Ecological protection method for high steep side slope

Abstract

The invention relates to an ecological protection method for a high steep side slope. The method mainly comprises the steps of slope surface treatment, concrete shotcrete and rock bolt support, vegetating hole arrangement, net spreading, spray material preparation, granule spray sowing, maintenance, management, and the like. In the method, guest soil materials such as humus loam rich in organic matters and clay are utilized to undergo a granule reaction after mixed with a granule agent at the moment of spray sowing so as to form a greening template which has the same high order granule structure as natural soil and strong erosion resistance and can suppress water and soil loss. After a diversified mature plant community which is in harmony with surrounding vegetation environment is formed, the slope surface can be protected, which can effectively resist diseases and insect pests and maintain the ecological balance. Post maintenance management and expenses can be saved. All used materials can be naturally degraded, have no pollution to the environment and can purify air and beautify the environment. Equipment of the method does not need to be hung on the slope surface for construction, and spray sowing operations are carried out only below the slope surface, thus the method has high construction speed and safety. The method is suitable for slope surfaces which are difficult to green, and the like, such as various high steep and unstable slope surfaces, bare slope surfaces having high greening expected values, and the like.

Description

technical field [0001] The invention relates to the field of slope management, in particular to an ecological protection method for high and steep slopes. Background technique [0002] Ecological construction and environmental protection are hot topics of common concern to human beings in the 21st century, and they are also focal issues that governments and people around the world are making unremitting efforts to solve. The inconsistency between the rapid development of basic construction and the ecological environment has led to the ecological destruction of the environment on which human beings depend for survival. At the same time, it has also restricted the sustainable development of social economy and constituted a threat to human survival and social development. Therefore, taking into account project development and environmental protection is a major issue for sustainable economic development. Reasonable utilization of resources, environmental protection, and beautif...

Problems solved by technology

For example, plants cannot grow in bare places due to landslides and over-development, because the topsoil containing the nutrients and water needed for plant growth peel off, and the inorganic non-nutrient soil is exposed so that plants cannot grow

For slopes greater than 1:0.5, rocky slopes with poor lithology, low strength, and easy weathering; or hard rock formations, but are severely weathered, have well-developed joints, and are easily affected by natural stress, resulting in large-scale fragmentation. and rocky slopes with local small-scale collapses and falling rocks; or rocky slopes caused by blasting construction, resulting in a large number of over-explosions, the scope of damage goes deep into the interior of the slope, the slope rocks are broken and loose, and rockfalls and collapses are prone to occur. Slope stability cannot be ensured only by vegetation engineering, prefabricated concrete grid or plastic mesh plus seeding engineering, etc.

In order to ensure the stability of the slope, engineering measures such as sprayed concrete surface waterproofing or retaining walls and (hanging net) anchoring works can be used to solve the problem, but the defect of these methods is that they cannot protect the ecological environment and beautify the landscape
