Abrupt slope spray-seeding greening method

Abstract

The invention provides an abrupt slope spray-seeding greening method. The method comprises the following steps of clearing away loose stones and impurities on the surface of a slope; embedding grouting anchors in the abrupt slope, grouting for anchoring, inserting common anchors, and fixing by using reinforced belts; laying a geogrid, namely horizontally and longitudinally laying porous water pipes on the geogrid in a staggered way and laying an inverted filter on the geogrid and the porous water pipe until the inverted filter covers the porous water pipe; spraying a matrix and a seed mixture onto the inverted filter, or planting seedlings of plants in a matrix; laying a plant fiber net on the matrix and fixing by using a rattan net; laying a nonwoven geotextile on the rattan net; performing maintenance on plants, watering in an initial stage, performing drip irrigation in a later period, and removing the geotextile after the plants survive. According to the method, water and soil loss of the slope can be effectively prevented, the water-holding capacity of the laid green belt is high, the green belt is subjected to drip irrigation to save water resource, the slope can be greened in a short time, and the restored slope has a good greening effect and is stable in structure.

Description

technical field [0001] The invention relates to a steep slope spray seeding method, in particular to a steep slope spray seeding greening method using geogrids and geotextiles to fix substrates, and belongs to the technical field of ecological slope protection. Background technique [0002] The structural stability and ecological restoration of slopes are involved in the construction of high-speed railways, expressways and river management. These slopes are an important part of high-speed railways, highways and rivers. If they are not handled properly, they will fall, collapse, slide and even landslide, which will seriously affect the beauty of the environment, lead to soil erosion, and even cause traffic interruption, river silting, and accidents. Cause huge economic losses and personal safety. [0003] A slope with a large slope is a steep slope.

[0003] A slope with a large slope is a steep slope. Because of its large slope, rainwater often flows to the bottom of the slope without being absorbed by the soil, causing poor growth or even death of the plants on the top of the slope. The commonly used method of spraying on the slope is carried out directly on the slope. Thin spraying, for steep slopes, the thickness of the sprayed substrate is not large due to the lack of fixation, usually 5-12cm, the sprayed substrate is easily lost under heavy rain, and the substrate needs to be re-sprayed many times in the later stage, which is labor-intensive
