PURPOSE: A multipurpose depth measuring device is provided to allow a user to conveniently and accurately confirm and measures the depth of an underground facility regardless of environments such as the environment in which the underground facility is filled with water or in which the underground facility is dry. CONSTITUTION: A multipurpose depth measuring device (10) includes a body unit (11), an electrode unit (13), a circuit unit (12), and a weigh (15). The body unit forming a main body includes an electrode accommodation unit (111), a diaphragm (113), and a weight accommodation unit (115). The electrode unit is accommodated in the body unit, and the circuit unit generates a signal when a current is applied to the electrode unit. The weigh is mounted on the end of the body unit, and the current is applied to the electrode unit when the weight is in contact with the bottom of a facility. The weight includes a weighting unit (151), an elastic support unit (153), and a stopper unit (155). |
