钻孔灌注桩因其承载力大、造价低、适用于各种土质、能制成较大直径和各种长度桩等优点,而在建筑工程中应用广泛。由于钻孔灌注桩施工工艺的特殊性和复杂性,施工的全过程技术和质量控制就显得十分重要。本文作者根据自身多年来的实践施工经验,就钻孔灌注桩施工过程中技术操作要点和质量控制措施作以阐述,以供同行参考。
Bored pile because of its large carrying capacity, low cost, suitable for all kinds of soil, can be made of large diameter and various lengths of pile, etc., but widely used in construction. Due to the particularity and complexity of the bored pile construction process, the whole process of construction technology and quality control is very important. The author of this article, according to his years of practical experience in construction practice, elaborates on the technical operation points and quality control measures during the construction of bored pile for the reference of peers.
