Monitoring Project for Retaining Walls at the Guilin GT Factory Dormitory and Nearby Residential Areas
Project Background
The retaining wall is constructed of rubble-masonry concrete; however, since it cannot adequately support the heavy concrete guardrail, the latter has now been replaced with a stainless-steel guardrail to reduce the load on the wall. Currently, localized deformation and settlement have developed in the backfilled slope, causing the entire mass to slide southward. This has resulted in cracking of the pavement in the residential area of the GT Factory on the north side, as well as structural changes to the retaining wall: cracks have appeared, with the left side of the wall exhibiting a 1-meter-long crack up to 7 cm wide and the right side a 2-meter-long crack up to 10 cm wide. These conditions pose a serious threat to traffic safety on the road below and present significant safety hazards.
The area directly above the retaining wall is only 10 meters away in a straight line. This section has now been paved with asphalt, allowing vehicular traffic and parking, as well as pedestrian passage. The retaining wall as a whole is at risk of downward settlement, posing a serious threat to the structural integrity of the residential buildings in the GT Factory dormitory complex.
Monitoring equipment
By installing intelligent data-collection and early-warning devices—namely, integrated tilt monitors and integrated crack monitors—the structural integrity of the residential community’s retaining walls is subjected to comprehensive, real-time monitoring. Leveraging cloud computing, 4G connectivity, and other advanced technologies, the system integrates wireless sensor data, networked data, and IoT data to establish a localized, three-dimensional, automated monitoring framework that enables round-the-clock, all-space, blind-spot-free automated monitoring and management. Utilizing IoT transmission and wireless sensing technologies, the system seamlessly integrates data acquisition, processing, storage, and transmission via wireless links, and, when combined with a geological-disaster-monitoring system, delivers functions such as data reception, processing, analysis, real-time monitoring, early warning and forecasting, and parameter configuration.
