The difficulty of tunnel inclined shaft entering hole construction is easy to be increased due to factors such as terrain,geology.Based on the actual situation of an engineering project,this paper compares and selects the inclined shaft entering hole schemes,analyzes the preparation work of inclined shaft entering hole construction,and deeply explores the key points of inclined shaft entering hole construction technology.The research results show that the hole entrance construction,smooth blasting,roof construction,and the advance support are the key points of the inclined shaft entering hole construction.The construction unit needs to strictly follow the process to carry out construction and focus on controlling the construction quality.
