就钻(冲)孔桩的施工工艺而言,钻(冲)孔桩的施工并不太复杂。但是,近年来随着钻(冲)孔桩的广泛应用,施工单位的素质出现参差不齐,一些施工单位由于对泥浆制备以及水下混凝土等施工工艺中的关键环节控制不严,从而使钻(冲)孔桩工程造成一定的施工困难或程度不同的质量事故。常见的质量问题主要有:塌孔、梅花孔(桩孔局部缩颈)、桩孔倾斜(垂直度不足)、桩钢筋笼
As far as the construction technology for drilling (punched) piles is concerned, the construction of drilled (punched) piles is not very complicated. However, in recent years, with the wide application of drilling (punched) piles, the quality of construction units has been uneven, and some construction units have made drilling difficult due to loose control of key links in mud preparation and underwater concrete construction processes. (Punch) hole pile engineering causes certain construction difficulties or quality accidents with different degrees. The common quality problems are: collapse holes, plum blossom holes (local necking of pile holes), pile hole inclination (insufficient verticality), pile reinforcement cage
