Description

Technical Field

[0001] This utility model relates to the field of land engineering technology, specifically a slope protection structure. Background Technology

[0002] In the field of land engineering infrastructure, slope protection structures are facilities that ensure the safety of engineering projects and the stability of the surrounding ecology. They must simultaneously take into account structural impact resistance, water flow guidance capacity, ecological compatibility, and traffic safety. As engineering construction extends to complex geological areas (such as steep slopes and water-rich areas) and ecologically sensitive areas, traditional slope protection structures have gradually revealed many technical defects and are no longer able to meet the needs of practical applications.

[0003] Existing slope protection structures have certain shortcomings in their water diversion and drainage system design: On the one hand, the water flow diversion path is unreasonable, mostly relying on single downslope drainage without diversion or flow mitigation mechanisms. This leads to concentrated impacts of rainwater or slope water flow on localized areas of the slope, exacerbating slope erosion and even causing collapses. On the other hand, the coordination between drainage and ecological irrigation is poor. Some protection structures with planting troughs lack supporting drainage channels, allowing excessive water to accumulate in the planting troughs, causing plant root rot. Protection systems without irrigation guidance structures cannot utilize natural rainfall for vegetation maintenance, resulting in water waste. Furthermore, existing drainage structures lack multi-stage filtration designs, allowing silt, fallen leaves, and other impurities to easily clog drainage channels, leading to water accumulation and soaking of the slope structure, thus shortening its service life. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a slope protection structure that solves the problems of single-slope drainage lacking diversion and flow mitigation mechanisms, poor coordination between drainage and ecological irrigation, and lack of multi-stage filtration design, which leads to water accumulation and soaking of the main slope. After secondary filtration, rainwater flows into the top drainage channel through the second grid mesh, achieving rapid rainwater dispersal. Through the diversion design, it avoids the concentrated impact of a single water flow on the water guide plate, reducing the local stress load. Excess water flows into the drainage side channel through the connection between the bottom of the planting trough and the drainage side channel, and is then discharged from the main slope.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slope protection structure, comprising a slope component, a walkway component, and a water guiding component. The slope component includes a slope body, the walkway component includes a walkway sidewall, and the water guiding component includes a water guiding plate. The top of the slope body is fixedly connected to a top slope layer via pre-embedded reinforced concrete. The front end of the slope body is fixedly connected to a bottom slope layer via cast-in-place concrete. A bottom slope inlet groove is integrally formed on the inner side of the upper part of the bottom slope layer. Planting troughs are spaced apart along the length of the inner side of one end of the slope body. An installation base plate is fixedly connected to the top of the walkway sidewall via pre-embedded bolts. One end of the top slope layer is integrally formed and fixedly connected to a stabilizing protective layer. A drainage top groove is formed through the inner side of the stabilizing protective layer along its length.

[0006] The beneficial effects of this utility model are as follows: the slow-flow channel and the longitudinally arranged water guide channel cooperate to form a grid-like water guiding structure, which improves the guiding and diversion coverage of the water flow. The water body diverted from the diversion channel first flows into the slow-flow channel. The water flow path is extended by the transverse slow-flow channel, which slows down the water flow speed. The slow-flow channel distributes the water body to each longitudinal water guide channel, avoiding local water flow overload and further reducing the impact of the water flow on the water guide plate and the main body of the slope.

[0007] To prevent water from accumulating at the bottom of the slope and causing structural saturation damage: As a further improvement to the above technical solution: the bottom layer of the slope away from the main body of the slope is integrally formed with a bottom drainage groove, and the bottom drainage groove and the bottom water inlet groove are L-shaped and sealed in communication.

[0008] The beneficial effects of this improvement are as follows: the water flows downward along the slope's main inclination direction under the action of gravity through the water guide channel of the water guide component. After being precisely guided by the water guide channel, it enters the bottom water inlet channel. The water in the bottom water inlet channel is quickly discharged from the bottom of the slope through the channel that connects to the bottom drainage channel, thus avoiding water accumulation at the bottom of the slope that could cause structural damage from soaking.

