摘要
对某2个桥梁工程大型支座后灌浆模拟试验进行介绍,工程一采用自配高性能水泥砂浆进行封闭循环灌浆施工工艺,工程二采用水泥浆收缩补偿自流平砂浆敞开式循环灌注施工工艺,试验后实测填充密实效果达到预期目标。对类似大型支座后灌浆工程具有一定的指导意义。
This article introduces the post-grouting simulation test of large-scale bearing of two bridge projects.The first project adopts the self-prepared high-perfonnance cement mortar for closed circulation grouting construction technology,and the second project adopts the cement slurry shrinkage compensation self-leveling mortar open circulation grouting construction technology.After the test,the measured filling and compaction eflFect reached the expected goal.It has certain guiding significance for the grouting project behind the large-scale bearing.
