挂网客土喷播在岩质边坡复绿中的应用

Application of net hanging and soil spraying in greening of rock slope

挂网客土喷播一般用于坡率不大于1∶0.84的岩质、土质及岩土混合边坡的复绿,对于高陡边坡不适合,但高陡边坡的局部小平台存在喷播和复绿的条件。本文以徐州园博园西侧废弃采石宕口为研究对象,通过对采石宕口现状的分析,并结合国内外成熟的治理经验,针对本宕口的坡面形态,选取挂网客土喷播对岩质边坡的缓坡区和陡坡区的局部小平台进行复绿,为废弃采石宕口的地质环境治理提供技术参考。

Shotcrete with net hanging guest soil is generally used for re-greening of rock,soil and rock soil mixed slopes with a slope rate of no more than 1∶0.84(equivalent to 50°),which is not suitable for high and steep slopes,but there are conditions for shotcrete and re-greening on local small platforms of high and steep slopes.According to the slope shape of the quarry entrance,net hanging guest soil spraying is selected to regreen the local small platforms in the gentle slope area and steep slope area of the rock slope,so as to provide technical reference for the treatment of the geological environment of the abandoned quarry entrance.
