Description

Technical Field

[0001] This utility model relates to the technical field of riverbank renovation, and in particular to an ecological renovation structure suitable for rigid riverbanks. Background Technology

[0002] In earlier years, rigid structures were commonly used for riverbank protection, providing strong protection against soil erosion and collapse caused by water flow. Concrete revetments, lattice beam revetments, and Renoir revetments were among the most frequently used rigid revetment structures. The choice of revetment structure was typically based on calculated river erosion velocity to meet the required erosion resistance. However, with social development and ecological civilization construction, the concept of "lucid waters and lush mountains are invaluable assets" has been increasingly put into practice. Rivers, as important ecological carriers and resources, have seen their ecological value increasingly recognized.

[0003] In recent years, river management projects have generally considered adopting more ecological embankment designs for protection and renovation on both sides of the river, aiming to ensure that the embankments meet flood control requirements while possessing better ecological and aesthetic qualities. Enhancing river embankments with strong flood control and erosion resistance while also considering ecological aspects is the development direction for embankment renovation and construction.

[0004] Currently, the most common form of ecological transformation of concrete embankments is to completely demolish the existing concrete slope protection and then build a new ecological embankment. This method wastes some of the original structure and does not make good use of it. In addition, for river sections with severe erosion, in order to ensure the stability and safety of the embankment, grid structures or rigid concrete retaining walls are usually used to cope with the erosion. This means that the embankment still cannot effectively balance stability and ecology. Utility Model Content

[0005] The purpose of this utility model is to provide an ecological transformation structure suitable for rigid embankments, so as to alleviate the technical problems in the existing technology of concrete embankment structures, which are wasteful due to the removal of all concrete during the transformation, and also easily cause the embankment to fail to achieve a good balance between stability and ecology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In the first aspect, this utility model provides an ecological transformation structure suitable for hard embankments, including a lattice structure, an anti-erosion structure, a planting structure, and an embankment structure. Both ends of the lattice structure are connected to the embankment structure. The lattice structure is configured as a grid structure and is used for laying along the embankment slope.

[0008] The erosion protection structure is connected to the side of the lattice structure facing away from the embankment slope, and the side of the erosion protection structure facing away from the lattice structure is connected to the planting structure.

[0009] Furthermore, the lattice structure includes a dry-laid rubble section, a lattice slope protection bottom beam, and multiple sets of lattice beam assemblies. The lattice beam assemblies are configured as a grid structure, and the multiple sets of lattice beam assemblies are used to lay on the embankment slope along the first direction.

[0010] The dry-laid stone section is filled in each cell of the lattice beam assembly, and both the dry-laid stone section and the lattice beam assembly are connected to the anti-erosion structure.

[0011] The lattice slope protection bottom beam is connected to the bottom of the plurality of lattice beam components along a first direction, and the lattice slope protection bottom beam is connected to the embankment structure.

[0012] Furthermore, the lattice beam assembly includes a lattice slope protection top beam and multiple lattice beams, wherein the lattice slope protection top beam is connected to the embankment structure along a first direction;

[0013] Multiple lattice beams are configured as grid modules, one end of which is connected to the top beam of the lattice slope protection and the other end is connected to the bottom beam of the lattice slope protection. The dry-laid stone section is provided within the grid formed by the multiple lattice beams.

[0014] Furthermore, the lattice structure also includes asphalt-impregnated fir planks, which are disposed between adjacent lattice beam components along a second direction.

[0015] Furthermore, the anti-erosion structure includes a filter element and a Reno mattress, wherein the filter element is laid on top of the lattice structure;

[0016] The Reynolds pad is disposed on the filter element, and the planting structure is provided on the top of the Reynolds pad.

[0017] Furthermore, the planting structure includes a planting soil layer and a plant layer, wherein the planting soil layer is disposed on the Reno mattress, and the plant layer is planted in the planting soil layer.

[0018] Furthermore, the embankment structure includes a concrete coping, which is distributed along a first direction and connected to the top beam of the lattice slope protection.

[0019] Furthermore, the embankment structure also includes an embankment crest, which is located at one end of the concrete capping away from the top beam of the lattice slope protection.

[0020] Furthermore, the embankment structure also includes an embankment toe revetment, which is distributed along a first direction and connected to the bottom beam of the lattice slope protection, and the embankment toe revetment is connected to the planting structure.

[0021] Furthermore, the embankment structure also includes a toothed wall, which is connected to the side of the embankment toe abutment facing away from the bottom beam of the lattice slope protection.

