Intelligent shield parameter abnormality prompt method and device

Abstract

The embodiment of the invention provides an intelligent shield parameter abnormality prompt method and device. The intelligent shield parameter abnormality prompt method comprises the following stepsof obtaining a target parameter measured value, wherein the target parameter measured value comprises at least one of a synchronous grouting quantity measured value, a soil pressure measured value, ashield attitude measured value, a torque measured value, a thrust measured value and an excavated soil volume measured value; and based on the comparison result of the target parameter measured valueand a preset corresponding threshold value, sending out corresponding prompt information. According to the intelligent shield parameter abnormality prompt method provided in the embodiment, six core parameters directly affecting construction safety are monitored in real time, the prompt information is intelligently sent immediately once the parameters are abnormal, shield construction is closely combined, the construction risk is lowered, and safety of shield construction is fully ensured.

Description

technical field [0001] The present invention relates to the technical field of tunnel construction, and more particularly, to an intelligent prompting method and device for abnormal shield parameters. Background technique [0002] The shield tunneling method has become the mainstream construction method in the current interval tunnel construction. Compared with the traditional open cut and mining method construction, the shield tunneling method has a high degree of mechanization, low labor participation rate and complete parameter records, and is highly informatized and digital. [0003] At present, shield tunneling construction management is extremely dependent on the control of shield tunneling parameters by shield tunneling operators, but the level of shield tunneling operators is uneven. Due to the ever-changing hydrogeological conditions underground, it is impossible to accurately judge whether the shield parameters are reasonable only by the shield operator, and it is ...

[0003] At present, shield tunneling construction management is extremely dependent on the control of shield tunneling parameters by shield tunneling operators, but the level of shield tunneling operators is uneven. Due to the ever-changing hydrogeological conditions underground, it is impossible to accurately judge whether the shield parameters are reasonable only by the shield operator, and it is also impossible to analyze and control the shield parameters 24 hours a day
