Prestressed corrugated pipes are mainly divided into metal corrugated pipes and plastic corrugated pipes. Metal corrugated pipes are mainly composed of two materials, one is black steel strip and the other is galvanized steel strip.
The processing technology mainly uses the machine processing of corrugated pipes. The wavy ports are interlocked with each other and made in circles.
Product performance of prestressed corrugated pipe
Rigidity test: resistance to concentrated load, uniform load, and 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 embedded in concrete has a pull-out resistance of more than the designed pull-out strength of the anchor bolts.
In the bending test, when the bending degree is the radius of curvature, there is no water leakage or slurry leakage.
The material of the specification steel belt is steel belt. The thickness of the formed corrugated pipe (detection pipe) is generally used in most construction sites. The specifications of the corrugated pipe can be calculated according to the inner diameter, which is not different. It can be calculated according to the outer diameter, and most people in the industry calculate it according to the inner diameter. The specifications of the inner diameter include, (a factor of ten, of course, and bellows. As for the above, many places do not provide it (not discussed yet).
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 and electricity and other national key projects
