Description

Freestanding mudguard structure using two rows of H beam and high strength steel plate and construction method

The present invention is a self-supporting earthquake structure using a two-row H-beam and a high-strength steel plate installed to prevent soil and groundwater from entering the construction site when the excavation work for the underground structure construction work, etc. It is related to, more specifically, the installation of thumb piles and freestanding piles in two rows, install the earth wall between the thumb pile and the thumb piles, and install a freestanding steel plate between the thumb pile and the freestanding piles so that the soil is introduced into the construction site The present invention relates to a self-supporting earthquake structure using a high strength steel plate and a two-row H-beam capable of preventing the earthquake wall from flowing or deforming, and a construction method thereof.

The ground is excavated by extending the ground in a predetermined depth and length direction, such as a building, an open tunnel, a subway, an electric power port, a communication port, and a sewer pipe, and install a structure in the internal space of the excavated ground.

In other words, in the underground construction of the construction site, the earthquake construction is temporarily preceded by digging soil to prevent the collapse of the surrounding soil. The earthquake structure is a structure installed for such a earthquake construction. Also called earth wall.

In particular, the land use of Korea is mainly concentrated in large cities, and due to the lack of available land, high-rise and high-density urban areas are accelerating. As the use of high-rise and densified lands increases the size of underground structures, close construction with neighboring buildings is inevitable, and the slopes, cracks, and collapses of nearby buildings, including settlement of adjacent roads, It is a frequent occurrence, resulting in a number of social problems caused by a number of complaints and civil and criminal disputes, including property loss. Therefore, the selection of construction method and member for earth wall temporary construction work in underground excavation has emerged as a very important factor.

In general, in order to prevent the collapse or spillage of soil at the edge of the ground excavation section during construction of underground construction of a building, or incision site during civil works, H-beams are fixed to the ground at a predetermined depth, and then fixed. The earthen board construction is made of sandwiching the earth plate between the H-beam, generally the earth plate is made of wood or bent iron plate.

Accordingly, after the H-beams are put on the ground, the earth and sand are excavated to a certain depth, and the earth and sand plates are sandwiched between the H-beams so that the surrounding soil is not introduced into the construction site.

At this time, the earth plate should have the flexural strength (compressive strength) that can support the earth pressure acting on the underground incision surface. If the flexural strength is insufficient compared with the earth pressure, shear failure of the earth plate will occur and the flange of the H-beam will be broken. Escape from and leads to the collapse of the soil.

Therefore, in order to achieve the purpose of the earth block, the earth plate should have both flexural strength and compressive strength to cope with the earth pressure, and the H-beam serves as a support to prevent the earth plate from being pushed back.

However, since the flexural strength of the earth plate increases as the material thickness increases, and the specific gravity or density of the material increases, the volume or weight of the earth plate becomes large when the earth plate is applied to the earthquake construction that requires high earth pressure. There were only disadvantages.

In addition, when the width of the earth plate is widened, the earth plate is bent due to the earth pressure.

In addition, the span is not constant when the H-beam is embedded to install the earth plate. In the case of the wood earth plate, the span, which is the interval of the H-beam, is measured one by one, and the individual wood earth plate is cut and inserted into the saw material. Loss and installation is inconvenient, the installation time and installation cost are excessive, and disassembly is almost impossible due to earth pressure.

In addition, although it must be dismantled and collected, it is difficult to be recycled due to uneven specifications, which are each cut and dismantled, so that it is usually buried as it is not dismantled. I'm concerned.

In addition, in the case of a conventional earth plate made of steel or synthetic resin, since it is usually manufactured by a known method, it is generally applicable at a relatively shallow digging depth of 6.0 m, but cannot be applied at a depth that requires more depth. There is this.

In general, in order to prevent the collapse of earth and sand in the digging or embankment work, temporary materials such as long woods having a rectangular cross section are stacked and provided. In the digging or embankment work, H beams with a predetermined interval are installed between the H beams. The temporary materials are stacked in order to prevent the outflow of soil from the excavated and filled basement walls into the underground space.

However, the cost is increased due to the use of expensive wood, and because the wood is decayed, it is difficult to reuse the next construction.

In addition, there is a problem in that the utilization of the internal space of the trench is inferior by having to reinforce it with a brace (STRUT, CONER STRUT, RAKER, EARTH ANCHOR), etc. in the trench.

In order to solve this problem, a chair-type earthenware (CSR) method is proposed.

The chair-type mudstone method refers to a self-standing mudstone method that combines a heat transfer pile that acts as a wall and a rear pile that acts as a thumb pile to prevent shear destruction of the soil wall. In particular, by removing the mutual soil between the heat transfer and after heat piles with relatively high earth pressure to a certain depth, and installing a band on the back pile pile, the earth pressure was excavated and improved to 10M, and it can be excavated up to 30M when combined with the earth anchor method. Do.

However, this also has a problem that the construction is complicated and takes a long time.

Korean Registered Patent [10-1179770] discloses a structure for constructing an earthen fence and a method for placing an earthen fence.

Therefore, the present invention has been made in order to solve the problems as described above, the object of the present invention is to install a thumb pile and a freestanding pile in two rows, install a masonry wall between the thumb pile and the thumb pile, thumb pile and It is to provide a self-supporting earthquake structure using a two-row H-beam and a high-strength steel plate that can be installed to prevent sediment or groundwater from entering the construction site by installing a freestanding steel plate between freestanding piles.
