软体排缩排原因分析及控制
|
摘要
针对混凝土联锁块和软体排施工工艺的特点,分析软体排在沉排过程中的排体收缩原因,提出利用混凝土构件控制软体排收缩的解决方法。沉排对比试验结果表明,放置混凝土构件的软体排具有良好的排体收缩控制功能。
According to the characteristics of flexible mattress of concrete interlocking blocks and the construction technology of flexible mattress, we analyzed the shrinkage causes of flexible mattress during sinking, and proposed a method which uses concrete members control shrinkage of flexible mattress. The comparison test for sinking the flexible mattress shows that the flexible mattress with concrete members has good shrinkage and control functions.
