On December 30, the northern section of Beijing Metro Line 17 was opened, connecting large residential areas such as Tiantongyuan and Taiyanggong as well as commercial areas such as Sanlitun. A few days before the opening of traffic, the Taiyanggong Station of Metro Line 17 took the lead in welcoming a group of special passengers - subway builders from the 07 bid of Line 17 of the Second General Contracting Department of Beijing Municipal Road and Bridge. They gathered inside the station and took a group photo with the station they had built.
On the morning of December 26, the builders came to the brand-new subway station, held up the slogan "Warmly celebrate the successful completion of the Taiyanggong Station of Line 17 07", and took a group photo. Many people have experienced the entire construction process of the project for nearly five years, and they are very emotional about every brick and tile of this station. In the station full of "warm sun" elements, the builders raised their mobile phones to take pictures, and a unique flower awarding ceremony was held on the spot, and bursts of laughter came from the station.
The project was finally delivered on schedule, ensuring that Line 17 was opened to traffic on time, and the mood was surging!Zhao Ying, the project manager of Line 17 07, who wore a big red flower, sighed with emotion and smiled from ear to ear. He introduced that the length of the 07 standard line of Beijing Metro Line 17 is about 117 kilometers, including "one station and one section": the section between Taiyanggong Station and Xibahe Station and Taiyanggong Station of the Metro Metro includes 1 special risk source, a total of 57 first-level risk sources, and 96 first-class risk sources, with a total of 154 risk sources, which is equivalent to an average of every 18 meters in the district, and an average of one risk source needs to be crossed every 10 days during the construction of the station, which is one of the most difficult projects in the construction of the whole line.
Among them, Taiyanggong Station is a "special risk source", and the bid section will pass through the existing Taiyanggong Station of Metro Line 10, which is one of the most challenging construction technology sources in the project. According to Zhao Ying, according to the typical geological characteristics of Beijing's water-rich sand layer, the project department transformed the cutterhead of the shield machine by equipping special pile grinding tools, controlled the settlement of the existing line through advanced technology, and successfully crossed the Taiyanggong Station of Metro Line 10 in operationAt 58 mm, less than the thickness of a fingernail, it is almost zero-distance traversal.
It is understood that after the opening of the northern section of Line 17, it will only take 31 minutes from the north of the future Science City to the Workers' Stadium. The northern section of Line 17 starts from Changping District in the north to Chaoyang District in the south, with a total length of about 25 kilometers and a total of 10 stations, from north to south, they are Future Science City North Station, Future Science City Station, Tiantongyuan East Station, Qingheying Station, Hongjunying Station, Wangjing West Station (temporarily suspended), Taiyanggong Station, Xibahe Station, Zuojiazhuang Station, and Workers' Stadium Station. Among them, Taiyanggong Station is the interchange station between Line 17 and Line 10.
