| Abstract: | This paper takes the sewage pipe construction of a sewage treatment plant project in Bangladesh as an example.After replacement of backfills,the bearing capacity and compactness of backfill soil around the pipes of the large diameter pipe are detected by light dynamic penetrator.The relevant laboratory data are compared and studied.The approximate correlation between the blow counts and the bearing capacity and compactness is obtained,so is the threshold value i.e.blow counts in accordance with the design requirements.The application shows that the light dynamic penetration can detect and real-time evaluate the construction quality easily quick.It can guide site construction.The paper has certain reference for similar engineering projects. |
