Civil Engineering Measuring Systems

This Measuring System measures the deformation and displacement of a dam by applying a plumb line. The normal plumb line measures deflection from the relative displacement between the crest and bottom of the dam, and the reverse plumb line measures horizontal displacement from the relative displacement between the bottom of the dam and the immobile bedrock. Real-time measurement and output in the measurement range (0 to 100 mm) in two directions (X and Y) are possible.

The dam body behavior observation system is suitable for management of various dams.

The landslide observation/monitoring system enables system configuration matched to each individual environment and measuring purpose.

Understanding the seismic behavior of dams, which are very large civil engineering structures, is important information for the structural design of dams. The seismic analysis results obtained from the completed dam are compared with the design calculations and reflected in the subsequent dam design. Seismic observation points are used to record seismic vibration waveforms for the three components (X, Y, and Z) of the vibration at the top of the dam embankment, bottom (foundation), and ground level for the necessary time.

The bedrock data acquisition system provides a large-capacity storage to enable a continuous 24 hours of measurement.

Dynamically Measure the Behavior of Offshore Structures This is a measurement system for field demonstration tests of caissons constructed offshore. There are three types of measurement systems. ・Unmanned ocean observation and recording system ・Submarine multi-core cable system ・Optical fiber and power composit submarine cable system

This is a measurement system for measuring the seismic behavior of various structures such as offshore structures. The output from detectors installed on the structures and the surrounding ground is sent to the observatory.

This system is designed to maintain a safe final disposal site by constantly monitoring leachate generated in the site for leaks.
