摘要
分析墙幕结合技术中存在的一些关键性问题,提出墙幕结合的布置形式和墙幕参数的确定方法;分析墙内预埋管技术的难点,提出了预埋管定位技术方案;分析了墙幕搭接的合理长度问题;详细叙述墙下钻孔和灌浆技术,分析了墙下灌浆容易铸管的原因并提出解决方法。
Some key problems of wall-curtain combination technology were analyzed. The layout patterns and the methods to determine parameters for wall-curtain combination were proposed. The difficulties in the embedded pipe technology were analyzed, and the location technology of the embedded pipes was put forward. The rational overlap length of wall-curtain was analyzed. The drilling and grouting technolngies under wails were introduced. The causes for casting pipes of grouting under walls were analyzed, and the relevant were proposed
