How easy is the Suzhou rail transit S1 line test "shield one-key turnover" technology!

Suzhou Rail Transit Line S1 is a subway line under construction in Suzhou. It is 41.27 kilometers long, with 28 stations along the route and a speed of 100 kilometers per hour. The line starts from Weiting Station in Suzhou Industrial Park and ends at Huaqiao Station in Kunshan City, connecting with Shanghai Rail Transit Line 11.

At the beginning of this year, at the construction site of Honghu Station of Line S1, a Sany SCC3500A-6 trackcraneWaiting at the site for the shield machine to come out of the well.

Kong Lingtao, the person in charge of the construction of the project, introduced: "The maximum weight of a single shield to be lifted by this crawler crane is about 120 tons, the lifting depth is 20 meters, and the lifting distance is 10 meters. ”

"The biggest reason for using this model for shield hoisting is that it has a one-key turning over technology for shields, and it can place the shield machine flat on the ground without the need for auxiliary crane cooperation. One car completes the work of the usual two cars, which not only reduces the cost but also saves time for our project team, which is a double thing. ”

Master Li, the operator of the SCC3500A-6, said: "The exit of this shield machine is not large, and it is also an important test for the stability and rotation of the vehicle to let it come out safely and complete the turnover." It has done a good job of this task, and it can be said that it is expected by all. ”

From the start of construction of Suzhou Rail Transit Line S1 to the present, every construction change has plucked everyone's heart. Previously, officials said that the line will start trial operation at the end of 2023. However, according to Cai Rong, secretary of the Party branch and general manager of Suzhou Rail Transit City Line 1 Co., Ltd., at the current rate, it may be put into trial operation half a year ahead of schedule.
