冻结法凿井虽是一种成熟的施工方法,但直到现在我国对冻结壁的形成和扩展情况及冻结壁的完整程度等还缺少直接准确的判断和检测手段,因而对冻结壁厚度是否已达到设计要求以及薄弱部分的具体位置的了解不够及时确切,往往不得不继续加强冻结,不仅浪费动力,而且常造成井筒内部冻实、开挖困难、延长工期、增加冻结成本等问题。本文介绍的关于井壁冻结过程的声波检测技术,将是解决上述问题的一种可靠而有效的方法。 Although the freezing method is a mature method of construction, but until now the formation and expansion of the frozen wall in China and the integrity of the frozen wall is still lack of direct and accurate means of detection and detection, and thus whether the frozen wall thickness has been reached Design requirements and the specific location of the weak part of the lack of timely understanding of the exact, often have to continue to strengthen the freeze, not only a waste of power, but also often caused by freezing inside the wellbore, excavation difficulties, to extend the duration and increase the cost of freezing and so on. The acoustic detection technology introduced in this paper about the borehole freezing process will be a reliable and effective method to solve the above problems.
