PURPOSE:To enable the correction of an initial tilt within a definite range in every direction, by putting a fluid into a casing or frame body containing a tilt sensor, and by burying and fixing the tilt sensor vertically in an object to be measured. CONSTITUTION:An inclinometer is inserted into a guide pipe 18 formed aslant, by using a rod 19 fitted to a screw hole 15a of a rod fixing member 15. On the occasion of this insertion, guide rollers 16a and 16b fitted to a frame body 9 are fitted slidably in and guided by the guide grooves 18a and 18c of the guide pipe 18, and therefore the inclinometer is held in the direction taken at the time point of its insertion into the guide pipe 18 while it is lowered to a point at which a tilt is measured. Inside the frame body 9 of the inclinometer set at the point of measurement, a tilt sensor 8 is suspended vertically by a cable 10 irrespective of the tilt of the guide pipe 18 and is put in the state in which it outputs a signal corresponding to a tilt angle of 0 deg.. |
