Description

Technical Field

[0001] The utility model relates to the technical field of ecological slope protection, and more specifically to an ecological building block for protecting river bank slopes. Background Art

[0002] The riverbank ecological slope protection structure is a riverbank protection measure that combines ecological principles and engineering technology. It not only effectively prevents riverbank erosion, but also improves the self-purification capacity of the river channel and beautifies the riverbank landscape by promoting mutual penetration of water and soil. It uses plants or combines with civil engineering to protect the river channel slope, marking an important progress in modern river management and leading the mainstream direction of future riverbank protection. Its core concept is to use plant roots and engineering measures to enhance the stability and anti-scouring ability of the river bank, such as planting local plants to strengthen the soil and combining ecological blocks to improve the overall protection effect. At the same time, it focuses on the combination of landscape and ecological effects to create a riverbank environment with both aesthetic and ecological values.

[0003] The existing riverbank ecological slope protection structure still faces some challenges in practical application, such as low structural strength and anti-scouring ability of ecological blocks, high technical requirements during construction, high maintenance costs in the later stage, and limited living space for vegetation and organisms. In response to these problems, it is necessary to further optimize the design scheme, improve the construction technology level, promote advanced ecological slope protection materials and technologies, and promote the continuous improvement and development of riverbank ecological slope protection structures.

[0007] The structures of the block body are integrally cast by ecological concrete at one time, which not only ensures the environmental protection of the block, but also increases the overall rigidity of the block. Several block bodies are interlocked and spliced ​​with each other through the limiting holes of the capping structure 1 and the connecting blocks 4. During installation, the block body is laid flat along the slope in an inclined shape, and the wedge-shaped body 32 of the embedded structure 3 is inserted into the soil perpendicular to the slope.

[0008] Furthermore, during the integral casting process, bamboo bars are embedded in the concrete to increase toughness.

[0009] Furthermore, the specific structures of each component are as follows:

[0010] The capping structure 1 comprises a capping anti-skid groove 11, limiting holes 12, 13 and a capping block 14; the back of the capping block 14 is provided with an anti-skid groove 11, and both ends of the capping structure 1 are provided with a left limiting hole 12 and a right limiting hole 13, and the limiting holes are used for interlocking connection between adjacent block bodies;

The interior of the frame body 22 is a hollow structure. The hollow part is used for planting vegetation, so that the roots of the vegetation can be fixed on the slope surface.

[0012] The embedded structure 3 includes a base 31 and a wedge 32. The base 31 is fixedly connected to the bottom of the frame body 22, and the wedge 32 is embedded in the soil layer of the slope 6; that is, one end of the embedded structure 3 is connected to the block body, and the other end is embedded in the slope body, which is used to fix the block body on the slope surface.

It is used to be engaged with the limiting holes 12 and 13 of the top structure 1 of the adjacent block body. That is, the connecting block cooperates with the limiting holes to fix the adjacent block body structure.

[0014] The vegetation trough structure 5 includes an energy dissipation hole 51, a water-permeable hole 52, an ecological hole 53 and a vegetation trough 54. The vegetation trough structure 5 is provided with a hollow cavity inside, energy dissipation holes 51 are provided on both side walls, ecological holes 53 are provided on the front wall, and water-permeable holes 52 are provided on the bottom wall. Specifically: the vegetation trough 54 is provided with a hollow cavity inside, and the vegetation trough 54 is used for vegetation growth and biological habitat; the vegetation trough 54 is provided with energy dissipation holes 51 perpendicular to the side wall of the bank slope 6 to reduce the impact of water flow; water-permeable holes 52 are provided parallel to the bottom of the bank slope 6 to discharge accumulated water; ecological holes 53 are provided parallel to the side wall of the bank slope 6 for biological habitat and reproduction;

That is, the left limiting hole 12 and the right limiting hole 13 and the connecting block 4 are both trapezoidal, and the two can be embedded and connected.

[0016] Furthermore, the top-pressing anti-skid groove 11 and the frame anti-skid groove 21 are both triangular teeth inclined to the bottom of the slope and are equidistantly distributed. The top-pressing anti-skid groove 11 attaches the block to the soil along the slope, and the frame anti-skid groove 21 contacts the slope to increase its anti-skid property. The top-pressing anti-skid groove 11 and the frame anti-skid groove 21 are both provided with a top-pressing structure and a frame structure attached to one side of the slope to increase the friction between the block body and the slope.

[0017] Furthermore, the wedge-shaped body 32 is inserted into the soil perpendicular to the slope surface, so that the block body can be fixed on the slope surface.

[0018] Furthermore, in the vegetation trough structure 5, the energy dissipation holes 51 are prism-shaped and are distributed at equal intervals; the water-permeable holes 52 are all prism-shaped and are distributed at equal intervals; the ecological holes 53 are rectangular and can be used for the exchange between organisms and soil substances, and for the exchange of substances between in-river organisms and bank slopes.

[0019] Furthermore, the diameter of the energy dissipation hole 51 is larger on the inside and smaller on the outside, that is, the side length of the outer side 511 of the energy dissipation hole 51 is larger than the inner side 512 of the energy dissipation hole, which can effectively reduce the impact speed of the water flow; the diameter of the water permeable hole is larger on the inside and smaller on the outside, that is, the side length of the outer side 521 of the water permeable hole 52 is larger than the inner side 522 of the water permeable hole, which can effectively penetrate the accumulated water.

[0020] The design method of an ecological block structure for protecting a river bank slope as described above includes the following steps:

[0021] The vegetation trough structure 5 is designed as a hollow inverted terrace, with upper and lower adjacent building blocks arranged in a staggered manner, providing a larger greening space and lighting space.

[0022] The energy dissipation hole 51 is designed to be stepped according to the Bernoulli principle. The outer diameter of the energy dissipation hole is small and the inner diameter is large, which can effectively slow down the impact speed of the water flow.

[0023] One end of the fixing seat and the base is embedded in the soil, and the other end is used to fix the ecological building block structure. The fixing seat and the building block body are also embedded through a connecting block.

[0024] The beneficial effects of the utility model are:

[0025] The utility model provides an ecological block for protecting river bank slopes and a design method thereof. The block can be laid flat on the river bank slope by mutual embedding and penetration and insertion. The ecological concrete integral casting molding not only ensures its environmental protection, but also increases its overall rigidity by embedding bamboo bars. The hollow frame structure and the vegetation trough structure allow vegetation and organisms to grow and reproduce, which not only increases its protective effect, but also greatly increases its ecology and landscape. In addition, the energy dissipation holes can effectively reduce the impact effect of the water flow, further increasing the protective effect of the slope. BRIEF DESCRIPTION OF THE DRAWINGS
