On May 3rd, Changsha Railway No.1 project of the first phase of the civil engineering project was built on the No. 2 shielded road between the Times Sunshine Road Station and the Xiangfu Road Station. The middle iron Tieshan River was formally launched. Only three months have passed since the start of the tunneling process. Shanhe Intelligence pays close attention to the progress of the project and protects the overall construction of the project.
The Tieshanhe No. 2 shield and the Tieshanhe No. 1 shield on the right, which had just been drilled for excavation, were both earth pressure balance shield machines and were specifically designed for weathering in the operation area of ​​the Changsha Times Sunshine Avenue Station and Xiangfu Road Station. Designed for the stratigraphic characteristics of strongly weathered argillaceous siltstones. The diameter of the cutterhead is 6.28m, the power of the whole machine is 1654KW, the propulsion system adopts 32 propulsion cylinders, the maximum thrust is 3500T, the main drive adopts 8 hydraulic motors, and the maximum torque is 6000KNm. With the addition of the Tieshan Shanhe No. 2 shield machine, the first phase of the Changsha Metro Line 5 formed the simultaneous operation of two shield machines. This will greatly accelerate the speed of tunnel excavation in this area and it also marks the Changsha Metro 5 The main construction work of the first phase of the No. 1 line has entered a new phase.

In order to ensure the smooth progress of Changsha subway construction projects, Shanhe intelligent high-level officials paid close attention to the production and after-sales service of shields. They conducted several on-site investigations and presided over the work conference to supervise the coordination of various departments to do a good job of equipment maintenance and safety emergency response work. The head of the China Railway Five Bureau Project Department said in an interview that “Since China Railway No. 1 was put into use, it has been operating well, has a low failure rate, and has high construction efficiency. In particular, it needs to go through the Guitang River during construction, and it is dangerous. Shield The construction machine functioned smoothly and equipment quality was also a very important factor.China Railway Sanhe also provided us with professional after-sales service engineers to provide 24-hour technical support. With such a professional and efficient team cooperation, we believe we are away from Changsha Metro Line 5 The travel dream has gone a long way." (This article comes from Shanhe Intelligence)
