Description

Side slope scour prevention structure Technical Field The utility model belongs to the field of protection of open pit side slopes, and particularly relates to a side slope scour prevention structure. Background Some surface mines are located throughout the year in a rainy season and a dry season, wherein 5 months to 10 months are rainy seasons, during which rainfall is almost daily, and heavy rain is frequent. The area is distributed with a large number of open-air mining pits, has the characteristics of poor slope lithology and weak rock soil such as a large number of fourth-series soil, weathered dolomite, siltstone, and smooth stone layer, is easy to cause rock soil loss under the flushing of rainwater, and even forms large gullies and slumps. Most of the traditional treatment modes are post-slope cutting and load shedding, huge funds are often needed to be invested, and the safety of production operation is a great threat. In addition, some projects in China adopt a method of grouting rubble or concrete to protect ditches and side slopes, but the cement cost of congo (gold) and other countries is far higher than that in China, the economy is unreasonable, and the difficulty and risk of similar construction on high and steep side slopes are also larger. Meanwhile, the traditional technical means have limited water flow guiding and slope protecting effects, and the hidden danger of slope instability is difficult to eliminate fundamentally. For example, patent CN103061327B adopts a counter slope and barrier technology, but it is mainly aimed at the dumping site, and the barrier has limited anti-scour capability. Patent CN101456789a, although enhancing slope stability to some extent, is complex and costly to construct. The limitations of these traditional approaches highlight the importance of innovative protection techniques. Disclosure of Invention The utility model aims to provide a side slope scour prevention structure, namely a double protection structure of transverse ditch protection and longitudinal slope protection, so that the scour hazard of rainwater to a weak side slope is fundamentally reduced, the side slope slump risk is reduced, and the production safety of an open-air pit in a rainy season is improved. The utility model provides a side slope scour prevention structure, which comprises: the horizontal water guide ditch comprises a horizontal main water ditch, a plurality of lateral water guide ditches connected with the horizontal main water ditch and distributed at intervals, a slope water guide ditch positioned on the slope and connected with the lateral water guide ditches, and And the longitudinal slope protection comprises a protective layer. In one embodiment, the protective layer is a multi-layer material layer. In one embodiment, the protective layer is a bilayer material layer. In one embodiment, the width of the transverse main ditch is 0.3-0.8 m, the depth is 0.3-0.8 m, and the gradient is 0.1% -0.5%. In one embodiment, the lateral water guide channel has a width of 0.5-1.0 m, a depth of 0.5-1.0 m, and a slope of 0.2% -0.8%. In one embodiment, the slope water guide channel has a width of 0.5-1.2 m and a depth of 0.2-0.5 m. In one embodiment, the protective layer includes a first protective layer and a second protective layer overlying the first protective layer. In one embodiment, the first protective layer is a waterproof geotextile layer and the second protective layer is a geotextile layer. In one embodiment, the second protective layer has a larger area than the first protective layer. In one embodiment, the first protective layer and the second protective layer are secured by staples. The utility model provides a side slope scour prevention structure, namely a double protection measure of transverse ditch protection and longitudinal slope protection, which has simple construction and reliable process, can fundamentally reduce the scour hazard of rainwater to weak side slopes, reduce the risk of side slope collapse, improve the production safety of open-air mining pits in rainy seasons, and save the cost of slope cutting and load reduction.
