Description

Technical Field

[0001] This application relates to the technical field of ecological revetment engineering, and in particular to an ecological block revetment block structure and its construction method. Background Technology

[0002] Ecological bank protection refers to a type of riverbank protection that, in addition to preventing riverbank collapse, allows for the interpenetration of river water and soil, enhancing the river's self-purification capacity and providing a certain degree of natural landscape effect. It utilizes vegetation or a combination of vegetation and civil engineering to protect riverbank slopes. Ecological bank protection integrates flood control, ecological, landscape, and self-purification effects, representing a significant advancement in bank protection engineering and poised to become the mainstream approach in future projects.

[0003] Related technologies include an ecological block revetment structure disclosed in Chinese Patent No. CN112575742B, which includes a block body comprising an inner frame and an outer frame. The inner frame and the outer frame are fixedly connected by reinforcing rods. Connecting ends are provided on all four side walls of the outer frame, and the four connecting ends are evenly distributed circumferentially. The construction method of this invention includes the following steps: 1) construction preparation; 2) base treatment; 3) construction of the ecological block revetment.

[0004] In the aforementioned related technologies, the applicant discovered that in the implementation of the above-mentioned ecological block revetment structure, any two adjacent blocks are relatively fixedly connected. When the blocks are spliced ​​together, the surface of the resulting ecological block revetment is flat. However, if the riverbank slope experiences localized soil detachment and a depression occurs, there may be a void between the ecological block revetment and the depression on the riverbank slope. This would prevent the blocks installed on the depression from receiving effective support, resulting in insufficient installation stability of the blocks. Therefore, the existing ecological block revetment has very high requirements for the surface flatness of the riverbank slope, which increases the difficulty of riverbank slope surface treatment and thus needs improvement. Summary of the Invention

[0005] The purpose of this application is to provide an ecological block revetment structure and its construction method, which is suitable for uneven riverbank slopes and can also increase the surface area of ​​the riverbank slope.

[0006] Firstly, this application provides an ecological block revetment structure, employing the following technical solution:

[0007] An ecological block revetment structure includes a block body, each block body having a cone at its center, the axis of the cone being perpendicular to the surface of the block body, and a connector being provided between any two adjacent block bodies, the connector being detachably connected to the block body; when the block body is installed on the riverbank slope, the cone is inserted into the riverbank slope, and the block body fits against the riverbank slope.

[0008] Specifically, by setting cones on the block body, the middle part of the block body can be inserted into the riverbank slope. When the block body needs to be installed on the concave part of the riverbank slope, the block body can achieve a relatively fixed connection with the riverbank slope through the cones. Furthermore, the periphery of the block body can be fixedly connected with other block bodies through connectors, effectively ensuring the installation stability of the block body in the concave part.

[0009] Furthermore, the block includes a connecting part, an arc-shaped component, and a grid block plate. The connecting part is integrally connected to the cone. Several arc-shaped components are arranged around the periphery of the connecting part. One end of each arc-shaped component is integrally connected to the connecting part, and the other end of each arc-shaped component is bent towards the direction close to the riverbank slope. The cone passes through the middle of the grid block plate, and the cone and the grid block plate can be fixedly connected.

[0010] Specifically, the holes in the grating block slab can be used for plant growth. The grating block slab fits into the riverbank slope and is connected to each arc-shaped component by the connecting part that connects to the cone. This allows the height between the grating block slab and the connecting part to be adjusted, so that the grating block slab can always fit into the riverbank slope, which is conducive to plant growth. The end of the arc-shaped component away from the connecting part can also be inserted into the riverbank slope, which can play a multi-point support role.

[0011] Furthermore, an elastic rubber ring is fixed inside the grid block plate, the cone passes through the elastic rubber ring, and the outer wall of the cone is interference-fitted with the elastic rubber ring. Several cuts are provided on the inner wall of the elastic rubber ring, and each cut is equidistantly arranged around the axis of the elastic rubber ring.

