随着建筑物层数的逐步提高,近几年来,钢筋混凝土预制桩的用量日益增多。预制钢筋混凝土桩在施工过程中,质量问题也时有发生,特别是桩顶打碎,造成桩报废,既影响工程进度,又使经济遭受损失。另外,将桩打歪也常有发生。本文根据施工实践和调查资料,对桩顶打碎问题、偏桩问题进行综合分析。 With the gradual increase of the number of buildings, the amount of reinforced concrete precast piles has increased in recent years. Precast reinforced concrete piles in the construction process, quality problems occur from time to time, especially broken pile top, resulting in pile scrap, both affect the progress of the project, but also make the economy suffer losses. In addition, pile snoring often occurs. Based on the construction practice and survey data, this paper comprehensively analyzes the problems of broken piles and partial piles.
