequent slope vegetation, achieving an organic combination of engineering protection and ecological landscape.

[0084] 3. The bottom coarse sand and gravel 500 backfill structure is set between two adjacent frame base plates 110. The high permeability of the bottom coarse sand and gravel 500 can quickly drain the groundwater or river seepage water that has seeped into the river bottom, avoid water pressure damage to the frame base plate 110 structure, and at the same time prevent the bottom clay layer 600 from being lost due to water flow erosion or seepage, thereby further enhancing the stability of the riverbank slope reinforcement structure 10.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
