Speeding up the implementation of national and provincial trunk highway maintenance in our city
Recently, in the construction site of the maintenance project of Jiazhuang Village section of the provincial highway Niangyang line, milling machines, sweepers and other machinery are carrying out operations such as road milling and drainage ditch protection, laying a good foundation for subsequent construction. This is a microcosm of speeding up the implementation of national and provincial trunk highway maintenance projects and continuously creating a safe and smooth traffic environment in our city.
As an important part of the comprehensive transportation system, national and provincial trunk highways play a fundamental and leading role in promoting economic and social development and improving people’s livelihood. In recent years, our city has continued to promote the construction of people’s livelihood transportation, aiming at creating a "smooth, comfortable and beautiful" highway traffic environment, vigorously implementing domestic national and provincial trunk highway maintenance projects, constantly improving highway traffic capacity and comprehensive service level, and providing strong highway support for the city’s economic development.
With the increase of the service life of national and provincial highways and the increasing number of large transit vehicles in our city, the existing pavement has been damaged to varying degrees, and the preventive maintenance of pavement is imminent. As a provincial key project newly started in our city this year, the road maintenance project of Shuiyu-Majiapo section of provincial highway Niangyang line has a total length of 25.2 kilometers and a total investment of 160 million yuan. The starting point of the project is Shuiyu Village, Jucheng Town, Pingding County, which is connected with the first-class highway around the city of National Highway 207 and 307 in our city, and the end point is Majiapo in the suburbs, which is connected with National Highway 307. The highway runs through Pingding county, suburbs and mining areas, and is an important part of the "four verticals, five horizontals and two cycles" national and provincial trunk highway network in our city during the 14 th Five-Year Plan period.
Wei Jinfeng is the project manager of pavement maintenance project in Shuiyu-Majiapo section of Niangyang line of Shanxi Luqiao Provincial Highway. When he came to the construction site, he and the engineers and technicians kept an eye on the construction quality and progress. Wei Jinfeng introduced that since the project started, the project department has always adhered to the principle of "taking quality as the core, taking safety as the premise and taking progress as the goal" and comprehensively and orderly promoted all work. Because the construction section is long, involving many factories and mines in villages and enterprises, in order to ensure the normal production and life of villagers and enterprises, the project department takes control measures such as handling permits to advance the construction progress in an orderly manner on the premise of ensuring safety.
During the construction, the construction party shall carry out functional and structural repairs on this section, control local pavement diseases synchronously, build a new central guardrail, improve the electromechanical facilities of the tunnel and drainage facilities along the line, etc., involving the asphalt pavement structure of the section, drainage, culverts, tunnels, traffic safety facilities and other construction projects along the line. According to the first-class highway design standards, the subgrade width is 23 meters and the design speed is 60 kilometers per hour.
Guan Bo, deputy director of the Maintenance Engineering Construction and Management Department of Yangquan Highway Branch, said that this section and the first-class highway around Yangquan City on National Highway 207 and 307 jointly form the first-class highway around Yangquan City, which is the central axis and connecting line in the two cycles of north and south, which is of great significance for widening the urban framework and promoting the development of towns along and around it. All construction personnel will scientifically optimize the construction period, reasonably organize the construction, and advance the construction progress at full speed.
At present, many national and provincial trunk highway maintenance projects in our city have started construction one after another, with large investment, long route and many spanning areas. Faced with the grim situation of tight time and heavy tasks, Yangquan Highway Sub-bureau planned, arranged and started early, scientifically decomposed tasks around the overall goal of progress, grasped key working procedures and ensured key parts, formulated targeted construction plans, accelerated the construction progress and ensured the project was completed on schedule on the premise of ensuring quality and safety.
Guan Bo said that after the completion of the project, it will further extend the service life of the national and provincial trunk highways in our city, ensure driving safety and help the high-quality economic development. (Feng Mengqi, Zhang Yaoguang)