[0012] Specifically, the elastic rubber ring ensures the friction between the grating block and the cone, allowing the grating block to maintain a stable connection with the cone. The cut allows the elastic rubber ring to generate a larger amount of deformation, enabling the grating block to maintain a stable connection with the cone whose cross-sectional area varies with the length.

[0013] Furthermore, the grid block panel includes several perforated panels, each of which is equidistantly arranged around the axis of the elastic rubber ring. Each perforated panel is fixedly connected to the outer wall of the elastic rubber ring. An movable gap is reserved between any two adjacent perforated panels, and several metal pieces are arranged along the length of each movable gap within each movable gap. Both ends of each metal piece are fixedly connected to the perforated panels located on both sides of the movable gap.

[0014] Specifically, two adjacent grid blocks are connected by metal sheets, allowing the angle between the two adjacent grid plates to be adjusted, so that the grid block plates can fit tightly to the concave and convex parts of the riverbank slope.

[0015] Furthermore, each of the arc-shaped components is provided with a connecting seat at the end away from the connecting part. The connecting seat is located on the side of the arc-shaped component away from the cone. Each connecting seat is provided with a connecting groove. When any two adjacent block bodies are spliced ​​together, each of the two block bodies has a connecting seat that fits into each other, so that the two closely spaced connecting grooves can form a limiting groove with a cross-section of "8". The connecting component is set as a connecting block with a cross-section of "8". The connecting block can be embedded in the limiting groove formed by the two block bodies.

[0016] Specifically, by utilizing the cooperation between the connecting block and the limiting groove formed by the enclosing of the two block bodies, the connecting block can connect the arc-shaped parts of the two block bodies together, thereby achieving the effect of connecting the two block bodies together using the connecting block.

[0017] Furthermore, it also includes several grid meshes, with multiple adjacent blocks arranged in a ring around the perimeter of the grid meshes. The cones of each block block pass through the edge of the grid mesh, and each grid mesh is attached to the side of the grid block slab closest to the riverbank slope. Each grid mesh is woven from elastic ropes, and the grid meshes are in a taut state when connected to each block block.

[0018] Specifically, the use of grid mesh can further protect the riverbank slope, and the grid mesh can also connect the various cones together. The combination of multiple grid meshes can further ensure the connection stability between the various blocks.

[0019] Secondly, this application provides a construction method based on the ecological block revetment block structure described above, employing the following technical solution:

[0020] A construction method for an ecological block revetment structure includes the following steps:

[0021] 1) Construction preparation: Survey and clear the construction site, and conduct surveying and setting out;

[0022] 2) Base treatment: Clean the surface soil layer of the riverbank slope, and remove a soil layer with a thickness of 10-15 cm;

[0023] 3) Sowing and maintenance: Backfill a layer of plain soil 2-3cm thick on the surface of the riverbank slope, sow seeds on the plain soil layer, and spray water for maintenance. The maintenance period is 14 days.

[0024] 4) Ecological block construction: Each block body is installed sequentially on the riverbank, and any two adjacent blocks are connected by connectors;

[0025] 5) Adjust the angle of each grid block so that each grid block can fit against the riverbank slope.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The block body has two relatively movable parts, one of which protects the riverbank slope, and the other serves as support and connection, making the block body suitable for uneven riverbank slopes.

[0028] 2. The arched design of the block body not only serves as a support for the riverbank slope, but also increases the surface area of ​​the riverbank slope, thus buffering the river water.

[0029] 3. When the block body is connected to the riverbank slope, it can be set up in a cage shape, so that water birds and animals living along the river can use it for nesting. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0038] An ecological block revetment structure, referring to Figure 1 The system includes a block body 1, a grid mesh 2, and connectors 3. The grid mesh 2 consists of several sheets, and each sheet has several block bodies 1 arranged on its periphery. Any two adjacent block bodies 1 are connected by connectors 3. When the block bodies 1 and grid mesh 2 are installed on a riverbank slope, the grid mesh 2 is laid on the slope and secured by the block bodies 1.

