Guilin Qixing Housing and Urban-Rural Development Bureau Old Residential Area Safety Monitoring Project
Project Background
The retaining wall was constructed using rubble‑stone concrete masonry. As it could not adequately support the heavy concrete guardrails, these have now been replaced with stainless‑steel railings to reduce the load on the wall. Localized deformation has developed in the backfilled slope, accompanied by soil settlement, causing the entire structure to slide southward. This has resulted in cracking of the pavement in the residential area adjacent to the GT Factory to the north, and changes to the wall’s structural integrity: cracks have appeared, with a 1‑meter‑long crack on the left side measuring up to 7 cm wide and a 2‑meter‑long crack on the right side reaching 10 cm at its widest point. These conditions pose a serious threat to traffic safety on the road below and present significant safety hazards.
Just 10 meters in a straight line above the retaining wall, the area has now been paved with asphalt, allowing vehicle traffic and parking, as well as pedestrian passage. The retaining wall as a whole is at risk of downward collapse, posing a serious threat to the structural integrity of the residential buildings in the GT Factory dormitory complex.
Monitoring equipment
By installing intelligent data‑acquisition and early‑warning devices—such as integrated tilt monitors and integrated crack monitors—the system conducts comprehensive, real-time monitoring of the retaining walls and structural integrity of residential buildings. 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, enabling round‑the‑clock, all‑space, blind‑spot‑free automated surveillance and management. Employing IoT transmission and wireless sensing technologies, the system consolidates data acquisition, processing, storage, and transmission into a unified workflow, with data delivered wirelessly. Combined with a geological hazard monitoring system, it supports functions such as data reception, processing, analysis, real-time monitoring, early warning and forecasting, and parameter configuration.
