Description

Double Continuous Walls {Wall-Foundation system}

The present invention relates to a double continuous wall, and more particularly, to a double continuous wall that can prevent the collapse of the soil during construction, underground trench construction or retaining wall construction and protect adjacent buildings.

In general, when digging work for the installation of civil engineering works, underground structures of large, large buildings, etc., construction of the earthquake blocks to prevent the soil from leaking or collapsing from the underground walls.

Such earthquake construction is carried out while digging or installing a barrier in the ground in advance, and this excavation work is carried out in various ways depending on the surrounding environment, the soil condition of the ground, and the layout of buildings around the construction site. .

Korean Unexamined Patent Publication No. 2003-0051477 discloses an underground continuous wall construction method. The published continuous construction method is a method of constructing an underground continuous wall by repeatedly placing reinforced concrete walls using equipment such as a cutter, and installing an earth barrier facility supporting the underground continuous wall. In order to support the continuous continuous wall by placing a plurality of bracing walls in the direction perpendicular to the underground continuous wall while contacting the underground continuous wall.

Registered Utility Model No. 20-0229224 discloses a structure for installing earthen boards for earthquake construction. The posted installation structure includes a plurality of foundation piles installed at intervals inside the soil wall, a earth plate made of a solid material laminated on one side of the foundation pile to prevent the soil from being collapsed or spilled, and the earth plate coupled to the foundation pile. It is provided with a coupling means to be detachable.

As mentioned above, the earthen board installation work for earthquake construction is required to install the earthen board on the foundation pile, so that the single construction is difficult, and the construction is impossible without the trench. In addition, since the earth plate is made of wood, it is bent or eroded by moisture when used for a long time, and even if it is not corroded, it is impossible to recover because it is buried in the ground due to the work between the earth wall and the earth plate. Therefore, the conventional earth plate is not recycled, there is a problem that resources are wasted, the cost is increased.

In addition, Korean Patent No. 10-0401330 discloses another example of the building construction method. The posted piling method involves placing the thumb piles in the H-beams in perforated holes in the ground, securing the braces to the upper ends of the thumb piles, and digging between the thumb piles in front of the thumb piles and then behind them. Insert the rear panel, connect both sides of the reinforcing bar with connecting bars of the thumb piles, close the panel in front of the thumb pile and backfill the trench, and place concrete between the front panel and the rear panel. Immediately removing the rear panel and curing the concrete while filling the concrete where the rear panel was.

This method has a problem that requires a lot of work during construction because the front panel and the rear panel must be coupled to and separated from the thumb pile. The complexity of such construction causes the cost of construction to increase by increasing labor costs.

On the other hand, the conventional retaining wall as described above has a weak bearing capacity when there is severe earth pressure by the buildings of caution there is a fear of collapse. In particular, there is a problem that cracks occur in the surrounding buildings when the earth pressure cannot be tolerated. In particular, it is possible to fundamentally prevent the earth pressure from being transmitted from the construction site or the surroundings of the construction site, causing the mound wall to collapse or damage the adjacent building.

The present invention is to solve the problems described above, it is possible to fundamentally prevent the collapse by the earth pressure, and to provide a double continuous wall that can increase the bearing capacity for earth pressure.
