Description

Technical Field

[0002] The wooden arch bridge, also known as the Rainbow Bridge, is a unique style in traditional bridge construction. It is famous for its unique structural method and architectural aesthetics. Its main feature is the use of wood as the main building material, and the stability and durability of the bridge are achieved through ingenious structural design.

[0003] Bridge structure teaching: Through the teaching design of bridges, students can understand the design process and engineering principles of bridges and cultivate their engineering thinking ability. Through explanations and case analysis, teachers guide students to analyze problems, propose solutions, and conduct engineering design and optimization. Through this process, students can exercise and cultivate their own innovation, analysis and problem-solving abilities, and can improve their practical operation ability through actual production and construction, understand the properties of materials and the strength of structures, and also allow students to truly experience the process of engineering design and construction, and cultivate students' teamwork spirit.

[0004] When teaching traditional bridge structures, sandbox models are usually used for students to make and build bridge structures according to the teaching content. However, traditional sandbox models of bridge structures do not have a testing function, which leads to the need for unified testing after students have completed the production and construction.
