Automatic tunneling method of shield tunneling machine

Abstract

The invention discloses an automatic tunneling method of a shield tunneling machine, which comprises the following steps: S01, starting the shield tunneling machine, and manually setting parameter values of a soil bin pressure automatic dynamic balance module, a posture automatic deviation correction module, a muck automatic improvement module and a shield tail grease automatic injection module of the shield tunneling machine; s02, a one-key start-stop key is pressed down, a propelling system, a screw conveyor system, a foam system, a cutterhead system, a shield tail grease system, a gear oil system, a grease system and a water system are started, and tunneling is started; and S03, real-time data in the tunneling process of the shield tunneling machine are obtained through a soil bin pressure automatic dynamic balance module, an attitude automatic deviation correction module, a muck automatic improvement module and a shield tail grease automatic injection module, and automatic adjustment of the shield tunneling machine is achieved through mutual synergistic effect. The precision of attitude control and soil pressure control is improved, muck improvement is facilitated, cutterhead mud cake monitoring and processing are convenient, and the surrounding environment and engineering risks are reduced.

Description

technical field [0001] The invention relates to an automatic tunneling method of a shield machine. Background technique [0002] With the rapid development of subways, underground excavation construction has become more and more popular. The shield method has been used more and more in urban subway construction due to its advantages of fast excavation speed, small occupied pavement area, and fast pavement recovery. The key to the construction method is to ensure that the posture and position of the shield machine are correct, so as to ensure that the travel and design route of the shield machine are within the allowable range of deviation. [0003] At present, the similarity of domestic equipment is very common, and the precision of manual operation is very high. With the development of urban infrastructure, the surrounding environment of subway, underground space development and other projects is becoming more and more sensitive, and the geological conditions are complex an...
