Description

Construction method and the apparatus of a ground retaining structures or walls}

The present invention relates to a device and a method for reinforcing a double earth wall for retaining wall or retaining wall. More specifically, a double steel pile is installed on the earth wall for stabilizing the slope by being built on the cut surface or the side wall of the earth surface after foundation destruction of the building. By assembling to prevent the earth wall from collapsing or being pushed by earth pressure, it can effectively prevent human accidents, and it is possible to simply disassemble and remove the double steel pile when necessary after construction to secure the safety of the building and work efficiency. The present invention relates to an earth wall forming apparatus and method for a retaining wall or a retaining wall which can be improved.

In general, when excavation works such as ground excavation works for construction of concrete structures on hillsides or hills, new lands, roads and railroads, or damage to slopes due to natural disasters occur, Or in order to maintain the stability of the adjacent ground by installing a reinforcement structure on the inclined surface of the area in order to prevent soil disintegration, settlement, and displacement of the cut surface.

1 shows an example of a reinforcing structure by the conventional earth wall method, and as shown in the drawing, the steel pile 10 of the “H” type provided with the earth plate recesses 10a on both sides at regular intervals. After placing in the ground by spaced apart between the plurality of steel piles (10) by installing a plurality of earth plate 20 in the transverse direction, by forming the earth wall consisting of the steel pile 10 and the earth plate 20 to reinforce such earth wall It is structured to prevent the collapse of soil by the structure.
