Non-vibration excavating methods for tunnel or rock slope by cutting and splitting

摘要

The present invention relates to a non-vibration excavating method for a tunnel or bedrock by cutting and splitting, which can be applied to a place in which blasting is not allowed. A predetermined size of stone can be obtained during excavation, cracks can be easily controlled, a drilling rate can be increased. Moreover, required equipment can be simplified and inexpensive, and a discontinuous surface formed on natural bedrock can be used to secure efficiency and simplification of excavating work.
