Description

Technical Field

[0001] This utility model relates to the field of hydraulic slope protection technology, specifically a slope protection method for hydraulic engineering construction. Background Technology

[0002] Slope protection is crucial for water conservancy projects. Landslides and collapses on slopes can easily cause casualties and property damage, and reasonable protective measures can effectively reduce these risks. At the same time, it can prevent construction stoppages due to landslides and collapses, ensuring the progress of water conservancy projects. Furthermore, it can reduce soil erosion and protect the ecological environment.

[0003] Existing protection methods generally involve dry-laid stone slope protection or concrete slope protection. These methods have a long construction time and require a lot of manpower and resources. In addition, since the slopes that need to be protected are usually newly excavated soil layers that have not undergone long-term settlement, their stability is often relatively poor. Because their soil structure is relatively loose, dry-laid stone slope protection or concrete slope protection is prone to instability and is more likely to cause danger. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection method for water conservancy engineering construction, in order to solve the problem mentioned in the background art that the slopes that need to be protected are generally newly excavated soil layers that have not undergone long-term settlement, and their stability is often relatively poor. Because their soil structure is relatively loose, it is easy to cause instability in dry masonry slope protection or concrete slope protection, and it is more likely to cause danger.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope protection mechanism for water conservancy engineering construction, comprising a slope, a protective dam, and a slope protection structure; the protective dam is constructed at the bottom of the slope, and the slope protection structure covers the upper side of the slope; the slope protection structure consists of a protective blanket, a first fixing mechanism, and a second fixing mechanism; the second fixing mechanism is installed on both longitudinal sides of the protective blanket and at the bends of the protective blanket; the first fixing mechanism is fixed at the inclined position of the protective blanket; the protective blanket consists of a planting blanket and a protective net, and the planting blanket is compositely pasted to the bottom of the protective net.

[0006] Preferably, the protective net is configured as either a polybutylene succinate protective net or a polylactic acid-glycolic acid copolymer protective net.

[0007] Preferably, the protective dam is composed of a concrete wall and reinforcing bars. The concrete wall is poured at the lower part of the slope, and one end of the reinforcing bar extends into the interior of the concrete wall, while the other end of the reinforcing bar extends into the interior of the slope.

[0008] Preferably, the planting blanket is composed of a biodegradable film and plant seeds, with the biodegradable film covering the outer part of the plant seeds.

[0009] Preferably, the biodegradable membrane is one of a starch-based biodegradable membrane, a cellulose membrane, or a polylactic acid membrane.

[0010] Preferably, the first fixing mechanism consists of a limiting plate and a first ground cone, the upper end of the first ground cone is welded to the bottom end of the limiting plate, and the first ground cone passes through the protective blanket and inserts into the soil layer.

[0011] Preferably, the second fixing mechanism consists of a pressure plate and a second ground cone. The second ground cone is evenly installed at the bottom of the pressure plate and penetrates the protective blanket into the soil layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The modular slope protection structure has a clear division of labor. The slope settlement will not be affected by the slope protection structure. The protective blanket provides comprehensive coverage and protection, and the fixing mechanism ensures its stability. It effectively prevents soil loss on the slope, protects the slope stability, and reduces the possibility of geological disasters such as landslides. Over time, the seeds inside the planting blanket will germinate and form a protective lawn or grow into woody plants, which will provide long-term protection to the slope through the roots of the plants.

[0014] 2. The concrete wall has high strength and impact resistance. When poured at the bottom of the slope, it forms a barrier. One end of the reinforcing bar extends into the interior of the concrete wall, and the other end extends into the interior of the slope, so that the concrete wall is tightly connected to the slope soil, which enhances the overall stability. When soil and rocks slide down the slope, the concrete wall prevents them from sliding down, and the reinforcing bar prevents the protective dam from shifting or being damaged by anchoring with the slope soil.

[0015] 3. The biodegradable film wraps around the plant seeds, which initially protects them from adverse external factors such as birds pecking at them or excessive rain washing away the seeds. As time goes by, the biodegradable film gradually degrades, and the plant seeds absorb water and nutrients from the soil to germinate and grow. The plant roots penetrate deep into the soil, further consolidating the soil and improving the slope's resistance to erosion.

[0016] 4. The pressure plate presses the edges or bends of the protective blanket tightly. Multiple second ground cones, evenly installed at the bottom of the pressure plate, penetrate the protective blanket and insert into the soil layer, acting like multiple anchor points to firmly fix the pressure plate and the protective blanket on the slope. When the protective blanket is subjected to lateral force or rolling force, the second ground cones and the pressure plate work together to prevent the protective blanket from shifting or deforming.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 One embodiment provided by this utility model:

[0024] A slope protection structure for water conservancy construction includes a slope 2, a protective dam 3, and a slope protection mechanism 1. The protective dam 3 is built at the bottom of the slope 2, and the slope protection mechanism 1 covers the upper side of the slope 2. The slope protection mechanism 1 consists of a protective blanket 6, a first fixing mechanism 7, and a second fixing mechanism 8. The second fixing mechanism 8 is installed on both longitudinal sides of the protective blanket 6 and at the bends of the protective blanket 6. The first fixing mechanism 7 is fixed at the inclined position of the protective blanket 6. The protective blanket 6 consists of a planting blanket 13 and a protective net 14. The planting blanket 13 is compositely pasted at the bottom of the protective net 14.

