Date: September 2025
Construction Location: Foshan City, Guangdong Province
Project Name: Foshan Xuda Power Tunnel Project
Project Type: Power Engineering
Equipment Details: Tangxing Technology HRC 2800mm Rock Pipe Jacking Machine
Jacking Distance: 1,148 meters
Geological Conditions: Composite geology of silty clay, rocky strata, and oyster shell attachment layers
Project Challenges: Underpassing municipal roads, waterway channels, park structures, and side-crossing a water overpass bridge, with significant challenges including ultra-long distance, dual-section curves, deep burial, and high-risk factors.
Project Significance: The successful completion of the section between working shafts #7 and #8 is a key milestone in the construction of the Foshan Xuda Power Tunnel project. It not only marks significant progress but also serves as a valuable practical experience in long-distance pipe jacking technology under complex geological conditions. This experience provides crucial technical support for the construction of working shafts #2 to #3, accelerating the overall progress of the project.
