An oil system of a shield machine has a direction correction device which is used to make the shield machine travel on a predetermined path. An electric control device is used to remotely control the operation of the shield machine. An oil circuit device is electrically connected to the direction correction device and the electric control device, and the oil circuit device has a remote hydraulic power source to provide power to the shield machine. An oil pressure control module is disposed in the oil circuit device, and is coupled to the remote oil pressure power source, a hydraulic motor and a direction correction module through a pipeline. Wherein, the remote oil pressure power source provides an oil pressure to the oil pressure control module, and the oil pressure control module provides the oil pressure to the hydraulic motor or the direction correction module to make one drill bit of the shield machine rotates forward or backward, or the shield machine is adjusted and corrected to a predetermined path to drill a hole. |
