∷Application：

When the pipe under river is broden,the traditional trenchless rehabiliatation solution may not suitable for this situation because it's not easy to drain out the water inside the host pipe.

Also there will be lots of bends on the host pipe, so the HDPE pipe insertion method may not possible to use either.

Cross-River pipeline rehabilitation procedure:

1. Using a underwater robot to Inspection during full water level.

2. Host pipe cleaning

3. Host pipe reinforcement , reconnect the dislocation pipeline

4. Pipe-in Liner™ insertion

5. Install couplings

6. Test the host pipe

7. Connect the host pipe into the pipeline network
