DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-6 The embodiments of the present utility model are described in detail.

[0023] Example 1

[0024] The utility model relates to a terrace slope protection structure, comprising a slope protection top plate 1 and a first slope protection surface 2 and a second slope protection surface 3 extending downwardly along the slope protection top plate 1 to opposite sides; wherein the bottom of the slope protection top plate 1 is in contact with the top surface 91 of the ridge 9, the first slope protection surface 2 is located on the side of the ridge 9 facing the upper terrace 100, and is in contact with the side wall of the ridge 9 on this side, and the second slope protection surface 3 is located on the side of the ridge 9 facing the lower terrace 200, and is in contact with the side wall of the ridge 9 on this side.

[0025] Specifically, since the cross-section of most terraced field ridges 9 is trapezoidal, Figure 1-2 As shown, the cross-section of the terrace slope protection structure is trapezoidal, including the slope protection top and the first slope protection surface 2 and the second slope protection surface 3 located on both sides of the slope top, similar to the slope protection structure being a "hat" for the ridge 9. The first slope protection surface 2 and the second slope protection surface 3 are both rectangular in the same shape as the terrace ridge 9. The first slope protection surface 2 is located on the side of the ridge 9 facing the upper terrace 100, and fits tightly with the side wall of the ridge 9, effectively preventing the water flow of the upper terrace 100 from directly scouring the ridge 9, thereby reducing the possibility of damage to the ridge 9. The second slope protection surface 3 is located on the side of the ridge 9 facing the lower terrace 200200, and also fits tightly with the side wall of the ridge 9, which can prevent the water flow of the lower terrace 200 from eroding the ridge.

[0026] In addition, the inclination angle of the slope protection top plate 1 and the extension lengths and inclination angles of the first slope protection surface 2 and the second slope protection surface 3 can be adjusted according to the specific terrain and water flow conditions to achieve the best slope protection effect.

[0027] It should be noted that multiple expansion joints are arranged at equal distances on the slope protection top plate 1. Since the arrangement of expansion joints is a common arrangement in construction projects, the advantages and arrangement methods of expansion joints are not described here in detail. As long as the thermal expansion and contraction phenomenon of the slope protection top plate 1 under temperature changes can be realized and cracks and structural damage caused by temperature differences can be prevented, it will be sufficient.

[0028] Example 2

[0029] This embodiment is an improvement made on the basis of the embodiment 1, the difference being that the first slope protection surface 2 is a concrete slope protection surface.

[0030] Specifically, since the concrete slope protection surface has the advantages of firm structure, good durability, and easy construction, and since the first slope protection surface 2 is a part of the upper terrace, that is, the first slope protection surface 2 is a "ridge" of the upper terrace to a certain extent, based on the above advantages, the first slope protection surface 2 is set as a concrete slope protection surface. It can not only effectively prevent soil erosion and protect the stability of the slope, but also improve the stability of the slope protection structure.

[0031] Example 3

[0032] This embodiment is an improvement made on the basis of the embodiment 2, and the difference lies in that a plurality of mutually parallel first drainage ditches 21 are further provided on the first slope protection surface 2; on the first slope protection surface 2, a plurality of the first drainage ditches 21 extend in the vertical direction of the first slope protection surface 2.

[0033] In order to avoid water accumulation on the slope protection top plate 1 due to rain, quickly and effectively drain the accumulated water on the slope protection surface to prevent the accumulated water from eroding and damaging the slope protection structure, a plurality of first drainage ditches 21 are arranged on the first slope protection surface 2, such as Figure 4 As shown, the first drainage ditch 21 is arranged along the vertical direction of the first slope protection surface 2. When there is accumulated water on the slope protection top plate 1, it can be discharged from the slope protection top plate 1 through the first drainage ditch 21 and flow into the upper terrace.

[0034] In order to improve the uniformity and efficiency of drainage, a plurality of first drainage ditches 21 are arranged in parallel. The advantages of the parallel arrangement include: when rainwater or other water sources flow down from the first slope protection surface 2, the parallel drainage ditches can ensure that the water flows smoothly along the set path without flowing everywhere, thereby effectively reducing the possibility of soil erosion. In addition, the vertical arrangement helps to maximize the use of gravity, speed up the drainage speed, and prevent water from staying on the first slope protection surface 2 for too long.

[0035] Example 4

[0036] This embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that the second slope protection surface 3 is a concrete frame structure, and green plants are planted in the frame.

[0037] Specifically, since the second slope protection surface 3 faces the lower terrace and mainly supports the ridge 9, and the lower terrace 200 has less erosion on the second slope protection surface 3, the second slope protection surface 3 is designed as a concrete frame structure, and green plants are planted in the frame to form a comprehensive slope protection system composed of plants and engineering, which enhances the stability of the slope while further ensuring the safety of the slope protection.

[0038] The concrete frame can be a rectangular frame, a triangular frame, a square frame, etc., which can all realize the above technical solution, such as Figure 3 As shown, a V-shaped slat is preferred in this application. The V-shaped concrete slat not only has sufficient bearing capacity, but also can prevent soil erosion and water scouring, thereby protecting the slope from natural factors. In addition, the concrete slat ensures the long-term safety of the slope with its sturdy and durable characteristics.

