| Abstract: | In this paper, the test has been done to select the appliciable plasticizer, the means that the bentonite being mixed into mortar has been taken, and the proportioning of mortar has been optimized. The working performance of synchronous grouting by shield method of cement mortar has been improved, and the aim to avoid the jam in the grouting and make the pressure of the grouting at the range of being set up has been achieved. The good results of grouting has been obtained by the excellent performance of mortar. |
