Sinkhole Early Detection System

A pilot study was performed to determine the viability of a permanently installed sinkhole detection device for use in both commercial and residential applications. The current state of the practice methods for sinkhole detection provide only a single snapshot in time of subsurface conditions. The theory investigated was the concept that if a sinkhole is forming underneath an existing structure, the void forming could be detected mechanically by a falling weight causing a trigger to alert occupants. The device would be installed through the existing floor and at a depth such that the sinkhole void could be detected prior to any damage to the structure. Prototypes were constructed and tested in various environmental conditions for durability and in simulated sinkhole conditions in the field. While impediments to widespread use exist, the device appears capable of serving as a sinkhole early detection system.
