The present invention relates to an H beam belt used for constructing a temporary mud wall to prevent the collapse of a soil wall at an excavation site for the construction of underground construction structures, and a method of constructing a supportive mud structure using the H beam belt. More specifically, the steel pipes are formed in the longitudinal direction on the inner upper surface and the lower surface of the body of the H-beam strip, inserting a plurality of steel wires inside the steel pipe, the fixing device on one side of the body of the H beam strip And a tensioning device on the other side of the body of the H-beam belt, fixing one side of the plurality of steel wires to a fixing device, mounting the other side to a tensioning device, and tensioning the plurality of steel wires using a tensioner. Thereby transmitting the force to the side wall of the soil wall, thereby causing the H beam belt to be damaged by excess earth pressure that may be generated at the side wall of the soil wall. In addition to preventing them from being dug, they can also reduce the H beam support installed between the H beam belt and the H beam belt by two-thirds, thereby increasing the work efficiency by securing construction space. It relates to a steel pipe and the H-beam girdle provided with a plurality of steel wires, and a construction method of the H beam girder.

In general, a construction method for constructing a temporary mud wall to prevent the collapse of the earth wall at the trench construction site, etc., in order to construct the underground building structure, as shown in Figure 1a to 1b, according to the type of ground to be constructed The H beam pile 1 is inserted into the lower part of the ground at regular intervals and installed.

As described above, when the installation of the H beam pile 1 is completed, the excavation is partially performed, and the earth plate 3 vertically prevents dirt from flowing down between the H beam pile 1 and the H beam pile 1. While installing, the H beam strip 5 is orthogonal to the H beam pile 1, and a plurality of H beam supports 7 are installed between the H beam strip 5 and the H beam strip 5. .

In this case, the method may be changed here, in which the H beam strip 5 is first installed on the H beam pile 1 and the earth plate 3 may be installed between the H beam pile 1 and the H beam pile 1. .

When the above operation is completed, by adjusting the screw jack (9) provided on one side or both sides of the H beam braces (7), and the H beam pile (1) formed integrally with the H beam strip (5) and When the earth plate 3 is brought into close contact with the side of the earth wall, the work process is completed.
