In the process of shield construction in urban rail transit construction, shield muck or mud with more water content may be produced. The particle size of shield muck is relatively small and in the flow plastic state, so there must be many difficulties in transportation. It is time-consuming and laborious to clean up the overflow of slurry in the process of residue transportation, and the cost of transportation and disposal is high. At present, engineers have put forward higher requirements for solving the problem of shield muck slurry separation technology. Taking the shield tunnel project between two stations of Chongqing Rail Transit Line 18 as an example, combined with the on-site soil conditions, through the investigation and analysis of the existing mud-water separation methods, the slag-soil-slurry separation equipment suitable for the site is selected and designed, so as to solve the problems of difficult transportation and abandonment of shield slag and environmental protection. At the same time, it can also provide some reference for the treatment of slag-soil slurry under this kind of characteristics in the future.
