Inspection of flexible pipe installation occurs when three feet of soil is placed to make sure the pipe is less than five percent deflected. This research aims to define how much more deflection occurs after additional overburden stress is applied. With this the Florida Department of Transportation (FDOT) will be able to identify pipes that are within allowable deflections at time of inspection but may exceed maximum deformations after they are finished being buried. The pipes that were targeted in this project were 36 inch High Density Polyethylene (HDPE), Polyvinyl Chloride (PVC) and steel. They were tested using the Soil Box at the University of Florida. The ten feet wide, 20 feet long, and eight feet tall chamber allows simulated depths of up to 40 feet. Portholes in the side of the box allow deflection readings to be taken as the load is applied. As expected the steel being the most rigid deflected the least amount. The PVC showed even more movement. The most backfill sensitive pipe, HDPE, had greater deformations than all the pipes and when subjected to a trench box installation was the maximum. Overall, the results obtained during this research have proven to show a good trend towards flexible pipe characteristics. This project will continue on to test 24 inch HDPE and steel pipes. Pending these results and comparisons with finite element analysis (FEA) modeling conclusions can be made to better aid the FDOT in on site flexible pipe inspection. ( en )
