Smooth traffic conditions are the premise of urban development. In order to alleviate the pressure of urban traffic, a large number of municipal roads have been planned and built in China, which makes the construction safety of municipal roads concerned. Safety is the foundation of all engineering construction, and the construction of natural municipal roads is no exception. The common forms of municipal road construction are fully enclosed construction and semi-enclosed construction. Fully enclosed construction belongs to shutdown construction, and the potential safety hazards mainly come from the construction workers themselves, mechanical equipment and temporary electricity consumption. All kinds of machinery and equipment need to be used in the construction process, such as the lack of safety awareness and improper operation of construction personnel and the lack of effective safety management, which can easily lead to safety accidents and even machine failure and death. In semi-closed construction, the intrusion of social crowds and vehicles will increase uncertainty and inevitably increase the difficulty of construction. In order to reduce the accident rate of municipal road construction, safety management in construction must be done well. The following are the main contents and measures of municipal road construction safety management brought by Zhong Da Consulting for reference.

First, the importance of municipal road construction safety management

China's production safety policy is "safety first, prevention first, comprehensive management". Safety in production is the foundation of social stability and national economic development, and the premise of ensuring the realization of social benefits. Safety accidents in municipal road construction will not only affect the construction progress, but also cause huge economic losses to the construction enterprises themselves and even lead to negative public opinion. Municipal road construction has certain particularity, and there are many uncertain factors in the construction. In the event of a safety accident, it is easy to cause casualties and mechanical equipment damage. According to the statistics of relevant departments, in the first quarter of 20 15, there were 52 safety accidents in municipal road construction, and 68 people died. Compared with last year, the accident rate and death rate have obviously decreased, but the safety problem is still outstanding. At present, many municipal road projects still lack safety management, with many hidden dangers, great risks and frequent accidents. Municipal road construction is related to urban development and national economic construction. In order to ensure the personal safety and construction quality of construction workers and the surrounding people, it is necessary to effectively manage the construction site, scientifically predict safety risks, put an end to unsafe behaviors of construction workers, take effective measures to eliminate or reduce various safety hazards in construction, reduce the accident rate, ensure the smooth progress of construction, and ensure the social and economic benefits of municipal road projects.

Second, the security risks in the construction of municipal roads

According to statistics, in the first quarter of 20 15, 52 accidents occurred in a city, in which object strikes and machine injuries accounted for a large proportion, followed by lifting injuries and other injuries. Municipal road construction includes fully enclosed construction and semi-enclosed construction. Most of the hidden dangers of fully enclosed construction come from mechanical equipment, temporary electricity consumption and lack of safety management. Judging from the characteristics of municipal road construction, there is a lot of heavy physical labor. Under this construction condition, construction workers are prone to physical fatigue, which leads to distraction and safety accidents. In addition, many working procedures in municipal road construction involve cross-operation, and improper command in cross-operation may cause mutual injury, which is also one of the main reasons for throwing objects. A large number of mechanical appliances and equipment are often used in fully enclosed construction, such as graders, rollers, milling machines, seam cutting machines, temporary electricity facilities, etc. The use of these machines is both professional and complicated. If the operation is improper or not strictly in accordance with the prescribed procedures, it is easy to cause machine injury accidents, and the mortality rate of such accidents is high, and the consequences are often very serious. For example, in the construction of Xi 'an municipal road in 20 13, a roller overturned at the end of subgrade filling operation, causing one death. During the construction of this project, after the project leader assigned the task, he verbally stipulated that after the machinery enters the ditch, it is not allowed to start the machinery to add water, refuel and maintain. Generally, the operation is completed at the bottom of the ditch. However, the driver did not operate according to the regulations and drove the roller up privately. In the process of climbing, the roller lost power and slipped, and finally overturned. The driver was stuck in the chest by the steering wheel and died on the spot. It took only five minutes from the accident to the driver's death. The safety hazards in semi-closed construction are not only prone to the above-mentioned safety accidents of construction personnel and machinery, but also may cause injuries to personnel and vehicles due to unreasonable traffic diversion and enclosure. In order to avoid the occurrence of safety accidents and minimize the rate of safety accidents, it is necessary to strengthen the safety management in municipal road construction.

