1. Rigidity test: When the concentrated load is 0.75KN or the uniformly distributed load is 1.5KN, the radial deformation is Less than or equal to 0.1d.
2. Impermeability test: Cement slurry with a water cement ratio of 0.5 should not leak or leak for 30 minutes.

3. Tensile test: The pipe wall is undamaged with an axial tensile force of 5KN.

4. Pull-out test: The designed pull-out resistance of the anchor bolt embedded in concrete is more than 2.3 times that of the anchor bolt.

5. Bending test: When the curvature radius is 30 days, there is no water or slurry leakage.
