Multi-layered and multiporous ecological barrel for protective slope ecology and method for ecologically restoring and greening side slopes

Abstract

The invention relates to a multi-layered and multiporous ecological barrel for protective slope ecology and a method for ecologically restoring and greening side slopes, which are applied to ecological restoration and greening projects of rocky side slopes and hard side slopes. The ecological barrel is a double-layered hollow pipe in which water holes with different sizes are dilled, a cushioning layer which is formed by organic compressible material is filled between an outer barrel and a hole wall, water-absorbing material is filled up between the two layers of barrels, mixed substrate which is suitable for plant growth is placed in the inner barrel, and the ecological barrel is put into a hole of a slope surface, and can ensure the normal growth of a bush or a climbing plant. The invention sufficiently exerts the respective advantages of the multi-layered and multiporous barrel and the ecological substrate; the invention has the characteristics of little slope surface disturbance, convenient construction, little construction load and the like; an environment suitable for the growth of plants is created for the exposed slope surface, and moreover, the adverse effect of root expansion on the slope body can be reduced to the max.

Description

technical field [0001] The invention belongs to the field of ecological restoration engineering and greening engineering, and in particular relates to a new slope protection ecological multi-layer porous ecological cylinder, and the application of this ecological cylinder to carry out ecological restoration on rocky slopes where vegetation is difficult to grow or on hard slopes where projects are implemented , Greening, realize slope vegetation growth and long-term greening, and improve slope landscape. Background technique [0002] In hydropower, transportation, municipal and mining projects, due to construction excavation, a large number of exposed rock slopes are formed, and some slopes are protected by shotcrete, masonry and other projects to form hard slopes. Due to the lack of vegetation growth conditions and poor ecological environment on these rocky slopes and hard slopes, the demand for slope landscape effects has not been well resolved for a long time.

Due to the lack of vegetation growth conditions and poor ecological environment on these rocky slopes and hard slopes, the demand for slope landscape effects has not been well resolved for a long time

[0003] The ecological restoration of vegetation concrete slopes has made some achievements in the ecological protection of rocky slopes, but due to the limited thickness of the base material, it is not conducive to the long-term growth of shrubs; also restricted
