Abstract

Ground conditioning test platform, which is a basic facility needed to develop ground conditioning agents used in tunneling by EPB shield machines, must have perfect control system and perfect test analysis capability. In the paper, the functional requirements of the ground conditioning test platform are presented, the application of the synchronic propulsion technology, the screw conveying technology and the foam generating technology in the hydraulic systems of the propulsion system, the screw conveying system and the foam generating system are analyzed, the major parameters of the hydraulic systems are calculated, the working principle of each hydraulic system is described in detail and the control strategy of the hydraulic systems is analyzed. The practice shows that the hydraulic systems designed can meet the control requirements of the test platform. 

Key words： shield machine; ground conditioning; test platform; hydraulic system; synchronic propulsion system; screw conveying system; foam generating system
