Description

technical field [0001] The invention relates to the technical field of automatic control of shield tunnels, in particular to a remote automatic control device for shield tunnels. Background technique [0002] At present, the control of shield tunneling in China mainly relies on manual operation. The control of shield tunneling is affected by personal factors such as the operator's ability, physical condition, and emotion, and the quality of control is difficult to guarantee. With the development of the shield method to large depth, large section, and long distance, coupled with the improvement of the construction environment and working conditions, the improvement of construction quality, the avoidance of construction hazards and the shortage of skilled workers, the development of automation technology has become necessary. [0003] The application number is CN201611182388.7, and the application date is 20161220. The invention discloses a compound shield machine cutter head ...
