Borescope for drilled shaft inspection

This invention describes a specialized camera device designed to look inside deep holes, such as those drilled for building foundations. It features a transparent window for the camera to see through, surrounded by an inflatable ring that can be pressurized with fluid. The device is attached to a telescoping pole, allowing it to be lowered and positioned to inspect the walls of the hole.

Why it matters: Since 2020, advancements in compact, high-resolution imaging sensors and durable, flexible materials for inflatable structures could make the specialized bumper and visual inspection more robust and cost-effective. This could improve the reliability of inspecting challenging borehole environments.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePressurizable bumper, robust housing, camera integration.
