Countermeasures to Promote the Training of Prefabricated Construction Talents for Architectural Design Majors in Vocational Colleges

To concentrate on cultivating prefabricated construction talents for architectural design majors in vocational colleges in China,we should adhere to the basic principles of professional coordinated development and integration of production,teaching,and research to determine the teaching objectives and contents,set up a double-teacher teaching team,and provide sufficient resources and funds.Specifically,it is necessary to optimize the curriculum system with the guidance of professional groups,create teaching situations with information platforms,introduce Building Information Modeling(BIM)technology to connect with the actual situation,adhere to the combination of education and training to improve the practice mechanism of school-enterprise cooperation,deepen the integration pattern of post-course certificate competition,and follow the ideological and political teaching route of professional course to realize the comprehensive improvement of students’knowledge,skills,and professional quality.

Advancements and Applications of Polyurethane Curing Technology in Railway Track Bed Construction in China

This paper examines the application of polyurethane curing technology in the construction of railway track beds,with a specific focus on its implementation in China’s rapidly developing railway infrastructure.The study begins by identifying the limitations of traditional ballasted track beds,especially under the demands of high-speed and heavyload railways.It then methodically analyzes the advantages of polyurethane-cured track beds,highlighting their improved mechanical properties,including enhanced stability and durability.The paper further explores the benefits of transitioning to prefabricated polyurethane track beds,emphasizing significant cost reductions,better construction quality,and enhanced maintainability.Through a detailed review of experimental data and practical applications,the paper demonstrates the efficacy of polyurethane track beds in various railway settings.A critical part of the research involves optimizing the structural parameters of polyurethane track beds to achieve the best balance of mechanical and damping properties.The conclusion of the paper underscores the potential of polyurethane curing technology as a transformative approach to railway track bed construction,offering a solution to the challenges posed by traditional methods and aligning with the evolving needs of modern railways.
