Safety measures for highway overhaul project construction?

Highways are safe and fast and play an irreplaceable role in ensuring smooth transportation and promoting social development. However, due to the impact of overloading and increased transportation pressure, highways also need to be repaired and maintained, and it is unrealistic and difficult to implement major repairs that interrupt traffic. Therefore, it is of positive practical significance to explore measures for safe and smooth construction of highway overhaul projects.

1 Establish a construction safety and smoothness management organization

In order to ensure safe and smooth traffic during the construction of highway overhaul projects, the construction unit needs to establish a construction safety and smoothness management leading group, with the composition of the team members and Responsibilities are as follows: the team leader is the project manager, fully responsible for the formulation and implementation of various safety and smoothness measures during highway construction; the deputy team leader is the deputy project manager and chief engineer, mainly responsible for guiding the development of various safety and smoothness work; The team members are the heads of various departments and relevant managers, and are mainly responsible for implementing various safety and security measures and coordinating various work links [1]. To meet the needs of actual work, the construction site needs to arrange smooth flow personnel and traffic guidance personnel to manage traffic flow at the construction site, and report traffic conditions and traffic information in written form to provide a basis for planning safety and smooth flow measures. Regardless of the person in charge of maintaining smooth flow at the construction site, or the traffic conductor and safety officer, safety training is required before the construction of the highway overhaul project begins. Only those who pass the assessment and obtain a safety qualification certificate can take up their posts. During the entire construction period, the safety and smoothness management leading group adopts a rotating duty system to ensure that responsible leadership is available 24 hours a day so that timely measures can be taken after problems occur.

2 Do a good job in information announcement and publicity work

Before starting the overhaul construction of the highway, the construction unit needs to do a good job in information announcement and publicity work so that passing vehicles and the surrounding people can learn about the construction in a timely manner information, so as to adopt appropriate travel methods, relieve traffic pressure on highways, ensure safe and smooth roads and create favorable conditions. The construction unit can take the following measures: ① Make construction information cards, distribute them at the toll gates of the highway, and make reminder banners to hang in prominent positions at the highway toll stations to facilitate the spread of construction information; ② 15 days before construction, with the help of traffic radio, Internet platforms and TV and other media publish notices about the upcoming construction of highways to let passing vehicles know the information and choose appropriate passing times; ③ Release construction section information through the management office to remind passing vehicles to strictly abide by the instructions and regulations when passing, and slow down to pass. Ensure safe and smooth driving; ④ Carry out safety publicity in villages, towns and schools along the expressway to enhance villagers' safety awareness and avoid safety accidents [2].

3 Strengthen traffic supervision over construction vehicles and construction personnel

In order to shorten the construction period and minimize the adverse impact on traveling vehicles and surrounding people, highway overhaul construction is generally 24 hours non-stop operation. In order to ensure safety and smoothness during construction operations, local governments need to strengthen traffic supervision of construction vehicles and construction workers to avoid illegal operations and traffic accidents. At the same time, the construction unit needs to arrange debris removal vehicles to ensure the smooth progress of road construction.

4 Pay attention to the joint coordination with the road administration and traffic police departments

During the highway overhaul construction, the construction unit needs to pay attention to the work-to-work coordination with the road administration and traffic police departments in order to In the form of joint logistics, we regularly hold discussions and exchanges with them in order to monitor the construction status and traffic conditions of the expressway and create favorable conditions for the smooth construction of the expressway. At the same time, if a traffic accident occurs on the construction section of the expressway, resulting in traffic jams, the construction unit needs to promptly notify the expressway traffic police management department so that they can rush to the scene to rescue the injured as soon as possible and adopt traffic control through vehicle diversion and temporary passage. Various diversion measures such as changing lanes to avoid long-term congestion. During the period of diverting vehicle traffic, the traffic police department and the road administration department need to quickly inspect the accident site, direct the vehicles to tow and remove obstacles, so as to restore road traffic as soon as possible, and report the situation at the accident site to the superior management department in writing.

