Slope mixing forming ecological protection method

Abstract

The invention belongs to the technical field of slope protection and provides a slope mixing forming ecological protection method for solving the series problems that the damage recovery rate is high, and the protection efficiency is gradually reduced in the prior art. The slope mixing forming ecological protection method includes the steps that A, a temporary protection measure is set, wherein the temporary protection measure is established through a simple engineering structure in the engineering building stage and the initial operation stage; and B, a permanent protection measure is set, wherein after the temporary protection measure is established, an ecological vegetation planting forest is adopted for establishing the permanent protection measure to make the engineering operation stage achieve expected safety protection. The temporary protection measure includes a simple engineering structure, and the temporary protection measure is used for achieving a protection function before the permanent protection measure does not achieve the protection capability; and the permanent protection measure includes the ecological vegetation planting forest. The slope mixing forming ecological protection method is easy to maintain, the engineering quality and the ecological efficiency are balanced, meanwhile, better environment benefits are achieved, and the maintenance cost and the input cost are reduced to the maximum degree.

Description

technical field [0001] The invention belongs to the technical field of slope protection, and in particular relates to a hybrid ecological protection method for slopes. Background technique [0002] Rockfalls on slopes on mountainous roads generally have the characteristics of uncertain sources, wide-ranging generation points, sudden occurrence, difficulty in detecting and avoiding, and difficult or even impossible eradication. Disaster accidents caused by falling rocks occur frequently, which is a major issue for the safety of traffic and pedestrians below. Hidden dangers have caused great social pressure on the government and traffic authorities, and have also caused great distress to traffic technicians, so the prevention and control problems need to be solved urgently. [0003] Since the 1990s, the use of active and passive flexible protective nets to control slope disasters such as landslides and falling rocks has gradually developed into a common practice. The commonly...

Problems solved by technology

But practice has repeatedly proved that its shortcomings are very prominent, such as the source of falling rocks and the scope of protection are not easy to determine, resulting in protection projects that are neither economical nor effective

First, if the passive SNS protective net is used, not only the protection area on the facade is too wide, the engineering protection efficiency is low, and the economic benefit is poor, but also in the vertical section, because the ordinary protective net generally does not exceed 5m, rockfall is still very easy Crossing the net still causes disasters, even if the use of 2-3 protections still cannot achieve the purpose of greatly improving the protection effect; second, if a curtain-type SNS protection net is used, it is still difficult to identify the protection object, the project scale is too large, and the cost Third, if a passive retaining wall is used, the pros and cons are similar to those of a passive net, except for the difference in materials; if an active net is used, its effect is roughly similar to that of a curtain-type protective net

That is to say, the use of engineering structures to solve such disaster problems has a series of problems such as short service life, high overlap between damage period and protection period, high damage repair rate, and gradual decrease in protection efficiency. Moreover, it is not conducive to ecology and environmental protection. District construction is flawed

[0004] The reasons can be roughly summed up in four ways: the prevention and control measures at fixed positions are difficult to match and adapt to the development and changes of slope surface reconstruction; the management and maintenance are not enough to make it difficult to remove rockfalls in the net, and the protection effect will be more discounted in the later stage; The level spectrum is too wide, and the flexible net is difficult to adapt, so the structural columns are easy to be knocked over or bent, and the net surface is easy to be damaged; the height of the flexible net is low or the topography causes falling rocks to often cross the protective net and cause disasters, and the protective structure cannot meet the design. Effect

To sum up, there are some problems such as poor protection effect, high maintenance cost, and cumbersome post-management work.

In recent years, although the development and application of curtain protective nets have improved some defects of the active and passive nets, there are still deficiencies due to innate reasons, such as the matching problem between the protective energy level of the protective net and the energy level spectrum of falling rocks If it has not been resolved, then the problem of structural damage will also occur from time to time. In addition, it still cannot avoid tedious maintenance and repairs in the later stage, as well as emergency repairs after damage. and the effect is greatly reduced
