5473 meters in length!Shenbai High -speed Railway Shuangshan Tunnel Candidum is officially started

After full analysis and judgment and careful preparations, the Shenbai High -speed Railway Shuangshan Tunnel inclined wells undertaken by the China Railway 15th Bureau Group was officially started, marking the stage of entering the tunnel construction stage.

The Shenbai High -speed Railway Shuangshan Tunnel with a total length of 5473.25 meters is located in Da'an Town, Tonghua County, Tonghua City, our province. It is a single hole and double -line tunnel. The geological conditions of the tunnel areas are complicated, the mountains are steep, and the local paragraphs have a phenomenon of rich water. It is easy to occur in geological disasters such as collapse and pouring mud. The construction safety risk is high and the construction is difficult. In addition, the tunnel is in high -latitude cold areas, with a short effective construction period and listed as controlled projects across the line.

The two -mountain tunnel diagonal well, which is starting with a total length of 286 meters, is located on the right side of the line. It is based on the full analysis and judgment of the geological situation of the positive cave. The two -way excavation construction is carried out through it into the positive cave. The purpose is to reduce the construction risk of the growing tunnel and further alleviate the pressure of construction work.

"We plan in advance, actively coordinate, and strive to overcome the adverse effects of time, heavy tasks, etc., and quickly complete the preparations of the ground clearance and resources to enter the field to ensure the smooth construction of the oblique well." Wang Xiaorong, the person in charge of the project, said, " The official construction of the oblique well means that the construction of the tunnel project has made a new breakthrough, providing favorable conditions for subsequent construction and accelerating construction progress.
