滚钟口水库除险加固工程多头水泥搅拌桩防渗工程质量控制

摘要

多头小直径深层水泥搅拌桩防渗墙是通过搅拌机械将地基土和固化剂强制搅拌，地基土与固化剂之间凝结有了一定厚度、强度和抗渗性能的连续桩体。这一新工艺的运用，水库坝体外坡土壤已由潮湿渐变为干燥，可有效解决坝体及坝基渗漏问题。详细介绍了多头水泥搅拌桩防渗工程质量控制指标及措施。%Multi-head, small diameter, deep agitation pile anti-seepage wall are formed between foundation soil and curing a-gent through forced mixing by agitating equipment, and featuring certain thickness, intensity and anti-seepage. The applica-tion of this technology makes damp soil outside reservoir dam dry, thus solve the seepage problems in dam and dam foun-dation. Quality control indexes and measures of multi-head agitation pile anti-seepage projects are discussed at length.
