摘要
在隧道在施工过程中因措施不到位、控制不严等因素引起的常见缺陷主要有二次衬砌厚度不足,二次衬砌与初期支护之间存在空洞,砼表面存在纵、斜向及网状裂缝等。造成安全隐患,必须及时整治。本文结合具体隧道施工工程,详细介绍了隧道衬砌裂纹处理、渗漏水处理、脱空不密实处理、施工缝错台处理、蜂窝麻面处理、厚度不足处理等,为同类工程施工提供借鉴。
During the construction of the tunnel,common defects caused by factors such as inadequate measures and poor control,such as the insufficient thickness of the secondary lining,the void between the secondary lining and the initial support,the vertical,oblique and reticular cracks on the surface of the concrete.In order to avoid potential safety hazards,the defects must be rectified in time.In this paper,combined with the concrete tunnel construction project,the tunnel lining crack treatment,leakage water treatment,hollowing out uncompacting treatment,construction seam misalignment treatment,honeycomb surface treatment,and insufficient thickness treatment are introduced in detail,which provides reference for similar projects.
