トペースト注入用低圧力自動制御装置。 A low-pressure automatic control device used when back-filling mortar/cement paste is equipped with a control valve that communicates with the return port between the paste supply port and the injection port, a pressure sensor on the injection port side, and a control valve that communicates with the return port between the paste supply port and the injection port. Equipped with a control device that issues a valve-to-valve signal to the actuator of the control valve for a certain period of time set by a timer based on a signal from the pressure sensor, and a switching valve that holds the actuator in the valve open state when there is no signal from the pressure sensor. A low-pressure automatic control device for mortar/cement paste injection, which is characterized by:
