Embodiment Construction

[0024] The present invention will be described in detail below in combination with specific embodiments.

[0025] The invention relates to a protective method for planting grass with a turf skeleton on a subgrade slope in an alpine and high-altitude area. The steps include: leveling the slope surface → laying a turf skeleton → backfilling humus soil → sowing grass seeds → laying a fiber blanket → watering and maintenance. Specific steps are as follows:

[0026] (1) Slope leveling: Clean up and level the slope, cover with 10cm thick humus soil, and remove debris such as stones with a diameter greater than 5cm, so as to facilitate the combination of the turf skeleton and the slope, and provide conditions for the growth of native turf.

[0027] (2) Turf skeleton laying: ① Determine the position and laying method of the turf skeleton according to the height of the slope. For slopes below 3m, the turf is laid at the bottom of the slope, and the turf belt is set at about 60cm-100cm,...

Abstract

The invention relates to a alpine high-altitude area roadbed slope turf framework grassing protection method. The method comprises the following sequential steps of slope leveling, turf framework laying, humus soil backfilling, grass seed sowing, fiber blanket laying and watering maintenance. The method is suitable for the portion, where alpine meadow and alpine grassland are distributed as the main vegetation form, of the alpine high-altitude area, the blocky turf is used as the framework, the stored surface soil is stripped during filling and road construction, moreover, the grass seeds aresown, the three-dimensional net glassing and covering measures are adopted for assistance, maintenance is carried out during the construction period, the water-retaining and soil-retaining capacity ofthe three-dimensional net grassing technology, the soil retaining effect of the turf root system and the heat preservation and germination promoting functions of the covering measure are combined, moreover, the scientific maintenance measure is adopted for assistance, the slope soil loss is effectively controlled at the initial stage of slope vegetation growth, the water is effectively conserved,the good condition is provided for growing, germinating and root fixing of the vegetation, the growth time of slope vegetation is shortened, and the effect of the slope vegetation protection measureis achieved.

Description

technical field [0001] The invention relates to a flexible protection technology for roadbed slopes in high-cold and high-altitude regions, in particular to a method for protecting roadbed slopes by planting turf skeletons in high-cold and high-altitude regions. Background technique [0002] The Qinghai-Tibet Plateau is the highest plateau in the world, with a total area of ​​about 2.5 million square kilometers and an average altitude of over 4,000 meters. It is extremely difficult to grow vegetation, the ecological environment is extremely fragile, and it is extremely difficult to restore vegetation after destruction. Common turf with a thickness of 20-30cm usually takes thousands of years to form, and it is extremely difficult to restore surface vegetation after destruction. Turf plays a vital role in the ecological environment of the region. [0003] During the construction of infrastructure such as roads and railways, a large number of exposed slopes have been formed. T...
