How JOUAV Safeguarded China’s “Golden Route” G318 After a Landslide?
In the early hours of December 3, 2025, a landslide tore through Qixing Town in Chongqing, violently displacing roads and buckling the ground beneath a critical section of National Highway G318.
As the essential "Golden Route" for regional logistics and tourism, every hour of closure meant spiraling economic costs and fractured supply chains.
Authorities faced an immediate dilemma: they needed to understand the scope of the disaster instantly, but sending survey crews onto the unstable, crumbling slope was far too dangerous.
Time was critical, but safety was non-negotiable.
The Answer Was in the Air—And in the Network
The solution came not from the ground, but from an integrated low-altitude intelligent network. Leveraging its Liangping cloud-to-edge infrastructure, JOUAV initiated a fully remote and unmanned response.
From a command center miles away, operators activated two automated VTOL Hangar systems stationed in the Liangping High-Tech Zone and Yuanyi Town.
Within hours, JOUAV CW-15V UAVs embarked on autonomous, beyond-visual-line-of-sight (BVLOS) flights, navigating over 20 kilometers through nighttime conditions to arrive at the disaster zone.
Crucially, not a single pilot or engineer was ever required at the hazardous landslide site, eliminating all personnel risk and enabling assessment while the situation was still actively evolving.

Sustained Eyes on the Evolving Crisis
Once on station, the CW-15V vertical take-off and landing fixed-wing UAV began a relentless seven-day monitoring mission. Its unique design provided the endurance for wide-area coverage and the flexibility for precise, persistent observation.

Equipped with a suite of professional payloads—from high-resolution oblique cameras for 3D modeling to real-time electro-optical gimbals for live video—the system constructed a comprehensive, dynamic digital twin of the entire affected area.

This continuous data stream was transformed into actionable intelligence through JOUAV's analytical platform. Experts could detect subtle ground deformation invisible to the eye, calculate precise landslide volume for removal planning, and model risk trends.
This clear, scientific picture empowered a critical decision: to safely restore limited emergency traffic while implementing a protocol for long-term monitoring and mitigation.

From Emergency Assessment to Safeguarding Recovery
The mission’s role extended beyond the initial crisis. In January 2026, the same unmanned system was redeployed to oversee the emergency road diversion construction along G318.
It provided project managers with regular, detailed surveys to track progress and, more importantly, served as a vigilant guardian—continuously verifying slope stability to ensure construction activities did not inadvertently trigger secondary slides, thereby protecting the workers and machinery below.

The JOUAV Difference: Clarity Without Compromise
The Chongqing landslide response underscores a new paradigm in emergency management. By combining automated, remote-operated aircraft with robust network infrastructure and intelligent data analytics, JOUAV delivered something previously difficult to achieve: rapid, decisive clarity without exposing a single person to danger.
The result was a faster, safer, and more informed pathway from crisis to recovery, turning raw data into the confidence needed to make critical decisions and protect what matters most.
