| 摘 要： | 冲抓套井回填粘土防渗墙施工主要由造孔、回填和夯实三道工序组成，各道工序的控制原则是首先造孔要保证位置准、孔垂直，其次回填要均匀平正、分层填筑，最后夯实要选好夯锤、保证夯次和落距．另外，质量检测是冲抓套井回填施工保证质量的重要手段，要做到事前检测原材料的质量、过程检测每孔回填土的施工质量、以及完工后进行第三方检测的质量三控制原则．

| Abstract: | The open-bottomed well backfill engineering in impervious layer consists of hole-location,backfill and compaction.Precise position and vertical hole are the most important elements in hole-location,while uniform distribution and delaminating backfill are the main principles of backfill.When it comes to compaction,the hammer ram,the tamping quantity and distance should be ensured carefully.The quality inspection covers the quality assessing of the materials in advance,the backfill construction in working procedure and the third party inspection after the engineering,which is vital to the quality of open-bottomed backfill construction. |
