Purpose & Scientific Principle
Through model display and hands-on experience, the exhibition allows the audience to use their imagination to build bridges, understand the types of bridges and the stress structures of different bridges, guide children to build their own bridges, and display the spirit of innovation and creativity.
How to Operate
There are two interactive exhibition items. A large bridge model (made of EVA) is set up on the ground. The audience can assemble and climb on the built bridge.
A booth is set up against the wall, with bridge instructions and five bridge assembly models placed on the table, namely beam bridge, arch bridge, rigid frame bridge, cable load-bearing bridge, and composite system bridge. Each type of bridge has a different shape and force-bearing system. The audience can build it based on the actual model through building blocks and feel the force-bearing principle.
The first step of building a bridge is to dig a hole to make the foundation, the second step is to erect pillars on the foundation, and the third step is to connect the top surfaces of the pillars with panels. During the construction process of the bridge, the structure is mainly divided into four basic parts, the upper structure, the lower structure support system and ancillary facilities. Digging holes and erecting pillars belong to the lower structure, while panels and pillars belong to the upper structure. The bridge superstructure is usually also called the bridge span structure, which is the main load-bearing structure that crosses obstacles when the line is interrupted: the substructure includes piers, abutments and foundations; bridge ancillary facilities include bridge deck systems, expansion joints, bridge head slabs and tapered slope protection, etc. The bridge deck system includes bridge deck paving (or lane paving), drainage and waterproofing systems, railings (or anti-collision railings), lighting, etc. According to the structural system, there are four basic systems: beam bridge, arch bridge, rigid frame bridge, and suspension bridge. There are other combination systems composed of several basic systems. Regardless of the structure of the bridge, the construction steps are similar, starting with the foundation, abutments, and piers of the substructure, then constructing the superstructure, and finally installing ancillary facilities.
