Description

A kind of steep slope reinforcement protection device and laying method thereof

technical field

The invention belongs to the field of steep slope engineering, and relates to a steep slope reinforcement protection device and a laying method thereof.

Background technique

With the growth of population and the development of land resources, the problem of steep slopes has become one of the global geological disasters juxtaposed with earthquakes and volcanoes. In recent years, with the continuous expansion of the scale of human engineering activities and the limitation of engineering geological conditions in the site, geological disasters such as collapses, landslides, and debris flows caused by steep slope instability have brought huge losses to people's lives and property. The stability of steep slopes has become increasingly prominent.

For the stability of steep slopes, the existing treatment methods mainly fall into two categories: one is slope protection, commonly used measures include plastering such as mortar or composite soil, shotcrete, shotcrete, masonry stone retaining wall, anchor spraying slope protection, Anchor spray net slope protection, etc. Such measures are mainly used to protect the excavation of steep slopes from weathering, spalling, chipping, and a small amount of falling rocks. The second is the retaining structure, commonly used measures include retaining wall, anchor retaining wall, anti-slide pile and so on. Such measures not only have the function of protection, but also have the function of strengthening the slope body. The current commonly used engineering slope protection measures often pursue strength and efficiency too much, destroying the ecological nature and poor landscape effect. Moreover, with the passage of time, the concrete surface and the mortar surface will be weathered, aged, or even damaged, and the later renovation costs are high.

The above method can solve the problem of steep slope protection to a certain extent, but it also has its own shortcomings and deficiencies. The common disadvantages are: complex construction, high cost, long construction period, limitations in construction and maintenance, and high post-construction costs. In particular, in terms of reinforcement and protection of steep slopes, there is no highly recognized and cost-effective reinforcement and protection process.

Therefore, a new technical solution is needed to solve the above problems.
