The present invention relates to a welded H-shaped steel sheet pile and a unitary composite order wall using the same. Specifically, the present invention, when constructing a wall used for the use of water curtains in civil engineering or building construction, has a H-shaped cross-section and combined with a steel sheet pile of the conventional U-shaped cross-section to function as a sheet pile It can be easily and firmly constructed, but also functions as a pile to serve as a foundation for various structures, as well as to increase the rigidity of the wall. The present invention relates to a welded H-beam pile of a new structure suitable for use in the construction of a wall that can be used for construction, and an integral composite ordered wall constructed using the same.

The use of steel sheet piles is increasing for water barriers and the order of groundwater. 1 shows a schematic perspective view of a wall formed by a conventional steel sheet pile 100, and FIG. 2 shows a schematic plan view of the wall shown in FIG.

Conventional steel sheet pile 100 is made of a steel plate, as is already known, as shown in Figure 2, when viewed in plan view, the steel plate is U-shaped bent and the end of the annular connecting end bent in a ring shape at the bent end 101 is formed, the neighboring steel sheet pile 100 is arranged in a different direction from each other while the annular connecting end portion 101 is coupled in a vertical sliding sliding form to engage with each other to build a wall do. Since the steel sheet piles (hereinafter, referred to as "U-shaped sheet piles") 100 of the conventional U-shaped cross-sections are constructed in succession, the wall is not used for large-scale construction in which a large force is applied. It is a situation that is used only for the purpose, such as temporary barrier walls and water barriers that mainly support a small force.

On the other hand, in the construction of the earthquake in general, using the earthquake temporary facility using the H pile and the earth plate, this earth plate is usually made of wood, accordingly, there is a limit that it is difficult to recycle the earth plate and expect a water order. In the case of using a thin-walled, wide and lightweight U-shaped sheet pile instead of the conventional earth plate in such a construction, it is very advantageous in the construction and economics of the construction of the earthenware. However, since the conventional wall constructed by the U-shaped sheet pile 100 is not large enough to support the back soil and groundwater as described above, it is necessary for large-scale construction work that needs to support a temporary wall or other large force. There is a limit to using.

If the conventional wall constructed by the U-shaped sheet pile 100 is to be used as a structure receiving a large force, such as an earthen wall, a reinforcement pile made of a separate beam or steel pipe is additionally added to the front or rear of the wall. Must be installed. Therefore, in addition to installing the steel sheet piles in the ground, the work of installing the piles in the ground should be additionally performed, which is accompanied by an increase in the amount of steel, construction cost, and air. In particular, since the pile is further installed on the front or rear surface of the wall made of the U-shaped sheet pile 100, in addition to the thickness of the pile in the portion where the pile is installed, the thickness due to the U-shaped sheet pile 100 is more substantial. The space of thickness is encroached. Therefore, in the case of the trench construction for the installation of buildings, such a problem that the work space becomes narrow. For this reason, in the case of the U-shaped sheet pile 100, a large port, a river permanent structure and a large temporary screen construction, and a deep excavation deep earth construction, such as the situation that is not properly utilized in the site where a large force is working.

In particular, in order to make a new sheet pile, an attempt has been made to produce a new type of steel tube and H beam sheet pile by cutting only the interlocking portion of the existing U-shaped sheet pile and welding them with both steel pipes or H beams. Cutting and welding of the sheet pile interlocking part are economically lacking in economics and stability due to problems such as increase of scrap of existing materials, deterioration of joint stiffness, and difficulty in transferring back earth pressure.
