在人们的印象中,桥梁,似乎永远是架设而成的。而京九铁路泰和赣江特大桥却是用钢筋混凝土从墩身顶部直接悬空灌注而成的。施工过程中,墩身顶部的梁端所构成的“T”字形分段均衡地向两端延伸,象巨人伸出的巨臂一样,最后在空中“拉手”合拢成一个连续整体梁。这种桥梁的专业术语叫“预应力钢筋混凝土悬臂箱型梁”,简称“悬灌梁”或“悬浇梁”。 在京九铁路线上,由于泰和赣江特大桥所采用的这种施工方法是目前桥梁施工的新型技术,是我国
In people’s minds, the bridge seems to always be erected. The Beijing-Kowloon Railway Taihe Gan River Bridge is the use of concrete from the top of the pier directly suspended vacant perfusion made. During the construction, the “T” -shaped section formed by the beam ends at the top of the pier body extends evenly to both ends, like the giants extended by the giant, and finally “handles” are folded into a continuous monolithic beam in the air. The technical term for this bridge is “prestressed reinforced concrete cantilever box girder”, referred to as “cantilever beam” or “cantilever beam.” On the Beijing-Kowloon Railway line, due to the construction method adopted by Taihe Ganjiang River Bridge, it is a new type of technology used in bridge construction.
