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 control projects of Sandi Road. It connects Nanling and Fanchang counties, and is connected to National Highway G205, Wuxuan Expressway in the east, Xitong Yanjiang Expressway and Wuhu Yangtze River Wharf. The bridge was opened in March 2011 and closed in October 2012. In 2015, Taibai Avenue was completed and opened to traffic. The Zhanghe New Bridge across the Zhanghe River was praised by the people for its beautiful shape and colorful lights at night. It looks like a rainbow. The folk convention calls it "Rainbow Bridge".
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 simple-supported continuous composite box girder bridges respectively. The total length of the bridge is 431m, and the main bridge is 44m wide. The superstructure of the main bridge is composed of steel arch ribs, prestressed concrete box girder and flexible suspender. The box girder is of single box and six room section, and adopts three-way prestressed system.
The Zhanghe New Bridge is an important bridge project on the Sandi Highway, and the Sandi Highway in Wuhu City is an important county road in the city area, and it is the main road in the nine vertical and eight horizontal roads of the main road network. Therefore, the Zhanghe New Bridge, known as the "Rainbow Bridge", is of great significance for Sandi Road to promote the social and economic development of Wuhu City, accelerate the development process of Wuhu City's urban-rural integration, and truly connect 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.
