Novel ecological slope protection substrate building method

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 needing restoring, excavating mouth-shaped pits on the slope surface, 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 used in ecological slope protection projects, especially highways and railways, and the focus is on the construction method of slope protection substrates. Background technique [0002] People have basically realized the importance of ecological slope protection of expressways. At present, ecological protection projects of domestic highways can be seen everywhere. However, there are many cases of failures in ecological slope protection of highways in China, especially in areas with large slopes, arid or semi-arid areas, where the supply of water and nutrients to the slopes is poor, and under natural conditions, lawn degradation occurs, and slopes are degraded. The face collapses and peeling often occurs. In particular, the use of spraying technology for ecological protection of the slope surface collapses, and spalling occurs more frequently. Even if the slope is very slow, the soil moisture...

AI Technical Summary

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.
