Single-line single-span railway steel truss girder dragging installation construction method and single-line single-span railway
The invention relates to a single-line single-span railway steel truss girder dragging installation construction method. The method comprises the following construction steps of S1, temporary supportand slide way girder installation, including behind-abutment roadbed section temporary support and slide way girder installation, inter-abutment temporary support and slide way girder installation, inter-pier temporary support and slide way girder installation and pier side temporary support and slide way girder installation; S2, front guide beam and steel truss girder behind-abutment assembling;S3, manufacturing and installing of a sliding block, including arrangement of the sliding block at a lower chord part between the large sections of the steel truss girder; S4, manufacturing and installing of a dragging device, including manufacturing and installing of a jack dragging horizontal counter-force seat, manufacturing and installing a rear anchoring device and penetrating and dragging ofa steel strand bundle; S5, dragging of a part of the steel truss girder; S6, dismounting of the temporary support, including dismounting of the sliding block and dismounting of the support; and S7, beam falling in place. The invention further relates to a single-line single-span railway obtained through the construction method. The construction method is advanced, engineering quality, safety andcontrollability are achieved, and the construction period is effectively shortened.
本发明涉及一种单线单跨铁路钢桁梁拖拉安装施工方法，包括以下施工步骤：S1、临时支架及滑道梁安装，包括台后路基段临时支架及滑道梁安装、台墩间临时支架及滑道梁安装、墩间临时支架及滑道梁安装和墩侧临时支架及滑道梁安装；S2、前导梁及钢桁梁台后组拼；S3、滑块制作及安装，在钢桁梁大节间下弦杆部位设置滑块；S4、拖拉装置制安，包括千斤顶拖拉水平反力座制安、后锚装置制安和穿牵引钢绞线束；S5、钢桁梁拖拉部分；S6、拆除临时支架，包括滑块拆除和支架拆除；S7、落梁就位。本发明还涉及由上述所述的施工方法获得的一种单线单跨铁路。本发明施工工艺先进、工程质量、安全可控、有效缩短工期。
