The Rolling Bridge, UK
滾石橋,英國
Conceived by British designer Thomas Heatherwick,
this bridge is the only moveable bridge on the list.
Eight triangular sections are hinged together and
connected above by two part links that can be
rolled up towards the deck by concealed hydraulic pistons.
When extended, it is 12 meters long and resembles a
conventional steel and timber foot bridge. However,
to allow the passage of boats, the bridge curls up
until its two ends join.
由英國設計師托馬斯•赫斯維克的設想,
這座橋是名單上唯一可移動的橋樑。
八個三角形截面鉸接再一起並且由
兩部分組成的鏈接可以被捲起朝甲板
通過隱蔽液壓活塞上方連接。當擴展,
它長12米,類似於傳統的鋼材和木材橋繳腳。
但是,為了使船的通道,橋捲直至其兩端連接。
