The present invention relates to an assembled retaining wall.

In general, the retaining walls are constructed on naturally inclined surfaces or artificially formed inclined surfaces, such as artificially inclined surfaces due to road and railway construction. Such a retaining wall can be classified into a fill site retaining wall and an incision retaining wall according to its installation form. The fill site retaining wall is constructed in an architectural complex, and the cut site retaining wall is constructed between the cut cut surface and the construction base surface when constructing a road or cutting a part of the mountain in the form of crossing the mountain.

1 is a perspective view illustrating a retaining wall constructed on a roadside as a typical example of a construction of a conventional retaining wall.

Referring to FIG. 1, the retaining wall 100 is installed at a boundary between an inclined cutout 200 and a road 300 which is a construction plane. Such a retaining wall 100 forms a formwork to cast concrete to support the earth pressure of the incision 200.

However, the existing retaining wall 100 has a problem in that it is difficult to transport the material to the site as the retaining wall 100 is constructed only with relatively large concrete along the incision 200. In addition, the concrete retaining wall 100 has a hassle that must be carried out strict management so that surface loss due to rainwater, damage to the concrete due to load or impact does not occur until after the concrete is solidified sufficiently. In addition, the concrete retaining wall 100 has a problem that requires a lot of manpower and cost for its construction and maintenance because it is necessary to check the crack phenomenon over time even after the construction from time to time to perform the appropriate repair work. In particular, the concrete retaining wall 100 has a problem that it is very difficult to construct the higher the height of the incision because the restriction is also followed by the height that can be constructed.

On the other hand, since the existing concrete retaining wall 100 is constructed only for the purpose of securing a support base, there is a problem that does not match the surrounding environment at all. In other words, the existing concrete retaining wall 100 has a problem that does not fit at all with the surrounding environment because it is constructed in a structure suitable only for the purpose of preventing deformation and collapse due to the loss of soil in the incision.

Therefore, the present invention was devised to solve the general problems of the existing retaining wall, for example, the cut retaining wall made of concrete,

The rainwater penetrating into the incision 10 is also drained through the drain pipe 371 inserted into the incision 10. At this time, as the inclined drainage hole 37 is located directly above the planting stand 36 as shown in FIG. 5B, the rainwater drained through the drainage pipe 371 falls on the planting stand 36 and is used for vegetation of the tubular plant. Used as

As described above, the assembled retaining wall according to the present invention is constructed by stacking each retaining wall panel in the up, down, left, and right directions by a wedge-shaped support stand, so that the construction work is easy and maintenance and repair work can be performed easily. have. In addition, by supporting the wedge-shaped strut by the first catching ring, the connecting wire and the buried block, the retaining wall panel can be firmly supported as a result, thereby maintaining the initial construction state continuously. In addition, there is an advantage that can be appropriately harmonized with the surrounding environment of the city plant by placing a planting groove for the tubular plants to vegetation on the front of each retaining wall panel.
