据报道,南京水利科学院王伍平等人应用声波CT检测钻孔灌注桩的内部质量,其结果细致、准确,不受桩长、桩径、缺陷数量的影响,并可提取混凝土强度资料等优点,因此它广泛用于桥梁、高层建筑等基础灌注桩的检测中。 利用声波层析成像技术可以解决一般超声法测桩(如对测法)不直观、精度不够、经验性成分居多等技术上的缺陷问题。它是将测区划分网格,在一侧面上某点放置发射换能器T,另一侧面上某点放置接收换能器R,两点连线即为其待测测线,此测线可垂直桩轴或与其斜交,如此设计网格,布置若干测线,将一系列所
According to reports, Nanjing Academy of Sciences, Wang Wuping and other people using acoustic CT to detect the internal quality of bored piles, the results of meticulous and accurate, without the impact of pile length, pile diameter, the number of defects, and can extract the advantages of concrete strength, Therefore, it is widely used in the testing of bored piles such as bridges and high-rise buildings. The use of acoustic tomography imaging technology can solve the general ultrasonic method of measuring piles (such as the test method) is not intuitive, accuracy is not enough, the majority of empirical components and other technical defects. It is divided into grid measuring area, placed on one side of a launch transducer T, on the other side of a point to receive the transducer R, two points for the line to be measured line, the line The vertical axis of the pile or oblique to it, so the design grid, the layout of a number of survey lines, a series of