[0009] To allow excess water to flow into the drainage side channel through the connection between the bottom of the planting trough and the drainage side channel, and then be discharged from the main body of the slope: As a further improvement to the above technical solution: drainage side channels are provided at intervals along the length direction on the inner side of one end of the slope body, the drainage side channels are connected to the bottom of the corresponding planting troughs, and the planting troughs are provided at equal intervals along the length direction of the slope body.

[0010] The beneficial effects of this improvement are as follows: After the water flows down the guide channel, it is diverted and guided into the planting trough. The water entering the planting trough provides irrigation water for the slope stabilizing plants cultivated in the trough. When the water level in the planting trough exceeds the preset height, the excess water flows into the drainage side channel through the connection between the bottom of the planting trough and the drainage side channel, and then is discharged from the main body of the slope. The planting trough is used to cultivate native slope stabilizing plants and enhance the structural stability of the slope.

[0011] The safety netting along the walkway is designed to prevent people and objects from falling from either side of the top layer of the slope, ensuring the safety of pedestrians in the walkway area at the top layer of the slope. As a further improvement to the above technical solution: the first walkway side wall includes a second walkway side wall that is symmetrically arranged. The first walkway side wall and the second walkway side wall are symmetrically fixed to the top two sides of the top layer of the slope by pre-embedded anchor rods. The end of the mounting base away from the first walkway side wall is fixedly connected to the walkway protective net by bolts. The walkway protective net is continuously arranged along the length direction of the top layer of the slope and has a height of 2.1m.

[0012] The beneficial effects of this improvement are as follows: Walkway sidewall 1 and walkway sidewall 2 are fixed to the concrete structure of the top layer of the slope through pre-embedded anchor rods, forming a vertical and stable support for the installation base plate. The installation base plate provides the installation foundation for the walkway safety net. When in use, the walkway safety net is used to prevent people and objects from falling from both sides of the top layer of the slope, ensuring the safety of pedestrians in the walkway area of ​​the top layer of the slope.

[0013] To ensure rapid rainwater dissipation and prevent rainwater from accumulating and soaking in the top walkway area of ​​the slope, thus preventing damage to the top structure of the slope: As a further improvement to the above technical solution: a first grid mesh and a second grid mesh are fixedly connected to the lower part of the walkway sidewall through an embedded structure. The first grid mesh and the second grid mesh are arranged in parallel and spaced apart to form a hollow filter trough. The trough is filled with permeable geotextile. The first grid mesh is embedded on the side of the walkway sidewall one near the side of the walkway sidewall two, and the second grid mesh is embedded on the side of the walkway sidewall one near the stable protective layer.

[0014] The beneficial effects of this improvement are as follows: rainwater in the top walkway area of ​​the slope first comes into contact with the first grid mesh, and is initially filtered by the first grid mesh to intercept large particles of debris such as fallen leaves and gravel. The filtered rainwater flows into the hollow trough between the first grid mesh and the second grid mesh, and is then filtered a second time by the permeable geotextile inside the trough to remove fine impurities such as mud and sand. The rainwater after the second filtration flows into the top drainage trough through the second grid mesh, realizing the rapid dispersal of rainwater and preventing rainwater from accumulating and soaking in the top walkway area of ​​the slope, thus preventing damage to the top structure of the slope.

[0015] To avoid concentrated impact of a single water flow on the water guide plate and reduce local stress load: As a further improvement to the above technical solution: a diversion channel is provided along the height direction on the side of the slope body that is in contact with the water guide plate. The top of the diversion channel is integrally formed and connected to the outlet end of the drainage side channel. The diversion channel is inclined with the slope of the slope body, and its bottom is flush with and correspondingly attached to the top end face of the water guide plate.

[0016] The beneficial effects of this improvement are as follows: the water discharged from the drainage side channel forms two water flows. The first water flow flows directly along the main slope surface of the side slope to the water guide plate below. The second water flow is diverted to the top end face of the water guide plate through the inclined guiding effect of the diversion channel. Through the diversion design, the single water flow is prevented from concentrating and impacting the water guide plate, thus reducing the local stress load.

[0017] To disperse a single concentrated water flow into multiple smaller streams, these smaller streams flow directionally along the guide channel to reduce water velocity and scouring force: As a further improvement to the above technical solution: the water guide plate is detachably and fixedly connected to the slope surface of the slope body by expansion bolts, and a number of water guide grooves are opened on the surface of the water guide plate along its inclined direction, and the water guide grooves are arranged at equal intervals along the length direction of the water guide plate.

