摘要
针对容易出现的空洞现象,从分析原因入手,紧密结合水泥浆液的试验数据和施工具体情况,采用掺加减水剂和膨胀剂的方法,选出合理的孔道压浆配合比,很好地解决了后张梁孔道压浆空洞现象的发生。
On the void which frequently appears, this paper begins with the analysis of reasons, combines the cement seriflux experimental data with detailed construction conditions closely, taking the method of adding plasticizer and expansion agent to make out the proper duct grouting mixture rate, which solves the void in the duct grouting with post-tensioning beam well.
