During the construction of a high-speed rail project, the presence of adverse geological conditions, specifically landslides, posed significant risks to safety and stability. Despite implementing reinforcement measures such as pile walls and anchored piles, the threat of deformation and instability remained, particularly due to construction disturbances and rainfall. To mitigate these risks and ensure safe construction practices, Geositter (developer of Inclino-Robot) devised an innovative automated monitoring solution leveraging Internet of Things (IoT) technology.
The mountainous terrain and unpredictable weather patterns create a challenging environment for construction projects. The high-speed rail line, designed to enhance transportation efficiency in the region, faced the dual challenge of ensuring structural integrity while safeguarding worker safety. The geological assessment revealed the potential for landslides, particularly in sections where heavy machinery and excavation activities were prevalent. Recognizing the urgency of the situation, our team developed a comprehensive monitoring strategy to proactively identify and address any signs of instability.
The monitoring strategy included a meticulous arrangement of measurement points to ensure all aspects of landslide risk were covered:
Surface Displacement Monitoring: GeoSitter established several displacement monitoring points along the main axis of the landslide. Based on the width and characteristics of the landslide, at least two monitoring points were strategically placed to capture real-time deformation data effectively. GeoSitter deployed five GNSS (Surface Displacement Monitor) devices across the landslide area, allowing for comprehensive and high-precision surface displacement monitoring.
Vertical Displacement Monitoring: Deformation Monitoring: Three automated in-place inclinometers- (Inclino-Robot) were installed to assess deep-seated deformations beneath the surface, providing insights into potential underground shifts. These systems were strategically located in high-risk areas to monitor subsurface stability, enabling early detection of movement. Each inclinometer is equipped with high-precision sensors that continuously transmit data for real-time analysis, ensuring timely responses to any detected changes and enhancing overall project safety.
Groundwater Monitoring: Each monitoring section was equipped with at least one groundwater monitoring point to track fluctuations in groundwater levels, which directly influence landslide stability. A dedicated Water Level Meter was implemented to monitor underground water levels in real-time, facilitating ongoing analysis of their impact on landslide stability.
Rainfall Gauges: Rain Gauges were installed at every accumulation site to provide crucial data on precipitation levels, aiding in the assessment of potential landslide triggers. Four rain gauges were utilized to continuously measure rainfall intensity and volume, establishing a direct link between weather patterns and landslide potential.
High-Precision Sensors: GeoSitter geotechnical monitoring instruments was equipped with high-precision sensors capable of triggering alerts when displacement reached predefined thresholds. This immediate response feature was crucial for maintaining safety during operations.
Comprehensive Data Transmission: The monitoring system supported multiple data transmission methods, including 4G, Lora radio, RS232, and RS485. This flexibility allowed the integration of various general-purpose sensors, ensuring extensive coverage even in complex environments.
Multi-Station Data Integration: By utilizing data from multiple monitoring stations, we achieved minute-level high-precision positioning, providing a reliable basis for assessing landslide displacements and ensuring the accuracy of our monitoring data.
Multi-Parameter Analysis: Our GeoSitter Monitoring Data Platform integrated diverse parameters, including displacement, rainfall, and groundwater levels, allowing for a holistic assessment of slope stability and safety conditions.
GeoSitter Monitoring Data Platform developed by engineering experts, offers intelligent data management, customizable features, and compatibility with various instruments, ensuring efficient monitoring and reliable analysis for diverse engineering projects.
GeoSitter offers comprehensive support including remote troubleshooting, on-site maintenance, and regular system updates to ensure the monitoring system operates smoothly and efficiently.
Remote Troubleshooting: Our team offers remote support and training service to equip the clients with the skills necessary to navigate the monitoring platform effectively and ensure that all monitoring devices were installed and calibrated correctly, enabling optimal performance throughout the monitoring period.
Regular System Updates: We provide periodic data platform updates to enhance its functionality, introduce new features, and address any security concerns. These updates ensure that clients benefit from the latest advancements in monitoring technology, optimizing their operational efficiency.
On-site Maintenance: At the request of the clients, our experts visit construction sites to perform on-site maintenance and support. This includes troubleshooting any issues with monitoring devices, ensuring proper calibration, and providing hands-on training to staff, which helps maintain system integrity and performance.
The implementation of this automated monitoring solution has significantly enhanced the safety and stability of the high-speed rail project. By utilizing cutting-edge technology and a proactive approach to monitoring, we have established a robust framework that safeguards against the risks posed by adverse geological conditions. This initiative exemplifies our commitment to ensuring the successful completion of infrastructure projects while prioritizing safety and environmental considerations. Together, we can support the smooth progression of high-speed rail construction and contribute to the region's development.
