1 Introduction
With the rapid development of highway construction in China, the mileage of highway traffic has increased rapidly, and the number of bridges has also increased. Strict and orderly management of bridge construction, energy saving and consumption reduction, laws to follow, and harmony between labor and capital are of great significance to the success or failure of national infrastructure construction and are compulsory courses for general construction units. The progress and quality of the project is the most important project. Safety is another core issue of highway and bridge construction projects. The project should carry out production activities in strict accordance with the principle of national security first and priority. Safe development? 、? People-oriented? Safety concept. It can be seen that safety construction is the most concerned issue in engineering construction. Quality management is closely related to safety management, and lax quality will lead to quality and safety accidents, and its loss and maintenance will be enormous.
2. Establish perfect construction safety management measures.
In the process of construction, construction workers will feel unsafe because of external factors and their own factors. External factors mainly include factors, environmental factors and labor management methods. Therefore, it is necessary to comprehensively analyze the negative emotions of construction workers in different environmental conditions and eliminate their negative psychological emotions. This requires grass-roots managers to go deep into the surroundings of construction workers in the daily construction process, observe and collect the situation of construction workers, and discover their psychological changes in time, so as to reduce the operational safety problems caused by the emotional problems of construction workers. Arrange rest time reasonably to prevent overwork. Because of the heavy work intensity and workload of the construction personnel, it is necessary to arrange the rest time of the personnel reasonably and timely.
3. Establish a perfect construction quality assurance system.
3. 1 Improve the reward and punishment system and improve the enthusiasm of employees. The project manager should establish a reward and punishment system for project quality supervision and improve the corresponding reward and punishment system. Punish accidents caused by illegal operation, quality concealment, fraud, AWOL, etc. In the process of engineering construction; People or teams who are active and serious in their work and prevent major accidents in advance should be commended and rewarded to improve the sense of responsibility of employees in their serious work.
3.2 Do a good job of maintenance. Mechanical maintenance should be carried out by relevant professional technicians under the auxiliary management, and the mechanical operators should cooperate and supervise. In daily operation, they should carefully observe the machine, check it three times a day, carry out basic maintenance on the equipment and operate it carefully.
4. Analysis of the present situation and existing problems of bridge construction safety management
The fierce competition in bridge construction makes contractors pay more attention to bidding, construction and cost control, ignoring the safety management in the construction process, which leads to potential safety hazards in the bridge construction process. In addition, a considerable number of enterprises manage the equipment necessary for safe construction in order to save, which leads to the increase of bridge construction site safety and seriously endangers the personal safety of construction personnel. At the same time, most front-line workers in China's construction market are migrant workers, lacking necessary safety knowledge training, and illegal operations will inevitably occur during the construction process, which is also an important factor leading to bridge construction safety accidents.
5 scientific implementation of bridge engineering construction safety management
5. 1 according to the actual situation of enterprises and projects, build a perfect construction safety management system.
The construction and improvement of bridge engineering construction safety management system need to be scientifically analyzed in combination with the actual situation of enterprises and projects, so as to promote the improvement of safety management system. According to the enterprise safety management facilities, relevant personnel composition and key areas of safety management in the actual development of the project, a perfect construction safety management system is constructed to ensure the pertinence and applicability of the safety management system and promote the scientific development of safety management in the bridge construction process. At the same time, bridge construction enterprises should also strengthen the inspection and purchase of their own safety protection facilities, and replace damaged and unusable safety protection facilities in time to ensure the safety of construction personnel.
5.2 Improve the safety management framework according to the actual situation of the enterprise.
In state-owned enterprises or large-scale construction groups, the foremen of the first-line operators in the construction organization are full-time employees of the enterprise, and these employees have received relevant safety technical training in the enterprise, so they can supervise and manage the safety operation and safety construction of the subordinate first-line operators in actual operation. Therefore, the safety responsibilities of foremen can be appropriately increased in the safety management system of such enterprises to promote the development of building safety management. For general construction enterprises, they do not have the conditions to employ professional operators for a long time, which requires them to give more safety management responsibilities to the on-site technicians and quality management personnel. This requires enterprises to proceed from their own reality, improve the safety management framework, and ensure the development of safety management with clear safety responsibilities.
5.3 according to the quality of construction personnel, strengthen safety training.
Because the front-line workers in bridge construction are mostly migrant workers nearby, they lack safety awareness and related training. Bridge construction enterprises should strengthen the cultivation of safety awareness of construction personnel, strengthen the on-site supervision mechanism, and promote the development of workers' safety protection. Although under modern conditions, training workers will increase the expenditure of labor costs to a certain extent, on the other hand, it will also reduce the expenditure of enterprise safety accident handling expenses. When the construction cannot be carried out due to weather factors, safety training can be arranged at intervals to achieve the purpose of not affecting the construction period and keeping workers busy in rainy days. Through safety training, cultivate the safety awareness of frontline construction personnel and reduce the occurrence of safety accidents.
5.4 Strengthen safety facilities to ensure the safety of construction personnel.
For the safety protection facilities used in the bridge construction process, the construction enterprises should also check them regularly to ensure that they can achieve the purpose of safety protection and ensure the safety of construction personnel. Regular calibration can effectively reduce the casualties caused by safety rope breakage and ensure the safety of construction personnel during construction.
5.5 Strengthen the management of construction site equipment
Precast structures are mostly used in bridge construction, and they are hoisted on site. During the construction, there are many facilities such as large lifting equipment. In the actual construction process, the site technicians and quality management personnel of construction enterprises should pay special attention to the safety management in the hoisting process and strictly implement the relevant safety rules and regulations. By strengthening the management of construction site equipment, the development of construction safety management can be effectively guaranteed.
5.6 Pay attention to the management of related contents of temporary electricity utilization on site.
With the popularization of modern buildings, generators or temporary power lines are often used in bridge construction to supply construction equipment and domestic electricity, which is also the focus of modern bridge construction safety management. For example, the manual arc welding equipment commonly used in the construction process mostly adopts its own gasoline and diesel generators. However, the spark generated in the process of shielded welding is easy to ignite fuel. Therefore, after adding fuel, the fuel storage tank should be transported to a safe designated storage place in time to reduce the occurrence of fire accidents caused by sparks.
6. Pay attention to the maintenance and management of construction equipment and improve the safety management effect.
In the process of modern bridge construction, safety hazards or accidents caused by construction equipment failures often occur. Therefore, modern bridge construction safety management should fully consider all factors that affect construction safety, strengthen the management of safety factors that are not recognized in traditional safety management, and effectively improve the implementation effect of safety management. Through various safety management work, the occurrence of construction safety accidents can be effectively reduced and avoided.
7 concluding remarks
As can be seen from the above discussion, the safety management of bridge engineering construction is a systematic work, involving many aspects of construction, which requires enterprises to improve the management system. Modern bridge engineering construction enterprises should strengthen the investment in safety management, strengthen personnel training and on-site management, and pay attention to the control of various factors affecting construction safety, so as to achieve the fundamental purpose of safety management. Modern bridge construction enterprises should correctly understand the dialectical relationship between safety management input and safety treatment cost, so as to increase safety facilities and management input, reduce the treatment cost after safety accidents, reduce the impact on the safety of construction personnel, and effectively improve the economic benefits of enterprises.
