摘要: | 便橋建造對於救災來說相當重要。而因為技術人力短缺與極端氣候的影響,施工自動化科技需要被應用在橋梁建造上。傳統的快速橋梁建造法使用輕質材料與螺栓連接之節塊結構,搭配許多人力與機具的使用完成一個快速建造的節塊橋樑。然而,不管是人力還是機具,兩者在救災時都難以取得。另外,一個自動化的橋梁建造工程需要有河流觀測系統來觀測河流狀態,以防河流變化造成的災害,但河流流速特徵難以捉摸,每個河流都要客製化找出該河流的特徵來做流速分析。為了要解決上述施工自動化與河流觀測的問題,本研究開發了一個結構接頭設計搭配一個特殊施工法、一個吊車控制方法來減緩被吊物也就是橋梁節塊的擺盪,和一個使用群眾來觀測河流流速之方法。數值模型與小型實驗模型驗證了本研究提出的結構接頭設計與吊車控制方法。再者,簡化後的吊車控制法則以伸縮式吊車驗證;最後流速測量法則以一群受試者測試其可行性。本研究提出之自動化橋梁建造系統利用了創新橋梁接頭設計來達到自動化組裝橋梁節塊的目的、減少吊車吊裝節塊時的晃動來減低被吊物碰撞與掉落風險、監控河流流速狀況來警示是否該撤離該施工地段。 Temporary bridge construction is essential in disaster relief. Due to skilled worker shortage and adverse weather conditions, the bridge construction needs construction automation technology. The conventional temporary bridge construction uses light-weighted material and bolt-connected segmental structures and employs many construction workers and machines. Additionally, an automated bridge construction requires a river observation system to monitor the river flow condition in case of immediate evacuation. To resolve these problems, this research developed a structural connector design with a specific construction method, a crane control method reducing the payload sway, and a flow velocity measurement approach with crowd-sourcing. The numerical simulation and scaled experiment verifies the designed structural connector and the control method. Moreover, the simplified control method has been tested on a telescopic crane. The developed flow velocity measurement method is also verified by a user test. The proposed automated bridge construction system takes advantage of the connector design to assemble the bridge segments, reduces the segment sway to mitigate the construction risks, and monitors the river flows effectively. |
