Abstract
Description
Technical Field
[0001] This utility model relates to the field of gravel dam slope protection technology, and in particular to a gravel dam slope protection device. Background Technology
[0002] Gravel is widely distributed in riverbeds and riverbanks, and its extraction and construction costs are low. After compaction, it has high strength and deformation modulus, making it a good natural material for dam construction. However, due to the discreteness, discontinuity, and easy separation during construction, natural gravel has poor resistance to seepage damage and erosion. Therefore, protective devices are required on the slope of gravel dams.
[0003] While existing slope protection devices can effectively improve the stability of gravel dams to some extent—for example, geonets are often exposed to the external environment, especially under strong ultraviolet radiation, wind, and water flow—they are prone to aging and embrittlement, leading to reduced protective effectiveness and even potential damage or corrosion. Alternatively, concrete and masonry reinforcement requires more building materials and labor, resulting in higher construction and maintenance costs. Therefore, this utility model proposes a gravel dam slope protection device to solve the problems existing in the prior art. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to propose a gravel dam slope protection device. This gravel dam slope protection device has the advantage of effective protection and can solve the problems in the prior art.

[0006] A further improvement is that the positioning element has a cross-shaped cross section and a cavity inside, and the lower part of the positioning element has a through hole, with several groups of through holes evenly distributed.
[0007] A further improvement is that: several sets of installation cavities are formed between the several sets of positioning components and between the positioning components and the first and second embedded components; the reinforcing layer is made of geotextile, and the number and position of the geotextile correspond to the installation cavities; the reinforcing layer is provided with openings, and there are several sets of openings.
[0008] A further improvement is that the inner side of the mounting cavity is also provided with reinforcing ribs, which are composed of transverse steel wires and longitudinal steel wires. Several sets of transverse steel wires and longitudinal steel wires are provided and are arranged in a cross pattern.
[0009] A further improvement is that the cavity is pre-filled with aquaculture soil.
[0010] A further improvement is that the length of the first embedded part is greater than the length of the second embedded part.
[0011] A further improvement is that both the first and second embedded parts have an inner cavity, and the two ends of the inner cavity are connected to the outside.
[0012] The beneficial effects of this utility model are as follows: This gravel dam slope protection device uses a steel wire skeleton as the main body, combined with a reinforcing layer structure of cross-sectional and longitudinal steel wires to ensure the high strength and long-term stability of the entire protection device, which can withstand external stress. Furthermore, the prefabricated turf layer not only provides a superior growth environment for plants, but also effectively resists external erosion, further extending the service life of the slope protection device. At the same time, the device adopts the design of embedded parts and positioning parts, which can be quickly positioned and fixed during construction, reducing the complexity of construction.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0020] according to Figures 1-4 As shown in the figure, this embodiment proposes a slope protection device for a gravel dam, including a steel wire frame. The steel wire frame includes a first embedded part 1, a second embedded part 2, and a positioning part 3. Several sets of the first embedded part 1 and the second embedded part 2 are provided and distributed at both ends of the steel wire frame. Several sets of the positioning part 3 are provided and positioned in the middle of the steel wire frame. The first embedded part 1, the second embedded part 2, and the positioning part 3 are connected by steel wire ropes 4. The length of the first embedded part 1 is greater than the length of the second embedded part 2. Both the first embedded part 1 and the second embedded part 2 have an inner cavity, and both ends of the inner cavity are connected to the outside. Their specific distribution is as follows: Figure 4 As shown, the first embedded part 1 and the second embedded part 2 are used to pre-embed the gravel dam slope, providing the anchoring function of the steel wire skeleton, so that the entire skeleton can be firmly fixed on the gravel dam slope, avoiding displacement or loosening due to external forces (such as water flow, wind, settlement, etc.). Since the slope has a large span and is not in a flat state, a long and a short embedded part are used in combination. The long embedded part provides a longer fixed foundation for the entire structure, while the short embedded part is more suitable for smaller spans or relatively gentle slopes, thus better adapting to changes in the slope span.
[0021] Positioning component 3, located in the middle of the steel wire skeleton, functions to ensure the correct positioning of the entire steel wire skeleton system, enabling precise alignment and stability of all parts. The cross-shaped design of positioning component 3 increases the contact area, enhancing its support for the entire skeleton structure. Furthermore, positioning component 3 has a cross-shaped cross-section and a cavity 7 within it. The lower part of positioning component 3 has through holes 8, evenly distributed in several groups. Cultivation soil is pre-filled within the cavity 7. During use, the cultivation soil can be used to plant vegetation, ensuring successful root development and enhancing the ecological protection capacity of the slope.
[0022] A reinforcing layer 5 is provided on the steel wire skeleton. Several sets of positioning parts 3 are formed between each other and between the positioning parts 3 and the first embedded part 1 and the second embedded part 2. Several sets of installation cavities 9 are formed. The reinforcing layer 5 is made of geotextile, and the number and position of the geotextile correspond to the installation cavities 9. The reinforcing layer 5 is provided with openings, and there are several sets of openings. The geotextile has good tensile strength, corrosion resistance and water permeability. In the protection of dam slope, it can effectively prevent wind erosion of the slope, so as to enhance the protection performance of this device for gravel dam slope. The design of the openings is conducive to the growth of subsequent plant roots.
[0023] A precast turf layer 6 is installed on top of the reinforcing layer 5. Herbaceous plants are planted on the precast turf layer 6. The reinforcing layer 5 also provides some support, ensuring that the precast turf layer 6 is firmly fixed to the slope. The precast turf layer 6 typically consists of grass seeds and a thin layer of soil, effectively providing the environment necessary for plant growth and offering some protection to the gravel dam slope. Furthermore, the roots of the herbaceous plants can penetrate deep into the thin soil layer and the underlying gravel of the gravel dam slope, forming a natural connection between the two and enhancing the stability of the slope structure.
[0024] The inner side of the mounting cavity 9 is also provided with reinforcing ribs, which are composed of transverse steel wires 10 and longitudinal steel wires 11. Several sets of transverse steel wires 10 and longitudinal steel wires 11 are provided and are arranged in a cross pattern. By combining the reinforcing rib structure of the cross transverse and longitudinal steel wires, the high strength and long-term stability of the entire protection device are ensured.
[0025] Therefore, this device adopts a variety of protective measures to form a multi-layered protection system, which can not only improve the slope's resistance to erosion and water flow, but also achieve ecological restoration and ensure the stability of the slope in long-term use.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