[0018] The beneficial effects of this improvement are as follows: when rainwater or slope runoff impacts the water-guiding plate, the plate surface directly resists the impact force of the water flow, using its own structural strength to block the water flow from directly scouring the main slope surface. At the same time, the water-guiding channel guides and diverts the concentrated water flow, dispersing the single concentrated water flow into multiple fine streams. The diverted fine streams flow directionally along the water-guiding channel to reduce the water flow speed and scouring force, ensuring the tightness of the connection between the water-guiding plate and the main slope surface, and preventing the plate from falling off due to water impact.

[0019] In order to distribute water to each longitudinal guide channel and avoid local overload of water flow in the guide channels, and further reduce the impact of water flow on the guide plate and the main slope: As a further improvement to the above technical solution: a transverse flow-slowing groove is provided on the top end face of the water guide plate. The flow-slowing groove is arranged along the water guide plate and has a transverse through structure. Its two ends are respectively connected to the water guide grooves on both sides of the water guide plate.

[0020] The beneficial effects of this improvement are as follows: the slow-flow channel, together with the longitudinally arranged water guide channel, forms a grid-like water guiding structure, which improves the guiding and diversion coverage of the water flow. The water body diverted from the diversion channel first flows into the slow-flow channel, and the water flow path is extended by the transverse slow-flow channel to slow down the water flow speed. The slow-flow channel distributes the water body to each longitudinal water guide channel, avoiding local water flow overload, and further reducing the impact of the water flow on the water guide plate and the main body of the slope.

[0021] In summary, the beneficial effects of this project are as follows: the flow-retarding channel distributes water to each longitudinal guide channel, avoiding local overload of the guide channel water flow, further reducing the impact force of the water flow on the guide plate and the main body of the slope, and diverting the water to the top end face of the guide plate. Through the diversion design, it avoids the concentrated impact of a single stream of water on the guide plate, reducing the local stress load. The diverted streams flow directionally along the guide channel to slow down the water flow velocity and scouring force, ensuring the tightness of the connection between the guide plate and the main body of the slope, and preventing the plate from falling off due to water flow impact.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0030] like Figure 1-5As shown, a slope protection structure includes a slope component 1, a walkway component 2, and a water guiding component 3. The slope component 1 includes a slope body 11, the walkway component 2 includes a walkway sidewall 21, and the water guiding component 3 includes a water guiding plate 31. The top of the slope body 11 is fixedly connected to a top slope layer 12 by pre-embedded reinforced concrete. The front end of the slope body 11 is fixedly connected to a bottom slope layer 13 by cast-in-place concrete. A bottom slope inlet groove 14 is integrally formed on the inner side of the upper part of the bottom slope layer 13. Planting grooves 16 are spaced apart along the length direction on the inner side of one end of the slope body 11. An installation base plate 22 is fixedly connected to the top of the walkway sidewall 21 by pre-embedded bolts. One end of the top slope layer 12 is integrally formed and fixedly connected to a stable protection layer 25. A drainage top groove 26 is formed through the inner side of the stable protection layer 25 along its length direction.

[0031] The bottom layer 13 of the slope is integrally formed with a bottom drainage channel 15 at the end away from the main body of the slope 11. The bottom drainage channel 15 and the bottom water inlet channel 14 are connected in an L-shape. Water flows downward along the inclined direction of the main body of the slope 11 under the action of gravity through the water guide channel 32 of the water guide component 3. After being precisely guided by the water guide channel 32, it enters the bottom water inlet channel 14. The water in the bottom water inlet channel 14 is quickly discharged from the bottom layer 13 of the slope through the channel connected to the bottom drainage channel 15, so as to avoid water accumulation in the bottom layer 13 of the slope and damage to the structure caused by soaking.

