As shown in Figures 1 and 2, taking a slope with a slope A of 70 degrees as an example, the porous planting and greening system for high and steep slopes provided by the utility model is described. The system includes: several anchor rods 1 , steel mesh 3 , several planting pipes 2 and a fixed layer 4 .

The anchor rod 1 is fixed at the preset anchor rod position, the steel mesh 3 is hung on the anchor rod 1, the planting pipe 2 is fixed at the preset planting position of the steel mesh 3, the fixed layer 4 is covered on the steel mesh 3, and the steel mesh 3 is fixed and planting tube 2.

The determination of anchor bolt position parameters should be determined according to the degree of weathering of surrounding rock, broken condition and slope protection level. In this embodiment, the spacing L1 of each row of anchor positions is 1000 mm, the row spacing L2 is 1000 mm, and the position of the anchors in the next row is in the middle of the positions of the two anchors in the previous row. The position of the anchor rod can be adjusted according to the actual situation, and can be set evenly or non-uniformly.

There is an anchor hole at the preset anchor position, the diameter of the anchor hole is larger than the diameter of the anchor, and the length of the anchor hole is longer than the length of the anchor.

The reinforcement mesh 3 is pre-consolidated with steel bars in accordance with the designed dimensions meeting the stability requirements of the slope. The steel mesh 3 is hung on the anchor rod 1, and is close to the side slope.
