Abstract
Disclosed is a full-length vibration excitable component device for measuring the strength of a rock and a cementitious material. The device comprises a steel rod member (1), a vehicle body (2), a vibration motor (3), a frequency measurement element (4), and an integrated lead harness (5); wherein, the steel rod member (1) has a through slot (6) in its interior, the vehicle body (2) is placed in the through slot (6), and the top of the vehicle body (2) is provided with a first mounting slot and a second mounting slot. In the device, a steel rod members (1) such as a reinforcing steel bar and an anchor rod widely used in geotechnical engineering and structural engineering is utilized as “signal generator”, the interior of the steel rod member (1) is grooved for installing a movable vibration excitation apparatus and a frequency measurement element arranged therein, and the positions of the vibration excitation apparatus and the frequency measurement element are accurately determined by using an integrated lead harness (5) with scales, thereby realizing operations of performing excitation and signal collection at any position along the full length of the metal rod member. Moreover, t…
