Bunkers Corrugated Sheet Roll Forming Machine For Drainage Channels

• Road and rail: culverts, channels, bridges, tunnels, tunnel culvert repair, temporary pavement, infiltration wells
• Municipal and construction: a common ditch, light cable protection, drainage ditches, crane cofferdam, vertical pile shell
• Coal mine: mineral pipeline, personnel and mining machinery channels, shaft
• Civil: power plant flue gas, grain storage warehouse, fermentation tanks, wind power
• Military: Military service road, air channels, evacuation routes

• Corrugated steel culvert both rigid and flexible; structure of reasonable force, load distribution, a certain resistance to deformation.
• Use of standardized designs, factory-scale production; short production cycle, high efficiency, helps reduce costs and improve quality.
• On-site installation of speed, short construction period, social economic benefit.
• Year-round construction, construction not subject to seasonal effects, not environmental impact.
• Can effectively solve the freezing cold north area of concrete bridges and culverts due to repeated failure problems.
• Especially for long: East soil, expansive soil, soft soil, loess and other special areas, to avoid uneven settlement of foundation deformation caused by the destruction of the culvert.
• Reduce the cement, sand, gravel and other conventional building materials used, environmentally significant.
• Compared with concrete bridges and culverts, the same span corrugated steel culverts and lower total cost.
• Small post maintenance work, maintenance and low cost.