[0039] Example 5

[0040] This embodiment is an improvement made on the basis of the embodiment 4, and the difference is that the concrete frame includes a top beam 4, a ground beam 5, an edge beam 6 and a frame beam 7; wherein, the frame beam 7, i.e., a V-shaped frame, is a plurality of frame beams 7, and at least two edge beams 6 are evenly arranged along the transverse direction of the second slope protection surface 3; there are at least two edge beams 6, and at least two edge beams 6 are respectively located at the two ends of the transverse direction of the second slope protection surface 3; the top beam 4 is arranged at the top of the slope, and the two ends of the top beam 4 are respectively connected to the upper ends of the edge beams 6 at the two ends of the transverse direction of the second slope protection surface 3, and the upper end of the frame beam 7 is connected to the top beam 4; the ground beam 5 is arranged at the bottom of the slope, and the two ends of the ground beam 5 are respectively connected to the lower ends of the edge beams 6 at the two ends of the transverse direction of the second slope protection surface 3, and the lower end of the frame beam 7 is connected to the ground beam 5. Here, the top beam 4 is connected to the slope protection top plate 1, for example, connected and fixed by steel bars. The frame beam 7 is arranged obliquely relative to the top beam 4, and two adjacent frame beams 7 are arranged in a V shape.

[0041] Specifically, the top beam 4, as an important component of the frame, not only bears the pressure from the top, but also connects the entire frame structure tightly together through the connection with the slope protection top plate 1, thereby enhancing the impact resistance of the entire slope protection. The ground beam 5 is responsible for bearing the soil pressure from the bottom, and is connected to the lower ends of the frame beam 7 and the edge beam 6 to form a stable support system. This structure enables the soil to effectively disperse pressure when subjected to external forces, reducing the risk of soil erosion and landslides. The provision of the edge beam 6 further enhances the stability of the frame structure. At least two edge beams 6 are located at both ends of the second slope protection surface 3 in the transverse direction, forming a closed frame structure, which effectively prevents soil overflow and erosion.

[0042] In addition, the lattice beams 7 are evenly arranged laterally along the second slope protection surface 3, and two adjacent lattice beams 7 form a V shape, which not only enhances the overall stability of the slope protection, but also helps to disperse and transmit pressure from different directions, thereby improving the bearing capacity of the slope protection.

[0043] Example 6

[0044] This embodiment is an improvement made on the basis of Embodiment 1, and the difference lies in that it also includes a second drainage ditch 8 opened on the second slope protection surface 3, the second drainage ditch 8 extends in the vertical direction along the second slope protection surface 3, and extends from the second slope protection surface 3 in the vertical direction to the slope protection top plate 1, the second drainage ditch 8 has a bottom wall and two side walls 83 located on the bottom wall 82 and arranged in a mirror image, the bottom of the bottom wall 82 is provided with a second drainage ditch bottom plate 81, and the two side walls 83 are both concrete structures.

[0045] Specifically, in order to drain the water on the top surface of the slope protection 1 to the lower terrace 200, further avoid water accumulation on the top of the slope protection 1, and when there is a lot of rain, causing the water in the upper terrace to overflow, in order to drain the water in the upper terrace 100 as soon as possible, Figure 3 , Figure 5 and Figure 6 As shown, a second drainage ditch 8 is arranged in the vertical direction of the second slope protection surface 3, and the second drainage ditch 8 extends from the second slope protection surface 3 to the slope protection top plate 1 in the vertical direction, that is, the second drainage ditch 8 passes through the slope protection top plate 1 and the second slope protection surface 3. In order to enhance the stability of the drainage ditch, the side walls 83 on both sides of the second drainage ditch 8 are concrete structures to prevent water from entering the ridge 9 from the side walls 83 of the second drainage ditch 8, affecting the ridge 9 and then causing the ridge 9 to collapse. Similarly, a second drainage ditch bottom plate 81 is also arranged at the bottom of the bottom wall of the second drainage ditch 8 to ensure that the water flow can be discharged smoothly and avoid water accumulation from damaging the slope protection structure.

[0046] Example 7

[0047] This embodiment is an improvement made on the basis of Embodiment 1, and the difference lies in that it also includes a plurality of second drainage ditches 8 opened on the second slope protection surface 3, each of the second drainage ditches 8 extends in the vertical direction of the second slope protection surface 3, and extends from the second slope protection surface 3 in the vertical direction to the slope protection top plate 1, and two adjacent second drainage ditches 8 are parallel to each other; the second drainage ditch 8 has a bottom wall and two side walls 83 located on the bottom wall 82 and arranged in a mirror image, the bottom of the bottom wall 82 is provided with a second drainage ditch bottom plate 81, and the two side walls 83 are both concrete structures.

[0048] Specifically, in order to drain the water on the top surface 1 of the slope protection to the lower terrace 200, further avoid water accumulation on the top of the slope protection plate 1, and when there is a lot of rain, causing the water in the upper terrace to overflow, in order to drain the water in the upper terrace 100 as soon as possible, multiple second drainage ditches 8 can be arranged in the vertical direction of the second slope protection surface 3, and each second drainage ditch 8 is parallel to each other, which means that they can evenly share the water flow and avoid a certain area from being subjected to excessive water flow pressure. This uniformly distributed design principle not only improves the durability of the slope protection structure, but also helps to reduce the scouring of the soil by water flow, thereby protecting the stability of the slope.

[0049] Example 8

[0050] This embodiment is an improvement made on the basis of the embodiment 6, the difference being that the slope protection top plate 1 is 35-45 cm wide and 15-25 cm high; the ground beam 5 is 25-35 cm wide and 35-45 cm high.

[0051] Specifically, since the width of the top of most terraces is about 40 cm, the width of the slope protection top plate 1 is set at 35-45 cm, preferably 40 cm, and the height of the slope protection top plate 1 is preferably 20 cm. Similarly, in order to ensure the stability of the slope protection structure, the width of the ground beam 5 is set to 25-35 cm, and the preferred width is 30 cm and the height is 40 cm in this application. The above dimensions not only meet conventional engineering standards, can ensure the stability and durability of the structure, but also effectively disperse the scouring force of the slope water flow on the soil, and can prevent soil erosion and landslides, thereby ensuring the stability of the slope.

[0052] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
