超声波法在地下连续墙成槽质量检测中的应用

Application of Ultrasonic in the Quality Inspection of the Groove of Diaphragm Wall

地下连续墙是深基坑和地铁工程中常用的一种支护结构,其成槽质量直接关系到连续墙墙体的质量,采用超声波法在地下连续墙施工过程中对其成槽的槽宽和垂直度进行检测,可有效保证成槽质量。本文以实际工程为例,阐述了超声波法连续墙成槽质量检测的过程,并提出了可改进的方向,本文的结论可为同类型的研究和工程应用提供参考。

The diaphragm wall is a kind of supporting structure in deep foundation pit and subway engineering. The quality of the groove is directly related to that of the diaphragm wall. In the process of construction of diaphragm wall,applying ultrasonic method to detect the width and verticality of the groove can effectively guarantee the quality. Taking the practical engineering as an example,this paper expounds the process of the ultrasonic method in the quality inspection of the diaphragm wall,and puts forward the possible improvement directions.The conclusion of this paper can provide some reference for the same type of research and engineering application.
