摘要
高铁营业线增站工程是在不停办客运、接触网带27. 5 k V高压电的情况下实施,长跨天桥跨多股接触网吊装要克服以下困难:施工时间短,安装精度要求高,吊装风险系数大。基此必须选择适宜的施工方法,做好充分准备工作,设置完善安全防护措施,确保高铁运输安全万无一失。仙游动车站跨线钢结构天桥,就是应用了该技术理念指导施工,圆满成功地在天窗点时间内安全、正点完成了吊装任务。
New station project of high-speed railway business line is implemented under the condition of non-stop passenger transportation and contact network with 27. 5 Kv high-voltage power. The large-span platform bridge should overcome the following difficulties across the multi-strand contact network: short construction time,high installation accuracy requirements,and high risk coefficient of hoisting. It is necessary to select appropriate construction methods,fully prepare for work,and set up perfect safety protection measures to ensure the safety of high-speed rail transportation. Using this technology to guide the construction,it is possible to complete the lifting task at the skylight pointsafely and punctually. The construction technology can be promoted and applied in the hoisting of large-span platform bridge across the railway business line.