[0025] Furthermore, the protective net 14 is configured as either a polybutylene succinate (PBS) net or a polylactic acid-glycolic acid copolymer (PLA) net. PBS nets possess a certain strength and toughness, maintaining structural integrity for up to six months. They resist direct soil erosion by rainwater and prevent soil particles from being carried away by water flow. Over time, they gradually degrade in the natural environment, unlike traditional non-degradable protective nets that cause long-term environmental pollution. In the initial stage of protection, they effectively fulfill their protective function, ensuring the safety of the slope 2. Their later degradable nature aligns with environmental protection principles, reducing the cost and difficulty of manual recycling and disposal, making them particularly suitable for areas with sensitive ecological environments.

[0026] Furthermore, the protective dam 3 consists of a concrete wall 4 and reinforcing bars 5. The concrete wall 4 is cast below the slope 2. One end of the reinforcing bar 5 extends into the concrete wall 4, and the other end extends into the slope 2. The concrete wall 4 has high strength and impact resistance. Cast below the slope 2, it forms a barrier. The reinforcing bars 5 extend into the concrete wall 4 and the other end into the slope 2, so that the concrete wall 4 is tightly connected to the soil of the slope 2, which enhances the overall stability. When soil and rocks slide down the slope 2, the concrete wall 4 prevents them from sliding down, and the reinforcing bars 5 prevent the protective dam 3 from shifting or being damaged by anchoring with the soil of the slope 2.

[0027] Furthermore, the planting mat 13 is composed of a biodegradable film 16 and plant seeds 15. The biodegradable film 16 wraps around the outside of the plant seeds 15, protecting them from adverse external factors such as birds pecking at them or excessive rain erosion. As time goes by, the biodegradable film 16 gradually degrades, and the plant seeds 15 absorb water and nutrients from the soil to germinate and grow. The plant roots penetrate deep into the soil, further reinforcing the soil and improving the slope 2's resistance to erosion.

[0028] Furthermore, the biodegradable membrane 16 is configured as one of starch-based biodegradable membrane, cellulose membrane, or polylactic acid membrane. All of these membranes have the property of being decomposed by microorganisms in the natural environment. During the stage of encapsulating plant seeds 15, they provide a relatively stable microenvironment for the plant seeds 15. Over time, the molecular chains in the membrane material gradually break down under the action of enzymes secreted by microorganisms, and eventually decompose into small molecules that are harmless to the environment.

[0029] Furthermore, the first fixing mechanism 7 consists of a limiting plate 11 and a first ground cone 12. The upper end of the first ground cone 12 is welded to the bottom end of the limiting plate 11. The first ground cone 12 passes through the protective blanket 6 and inserts into the soil layer. The limiting plate 11 restricts the position of the protective blanket 6. The first ground cone 12 passes through the protective blanket 6 and inserts into the soil layer. By utilizing the friction and anchoring force of the soil on the first ground cone 12, the limiting plate 11 and the protective blanket 6 connected thereto are fixed on the slope 2. When the protective blanket 6 is subjected to the tension generated by the slope water flow or soil displacement, the first ground cone 12 can effectively resist the tension and prevent the protective blanket 6 from sliding.

[0030] Furthermore, the second fixing mechanism 8 consists of a pressure plate 9 and a second ground cone 10. The second ground cone 10 is evenly installed at the bottom of the pressure plate 9. The second ground cone 10 passes through the protective blanket 6 and inserts into the soil layer. The pressure plate 9 presses the edge or bend of the protective blanket 6 tightly. Multiple second ground cones 10 evenly installed at the bottom of the pressure plate 9 pass through the protective blanket 6 and insert into the soil layer, which acts like multiple anchor points to firmly fix the pressure plate 9 and the protective blanket 6 on the slope 2. When the protective blanket 6 is subjected to lateral force or rolling force, the second ground cone 10 and the pressure plate 9 work together to prevent the protective blanket 6 from displacing or deforming.

[0031] Working principle: The protective dam 3 is built at the bottom of the slope 2 to block soil and rocks from sliding down the slope 2, reducing the impact on the area below. The slope protection mechanism 1 covers the slope 2, with the protective blanket 6 playing the main protective role. The first fixing mechanism 7 and the second fixing mechanism 8 secure the protective blanket 6 to the slope 2 from different positions. Both the first fixing mechanism 7 and the second fixing mechanism 8 are made of polycaprolactone, which can degrade under natural conditions. The second fixing mechanism 8 is installed on both longitudinal sides and at bends of the protective blanket 6 to prevent the edges of the protective blanket 6 from rolling up or sliding. The first fixing mechanism 7 is fixed at the inclined position of the protective blanket 6, further... The protective blanket 6 is designed to enhance the fit between itself and the slope 2, ensuring that it tightly covers the slope 2 and resists rainwater erosion and soil displacement. This combined slope protection mechanism 1 has a clear division of labor, and the settlement of the slope 2 will not be affected by the slope protection mechanism 1. The protective blanket 6 provides comprehensive coverage protection, and the fixing mechanism ensures its stability, effectively preventing soil loss on the slope 2, protecting the stability of the slope 2, and reducing the possibility of geological disasters such as landslides. Over time, the seeds inside the planting blanket 13 will germinate, forming a protective lawn or growing into woody plants, providing long-term protection to the slope 2 through the roots of the plants.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
