摘要
某工程桩采用自平衡法进行抗拔承载力检测,因荷载箱下部加强层混凝土浇捣不密实,无法提供试验所需的反力,试验无法进行,后通过对缺陷部位进行高压旋喷灌浆加固,加固后再次进行试验,试验顺利完成。
Lifting capacity test of a pile using self balanced method can＇t be accomplished because of concrete defect of lower pile under the load cell. To solve the problem, the measurement was made to strength the pile using high-pressure whirl-spray grouting technique and the test was accomplised.
