本文主要介绍了在喷射混凝土拌合物中二次添加减水剂,以解决TBM施工过程中使用喷射混凝土因运输距离远、转运环节多造成的混凝土拌合物性能(坍落度损失过大)不能满足施工要求的技术问题。
In this paper, the secondary superplasticizer is added to the shotcrete mixture to deal with the concrete mixture performance (the loss of slump is too large) caused by the long distance transportation and the transportation links of the shotcrete used in the TBM construction process, Can not meet the construction requirements of the technical issues.
