Girder Erecting Techniques with JQ900E Bridge Erecting Machine

沪宁城际铁路是"长三角地区城际轨道交通网规划"中的网络主轴之一,是沪宁通道综合运输体系的重要组成部分,中铁十局集团第四工程公司承担了该线镇江枢纽范围内391孔箱梁的制、提、运、架施工任务,架梁采用JQ900E型架桥机施工技术进行,该技术为国内首次在沪宁城际铁路架设单箱双室无砟轨道整孔箱梁中应用,取得了成功的经验和可观的成果,为以后城际铁路客运专线的施工提供了可靠的依据和技术指标。文章重点介绍JQ900E型架桥机施工特点、工艺及质量控制。

As an axis of the Intereity Rail Transportation Network at theYangtez Delta Area, Shanghai-Nanjing Intercity Railway is also an important channel for the communications between Shanghai and Nanjing. China Railway Tenth Group Fourth Engineering Co. has undertaken the fabricating, lifting, delivering and erecting tasks of 391 box girders at the Zhenjiang Terminal of this line. And it is the first attempt far JQ900E Bridge Erecting Machine to be used in erecting box girders during the construction of Shanghai-Nanjing lntercity Railway in our country. The result has proved successful and satisfactory and it can provide reliable basis and technical support for similar engineering. The article mainly focuses on the construction features, techniques and quality control measures of JQ900E Bridge Erecting Machine.
