Method for landscaping micro-seepage moisture-preserving maintenance along high-speed rails

Abstract

The invention discloses a method for landscaping micro-seepage moisture-preserving maintenance along high-speed rails. An interchange water accumulation device which comprises a road shoulder drainageditch, slope drainage ditches, an apron slope, a slope bottom drainage ditch, an impurity filter and a first water cellar is constructed along the high-speed rails, or a micro-seepage moisture-preserving water supply device which comprises a road shoulder drainage ditch, slope drainage ditches, an apron slope, a slope bottom drainage ditch, an impurity filter, a controller, a liquid level meter,a road shoulder water supply pipe, a soil humidity sensor, a second water cellar and a micro-seepage moisture-preserving pipeline network is constructed. Rainwater is gathered and stored in the watercellar through a drainage facility; when rainwater is not available, water is transported and injected into the water cellar and can be directly pumped for irrigation, or, the controller controls a water pump to supply water according to signals sent by the soil humidity sensor, and micro-moistening irrigation is realized by seepage through the micro-seepage moisture-preserving pipeline network. The maintenance method has advantages that water for normal maintenance of vegetations can be guaranteed, the green plant survival rate of high-speed rail sections can be guaranteed, and influences onroadbed stability and traffic safety are reduced to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of greening and ecological restoration and maintenance of railway sections in arid, semi-arid and desert areas, and relates to a method for greening along high-speed railways with micro-osmosis, moistening and maintenance. The maintenance method of the present invention can also be used for rainwater collection and intelligent water supply maintenance for green plants in engineering applications such as road greening, slope greening, mine ecological restoration, and desertification prevention and control in the region. Background technique [0002] Desertification is a natural or unnatural phenomenon in which soil productivity is reduced or lost due to drought and less rain, vegetation destruction, strong wind erosion, water erosion, soil salinization, etc. In the desert area, the ecological type is single, the topography is complex, lack of water and rain, drought in ten years, strong wind and sand, excessi...

AI Technical Summary

Problems solved by technology

However, the longitudinal length of the railway line is too large, and there is no groundwater for irrigation along the desert area, and the distance from the water source is too large, which cannot meet the requirements of energy conservation, emission reduction and effect reflection in vegetation restoration and desertification prevention and control along the railway line.

In addition, in arid or semi-arid areas, in addition to low rainfall, coarse-grained embankment fillers have low water content and low nutrients, which are basically not suitable for plant survival and growth. Although micro-moist irrigation technology has the effect of saving water, it is mostly concentrated in patchy crop fields, and there is basically no research and application experience for linear roads, especially railways.
