北江某船闸工程深基坑边坡支护施工技术研究

Research on Slope Support Construction Technology of Deep Foundation Pit of a Ship Lock Project in Beijiang

文章以北江某船闸深基坑边坡支护工程为例,介绍了挂网喷射混凝土、灌注桩及桩前混凝土挡板的边坡支护方式。在施工过程中,该边坡支护方式有效地保证了深基坑边坡的稳定性,确保了基坑施工期间的作业安全。此船闸基坑边坡支护施工经验可为类似工程边坡施工提供参考依据。

Taking a deep foundation pit slope support project of a ship lock in Beijiang as an example,this paper introduces the slope support methods of hanging net shotcrete,cast-in-place pile and concrete baffle in front of the pile.In the construction process,the slope support method effectively ensures the stability of the deep foundation pit slope and the safety of the operation during the foundation pit construction.The construction experience of foundation pit slope support of this ship lock can provide references for the slope construction of similar projects.
