Hereinafter, a method of constructing a corrugated steel sheet structure and a preferred embodiment of the structure according to the present invention will be described in detail with reference to the accompanying drawings.

The corrugated steel sheet structure according to the present invention forms a bridge, a tunnel, an underground cavity, a culvert channel and the like, and FIG. 1 shows an embodiment of the corrugated steel sheet structure. And Figure 2 is a block diagram showing a construction method for constructing a corrugated steel sheet structure.

Referring to the drawings, the construction method of the corrugated steel sheet structure is a trench construction step 110 for digging for foundation work at the place where the corrugated steel sheet structure is installed, and parallel to each other using a concrete steel structure in the area where the foundation trench is completed Base surface construction step 120 for constructing a base surface having one base (11, 12). Here, the bases 11 and 12 are provided with channels 13 and 14 for supporting the corrugated steel plates 21 at the lowermost end of the structure in the longitudinal direction, and the channels 13 and 14 are concrete structures. The bases 11 and 12 may be supported by anchor bolts or embedded in the bases 11 and 12. The bases 11 and 12 supporting the lowermost corrugated steel plates 21 are not limited to the above-described embodiments, and may have any structure that can support the end of the arcuate structure 20. have.

When the construction of the base surface having the base (11, 12) as described above is completed corrugated steel sheet assembly step 130 to form the arcuate structure 20 by assembling the corrugated steel sheet 21 from each base 12 and The reinforcing means installation step 140 of installing the reinforcing means 30 to prevent the arched structure from being deformed by external pressure is performed on the arcuate structure 20.
In the corrugated steel sheet assembling step 130, corrugated steel sheets 21 are interconnected by using high tension bolts. The corrugated steel sheets 21 are each bent at a predetermined curvature according to the shape of the arcuate structure 20. Has a structure. The corrugated steel sheets 21 constituting the arcuate structure 20 may have a corrugated shape, but are not limited thereto, and may be formed in various forms according to structural strength and characteristics of the structure.

When the arcuate structure 20 is completed by the assembling of the corrugated steel sheet 130 or the corrugated steel sheet, the reinforcing means 30 for improving the structural strength of the arcuate structure 20 against external pressure is provided. Reinforcing means installation step 140 is performed, the reinforcing means installation step 140 is a reinforcement channel installation step 141 for installing the reinforcement channels 31 in the longitudinal direction on the outer peripheral surface of the corrugated steel sheet structure 20 and And a first rope installation step 142 connecting the bases 11 and 12 and the at least one reinforcement channel 31 of the corrugated steel sheet structure 20 to the rope 32, and the one reinforcement channel 31. Using the second rope installation step 143 for connecting at least one or more reinforcement channel 31 to the rope 33 and the turnbuckles 34, 35 installed on the ropes 32, 33 It comprises a tensile force adjustment step 144 to adjust the tensile force of each rope (32) (33). The reinforcing channel 31 is installed in the longitudinal direction of the arcuate structure 20 so that the uniform tensile force of the ropes is applied to each corrugated steel plate 21 in the direction in which the reinforcing channel 31 is installed. The reinforcing channel 31 is provided with a hook or hook for connecting the ends of the ropes 32 and 33.
In the reinforcing means installation step 140, the reinforcing means 30 is not limited by the above-described embodiment, the backfill construction 150 to be described later using a separate structure inside the arcuate structure 20 The arch structure may be formed of rods installed in a direction in which the rope is installed so as to prevent deformation of the arch structure to be deformed by the earth pressure of the earth and sand 100 being backfilled.

When the reinforcing means installation step 140 is completed, the backfill construction step 150 for filling the soil back on the side and the upper portion of the arch structure is performed. The backfilling construction is preferably to prevent the subsidence or unequal sedimentation after construction and backfilled with the earth and sand on both sides of the arch structure.

When the backfill construction is completed as described above, the step of removing the reinforcement means for removing the reinforcement means 30 for connecting the base (11) 12 and the reinforcement channel 31.

The reinforcing means removing step 150 may be performed at the time when the backfilling construction is completed or may be removed after the backfilling part is sufficiently settled and compacted.

As described above, the construction method of the corrugated steel sheet structure and the corrugated steel sheet structure using the same can easily prevent the construction of the arcuate structure during construction. In particular, it is possible to prevent the arched structure from being crushed or deformed due to the unevenness of the earth pressure applied from both sides of the arched structure at the time of refilling the soil.
