[00:00:00]These workers are driving plastic strips into the ground one by one. They need to install 10,000 plastic strips underground in just one hour. So, what exactly are they doing? In fact, this is a method for treating soft soil foundations. It is called vertical drain consolidation. In coastal areas, the underground soil is often soft clay with a very high water content. You cannot build directly on top of it. So, before construction begins, workers use a special installation machine to press plastic drainage boards vertically into the ground. These are not ordinary pieces of plastic. Each one has drainage channels inside and a filter fabric wrapped around the outside. Its job is like filling the soft ground with drainage tubes. Next, workers spread a sand blanket on the surface. Then, they use vacuum pumps to continuously draw air out. This creates pressure that pulls the pore water inside the soft soil upward through the [music] plastic drainage boards. As more water is removed, the foundation becomes denser and stronger.

[00:01:06]So, do you think these plastic strips buried underground could pollute the environment? [music]
