近年来,旋挖钻孔桩施工以其施工速度快、占地少、适应强、相邻干扰小、承载力大等优点,在堤防除险加固工程中被广泛应用。由于桩基施工从钻孔到完成混凝土浇筑大多都是在水下进行,具有极强的隐蔽性,受到施工中各道环节与各种因素的影响,施工质量波动较大。文章就如何进行旋挖桩施工质量控制和采取有效防治措施,确保成桩质量进行分析与阐述。
In recent years, rotary drilling bored pile construction with its construction speed, less land, adaptable, adjacent interference, bearing capacity and other advantages, in the dike reinforcement project has been widely used. As the construction of pile foundations from drilling to completion of concrete pouring are mostly carried out under water, with strong concealment, affected by all aspects of construction and various factors, construction quality fluctuations. The article on how to carry out the rotary pile construction quality control and take effective prevention measures to ensure the quality of pile into analysis and elaboration.
