Temporary rails 6 are arranged on both sides of an expected laying site of a temporary roadbed 4. Next, the temporary roadbed 4 is installed in the under surface of beam 1, and the jacks 2 are extended, and the stand 3 is raised, and the stand 3 is made to travel on the temporary rails 6 by means of the wheels 5 in this condition. Next, it is stopped in a prescribed position, and the stand 3 is lowered, and the temporary roadbed 4 is connected to the tip of the previously laid temporary roadbed 4, and afterwards, the connection between the temporary roadbed 4 and the stand 3 is released.;COPYRIGHT: (C)1993,JPO&Japio