[0032] The inner side of one end of the slope body 11 is provided with drainage side channels 17 at intervals along the length direction. The drainage side channels 17 are connected to the bottom of the corresponding planting troughs 16. The planting troughs 16 are equally spaced along the length direction of the slope body 11. After the water flows down the water guide channel 32, it is diverted and guided into the planting trough 16. The water entering the planting trough 16 provides irrigation water for the slope stabilizing plants cultivated in the trough. When the water level in the planting trough 16 exceeds the preset height, the excess water flows into the drainage side channel 17 through the connection between the bottom of the planting trough 16 and the drainage side channel 17, and then is discharged from the slope body 11. The planting trough 16 is used to cultivate native slope stabilizing plants and enhance the structural stability of the slope.

[0033] The first walkway side wall 21 includes a second walkway side wall 211 symmetrically arranged. The first walkway side wall 21 and the second walkway side wall 211 are symmetrically fixed to the top two sides of the top layer of the slope 12 by pre-embedded anchor rods. The end of the mounting base plate 22 away from the first walkway side wall 21 is fixedly connected to the walkway safety net 23 by bolts. The walkway safety net 23 is continuously arranged along the length of the top layer of the slope 12 with a height of 2.1m. The first walkway side wall 21 and the second walkway side wall 211 are fixed to the concrete structure of the top layer of the slope 12 by pre-embedded anchor rods, forming a vertical and stable support for the mounting base plate 22. The mounting base plate 22 provides the installation foundation for the walkway safety net 23. In use, the walkway safety net 23 is used to prevent people and objects from falling from both sides of the top layer of the slope 12, ensuring the safety of people walking in the walkway area of ​​the top layer of the slope 12.

[0034] The lower part of the walkway sidewall 21 is fixedly connected to a first grid mesh 24 and a second grid mesh 241 by an embedded structure. The first grid mesh 24 and the second grid mesh 241 are arranged in parallel and spaced apart to form a hollow filter trough. The trough is filled with permeable geotextile. The first grid mesh 24 is embedded on the side of the walkway sidewall 21 near the second walkway sidewall 211, and the second grid mesh 241 is embedded on the side of the walkway sidewall 21 near the stable protective layer 25. Rainwater in the walkway area of ​​the top slope 12 first comes into contact with the first grid mesh 24. After preliminary filtration by the first grid mesh 24, large particles of fallen leaves and gravel are intercepted. The filtered rainwater flows into the hollow trough between the first grid mesh 24 and the second grid mesh 241. After secondary filtration by the permeable geotextile in the trough, fine impurities such as mud and sand are removed. The rainwater after secondary filtration flows into the drainage top trough 26 through the second grid mesh 241, realizing rapid rainwater dispersal and preventing rainwater from accumulating and soaking in the walkway area of ​​the top slope 12, thus preventing damage to the top slope structure.

[0035] A diversion channel 18 is provided along the height direction on the side of the slope body 11 that is in contact with the water guide plate 31. The top of the diversion channel 18 is integrally formed and connected to the outlet end of the drainage side channel 17. The diversion channel 18 is inclined with the slope of the slope body 11, and its bottom is flush with and correspondingly attached to the top end face of the water guide plate 31. The water discharged from the drainage side channel 17 forms two water flows. The first water flow flows directly along the slope surface of the slope body 11 to the water guide plate 31 below. The second water flow is diverted to the top end face of the water guide plate 31 by the inclined guiding effect of the diversion channel 18. Through the diversion design, the single water flow is prevented from concentrating and impacting the water guide plate 31, and the local stress load is reduced.

[0036] The water-guiding plate 31 is detachably and fixedly connected to the slope surface of the slope body 11 by expansion bolts. The surface of the water-guiding plate 31 is provided with a plurality of water-guiding grooves 32 along its inclined direction. The water-guiding grooves 32 are arranged at equal intervals along the length of the water-guiding plate 31. When rainwater or slope water impacts the water-guiding plate 31, the plate surface of the water-guiding plate 31 directly resists the impact force of the water flow and uses its own structural strength to block the water flow from directly scouring the slope surface of the slope body 11. At the same time, the water-guiding grooves 32 guide and divert the concentrated water flow, dispersing the single concentrated water flow into multiple fine streams. The diverted fine streams flow directionally along the water-guiding grooves 32 to reduce the water flow speed and scouring force, ensure the connection and tightness between the water-guiding plate 31 and the slope body 11, and prevent the plate from falling off due to the impact of the water flow.

