摘要
More particularly, the present invention relates to an H-file disposed at a predetermined distance from a rock bed or a designed depth to a supporting bed. And a steel plate member embedded in the ground between the H files to stabilize the ground and perform an order function, wherein one side of the angle member having a trailer section is coupled to both sides of the web of the H file, The other side surface of the angle member is parallel to the flange of the H file so that a space portion is formed between the flange and the web and the angle member, a straight iron plate member is coupled to the other side space portion of the angle member, A plurality of first groove portions are formed in the direction of the space of the straight iron plate member, the steel plate members are straightly formed by a hot-rolled steel plate, the both end portions are provided with a second groove portion, The groove portion is filled with a water expandable index material so that the volume of the water expandable index material expands due to contact with water, Parts provides a method using gasiseol retaining retaining structure, and this hot-rolled steel sheet-order continuous wall, characterized in that to ensure that the binding to the H files the steel member by a Sikkim filled. According to the present invention, when the steel sheet is inserted into the retaining structure, the gap between the flange and the angle member of the H file can be easily adjusted to various kinds of steel sheet thicknesses, It is possible to positively cope with the steel sheet of the steel plate and to take up the clearance space between the steel plate and the H file relatively easily. Therefore, even if the vertical degree of the H file or the steel plate is slightly lowered, It is possible to prevent the problem that the work is stopped and the construction can be carried out by varying the thickness of the steel sheet regardless of the kind of the soil such as sand, clay, and soft ground layer. Further, since the clearance between the steel sheet and the H file can be completely filled with the water expansive index material as time elapses after the installation of the earth retaining structure, it is possible to maximize the order effect and by separately constructing the angle member and the straight iron plate member, The size, thickness, and earth pressure of the flat iron plate member can be variously set in accordance with the size of the flat iron plate member or the thickness of the flat plate member. Therefore, it is possible to simultaneously increase the supporting force, order effect, stability, workability, material recyclability, It is effective.
