Abstract
Description
Technical Field
[0001] This invention relates to the field of hydropower station slope protection technology, specifically to a hydropower station dam abutment steep slope protection device. Background Technology
[0002] Protecting the steep slopes of hydropower dam abutments is a crucial aspect of ensuring the structural safety of the dam. Comprehensive measures must be taken, addressing factors such as rock mass stability, seepage pressure, and seismic dynamics. To prevent soil erosion, a common practice is to construct protective devices for the steep slopes of hydropower dam abutments along rivers. This refers to various paving and planting work done on the slope surface to prevent erosion. In river sections where bridges are located, the concave banks are subject to annual erosion, leading to continuous bank collapse. To protect the bridges and embankments, protective structures must be built on the concave banks. Furthermore, when bridge construction alters the river's flow direction, eroding the riverbanks and endangering farmland and villages, protective structures must also be constructed. Hydraulic slope protection plays a role in soil and water conservation and flood control. For aesthetic and environmental greening purposes, turf is often planted on the surface of hydraulic slope protection.
[0003] In the process of realizing this invention, the inventors discovered the following problems with the existing technology: In the existing slope protection of steep slopes at the dam shoulders of hydropower stations, there is no three-dimensional drainage network on the slope protection, and secondly, the fixation of the slope protection is insufficient. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-3This invention provides a technical solution: a slope protection device for steep slopes at the abutment of a hydropower station dam, comprising a slope protection body 1, an inclined surface 2 on one side of the slope protection body 1, a drainage mechanism within the inclined surface 2, the drainage mechanism including a drainage pipe 10 installed within the slope protection body 1, two pairs of grooves 8 within the inclined surface 2, both pairs of grooves 8 communicating with the drainage pipe 10, a filter screen 9 within each pair of grooves 8, two pairs of one-way valves 11 within the drainage pipe 10, a water outlet 6 at the lower end of the wall of the inclined surface 2 communicating with the drainage pipe 10, two pairs of fixing buckles 3 at the upper end of the inclined surface 2, each pair of fixing buckles 3 being connected to a protective net 4, a pair of fixing nails 5 at the lower end of each pair of protective nets 4, and both pairs of fixing nails 5 being fixed to the inclined surface 2.
[0019] Furthermore, the slope protection body 1 includes a gravel layer 14, a soil layer 13 on the sidewall of the gravel layer 14, and a greening layer 12 on the sidewall of the soil layer 13. The greening layer enhances environmental protection.
[0020] Furthermore, the side wall of the slope protection body 1 is provided with a square groove, and the other side wall of the slope protection body 1 is provided with a square insert. The stability can be increased by connecting multiple devices through the square grooves and square inserts.
[0021] Furthermore, each of the protective nets 4 is provided with several long nails, which are fixedly inserted into the gravel layer 14. The long nails can increase the stability of the slope.
[0022] Furthermore, two pairs of handles 7 are provided on the inclined surface 2. People can walk easily by holding the handles.
[0023] Furthermore, the bottom surfaces of both pairs of grooves 8 are provided with anti-slip plates 15. This facilitates walking, increases friction, and prevents slipping.
[0024] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0025] Example: 1. Slope protection structure design and drainage function
[0026] This embodiment of the eco-friendly water conservancy slope protection includes a slope protection body 1, with an inclined surface 2 on one side to adapt to the natural slope. The inclined surface 2 has an embedded drainage mechanism consisting of a drainage pipe 10, two pairs of grooves 8, and a filter screen 9. The grooves 8 are connected to the drainage pipe 10, and their surfaces are covered with the filter screen 9 to intercept sediment. A one-way valve 11 is installed inside the drainage pipe 10 to prevent backflow. During rainfall, water flows through the grooves 8 for filtration and is discharged from the lower outlet 6 through the drainage pipe 10, effectively reducing soil erosion.
[0027] 2. Greening and Ecological Reinforcement
[0028] The slope protection structure 1 adopts a layered structure: the inner layer is a gravel layer 14 to enhance permeability, the middle layer is a soil layer 13 to provide a base for plant growth, and the top layer is a greening layer 12 planted with water-resistant grass species, such as bermudagrass or reeds, to further stabilize the soil. The protective net 4 is anchored to the inclined surface 2 by fixing buckles 3 and fixing nails 5, and its internal long nails are inserted into the gravel layer 14 to enhance the overall erosion resistance.
[0029] 3. Modular installation and anti-slip design
[0030] The slope protection body 1 has square grooves and square blocks on its sidewalls, which can be spliced into multiple modules and is suitable for riverbanks or embankments of different lengths. The bottom of the groove 8 on the inclined surface 2 is equipped with anti-slip plates 15 and handles 7 to facilitate safe walking for construction or maintenance personnel.
[0031] 4. Practical Application Scenarios
[0032] This slope protection system is used in hydropower station projects. During the rainy season, the drainage system efficiently diverts runoff, and the vegetation coverage of the green layer 12 increases to 90%, reducing sediment loss by approximately 40% compared to traditional concrete slope protection. The modular design improves installation efficiency by 30%, and the protective net 4 effectively prevents localized slope collapse.
