Large diameter galvanized corrugated metal tunnel

Model Number: CSPE380*140 Brand Name: Qijia Key Specifications/Special Features: Assembly type corrugated metal tunnel are assembled by arc corrugated plates, they arewidely used in culverts, galleries, bridges, tunnels, temporary detours, drain pipes of highway and railway and mine retaining walls of roadway supportingProduct characteristics:1. Ability to adjust foundation deformation, low request of foundation capability and flatness, cost of engineering practice is equal or less than other culverts2. Most obvious advantage is short construction time, building project and socket installation can be carried out separately, then conduct whole assembly3. Centralized manufacturing, productive process is not affected by environment, avail to lowering cost, controlling quality4. Easy installation, does not need large equipment5. Solution to culvert damage from frost6. Reduce or abandon normal construction materials, like concrete, yellow sand, cobblestone, and woods, which means lot to environments7. Rational load to structure, load force distribution, anti-deformation8. Standardized design, simple design and manufacture, short production period9. Improve structure of soft soil foundation and interlocking of junction of embankment, which improves safeness of car on bridgeMaintenance cost of corrugated metal pipes is very low and cost of engineering practice is also lower than other bridge culverts
