pile shaft quality

These factors, which include slurrys preparation, circulation, depuration and so on, would influence drilling speed, bore quality, exertion of pile shaft resistance and base resistance.

泥浆制备、循环、净化等因素的好坏直接影响到钻进速度和成孔质量、桩侧摩阻力及桩端阻力的发挥。

Since the excavated hole is also the form of the pile shaft, its quality control plays an important role of the whole installation.

挖孔桩的孔筒是桩的模具，其成孔质量检验是桩基施工的重要组成部分。

The construction of drilled hole with shaft wall protection by drilling mud belongs to the concealed work, the pile quality influences directly the superstructure security and the building subsidence.

泥浆护壁钻孔灌注桩施工属于隐蔽工程，成桩质量的好坏直接影响上层结构的安全和建筑物的沉降。
