Secondly, when the outer corrugated steel plate 110 and the inner corrugated steel plate 120 are coupled to each other, the inner side of the outer corrugated steel plate 110 extending downward by the stepped portion 130 is coupled with the anchor 300 (Since the inner corrugated steel plate 120 and the anchor 300 do not need to be joined separately), an excellent structure and an efficient structure can be obtained.

The structure in which the inner protruding portion 111 of the outer corrugated steel plate 110 and the outer protruding portion 121 of the inner corrugated steel plate 120 are mutually coupled in the combined structure of the two corrugated steel plates 110 and 120 is considered to maximize the reinforcing effect (Figs. 4 and 5).

The anchor 300 has a structure of a side anchor 310 whose one end is embedded in the protruding wall body 210 and the other end is coupled to the inner side protruding portion 111 of the outer corrugated steel plate 110 in a bolt- The above-mentioned effect can be sufficiently obtained (Fig. 6).

The lower anchor 320 further includes a lower anchor 320 having one end embedded in the main wall 220 and the other end coupled to a lower portion of the outer corrugated steel plate 110, The combined structure of the anchors 310 and 320, the reinforcing member 400, and the outer corrugated steel plate 110 can provide a strong and efficient coupling structure, Is added.

The other ends of the anchors 310 and 320 can be coupled through the through holes 411 of the side plate portion 410 of the reinforcing member 400 and the through holes 421 of the lower plate portion 420 by a bolt- .

When a part of the lower end of the corrugated steel plate 120 is installed to be embedded in the protruding wall body 210 when the concrete is poured, a more stable coupling structure can be achieved.

Hereinafter, the corrugated steel plate coupling structure (A) according to the present invention will be described.

The outer corrugated steel plate 110 and the inner corrugated steel plate 120 are combined to form the corrugated steel plate assembly so that the step 130 is formed.

A mold and a steel assembly (201) for the formation of the wall (200) is installed.

One end of the anchor 300 is coupled to the reinforcing assembly 201 and the other end of the anchor 300 is coupled to the external corrugated steel plate 110.

More specifically, one end of the side anchor 310 is coupled to the reinforcing assembly 201, and the other end of the side anchor 310 is connected to the side plate portion 410 of the reinforcing member 400 and the inner side projection portion 410 of the outer corrugated steel plate 110. [ One end of the lower anchor 320 is coupled to the reinforcing assembly 201 and the other end of the lower anchor 320 is coupled to the lower plate 420 of the reinforcing member 400. [

The reinforcing bar assembly 201 is buried and the wall body 200 is formed by pouring concrete into the mold so as to be in surface contact with the inner surface of the reinforcing member 400.

In this case, since the wall 200 can be formed by placing the concrete in a state where the reinforcing bar assembly 201, the anchor 300, the reinforcing member 400, and the external corrugated steel plate 110 are assembled firmly, A strong and stable reinforcement structure as a whole can be obtained.

As described above, the tunnel structure according to the present invention includes both side walls 200; An arcuate lid 100 installed to cover the upper portions of both side walls 200 by corrugated steel plates; And a corrugated steel plate joining structure (A) formed at a joining portion of the wall 200 and the arcuate lid 100.

The arcuate lid 100 includes a side reinforcing portion 100a formed by a combination of an external corrugated steel plate 110 and an internal corrugated steel plate 120 constituting the corrugated steel plate coupling structure A; And a ceiling portion (100b) formed by the external corrugated steel plate (110) in an area between side reinforcing portions (100a) on both sides.

That is, instead of applying the dual steel plate structure by the combination of the external corrugated steel plate 110 and the internal corrugated steel plate 120 to the entire area of the arcuate lid 100, stress concentration due to wind loads, seismic loads, By applying the above double steel plate structure only to the reinforcing portion 100a, excellent structural stability can be obtained while achieving economic efficiency.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims.
