On September 22, the first rail express line of Hangzhou, which participated in the 22nd Railway Railway, was officially opened to operation. On the same day, Hangzhou Metro Line 3 north extension section (Wushan Qiancun Station-Longzhou North Road Station) and Line 10 Huanglong Sports Center Station also opened operations. At this point, the operating mileage of Hangzhou Metro Line has reached 516 kilometers, and it has chased first -tier cities such as north, Shanghai, and Chengdu, and ranked fifth in China.

As a rail express line through the central city of Hangzhou and the main axis of the city, Line 19 connects the Hangzhou Chengxi Kochi Corridor and the Chengdong Intelligent Corridor. To this end, the rail express line uses a large station spacing and uses the highest operation to run the highest operation. Vehicles with a speed of 120 kilometers per hour can cross the entire Hangzhou city about 50 minutes after completion. After opening, it will connect the three major transportation hubs of Hangzhou Railway West Station, East Railway Station, and Xiaoshan International Airport at the same time, which will play an important role in serving Hangzhou's urban spatial pattern, strengthening east -west wings and main cities.

The 07 -standard section shield interval responsible for the 22nd Railway Railway Railway is the project with the largest difficulty and the most risk sources in the entire line. It is only 4.58 meters away from the nearest distance of Metro Line 4, especially the shield machine requires secondary starting. Hair, tight construction period, difficulty in process, high requirements. They strengthened scientific and technological research, carefully organized, scientific construction, and innovatively used the "double insurance" measures of "frozen method+steel box" to achieve shields throughout the board. In addition, the technical group used the "gram mud effect" method from abroad to make the shield construction settle within 2 mm.

The technical team of the project department also uses bridge prestressed intelligence tensor in the construction of elevated interval projects to achieve intelligent control of prestressed tensor programs to ensure the quality of paddling beams. They continue to innovate, and use the informationization methods such as the dungeon cloud and the real -time monitoring system of the construction site to realize the visualization of online surveillance online to ensure the safety production of the project.

According to the project manager Zhou Xiaofeng, as the first rail express line in Hangzhou, the 59 -kilometer Hangzhou Metro Line 19 starts to Xixi Station and ends at Yongsheng Road Station. There are 15 stations on the entire line. Stand, 120 kilometers per hour. This line is a functional composite express line that takes into account the recent passenger flow service and long -term development. It is also the only subway line in Hangzhou Metro that adopts the river crossing the river, which has realized the "stepping waves".

It is reported that at the same time that it was put into operation at Line 19, Hangzhou Metro Line 3 north extension section (Wushan Qiancun Station-Longzhou North Road Station) and Line 10 Huanglong Sports Center Station also opened simultaneously. With the opening of these three lines, the Hangzhou Metro -Phase III Line Network is all connected, which not only makes Hangzhou Metro's operating miles jumping for fifth in the country, but also realized "Hangzhou on the track".
