There is no water leakage or slurry leakage.
The material of the specification steel strip is a .~.thick steel strip. The formed corrugated pipe (detection pipe) requires a thickness of . Generally used in most construction sites, the thickness is about . The specifications of corrugated pipes can be calculated according to the inner diameter or the outer diameter. Most people in the industry calculate according to the inner diameter. The specifications of the inner diameter are, (a factor of ten). Of course, there are also bellows. As for the above
Industry standards and relevant national regulations comply with the national standard, "Metal Corrugated Pipes for Prestressed Concrete Bridges".
Application fields: highway bridges, railway bridges, construction water conservancy, electric power and other national key projects
Prestressed metal corrugated pipes are made of steel strips.
During the winding process, they are simultaneously pressed Connect and press out convex and concave corrugations,
Our company's products have good versatility, Shandong highway bridge standard corrugated pipe + Jinan Xinqiao prestressed metal corrugated pipe price
Good interchangeability, reasonable matching, and easy to use Characteristics such as
(1) Prestressed metal corrugated pipe features: light weight, high stiffness, good tightness, and strong adhesion and pull-out resistance.
(2) Scope of application of prestressed metal bellows Prestressed metal bellows for post-tensioned prestressed reinforced concrete bridges Prestressed metal bellows for reinforced concrete hollow slabs Metal bellows for reserved holes for anchor bolts Construction, construction of walls, foundation pipelines and embedded pipes.
(3) Performance of prestressed metal corrugated pipe products. Rigidity test against concentrated load or uniform load, radial deformation.
. In the anti-permeability test, the cement slurry with a water-cement ratio of . will not leak water or slurry in minutes.
. The tensile test showed no damage to the pipe wall under axial tension.
. Pull-out resistance test Shandong highway bridge standard bellows + Jinan Xinqiao prestressed metal bellows price
The pull-out resistance embedded in concrete is more than . times the designed pull-out resistance of the anchor bolts.
. In the bending test, when the bending degree is the radius of curvature, there will be no water or slurry leakage. Prestressed metal corrugated pipes have the characteristics of impermeability, pressure resistance, high strength and good flexibility, which can ensure construction quality and shorten the construction period. They are widely used in various large and medium-sized bridges, high-rise and long-span construction, dams, nuclear power plants and other projects. .
