Anti-seepage treatment method for collapsed accumulation body
The invention discloses an anti-seepage treatment method for a collapsed accumulation body, relates to the field of anti-seepage engineering, and solves the problems that gaps of arc block stones in the collapsed accumulation body are large, underground water flows, and if grouting is directly carried out, an anti-seepage wall cannot be formed. According to the technical scheme, the anti-seepage treatment method for the collapsed accumulation body comprises the steps that firstly, a construction platform is formed on the surface layer of the collapsed accumulation body, the position of an anti-seepage wall is determined, and a drilling position is marked; secondly, drilling holes in the drilling positions, filling the drilled holes with gravel sand, vibrating the drilled holes, and filling gaps between the drilled holes and the collapsed accumulation body with the gravel sand in a manner of circularly drilling and filling the drilled holes with the gravel sand; and finally, drilling is conducted on all the drilling positions again, grouting is conducted, and the complete diaphragm wall is formed. According to the method, the gravel sand is filled into the drill hole and vibrated, gaps in the collapsed accumulation body are sealed, the flow speed and flow of underground water are reduced, after grouting, the gravel sand and grout are well combined, and the ideal seepage-proofing effect is achieved.
本发明公开了一种崩塌堆积体的防渗处理方法，涉及防渗工程领域，解决崩塌堆积体内孤块石的间隙大并存在地下水流动，若是直接进行注浆不能形成防渗墙的问题。本发明采用的技术方案是：崩塌堆积体的防渗处理方法，先在崩塌堆积体的表层形成施工平台，确定防渗墙的位置，并标记出钻孔位；其次，对钻孔位进行钻孔，向钻孔内填入碎石砂并进行振捣，通过循环钻孔并填入碎石砂的方式，使钻孔以及崩塌堆积体的间隙填满碎石砂；最后，对各个钻孔位分别重新钻孔并进行注浆，形成完整的防渗墙。本发明在钻孔内填入碎石砂并进行振捣，封闭崩塌堆积体内的间隙，降低地下水的流速和流量，注浆后，碎石砂与浆液较好地结合，达到了理想的防渗的效果。