5 Carry out training for road administration personnel and construction personnel

Before the highway overhaul construction begins, the traffic police department and the road administration department need to organize the construction unit’s on-site smooth maintenance personnel and safety personnel to conduct Provide training to let them understand the relevant contents of the Traffic Safety Law, relevant regulations and precautions in construction management, improve their safety awareness and sense of responsibility, and require them to obtain safety qualification certificates before they can work on the job to ensure that they are safe at work Follow traffic laws and standardize work and construction.

6 Implement protective measures for construction safety and smoothness

To ensure safety and smoothness during highway overhaul, implementing protective measures for construction safety and smoothness is the top priority. The construction unit can cooperate with the traffic police department and road administration department to start from the following aspects. ⑴ The right half of the highway will be closed, only the left half of the road will be allowed to open to traffic, and signs in the construction area will be set up in accordance with the "Highway Safety Maintenance Operation Regulations". ⑵ Set up warning banners 5km ahead of the construction section, and set speed limit signs of 20km/h at 2km, 1.6km, 1.2km, 1km and 0.8km; set a speed limit limit 0.6km ahead of the construction section. High mast; 450m in front of the construction section, set up signs indicating slow driving, driving in the traffic lane and no overtaking; 60m in front of the construction section, set cone signs with an interval of 5m; 10m in front of the construction section A certain number of sandbag piles and barrier strips are set up to buffer out-of-control vehicles. ⑶ In the construction section and the diversions with openings on both sides, the construction unit needs to arrange for dedicated personnel to work 24 hours a day to direct traffic with hand flags. At the same time, a diversion sign should be set up at the diversion with openings on both sides. The diversion sign should be 500m away from the construction section. The sign must comply with the maintenance standards of the highway [3]. ⑷ Protective measures to ensure smooth flow at night. First of all, construction workers need to wear uniforms. The work suits are orange and have reflective markings. Construction workers on and under the bridge need to wear safety helmets correctly. Construction vehicles need to have uniform reflective markings to facilitate identification during night construction. Secondly, during night construction, the construction site needs to be equipped with white light lights, which cover the entire work area. Construction warning lights need to be set up in nighttime construction work areas, and traffic signs need to have light-proof functions. During and after construction, the construction unit needs to arrange dedicated personnel to be responsible for the management and maintenance of lighting facilities. Thirdly, the construction unit needs to set up strobe lights 1.6km away from the front and rear of the construction area, and strobe lights need to be set up at the diversion crossing to keep them in working condition at night, and have safety personnel pay attention to observe their operation during night patrols. Is it normal? If any problem is found, it needs to be reported immediately to avoid traffic accidents. Finally, at the diversion with openings on both sides, the construction unit needs to arrange for on-duty personnel to direct the passage with hand flags and fluorescent sticks, and implement a 24-hour rotation system to ensure smooth operation of the road transportation hub.

7 Develop effective construction environmental protection measures

In the construction closed section of the highway, the construction unit needs to set up a 2m high color steel plate fence around it, and the project introduction needs to be hung on the front , safety warnings and corporate promotion slogans. The bottom of the color steel plate needs to be surrounded by colored strips of cloth to prevent construction soil from entering the adjacent traffic lane, thereby polluting the environment around the construction area and affecting the normal life of the people around the construction area [4].

8 Conclusion

In short, during the highway overhaul construction period, the construction unit needs to coordinate with the road administration department and traffic police department to establish a construction safety and smoothness management organization and make information announcements and publicity work, strengthen traffic supervision of construction vehicles and construction personnel, focus on joint work with road administration and traffic police departments, carry out training for road administration personnel and construction personnel, implement protective measures for construction safety and smoothness, and formulate effective Environmental protection measures during construction will be taken to ensure safety and smoothness during highway construction and to minimize the adverse impact on passing vehicles and people around the construction area.
