Urgent Storm Pipe Rehabilitation as a Result of Lingering Affects and Damage Caused By Hurricane Harvey

摘要

The $150 billion in damage caused by Hurricane Harvey may go down as the most expensive in history. Houston, Texas, endured over five days of high winds, heavy rain and historic flooding. However, the residual effects of its wrath are still being discovered. A three-pipe culvert system beneath a stretch of Clay Road, a highly traveled, multi-lane road serving the city’s commuters and residents, had begun to fail. While it survived the hurricane, the true extent of the multi-pipe storm drainage system’s damage was not discovered until the City conducted post storm inspections. These inspections revealed that large sections of the pipe’s inverts were corroded, and in many cases, completely gone. There was also extreme degradation of multiple wall surfaces and wide pipe joint separations.To give you an idea of how bad the pipe conditions were, sections of pipe were missing to the point that while standing in one pipe, you could see into the adjacent pipe. As a result, the road above was in danger of collapse.The rehabilitation process employed a multi-prong approach to address the gaps, voids and missing sections prior to the structural geopolymer liner being applied. Multiple repair techniques and products were used to structurally rehabilitate the entire pipe runs.
