Description
本發明係關於一種橋樑用楔型推進裝置及其施工方法,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及其施工方法。The invention relates to a wedge-type propulsion device for bridges and a construction method thereof, in particular to a large-scale steel bridge or a prestressed concrete box girder which can reduce construction costs, be easy to assemble, and improve stability and safety during displacement propulsion operations. Wedge type propulsion device and construction method thereof.
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 press, at present, large-scale steel bridges or prestressed concrete box girders are undergoing displacement advancement construction operations. Because the weight of the box girders is more than 1,000 metric tons, they cannot be moved by cranes.
