中新网上海8月21日电 (浦帆)记者从中国铁路上海局集团有限公司了解到，20日下午4时左右，在上海市松江区沪苏湖铁路施工现场，经过数小时准备和2小时施工，跨斜塘航道斜拉桥首片钢梁精准吊装到位，为顺利完成全线架梁施工奠定了坚实基础。

Shanghai on August 21st (Pufan)From China Railway Shanghai Bureau Group Co., Ltd. , reporters know that on August 20th round 4 p.m. in Shanghai Songjiang District HuSu Lake railway construction site, after several hours of preparation and 2 hours of construction, the Xietang channel cable-stayed bridge first piece of steel beam precise hoisting in place, which laid a solid foundation for the successful completion of the whole line girder erection construction

沪苏湖铁路东起上海市，途经江苏省苏州市吴江区，沿太湖南岸西至浙江省湖州市，线路全长163.7公里，设计时速350公里，为双线高速铁路。全线共设上海虹桥站、松江南站、练塘站、汾湖站、盛泽站、南浔站、湖州东站、湖州站等8个车站。

The Shanghai-Suzhou-Lake Railway starts from Shanghai in the East, passes through Wujiang District of Suzhou City, Jiangsu Province, and extends along the South Bank of Taihu Lake to Huzhou City, Zhejiang Province in the West. The total length of the railway is 163.7 kilometers, and the design speed is 350 kilometers per hour. It is a two-line high-speed railway. There are 8 stations along the line, including Shanghai Hongqiao Station, Songjiang south station, Liantang station, FenHu station, Shengze station, Nanxun station, Huzhou east station and Huzhou station.

据介绍，沪苏湖铁路跨斜塘航道斜拉桥采用H型主塔，高度95米，主跨260米，横跨斜塘航道，是全线重难点控制性工程。此次架设的钢箱梁梁高3.8米，桁长14米，桁宽29.77米，重达366吨，吊装处所位于航道上方，存在着航道狭窄、封航困难、近塔端节段无法航运吊装等问题，常规吊装方法难以应用，施工难度极大。

According to introduction, the bridge of Shanghai-Suzhou-Lake Railway across Xietang Channel adopts H-shaped main tower, with a height of 95 meters and main span of 260 meters. It crosses Xietang Channel, which is a key and difficult control project of the whole line. The steel box girder erected this time is 3.8 meters high, 14 meters long, 29.77 meters wide and 366 tons in weight. The hoisting place is located above the channel, which has some problems such as narrow channel, difficulty in closing navigation, inability to ship and hoist the section near the tower end, etc. The conventional hoisting method is difficult to apply and the construction is extremely difficult.

为了安全、高效地完成钢梁吊装工作，相关铁路部门在钢梁吊装方法选择上，选取正吊法起吊钢梁，并运用多功能运梁小车调整钢梁落梁摆位，同时结合船体水下抛锚及水上锚桩缆索方式，实现吊装过程的安全稳定。为了便于施工，上海枢纽指挥部还协调施工方向海事部门提出申请，在水上吊装期间斜塘航道采取临时交通管制，最终确保了首片钢梁成功吊装。

In order to complete the steel beam lifting work safely and efficiently, the relevant railway departments select the positive lifting method to lift the steel beam, and use the multi-functional beam transport trolley to adjust the position of the steel beam. At the same time, the safety and stability of the lifting process are realized in combination with the underwater anchoring of the hull and the underwater anchor pile cable method. In order to facilitate the construction, the Shanghai Hub headquarters also coordinated the construction to submit an application to the maritime department. During the water lifting, temporary traffic control was adopted for the inclined pond channel, which finally ensured the successful lifting of the first steel beam.

沪苏湖铁路位于上海市西部、江苏省南部和浙江省北部这一片长三角核心区域，是连通上海、苏州、湖州等长三角重点城市的重要铁路运输通道。建成通车后，将成为长三角地区城际铁路网的骨干线路和环太湖轨道交通圈的重要组成部分，对于助力长三角更高质量一体化发展等具有重要意义。

Shanghai-Suzhou-Lake Railway is located in the core area of the Yangtze River Delta, which is the west of Shanghai, the south of Jiangsu Province and the north of Zhejiang Province. It is an important railway transport channel connecting Shanghai, Suzhou, Huzhou and other key cities in the Yangtze River Delta. After completion and opening to traffic, it will become the backbone line of the inter city railway network in the Yangtze River Delta and an important part of the rail transit circle around the Taihu Lake. It is of great significance to help the integrated development of the Yangtze River Delta with higher quality.
