Abstract

The invention discloses an intelligent tunneling control method, system and equipment for a composite stratum shield tunneling machine and a medium. The method comprises the following steps: acquiring the plastic flow state of the tapping muck of the shield tunneling machine; adjusting a modifier set value of the muck improvement system according to the plastic flow state; the excavation bin soil pressure of the shield tunneling machine is obtained; adjusting the rotating speed of a spiral conveyor according to the soil pressure of the excavation bin, and conveying the muck by using the spiral conveyor; whether the cutterhead torque reaches the maximum torque or not is judged, and if the cutterhead torque reaches the maximum torque, the tunneling speed of the shield tunneling machine is reduced; and judging whether the thrust of the cutterhead reaches a preset maximum thrust value or not, and if the thrust of the cutterhead reaches the preset maximum thrust value, reducing the tunneling speed of the shield tunneling machine. According to the scheme, the plastic flowing state of the discharged muck can be obtained, the modifier set value of the muck improvement system is automatically adjusted, and the rotating speed of the spiral conveyor is automatically adjusted according to the soil pressure of the excavation bin. And construction parameters can be automatically adjusted in time, and manpower is saved.

Description

technical field [0001] The present application relates to the technical field of shield tunneling engineering, in particular to an intelligent tunneling control method, system, equipment and medium for a composite stratum shield tunneling machine. Background technique [0002] Shield machine is a kind of special engineering machinery for tunnel excavation. Modern shield machine integrates optical, mechanical, electrical, hydraulic, sensing, and information technology. Guiding and deviation correction functions have been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. [0003] In the excavation stage of the shield machine, in addition to the excavation speed of the shield machine, more attention should be paid to the safety of excavation. A series of dynamic change information caused by construction is fed back to the shield construction site in time, so that the site can adjust the construction parameters in time, optimize and impro...