[0039] It should be noted that the block body 1 located between two arbitrarily set grid meshes 2 is simultaneously fixedly connected to the two block bodies 1 mentioned above.

[0040] Reference Figure 2 and Figure 3 The block body 1 includes a fixing part 12 and a grid block plate 11, with the grid block plate 11 installed inside the fixing part 12. When the block body 1 is installed on the riverbank slope, the grid block plate 11 fits against the riverbank slope, the middle part of the fixing part 12 is fixed to the riverbank slope, and the edge of the fixing part 12 is selectively connected to the riverbank slope.

[0041] Reference Figure 2 and Figure 4 The grid block panel 11 includes a perforated panel 111, metal sheets 112, and an elastic rubber ring 113. The perforated panel 111 comprises several pieces, each circumferentially arranged around the axis of the elastic rubber ring 113 at equal intervals. Each perforated panel 111 is fixedly connected to the outer wall of the elastic rubber ring 113, with a pre-existing gap between any two adjacent perforated panels 111. The metal sheets 112 comprise several pieces, each evenly distributed within a specific gap. Each metal sheet 112 contains several metal sheets arranged along the length of the gap, and both ends of each metal sheet 112 are fixedly connected to the perforated panels 111 located on either side of the gap.

[0042] Among them, a planting trough is provided on the hollow masonry plate 111, which is used for plant planting and production. Several cuts are provided on the inner wall of the elastic rubber ring 113, and each cut is arranged equidistantly around the axis of the elastic rubber ring 113.

[0043] Reference Figure 3 and Figure 5 The fixing part 12 includes a cone 121, a connecting part 122, an arc-shaped member 123, and a connecting seat. The cone 121 and the connecting part 122 are arranged coaxially. One end of the cone 121 is fixedly connected to the side of the connecting part 122 facing the riverbank slope. The other end of the cone 121 is set as a pointed end. Several arc-shaped members 123 are arranged around the periphery of the connecting part 122. One end of each arc-shaped member 123 is connected to the connecting part 122, and the other end of each arc-shaped member 123 is bent towards the direction close to the riverbank slope. Several connecting seats are provided. Each connecting seat is respectively located on the end of each arc-shaped member 123 away from the connecting part 122, and each connecting seat is located on the side of the arc-shaped member 123 away from the cone 121.

[0044] The cone 121 passes through the elastic rubber ring 113 on the grid block plate 11, and the cone 121 and the outer wall of the elastic rubber ring 113 are interference-fitted.

[0045] When the block body 1 is installed on the riverbank slope, the cone 121 is inserted into the riverbank slope, and the grid block plate 11 is in contact with the riverbank slope.

[0046] Reference Figure 6 Each connecting seat is provided with a connecting groove. When any two adjacent block bodies 1 are spliced ​​together, each of the two block bodies 1 has a connecting seat that fits into each other, so that the two connecting grooves that are close to each other can form a limiting groove with a cross-section of "8". The connecting piece 3 is set as a connecting block with a cross-section of "8", and the connecting block can be embedded in the limiting groove formed by the two block bodies 1.

[0047] When the block body 1 is connected to the grid mesh 2, the cone 121 of the block body 1 passes through the edge of the grid mesh 2. Each grid mesh 2 is woven from elastic rope. When the grid mesh 2 is connected to each block body 1, the grid mesh 2 is in a taut state.

[0048] The working principle of this application embodiment:

[0049] By setting a cone 121 on the block body 1, the middle part of the block body 1 can be inserted into the riverbank slope by inserting the cone 121. When the block body 1 needs to be installed on the concave part of the riverbank slope, the block body 1 can achieve a relatively fixed connection with the riverbank slope through the cone 121. The periphery of the block body 1 can be fixedly connected with other block bodies 1 through the connector 3, effectively ensuring the installation stability of the block body 1 in the concave part.
