Changchun Rail Transit Line 2 East Extension Project, the right line of the Sanxiang District has successfully started

On September 19, accompanied by the sword of the shield machine slowly rotating, China Construction Co., Ltd. Changchun Rail Transit Line 2 East Extension Project Second Workers Zone Sandao Village East Railway Station ~ San Dao Village West Railway Right It has become the first third shield machine in the board to explore the progress of the third shield machine, marking the new stage of the project's successful into the shield construction.

The strata of this interval are diverse, mainly for the powder and other geology of powder clay layer, full weathering fragrance layer, strong windsonic fragrance layer, and medium mini -wind granite layer. In addition, the interval pipeline is dense, and the number of risk sources along the line is large. When crossing, you need to face the main risk sources such as mitigating iron transmission and distribution of water pipes, concrete transmission pipes, and high -voltage natural gas pipes.

The technical intercourse, strict process control, strengthen construction monitoring, always insist on putting the safety and quality of shield construction in the first place, fully ensure that the shield tunnel is safely traversed, laying a solid foundation for the smooth penetration.

In the next step, China Construction Co., Ltd. Changchun Metro Engineering will continue to adhere to the spirit of the craftsmanship of excellence, pay close attention to important nodes, ensure the construction progress, strictly control the safety quality of the safety quality, and put it in construction production with a fuller enthusiasm and more powerful fighting spirit.
