Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeper to be placed in a tunnel in tunnel construction performed by a segment construction method.

[0002]

2. Description of the Related Art In a tunnel construction method using a segment method, a temporary sleeper is placed in a segment of a buried segment tunnel, and a rail for moving a vehicle such as for transporting materials is laid thereon. It has been practiced to arrange treads for the passage of personnel.

[0003] The segments used for tunnel construction are:
Since the outer diameter and thickness are standardized according to the size of the tunnel, if the size of the tunnel constructed by the shield method is known, the segments used will be those of the specified standard. Therefore, it is sufficient to use a sleeper with a rated specification that matches the segment to be used for tunnel construction using that segment, but in actual construction, the position of the reinforcing rib provided on the segment is not necessarily the same depending on the manufacturer. Or, because the position of the joint flange in the circumferential direction of the segment may be displaced, the sleepers of the rated specification can not be laid horizontally because the ribs and the displaced circumferential joint flange are in the way,
In some cases it could not be used. In addition, if the diameter of the segment used is slightly different, the surface position of the sleeper changes in the same sleeper, which may hinder the traveling of the subsequent bogie, etc., and in such a case, the diameter of the segment matches the inner diameter of the segment. Another problem is that another temporary sleeper must be made and used.

However, it is necessary to always form a sleeper according to the difference in the diameter of the segments, the position of the reinforcing ribs and the circumferential seam flange, or to use a sleeper formed in such a manner. This is extremely troublesome in terms of work, and the work efficiency cannot be improved unless a plurality of types of sleepers are prepared in advance.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned prior art temporary sleepers for tunnel construction, and has been described in connection with the tunnel construction of the segment construction method. It is an object of the present invention to provide a sleeper for tunnel construction having a function of being able to be installed correspondingly even if there is a slight difference in the position of the joint flange in the above.

[0006]

SUMMARY OF THE INVENTION A temporary sleeper for tunnel construction according to the present invention, which has been made to solve the above-mentioned problem, is formed by bending a steel strip and extending a support plate obliquely between both ends thereof. A reinforcing plate made of a vertical panel is attached to at least one of the front and rear sides of the triangular member, and a supporting member fitted to the supporting plate so as to sandwich the joint flange of the segment is attached to the left and right positions so as to be adjustable.
