摘要
在堤防垂直截渗加固处理技术中,多头小直径深层搅拌桩水泥土截渗墙是近几年发展的新技术,这种截渗墙是由若干水泥土桩体搭接形成的。施工中各桩体间搭接的程度,决定墙体最小厚度,其中墙体最小厚度是一项重要质量指标。根据圆柱体相交几何原理,采用测定桩间距的方法,推求在任意深度下墙体最小厚度。
In the vertical cutoff strengthening processing technology for dike, multi head, small diameter, deep mixing pile cement soil cutoff wall is a new technology developed in recent years. This kind of cutoff wall is lap-jointed by some cement soil pile body. During the construction, the extent to lap-joint between each pile body determines minimum thickness of the wall, in which minimum thickness of the wall is an important index. According to the principle of cylinder geometric intersection, this paper calculates the minimum thickness of the wall at an arbitrary depth by the method of testing distance among piles.
