en.Wedoany.com Reported - Several projects under construction by China First Metallurgical Group have reached key milestones in the third quarter. The mainline pavement of the Luolu Expressway Section 3 project has achieved full cement-stabilized base course completion. The mainline cement-stabilized base course paving covers a single-lane length of over 20 kilometers, comprising four structural layers: graded gravel cushion, cement-stabilized macadam sub-base, lower base course, and upper base course. All paving areas and material usage indicators have reached 100%. The project team adopted a "dual-machine joint paving" process, using a loose paving thickness of 26 cm and a compacted thickness of 20 cm as the standard, achieving single-lane one-time paving and rolling compaction, significantly improving construction efficiency and pavement smoothness.
The Ziyang Specialized and New Industrial Park Phase I project has achieved full structural topping-out. The project encompasses 28 intelligent manufacturing workshops and related supporting facilities, with a total construction area of approximately 350,000 square meters. It is a core industrial project for Ziyang to build a gateway for Chengdu-Chongqing industrial collaboration and cultivate specialized and new enterprises. The project innovatively adopted "UAV aerial survey + 3D laser scanning + manual grid re-measurement" to generate high-precision topographic mapping data, providing reliable support for site leveling construction. A permanent-temporary combined construction model was employed, integrating the planning and simultaneous construction of temporary construction roads and 3.1 kilometers of permanent municipal roads, effectively reducing duplicate construction.
The Xiangshui Shoreline Restoration and Ecological Enhancement Project has passed completion acceptance. The project integrates multiple professional disciplines including river ecological management, landscape enhancement, supporting buildings, municipal pipelines, bridges, and renovation of old houses. The project team innovatively adopted a prefabricated pipe pile retaining wall technology to reduce ecological damage and save costs. River management utilized an ecological buffer zone combined with an aquatic plant purification system to ensure stable water quality compliance. The roofs of 26 single buildings adopted a composite structure of glued laminated timber beams and metal roofing, with each functional layer independently set and tightly bonded, effectively solving industry pain points such as poor waterproof reliability and weak thermal insulation of traditional timber roofs.
The Phase II project of the LPG storage tank project for RDS Company in the Netherlands has been completed. The technical indicators of the 24 LPG storage tanks, each with a capacity of 380 cubic meters, meet the certification standards of the internationally authoritative Lloyd's Register. Each storage tank has a diameter of 4 meters, a length of 26 meters, and a height of 6 meters. Through standardization of welding processes and optimization of segmental assembly and closure procedures, the technical team shortened the welding cycle for a single tank by 30%. The innovative "annealing weld bead method" effectively controlled the hardness of the heat-affected zone and crack risk. The developed "low-strength backing + equal-strength filling" welding material matching scheme filled a domestic gap in welding technology for P690QL1 steel marine liquid tanks.
The Yichang Yiling Yangtze River Bridge project has opened to full traffic. The mainline of the project is approximately 5 kilometers long, with a total viaduct length of 3.9 kilometers. After opening, it will connect Yiqiao Road, Gangyao Road, Juxiang Avenue, and Yihuang Road, seamlessly linking the Fanba Expressway and Yiba Expressway, completely unblocking the cross-river traffic bottleneck in the central urban area. The project team innovatively applied a "lower column + upper disc-buckle scaffold" minimal-support system, enabling box girder construction on the bridge while maintaining two-way four-lane traffic underneath.
The Qingshan District Erjie Fang Construction Project has fully emerged from ground level. The project has a total construction area of approximately 86,000 square meters, mainly consisting of 6 high-rise residential buildings, commercial facilities, and a two-story basement, while simultaneously improving living, transportation, education, commercial, and medical supporting facilities. Facing challenges such as a confined site, complex components, and tight construction sequences, the project team focused on standardized management, optimized construction techniques, implemented safety and civilized construction control measures, efficiently advanced underground structure construction, and achieved the milestone target on schedule with guaranteed quality and quantity.
The Guangming Science and Technology Home Project has achieved structural topping-out. The project has a total construction area of approximately 98,300 square meters. Upon completion, it will become an iconic scientific gateway for external exchange and display within Guangming Science City. Facing challenges such as large underground column caps and difficult construction of long-span structures, the project team strictly controlled project quality and built a solid safety production defense line, implementing control measures from five dimensions: scheme, erection, monitoring, management, and acceptance, successfully completing the topping-out goal.
The Yunnan Dianzhong Affordable Housing Project has successfully passed the main structure acceptance. The project includes 21 residential buildings, 1 kindergarten, 2 commercial complexes, and related supporting facilities. Upon completion, it will provide 2,500 affordable housing units, meeting the living needs of over 5,000 people. The project team implemented systems such as model guidance, three-level inspection, and site supervision, strictly controlled key processes, addressed common quality defects, and firmly upheld quality standards.
The Central Plains Automotive Industry" target="_blank">New Energy Vehicle College project has fully emerged from ground level. The project has a total construction area of approximately 224,900 square meters. Upon completion, it will build a solid bridge for deep integration of industry and education, cultivating a large number of high-quality, application-oriented talents for the new energy vehicle field. The project team comprehensively reversed the construction schedule, held daily on-site coordination meetings, and dynamically optimized process interfaces. They strictly implemented full-process supervision of steel reinforcement, formwork, and concrete, and conducted item-by-item acceptance of key processes such as waterproof membranes, anti-floating anchors, and post-cast strips, firmly adhering to project quality standards.
The first residential building of the Shandong Ningjin Shantytown Renovation Project has achieved structural topping-out. The project is a key livelihood project for promoting new-type urbanization in Dezhou City, with a total construction area of approximately 236,700 square meters, building 20 high-rise residential buildings, and providing 1,614 resettlement housing units upon completion. Facing hot and sweltering weather, the project team prepared a specialized pouring construction plan in advance, conducted comprehensive technical briefings on key processes such as formwork support systems, concealed reinforcement, concrete pouring sequence, and layered vibration, and performed real-time monitoring and control of slab elevation, thickness, and flatness to ensure the quality of the structural entity meets standards.
