Congratulations to Goodeng Machinery GSE12000-L new energy super-large horizontal directional drilling rig for successfully completing the first drilling and back-pulling of the Litong Construction Sichuan-East Gas Transmission Phase II North Trunk Canal directional crossing project φ1016mm×690m!

 The Sichuan-East Gas Transmission Phase II has a total length of 4,269 kilometers, passing through 8 provinces and cities including Sichuan, Chongqing, Hubei, Anhui, and Zhejiang. The entire line is constructed in sections, namely the western section and the eastern section. The eastern section has a total length of 2,698 kilometers, including one main line, two connecting lines, and three branch lines. The pipeline is designed for a pressure of 10 MPa, with an annual designed capacity of 14 billion cubic meters.

This project uses φ1016mm×690m pipes and successfully addressed complex locations such as rock and sand layers, perfectly meeting the construction requirements.