Third, the current situation of municipal road construction safety management

At present, the present situation of safety management of municipal road construction in China is not ideal, and the management effectiveness is poor, which can not effectively play the role of safety management. Judging from the causes of safety accidents in municipal road construction in recent years, many engineering projects have not taken effective management measures and paid insufficient attention to safety management, which is often a mere formality. The importance of leaders often determines the quality of work. In the management of municipal road construction, there are many phenomena of "emphasizing production over management", mainly because leaders are too lucky to ignore safety management, and there is no corresponding safety management mechanism, safety management scheme and strategy. Lack of on-site management, unclear safety management objectives, unscientific, imprecise and unreasonable safety management process, and poor effectiveness of safety management. In addition, even some municipal road projects have not set up safety management functional departments. In order to save money, personnel from other departments are temporarily transferred to supervise, and the management organization form and structure are very imperfect, lacking professional safety management personnel. These temporary safety managers not only lack a sense of responsibility, but also have not received systematic safety management knowledge training, and their comprehensive quality is uneven. Some personnel lack the corresponding skills, can't work smoothly, and can't be competent for their posts, which is also the main reason that affects the safety management effect.

Four, effective measures to strengthen the safety management of municipal road construction

The occurrence of safety accidents in municipal road construction will cause economic losses, endanger the life safety of construction personnel and surrounding personnel, affect the overall construction progress, and it is of great significance to do a good job in safety management. The following is an analysis of effective measures to strengthen the safety management of municipal road construction: 1. To build a safety management system, we must build a corresponding safety management system, set up a safety management functional department, and be fully responsible for the development of safety management. Construction functional departments should combine the characteristics of safety management and construction site management to formulate detailed safety management plans and strategies. In addition, the formulation of safety management system can provide a basis for the smooth development of safety management, restrain the behavior of safety management personnel and construction personnel, and enhance the sense of responsibility of all construction personnel. In view of the problems existing in the current safety management, the safety management system is formulated and constantly improved, the safety management behavior and construction behavior are standardized, and the system is used to ensure the continuity and effectiveness of safety management. 2. Improve the comprehensive quality of managers. Municipal road construction safety management involves a lot of professional knowledge, which requires high comprehensive quality of managers. If managers themselves have no safety awareness and knowledge, they cannot play their safety management functions. Therefore, while introducing advanced management talents, we should also strengthen the training of existing personnel, optimize the talent structure, improve the quality of management personnel, enable them to master safety management skills and theoretical knowledge, and lay a foundation for the development of safety management. 3. Establish a "self-examination and self-correction" mechanism and cooperate with relevant departments to do a good job in traffic guidance. Construction enterprises must strengthen on-site safety management, establish correct safety management awareness, publicize safety knowledge, organize construction personnel to learn safety knowledge and skills, improve the safety awareness of all personnel, and put safety production in the first place. Establish a "self-examination and self-correction" mechanism to conduct self-examination and self-correction of potential safety hazards existing in the construction site, take site management as the focus of safety management, set up reasonable traffic guidance, warning and warning signs according to the requirements of the specification, and actively assist the traffic management department to do a good job in temporary traffic guidance. 4. Establish a supervision and inspection mechanism, give full play to the supervision function of project supervision, establish a supervision and inspection mechanism, improve the quality of safety management through supervision and inspection, and further eliminate all kinds of safety hazards. During supervision and inspection, the site shall be thoroughly inspected. If potential safety hazards are found, they must be rectified in time. If violations are found, they should be dealt with seriously to ensure the effectiveness and seriousness of safety management.

Safety in production is very important, and municipal road construction must be well managed to reduce the construction safety accident rate. At present, many municipal road projects do not pay attention to safety management, which leads to frequent safety accidents. Therefore, in view of the problems existing in current management and the characteristics of municipal road construction, it is imperative to take effective safety management measures and strengthen construction safety management.
