超大型沉管安装精调系统方案研究与应用
|
摘要
沉管安装着床进行水力压接后,打开沉管封门,通过测量得出沉管尾端偏差,若轴线出现偏差,需要借助一种可靠的技术方案进行精确纠偏。通过对国内外相关沉管隧道轴线调整资料的研究,阐述了沉管管节对接的管内精调法和管外精调法,并对两种技术方案进行对比。结合港珠澳大桥沉管隧道的实际情况,选取应用了管内精调技术方案。
After installing the immersed tube into the bed for water force pressing, the immersed tube seal door is opened, and the deviation of the end of the immersed tube is obtained by measurement. If there is a deviation in the axis, it is necessary to use a reliable technical scheme to accurately correct the deviation. Based on the study of the data of the axis adjustment of relevant immersed tunnel at home and abroad, we expounded the precision method inside and outside the immersed tube joints,and compared the two technical schemes. Combined with the actual situation of immersed tube of the Hongkong-Zhuhai-Macao Bridge, the precision technical programme inside the tube is selected and applied.
