On July 28, 2026, a range of domestically developed communication signal smart construction equipment, created by China Railway Construction Electrification Bureau Group, was first deployed on the Anyue to Dazu section of the Chengdu-Chongqing Central Line high-speed railway.

This marks the official entry of the line's weak-current engineering into a new phase of mechanized and digital intelligent construction.

On July 28, 2026, on the Anyue to Dazu section of the railway, staff from China Railway Construction Electrification Bureau Group were seen using smart equipment for cable laying and drilling operations.

The Chengdu-Chongqing Central Line high-speed railway is a key project within the national "Eight Vertical and Eight Horizontal" high-speed rail network's Yangtze River corridor. With a main line length of 292 kilometers, it will reduce travel time between Chengdu and Chongqing to 50 minutes once completed.

The line is designed to accommodate higher future operating speeds, setting stringent standards for the precision and safety of its communication signal system.

The equipment deployed this time covers the entire cable laying and drilling construction chain, adopting a green, intelligent model to overcome the challenges of traditional weak-current construction, which relies heavily on manual labor and experience-based operations.

The new energy automatic intelligent cable-laying vehicle features BeiDou positioning, automatic obstacle avoidance, and intelligent cable-laying functions.

The modular intelligent drilling equipment can be adapted to multiple scenarios, including track slabs, rails, and anti-collision walls, significantly improving construction precision and efficiency compared to manual operations, with work efficiency more than doubled.

The large-scale promotion of a complete set of intelligent construction technologies on the Chengdu-Chongqing Central Line high-speed railway represents a shift from "experience-based construction" to "data-driven construction," providing practical reference for major national railway projects.
