PURPOSE: A measuring device and a method for obtaining information with respect to the roughness of an excavated hole is provided to obtain the roughness of an inner surface of the excavated hole accurately, thereby measuring an inclination of an inner wall of the excavated hole. CONSTITUTION: A measuring device for obtaining information with respect to the roughness of an excavated hole comprises a measuring sensor(10), a housing member, and a membrane member(30). The measuring sensor receives information with respect to the roughness of an inner wall surface(110) of an excavated hole(100) for pile construction. The housing member includes an upper plate(21) and a lower plate(22) which are mutually spaced in a vertical direction. The housing member includes a sensor installing rod(23) is installed in between the upper and lower plates, and the measuring sensor is mounted. The membrane member is formed of an elastic film firmly surrounding a gap between the upper and lower plates. |
