POSITION SUSTAINABLE UNDERGROUND PIPE LOCATING DEVICES

摘要

The present invention relates to a device for checking a location of an underground pipe capable of maintaining a position. More specifically, the device for checking a location of an underground pipe capable of maintaining a position comprises: a fixed housing cover to open and close an installation space of a fixed housing body installed on the surface of the ground above an underground pipe; an upper end checking unit to check a location of an upper end of the underground pipe; a first side end checking unit to check a location of a lower end of one side of the underground pipe; a second side end checking unit to check a location of a lower end of the other side of the underground pipe; a moving housing to install the upper end checking unit, the first side end checking unit, and the second side end checking unit on the fixed housing body to be displaced; a measurement control unit to receive measurement values of the upper end checking unit, the first side end checking unit, and the second side end checking unit to check the location of the underground pipe; air pockets to enclose the fixed housing body; a displacement sensor to measure displacement of the fixed housing body; and a maintaining control unit to receive a signal of the displacement sensor to adjust a pressure of a corresponding air pocket by a displaced distance to maintain the fixed housing body in an initial installation position. According to the present invention, the location of the underground pipe buried underground can be easily checked. The position of the fixed housing body can be maintained to quickly handle. Conventional loss caused by negligence can be reduced and prevented to improve work efficiency.
