Problems solved by technology

The above various construction methods can only plant vegetation on rocky slopes, and cannot completely restore the slope ecosystem, and the construction volume is large, and the speed of restoration and greening is slow.
In addition, because restorations or green vegetation are all built on the surface of rock slopes, the adhesion is not strong, and they are easy to fall off or collapse, and the above-mentioned various construction methods lack scientific treatment for cracks and broken rocks in rock slopes. After the slope has been exposed to the sun and rain for a long time, it is easy to loosen due to thermal expansion and contraction, which will cause the restoration or green vegetation to fall or the broken rock to fall off, causing safety hazards

Embodiment 1

[0031] Such as figure 1 , 2 As shown, the rocky slope on the side of the expressway is greened by using the ecological restoration method of the rocky slope, and the height of the rocky slope is 5m, which specifically includes the following steps:

[0032] 1) Build the rocky slope into five ladder-like steps, the height of each ladder-like step is 1m, and the surface of each ladder-like step slopes inward and forms an angle of 10 degrees with the ground plane;

[0033] 2) After removing the crushed rock, inject viscose slurry into the cracks. The preparation method of the viscose slurry is: polyurethane prepolymer, cement, slaked lime, water and isopropyl triisostearyl titanate According to the ratio of 3:1:2:3:0.2, mix and stir in the mixing tank evenly to make a viscose slurry, let it stand for 1-2 hours to make the viscose slurry form a viscose slurry layer and a water layer, remove the water layer and stir again Made of viscose slurry; the polyurethane prepolymer is made...

Embodiment 2

[0048] The rocky slope at the entrance of the tunnel is ecologically restored using this rocky slope ecological restoration method. The height of the rocky slope is 4.2m, which specifically includes the following steps:

[0049] 1) Build the rocky slope into 6 ladder-like steps, the height of each ladder-like step is 0.8m, and the surface of each ladder-like step is inclined inward and has an angle of 5 degrees with the ground plane;

[0050] 2) After removing the crushed rock, inject viscose slurry into the cracks. The preparation method of the viscose slurry is: polyurethane prepolymer, cement, slaked lime, water and isopropyl triisostearyl titanate According to the ratio of 3:1:2:3:0.2, mix and stir in the mixing tank evenly to make a viscose slurry, let it stand for 1-2 hours to make the viscose slurry form a viscose slurry layer and a water layer, remove the water layer and stir again Made of viscose slurry; the polyurethane prepolymer is made of isocyanate, polyethylene ...

Abstract

The invention relates to an ecological restoration method for a rocky slope. The method comprises the following steps that the rocky slope is built into multiple ladder-like steps, and the step surface of each ladder-like step is inward tilted and has a 5-10-degree inclined angle with the ground; after broken rock is removed, viscose slurry is injected into cracks; at least one inserting hole is respectively drilled at two edges of the middle part of the step surface of each ladder-like step and is vertical to the ground; a support frame is installed on the step surface of each ladder-like step, and the support frame comprises a frame and two support pillars which are connected with two edges of the bottom surface of the frame and are respectively inserted into the inserting holes in the step surface; a planting frame is put on the support frame, and soil materials are put in the planting frame to plant vegetations; and the soil materials comprise a sand layer, a humus layer, a soil layer, a membrane layer and a fertilizer-soil mixing layer from top to bottom. The rocky slope is restored through the method, so that the construction strength and the construction capacity are greatly reduced, the fast restoration and greening of the exposed rocky slope are realized, and meanwhile, the safety and the stability of an ecological restoration body and the rocky slope are effectively increased.

Description

technical field [0001] The invention relates to a rock slope ecological restoration method. Background technique [0002] During the construction of road construction, municipal engineering or garden projects, the development of rocky mountains often needs to destroy the original ecosystem of the mountain, and clear the vegetation and surface to form exposed slopes. The exposed slope is not conducive to the harmony of the landscape, and because the slope has a large slope, the rock or soil of the slope is easy to lose. Especially after being washed and etched by rainwater, the rock or soil is relatively loose and prone to collapse accidents. Therefore, it is necessary to repair and green the slope and rebuild the slope ecosystem. However, rocky slopes are often mixed with more gravel or crushed rock, and the rocky slopes are hard and barren. When restoring the ecosystem, it is difficult to green construction and green vegetation protection. At the same time, the slope of r...
