Scouring is wearing away of riverbed material that supports piers or abutments. The piles or pier foundation get exposed down to significant depths due to large scale scouring. This may destabilize the foundation of the bridge causing bridge failure. Scouring thus compromises the safety of the bridge. It has been the cause of failure of several bridges around the world. It is thus, critical for the stakeholders to detect the occurrence of stream/riverbed scour at bridge piers and monitor the scour depth variation.
Encardio-rite offers two innovative bridge (streambed) scour monitoring solutions that provide crucial information in near real time on the dynamics of sediment scour and aggregation.
Each system has its own application and is used based on the site requirement. Their rugged design is ideal for safety monitoring of structures such as bridges that are located in high-current or deep-water environment.
Model EBSM-101 datalogger is available to accept input from up to three magnetic probes and/or sonar scour monitoring sensors. The magnetic and sonar monitoring sensors are connected to the datalogger through separate individual serial bus cables. The datalogger has the facility to collect and store recorded data and transfer it to a central remote server at desired intervals over a wired or cellular telemetry link.
A data management software (Drishti) can be installed at a central server to processes and analyses the data. In case any value breaches programmed alert level, the system sends an alarm to the stakeholders via SMS or email.
