Urban tunnel maintenance engineering refers to the regular inspection, maintenance and management of tunnels in the city. The aim is to ensure that the tunnel is structurally safe, functional, and environmentally clean, thus ensuring the safety and smoothness of urban traffic. Urban tunnel maintenance engineering is a comprehensive work, which requires the support of multi-faceted professional knowledge and skills. Structural Inspection & Maintenance:Regular inspection and maintenance of the tunnel structure, including the walls, ceilings, floors, and drainage systems. Through regular inspection and maintenance, structural damage or potential safety hazards can be found in time, and corresponding maintenance measures can be taken to ensure the stability and safety of the tunnel structure.
Tunnel Facility Maintenance:Regular inspection, maintenance and management of various facilities of the tunnel, including lighting, ventilation, fire protection, monitoring and other facilities. These facilities are essential for the proper functioning and maintenance of the tunnel, and must be guaranteed to function properly and, if necessary, repaired or replaced.
Traffic Safety Management:Ensure traffic safety in the tunnel, including the supervision of vehicle traffic, the installation and maintenance of traffic signs, and the management of emergency lanes. Clear traffic signs and traffic lights are set up in the tunnel, and the supervision of vehicle driving is strengthened to ensure traffic order and safety in the tunnel. 
Environmental Health Management:Maintain a clean and hygienic environment in the tunnel, including cleaning the walls and floors in the tunnel, dealing with stagnant water in the tunnel, removing garbage, etc. Good sanitation guarantees the comfort and safety of the tunnel and prevents the growth of bacteria and the spread of diseases. Disaster prevention and control: miningTake measures to prevent and deal with disasters in the tunnel, including natural disasters such as fires, floods, **, and man-made disasters such as traffic accidents. In the event of a disaster, emergency measures should be taken in a timely manner to ensure the safety of personnel and minimize property losses and environmental damage.
Regulatory Development & Enforcement:According to the relevant national and local regulations and standards, formulate tunnel maintenance norms and rules and regulations suitable for the region, and supervise the implementation. Through the formulation and implementation of norms and rules and regulations, the standardization and standardization of tunnel maintenance work can be ensured, and work efficiency and quality can be improved.
Information Management:Establish a tunnel maintenance information system to record, analyze and store information such as tunnel inspection, maintenance and management. Through the establishment and maintenance of the information system, the real-time monitoring and management of tunnel maintenance work can be realized, and the decision-making efficiency and accuracy can be improved.
Training & Exercises:Carry out professional training and drills for tunnel maintenance personnel to improve their professional skills and work ability. Through training and drills, tunnel maintenance personnel can enhance their ability to respond to emergencies and collaborate, and improve work efficiency and quality.
Tunnel civil works cost:This includes the cost of tunnel excavation, supporting, lining, pavement laying, etc. These are the basic works of tunnel construction, and their costs usually account for a large part of the cost of the entire tunnel maintenance project. Tunnel mechanical and electrical equipment installation project cost:This includes the cost of installing equipment such as lighting, ventilation, fire protection, surveillance, etc. These pieces of equipment are essential for the proper operation and maintenance of the tunnel, so their costs need to be fully considered.
Cost of safety measures for tunnel construction:This includes the cost of safety nets, safety signs, ventilation equipment, etc. These fees are to ensure safety during construction, and to protect the lives and health of workers.
Other Costs of Tunneling Works:This includes management fees, survey and design fees, project supervision fees, etc. These fees are to ensure the smooth implementation and management of the project, as well as to pay the design and supervision companies for professional services.
Preparation fee:The reserve fee includes the basic reserve fee and the spread reserve fee. The basic reserve fee is to deal with possible unexpected situations and unknown factors, while the spread reserve fee is to cope with possible future fluctuations in labor costs, material costs, machinery usage costs, etc.
