隧道初砌渗水掉块等缺陷整治施工技术

On the Construction Technology of the Defect Improvement of Water Seepage and Block Falling in Tunnel Lining

隧道衬砌渗水已成为影响运营隧道结构强度和稳定的关键因素。为了能在运营隧道的日常管理与维护过程中有效预防运营隧道衬砌渗水的发生,从衬砌边墙渗水及综合洞室渗水、衬砌施工缝裂纹掉块方面进行分析,并提出有效的整治措施,为同类工程施工提供借鉴。

The seepage of tunnel lining has become a key factor affecting the structure strength and stability of the tunnel operation. In order to effectively prevent the occurrence of water seepage in the tunnel lining during the daily management and maintenance of the tunnel, this study analyzes the seepage of the lining side wall, the chamber seepage, and the block falling from the lining construction, and puts forward the effective measures for the same kind of engineering construction.
