Earth chamber, thrust device and simultaneous grouting device are designed, so as to study the research methods for the experimental device of simultaneous grouting test platform. A common design method for the earth chamber, thrust device and simultaneous grouting device is summarized on basis of related data in soil mechanics, hydraulic system and shield test platform, considering the conditions of the simultaneous grouting system and the external conditions of the shield machines. The conclusion drawn provides theoretical basis for the establishing of the simultaneous grouting test platform for shield machine in the future.
