龙井水库大坝加固设计与施工概述

SUMMARIZE THE REINFORCING DESIGN AND CONSTRUCTION OF THE LONGJIN RESERVOIR DAM

介绍在垂直面上组成连续的防渗体，处理土坝渗漏的设计与施工方法．即在水上坝体采用冲抓钻套井回填粘土心墙，在水下坝体和坝基砂卵石层采用高压喷射灌浆成墙，在基岩部位采用水泥帷幕灌浆的方法．这种大坝渗漏处理的方法，技术可行，施工方便．经济合理，效果显著．

This paper introduce the design and construction method of dealing with the seepage of earth dam which make up the antiseepage wall on vertical plane. Use churn and grab, open-bottomed well, backfill the clay core on the dam body over water. Use the high-pressure grouting to make up the wall on the dam body under water and the sand gravel layer of dam foundation. Use the cement grout curtain on the bedrock. The method of dealing with dam seepage is reliable on technology, convenient on construction, reasonable on economy, notable on effection.
