Expressway slope protection is generally realized through single reinforced concrete, mortar rubbles or other common methods; such common methods usually go against the long-term stability of expressway slopes and the harmony of surroundings while being prone to potential safety hazards such as landslides. I have invented a new method of utilizing waste water reclamation for landscape watering, afforestation, soil fixation and slope protection; such new method is based on the technology of integrating water conservation and fertigation; therefore, such new method can reduce the potential safety hazard of express slope landslides and thus reduce the water and soil loss.
The use of my invention technology for expressway slope protection can utilize water resources in an effective, cyclic and reasonable manner to supply good water and fertilizers for watering the vegetation on expressway slopes; the integration of spiral-wound pipe membrane with filter screen based on physical screening for water purification can efficiently separate heavy metals from waste water, meet the standard requirements for landscape water and be appropriate for expressway slope vegetation management and maintenance. My invention technology uses closed and spiral watering devices and is based on the outer surface threading design, so it can be easily inserted into soil and thus get to the roots of vegetation; the supply of organic water and fertilizers under rotation, grinding, pressurizing and high-efficiency arrangement treatment links to vegetation can effectively improve the ecological effect and natural harmony of greenery landscape along expressways; integrating the slope protection works with natural ecology is a new technology
