With the booming noise of the tunnel boring machine at the Lijiang Road Station of the Rail Transit No.4 on April 23, the section of the line between the Zhuangqiao Station to the Lijiang Road Station was completed smoothly. The completion of this first TBM section of the Rail Transit No.4 represents the successful resolution of the biggest risk spot of the line.
So far, the construction of all the 25 stations of the lien has been started, with that of the Dongqian Lake section and three other TBM sections well under way.
The TBM section between the Zhuangqiao Station to the Lijiang Road Station is 1208.1 meters long on its right line and 1342.3 meters on its left line. With such risk sources as the Xiaoshan-Ningbo Railroad, the Hangzhou-Shenzhen High-speed Railroad, the Baisha Branch of the railroad and ground source heat pumps, this section regarded as the part of the line with highest concentration of security risks. Reportedly, the Zhuangqiao Station of the railroad above the line receives 264 trains each day, posing great difficulty to the construction process.
To address the problem, Ningbo Rail Transit has optimized the construction plan and invited experts to supervise the control of the constructing process, thus keeping the maximum daily sedimentation within 0.3 millimeter. The TBM section has been under construction even during the Spring Festival period, and so it was completed on month ahead of schedule, with the tunnel usability rate standing above 95%.
The Dongqian Lake section of the line, starting construction on April 3, is also an important part of the whole project. The major tasks of the section include the soft base treatment, house building, the electromechanical equipment installation, communications system setting, railway building, greening, river course modification and outdoor supporting project construction.
The Rail Transit No.4 from Cicheng Town to the Dongqian Lake area, with a length of 35.95 kilometers, consists of 25 stations. As is estimated, the whole project will be completed by July 2019, and the trail operation of the lien will be scheduled by the end of 2020.
