Problems solved by technology

[0003] One of the reasons: the soil of the excavated slope is poor, which is not conducive to the long-term growth of plants
Although the guest soil layer has certain fertility and soil activity, the guest soil layer is relatively thin, and its ability to supply nutrients and fertilizers is very limited. At best, it can only provide short-term fertilizers, which is not conducive to the long-term growth and development of vegetation.

Embodiment Construction

[0018] The implementation process of the present invention is as follows,

[0019] 1. After the slope to be repaired is leveled, a mouth-shaped pit 1 is excavated on the slope. The axis of the mouth-shaped pit 1 is perpendicular to the slope. The size of the pit is 300mm×300mm×200mm, and the depth is 200mm. The distance from the center of any mouth-shaped pit 1 in the center of the slope to the centers of the two adjacent pits laterally is 1500mm, the row pitch of the pits (pit center distance) is 1500mm, and two adjacent rows of mouth-shaped pits 1 are arranged in a staggered manner.

[0020] 2. Fill the multifunctional soil in the mouth-shaped pit. The preparation of the multifunctional soil is as follows: planting soil, urea, organic fertilizer and long-acting fertilizer are in mass ratio: planting soil 1, urea 0.01-0.03, organic fertilizer 0.1-0.2 and The long-acting fertilizer is 0.04-0.06, and the long-acting fertilizer is urea-formaldehyde fertilizer. That is, 100Kg pl...

Abstract

Disclosed is a novel method for constructing an ecological slope protection substrate, which pertains to the field of slope protection engineering, ecological restoration engineering and greening engineering. The construction process of the method of the invention is: first, leveling the slope surface need to be restored and excavating mouth-shaped pits on the slope surface, and then filling the mouth-shaped pits with multi-functional soil and finishing the construction of the slope protection substrate. The method for constructing the ecological slope protection substrate provided by the invention, by arranging the mouth-shaped pits on the slope surface, not only can change the status of soil impoverishment and the growth environment of vegetations, and provide essential fertilizers and nutrient substances for the sustainable growth of plants, but also can greatly increase the cohesive force between the guest soil layer and the fraction excavated, and increase the integral stability of the guest soil layer so as to effectively prevent the slope surface from integral damage by the continuous effect of rain. The method of the invention changes the mechanical characteristics and construction modes of the substrate and improves the present statuses of the poor stability and soil impoverishment of the substrate in the ecological slope protection.

Description

technical field [0001] The invention relates to an ecological slope protection technology applied to ecological slope protection projects, especially highways and railways, and focuses on the construction method of the slope protection base material. Background technique [0002] For the importance of the ecological slope protection of the expressway, people have already realized to some extent basically. At present, ecological protection projects for domestic highways can be seen everywhere. However, there are many cases of slope protection failure in the ecological slope protection of expressways in China, especially in arid or semi-arid areas with large slopes, where the supply of water and nutrients to the slopes is poor. The surface collapses and peels off frequently. In particular, slope collapse and spalling occur more frequently in ecological slope protection using soil spraying technology. Even if the slope is very gentle, once heavy rain occurs, the soil moisture...
