摘要
钻孔灌注桩桩端后压浆技术具有提高单桩承载力、保证桩基施工质量、节约造价等优点,适用于持力层为砂砾石或碎(卵)石土层的钻孔灌注桩工程。通过工程实例,对桩端后压浆技术的加固机理、施工工艺及施工过程中出现问题的处理方法作了详细阐述。
Bored cast-in-place pile post grouting can promote the bearing capacity of single pile, guarantee the pile construction quality and save construction cost, which fit to bored cast-in-place pile engineering in bearing layers of sandy gravel and gravel soil. With the field case, the paper detailed the reinforcement mechanism, construction technology and treatment measures for construction difficulties.
