Description
Technical Field
The invention relates to a side slope restoration method, in particular to an ecological restoration method for an assembled wooden sash side slope.
Background
Due to the reasons of slope runoff, artificial construction and the like, a large number of bare soil slopes and rock slopes are formed, and water and soil loss and ecological environment imbalance are caused. The slope ecological restoration can keep water and soil, improve ecological environment and improve landscape effect, and has positive effects on protecting slope ecological system and maintaining slope stability. Traditional bank protection is restoreed and is mainly had grout or dry masonry bank protection, cast in situ concrete bank protection, precast concrete block bank protection etc.. The method has the disadvantages that the design and construction are only carried out from the stability of the side slope, the influence on the environment and the ecology is rarely considered, and the construction procedures of road beam shoulder concrete, mold casting and the like are required in the construction process, so that the construction requirement of any slope surface position is difficult to meet. The vegetation can be quickly formed on the slope by methods such as ecological bag slope protection, greening spray seeding and the like, but the vegetation type mainly comprises herbs, the diversity of the plants is poor, the construction process is complex, and the stability is low.
For example, publication No. CN101371638A discloses a method for greening a slope by using vegetation. The method comprises the steps of manufacturing an anti-corrosion wood frame by using an anti-corrosion wood board, manufacturing a geotextile bag with the size corresponding to that of the square anti-corrosion wood frame, filling a planting matrix in the geotextile bag, nailing the anti-corrosion wood frame on a slope needing vegetation greening in sequence by using a pre-fixing anchor rod, placing the geotextile bag filled with the planting matrix in the anti-corrosion wood frame, planting vine plants on the geotextile bag, and growing the vine plants to implement slope greening. The invention can be suitable for slope surfaces with any gradient; the material source is wide and cheap, and the pressure of economic cost is reduced; the operation is easy, the construction is simple, and the large-area popularization can be realized; the large-range green covering of the slope can be realized within 1-2 years. The invention expands the survival platform of the plants to the slope, and the planting mode of the wall painting fully exerts the characteristics of the cirrus plants, and because of the rich species of the cirrus plants, the diverse combination of the slope plants can build rich side slope landscape effect in a short period. This solution has the following problems: (1) almost all the procedures need to be finished on site, so that the operation is complex and the construction period is long; (2) only the lianas are planted, the diversity of the plants is poor, and the comprehensiveness of the covered plants is affected; (3) the anticorrosion material is added in the anticorrosion wood, so that the long-term rain wash is not beneficial to environmental protection and plant growth; (4) only adopt the stock to fix on domatic, do not really be fit for the domatic of high slope, also have the danger of stock inefficacy for long-term outdoor use.

(3) leveling the soil slope;
(4) paving a plurality of sash structure components on the slope surface and mutually connecting and fixing the sash structure components;
(5) fresh plant lops downwards penetrate through the sash structure assemblies and are driven into soil of the soil slope, and then the soil slope is watered and managed for at least 3 months at regular intervals until plants grow.
In the step (1), each side of the sash structure is made of raw wood or bamboo with the length of 1-1.5 m and the diameter of 50-100 mm.
In the step (2), the bag protection clamp is fixed in the upper and lower layers of sash structures through iron wires or long nails.
In the step (3), after the soil slope is leveled, square grooves are dug on the soil slope according to the size of the sash structure; and (4) paving a plurality of sash structure assemblies on the slope surface to enable the lower layer sash structure to be just embedded in the square groove and enable the lower surface of the protective bag to be in contact with soil of the soil slope.
In the step (3), the depth of the square groove is equal to the thickness of the lower layer sash.
In the step (5), the length of the fresh plant cut branches is 1-1.5 m, and the diameter is 4-6 cm.
In the step (5), the depth of the fresh plant cut branches into the slope soil is 0.5-1.0 m.
In the step (5), the fresh plant lops are taken from trees and/or shrubs which can form adventitious roots.
In view of the problems in the background art, the inventors made the following improvements: (1) the construction process is simplified, the steps (1) and (2) can be completed in a factory in advance, the inconvenience and complexity of site construction are saved, the labor amount is greatly reduced, and the construction period is shortened; (2) the sash structure adopts natural wood or bamboo, on one hand, the bamboo of the original wood absorbs less heat than concrete, and compared with concrete materials, the temperature of the slope can be reduced by 10-15 ℃ in summer, thus being beneficial to plant growth; on the other hand, the original (bamboo) wood rot is not needed to be preserved, and the nutrition is provided for the growth of the plants by skillfully utilizing the original (bamboo) wood rot; (3) grass seeds and soil are directly mixed in the protective bag without additional sowing, so that time and labor are saved; the protective bag is clamped by adopting a two-layer sash structure, so that the bag body can be effectively fixed and protected, the installation and the transportation are easy, the self weight can be increased, the friction force with soil can be improved, and the sliding risk can be reduced; (3) the sash structure components are fixed without anchor rods, and the adjacent sash structure components are fixedly connected; (4) the fresh plant lopping is driven into the sash structural component, the lower end of the fresh plant lopping goes deep into the side slope soil, the effect of supporting and fixing the sash structural component is achieved at the initial stage, the slope is enabled to form the intensive vegetation combined by arbor, irrigation and grass with different root system depths and different vegetation heights through maintenance at the later stage along with the growth of the new plant branches, the plant diversity is good, the slope can be rapidly stabilized, the function of fully covering the slope is achieved, and the effects of preventing water and soil loss and intercepting non-point source pollution are good.
Furthermore, after the soil slope is leveled, square grooves are dug in the soil slope according to the sizes of the sash structures, the lower layer sash structures are just embedded in the square grooves, the lower surface of the protective bag is in contact with soil of the soil slope, and therefore the stability of the sash structure assembly on the slope is greatly improved. On a large-gradient side slope, construction can be performed even if no anchor rod is fixed, and the anchor rod is easy to maintain and good in stability and reliability.
In conclusion, the method has the advantages of simple construction, short period, low cost and good plant diversity, can be used for construction at any position of the slope surface, effectively reduces the temperature of the slope surface, is beneficial to plant growth, can rapidly prevent and treat water and soil loss of the side slope, can effectively stabilize the slope surface, and is suitable for ecological protection of gentle slope surfaces.
