Description of the Related Art Conventionally, as a concrete arch type structure of this kind, for example, as shown in FIG. 6, a plurality of concrete arch-shaped wall bodies 1 having a predetermined depth width L are arranged in the depth direction. It is known that tunnels are arranged in a row. In this concrete arch-shaped structure, the wall 1 is divided into two with the same circumferential length to form a pair of left and right symmetrical divided bodies 1a and 1b.
While a and 1b are joined at the division end, a plurality of rows of the joined wall bodies 1 are provided in the depth direction to form a tunnel. Conventionally, a concrete arch-shaped structure as shown in FIG. 7 is also known. This is a concrete arch-shaped wall body 1 having a predetermined depth width L.
Is used. Both base end portions of the wall body 1 are integrally fixed to the base body 2 which is grounded or buried, and the upper divided body 1a of the upper portion having a predetermined circumferential length.
And a lower lower divided body 1b. Then, the lower divided body 1b is installed in a row in the depth direction first, and then the upper divided body 1a is joined to the lower divided body 1b. The partitioning of the wall body 1 in this way is smaller than the whole when the partition bodies 1a and 1b are factory-produced in advance, so that the molding is easy and the manufacturing efficiency is good, and on the site. Is easy to assemble, so that the assembling is easy and the assembling workability is improved. The position of the dividing point (joint portion 3) of the divided body is set to a place where the moment load is small so as not to hinder the external force.

However, in this structure, the joint portion 3 of the divided bodies 1a and 1b is weaker than the integral portion with respect to an external force. Since they are positioned in a straight line in the depth direction and are continuous, weak areas are concentrated, and as a result,
Research has been conducted to improve the strength of the joint 3. The present invention has been made in view of the above points, and a concrete arch-shaped structure that improves the overall strength by making the joints discontinuous without impairing the advantages of the divided bodies. The purpose is to provide.

向上させられる。A concrete arch-shaped structure of the present invention for solving the above-mentioned problems has a plurality of rows of concrete arch-shaped wall bodies having a predetermined depth width in the depth direction. In a concrete arch-shaped structure that is installed to form a tunnel, the wall body is divided into a small division body and a large division body having different circumferential lengths, and the adjacent wall bodies in the depth direction are mutually divided into the small division bodies. And the large divided body is arranged so that the left and right positions are different. As a result, the joints of the small divisions and the large divisions are alternately positioned, and the joints become discontinuous. Therefore, the strength of the whole can be significantly improved as compared with the case where the joining portion is continuous as in the conventional case.
