Problems solved by technology

Although the above-mentioned method of intelligently controlling tunneling control parameters similar to the intelligent algorithm has high prediction accuracy, it only considers the influence and adjustment of the front geology on the tunneling control parameters, and does not take into account the overall parameters of muck improvement and grouting.
However, in actual excavation, the parameters of muck improvement and grouting have a great influence on shield excavation, which may mislead the construction personnel to adjust the pressure of the soil bin. Therefore, the intelligent control of excavation control parameters recommended by the above method is not optimal. Driving control parameters

Abstract

The present invention provides a shield tunneling control system and method. The system includes: an earth bin pressure control value determination unit, which is used to calculate the earth bin pressure value of the target formation, and based on the earth bin pressure value, determine the current excavation value. Soil bunker pressure control value; online monitoring unit, used for real-time monitoring of the characteristic information value of the target stratum, the characteristic information value is that the shield operator performs tunneling operation according to the current tunneling control parameters under the condition of maintaining the soil bunker pressure control value The control unit is configured to obtain the adjustment value of the tunneling control parameter according to the characteristic information value; adjust the current tunneling control parameter according to the adjusted value of the tunneling control parameter until the characteristic information reaches a stable state. The invention can realize the control on the excavation of the shield tunneling machine, and has high control precision.

Description

technical field [0001] The invention relates to the technical field of shield machine construction automation and intelligence, in particular to a shield tunneling control system and method. Background technique [0002] The shield machine is a special engineering equipment for tunnel excavation, which can realize tunnel construction operations such as excavating rock and soil, belt slag removal, synchronous grouting, and segment assembly. At present, in most shield tunneling constructions, the pressure control value of the soil bin is calculated by a theoretical formula, and adjusted according to the later ground subsidence value, and the project management personnel issue instructions, which has a certain lag; due to the geological conditions in front of the shield tunnel Complex and changeable, the tunneling control parameters change quickly, and the main driver adjusts according to the changes of the tunneling control parameters relying on personal experience; but in fac...
