1. The general manager of the company shall conduct a key inspection on the tunnel construction at least once a month, and conduct a comprehensive inspection on the tunnel construction every quarter, and fill in the Tunnel Construction Safety Inspection Record Book in time for inspection and handling.
2. In charge of the leadership at least twice a month to focus on the inspection of heavy (difficult) point tunnel construction, at least once a month to conduct a comprehensive inspection of the general tunnel construction, and fill in the tunnel construction safety inspection record book in time, so as to check and handle.
3. The competent department and technical personnel in charge should establish a safety management account for tunnel engineering, and the department heads and technical personnel in charge should focus on the heavy (difficult) tunnel construction at least twice a month, and conduct a comprehensive inspection for the general tunnel construction at least once a month, and fill in the Tunnel Construction Safety Inspection Record Book in time for inspection and handling.
Eighth tunnel safety inspection focus and treatment measures
1. Key points of tunnel safety inspection: implementation of design excavation scheme, smooth blasting control, advanced geological prediction and monitoring measurement, follow-up progress and construction quality of initial support (secondary lining and inverted arch construction), whether geological conditions meet the design, gas monitoring and ventilation of gas tunnel, construction power consumption, initiating explosive device management, emergency plan and drill, and duty performance of safety personnel, etc.
2. Fill in the rectification notice on the spot for the problems detected, check the records to be true, put forward the requirements for handling and rectification, and designate a special person to be responsible for tracking and implementing the rectification.
Ninth the establishment of tunnel safety meeting, analysis and reporting system.
1. The company organizes the construction, design and supervision units to hold regular tunnel safety analysis meetings every quarter to sort out and solve the problems existing in tunnel construction safety, establish a tunnel construction safety analysis record book and make records.
2. The leaders in charge of the company and the security department collect, check and file the inspection records every month, sort out and analyze the problems existing in the safety of tunnel engineering and the rectification situation, and record them in the Tunnel Construction Safety Analysis Record Book.
3. According to the requirements of the company's leaders, the Security Department will regularly report to the company's leaders the existing problems in tunnel engineering safety, handling the rectification situation and the next safety measures.
Article 10 Regular notification system
The company reports the safety situation of tunnel engineering in the pipeline every month and issues the main points of tunnel engineering safety work.
Eleventh responsibility assessment system
1. The company evaluates the tunnel safety control of the construction, design and supervision units through credit evaluation and related systems, and punishes the responsible units and individuals who have problems.
2. The company conducts internal evaluation according to the implementation of tunnel safety management responsibilities, and rewards and punishments according to the corresponding evaluation methods.
Chapter III Formulation, Review and Implementation of Major Programmes
Article 12 For heavy (difficult) tunnels with shallow buried unsymmetrical pressure, bad geology and long steep slopes, the company organizes construction, design and supervision units to hold special meetings to study safety control measures and review construction plans; Invite experts to study and improve construction safety control measures when necessary.
Article 13 The construction unit shall submit the special construction scheme of the above-mentioned tunnel to the factory director for examination and approval after being examined and signed by the competent leader of the enterprise, and then report it to the company for filing before implementation.
Fourteenth supervision units shall strengthen the on-site monitoring of the implementation of the above-mentioned tunnel construction organization plan, and strictly supervise the construction units to organize the construction according to the approved plan. During the implementation of concealed works, digital image data should be kept for future reference.
Chapter IV Strengthening Geological Advance Forecast and Monitoring
Fifteenth advanced geological prediction is an effective means to prevent all kinds of sudden geological disasters, and the construction unit must incorporate advanced geological prediction into the process management.
1. The construction unit shall be equipped with advanced geological prediction equipment according to the bidding commitment and the needs of tunnel construction, and make an implementation plan for advanced geological prediction.
2. The professional geologist of the construction unit shall describe and record the surrounding rock of the tunnel face in detail, and draw a geological sketch of the tunnel face, and the geological engineer shall accurately judge the surrounding rock.
3. For poor geological areas such as loose strata, shallow buried areas, fault fracture zones, water-rich areas and areas where rockburst may occur, it is required to use one or more comprehensive methods of geological prediction system, geological radar and infrared detector to make comprehensive geological prediction, and at the same time, adopt advanced horizontal drilling methods to accurately predict the engineering geological and hydrogeological conditions of surrounding rocks.
4. Geological description and advanced prediction results are managed by data collection method combining daily inspection lot acceptance with special report. Geological engineers collect geological sketches every day, analyze and summarize them, and report to the technical director; Weekly summary, submitted to the supervision unit for approval; Provide data and maps to design units and companies every two weeks, and provide segmented results reports.
5. Significant changes in geological conditions and design may cause geological disasters or affect the safety of tunnel construction (faults, joint-intensive zones, water-rich zones, contact zones with different lithology, etc.). ), and deliver the special prediction results to the design unit for dynamic design in time. In case of emergency, preventive measures should be taken in time and reported to the company to ensure construction safety.
6. The company should strengthen supervision and inspection, focusing on the equipment and personnel for advanced geological prediction, the implementation and quality of the prediction scheme, and the safety control of the tunnel construction site. , and will check the results into the credit evaluation.
