隧道斜井进洞施工技术要点探讨

Discussion on Key Point of Construction Technology for Tunnel Inclined Shaft Entering Hole

隧道斜井进洞施工容易因地形、地质等因素增加施工难度。文章结合某工程项目实况,对斜井进洞方案进行比选,分析斜井进洞施工准备工作,深入探究斜井进洞施工技术要点。研究结果显示,洞口施工、光面爆破、挑顶施工、超前支护为斜井进洞施工要点,施工单位需严格按照流程施工,重点把控施工质量。

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.