[0037] The top end face of the water guide plate 31 is provided with a transverse flow-slowing groove 33. The flow-slowing groove 33 is arranged along the water guide plate 31 and has a transverse through structure. Its two ends are respectively connected to the water guide channels 32 on both sides of the water guide plate 31. The flow-slowing groove 33 cooperates with the longitudinally arranged water guide channels 32 to form a grid-like water guiding structure, which improves the guiding and diversion coverage of the water flow. The water body after being diverted from the diversion channel 18 first flows into the flow-slowing groove 33. The flow-slowing groove 33 extends the water flow path and slows down the water flow speed. The flow-slowing groove 33 distributes the water body to each longitudinal water guide channel 32, avoids local water flow overload of the water guide channel 32, and further reduces the impact of the water flow on the water guide plate 31 and the slope body 11.

[0038] The working principle of this utility model is as follows: In use, the first side wall 21 and the second side wall 211 of the walkway are fixed to the concrete structure of the top layer of the slope 12 through pre-embedded anchor rods, forming a vertical and stable support for the mounting base 22. The mounting base 22 provides the installation foundation for the walkway net 23. In use, the walkway net 23 is used to prevent people and objects from falling from both sides of the top layer of the slope 12, ensuring the safety of pedestrians in the walkway area of ​​the top layer of the slope 12. Rainwater in the walkway area of ​​the top layer of the slope 12 first comes into contact with the first grid mesh 24. After preliminary filtration by the first grid mesh 24, fallen leaves, gravel and large particles of impurities are intercepted. The filtered rainwater flows into the hollow trough between the first grid mesh 24 and the second grid mesh 241, and is filtered a second time by the permeable geotextile in the trough to remove fine mud and sand. Impurities and rainwater after secondary filtration flow into the top drainage channel 26 through the second grid 241, achieving rapid rainwater dispersal and preventing rainwater from accumulating and soaking in the top slope 12 walkway area, thus preventing damage to the top slope structure. After flowing downwards along the guide channel 32, the water is diverted and guided into the planting trough 16. The water entering the planting trough 16 provides irrigation water for the slope-stabilizing plants cultivated in the trough. When the water level in the planting trough 16 exceeds the preset height, the excess water flows into the drainage side channel 17 through the connection between the bottom of the planting trough 16 and the drainage side channel 17, and then is discharged from the main slope 11. The planting trough 16 is used to cultivate native slope-stabilizing plants to enhance the stability of the slope structure. The water discharged from the drainage side channel 17 forms two water flows. The first water flow goes directly along the main slope 11. The second stream of water flows downwards along the slope through the diversion channel 18, diverting it to the top surface of the water guide plate 31. This diversion design prevents a single stream of water from concentrating and impacting the water guide plate 31, reducing localized stress. When rainwater or slope runoff impacts the water guide plate 31, its surface directly resists the impact force, using its structural strength to block direct scouring of the slope body 11. Simultaneously, the diversion channel 32 guides and diverts the concentrated water flow, dispersing it into multiple smaller streams. These smaller streams flow directionally along the diversion channel 32, reducing water velocity and scouring force, ensuring the secure connection between the water guide plate 31 and the slope body 11, preventing the plate from detaching due to water impact, and slowing the flow. The channel 33, in conjunction with the longitudinally arranged water guide channel 32, forms a grid-like water guiding structure, enhancing the guiding and diversion coverage of the water flow. Water diverted from the diversion channel 18 first flows into the slow-flow channel 33. The transverse slow-flow channel 33 extends the water flow path, slowing the flow velocity. The slow-flow channel 33 distributes the water to each longitudinal water guide channel 32, preventing overload of local water guide channels 32 and further reducing the impact of the water flow on the water guide plate 31 and the slope body 11. The water flows downwards along the slope body 11 under gravity, following the water guide channel 32 of the water guide component 3. After being precisely guided by the water guide channel 32, it enters the bottom inlet channel 14. The water in the bottom inlet channel 14 is quickly discharged from the bottom slope 13 through its connection with the bottom drainage channel 15.To prevent water from accumulating at the bottom layer of the slope (13), which could lead to structural saturation and damage.
