- Abstract:
- In order to solve the problems of high safety risk and many casualties in the dredging operation of large drainage culvert, a general safety control system for dredging of large-scale drainage culvert based on the architecture of perception layer, transmission layer, processing layer and application layer is constructed through the research on the release mechanism of toxic, flammable and explosive gases, the rule of blocking failure, the key points of personnel control and the requirements of emergency rescue. The system includes functional modules such as hierarchical ventilation, water level response, personnel control, coverage monitoring and auxiliary rescue. It was applied in the phase Ⅰ comprehensive management project of Huangxiao-Jichang River basin in August 2020, achieving the goal of zero casualties in dangerously dredging 29.4 km of large-scale drainage culvert, and effectively reducing the safety risk of dredging operation of large-scale drainage culvert.
