Safety Monitoring System of Rainbow Bridge in Nanling County, Wuhu City, Anhui Province
Zhanghe New Bridge (Rainbow Bridge)
Zhanghe Bridge is located in Wuhu City, Anhui Province, China. It is one of the key projects of Sandi Road. It connects Nanling and Fanchang counties, and is connected to National Highway G205 and Wuhu-Xuancheng Expressway in the east, Yanjiang Expressway in the west, and Wuhu Yangtze River Wharf. The construction of the bridge started in March 2011 and was completed in October 2012. In 2015, Taibai Avenue was completed and opened to traffic. The new Zhanghe Bridge, which spans both sides of the Zhanghe River, has been praised by the people for its beautiful shape and colorful lights at night, and its shape resembles a rainbow. It is commonly called "Rainbow Bridge" by the people.
The main bridge of Zhanghe Bridge is a three-span special-shaped arch continuous box girder bridge, and the west and east approach bridges are four-span and six-span first simple support and then continuous composite box girder bridges respectively. The bridge is 431m long and 44m wide. The superstructure of the main bridge consists of steel arch ribs, prestressed concrete box girders and flexible hangers. The box girder is a single-box six-chamber section with a three-way prestressed system.
The new Zhanghe Bridge is an important bridge project on the Sandi Highway, and the Sandi Highway in Wuhu City is an important county road in the urban area and a major transportation artery among the nine vertical and eight horizontal trunk road networks. Therefore, Zhanghe New Bridge, known as the "Rainbow Bridge", is of great significance to Sandi Road in promoting the social and economic development of Wuhu City, accelerating the process of urban-rural integration in Wuhu City, and truly connecting the three counties.
Static Level
MAS-HLS static level is a high precision, high stability of intelligent static level. The product is made of aluminum alloy, lightweight integrated structure, durable. Equipped with a continuous standard level interface and back pressure interface, the joint with locking function is not only convenient for pipeline connection operation, but also can ensure the sealing of water and gas circuits. A product designed for settlement detection with multiple static level gauging instruments that can be connected by bus and have manual exhaust devices.
Accelerometer
MAS-VBS-A01 accelerometer is a capacitive vibration sensor. It has the characteristics of small size, light weight, good low frequency characteristics, high resolution, large dynamic range, and convenient use. It can be applied to bridge vibration monitoring, cable force monitoring, blasting vibration monitoring and motor vibration monitoring.
Resistance Strain Gauge
The MAS-SMDT-15 resistance strain gauge is suitable for long-term laying on the surface of steel structure or concrete structure to measure the stress and strain on the surface of the structure. The sensor is rugged and easy to install.
The output of the sensor is 3 to 4 times that of the ordinary strain gauge, and the higher signal-to-noise ratio has a higher resolution, which is compatible with various data acquisition systems. The signal is transmitted by a dedicated four-core shielded cable, which reduces the impact of noise on the signal.
Temperature Sensor
The MAS-T temperature sensor adopts international advanced sensitive components, which can be used to monitor the temperature of the environment; it can be used for hydraulic structures, high slopes, roads, bridges, dams, industrial automatic control, tunnels and other safety monitoring projects with harsh environment.
