Laying manner null of temporary roadbed of multiple

摘要

PURPOSE: To lay temporary roadbeds continuously over a long distance in a narrow available space in a short time by installing the temporary roadbed under a beam of a gate type stand, and connecting the temporary roadbed successively to the tip of the preceding temporary roadbed while making the stand travel on temporary rails. ;CONSTITUTION: A gate type stand 3 is composed of a horizontal beam 1 and vertical jacks 2 arranged on both the edges. Temporary rails 6 are arranged on both sides of an expected laying site of a temporary roadbed 4, and crossing rails are laid between the temporary rails 6 and the adjacent expected roadbed installation site. Next, the temporary roadbed 4 is installed in the under surface of a beam 1, and is made to travel on the temporary rails 6 by means of wheels provided under the stand 3 in a condition where the jacks 2 are extended and the stand 3 is raised. 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 preceding roadbed. In succession, the following temporary roadbed 4 is mounted on the crossing rails, and is moved on the crossing rails, and is connected to the tip of the preceding temporary roadbed 4 being laid on adjacent lines. A temporary roadbed 4 for plural number of lines can be laid successively by repeating this process.;COPYRIGHT: (C)1993,JPO&Japio
