Ecological slope protection structure of road cutting side slope and construction method

Abstract

The invention discloses an ecological slope protection structure of a road cutting side slope. The ecological slope protection structure of the road cutting side slope comprises a side slope body, a framework beam fixed to the side slope body, seedling growing modules and an irrigation system; the framework beam comprises a plurality of cross beams and longitudinal beams which are staggered and fixed transversely and longitudinally; a plurality of planting cells provided with base material modules are defined by the cross beams and the longitudinal beams which are staggered transversely and longitudinally; each base material module comprises a planting pit excavated in the position of the corresponding planting cell, a protecting net covering the planting pit and fixed to the framework beam, and a nutrient medium arranged in the planting pit; a plurality of seedling growing modules are arranged in each base material module; each seedling growing module comprises a nursery stock and a planting pot in which the nursery stock is planted; and each planting pot comprises nutrient soil filled in the planting pot, a degradable base and a degradable pot body fixed to the base. Construction is convenient, the nursery stocks are irrigated fully with natural rainfall, the nursery stocks are firstly cultivated and then are transplanted in a container seedling growing manner, it is guaranteed that the nursery stocks have a good survival rate, good economic and technological benefits are achieved, and it can be guaranteed that the greening project is effective for a long time.

Description

technical field [0001] The invention belongs to the field of highway engineering, and in particular relates to an ecological slope protection structure and a construction method of a highway cutting side slope. Background technique [0002] With the development of the national economy, highway construction plays an increasingly important role in the national economy. However, due to the high-quality and high-standard requirements of the expressway and the particularity of the construction, it will inevitably cause a certain degree of damage to the natural environment and ecology. Therefore, how to do a good job in transplanting seedlings on the cutting slope of the expressway has become particularly important. [0003] In the construction of expressways, large-scale excavation formed more exposed cutting slopes, resulting in the disappearance of the original plant ecological environment, the soil structure of the cutting slopes was destroyed, and the effective nutrients were...

Problems solved by technology

However, the single green planting leads to low survival rate and poor greening effect, while the plant protection combined with engineering forms requires a large project investment, and as time goes by, the weathering of rocks, aging of concrete and corrosion of steel bars will make the engineering effect more and more serious. getting worse
