Abstract

PROBLEM TO BE SOLVED: To form an incontinuous join part without impairing the advantage of divided bodies to improve the strength of whole structure. SOLUTION: A plurality of concrete archlike wall bodies 10 having a predetermined depth width L are arranged in a row in the direction of depth to constitute a tunnel, the wall body 10 is divided into a small divided body 11 and a large divided body 12 having different peripheral lengths, and the wall bodies 10 adjacent in the direction of depth are arranged in such a way that right and left positions of the small divided body 11 and the large divided body 12 differ from each other. The join parts 13 of the small divided body 11 and the large divided body 12 are alternately positioned to make the join parts 13 incontinuous. Consequently, the strength of the whole structure can be greatly improved when compared with the conventional case where the join parts are continuous.

2. Description of the Related Art Conventionally, as a concrete arch type structure of this type, for example, as shown in FIG. 6, a concrete arch wall 1 having a predetermined depth L is provided in a plurality in the depth direction. It is known to form a tunnel by lining up. In this concrete arched structure, the wall 1 is divided into two parts having the same peripheral length to form a pair of left and right symmetrical divided bodies 1a and 1b.
a and 1b are joined at the divided ends, and the joined wall bodies 1 are arranged in a plurality of rows in the depth direction to form a tunnel. Conventionally, a concrete arched structure as shown in FIG. 7 is also known. This is a concrete arched wall 1 having a predetermined depth L.
Is used. Both base ends of the wall body 1 are integrally fixed to a grounded or buried base body 2 and an upper divided body 1a of an upper portion having a predetermined peripheral length.
And a lower lower divided body 1b. Then, first, the lower divided bodies 1b are arranged in the depth direction and installed, and then, the upper divided body 1a is joined to the lower divided body 1b and provided. When the wall 1 is divided in this way, when the divided bodies 1a and 1b are preliminarily produced in a factory, the size of the divided body 1a and 1b is smaller than that of the whole. This facilitates assembling, and facilitates assembling work. The position of the dividing point (joining portion 3) of the divided body is set at a position where the moment load is small so as not to hinder external force.

In such a conventional concrete arched structure, the dividing points (joining portions 3) of the divided bodies 1a and 1b of the wall 1 do not interfere with external force. However, in this structure, the joint 3 of the divided bodies 1a and 1b is weaker against external force than the integral part, and this joint 3 Because it is located in a straight line in the depth direction and is continuous, weak areas are concentrated, and as a result,
It has been studied to improve the strength of the joint 3. The present invention has been made in view of the above points, and has a concrete arch type structure in which the joints are discontinuous to improve the overall strength without impairing the advantages of the divided body. The purpose is to provide.

In addition, at the joint of the small divided body and the large divided body,
When a groove with a semicircular cross section that forms an insertion hole through which the connection fitting is inserted while the connection part is joined is formed, the joint can be joined with the connection fitting interposed, and the joining becomes strong. Also in this regard, the overall strength can be greatly improved. Further, when an insertion hole through which the connecting metal fitting is inserted is formed at a position in the depth direction of the large divided body and corresponding to the insertion hole formed at the joint portion between the small divided body and the large divided body, the small divided The connection fitting from the joint of the body and the large divided body can be continuously inserted into the insertion hole of the large divided body, so that the joint between the wall bodies can be strengthened, and also in this respect, the overall strength Can be greatly improved.
