en.Wedoany.com Reported - The Tiantangzhai Branch Line Section 02 project, undertaken by Jiangong Lugang Company, is progressing deep in the Dabie Mountains. This 11.195 km expressway, located in the mountainous region of western Anhui, features a bridge ratio of 36.88%. The route traverses multiple fault zones, steep slopes, and karst development areas, posing significant construction challenges, numerous safety risks, and high ecological protection requirements. Since the start of construction, the project team has been deeply rooted in the mountainous frontline, breaking through technical difficulties, improving efficiency through digital and intelligent management, and steadily advancing the project amidst the rugged terrain.
Facing challenges posed by the complex terrain, the technical team innovatively applied hydraulic climbing formwork and intelligent verticality monitoring technology during the construction of the 64.5-meter-high main pier of the Dousha River Bridge, achieving millimeter-level precision in capping. For the 2,233.8 cubic meter super-large pile cap of the Qingshui River Extra-Large Bridge, hundreds of temperature sensing points were integrated and deployed within the concrete. Construction personnel monitored parameters around the clock, setting a record for the largest single continuous pour of a pile cap on the entire line. The first 0# block of the continuous rigid-frame bridge on the line has been completed, officially kicking off the construction of the bridge's superstructure. Currently, the 96.3-meter-high pier column of the Qingshui River Extra-Large Bridge is rapidly rising, while subgrade works are progressing orderly according to milestones, with the critical path consistently leading the schedule. The project is also conducting a labor competition, organizing team competitions around "comparing progress, quality, safety, and civilized construction," establishing a weekly scheduling and monthly evaluation mechanism. Party members and key personnel take the lead, maintaining a vigorous construction momentum on site.
In terms of labor management, the project fully utilizes a labor management system. Relying on the "Legongbao" mini-program and electronic fence technology, it achieves a closed-loop online process for worker real-name registration, facial recognition attendance, and salary confirmation. The system uses dual verification of GPS positioning and facial recognition to lock in actual attendance, with attendance data automatically linked to salary calculation. Salary payments require the worker's own facial recognition confirmation, preventing issues such as false attendance reporting and fraudulent salary claims from the source. The system also features automatic interception of over-age personnel and blacklisted individuals, with one-click verification of personnel qualifications, making personnel management for long-line mountain projects more precise and standardized.
In terms of digital and intelligent management, the smart material system enables automatic weighing of incoming materials and full traceability, strictly implementing a three-level procurement and quota-based material requisition system to precisely control the consumption of main materials such as rebar and cement. Cost control relies on a quantity calculation system that connects the entire data chain of quantity verification, progress collection, and cost control, achieving "one data source, multi-department reuse." The project simultaneously implements a "large team" management model, adopting measures such as permanent-temporary combined access road construction and resource utilization of engineering waste. On-site management introduces an drone intelligent inspection system for routine progress verification, hazard identification, and dust monitoring across the entire line. Additionally, a large-scale engineering personnel safety non-intrusive monitoring system is deployed, dynamically assessing workers' physiological and psychological states through non-contact detection, shifting safety management from "passive inspection" to "active prediction."
In terms of safety production, manual hole-digging piles implement full-process standardized control, with pre-embedded anti-fall anchor points at the collar and standardized enclosures at the pile opening. High-pier construction uses lightweight combined hoop connections for ladder cages, and mud pits are equipped with standardized working platforms. The project designates party member responsibility zones, incorporating high-risk projects such as high piers and deep foundation pits into their scope. Daily safety morning briefings and routine hazard inspections are adhered to, achieving closed-loop management of hazard rectification. Since the start of construction, the project has maintained a zero-accident safety record. After the flood season, facing challenges from heavy rainfall and typhoons, the project strictly implements a 24-hour emergency duty mechanism, conducting thorough inspections of key areas such as high slopes, deep foundation pits, and temporary camps. Sufficient flood control materials are stockpiled, and practical drills are conducted to ensure smooth and orderly construction during the flood season.
Next, the Tiantangzhai Branch Line Section 02 project will continue to deepen smart construction and refined management, focusing on safety production, progress control, and quality improvement to create a quality project, a safe project, and a green project, injecting transportation momentum into the high-quality development of the Dabie Mountain old revolutionary base area.
