Abstract: Provided is an apparatus to measure the roughness of the inner surface of an excavation hole, including an upper support plate (20a) provided with a check valve (26) to allow the flow of an outward direction; a lower support plate (20b) disposed to be spaced apart from the upper support plate (20a); a measuring sensor (10); and a sensor installing rod (23) mounted with the measuring sensor (10), both ends being connected to the upper support plate (20a) and the lower support plate (20b). In a state whereby the apparatus is positioned at the measured depth in an excavation hole (100), each side of the upper support plate (20a) and the lower support plate (20b) is expanded by an injection of air into the inner space to come into a watertight contact with the inner surface (110) of the excavation hole (100). The air is introduced into the space between the upper support plate (20a) and the lower support plate (20b), such that the water filled in the space between the upper support plate (20a) and the lower support plate (20b) is discharged outwardly through the check valve (26). In a state whereby the inner surface (110) of the excavation hole (110) is exposed between the upper support plate (20a) and the lower support plate (20b), the measuring sensor (10) obtains the information about the roughness of the inner surface (110) of the excavation hole (100). The method to obtain the roughness information for the inner surface of the excavation hole includes obtaining the information about the roughness of the inner surface (110) of the excavation hole (100) by the usage of the apparatus.
