钻孔灌注桩因其适应性、施工简单易操、成本适中、后期质量稳定、承载力大等优点作且设备投入一般不是很大等原因成为最普遍的基础形式,在各类桥梁及民用建筑中得到了广泛的应用。而钻孔灌注桩的施工大部分是在水下进行的,隐蔽性较强,故造成钻孔事故率较高,所以,必须高度重视并严格控制钻孔灌注桩的施工质量,尽量避免发生事故及减少事故造成的损失,以利于工程的顺利进展。
Drilled cast-in-place piles have become the most common basic form due to their adaptability, simple construction, easy operation, moderate cost, stable quality in the later period, large bearing capacity, etc., and the equipment investment is generally not very large, etc., in all types of bridges and civil buildings. It has been widely used. The construction of bored cast-in-place piles is mostly carried out under water, and the concealment is relatively strong, resulting in a high rate of borehole accidents. Therefore, it is necessary to attach great importance to and strictly control the construction quality of bored cast-in-place piles to avoid accidents. And reduce the losses caused by accidents to facilitate the smooth progress of the project.
