摘要
某工程混凝土灌注桩桩基施工中,遇桩底虚土厚度大,影响桩的承载力,而采用桩端压力灌浆的施工工艺解决了这一难题,实践证明,该工艺在工程中使用效果良好,是处理混凝土灌注桩桩底虚土的有效方法。
The construction of the pile foundation of a project encountered a thick layer of loose soil at the pile tip that affected the load beating capacity of the pile. This dfficulty was resolved by applying the construction technology of pile tip pressure grouting. Practice shows that this technology has a good application effect in engineering and is an effective method for the treatment of loose soil at the tip of driven cast-inplace pile.
