Temporary temporary beam construction method for jacking multi-span frame box culvert underneath passing railway station track group
The invention discloses a temporary auxiliary beam construction method for jacking a multi-span frame box culvert underneath passing railway station track group. The temporary auxiliary beam construction method comprises the following steps that temporary supports are built; pulling out the railway sleepers; inserting a cross beam; the longitudinal beams are moved to the temporary supports; assembling and connecting the cross beams and the longitudinal beams; a foundation below the railway track is excavated, and a plurality of pile foundations are constructed and formed; constructing and forming a strip-shaped foundation beam; the longitudinal beams are detached and replaced to the strip-shaped foundation beams; if the pile foundations are on the box culvert jacking line, the pile foundations, on the jacking line, of the frame box culvert are chiseled away, and multi-span frame box culvert crossing railway track group construction jacking is conducted; if the pile foundations are not on the box culvert jacking line, the pile foundations do not need to be chiseled away to add steel supports; and after each frame culvert is jacked, roadbed backfilling, temporary auxiliary beam moving and next box culvert jacking are conducted till the box culverts are jacked completely, and the auxiliary beams are removed. According to the method, in the process that the multi-span frame box culvert downwards passes through the railway track group, a train can still keep passing on the railway track group.
本申请公开了多跨框架箱涵下穿铁路股道群顶进用临时便梁施工方法，包括以下步骤：筑建临时支座；抽出铁道枕木；插入横梁；将纵梁移至临时支座上；将横梁与纵梁之间组装连接；将铁路股道下方的地基进行开挖并施工成型若干个桩基；施工成型条形基础梁；将纵梁脱换架至条形基础梁上；若桩基在箱涵顶进线路上，凿除框架箱涵在顶进路线上的桩基并进行多跨框架箱涵穿越铁路股道群施工顶进；若桩基不在箱涵顶进线路上，不需凿除桩基增加钢支撑；每一个框架想涵顶进完成后，都进行回填路基，移动临时便梁，进行下一个箱涵顶进，直至箱涵全部顶进完成移除便梁。本申请实现了在多跨框架箱涵下穿铁路股道群的过程中，列车依旧可以在铁路股道群上保持通行。
