[0002] The greening of highway slopes is not only related to the use effect of highways, but also reflects the development status of a city. The purpose of slope greening is to use vegetation combined with relevant civil engineering technologies to improve the beautification of highways while further enhancing the anti-corrosion ability of highways and extending the service life of highways.

[0003] One of the principles of highway slope greening is the hydrological effect of vegetation. By covering the highway slope with vegetation, the effects of protecting the slope, preventing soil erosion, and improving the quality of the ecological environment can be achieved. The hydrological effect refers to the process by which vegetation regulates the circulation and distribution of water through root water absorption, transpiration, and rainwater interception. In highway slope greening, vegetation can play a role in absorbing water and maintaining soil stability, because the roots of vegetation can absorb water from the soil, reduce the moisture content in the soil, thereby reducing the saturation of the soil, enhancing the soil's ability to resist erosion, and maintaining the stability of the slope.

[0004] In addition to utilizing the hydrological effects of vegetation, highway slope greening also utilizes the mechanical effects of vegetation. First, vegetation coverage can achieve the effect of anti-slip slope protection. The root system of vegetation can firmly fix soil particles and increase the shear strength of the soil, thereby improving the stability and anti-slip properties of the slope. The root system of vegetation can penetrate the soil and form a mesh structure to prevent the loosening of the soil and the occurrence of landslides. In addition, the root system can also increase the cohesion and internal friction angle of the soil, increase the shear strength of the soil, and reduce the risk of landslides.

Moreover, since the fixing plate 24 rotates with the inner chamber 17, the driving rotating rod 23 can rotate more stably.

[0038] like Figure 5 and 7 As shown, the top of the driving rod 23 extends out of the inner chamber 17 through the top opening 18, and the driving rod 23 rotates with the top opening 18. After the driving rod 23 passes through the top opening 18, it is coaxially fixedly connected with a knob 25. The outer wall of the knob 25 has anti-slip texture 26. The knob 25 is used to provide a force point for the worker to rotate the driving rod 23.

[0039] like Figure 5 and 7 As shown, a hinged disc 27 is coaxially fixedly connected to the driving rod 23, and the hinged disc 27 is located below the fixed plate 24. The cross-section of the hinged disc 27 is a circular ring. The hinged disc 27 and the four guide plate sliding holes 19 are coplanar in the horizontal direction, and four second pins 28 are equidistantly arranged on the upper and lower end surfaces of the hinged disc 27.

[0040] like Figure 5 and 7As shown, one end of the connecting rod 29 is hinged to the hinge seat 21 through the first pin 22, and the other end is hinged to the hinge disk 27 through the second pin 28. There are two connecting rods 29 between the hinge disk 27 and each hinge seat 21. The two connecting rods 29 are symmetrically arranged on both sides of the hinge disk 27. Two connecting rods 29 are arranged between the driving rotating rod 23 and the locking cover slide 20, which is beneficial to improve the connection stability between the driving rotating rod 23 and the locking cover slide 20.

[0041] like Figure 5 and 7 As shown, a plate rod rotation limiting hole 30 is provided on the outer wall of the housing 14, the plate rod rotation limiting hole 30 is located above the guide plate slide hole 19, the plate rod rotation limiting hole 30 is connected to the inner chamber 17, and the plate rod rotation limiting hole 30 is a circular hole. A plate rod rotation limiting groove 31 is provided on the side wall of the fixed plate 24, the cross section of the plate rod rotation limiting groove 31 is circular, the plate rod rotation limiting groove 31 and the plate rod rotation limiting hole 30 are coplanar in the horizontal direction, so when the fixed plate 24 rotates, the plate rod rotation limiting groove 31 can be aligned with the plate rod rotation limiting hole 30. A plate rod rotation limiting buckle 32 is slidably provided in the plate rod rotation limiting groove 31, and the plate rod rotation limiting buckle 32 is in the shape of a bullet head. A return spring 33 is provided between the bottom of the plate rod rotation limiting slot 31 and the plate rod rotation limiting buckle 32. One end of the return spring 33 is connected to the bottom of the plate rod rotation limiting slot 31, and the other end is connected to the plate rod rotation limiting buckle 32. The return spring 33 is used to push the plate rod rotation limiting buckle 32 to embed into the plate rod rotation limiting clamping hole 30, thereby limiting the fixed plate 24 and driving the rotating rod 23 to rotate.

[0042] The detailed installation process of the vegetation shield 9 in this embodiment is as follows:

[0043] S1: The worker aligns the four mounting holes 12 of the vegetation shield 9 with the four shield locks 13 on the pedestrian ramp 6, and then passes the housing 14 of the shield lock 13 through the mounting holes 12, while making the mounting plate 11 fit the surface of the pedestrian ramp 6;

[0044] S2: The worker then turns the driving rod 23 and the hinged disc 27 through the knob 25. The rotation of the hinged disc 27 will drive the locking cover slide 20 to move away from the driving rod 23 through the connecting rod 29 until the locking cover slide 20 extends out of the guide plate slide hole 19. At the same time, when the fixed rotation makes the plate rod rotation limit slide groove 31 aligned with the plate rod rotation limit card hole 30, the return spring 33 pushes the plate rod rotation limit buckle 32 to embed into the plate rod rotation limit card hole 30, and the fixed plate 24 and the driving rod 23 are restricted from rotating. At this time, the bottom surface of the locking cover slide 20 remains on the turntable against the top surface of the mounting plate 11, and the vegetation cover 9 is restricted from moving.

[0045] The rock slope ecological slope protection structure provides a vegetation cover 9 on the pedestrian ramp 6, so that the vegetation is not easily trampled, which is beneficial to protecting the normal growth of the vegetation.

[0046] The ecological slope protection structure of the rock slope realizes the function of quick disassembly and assembly of the vegetation shield 9 by setting the shield fixing device, which is beneficial to improving the disassembly and assembly efficiency of the vegetation shield 9.
