Recently, Jidong Haitian Cement Wenxi 2 million tons/year aggregate project, EPC contracted by Hebei Building Material Industry Design and Research Institute Co., Ltd. (Hereinafter referred to as "Hebei Building Material Design Institute"), affiliated to Jinyu Group Research Institute, has successfully passed the completion acceptance and formally put into operation. As a key green building material project in the region, its completion will effectively fill the gap in the regional market, supply 2 million tons of high-quality aggregates annually, provide a stable guarantee for infrastructure construction and commercial concrete market in southern Shanxi, and mark a solid step in upgrading the green building material industry.
In recent years, Hebei Building Material Design Institute has completed the planning, design and construction of new dry cement production lines, aggregate production lines and related non-metallic mines in many large and medium-sized enterprises by virtue of its rich experience in production line design, consultation and construction. It took only four months for the project to start and put into operation, setting a new record for the construction speed of similar projects. In the construction of this project, we should give full play to the advantages of "platform plus" integration of resources, and achieve breakthroughs in construction efficiency through three innovative measures.
Multi-dimensional collaborative design to improve efficiency. The "stepped crushing and screening process" is innovatively adopted, and the three-dimensional layout is implemented in combination with the natural elevation difference terrain, which organically integrates the auxiliary workshop with the main workshop, saves 14% of land and shortens the construction period by 10%. By optimizing the layout of column support and roof support, the screening workshop realizes the frame structure without lateral displacement, which is different from the traditional steel frame with lateral displacement door, and reduces the steel consumption by about 30%. Through BIM technology, the precise docking of equipment parameters and civil engineering structure is realized, and the design change rate is reduced.
Dynamic closed-loop management mechanism. The project team incorporates project procurement into the design process and construction requirements into the design management. On the premise of ensuring quality and safety, measures such as material list first, drawing in batches, stage design disclosure and simultaneous construction are implemented. The implementation of the project is no longer the first design and then construction, but the trinity of design, procurement and construction under the coordination of multiple disciplines and units.
Dynamic control of node duration. Establish a two-level management structure of "general contractor-subcontractor", a three-level progress control system of "daily statistics-weekly calibration-monthly adjustment", dynamically adjust the work plan closely around the project objectives, take measures in advance, take measures in the event, and actively coordinate afterwards, so as to fully mobilize the participating units to ensure the nodes and rush the construction period. Achieve a maximum monthly progress increase of 15%.
Innovation-driven, set up green intelligent construction model
scheme design green concept. The dust collection system of the production line adopts innovative design to recycle 100% of the collected dust for cement clinker production, so as to realize zero waste discharge in the whole process of aggregate production. The dust emission concentration is stable below 10 mg/m ³, and the powder content of the finished aggregate is strictly controlled within 0.5%. Reach the leading level in the industry. Stepped chute technology is adopted and the wear-resistant design concept of cement production line is integrated, which reduces noise and equipment impact compared with traditional straight chute.
Intelligent project innovation concept. It is equipped with self-developed DCS control system, integrating nearly 500 intelligent monitoring points such as field detection instruments and equipment status monitoring, so as to realize the automatic operation of the whole process from raw material crushing to finished product delivery, and ensure production safety, environmental protection and high efficiency. The system synchronously realizes the integrated intelligent service from raw materials entering the factory to finished products shipping. The concept of
resource integration and coordination. Relying on the supply chain resource bank of Jinyu Group, more than 40 high-quality equipment suppliers are precisely integrated, and advanced equipment such as high-efficiency motors and intelligent delivery systems are integrated. Through the just-in-time procurement strategy, the equipment delivery process is optimized, and the equipment delivery cycle is shortened by 30% on the premise of ensuring technological advancement and quality reliability. The successful implementation of this
project marks a new leap forward in the EPC general contracting field of green building materials in Hebei Building Materials Design Institute. As a "high-tech enterprise" and a "specialized, special and new" design enterprise in Hebei Province, Hebei Building Material Design Institute has formed a core technology system in key areas such as energy-saving and consumption-reducing transformation of cement kilns, collaborative disposal of solid waste and hazardous waste, environmental protection and emission reduction, green mines, intelligent upgrading and general contracting technical services. Provide systematic solutions for the building materials industry to achieve the goal of "double carbon", continue to give full play to the professional advantages, and better serve the high-quality development of Jinyu Group and the building materials industry with "first-class design, first-class service, and create first-class quality projects".
