Dongfang Yuhong: HDPE High Polymer Self-Adhesive Waterproof Membrane Participates in Multiple Key Projects, Launches Upgraded YH-101 Oil-Based Polyurethane Grouting Liquid to Solve Leakage Problems

According to reports from the news agency, on August 28, an investor approached...Dongfang YuhongWhat aspects can companies support in the construction and renovation of urban underground pipeline networks and the construction of underground comprehensive pipe corridors? For this,Oriental YuhongOn September 19, the company responded on the investor interaction platform that it covers a diversified range of business sectors including construction waterproofing, civil building materials, mortar powder, architectural coatings, energy-saving insulation, adhesives, pipe industry, building renovation, new energy, non-woven fabrics, specialty films, and emulsions. Its products and services are widely used in various fields such as residential construction, high-speed railways, subways and urban railways, highways and urban bridges, airports and water conservancy facilities, comprehensive utility tunnels, affordable housing, renovation of old houses, improvement of urban villages, and urban renewal. In the field of underground space engineering construction, the HDPE polymer self-adhesive waterproof membrane developed by the company has participated in the construction of Beijing Line 15.Nanchang Honggu Tunnel, JiangxiKey projects such as the Beijing International Horticultural Exposition park's peripheral underground comprehensive pipe gallery, the comprehensive pipe gallery along the Beijing Daxing International Airport Expressway, the Liupanshui underground comprehensive pipe gallery, and the Beijing Chaoyang Station building project of the Beijing-Harbin High-Speed Railway have been widely applied in underground space engineering fields such as subways, public (rail) tunnels, comprehensive pipe galleries, and underground buildings. Additionally, in response to the leakage challenges of underground comprehensive pipe galleries, the company launched the upgraded YH-101 oil-based polyurethane grouting material in 2023. This grouting material can quickly foam and expand upon contact with water, effectively filling structural cracks and maintaining stable sealing performance in harsh environments with prolonged water immersion and alternating wet-dry cycles, achieving efficient remediation of complex leakage scenarios. It has been successfully applied in numerous engineering maintenance projects nationwide. In addition, the company's holding subsidiary...China Technology Construction Engineering Co., Ltd.Focus on the industry pain points and key problems in the subdivision of underground engineering, innovating precise combination solutions for detection, monitoring, systematic treatment of structural diseases, and stratum improvement and reinforcement, to provide assurance for urban underground engineering construction.
