| Abstract: | Grouting inside the pipes of the practical pre-stressed members is simulated by constructing concrete slab in laboratory.Grouting condition inside the model pipe is checked by scanning type shock echo method.There are two types of the pipes,i.e.metal corrugate pipe and plastic corrugate pipe.Three options of grouting inside the pipes are simulated,including dense grouting,half empty and full empty. |

| Keywords: | scanning type shock echo method pre-stressed pipe grouting quality model test |
