DL/T 5099-2011 (English Version) PDF

Scope: This standard specifies the requirements for construction technology and quality inspection and acceptance of underground engineering excavations for hydraulic structures. This standard is applicable to the drill-and-blast excavation construction of underground engineering structures in large and medium-sized hydropower and water conservancy projects. Other underground engineering construction can be implemented as a reference.
