Abstract: Based on the background information of the Pearl River Delta Physical Geography, the negative influence of soil and water quality characteristics on underground engineering materials were mainly discussed. And for the actual situation of environmental pollution, it recommended several materials which have better protection functions. Taking the underground fire hose renovation project in a middle schoolin Guangzhou as an example, the new technology Erbusitu was introduced. Finally, the experience points were summed up which can be reference for similar projects.
