Do Metros need Diaphragm Wall Construction?

Metros always run amidst bustling modern cities today, hence the construction of underground stations requires innovative engineering solutions with state of the art equipment to execute them perfectly. Underground metro railway stations are easily two-storied below the ground. And they require to be built with formidable retaining walls that can manage water pressure and take on the weight of the structure above the ground as well as traffic movement. This is where metro diaphragm wall construction plays an important role. They provide the perfect alignment for the structure, act as water barriers and form a formidable foundation for the superstructures.
