In general, in order to build underground structures such as concrete boxes for sewage pipes, electric communication lines, and subways, digging work is carried out with a depth to the lower side of the ground, and during the digging work, the soils flow down or the ground collapses. In order to prevent this from happening, it is necessary to install a barrier and to carry out the work of blocking the inflow of groundwater from the ground into the construction area.

Although many methods have been conventionally used in the protection work and the installation of the barrier for the barrier, the method of installing the barrier using the sheet pile or the H-beam is common in order to have the barrier and the barrier.

This is to form a wall shape by interconnecting a plurality of sheet piles or H-beams to have the earth wall function for the soil and ground that is located outside the wall.

Among them, an H beam is used to form a soil wall for earthenment. For example, H-beams having H-shaped cross sections are vertically placed in the ground at regular intervals, and sheet piles are not spaced between adjacent H-beams. It is constructed integrally over, and there is what was connected by one wall.

In addition, in order to form the earthenware earth wall of the part requiring high strength, a method of placing H-beams without gaps and connecting them into one wall is used. However, it is not only difficult to place many H-beams without gaps, but also with each other. There was a problem that an error between adjacent H-beams must occur.

In order to overcome this problem, if a separate panel type reinforcement plate (sheet pile or plate type plate) is integrated by welding in order to fill gaps between adjacent H-beams, a separate work is required. In addition to the increase, there was a problem that workability is reduced.

In addition, even when the reinforcing plate is added between the gaps, there was a fear that the coupling site would be damaged when the earth pressure of a pressure larger than usual is transmitted from the outside.

The present invention has been proposed in view of the above-mentioned problems, and its object is to prevent gaps between H beams adjacent to each other, and to improve the durability of earth pressure transmitted from the outside using H beams.

Combining other large diameter H beams with other large diameter H beams on the outer surface of the other end of the small diameter H beams, and then integrating the mutually contacting portions;

Both ends of the small diameter H beam may be coupled to each other by flanges of the large diameter H beams, and may be connected to one wall.

Both sides of the large diameter H-beam and the small diameter H-beam generated after the coupling is further provided with a step of filling the filler in a sealed space.

Another feature of the present invention is a plurality of large diameter H-beams having a structure in which the web is integrally connected between the flanges facing each other and each of which is buried perpendicular to the ground to be spaced at equal intervals;

Both ends of the flanges between the large diameter H-beams are respectively accommodated at both ends, and the outer surface of both flanges are each provided with a plurality of small diameter H-beams are integrally coupled by the coupling means,

A small diameter H beam is sandwiched between the large diameter H beams to form a soil wall for continuous coupling.

The inner surface width between the flanges of the large diameter H-beam is greater than or equal to the width between the flange outer surfaces of the small diameter H-beam.

The coupling means is provided at a position corresponding to each of the flange of the large diameter H-beam and the small diameter H-beam and a plurality of coupling holes having a thread on the inner peripheral surface is formed,
