PURPOSE: A grouting device is provided to flexibly correspond to various environmental changes by correcting an injection rate, an injection speed, and an injection pressure while monitoring condition in real time. CONSTITUTION: A grouting device (100) comprises a supply device, a transfer pipe (110), a rod (120), a plurality of sensors, and a control unit. The sensor is installed in the transfer pipe or the rod and comprises a supply unit sensor (310) and a rod sensor (320). The control unit calculates the degradation of pressure from the rod sensor to a discharge unit through the degradation of the pressure due to height difference of the supply unit sensor and the rod sensor. The sensor is selected among a manometer, a flow meter, and a current meter. |
