大坝围堰防渗墙的施工技术

Construction Technology of Cutoff Wall of Dam Cofferdam

文章对工程概况分析后,对大坝围堰防渗墙施工难点和处理方法实行研究,对大坝围堰防渗墙施工技术进行探析,旨在联系大坝围堰防渗墙施工情况、需要,选择适合的施工技术处理,比方说:超深钻孔、陡倾岸坡嵌岩、接头拔管等施工技术。因工程存在一定的安全隐患,所以需要工程项目借鉴以往成功经验,在施工前做好相关预控工作,以此充分发挥出施工技术的应用价值,提高大坝围堰防渗墙整体施工质量。

After analyzing the general situation of the project,this paper studies the construction difficulties and treatment methods and analyzes the construction technology of the cutoff wall of the dam cofferdam. The study and analysis aim to select the appropriate construction technology( such as ultra deep drilling,rock socketed in steep bank slope,joint pipe pulling,etc.) according to the construction situation and needs of the cutoff wall of the dam cofferdam. Because there are some potential safety hazards in the project,it is necessary for the project to learn from successful experience in the past to perform relevant pre control work before construction. In order to give full play to the application value of construction technology and improve the overall construction quality of cutoff wall dam cofferdam.
