摘要
广州洲头咀隧道E3与E4管段浮运-转体-浮运-寄放施工,是在全程500 m的过程中不使用拖轮,而采用在工程船舶定位后布置卷扬机及牵引点,地锚定位后布置卷扬机及牵引点,用钢缆绞拖牵引管段方式。牵引浮运过程中,管段还必须在主航道的位置定点进行一次90°转体,确保管段在水域河道狭窄的范围内顺利浮运转体。本文介绍了广州洲头咀隧道E3与E4管段浮运前及浮运到寄放位置过程中的施工工艺。
Guangzhou Zhoutouzui tunnel E3 and E4 pipe lfoating-twist-lfoating-park construction is not used in the whole process of 500 tugs in the m, but the location of engineering ship layout winch and traction, traction and post layout to anchor winch, cable winch towing pipe section, traction lfoating process pipe must also be in the main channel of the position of a 90 degree rotation. Ensure that the pipe in the waters of the river narrow range smooth swiveling, this paper will describe the Zhoutouzui tunnel E3 and E4 pipe lfoating and lfoating to the construction process with position in the process of.
