Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining for assembling a long lining member which is disposed at a rear portion of a rectangular shield machine for digging a tunnel having a rectangular cross section having a relatively large vertical or horizontal length or width. The present invention relates to a body assembly device.

[0002]

2. Description of the Related Art Conventionally, segments assembled by a segment assembling device at the rear of a shield machine have been used to assemble rectangular or trapezoidal segment pieces having a circular arc cross section.
There are many rectangular segment pieces with a small aspect ratio, and although there are restrictions on the internal equipment, there is a relatively high degree of freedom in handling the segment pieces.

[0003]

By the way, for example, when excavating a tunnel having a long and large diameter and a rectangular cross section,
It is considered that the short side and the long side are divided into a plurality of parts, and these divided parts are excavated by a rectangular shield excavator, and the segments assembled at the rear of the shield excavator are connected to each other to be used as a bulkhead and penetrate the inside. Can be In this case, the tunnel excavated by the rectangular shield machine has the most efficient rectangular cross section with a large aspect ratio.

A lining body assembled in such a tunnel having a rectangular section having a large aspect ratio is composed of a pair of short sides and a pair of long sides, and in particular, divides the long side into a plurality. This makes it easy to assemble even in a narrow tunnel (existing lining), but it takes time to assemble,
Problems are also likely to occur in the waterproof structure and strength. Therefore, when the long side portion is composed of a single unit or a small number of divisions (two divisions or three divisions), there is a problem that it is difficult to handle a long lining member in a narrow existing lining or at the rear part of the shield machine in assembling. there were.