[0039] Example 1

[0040] This embodiment provides an ecological transformation structure suitable for rigid embankments, referring to... Figure 1 and Figure 2 The ecological transformation structure applicable to hard embankments includes a grid structure 1, an anti-erosion structure, a planting structure, and an embankment structure. Both ends of the grid structure 1 are connected to the embankment structure. The grid structure 1 is designed as a mesh structure and is used to lay along the embankment slope. The anti-erosion structure is connected to the side of the grid structure 1 that is away from the embankment slope, and the side of the anti-erosion structure that is away from the grid structure 1 is connected to the planting structure.

[0041] This utility model embodiment at least alleviates the technical problem in the prior art that the renovation of concrete embankment structures is wasteful due to the removal of all concrete, and also easily leads to the inability to balance stability and ecology of the embankment.

[0042] In this embodiment of the utility model, the embankment structure is set at the top and bottom of the embankment slope, and a grid structure 1 is provided in the area enclosed by the embankment structure. The grid structure 1 is laid on the embankment slope, and an anti-erosion structure and a planting structure are provided on the grid structure 1. Under the premise of having good embankment stability and slope protection functions, the planting of green plants can increase the aesthetic effect and improve the environment. The bottom of the embankment structure extends to the riverbed 10 to support and reinforce the grid structure 1 from the top and bottom.

[0043] Compared with existing technologies, the ecological transformation structure for rigid embankments provided in this embodiment of the utility model satisfies the stability requirements of the embankment by setting a lattice structure 1 on the embankment slope. Furthermore, the lattice structure 1 facilitates the installation of erosion control structures, followed by planting structures, achieving the effect of planting vegetation on the embankment slope. This satisfies the need for both embankment structural stability and ecological improvement. Moreover, the embankment structure retains the top and bottom sections of the existing concrete embankment for reuse, thus avoiding the waste caused by the complete demolition of the existing structure while meeting stability requirements.

[0044] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The lattice structure 1 includes a dry-laid stone section 12, a lattice slope protection bottom beam 14, and multiple sets of lattice beam assemblies. The lattice beam assemblies are designed as a grid structure, and the multiple sets of lattice beam assemblies are used to lay on the embankment slope along a first direction. The dry-laid stone section 12 is filled in each grid of the lattice beam assembly, and both the dry-laid stone section 12 and the lattice beam assembly are connected to the erosion protection structure. The lattice slope protection bottom beam 14 is connected to the bottom of the multiple lattice beam assemblies along the first direction, and the lattice slope protection bottom beam 14 is connected to the embankment structure.

[0045] Specifically: the grid-structured slope protection bottom beam 14 is distributed along a first direction and connected to the embankment structure. The first direction is preferably transverse. The grid-structured slope protection bottom beam 14 is laid at the bottom of the embankment slope. Multiple sets of grid beam components are connected to the grid-structured slope protection bottom beam 14 along the extension direction of the grid-structured slope protection bottom beam 14 and are set on the embankment slope. Each grid of the grid beam component is filled with dry-laid stone blocks 12 to make the grid beam component more stable.

[0046] Furthermore, referring to Figure 1 and Figure 2 The lattice beam assembly includes a lattice slope protection top beam 11 and multiple lattice beams 13. The lattice slope protection top beam 11 is connected to the embankment structure along a first direction. The multiple lattice beams 13 are configured as grid modules. One end of the grid module is connected to the lattice slope protection top beam 11, and the other end is connected to the lattice slope protection bottom beam 14. The grid formed by the multiple lattice beams 13 is provided with dry-laid stone blocks 12.

[0047] Specifically: the grid-structured top beam 11 is distributed along the first direction, and multiple grid beams 13 are intersected and connected at intervals along the first and second directions to form a grid structure; the top and bottom of the grid module are connected to the grid-structured top beam 11 and the grid-structured bottom beam 14, so that the grid module is set on the embankment slope, and the dry-laid rubble section 12 is filled in each grid of the grid module.

[0048] Furthermore, referring to Figure 2 The lattice structure 1 also includes asphalt fir planks 15, which are disposed between adjacent lattice beam components along the second direction.

[0049] Specifically: Expansion joints are provided between the lattice beam components, and asphalt cedar planks 15 can be installed in these expansion joints. The asphalt cedar planks 15 are installed between lattice beam components of a certain length to divide the longer lattice structure 1, which to a certain extent avoids the deformation of the concrete lattice structure 1 due to factors such as thermal expansion and contraction, and ensures the safety and stability of the structure.

