摘要
利用旋挖桩机施工速度快、成孔质量高、对岩土适用性较强的优势,借鉴水利工程冲抓套井回填黏土防渗墙施工工艺,采用旋挖套孔浇筑塑性混凝土形成防渗墙创新施工工艺,在大南山水库大坝防渗处理工程中实践应用并取得成效,对今后塑性混凝土防渗墙施工有一定的借鉴作用。
This paper introduces the features of fast construction speed,well-formed holes and strong applicability of rotary drilling rig.Based on the construction technology of backfill clay cutoff wall in water conservancy project,plastic concrete cutoff wall formed by rotary drilling technology has been applied in the seepage control project of Dananshan Reservoir and achieved results,which has certain reference for the construction of plastic concrete cutoff wall in the future.
