With the rapid development of social economy, the scale of urban population has risen rapidly. Therefore, the construction of road infrastructure has also become the key to the urban development process. At present, China has listed highway construction as an important part of national construction and attached great importance to it. However, there are still many problems in highway construction management, which have laid a great hidden danger for highway construction safety. Highway engineering is closely related to people's life and work, and construction safety must be ensured. Therefore, combining with the actual construction and management experience, this paper puts forward specific methods and measures for related problems.

First, the status quo of highway construction safety management

At present, with the continuous expansion of industry competition, the benefit distribution and management mechanism of construction enterprises have changed greatly. At the same time, it also brings great obstacles to the safety management of highway construction.

1, safety construction characteristics of highway engineering

In highway engineering construction, it can be seen from relevant construction data that production safety accidents mainly include falling from a height, collapse, object strike, mechanical injury, electric shock and so on. And the frequency of these accidents is very high, even more than 80%. These accidents mostly occurred in bridge construction and tunnel construction, which caused serious economic losses to enterprises.

2. Problems existing in highway construction safety management

First of all, enterprises do not attach importance to production safety. In the process of construction, we often attach importance to economic benefits and neglect construction safety management, thus increasing construction risks. Secondly, the investment in safety production costs is insufficient. If the investment in safety protection is reduced, relevant protective measures are not taken when working in high-risk environment (high altitude, deep foundation pit and tunnel), resulting in production safety accidents. Thirdly, due to many links in highway construction and heavy workload, temporary construction workers are often employed. These personnel are mainly from rural areas, lacking relevant construction safety knowledge and safety training, and unable to meet the construction requirements. Finally, the safety management system is not perfect. Usually, the safety management system formulated by the project department is mainly to cope with the inspection, which is inconsistent with the actual situation of the project and has no practical feasibility, resulting in the system construction becoming a mere formality. At the same time, coupled with the lack of sense of responsibility of relevant managers, resulting in a regulatory gap.

Second, measures to improve the safety management level of expressway construction

1, highway construction organization and management improvement measures

First of all, establish a perfect safety production guarantee system. At the same time, in order to ensure the implementation of relevant responsibilities, we should also establish the necessary responsibility system for safety production. Secondly, the responsibilities of various departments and personnel are clarified through the method of post allocation. On this basis, the assessment system of safety production responsibility is established. In the process of highway construction, the safety control of dangerous "sub-projects" should be strengthened in strict accordance with the goal of safe production. Finally, strengthen the supervision and management of the construction site. In highway construction, provide necessary safety protection articles for construction personnel and require them to wear them as required. If the construction personnel who do not comply with the above provisions are found, they should be severely criticized and punished to serve as a warning. In addition, in the construction of bridges and tunnels, necessary safety protection measures should be taken to ensure the safety of construction personnel. In addition, relevant personnel should strengthen the quality supervision of each construction link, discover potential safety hazards in time and eliminate unsafe factors.

2. Improve the safety quality of highway construction employees.

First of all, safety management personnel should be regularly trained in safety education knowledge to improve their safety awareness. At the same time, let people with rich knowledge of safety production and on-site management experience play a leading role and improve the quality of others. Secondly, although some construction workers are experienced, they lack knowledge of construction management. Therefore, it is also necessary to strengthen the training and education of these personnel and expand their professional knowledge reserves, which will not only improve the construction skills and level. Finally, for the field staff, more attention should be paid to the training of construction skills and safety education. Through effective knowledge training, the construction skills and safety awareness of operators are continuously improved, and finally the construction safety of highway engineering is guaranteed.

3. Increase investment in safety construction equipment.

First, strengthen the inspection and maintenance of equipment. Once the equipment is found to have problems, it should be repaired in time. For the equipment that cannot be repaired for many times, it is necessary to contact the manufacturer in time to replace or directly eliminate it. Secondly, set up necessary safety signs and warning signs at the construction site to attract the attention of operators. Finally, according to the actual situation of the project, advanced mechanical equipment is introduced to improve work efficiency and reduce the occurrence of construction safety accidents.

4. Improvement of building working environment

First, reduce the harm caused by productive dust and noise. In highway construction, there are many dust operations, which are harmful to people's health. Therefore, a strict dust measurement system must be established, and the dust content should be detected by relevant technicians, and then the working conditions should be continuously improved according to the detection results. In addition, advanced technical measures, such as wet operation, can be adopted to reduce dust flying, thus reducing environmental pollution. In addition, equipment with low vibration and noise can be selected to reduce noise. Secondly, under the condition of high temperature operation, certain measures should be taken to improve the construction environment, such as adjusting the construction period, giving the construction personnel adequate rest, providing bathing and fan lighting equipment, etc. Finally, before highway construction, it is necessary to survey the construction environment, master the local hydrogeological characteristics, and strictly formulate the construction plan. At the same time, in the process of construction, construction must be carried out in accordance with the construction plan, and the plan cannot be changed at will.

At present, the scale of expressway construction in China is constantly expanding, which brings great convenience to people's travel. But at the same time, due to the chaotic construction management, backward equipment and low quality of personnel, it has caused great security risks to highway construction management, and the construction quality is difficult to guarantee. Therefore, in view of the above problems, it is necessary to improve the relevant management system, increase the investment in safety production costs, and continuously improve the comprehensive quality and construction skills of relevant personnel. Only in this way can we reduce the safety accidents in construction and finally ensure the safety of highway construction.
