WHAT WE DO

   

   

Caverns

The creation of underground space is the most favorable method to improve the environmental quality and support sustainable development; however it should be properly planned by specialists with substantial experience of non-renewable resources. ESCO’s engineers have considerable experience having participated in diverse underground space development projects such as an underground wine storage cavern, silo type nuclear waste repository cavern, etc.

 

Caverns

The project layout shown above is the nuclear waste repository cavern for low and medium level wastes. It consists of six silos, each 50m deep and 27m in diameter constructed successfully with the design provided by ESCO. Challenging technical issues were the selection of adequate excavation methods and support systems and their verifications. In particular, not all silos were aligned within similar ground conditions even though they were located at relatively close spacing.
