LINING CONSTRUCTION FOR TUNNEL IN SHIELD METHOD AND EQUIPMENT THEREOF

摘要

PURPOSE:To carry out the primary and secondary lining constructions at the same time by execting the primary lining after assembling segments by a segment assembling device and repeating the secondary Lining by pouring concrete into between a mold frame and the segment behind the segment assembling device. CONSTITUTION:Lining construction is executed by installing a segment assembling device 14 behind an excavator 1, and a segment transporting device 16, dolley 17, mold frame transporting vehicle 21, mold frames 24, concrete 25, transporting device 40, and a concrete charger 47 behind the segment assembling device 14. In the process, segments are assembled and the primary lining is performed by the segment assembling device 14, and then concrete 25 is poured into between the mold frame 24 and a segment 13, and then the secondary lining is carried out, and removal is performed in succession from the mold frame 24 after the coagulation of concrete, and concrete 25 is poured again, and the secondary lining is repeated. Accordingly, the primary and secondary linings can be carried out at the same time.
