Comprehensive prevention and control system applied to gravel soil side slope
The invention belongs to the technical field of geotechnical engineering, and discloses a comprehensive prevention and control system applied to a gravel soil side slope. According to the comprehensive prevention and control system, the good slope anti-seepage effect is achieved by burying drainage blind pipes and rapid drainage pipes in a slope surface layer soil body, arranging an intercepting ditch at the top of the slope, arranging a drainage channel at the foot of the slope and performing planting and greening on the slope surface, and the influence of surface water infiltration such as rainfall on the slope stability is reduced; after spring type spiral steel bars are put into pile holes, concrete doped with an expanding agent is poured into the pile holes to form miniature anti-slide piles, prestressed anchor cables are arranged to improve the shear strength of the side slope, and the stability among a potential sliding surface upper landslide mass, a potential sliding belt anda lower stable soil mass is enhanced; a plain concrete retaining wall is arranged at the foot of the slope to support the side slope, and a deep drainage pipe is drilled in the concentrated seepage area to effectively cut off the concentrated seepage, and water is collected and guided out of the slope; and finally, the anti-seepage drainage and reinforcement effects on the side slope are remarkable, and compared with traditional electro-osmosis drainage, energy consumption is reduced, economic benefits are remarkable, and operability is high.
本发明属于岩土工程技术领域，公开了一种应用于碎石土边坡综合防治体系，通过在坡面表层土体埋设排水盲管和急流排水管、坡顶设置截水沟、坡脚设置排水渠、坡面种植绿化的方式达到良好的坡面防渗效果，减小降雨等表面水入渗对边坡稳定性的影响；通过桩孔内放入弹簧式螺旋钢筋后，在桩孔内浇筑掺杂有膨胀剂的混凝土形成微型抗滑桩，并设置预应力锚索以提高边坡抗剪强度，增强潜在滑动面上部滑坡体、潜在滑动带和下部稳定土体之间的稳定性；在坡脚设置素混凝土挡墙支持边坡，并在集中渗流区钻设深层排水管有效截断集中渗流并将水分收集并导出坡外；最终，对边坡防渗排水与加固效果显著，与传统电渗排水相比节约能耗，经济效益明显，操作性较强。
