Highway soil slope flood damage prevention method

Abstract

The invention discloses a highway soil slope flood damage prevention method which includes steps of A1, piling; A2, planting shrub seeds at position which is 2-3cm lower than the ground of a slope; A3, laying local crop straws on the slope uniformly at the thickness ranging from 10cm to 15cm; and A4, covering with a net. After one or two years, the shrub seeds grow, the crop straws are decomposed completely to be a good organic fertilizer, and the organic fertilizer is absorbed and utilized by soil of the slope gradually and is an environment-friendly material. Willow or locust piles driven into the soil can grow and sprout at the probability of 80% at least during construction in spring or autumn, roots of the piles can grow and flourish gradually, then biological 'piles' and landscape 'piles' which grow strongly gradually are formed, and subsequent maintenance is almost omitted.

Description

technical field [0001] The invention belongs to the fields of traffic and construction, and in particular relates to a method for preventing and controlling water damage of road soil slopes. Background technique [0002] Before the mid-1980s, my country mainly focused on the construction of low-grade roads. Due to the small traffic volume, less deep digging and high filling, and little investment, protection projects were not considered as the main project of road construction. With the rapid development of highway transportation, the grade of highways is getting higher and higher, and the mileage of traffic is getting longer and longer. Since most roads are built in mountainous or hilly areas, road slopes have become an important part of road construction. Consequently, the number and scale of high and large slopes in highway construction increase, and the phenomenon of slope damage becomes more and more serious due to various reasons. [0003] Road slopes are generally di...

[0008] Three-dimensional vegetation net combined with vegetation slope protection technology: three-dimensional vegetation net combined with vegetation slope protection technology is a slope protection technology developed in recent years. It has the advantages of convenient construction, short construction period and good slope protection effect. It can be greened and beautified in a short time The side slope integrates the road with the surrounding environment and landscape, and is conducive to the restoration and maintenance of the ecology. The main problem is that the construction is relatively complicated

Under the premise of ensuring slope protection, in areas with poor slope stability, reinforcement measures can be taken for the slope protection of hexagonal hollow bricks to improve the stability of the slope. In order to prevent surface water from scouring and beautify the environment, hexagonal hollow bricks Planting grass and greening in the hollow position, like a honeycomb, has a certain ornamental value, but the cost is high, and it should be carefully selected for the slope protection of the second and above
