Hangzhou-fuyang metro is expected to enter the tunnel excavation stage by the end of 2020

Recently,gaojiao road station and north railway station of automobile (the name of the project site) of hangzhou-fuyang subway station started to use two sets of shield construction, which marked that hangzhou-fuyang subway officially entered the tunnel excavation stage.

This is a 70 meters long mechanical corridor formed by various electrical equipment and power equipment connected together. Under the thrust of the jack, the front end knife with a diameter of 6.48 meters spirals forward to dig the soil layer and cut the soil mass. The automatic conveyor belt connected with the shield body will transport the excavated earthworks to the rail car at the end of the tunnel, and then continuously send them out of the tunnel. The shield tunneling machine operates 24 hours a day and can dig 6 to 8 meters a day.

The reporter noted that, while "eating the soil" went forward, a pipe segment assembly machine on the shield machine automatically installed the pipe segment, six pieces of reinforced concrete pipe segments assembled into a huge pipe, and synchronous grouting, equivalent to the tunnel wall mounted "bell jar".

"When the shield tunneling machine is in operation, the above-ground area will not be isolated for disposal, and pedestrians and vehicles can pass through as usual." According to Chen bin, director of safety and quality of hang-fu subway project, the current shield technology can realize underground operation without affecting the ground traffic. The shield machines used in fuyang are electrically driven and do not require blasting or internal combustion engines. This construction method eliminates both the dust and noise that may be generated during blasting, as well as the noise and exhaust gas generated by the rumbling internal combustion engine, so that the pedestrian on the ground will not feel the underground vibration and will not hear the noise.

We have learned, in July 2017 to start construction HangFu subway project, the 23.5 km line starting point for the academy in xiangshan, silver lake streets, inferior to the west longitude streets, the finish is located in the streets, inferior osmanthus road station (phase I), set up 11, design speed of 100 km/h, broadly into the ground, is expected by the end of 2020 and the metro line 6 is well versed in hangzhou.

Up to now, the construction of the main earthwork of the bus north station, gaojiao road station, fuchun station and guihua road station in fuyang urban section of hangzhou-fuzhou subway has been basically completed, and the construction of the middle plate and roof plate of the main structure of the station as well as the earthwork clearing and transportation are being carried out in an orderly manner. The excavation work has been started for the construction of 4 stations and 1 future reserved station in the 320 section of hangzhou-fu subway.

The west extension project of rainbow express road, which is synchronously promoted with the 320 national highway section of hangzhou-fuzhou subway, has completed the pipeline transformation and the bottom slab pouring work has started.

Shield tunneling work on the fuyang section of the hangzhou-fu subway will be fully opened by June this year, with 16.8 kilometers of underground tunnels dug. According to the schedule of the project, it is expected to complete the main construction by June 2020, and then move to the 6-month subsidiary project construction stage.
