Embodiment 1
[0044] Example 1, such as Figure 1-3 Shown, a kind of high and steep rock slope ecological restoration system described in the embodiment of the present invention, this system comprises:
[0045] Concrete layer 1, which is directly sprayed on the surface of high and steep rock slope; concrete layer 1 includes sandy soil and cement, wherein sandy soil accounts for 80%-85% of the total weight, cement accounts for 15%-20% of the total weight, concrete The thickness of layer 1 is 2cm-3cm, the cement is 425# cement, and the sand content of the sandy soil is not more than 5%. Concrete layer 1 protects the steep rocky slope and serves as the base of the system.
[0046] Optionally, the concrete layer 1 includes 80% sandy soil and 20% cement, and the thickness of the concrete layer 1 is 2 cm.
[0047] Optionally, the concrete layer 1 includes 85% sandy soil and 15% cement, and the thickness of the concrete layer 1 is 3 cm.
[0048] The above optional matching ratios are only optio...
Embodiment 2
[0071] Example 2, such as Figure 1-3 Shown, the present invention also provides a kind of high and steep rock slope ecological restoration method, and this method comprises the following steps:
[0072] Step 1: Clean up the slope, level the rock slope to be repaired, remove floating soil and dangerous stones, and clean the rock slope with a high-pressure water gun; build gutters and drainage ditches at the same time.
[0073] Step 2: Fix the anchor rod 8, drill the hole according to the design standard, insert the anchor rod 8 after forming the hole once, and fix the anchor rod 8;
[0074] Step 3: spray concrete layer 1, and spray concrete on the prepared rock slope;
[0075] Step 4: Lay the first protective net layer 2, pull the support rope on the anchor rod 8, and lay a mesh on the support rope to cover the entire rock slope to be repaired;
[0076] Step 5: Spray the mixed material base layer 3, and spray the mixed material on the laid first protective net layer 2;