[0050] It should be emphasized that the first direction can be perpendicular to the second direction, so that the lower layer of the lattice structure 1 presents a cross-shaped grid structure; and the lower layer of the lattice structure 1 can also be a rhomboid structure or other concrete and reinforced concrete skeleton slope protection reinforcement forms.

[0051] In an optional implementation of this embodiment, refer to Figure 1 The anti-scouring structure includes a filter element 2 and a Reno mattress 3. The filter element 2 is laid on top of the lattice structure 1. The Reno mattress 3 is set on the filter element 2, and a planting structure is provided on the top of the Reno mattress 3.

[0052] Specifically: The Reno mattress 3 is installed on the lattice structure 1 along its extension direction, and a filter element 2 is provided between the Reno mattress 3 and the lattice structure 1. The Reno mattress 3 can be filled with materials such as boulders to serve as an anti-erosion structure for embankments. The Reno mattress 3 has the advantages of flexibility and adaptability to the foundation. The filter element 2 has a filtering function.

[0053] It should be emphasized that the erosion protection structure may also include eco-concrete, with a certain thickness of eco-concrete used to cover the top of the lattice structure 1, in order to replace the Reno mattress 3.

[0054] The filter element 2 can be geotextile or other filter materials, which allows water to pass through but not soil.

[0055] Furthermore, referring to Figure 1 The planting structure includes a planting soil layer 4 and a plant layer 5. The planting soil layer 4 is placed on the Reno mattress 3, and the planting soil layer 4 is planted with the plant layer 5.

[0056] Specifically: the planting soil layer 4 is laid on the Reno mattress 3, and the top of the planting soil layer 4 can be connected to the top of the embankment structure, while the bottom of the planting soil layer 4 is connected to the bottom of the embankment structure; the planting soil layer 4 can be used to plant the plant layer 5, which can be either terrestrial or aquatic plants. If the plant layer 5 is damaged due to excessive water flow during use, structural restoration can be achieved by restoring both the planting soil layer 4 and the plant layer 5, at a relatively low cost.

[0057] In an optional implementation of this embodiment, refer to Figure 1 The embankment structure includes a concrete capping 6, which is distributed along the first direction and connected to the top beam 11 of the grid slope protection.

[0058] Specifically: the concrete capping 6 abuts against the top beam 11 of the grid slope protection, and the concrete capping 6 is set at the top of the embankment slope to achieve the limitation and fixation of the grid structure 1 from above.

[0059] Furthermore, referring to Figure 1 The embankment structure also includes the embankment top 7, which is located at one end of the concrete capping 6 away from the top beam 11 of the grid slope protection.

[0060] Specifically: 7 is laid on the top of the embankment, and refers to... Figure 3 The top of the embankment 7 is the original structure of the embankment, which is connected to the planting soil layer 4. One end of the top of the embankment 7 is pressed on the top of the concrete capping 6 to make the modified embankment more stable.

[0061] In an optional implementation of this embodiment, refer to Figure 1 The embankment structure also includes a toe revetment 8, which is distributed along the first direction and connected to the bottom beam 14 of the grid slope protection, and the toe revetment 8 is connected to the planting structure.

[0062] Specifically: refer to Figure 3 The toe revetment 8 is the original structure of the embankment, and the toe revetment 8 is laid in the river. It is mainly used to support the planting soil layer 4 and abut against the bottom beam 14 of the grid slope protection, so as to support and protect the grid structure 1 from the bottom.

[0063] Furthermore, referring to Figure 1 The embankment structure also includes a toothed wall 9, which is connected to the side of the embankment toe abutment 8 away from the bottom beam 14 of the grid slope protection.

[0064] Specifically: refer to Figure 3 The toothed wall 9 is the original structure of the embankment, and the toothed wall 9 is inserted vertically into the riverbed 10. One side of the toothed wall 9 abuts against the embankment toe abutment 8, thereby further supporting the embankment toe abutment 8 and the structure above it.

[0065] Reference Figure 3During construction, after the concrete slope protection 101 is removed, the embankment structure, lattice structure 1, erosion prevention structure and planting structure can be set in sequence to realize the embankment renovation construction, so that the embankment meets the needs of reinforcement and ecological improvement after renovation.

[0066] It should be noted that after the concrete slope protection 101 is removed, the combination of the grid structure 1 and the anti-scour structure can meet the requirements for the stability and safety of the embankment. Furthermore, the planting structure set on its upper part allows the roots of the planted plants to extend into the gaps between the stones of the Reno mattress 3, which is more conducive to the survival of the plants.

[0067] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. The above embodiments in this specification are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model.
