Looking at the great power and heavy equipment to build the "Yangtze River Delta on track"

On December 12, the last underground Yuhang high-speed railway station in the whole line of Hangzhou Haikou intercity railway, yuxu section U-shaped groove (excluding) shield tunneling project, was completed as the huge shield cutter slowly rotated to break through the earth. So far, nine underground tunnel sections of Hangzhou Haikou intercity railway of Zhejiang communications group have been completed, and the "tunnel connection" has been successfully realized. "Dongtong" of the whole line is another important node of Hangzhou Haikou intercity railway after "Qiaotong" of the whole line on August 2, 2019. It marks that the construction of Hangzhou Haikou intercity railway has stepped into a new stage and opened a comprehensive construction period for the construction of connecting channels and tracks in the tunnel.

, China has maintained rapid development, with its total economic output jumping to the second place in the world, and its manufacturing scale leaping to the first place in the world, creating an economic miracle in the history of world development. Thanks to the historical opportunity of China's large-scale infrastructure construction, China has become the world's largest production and marketing country of construction machinery, and the construction machinery made in China has moved to all parts of the world. After years of rapid development, the scale of China's construction machinery industry has occupied 30% of the world market share. A 6031 a 6031 China's current railway construction is a bridge in the water. Infrastructure connectivity is an important part of China's belt and road initiative. With the continuous promotion of the initiative, a series of major infrastructure projects have been put into operation all over the world, and a batch of new machinery has played a role in the rapid development of the "belt and road" construction.

since May 8, 2018, 9 shield machines of Hangzhou Haicheng inter city railway have been used to open the underground tunnel construction for nearly 580 days, finally ushering in the completion of the whole line. During the construction process, the project team has overcome many construction technical problems, such as the shield passing through the second channel of the planned Beijing Hangzhou canal, the long-standing shallow foundation special building group, the gas section, the small clear distance of the shield passing through the operation Metro Line 1, and the shield receiving of the full section water rich silty sand stratum near the Metro Line 1.

in recent years, China is known as ” infrastructure maniac, which originates from a series of large-scale infrastructure construction and super projects in recent years. Ten years ago, when I heard about China's high-speed rail plan, I was excited. With the rapid development of China's high-speed railway in the past ten years, China's railway has gone through an unparalleled growth path, which is inseparable from the bold breakthrough and determined innovation of several generations of Railway Science and technology workers. The railway builders will gather strength with confidence, compose new articles with practical work, and make unremitting efforts to build the "Yangtze River Delta on the track" with solid steps and real construction achievements!
