<p>The present invention relates to a ground structure using steel piles for stably constructing various kinds of structures such as bridges and retaining walls on the ground, buildings on the water and housings, wherein steel piles having resistance to vibration are buried underground as shafts. A bridge structure according to an embodiment of the present invention includes: a steel pile fixed with at least two or more ribs in the radial direction outside the front end portion of a steel pipe, which is in the hollow cylindrical shape, and an extension plate in the doughnut shape with a diameter larger than the steel pipe on the bottom surfaces of the ribs; a main girder supporting beam stacked on top of the steel pile; a composite beam stacked on the main girder supporting beam and formed of a first beam, a second beam stacked on top of the first beam, and overlapping connection plates overlapping the both lower end portions of the first beam and the both upper end portions of the second beam; and a deck plate stacked on top of the composite beam. The steel pile is fixed and supported by concrete, which is mixed with a corrosion inhibiting admixture, in the bore hole in the ground. The composite beam is coupled by bolts which penetrate the first beam, the second beam and the overlapping connection plates.</p> |
