Method for ecological protection of loess slope by root system combined with frame tension belt

Abstract

The invention provides a method for ecologically protecting the loess slope through combination of a root system and frame tie bar belts. Lattice network type water discharging and storing grooves are constructed in the slope surface of the loess slope, anchor rods perpendicular to the loess slope are embedded in the water discharging and storing grooves at certain intervals, the top ends of the anchor rods are exposed out of the slope surface, the lower ends of the anchor rods penetrate a surface layer where inundating is likely to happen (a soil layer prone to being wetted and permeated by rainwater) to be anchored into an inner layer, hard to inundate, of the loess slope, a beam attached to the slope surface is fixed between the top ends of every two adjacent anchor rods, and a lattice network type frame is formed on the slope surface; plants with the developed root systems are planted in the water discharging and storing grooves at certain intervals, and the corresponding tie bar belt vertically penetrating the surface layer, prone to being inundated, of the loess slope is implanted between every two adjacent plants, the upper ends of the tie bar belts are tightened, bundled and fixed to the beams, and the lower ends of the tie bar belts are deeply implanted into the inner layer, hard to inundate, in the loess slope, wherein the tie bar belts have the tensile strength and water absorbing and retaining characters. According to the method, the loess slope can be ecologically maintained, and meanwhile the problem of water and soil losses is solved.

Description

technical field [0001] The invention relates to the technical field of water and soil loss and slope control engineering, in particular to a method for controlling water and soil loss of loess slopes by adopting an ecological protection method of root system combined with frame tension belts. Background technique [0002] Soil erosion is very serious in our country, especially in the loess area of ​​Northwest my country. Water and soil erosion control involves grain production and arable land security and traffic safety. Water and soil loss control is a long-term important task in national land construction. Water and soil loss is mainly slope water and soil loss, and slope water and soil loss control is the difficulty and the top priority in water and soil control. In order to control slope water and soil loss, people have developed a variety of effective control methods, such as sowing grass seeds on the slope surface, laying turf, hydraulic spraying grass planting, three...
