Reinforcing and anchoring ecological restoration system for high and steep waste slag side slope of wind power plant in mountainous area

Abstract

The invention discloses a reinforcing and anchoring ecological restoration system for a high and steep waste slag side slope of a wind power plant in a mountainous area. The system comprises a slope surface reinforcing soil fixation structure arranged on a waste slag slope surface, a side slope drainage structure, a bottom blocking structure and a slope surface vegetation recovery structure. The slope surface reinforcing soil fixation structure comprises a reinforcing net and a plurality of baffles, and the reinforcing net and the baffles are fixed to the waste slag slope surface through main anchor rods and U-shaped nails. The side slope drainage structure comprises an intercepting ditch and a drainage ditch, the intercepting ditch is arranged at the top of the waste slag side slope, and the drainage ditch is connected with the intercepting ditch. The bottom blocking structure comprises a retaining wall arranged at the bottom of the waste slag side slope. The high and steep waste slag side slope of the wind power plant in the mountainous area has the growth conditions of general tree-grass and shrub-grass, it is ensured that a certain ecological restoration effect can be achieved in a short period, meanwhile, the requirements for long-term stability and water and soil loss prevention of the high and steep waste slag side slope of the wind power plant in the mountainous area can be met, and therefore the technical level limitation of traditional water and soil conservation governing of the high and steep waste slag side slope of the wind power plant in the mountainous area is broken through.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration and treatment of high and steep slopes, and in particular relates to an ecological restoration system for reinforcing and anchoring high and steep spoil slopes of wind farms in mountainous areas. Background technique [0002] At present, for mountainous, hilly and plateau grassland areas, especially most wind power projects developed in mountainous areas in Southwest China, due to the steep original terrain of the wind farm area, tight construction period and lack of effective control during the construction process, most of the wind farm wind farm area, The dregs excavated from the original high and steep slopes in the road area are only discarded on the spot or dumped along the road. There are many high and steep dregs and slopes, which destroy the local surface vegetation and cause serious soil erosion and Ecological damage. [0003] For the high and steep spoil slope formed dur...

Problems solved by technology

[0011] The purpose of the present invention is to provide a high and steep spoil side for wind farms in mountainous areas in view of the common problems of poor applicability, high construction difficulty and high treatment cost in the high and steep spoil slope areas of mountainous wind farms in traditional slope water and soil conservation treatment methods. Slope reinforcement and anchoring ecological restoration system; make the high and steep spoil slopes of mountainous wind farms have general arbor and grass growth conditions, ensure a certain ecological restoration effect in a short period of time, and at the same time meet the needs of high and steep spoil slopes in mountainous wind farms Long-term stability and soil erosion prevention and control requirements, so as to break through the technical level limit of traditional water and soil conservation management of high and steep spoil slopes in mountainous wind farms
