Optimization of Water Adding System of Shield Machine in Sandy Pebble Mudstone Formation
In order to improve the efficiency of shield tunneling in composite formation,based on the shield sec-tion project from Rulin Road Station to Wujin Station of Chengdu Rail Transit Line 10 Phase II,the water addi-tion system of Herrenkrenk S892 shield tunneling machine in the sand gravel and mudstone composite formation was optimized and reformed.From the aspects of the transformation of the shield water adding system and the control of the water adding,the optimization and transformation of the slag system of the composite sand and peb-ble formation can realize the automatic system control,effectively save the labor and time cost,and provide expe-rience for the construction of similar projects in the future.
