Project background
 

■ It is located in Ningdong new chemical material Park, Yinchuan City, Ningxia Autonomous Region; the total length of the standard pipe gallery is 13.693km; the pipe gallery is composed of electric tank, comprehensive tank, sewage tank and steam tank.

■ Structural form: closed frame structure is adopted for cast-in-place reinforced concrete structure. Jinhuan Construction Group mainly undertakes the construction of underground comprehensive pipe gallery in the third bid section;

■ Engineering features and difficulties: the construction area is wide, organization and management is difficult; underground and underground obstacles are complex, which has a great impact on the construction of pipe gallery; geological environment is complex and changeable, underground waterproof and anti-corrosion requirements are high quality; deep foundation pit engineering has a long front line, large volume, complex and variable foundation pit support structure, and monitoring and detection is difficult; mechanical and electrical installation engineering has a large volume, many specialties, and traffic Cross operation is frequent; the goal of engineering excellence is high;

■ Technical features: Construction Technology of horseshoe shaped steel wall corrugated pipe gallery; combination of pipe gallery construction and BIM application; application of aluminum alloy formwork in comprehensive pipe gallery.
