In the process of tunnel construction, there are many sources of danger, which will not only threaten the life safety of construction personnel, but also adversely affect the progress and cost of the project. Therefore, understanding the main sources of danger in the construction process of tunnel engineering and taking corresponding measures to manage and control them is the key to ensuring the safety and smooth progress of construction.
1. The main source of danger in tunnel construction.
1.Collapse: In tunnel construction, due to complex geological conditions, such as soft surrounding rock, geological changes, etc., it may lead to the occurrence of collapse accidents.
2.Water inflow: During tunnel construction, if there is abundant groundwater, it may cause water inrush accidents and pose a threat to construction safety.
3.During tunnel construction, accidents may occur due to blasting operations or improper handling.
4.Mechanical injury: In tunnel construction, various mechanical equipment needs to be used, such as excavators, loaders, etc., if improper operation or maintenance, it may cause mechanical injury accidents.
5.Falls from heights: In tunnel construction, falls from heights may occur when construction crews are working at a higher position.
6.Object strike: In tunnel construction, various construction materials and tools need to be used, and if these items are not properly placed or used incorrectly, it may cause object strike accidents.
2. Hazard control measures.
1.Strengthen geological survey and design: Before tunnel construction, the geological survey of the construction area should be strengthened to understand the geological conditions and groundwater conditions, so as to provide an accurate basis for the design. At the same time, the design unit should reasonably design the tunnel construction plan and support plan according to the geological survey results to ensure construction safety.
2.Strengthen construction site management: The construction unit should strengthen the management of the construction site, establish and improve various safety management systems and operating procedures, and clarify the division of safety responsibilities and emergency plans. At the same time, safety inspections and assessments should be carried out regularly to discover and deal with potential safety hazards in a timely manner.
3.Strengthen personnel training and education: The construction unit should strengthen the training and education of construction personnel to improve their safety awareness and skill level. Especially for special operation personnel, special training should be carried out and the corresponding qualification certificate should be obtained before they can work.
4.Strengthen the formulation and drill of emergency plans: The construction unit should formulate detailed emergency plans, including emergency organization, communication and liaison, on-site disposal, etc. At the same time, emergency drills should be organized regularly to improve the emergency response ability of construction personnel.
5.Strengthen coordination and cooperation with other units and departments: In tunnel construction, coordination and cooperation with other units and departments are required. Therefore, the construction unit should establish a good cooperative relationship with the owner, the design unit, the supervision unit, etc., and jointly promote the construction progress and quality and safety management.
3. Summary. There are a variety of hazards in the construction process of tunnel engineering, which adversely affect the life safety of construction personnel and the progress of the project. Therefore, the construction unit should strengthen the management and control of hazards, and take corresponding measures to manage and control. At the same time, coordination and cooperation with other units and departments should be strengthened to jointly promote the smooth progress of tunnel construction.
