Abstract:

In recent years, great progress has been made in waterproofing and drainage technologies. In this paper, the application and development of the design and construction of waterproofing and drainage and durability of concrete structure of underground works, maintaining of operating underground works and investigation and treating of disease are presented, so as to further optimize the waterproofing and drainage technology and the durability design, and to improve the construction technologies and waterproofing quality of underground works. The authors hope that the waterproofing and drainage technologies be further improved.
