Recently, the 800,000-ton siloxane production and related downstream processing project for silicon-based materials in Xinjiang, undertaken by Shaanxi Huajian Xi’an Company, successfully completed all its civil engineering tasks ahead of the winter break. This achievement lays a solid foundation for the subsequent installation of equipment and the commissioning of the project, demonstrating the practical commitment of state-owned enterprises. As a key energy and chemical project with a total investment of over 10 billion yuan, the 800,000-ton siloxane project in Xinjiang’s Qiya is being constructed in three phases, with the aim of improving the layout of the \"coal-electricity-silicon\" industrial chain. The civil engineering projects undertaken by the Xi’an company include key elements such as the tank farm foundations, unit synthesis systems, slurry high-boiling units, incineration facilities, and pipe gallery foundations; these projects involve a wide range of construction tasks and require high technical standards. By the end of the winter break, 66,850.52 m³ of earthwork had been completed, 10,711.755 m³ of concrete pouring was done, 760 tons of rebar were installed, 11,317 m² of formwork was set up, 15,558 m² of foundation anti-corrosion treatment was carried out, 39,287 m³ of soil backfilling was completed, and 7,987.78 meters of protective measures were installed along the edges; all the civil engineering work related to the foundations and the first-level pipeline installation was completed to a high standard before the New Year. The Jungdong region experiences early and severe winters; since late November, the lowest temperatures have dropped below -21°C. Harsh weather conditions such as frozen soil, strong winds, and ice and snow pose significant challenges to concrete construction and foundation curing. At the same time, the approaching winter break has led to a tighter supply of building materials and disruptions in transportation on the supplier’s side; these combined pressures pose a severe challenge to the construction progress. To ensure that the nodes meet their obligations, the project team developed a specialized plan for dealing with cold conditions: technically, a three-pronged approach of \"hot water mixing + antifreeze + insulation shelters\" was adopted, along with 24-hour temperature monitoring; furthermore, an innovative insulation system for the pipeline foundations consisting of \"quilts + thermal insulation covers + hot air curtains\" was implemented ； Optimize management processes by implementing a two-shift system for rebar processing, take advantage of the period of higher temperatures during midday to carry out outdoor work, and coordinate closely to ensure a steady supply of materials ； In terms of safety and quality, special training on cold and slip prevention is provided, sufficient protective equipment is supplied, a \"three-inspections and three-checks\" system is established, and \"actual measurement\" is implemented for key areas. The workers from the chemical construction team braved the snow and extreme cold, and completed the foundation construction for the slurry high-boiling and monomer synthesis units by the end of November – just within a few dozen days. The work was approved by both the supervision team and the project owner, with a 100% quality compliance rate. “The team at the Xi’an office overcame the extreme cold conditions through hard work, completing the civil engineering tasks ahead of schedule and thus securing valuable time for the further progress of the project! ”The relevant responsible person from the owner’s party gave high praise to the project construction team. The successful completion of this construction project demonstrates Shaanxi Huajian’s technical expertise and ability to meet commitments in the construction of large-scale chemical projects in cold regions. Next, the project team will use the winter break to conduct a technical review, in order to prepare for the installation of the equipment once work resumes in spring, and continue to contribute to the high-quality development of Xinjiang’s energy and chemical industry.
