Problems solved by technology

The above methods can achieve the effect of slope protection and beautify the environment, but the construction and growth period is long, especially before the vegetation grows in the early stage, it cannot protect and stabilize the slope, and cannot stabilize the slope in a short period of time, which is easy to cause soil erosion At the same time, the slope-fixing components are made of flexible geotextiles, which are prone to aging and damage, and the slope-fixing effect is not good, and the roots of herbaceous plants are short, which cannot form species diversification in a short period of time, and it is difficult to form a natural succession of plant communities

Embodiment 1

[0038] Such as figure 1 The shown construction method flow chart of the present invention, the first step, cleans up, leveling the slope surface: adopt artificial removal of slope surface sundries, pumice, and knock off protruding rocks, make the slope surface as smooth as possible; to the neat and smooth rock slope surface Carry out excavation treatment to keep the slope surface rough and easy to bond with sprayed artificial soil. For the cave parts, use block stones or rubble concrete to fill up to the existing slope; the larger concave parts can be filled with artificial soil in plastic woven bags.

[0039] The second step is to install the planting board

[0040] The planting board is mainly used to stabilize the sprayed artificial soil and seedling substrate, so that it can be stably attached to the slope and connected with the slope to prevent it from sliding down. The material composition of the planting board: the planting board is composed of retaining strips, posit...

Embodiment 2

[0062] The difference between embodiment 2 and embodiment 1 is that in the second step of installing the planting board, the retaining bar is 500mm long, 70mm wide, and 10mm thick; the positioning reinforcement adopts a Φ12mm steel bar with a length of 30cm. I want to compare the length and width of the baffles in Example 1, which is easier to stabilize the substrate sprayed on the planting board; the row spacing of the planting board is controlled at 50cm. The positioning steel bar is driven into the slope at a depth of 20cm, and the specific depth is adjusted according to the geological conditions of the slope to ensure the stability of the planting board and the base material after spraying. There should be no overhead phenomenon between the planting board and the slope; the retaining strips of the planting board should be firmly bound with the positioning ribs, without tipping or loosening;

[0063] In addition, in the third step of laying steel wire mesh, the main anchors...

Embodiment 3

[0065]Embodiment 3 is identical with embodiment 1 other steps, and difference is: in the 5th step spray planting seedling-raising matrix, before adding shrub arbor seed and stirring, earlier seeds are soaked, and its soaking time and water temperature are as follows:

[0066] Seed Soaking Treatment

[0067]

[0068] The germination rate of the seeds soaked according to the method in the above table is about 85%. For some of the seeds whose shells are hard, the soaking time is long to soften the shells and make them easy to germinate. For the tender seeds themselves, a shorter soaking time can be used. It also plays a big role in softening the shell. The higher the water temperature, the easier it is to soften the shell.

Abstract

The invention relates to the field of cut slope protection construction, in particular to a fast construction method of rock slope protection. The method includes the steps of firstly, cleaning and leveling a slope surface; secondly, mounting a vegetation board; thirdly, paving a steel wire mesh; fourthly, spraying artificial soil; fifthly, spraying seedling substrate; sixthly, covering a protecting layer; seventhly, maintenance and management; wherein the seedling substrate is mixed by Lespedeza seeds, Magnolia multiflora seeds, crotalaria mucronata seeds, Robinia pseudoacacia seeds, amorpha fruticosa seeds and artificial soil. The method is fast in construction, vegetation can be restored rapidly, species diversity and natural succession can be formed in a short term, and natural environments can be beautified. Trees and shrubs are developed in roots and high in slope protection capability, a stable protection layer with certain strength can be formed on the slope surface in a short term, water and soil loss can be prevented, and slope stability can be guaranteed.

Description

technical field [0001] The invention relates to the field of cutting and slope protection construction, in particular to a rapid construction method for slope protection on rock slopes. Background technique [0002] For rocky slopes, traditional construction methods fall into the following two categories: [0003] The first type is rigid slope protection, that is, on the rock slope, masonry masonry masonry rubble wall, hanging net sprayed concrete or hanging protective net, etc., to seal and protect the slope. The above methods can achieve slope protection and prevent soil erosion, but the construction period is long and cannot restore vegetation and beautify the environment; [0004] The other is flexible slope protection, that is, planting climbing plants on rocky slopes, stretching net grass, geocell grass and planting bag grass, etc. The above methods can achieve the effect of slope protection and beautify the environment, but the construction and growth period is long...
