Description

Technical Field

[0001] This utility model relates to the field of eco-friendly riverbank slope protection technology, and in particular to eco-friendly riverbank slope protection. Background Technology

[0002] The design and application of eco-friendly riverbank protection slopes must consider both engineering stability and ecological restoration functions. Eco-friendly slope protection includes: plant-based slope protection: soil stabilization through root systems (deep root anchoring, shallow root reinforcement), suitable for gentle riverbanks with slopes ≤12°, commonly using drought-resistant plants such as bermudagrass and tamarisk, with a vegetation survival rate ≥90%, and the impact of water level fluctuations must be considered; geosynthetic composite slope protection: three-dimensional vegetation net + grass planting technology: the net mat has 3-5 times the erosion resistance of traditional turf, and the net must be smoothly integrated with the slope surface during construction; ecological bag slope protection: permeable woven bags filled with planting soil, which integrates with the root system after degradation, suitable for complex terrain; ecological gabion slope protection: metal mesh filled with stones to form a flexible revetment, with a porosity of 30%-40%, suitable for areas with fluctuating water levels or high-velocity river sections.

[0003] However, the drainage channels of existing eco-friendly river embankment slope protection are easily interfered with by waste and other debris, causing drainage blockage and making it impossible to intercept and centrally treat impurities. Furthermore, the structure of the filter frame is not convenient for installation and disassembly, which further affects work efficiency. In addition, the survival rate of vegetation planted on the slope is not high, which affects the protective effect of the slope protection. Utility Model Content

A rock layer is located inside the riverbank slope protection body. A reinforcing layer is attached to the rock layer. Multiple evenly arranged concrete blocks are located at the front end of the riverbank slope protection body. Drainage holes are opened on all four ends of the concrete blocks.

[0006] Furthermore, the positioning component includes a positioning block. The filter frame is inserted into the mounting groove, and at the same time, the positioning block is inserted into the positioning groove, and the snap-fit ​​block is also inserted into the snap-fit ​​groove, for fixing the filter frame to the slope protection body of the river embankment.

[0007] Furthermore, the first filter element includes a first filter screen, and the second filter element includes a second filter screen, with the first and second filter screens arranged in a front-to-back configuration.

[0008] Furthermore, the fasteners include fastening bolts. When the snap-fit ​​block is snapped into the snap-fit ​​groove, the fastening bolts are rotated and engaged to penetrate the threaded through hole, and are also engaged and inserted into the threaded hole, for fixing the filter frame to the slope protection body of the river embankment.

[0009] Furthermore, the drainage channel has a trapezoidal cross-section, with its bottom lower than the lowest point of the soil slope. The drainage holes have a diameter of -cm and are distributed in a matrix.

[0010] Furthermore, the reinforcement layer is made of a mixture of concrete and steel reinforcement, and is attached to the bottom of the rock layer to reinforce the stability of the riverbank revetment.

[0011] Furthermore, the area between the riverbank revetment and the riverbank is filled with permeable soil, and the slope surface is planted with revetment plants with well-developed root systems.

[0012] The beneficial effects of this utility model are:

[0013] This eco-friendly riverbank revetment effectively intercepts debris through a layered filtration design, preventing drainage system blockage. The easily removable and installable filter frame significantly reduces maintenance difficulty. The deep integration of the reinforcement layer and the rock layer enhances the bearing capacity of the revetment foundation, while the ecological design of the soil stabilization layer promotes vegetation growth, achieving soil and water conservation and ecological restoration, and extending the service life of the revetment.
