Northeast China, the earth is still covered with white snow, and there is a little biting cold in the wind. In the Wudaoling Tunnel in the 02 work area of Huanren-Ji'an Expressway in Liaoning Province, the builders are busy and orderly, and their ears are filled with the roar of machinery and equipment.
"Not cold!"! The project department has equipped our dormitory with heating, and the tunnel has also installed thermal equipment to ensure the temperature of the operation in the tunnel. There is ginger soup to drink every day, and the construction is guaranteed in the cold season. Yin Longxuan, a construction worker at the site, introduced. During construction in
cold weather, how to ensure the temperature of concrete has become a key issue in project construction. In view of the low temperature, the project department specially builds a new boiler in the mixing station, and the hot air of the boiler heats the raw materials and mixing water of the mixing station through a special pipeline to ensure the quality of the concrete. Li Yanfeng, head of Huanji Expressway Project Laboratory, introduced that the concrete tanker was covered with special thermal insulation tarpaulin, the entrance and exit of the tunnel were equipped with thermal insulation door curtains, and the laboratory arranged special personnel to measure and record the concrete out of the machine, into the mould and maintenance, so as to ensure that all processes meet the requirements.
In order to fully guarantee the construction period, the project department of the 02 work area of Huanji Expressway has reversed the construction tasks, sorted out the remaining construction volume, refined the tasks to weekly and daily, and decomposed them into working teams and teams layer by layer, so as to effectively and orderly promote the project construction and fully guarantee the smooth opening of the project this year.
It is understood that Huanji Expressway is 258 kilometers long, with three bidding sections in Ji'an City, Jilin Province, with a main line mileage of about 57.7 kilometers, 35 bridges and culverts and 11 tunnels. This year is the closing year of Huanji Expressway, which is expected to be completed and opened to traffic by the end of September. At that time, the time distance between Tonghua and Liaoning Coastal Economic Zone will be further shortened, which will play an important role in promoting Jilin Province to better open to the south and integrate into the Bohai Economic Circle.
