液の流れによって動揺しやすい欠点がある。However, the above conventional position detecting device has the following problems and features. A: The measuring stand 10 is a relatively simple wire inclination measuring method.
Even if there is a tilt error during installation, the wire tilt angle is not affected. However, there is a drawback that the inclination of the wire 17 is difficult to be accurately propagated to the inclinometer. This tendency is remarkable especially when the change in the wire inclination angle is small. In the embodiment, it is difficult to accurately detect the tilt angle corresponding to the positional deviation at a large depth of 100 m or more.
The wire tilt angle is about 1 when there is a 5 cm hole bend.
Minutes. B: If the attachment point O of the wire 17, which should be a fixed point, to the measurement pedestal 10 moves due to deformation of the measurement pedestal 10 or the like, this movement amount is proportionally multiplied to affect the position detection error. With the movement of the excavation position (always in underground wall construction),
Although the measurement gantry 1 also moves, the tilt error in the installation of the measurement gantry 10 at this time is also proportionally multiplied to affect the position detection error, as in the above case. C: There is a drawback that the weight and sensor 14c1 hanging in the stabilizing solution is easily shaken by the flow of the stabilizing solution.

している。In the present invention, whether or not the inclination of the rod 15 shows an accurate inclination as the underground wall excavator E moves greatly affects the accuracy of position detection. That is, the gist of the present invention is that the combination of the inclinometer 14 and the rod 15 makes it possible to detect minute hole bending of the deep-depth underground continuous wall excavator E. Therefore, this point will be described with reference to an embodiment. The calculated values (measured values) and the measured results were as follows. Consider a case in which the path of the underground continuous wall excavator E is displaced from the vertical line P by δ = 5 cm in the horizontal direction at the depths of 150 M, 100 M, and 50 M (see “FIG. 5”). The calculated value at a depth of 150M is as follows. Wire tension T = 100 Kg Radius of rotation of locking member 13 r = 1 cm Dynamic resistance coefficient k1 = 0.003 Initial dynamic resistance coefficient k2 = 0.006 Rod length L = 200 cm Horizontal wire force t = T * δ / D = 100
000g * 5cm / 15000cm≈30g Rod rotation moment M = L * t = 200cm *
30 g = 6000 g · cm Rotational resistance moment of locking member 13 Mt = T * k1 * r = 10000
0g * 0.003 * 1.0cm = 300g · cm Initial resistance moment Mt ′ = T * k2 * r = 10
Since 0000 g * 0.006 * 1.0 cm = 600 g · cm M> Mt ′, the calculated value δs of the horizontal displacement is δs = δ * (M-Mt) / M = 5 cm * (6000-300) / 600 = 4.75 cm. The calculated values at a depth of 100M are as follows. Calculation is omitted. δs = 4.85 cm The calculated value at a depth of 50 M is as follows. Calculation is omitted. δs = 4.92 cm On the other hand, the measured values were as follows. When the depth was 150 M, it was 4.9 cm, when the depth was 100 M, when it was 4.8 cm, when it was 50 M, it was 4.8 cm, which was in good agreement with the calculated value. Incidentally, the numerical values used in this calculation are those actually measured by the device used by the inventors in the experiments. In the above calculation formula, the horizontal component force of the wire is the depth D of the underground wall excavator E, and the rotation moment is the rod length L.
However, it is understood that the calculated value when the rod length is changed for each depth is shown in "Fig. 6". In FIG. 6, the calculation value of 0 does not satisfy M> Mt '. Also, the shorter the rod 15 in FIG.
Although the accuracy is reduced or it is inoperative, this is the state of the conventional method, that is, "the situation without the rod 15 of the present invention".
Is approaching. Note that the effects of wire slack and rod weight have been ignored in the above example because it has been confirmed separately that they are negligibly small.
