Background technique
With China's rapid development of economy, passenger and freight transportation demand is sharply increased, and in order to alleviate transport pressure, promotes region
It exchanges and merges construction, road and rail network construction is more accelerated, and more and more gos deep into hills and mountain area.In mountain area and mound
Mound area carries out needing to excavate Rock And Soil when road and rail construction, generates a large amount of bare side sloping, this has not only broken up Proterozoic
Looks have blocked the continuity of Regional Hydrologic, affect the local ecosystem, and easily cause the soil erosion, collapsing, landslide
And the disasters such as mud-rock flow, influence road and traffic safety.Therefore, it is necessary in road and rail design and construction side slope carry out
Necessary improvement and protection.
The slope of highway of early stage mostly uses engineering protection measure, improves side slope so that building stones, sand, cement etc. are main material
Stability, such as cement mortar smear reality, concrete spraying slope protection, prefabricated hexagonal cement brick, mortar flag stone, anchor and spray net technology,
Molding is fast, intensity is high, and early stage protection effect is good.But it has the following problems：On the one hand, this kind of protection face is unable to growing plant,
It can not restore local area ecological, visual impression public errand；On the other hand, protective materials and construction cost are high, and material therefor durability is poor,
Wind and frost sleet corrode and difference variation under the influence of, the case where later period will appear slope surface weathering, strength reduction, destroy again, protection
Service life, long and maintenance cost was not high.
In view of the above-mentioned problems, protecting slope ecology technology is come into being, the soil environment for constructing slope surface meets plant
Growth, and the protection on side slope surface layer is realized in interaction between plant (root system reinforced action) and rock, the soil body, greatly reduces side
Slope surface erosion, such technology can not only maintain side slope surface layer stability, and being capable of fast quick-recovery vegetation and ecological environment.
