A Perfect Breakthrough for "Henglong" Rectangular Pipe Jacking Machine

  • 2024-07-26

On July 15th, as the cutter head of the large-section rectangular pipe jacking machine "Henglong" broke through the ground, it marked that the large rectangular pipe jacking project under construction in Jinan Rail Transit finally ushered in the moment of victory after more than 40 days and nights of hard work.

 

In the A entrance and exit section of the west station of Xingcun Interchange of the first phase of Jinan Metro Line 4, the pipe jacking covering depth is only 4.7-5.5 meters, and the jacking distance is about 80 meters. Since the crosswalk needs to pass under the busy Jingshi Road, the surrounding pedestrian and vehicle traffic is large, the underground pipelines are dense, the geological conditions are complex, and the construction is difficult.

 

The "Henglong" earth pressure balance rectangular pipe jacking machine is 9.1 meters wide and 5.5 meters high. The machine is equipped with complex geological efficient cutting technology, high-performance power drive and sealing devices, and efficient and reliable spiral excavation system and other advanced technologies, which together weave a safety net to ensure the smooth progress of the project. In addition to the delivery of technically advanced pipe jacking equipment, Tangxing also provides all-round and high-quality service guarantees, from professional operation training to equipment assembly and commissioning. On-site service personnel are on call around the clock, providing strong technical support for the efficient advancement of the project!

 

Jinan Metro Line 4 serves as the "spine" channel connecting Jinan's urban development. After completion, it will effectively alleviate the pressure of east-west traffic congestion in Jinan and play an important role in promoting the coordinated economic development of the city's eastern and western regions.
