The appearance quality, structural dimensions, ring stiffness, local lateral load flexibility and other technical indicators of prestressed metal products for tensioned prestressed reinforced concrete bridges are in line with/national standards/traffic industry standards. Our products have passed the formal inspection and testing by national authoritative institutions. .
The metal corrugated pipes used in prestressed concrete bridges are impermeable, have high compressive strength and good flexibility, and can ensure construction quality. It has the characteristics of shortening the construction period and is widely used in various large and medium-sized bridges, high-rise buildings, long-span buildings, dams, nuclear power plants and other projects.
Prestressed metal corrugated pipe product performance
Rigidity test resistance to concentrated load, uniform load, radial deformation.
In the anti-permeability test, there will be no water leakage or slurry leakage after the cement slurry is filled with water or the water-cement ratio is 10 minutes.
The tensile test showed no damage to the pipe wall under axial tension.
The pull-out resistance test is embedded in concrete. The pull-out resistance is the designed pull-out strength of the anchor bolts.
The bending resistance test is when the bending degree is the radius of curvature. Pulp.
