钢管混凝土超声波检测的应用

Ground Penetrating Radar(GPR) in the Application of the Surfacing Layer

为了解钢管内混凝土的泵注密实性及混凝土与钢管内壁的胶结质量,采用非金属超声波检测仪测量超声波在钢管混凝土中传播时的声速、声时以及频率变化,对该桥4榀拱肋钢管混凝土的施工质量进行非破损检测。

To understand of the steel pipe concrete pump note the compactness and cementing quality of concrete and steel tube wall,adopts nonmetal ultrasonic detector to measure the velocity of ultrasonic propagation in concrete filled steel tube, the sound and the change of frequency, the construction quality of the four common concrete filled steel tube arch rib of the bridge on the damage detection.
