摘要

深中通道采用水下整体推出式最终接头新技术，为确保后焊接工序处于无水环境，在推出段及扩大段之间设置“M止水带+充气式止水带”作为后焊段施工期临时止水措施；其中充气式止水带是第2道止水措施，起到至关重要的作用。最终接头充气式止水带安装空间狭窄，安装难度大，因此采用定制工装件整体吊装定位安装的新工艺。该工艺解决了狭窄空间内充气式止水带的超长构件安装难题，提高了安装效率，确保了安装质量。通过深中通道最终接头现场实践，该工艺可在类似工程中参考应用。

Abstract

ShenzhenZhongshan link adopts a new technology of underwater integrated push out final joint. To ensure that the welding process is in a waterless environment, an "M water stop + inflatable water stop" is installed between the push out section and the expansion section as a temporary water stop measure during the construction period of the welding section. The inflatable water stop is the second water stop measure and plays a crucial role. The installation space of the final joint inflatable water stop is narrow, and the installation difficulty is high. The inflatable water stop adopts a new method of lifting and positioning the installation with customized tooling parts, and the overall lifting and positioning installation is carried out with customized tooling parts. The process solved the problem of installing ultra long components of inflatable water stop in narrow spaces, improved installation efficiency, and ensured installation quality. Through the field practice of the final joint of ShenzhenZhongshan link, this process can be used for reference in similar projects.
