摘要： PURPOSE: To predict more accurately and speedily the deformation and destruction of the ground by connecting joint parts of measurement pipes of unit length through rotary joints and slide joints to necessary length, and installing an angle sensor which detects an angle of rotation and an extension sensor which detects a slide quantity.
CONSTITUTION: A necessary number of measurement pipes 1 are connected mutually to necessary length by using a rotary joint 2 and a slide joint 3 at a node between a couple of pipes and used while buried perpendicularly in the boring hole at a place to be measured. If the ground slants or rotates to deform, the inclination between two adjacent measurement pipes 1 and 1 causes the angular displacement of the rotary joint 2 and appears as the relative angular displacement between a bracket 6 and a connecting part 8. This angular displacement is detected as the angle of rotation of the input shaft pulley 4a of the angle sensor 4. If the ground is displaced perpendicularly, it causes extension or contraction between two upper and lower adjacent measurement pipes 1 and 1 to displace the slide joint 3, which is detected a s the angle of rotation of the input shaft pulley 5a of the angle sensor 5.
