Background
The difficulty faced in the double prevention work of safety risk is implemented at present bridge tunnel engineering job site:
(1) the informing content of the construction safety risk is complex, and the text chart is difficult to be adopted to carry out full factor expression
The core result of risk classification management and control is safety risk notification, risk factors of engineering construction safety risks comprise four aspects of personnel, machinery, environment and management, particularly, construction environments comprise engineering structures, surrounding surface terrains, underground rock stratums, pipelines and the like which are complex three-dimensional objective entities, safety risk notification contents of all construction operation activities comprise risk factors, risk events, risk control measures and the like, and the safety risk notification contents are difficult to comprehensively describe by adopting texts, pictures and other modes.
(2) The hidden trouble investigation working points are multi-sided and wide, the content is complex and the dynamic change is difficult to be managed by the ledger
The core result of hidden danger investigation and treatment is that the risk control measures of each operation activity are implemented in place, otherwise, the potential safety hazard is formed, and closed-loop rectification and improvement are carried out. The bridge and tunnel engineering points are long in multiple lines, construction operation work points are distributed and dispersed, construction operation activities are various, risk factors and control measures corresponding to the construction operation activities are different, potential safety hazard investigation work points of a construction site are many-sided and wide, and inspection contents are different; and the construction site is changed along with the construction progress, the static safety risk investigation plan is difficult to accord with the actual situation of the site, and the ledger management mode is difficult to deal with the safety hidden danger investigation work of discrete distribution, complex content and dynamic change.
