灌注桩是水利及桥梁建筑工程中常见的一种基础结构形式,灌注桩的施工工艺可分为测量放线、造孔、清孔、钢筋制作与安装、灌注混凝土等工艺。灌注桩的施工质量对工程的安全起着很大的作用,施工中一旦发生质量事故,事后补救措施难度很大。 Cast-in-place piles are common forms of infrastructures in water conservancy and bridge construction. The construction process of cast-in-place piles can be divided into measuring pay-off, making holes, clearing holes, making and installing rebar, pouring concrete and other processes. The quality of construction of bored pile plays a great role in the safety of the project. Once a quality accident occurs during construction, it is very difficult to remedy the situation afterwards.
