Through the second main body part 92 with an inverted trapezoid structure, it is convenient to connect with the road 11 and the mountain body 1, and at the same time, the stability of the protection main body 9 can be improved. In other embodiments, the second main body part 92 can also be of other shapes, and can be adjusted according to application scenarios and the like in different embodiments. For example, the second main body part 92 can also be square or other irregular shapes.

[0036] Optionally, the protection main body 9 is an integrated structure, and the first main body part 91 is connected to the second main body part 92.

[0037] In the embodiment of the present application, the protection main body 9 can be integrally formed by pouring, however, this does not constitute a limitation to the embodiment of the present application. In different embodiments, it can also be formed separately and fixedly connected to realize the fixed connection between the first main body part 91 and the second main body part 92.

[0038] In this embodiment, the water discharge hole 7 is provided at one end of the first main body part 91 close to the second main body part 92, and the water discharge hole 7 is inclined downward along the direction from the mountain body 1 to the road 11. Through the inclined water discharge hole 7, the water discharge effect can be improved. The number and arrangement mode of the water discharge holes 7 are not limited in the embodiment of the present application, and can be adjusted according to needs in different embodiments.

[0039] In another embodiment of the present application, the filter water area 82 is provided with a gravel layer 6 laid in multiple layers. The top surface of the gravel layer 6 far from the second main body part 92 is lower than the first main body part 91; the bottom surface of the gravel layer 6 close to the second main body part 92 is at least lower than one side of the water discharge hole 7 close to the gravel layer 6.

[0040] The water filtration area 82 laid through the gravel layer 6 can facilitate drainage, increase the drainage area, and improve the drainage performance. In this embodiment, the bottom height of the gravel is slightly lower than that of the water discharge hole 7 to avoid blockage of the water discharge hole 7. The top height of the gravel layer 6 is slightly lower than that of the first main body 91. On the one hand, it can ensure the effect of blocking the falling rocks and rainwater on the mountain body 1. In addition, the first main body 91 can further ensure the stability of the gravel layer 6 and prevent the gravel layer 6 from rolling down.

[0041] Optionally, the gravel layer 6 includes a first gravel layer 6 and a second gravel layer 6 laid in a stacked manner. The first gravel layer 6 is arranged on the side close to the second main body 92. The first gravel layer 6 is in contact with the mountain body 1. The buffer area 81 is arranged between the second gravel layer 6 and the mountain body 1, and the buffer area 81 is in contact with the mountain body 1. Among them, natural soil is filled in the buffer area 81, and a vegetation area is provided, and small shrubs 3 can be planted in the vegetation area.

[0042] In this embodiment, a road cutting protection structure applied to a mountain body is provided. The top of the first main body 91 on the protection main body 9, the water filtration area 82 formed by gravel, and the small shrubs 3 in the buffer area 81 together form a protection drainage buffer structure, which can not only collect the rainwater on the mountain body 1, but also buffer the rainwater flowing directly down the mountain body 1, avoiding the direct scouring of the road 11 when the rainwater flows down from the mountain body 1, resulting in damage to the structure of the road 11 and splashing water, etc., and can also block the falling rocks on the mountain body 1.

[0043] This structural form minimizes the disturbance of the engineering construction to the existing mountain body 1 and its ecological environment, and avoids the disadvantages of large disturbance and wide influence range of traditional retaining walls or slope construction. In addition, a row of small shrubs 3 are planted on the outside of the structure, which not only has the effects of preventing falling rocks and rainwater scouring, but also has ecological and landscape functions. The small shrubs 3 can also filter the dead branches, fallen leaves, etc. mixed in the rainwater on the mountain body 1 to prevent blocking the gravel and affecting the drainage effect.

[0044] Optionally, the protection structure further includes a permeable geotextile 5 arranged on the side of the water filtration area 82 away from the protection main body 9. The permeable geotextile 5 covers the bottom surface of the first gravel layer 6 and extends to the top surface of the second gravel layer 6.

[0045] The permeable geotextile 5 is laid at the bottom and outside of the gravel layer 6 to prevent the soil body from entering the gravel and the water discharge hole 7 with the water flow, affecting the drainage effect. It should be noted that the permeable geotextile 5 is a permeable geosynthetic material made of synthetic fibers by needle punching or weaving. This material has high tensile strength and extensibility, can withstand water pressure and adapt to the deformation of the soil body. The surface of the permeable geotextile 5 is rough, increasing the friction coefficient of the contact surface, which is beneficial to the performance stability of the permeable geotextile 5 and the surrounding structures.

The protection and buffer part 8 is arranged between the first main body part 91 and the mountain body 1. The protection and buffer part 8 is built along the mountain, and the inclined structure of the protection and buffer part 8 can improve the connection effect with the mountain body 1 and enhance the stability. At the same time, it can further buffer rainwater, falling rocks, etc.

[0047] In this embodiment, the top of the gravel layer 6, the small shrubs 3 are flush with the bottom of the natural slope of the mountain body 1. There is a certain slope ratio on the inner side of the first main body part 91 of the protection main body 9, and the bottom width is greater than the top width. That is, the cross-sectional shape of the first main body part 91 in the direction perpendicular to the road 11 is trapezoidal to enhance the structural stability. Of course, in different embodiments, the shape or slope ratio can be adjusted as needed, and the present application does not limit this.

[0049] First, the mountain body 1 is excavated along the outer edge line of the road 11 structure, forming an intersection between the excavation edge line 4 of the mountain body 1 and the natural slope line 2 of the mountain body 1, and temporary protection measures are taken to prevent the collapse of the mountain body 1.

[0050] Then, the excavated ground is compacted by rolling, and the protection main body 9 is poured with C30 cement concrete. The inner slope ratio of the first main body part 91 is 1:0.05, the top width is 0.5 m, and the top of the structure is 0.3 m higher than the top of the gravel. The thickness of the first main body part 91 is 0.4 m, the slopes on both sides are 1:1.5, and the inner bottom width is 0.5 m. The diameter of the drain hole 7 is 0.05 m, with 5 in a group, the hole spacing is 0.15 m, and the group spacing is 2 m, all arranged horizontally.

[0051] After the pouring and curing of the protection main body 9 are completed, a permeable geotextile 5 is laid on the bottom and side of the outer side, and then two layers of gravel layers 6 are laid, where the top width of the gravel layer 6 is 0.2 m and the vertical laying height is 0.5 m.

[0052] After completion, the space formed between the upper part of the permeable geotextile 5 and the excavation edge line of the mountain body 1 is backfilled with natural soil, and a row of small shrubs 3 is planted on it. The width of the top backfilled natural soil is 0.15 m.
