Slope reinforcement and ecological repair technology taking iron tailings as aggregate

Abstract

The invention discloses a slope reinforcement and ecological repair technology taking iron tailings as aggregate. The slope reinforcement and ecological repair technology is characterized in that corematerials for slope reinforcement adopt the iron tailings and plant vetiver grass in company with reineckea carnea plants and are locked by anchor rods, and the multiple effects of sewage control, slope protection and greening are achieved; and the slope reinforcement and ecological repair technology comprises the following technological processes: (1) a slope surface is trimmed and a concrete retainer is constructed; (2) bottom layer base cloth and a PE anti-seepage film are laid; (3) construction materials are prepared; (4) construction is performed and PC drainpipes are laid; (5) the anchor rods are used for reinforcement; (6) the plants are planted; and (7) professional curing management is carried out. The iron tailings are utilized as the aggregate for the slope protection, and reineckea carnea is planted, so that an iron tailing resource utilization approach is explored, waste materials are recycled, land pollution can be reduced, and an ecological value is produced at the sametime; and the vetiver grass acts as a reinforcement material, so that the skid resistance of a side slope is improved greatly.

Description

technical field [0001] The invention relates to the fields of civil engineering and ecological restoration, in particular to a slope support structure and vegetation slope protection technology using iron tailings as aggregates in engineering excavation and construction. Background technique [0002] Iron tailings are currently the main waste generated during metal mine processing. In the northern and southwestern metal mining areas of my country, the vegetation destruction and water and soil pollution caused by mining are shocking. It is urgent to strengthen the control of the source metal mining areas, especially the iron tailings. At present, the comprehensive utilization rate of iron tailings in my country is only 7%, and the treatment of iron tailings is mainly concentrated in three aspects: one is mainly to accumulate, and sometimes build tailings storage, but a large amount of accumulated tailings not only occupies land, Destroy the soil, and seriously damage the natu...

Problems solved by technology

However, the current treatment of iron tailings still has the characteristics of low comprehensive utilization rate and high pollution rate. How to better replace it with building materials, use nearby materials, turn waste into treasure, reduce production costs, and resource utilization is urgently needed

[0003] In terms of soil slope treatment, the existing technologies all use traditional technical measures such as concrete, masonry retaining walls or anchor piles, and anchor rods (anchor cables) + grid beams are currently the most commonly used methods for slope support , that is, it is composed of lattice beams installed on the slope surface and anchor rods (anchor cables) installed in the slope body. The anchor rods (anchor cables) are anchored on the lattice beams, and grass can be planted in the lattice beams, but the plants planted cannot It is well adapted to the absorption of pollution elements in iron tailings, and sometimes the soil fixation ability is relatively poor, so the selection of plant species has important ecological value for slope reinforcement
