Embodiment 1

[0058] The construction season is summer, and the site is in Wuhan, Hubei.

[0059] The slope angle is about 45°, the height is 3m, and the width is 20m. First lay a layer of bricks on the slope, and then cement the joints to simulate the rocky slope. Choose Ф14 anchors (length 40cm), the anchor rod needs to leak 10cm, and the distance between anchors is 1m×1m. The anchors at the top of the slope (with a specification of Ф14 and a length of 50cm) are densely laid out and slightly inclined (the included angle with the slope is 50°). Then lay galvanized chain link fence from top to bottom (the specification is Ф14, the mesh is 5×5cm), and the meshes and the joints with the anchors are tied firmly with iron wires (the specification is Ф16). The upper mesh is kept 8cm away from the slope, and the lower mesh is close to the slope.

Abstract

The invention discloses a rapid ecological restoration method for rock-soil side slopes, and relates to the field of ecological management for the rock-soil side slopes. The rapid ecological restoration method includes: (1) cleaning a rock-soil side slope; (2) paving a high-tensile net; (3) preparing basic materials for vegetation growth; (4) allocating vegetation, mixedly planting seeds and grass blades of shrubs and herbage plants endurable to draught and infertility and selecting rock-soil side slope protective Bermuda grass blades; (5) subjecting the vegetation to spray-planting; and (6) maintaining and managing. Since the rock-soil side slope protective Bermuda grass blades are selected to protect the rock-soil side slopes, the rapid ecological restoration method is efficient and rapid; the basic materials for the vegetation growth are easy to obtain, simple to prepare, scientific to prepare, capable of effectively meeting requirements on nutrient and moisture of the vegetation, beneficial to flourishing and long-term growth of the vegetation and the like; and the herbage plants and the shrubs endurable to draught and infertility are selected as the vegetation to be planted mixedly, so that the rapid ecological restoration method is good in landscape allocation effect. The rapid ecological restoration method is applicable to ecological restoration in earth-rock mountain regions, and is particularly beneficial to stability of eco-fragile regions with bare rocks.

Description

technical field [0001] The invention relates to the field of ecological management of rock and soil slopes (rock slopes and soil slopes), in particular to a rapid ecological restoration method for rock and soil slopes. Background technique [0002] In recent years, in the construction of water conservancy, highways, railways and mines, due to the long construction routes and large quantities of earthwork excavation and filling, the original vegetation has been seriously damaged, resulting in a large number of exposed soil slopes or rocky slopes. It is difficult or takes a long time for similar slopes to restore the ecological balance by nature's own strength; especially for rocky slopes, it is difficult to restore, which has exacerbated the deterioration of my country's already fragile ecological environment. Therefore, the development and improvement of slope vegetation protection technology It is of great significance to the construction of ecological environment in our coun...
