Title:
METHOD FOR DETECTING DAMAGE TO A DECK OF A BRIDGE
Document Type and Number:
WIPO Patent Application WO/2010/131489
Kind Code:
A1
Abstract:
Provided is a method for detecting damage to a deck of a bridge, said method allowing detection work to be performed with a low amount of labor and being capable of reducing the time and cost needed for the detection work. A road-surface measurement vehicle, which drives on pavement (3) on top of a steel-plate deck (1), uses a thermal infrared imaging camera to acquire thermal infrared video of the surface of the pavement (3). On the basis of the thermal infrared video, troughs (4) of the steel-plate deck (1) are detected, giving a picture of the structure of the steel-plate deck (1). Accumulated water inside prescribed trough members (41) and sealing diaphragms (42) is detected from low-temperature regions (R2) from among regions corresponding to troughs (4) in the thermal infrared video, and from rectangular low-temperature sections (L2) that surround said regions (R2). Penetrating cracks are detected in deck plates (2) that correspond to troughs (4) in which accumulated water has been detected.
