通过改进后压浆施工工艺提高钢筋混凝土灌注桩的承载力

Increasing the Bearing Capacity of Reinforced Concrete Piles through Improving Post-grouting Construction Technique

钢筋混凝土灌注桩后压浆技术能有效提高承载力,通过对桩端和桩侧的工艺改进和优化,确保注浆效果,增加桩端和桩侧的承载力,从而提高单桩承载力、减小桩身位移,进而达到设计承载力的要求。

The Post-grouting technique for the construction of reinforced concrete piles can effectively increase the bearing capacity of the piles, and the technical improvement and optimization of the pile end and pile side can guarantee the grouting effect and increase the bearing and reducing pile body＇ s displacement, and capacity of pile end and pile side, thus satisfying the requirement of designed increasing single pile＇ s bearing capacity bearing caoacitv.
