钻孔灌注桩越来越多的被工程中采用,但是其工程质量控制的直观性差,施工工艺相对复杂,易出现孔底沉渣大,桩身夹渣、缩颈、断桩、离析等缺陷,因此,在施工中采取多种措施严格控制工程桩的成孔、钢筋笼的安放、混凝土的浇筑等质量尤为重要。 Drilled cast-in-place piles are increasingly used in construction projects, but the intuitive quality control of their projects is poor, and the construction process is relatively complex. It is prone to defects such as large sediments at the bottom of the hole, slag inclusions, necking, broken piles, and segregation. Therefore, it is particularly important to take various measures in construction to strictly control the quality of the holes in the construction piles, the placement of reinforcing cages, and the pouring of concrete.
