ShenzhenZhongshan
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
ShenzhenZhongshan link, this process can be used for
reference in similar projects.
