Supplying, Installing of Environmental & Geotechnical Instrumentation for Hydropower Dam and Reservoir

Supplying, installing of environmental & geotechnical instrumentation for hydropower dam and reservoir is one of the key services of Vietnam Environmental & Geotechnical Instrumentation Joint Stock Company (VEGI.,JSC).

Hydropower dam is a type of large-scale and complex project with many potential factors causing unsafety to the dam, affecting the operation, environment and population downstream if an incident occurs. Therefore, the installation of geotechnical & environmental monitoring instrumentation for hydropower dam project is always focused and invested to ensure safe, continuous operation as well as being licensed for operation.

VEGI has a team of engineers and technical advisers who have many years of experience in the installation of monitoring systems at hydropower dam projects in Vietnam and neighboring countries in the region such as Laos, Myanmar, Cambodia, etc. Therefore we can meet all the requirements of installing monitoring systems, from manual to automatic system, can transmit monitoring data to Cloud Server VPS with reasonable cost. In addition, we are always ready to support customers anytime, anywhere in the operation, maintenance, repair, etc. monitoring systems.

Our company specializes in the supply and installation of geotechnical and environmental instrumentation such as Inclinometer, Piezometer, Strain Gauge, Extensometer, Datalogger, Rain Gauge, Automated Weather Station, etc. Our company is also a regular and reliable partner of the world’s leading manufacturers of geotechnical & environmental instrumentation such as: Geokon – USA, Campbell Scientific – USA, Texas Electronics – USA, R.M. Young – USA, HyQuest Solutions – Australia, RST – Canada, Roctest – Canada, Sisgeo – Italy, Soil Instruments – UK, ACE Instrument – Korea, Encardio Rite – India, Vaisala – Finland,… We import instruments directly from manufacturers and without intermediaries, ensuring customers get the most competitive prices and incentives.

I. WHY DAM MONITORING?

The most common causes of failure of operating dams are:

• Poor construction materials
• Geological instability
• Landslide into reservoir
• Poor maintenance
• Human, computer or design error
• Internal erosion (earth fill dam)
• Earthquakes

II. SUPPLYING, INSTALLING OF GEOTECHNICAL & ENVIRONMENTAL INSTRUMENTATION FOR ARCH AND GRAVITY HYDROPOWER DAM 

Vietnam Environmental & Geotechnical Instrumentation Joint Stock Company specializes in supplying & installing the following Geotechnical & Environmental instruments for arch and gravity dam projects:

1. Hydropower Dam Instrumentation:  Direct-Inverted Pendulums to monitor horizontal movements in dams, dam foundations

Please see the product details here.

2. Hydropower Dam Instrumentation: VW Concrete Embedment & Arc Weldable Strain Gauges 

Please see the product details here.

3. Hydropower Dam Instrumentation: Concrete Temperature Sensors

The temperature sensor is specially designed for measurement of internal temperature in concrete structures.

Please see the product details here.

4. Hydropower Dam Instrumentation: V-Notch and Flow Meters

Water flow monitoring in open channels is widely employed in environmental and geotechnical field. Leakage measurement is one of the most important indicator of the overall performance of earth/rock-fill and concrete dam.

The leakage rate is a function of the water level in the reservoir and depends either of the construction and of the behaviour of the dam.

Please see the product details here.

5. Hydropower Dam Instrumentation: Tiltmeter

Tiltmeter to monitor tilting and rotation on critical point or on a short base length.

Please see the product details here.

6. Hydropower Dam Instrumentation: Crackmeter to measure movement across surface cracks and joints.

Please see the product details here.
