Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a geological displacement detecting device for detecting a geological displacement such as a ground or structural displacement, and a geological displacement monitoring for monitoring a landslide or a crack in a structure using the device. About the system.

[0002]

2. Description of the Related Art There is an urgent need to develop a system capable of predicting in advance the occurrence of disasters such as landslides caused by loosening of the ground due to heavy rain and collapse due to structural deterioration.

Conventionally, as a means for detecting, for example, loosening of the ground, there is a method in which a wire is stretched on the ground, and detection is made based on the fact that the wire has been cut due to fluctuations in the ground. However, this method requires a lot of work and time because wires must be stretched over a wide area, and it is difficult to specify the location and direction of displacement of the ground, and predict the degree of displacement. There is a problem that can not be.

In recent years, ground detectors using various measuring meters have been developed. For example, ground detectors have been developed using servo inclinometers or pipe strain meters in which a weight is horizontally supported on a case via a spring. There is a method for estimating the displacement of the landslide, the depth of the landslide surface and the amount of slip.

In the ground detector using the servo inclinometer, a pipe is buried in a boring hole provided in the ground, and a servo inclinometer is inserted into the pipe in a multistage so as to be wound up. The tilt angle is automatically measured continuously by the displacement of the spring while winding up. By measuring the lateral displacement, the displacement of the ground or the continuous ground wall, that is, the landslide can be measured.

Further, a ground detector using a pipe strain gauge is such that a number of vinyl chloride pipes having strain gauges affixed to appropriate portions in boring holes provided in the ground are sequentially inserted vertically while adding an intermediate pipe. The surrounding area is filled with sand and fixed.By measuring the bending strain by sequentially switching each vinyl chloride pipe as a detector at each depth, the magnitude and depth of slip can be estimated from the amount. It is.

[0007]

However, in the ground detector using these servo inclinometers and pipe strain meters, it is possible to measure the lateral displacement and bending strain of the ground, Since the position of the ground detector itself cannot be detected, it cannot be detected when the entire ground is displaced.

Accordingly, the present inventors use a gyro-type detector that detects an impact acceleration from the magnitude and direction of the external force due to the displacement of the ground and the inclination of the detecting section itself, and uses the gyro-type detector to detect the ground based on the detected data. The applicant has previously filed an application for inventing a geological displacement detecting device capable of accurately detecting even when there is a displacement as a whole.

However, even if this gyro-type detector is used, if an error occurs in the detection of the absolute angle or the acceleration, the error is accumulated with the passage of time, and despite the fact that the ground is not originally displaced, A detection signal is sent as if the ground is displaced, and there is a problem in the detection accuracy of the ground displacement.

On the other hand, 9 is a lid for closing the upper opening of the cylindrical body 1, and a solar cell 10 is mounted on the upper surface of the lid 9 as a power source for charging the battery 5. Also, the lid 9
Is provided with a transmission antenna 11 for transmitting the detection signal processed by the calculation unit 6 from the transmission unit 7 to a base station (not shown) as radio waves.

As shown in FIG. 2, the gyro sensor 2 has a piezoelectric element 2b for detecting an external force in three axial directions attached to each side surface of the triangular prism 2a, and when an acceleration α is applied to each piezoelectric element 2b, the acceleration becomes smaller. A voltage of a magnitude corresponding to the voltage is generated, and this voltage is input to the arithmetic unit 6.

FIG. 3 shows an example of a detection circuit applied to the gyro sensor 2. The three piezoelectric elements 2b are composed of two detection piezoelectric elements (L and R) and one feedback piezoelectric element (F
