Construction method for door-shaped pier crossing existing line
The invention belongs to the technical field of bridge construction, and particularly relates to a construction method of a portal pier crossing an existing line, which comprises the following steps of: 1) processing a construction area field, and establishing a hoisting platform and an assembling platform; (2) steel stand column hoisting; (3) assembling the steel cross beams; and (4) the steel cross beam is hoisted, specifically, a temporary fixing plate is welded to the steel cross beam before hoisting, a positioning prompt assembly is arranged on the temporary fixing plate, and the positioning prompt assembly comprises a prompt lamp, a mounting threaded column, a sliding piece, a conductive piece I, a conductive piece II and an elastic piece used for connecting the mounting threaded column and the sliding piece. The temporary fixing plate is provided with a transverse through hole used for installing the positioning prompting assembly, one end of the sliding piece is spherical and protrudes out of the transverse through hole, and the prompting lamp is powered on and turned on after the conductive piece I makes contact with the conductive piece II. And 5) connecting the steel cross beam with the steel stand column. The positioning prompting assembly is used for prompting a worker whether the steel cross beam is accurately aligned with the steel stand column or not at night, the worker is prevented from repeatedly adjusting the steel cross beam, and the construction efficiency is improved.
本发明属于桥梁施工技术领域，具体涉及一种跨越既有线门型墩施工方法，包括以下步骤：1)施工区域场坪处理，建立吊装平台和拼装平台；2)钢立柱吊装；3)钢横梁拼装；4)钢横梁吊装：吊装前在钢横梁上焊接临时固定板，临时固定板上设有定位提示组件，定位提示组件包括提示灯、安装螺纹柱、滑移件、导电件Ⅰ、导电件Ⅱ和用于连接安装螺纹柱与滑移件的弹性件，临时固定板上开设有用于安装定位提示组件的横向通孔，滑移件的一端呈球面且冒出横向通孔，提示灯在导电件Ⅰ和导电件Ⅱ接触后通电亮起；5)钢横梁与钢立柱连接。本发明利用定位提示组件在夜间提示工人钢横梁是否与钢立柱对位准确，避免工人反复调节钢横梁，提高施工效率。
