Problems solved by technology

[0003] However, due to the complex structure of the shield machine itself, harsh working environment, human decision-making mistakes, insufficient risk estimation, improper operation, coupled with the long construction period, large scale and complex geology of tunnels and underground projects, etc. The probability of risk occurrence is relatively high, which brings many difficulties and challenges to the risk prevention and control of shield machine construction
Once an accident occurs to the shield machine, it will affect the progress of the project in the slightest, and cause casualties, economic losses and bad social impact in severe cases.
[0004] The traditional shield machine construction risk management and control method mainly relies on the manual identification and early warning of project technicians, which is difficult to achieve timeliness and accuracy, and the risk factors cannot be grasped by the decision-making layer of the enterprise, which affects the decision-making of the enterprise, which is completely impossible. Adapting to the Needs of the Development of Shield Machining Method

Abstract

The invention discloses a construction risk prevention and control method and a construction risk prevention and control system for a shield tunneling machine. The method comprises data acquisition and transmission, big date storage, processing and analyzing, risk recognition and early warning. The data mainly comprises machine data, fault data, guide data, ground settling data, duct piece gesturedata and engineering data. The big data storage and analysis and processing comprise a server and big data technology related software. The risk recognition and early warning comprise steps of engineering construction risk prevention and control, machine fault risk early warning, heading parameter early warning, quality risk prevention and control, construction period risk prevention and controland the like. The construction risk prevention and control method and the construction risk prevention and control system for the shield tunneling machine based on big data analysis can establish an informationized risk prevention and control system and avoid or reduce loss to a project due to risks such as equipment faults, staff operation errors and the like effectively, so that safe and efficient construction of the shield tunneling machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shield tunneling construction, in particular to a method and system for preventing and controlling the construction risk of a shield tunneling machine. Background technique [0002] As the main equipment for underground space construction, the number of shield machines continues to increase and the application fields and geographical breadth are getting larger and larger. According to statistics, as of now, there are nearly 1,800 domestic shield machines of various types. [0003] However, due to the complex structure of the shield machine itself, harsh working environment, human decision-making mistakes, insufficient risk estimation, improper operation, coupled with the long construction period, large scale and complex geology of tunnels and underground projects, etc. The probability of risk occurrence is relatively high, which brings many difficulties and challenges to the risk prevention and control of...
