    • PROBLEM TO BE SOLVED: To integrate a reinforcing-bar distortion detection structure capable of detecting clod movement on a slope with high sensitivity into a cylindrical reinforcing-bar when performing reinforcing-bar insertion work using the cylindrical reinforcing-bar.SOLUTION: In a hollow sensor rod 5, a small diameter part 7 and a large diameter part 8 for forming a little gap to an inner surface of a cylindrical reinforcing-bar 1 are formed alternately. The hollow sensor rod 5 is inserted into the cylindrical reinforcing-bar 1 and both ends of the hollow sensor rod 5 are fixed to the cylindrical reinforcing-bar 1. A distortion gauge 13 is affixed on an outer circumferential surface of the small diameter part 7 of the sensor rod, and a lead wire of the distortion gauge 13 is put from a hole which is opened in the small diameter part, into the sensor rod and pulled out of an apex of the cylindrical reinforcing-bar 1. When the cylindrical reinforcing-bar is bent and deformed by movement of clod, the sensor rod is bent and deformed in accordance with the bending deformation of the cylindrical reinforcing-bar by action of the large diameter part 8 which forms a little gap to the inner surface of the cylindrical reinforcing-bar 1. In that case, the outer circumferential surface of the small diameter part is distorted larger than the outer circumferential surface of the large diameter part, such that the bending deformation of the cylindrical reinforcing-bar 1 can be detected with high sensitivity by the distortion gauge affixed to the outer circumference of the small diameter part.
    • 要解决的问题:在使用圆柱形加强筋进行加强筋插入加工时,将能够在高灵敏度的斜坡上检测泥土运动的钢筋变形检测结构集成到圆柱形加强杆中。解决方案:在中空 交替地形成传感器杆5,小直径部分7和用于与圆柱形加强杆1的内表面形成小间隙的大直径部分8。 将中空传感器杆5插入圆柱形加强杆1中,将中空传感器杆5的两端固定到圆柱形加强杆1上。在小直径部7的外周面上固定有变形量规13 的传感器杆,并且将变形量计13的引线从在小直径部分中打开的孔放入传感器杆中并从圆柱形加强杆1的顶点拉出。当圆柱形加强件 杆通过泥土移动而弯曲变形,传感器杆根据圆柱形加强筋的弯曲变形而弯曲变形,大直径部分8的作用是与圆柱体的内表面形成一点间隙 在这种情况下,小直径部的外周面比大直径部的外周面变大,使得圆筒状的弯曲变形 可以通过固定在小直径部分的外圆周上的变形计高灵敏度地检测钢筋1。
