Anti-slip strengthening device construction method

Abstract

The invention relates to an anti-slip strengthening device construction method. The method comprises the following steps that geotechnical engineering reconnaissance is performed on an easily-sliding mountain to obtain rock stratum thickness information, mountain gradient information and earth surface elevation information to determine control point coordinate information of anti-slip piles when the anti-slip piles are arranged; drilling operation is performed at the corresponding position according to the control point coordinate information; the anti-slip piles are arranged in the drilled holes correspondingly, cement slurry is injected into the drilled holes, and the grouting pressure range in the grouting process is 0.6-0.8 Mpa; the adjacent anti-slip piles are connected through steel wire ropes to form a plurality of unit storage portions in an enclosing manner, and the unit storage portions are internally and fixedly provided with flexible grid meshes. The anti-slip strengthening device construction method is simple, construction efficiency is high, corrosion resistance is good, the construction cost is low, and the anti-slip strengthening device construction method is particularly suitable for application occasions where ionic rare earth resources are exploited with an in-situ leaching process and can meet the requirement for safe production of ionic rare earth mines.

Description

technical field [0001] The invention relates to the technical field of in-situ leaching and mining of ion-type rare earths, in particular to a construction method of an anti-skid reinforcement device. Background technique [0002] Rare earth is a non-renewable scarce resource, known as the "gold" of industry, and is widely used in new energy, new materials, biomedicine, aerospace, national defense, agricultural and environmental protection and other fields. In particular, ionic medium-heavy rare earths are irreplaceable raw materials for high-tech materials and cutting-edge technology products, and are extremely important strategic resources. At present, domestic ionic rare earth resources are mainly developed and utilized by in-situ leaching process. [0003] The main steps of the in-situ leaching process are: first, inject the leaching liquid into the ore layer through the liquid injection hole, make it contact with the rare earth ions adsorbed in the heterogeneous ore an...

Problems solved by technology

However, due to the traditional landslide prevention methods and devices, large and medium-sized construction equipment is required, the construction cost is high, and the construction process is relatively complicated, so it is not suitable for ion-type rare earth mines with weak infrastructure
