How to ensure construction safety during shaft boring machine (TBM) construction? Ensuring construction safety during TBM construction requires a series of comprehensive measures. These measures can be divided into technical measures, organizational measures, and management measures:
I. Technical Measures
1. Equipment Selection and Maintenance: Select suitable TBM equipment, ensuring its technical performance and quality meet construction requirements. Regularly inspect and maintain the equipment to ensure it is in good working condition.
2. Construction Scheme Design: Develop a detailed construction plan, including construction procedures and emergency response plans, ensuring the plan's scientific validity and feasibility.
3. Geological Exploration: Conduct a detailed geological exploration before construction to understand the underground structure, soil type, and hydrological conditions, avoiding encountering adverse geological conditions.
4. Monitoring System: Install a monitoring system to monitor surface settlement, tunnel deformation, and gas concentration in real time during construction, promptly detecting and handling any abnormalities.
5. Ventilation and Drainage: Ensure good ventilation at the construction site to prevent the accumulation of harmful gases. Simultaneously, ensure proper drainage to prevent water accumulation from affecting construction safety.
II. Organizational Measures
1. Personnel Training: Provide safety training to construction personnel to ensure they understand equipment operation procedures and construction safety requirements. Special emphasis should be placed on emergency response capabilities.
2. Safety Responsibility System: Clearly define the safety responsibilities of personnel at all levels, establish a comprehensive safety management system, and ensure that each link has a designated person responsible.
3. On-site Management: Strengthen on-site management, conduct regular safety inspections, and promptly rectify any hidden dangers. Ensure orderly on-site operations and that all safety measures are implemented effectively.
III. Management Measures
1. Safety Regulations and Systems: Formulate and strictly enforce all safety regulations and systems to ensure that construction is conducted according to established procedures.
2. Emergency Plans: Develop detailed emergency plans, including response measures for sudden accidents and evacuation plans, and conduct regular drills to improve emergency response capabilities.
3. Safety Investment: Ensure sufficient safety investment, including safety equipment, monitoring systems, and emergency supplies, to ensure that safety measures are in place.
4. Regular Inspections and Assessments: Regularly inspect and assess construction safety, summarize lessons learned, and continuously improve safety management.
By comprehensively applying the above-mentioned technical, organizational, and management measures, the safety of shaft boring machine operations can be effectively ensured, and the risk of accidents can be reduced.
