    Bazhong Reservoir in Sichuang Province, as one of China 172 national major water conservancy projects in water saving and water supply, has transferred from the construction stage to the operation stage from 21 June to 22 June, 2022. The reservoir comprehensively strengthens flood control and has become the first major water conservancy project in the upper reaches of the Qujiang River. It plays important roles on irrigation, flood control and water supply. The total estimated investment of the project is 3.189 billion RMB.                             Slope Monitoring in Reservoir During the construction of water conservancy projects, to ensure the safety and stability of buildings, it is necessary to excavate the mountains, which will form artificial slopes. After the slope is excavated, there will...

      Background of project Hydraulic structures of port wharf, especially gravity-type wharves (or wharves with gravity-type shore connection structures), usually have displacement and settlement during construction and operation, which will adversely affect the safety and normal use of wharf projects. Therefore, it is very necessary to monitor the deformation and settlement of wharf. Finding problems through monitoring and providing deformation data of the wharf in time are necessary measure to ensure the safety of planning, design, construction, and operation of water transport projects, also ensure the safe navigation of ships.   Figure: wharf of Qingdao port The reconstruction project of automatic settlement monitoring in Qingdao port wharf includes settlement, displacement, inclination and cracks monitoring of multiple subjects. In view of the settlement monitoring p...

    From 6th to 10th June, it had a continuous heavy rainfall in some areas of Guangdong Province. On 19th June 19, Shaoguan’s government upgraded the Early Warning Level of Wujiang District and Zhenjiang district from yellow to orange. At the same day, a highway maintainer found cracks in the slow lane of one highway during the patrol inspection, and immediately reported to the superior. On 20th June, it had a big settlement of that highway due to the collapse of the embankment retaining wall. The Highway Administration Bureau quickly coordinated with the relative departments and parties, to make geological survey of the subsidence parts. And then they made and implemented the emergency rescue measures against time. Over the past 7 days, more than 200 rescue personnel, more than 50 mechanical equipment and 450 transport vehicles have participated in the rescue. A...

    Here we share a comparision testing for data comparison between Array Flexible Inclinometer and Manual Inclinometer.Location: in a monitoring project of foundation pit in Shenzhen University, Guangdong, China 1. Introduction of Comparison Testing Project 1.1 Introduction of ProjectDeep foundation pit engineering is common in high-rise buildings and subway construction. Due to the complexity of engineering technology, the internal force and displacement of supporting structure and the internal and external deformation of foundation pit soil are often caused in the process of foundation pit excavation. If the deformation is not controlled properly, it will cause great potential safety hazards to the structural safety of foundation pit itself and surrounding structures. Deformation maintenance structure deep horizontal displacement monitoring, commonly known as inclines...

    Here we share a project of applying AFIC array flexible inclinometer.This project is in a slope beside the highway in Guangdong Province. The hole‘s depth is 44m, and the rock layer is below 20m, soil layer is above 20m. AFIC flexible inclinometer was installed in 20th April, 2022. Its displacement value was stable at 300mm. From 3th June, it started to rain heavily, it keeps raining every day and never stop. The soil layer started to move. In recent 4 days, it moved 10cm every day. In order to ensure the accuracy of the data, the relevant departments used 3 manual inclinometers to measure the nearby holes. Unfortunately, due to the large deformation in recent days, probes got stuck inside the inclinometer tube. From the deformation graphic, you can see now the soil layer already moves 1000mm. Under the huge shear force, Manual inclinometer is no longer avai...

    1. Overview As the basis and premise of engineering construction, earthwork calculation plays an important role in railway, highway, hydropower engineering, port, urban planning and other engineering construction. Accurate calculation of yard volume is of great significance in resource allocation, estimation of project cost, accelerating project progress and improving project quality. In traditional, earthwork calculation is mainly performed by using single point measurement through total station, GNSS-RTK, etc., which not only consumes time and money, but also there is a large error between calculation results and the reality. With the promotion and popularization of 3D laser scanning technology, there is a trend showing the rapid and diversified development for acquisition of 3D point cloud data, which has the characteristics to get quickly and effectively the point ...

    Songpan County, Tibetan Qiang Autonomous Prefecture of Ngawa, Sichuan Province, is located in the western high mountain valley area, with high mountains and steep slopes, steep terrain and complex strata. It is a geological disaster prone and high-risk area. Songpan County has conducted a comprehensive investigation of the whole county and found 469 potential geological hazard points, posing a serious potential threat to the lives and property of nearly 20,000 people in 25 towns of the county.   In order to further standardize the automatic real-time monitoring of geological hazard in Songpan, and continuously improve the scientific and technological level of group monitoring and prevention, the automatic real-time monitoring system of geological hazard in Songpan County was launched, which started  the work of geological hazard monitoring and early-warning in S...

    Project information: This project is located in Singapore, it's used to monitoring landslide. The hole is 63 meter depth. This monitoring site is near an important building, so it's necessary to use real time monitoring solution.    Equipment supply: Finally they asked as supplying 63 meter AFIC chain. Thanks to the 'segments spliced' function, they ordered the chain as 63=20+20+10+10+2+1, in future they can use it in other projects with different depth.    Data analysis: This chain was installed in 7th April,2022, till now it already monitor one month.  The deformation is very clear, the maximum displacement reach 27mm.     ASSOCIATED PRODUCTS                                         Flexible Inclinometer    &...

    In 2021, berths of Beihai Port, China began the rubble base construction. It is proposed to build 2 general berths of 100000 tons and 3 general berths of 5000 tons for the wharf hydraulic engineering of the project. The project department shall carry out safety technical disclosure in strict accordance with the construction scheme, reasonably arrange ship machinery equipment, and adopt GPS automatic positioning system to accurately position the riprap ship to ensure the smooth progress of the project.   Figure: Beihai Port     Settlement Monitoring of Foundation Bed As the construction of the project continues, the settlement monitoring of foundation bed during berths construction has become more and more important. The settlement of foundation bed refers to the settlement of foundation surface caused by the compaction of foundation soil layer under the a...
