方法に関する。This invention was arrived at as a result of various studies to prevent the above-mentioned accidents during underground excavation work. An electric circuit is normally closed at the inner tip of the excavation means, so that when a buried iron object is approached during excavation, magnets are attracted and the electric circuit is opened, allowing the excavation to be stopped or the excavation to be stopped. This invention relates to a method for detecting buried objects of gold maple, which consists of using a self-made magnetic switch.
以下図面によって本発明を具体的に説明する。The present invention will be specifically explained below with reference to the drawings.

が形成されるのである。In FIG. 1, a magnet 1 is floating on mercury 2 contained in a mercury reservoir 6, and the upper surface of the magnet 1 is in contact with an upper wall 4. The mercury reservoir 3 is made of a material that does not affect magnetism, such as aluminum, glass, ceramic, etc. If aluminum is used, the mercury 2 or mercury reservoir 6 and the upper wall 4 are insulated with a suitable insulating material 5. A magnetic switch is formed by pulling out a lead wire from a part of the upper wall 4 and the water reservoir 5 and connecting it to a power source and, for example, an alarm that will issue an alarm when the power is turned off.
