WIPO Patent Application WO/2023/167383
Kind Code:
A1
Abstract:
The multi-purpose total inspection device of the present invention is a multi-purpose total inspection device for preliminary inspection of a bored hole (A) bored for steel pipe multistage grouting tunnel reinforcement, and comprises: a cylindrical inspection rod (10) introduced into a bored hole (A), an upper finish cap (11) being installed at the upper end of the cylindrical inspection rod (10), the lower end thereof being waterproof, and the cylindrical inspection rod (10) having an inner space portion; an inclination sensor (20) installed inside the inspection rod (10) to measure the inclination angles of the upward, downward, leftward, and rightward inclination angles of the bored hole (A); a probe camera (30) installed at the lower end of the inspection rod (10) to photograph the inside of the bored hole (A); a groundwater detection sensor (40) installed at the lower end of the inspection rod (10) to identify groundwater leakage in the bored hole (A); a depth measurement device (50) for measuring the depth of the bored hole (A) through the length of movement of a depth measurement cable which is drawn concurrently with uplifting the inspection rod (10), to which the depth measurement cable is fixed while being wound at the entrance side of the bored hole (A); a controller (60) electrically connected to each of the inclination sensor (20), the probe camera (20), the groundwater detection sensor (40), and the depth measuring device (50) to receive each piece of measured information; and a monitor device (70) connected to the controller (60) so as to display each piece of information transmitted from the controller (60).
