Special Construction Technology on Entrance and Exit Excavation Engineering of Metro Station
This paper aims to study the key techniques in concealed excavation engineering for subway station entrances,systematically discussing issues related to engineering geology,construction process,safety measures,and monitoring.The mining method is adopted as the main construction approach,strictly following the eighteen-character guideline as"advanced pipe-shed support,strict grouting,short excavation,strong support,quick closure,and frequent measurement"to ensure construction efficiency and safety.During the construction process,detailed geological surveys were conducted to understand the complexities of underground engineering,and corresponding construction technical measures were formulated.Additionally,modern monitoring technology was employed to provide real-time monitoring of the entire construction process,allowing for timely adjustments to construction parameters to ensure quality and safety.Through specific engineering cases,the feasibility and effectiveness of the adopted technical solutions were verified,and suggestions for further optimization of construction techniques were proposed.
