基础工程是桥梁工程的重要组成部分,钻孔灌注桩又是桥梁基础中常见的类型,近年来在高速公路的桥梁基础中应用尤为广泛。在施工中,由于影响钻孔灌注桩质量的因素很多,而水下混凝土灌注的施工方法也是重要的因素之一。因此,必须在水下混凝土灌注的施工方法上严格把关,确保钻孔灌注桩的工程质量。 Basic engineering is an important part of bridge engineering. Bored piles are common types in bridge foundation. In recent years, they have been widely used in the bridge foundation of expressway. In construction, due to the many factors that affect the quality of bored piles, the construction method of underwater concrete pouring is also one of the important factors. Therefore, we must strictly control the construction method of underwater concrete pouring to ensure the quality of the bored pile engineering.
