Construction
| Split Band Couplers: | |||
| Description: The split band couplers are corrugated to match the pipe’s corrugations and engage at least two full corrugations on each pipe end. The split band couplers must be supplied by the same manufacturer as the pipe. | |||
| Installation Instructions: Cut out the damaged area, make cuts in the center of the corrugation valley. Cut the replacement pipe section to the desired length. Trim any polyethylene burrs from saw cut. Excavate bedding from under the existing pipe cut ends. The split band couplers are installed by laying the adjoining sections of pipe in the open split band coupler and wrapping the coupler around the pipe. Nylon ties are fed through the holes in the ends of the coupler and pulled tight. The pipe and inside of the coupler should be free of debris. Carefully replace and compact bedding and backfill to provide proper support for pipe and coupler. | |||
| For cracks, joint defects and minor damage excavate from under the existing pipe to a width greater than the bands. Center the coupler over the damaged area and warp the coupler around the pipe. Nylon ties are fed through the holes in the ends of the coupler and pulled tight. The pipe and inside of the coupler should be free of debris. Carefully replace and compact bedding and backfill to provide proper support for pipe and coupler. | |||
| Repair method should only be considered in perforated systems since it will not meet soil tight/watertight requirements as defined in Florida DOT Standard Specification Section 430. | |||
