摘要
当前,地下连续墙已越来越多地应用于深基坑的围护结构,利用机械开挖成槽,通过静态泥浆护壁,清底刷壁置换除渣,灌注水下混凝土成墙。本文阐述了在不利地质条件下进行地下连续墙成槽的施工工艺要点,通过对各施工工艺的细化分解,有效保证成槽施工质量,为地下连续墙在复杂周围环境和不利地质条件下的成槽施工提供借鉴。
At present,the diaphragm wall has been increasingly applied to the retaining structure of deep foundation pit,using mechanical excavation into groove,through the static mud wall protection,clean the bottom wall replace?ment slag removal,pouring underwater concrete wall.This paper described the key points of the construction process of underground continuous wall grooving under unfavorable geological conditions,through the refinement of each con?struction process decomposition,effectively guaranteed the trench construction quality,to provide a reference for the construction of underground continuous wall into the groove in the complex surrounding environment and unfavorable geological conditions.
