Two Scientific Research Achievements of Xindafang Successfully Pass Evaluation: Achieve International Advanced Level
On June 27, a research achievement appraisal committee composed of dozens of industry experts from Henan Province—including the Key Laboratory of Mechanical Design and Transmission Systems of Henan Province, the Zhengzhou Research Institute of Machinery, Zhengzhou University, Henan University of Science and Technology, the Henan Equipment Manufacturing Association, Liming Heavy Industry, Wanchuang Intelligent Manufacturing, and other institutions—visited Xinfada to evaluate two of Xinfada’s research achievements: “Research and Application of the DCY40E Pipeline Transportation and Installation Trolley” and “Research and Application of the DGC75 Crawler-Type Pipe-Handling Trolley.”
The DCY40E pipeline transport and installation trolley is an integrated “mechanical–electrical–hydraulic” transport system developed by Xinfada, drawing on more than 20 years of expertise in the R&D of specialized vehicles and tailored to the unique operational conditions of transporting and installing ultra-large-diameter pipelines within deeply buried tunnels. It is specifically designed to meet the demanding requirements of ultra-large-diameter water-diversion and water-regulation projects in deep-buried tunnel environments, addressing the challenges posed by narrow clearances between the pipeline and the tunnel lining as well as the logistical and installation tasks associated with transporting and erecting extra-long, extra-large-diameter steel pipes inside tunnels. The trolley incorporates mature technologies such as a hydrostatic drive system, independent hydraulic suspension, and independent hydraulic steering, ensuring high levels of safety and reliability. In addition, it represents the first application of clean-energy technology in tunnel material-handling vehicles and introduces several pioneering innovations, including an eight-shaped wheel travel mechanism, a rotary pipe-supporting device, arc-surface travel posture adjustment, and pipeline self-adaptive alignment. These advancements reduce environmental pollution, alleviate the physical workload of construction personnel, and enhance the trolley’s adaptability to curved tunnel surfaces, thereby improving its throughput, operational efficiency, and safety. As such, the DCY40E trolley falls within the realm of intelligent, high-end construction machinery and equipment. Its significance extends beyond enhancing the current capacity for large-scale water-diversion projects; it also lays a solid technological foundation for future, larger-scale, and more complex water-infrastructure developments, steering the industry toward greater efficiency, safety, and intelligence.
Currently, the pipeline transportation and installation trolley has been successfully deployed in the Pearl River Delta Water Resources Allocation Project, which is invested in, constructed, and operated by Guangdong Yuehai Water Services Co., Ltd., as well as in the Mao’ertuo Tunnel Project of the Xiangjiaba Main Canal in Yibin City, Sichuan Province, representing a major breakthrough in the technology for transporting and installing heavy components in large-scale water conservancy projects involving water diversion and allocation.
“The Research and Development and Application of the DGC75 Crawler-Type Pipe-Alignment Cart” is a specialized piece of equipment for pipeline transfer and jointing, jointly developed by Xindafang and China Water Conservancy and Hydropower Fourth Engineering Bureau Co., Ltd. to address the low construction efficiency, high safety risks, and significant installation challenges associated with PCCP pipeline construction in traditional water-resource allocation projects. The successful development of the DGC75 crawler-type pipe-alignment cart has resolved the difficulties in installing PCCP pipelines on steep-gradient water-conveyance lines and beneath high-voltage power lines, while simultaneously enhancing construction efficiency and reducing construction risks. This breakthrough in hydraulic-engineering construction equipment departs from the conventional approach of using crawler cranes for PCCP pipeline transfer and jointing, instead introducing an intelligent, highly automated, and information-integrated construction system designed specifically for transferring and joining PCCP pipelines within open-cut excavations—a technological innovation that represents a domestic first.
This technological achievement has been successfully applied to the construction of Lot D1 of the Guangdong Water Resources Allocation Project in the Beibu Gulf Region, where the product’s unique design, comprehensive functionality, and substantial contributions to construction operations have earned high praise from the client. The R&D of this product is of great significance for reducing the physical workload of construction personnel, enhancing construction efficiency, and advancing the development of intelligent construction equipment; it falls squarely within the realm of cutting-edge, intelligent “construction machinery and equipment.” In terms of both economic benefits and construction efficiency, as well as the degree of automation, it outperforms other similar devices, setting new records in this field and for this particular construction method. This breakthrough has elevated the level of indigenous R&D in PCCP pipeline construction equipment to a new height, with far-reaching historical implications for improving project quality and accelerating project delivery.
After hearing the project team’s report and reviewing the relevant technical documentation, the appraisal committee conducted inquiries and on-site discussions and reached the following appraisal opinion: Both research achievements meet the design requirements in terms of technical specifications, feature convenient whole-machine operation, high safety and reliability, and high operational efficiency, thereby filling a gap in the industry and delivering significant economic and social benefits.
The appraisal committee ultimately approved the results, noting that both achievements are highly innovative, possess independent intellectual property rights, and that the overall technology has reached an internationally advanced level. The committee unanimously agreed to pass the appraisal and recommended further expanding the promotion and application of these results.
