Prestressed metal bellows
1. Rigidity test: When the concentrated load is 0.75KN or the uniform load is 1.5KN, the radial deformation is less than 0.1d.
2, anti-seepage test: grouting or water-cement ratio of 0.5 cement slurry 30 minutes without water leakage, leakage.
3, tensile test: axial tension 5KN pipe wall without damage.
4. Pull-out test: embedded in concrete, the pull-out force is more than 2.3 times that of the anchor bolt design.
5, bending test: when the bending degree is 30d of the radius of curvature, there is no water leakage and leakage.
