Description
本創作係關於一種橋樑用楔型推進裝置,尤指一種大型鋼橋或預力混凝土箱樑在位移推進作業中,能降低施工成本、易於組裝,且提升平穩性及安全性的楔型推進裝置。This creation is about a wedge-shaped propulsion device for bridges, especially a wedge-shaped propulsion device that reduces construction costs, is easy to assemble, and improves stability and safety during displacement propulsion operations of large steel bridges or prestressed concrete box beams. .
按,目前大型鋼橋或預力混凝土箱樑在位移推進施工作業,因箱樑的重量有上千公噸以上,無法使用吊車搬移,大部份採用頂推拖拉式法,利用在橋墩上設置臨時墩、千斤頂及軌道,推進或牽引拖動箱樑在軌道上滑移至安裝位置。According to the current situation, large-scale steel bridges or pre-stressed concrete box girder are moving forward for construction operations. Because the box girder weighs more than 1,000 metric tons, it cannot be moved by crane. Most of them use the push-pull method and use temporary push-pull methods on the bridge piers. Piers, jacks and tracks, pushing or pulling the box girder to slide on the track to the installation position.
惟,在施工作業時,箱樑在位移推進過程中,利用千斤頂牽拉鋼索在設置平移的軌道滑移,因靜止箱樑推動時摩擦力大,需要更大的動力牽引,而頂推拖拉時需要巨大的水平力,以克服靜磨擦力,且臨時墩需要另外設置、較大剛度支撐及隨時調整牽引力,而臨時墩或橋墩各支力點,容易受力不均及水平荷載過大,造成橋墩混凝土裂開、設備損壞等問題,影響橋墩結構及箱樑位移推進的平穩性及安全性,本創作人有鑑於此,遂深入進行研究改良,遂有本創作產生。However, during the construction operation, the box girder is in the process of displacement and advancement, and the jack is used to pull the steel cable to slide on the set translational track. Because the static box girder is pushed by the friction force is large, more power is required for traction. Huge horizontal force is needed to overcome static friction, and temporary piers need to be set up separately, supported with greater rigidity and traction can be adjusted at any time. However, temporary piers or pier supporting points are prone to uneven forces and excessive horizontal loads, resulting in bridge piers. Concrete cracking, equipment damage and other issues affect the stability and safety of the bridge pier structure and box girder displacement advancement. In view of this, the author conducted in-depth research and improvement, and this creation was born.
