两孔32m铁路预应力混凝土梁整体拖拉拆除施工

The Whole Demolition of Prestressed Concrete Beams of the Two-span 32-meter Railway

介绍位于通航运河上的两孔32m铁路预应力混凝土T梁通过结构受力体系转换,由两孔简支梁变成两孔一联连续梁,采用连续顶推移位方法,从河道内移至堤外进行拆除的施工方法。

The article introduces the construction method of moving the prestressed concrete T beams of the two- span 32-meter railway, which was located over the navigable canal from the river course to the dike, through the transformation of the structure force system -from a simple two -span beam to a continuous beam and the method of incremental launching construction.
