Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-supporting type earth retaining structure using two rows of H beam and a high strength steel plate,

The present invention relates to a self-supporting type earth retaining structure using a two-row horn beam and a high-strength steel plate installed to prevent soil or groundwater from flowing into a construction site when the earthquake-resistant construction is performed to construct an underground structure, More specifically, two rows of thumb piles and self-standing piles are installed, and an earth retaining wall is provided between the thumb pile and the thumb pile, and a self-supporting steel plate is installed between the thumb pile and the self-supporting pile. The present invention relates to a self-supporting type earth retaining structure using a high-strength steel plate and a two-row H-beam capable of being installed to prevent the retained wall from flowing or deforming.

A ground, a tunnel, a tunnel, a subway, a power source, a communication port, a sewage pipe, and the like are extended in a predetermined depth and longitudinal direction and excavated, and a structure is installed in the excavated ground.

That is, in the underground construction of the construction site, the earthwork is temporarily installed in order to prevent the surrounding earth from collapsing after the earth is dug. The earth retaining structure is a structure installed for the earth retaining work such as the earth retaining wall, It is also called the earth wall.

Especially, the land use status of Korea is mainly concentrated in big cities, and high - rise and high density of urban areas are accelerating due to lack of available land. As the size of the underground structure increases due to the use of the high-rise and high-density land, it becomes inevitable to construct close to the neighboring buildings, and when the underground structure is constructed, the tilting, cracking and collapse of the surrounding buildings There are frequent occurrences, resulting in a lot of social problems due to a lot of complaints and civil disputes, including property losses. Therefore, the construction method and the selection of the member for the construction of the earth wall during underground excavation are becoming very important factors.

Generally, in order to prevent the collapse or outflow of the soil, the H-beam is fixed at a predetermined depth on the ground at a predetermined interval on the ground during the construction of the underground foundation of the building, or at the edge of the ground excavation section, The earthworks is sandwiched between the H-beams. In general, the earth plate is made of wood or a bent iron plate.

Accordingly, after putting the H-beam on the ground, the soil is excavated to a certain depth, and then the soil plate is sandwiched between the H-beams, so that the surrounding soil does not flow into the construction site.

In this case, the earth plate should have a bending strength (compressive strength) capable of supporting the earth pressure acting on the undercut surface. If the bending strength is insufficient in comparison with the earth pressure, shear fracture of the earth plate occurs, And it leads to the collapse of the gravel.

Therefore, in order to achieve the purpose of the retaining structure, the earth plate should have the bending strength corresponding to the earth pressure, that is, the compressive strength and the tensile strength at the same time, and the H-beam serves as a support for supporting such soil plates from being pushed backward.

However, since the bending strength of the earth plate is increased as the specific gravity or density of the material increases as the thickness of the material increases, the volume or weight of the soil plate becomes larger when the soil plate is applied to soil- There was a disadvantage that can not be forced.

And when the width of the soil plate is widened, it is bent by the earth pressure, so that the soil plate can not be made more than a certain width.

In addition, in the case of a wooden plate, the span, which is the interval between the H beams, is measured one by one, and each wooden plate is cut with a saw to insert the material, And the installation time and installation cost are excessive, and it is almost impossible to dismantle due to the earth pressure.

Even though it is necessary to dismantle, it is difficult to be recycled due to the incompatible standards, so it is usually not dismantled, but it is buried as it is. There is concern.

In the case of a conventional plate made of steel or synthetic resin, since it is generally manufactured by a generally known method, it can be applied at a relatively shallow excavation depth of 6.0 m, but it can not be applied at a depth requiring a further depth .

Generally, in order to prevent the collapse of gravels in terra cotta work or embankment construction, it is provided by laminating a thick material such as long wood having a rectangular cross section. In the case of terra cotta work or embankment work, So that the soil can be prevented from leaking from the excavated, buried underground wall to the underground space.

However, the cost is increased because expensive wood is used, and the wood is decayed, making it difficult to reuse it in the next construction

In addition, because of the limitation of the earth pressure that can be tolerated, it is necessary to reinforce the inside of the turbine with STRUT, CONER STRUT, RAKER, EARTH ANCHOR or the like.

To solve these problems, a chair type retaining structure (CSR) method was developed.

The chair type retention method refers to a self-retaining retention method combined with a posterior pile acting as a constraining pile to prevent shear failure of the heat transfer pile and the retaining wall, which act as the retaining wall. Especially, by removing the mutual soil between the heat load and the post heat pile to a certain depth and installing a wale on the excavation surface of the post heat pile, the earth pressure is improved up to 10M of excavation height and can be excavated up to 30M simultaneously with earth anchorage method. Do.

However, this construction is complicated and requires a long construction period.

15. The method of claim 14,
The earth retaining wall guide member 160
A method for constructing a self - supporting type earth retaining structure using a two - row H beam and a high strength steel plate characterized by being a c - section steel.

A self-supporting type earth retaining structure construction method using a two-row H-beam and a high strength steel plate including a thumb pile 100, a self-supporting pile 200, a retaining wall 300, a flat- As a result,
A step (S21) of forming a thumb pile (100) in which the thumb pile (100) is installed in parallel with the excavation surface so as to be spaced apart from each other;
A step (S22) of establishing a self-standing pile (200) which is parallel to the excavation surface and which is installed at a predetermined distance from the thumb pile (100);
A pair of H-shaped guide members 550 formed by bending a steel plate so as to have a cross-section having a shape extending vertically from the end of the 'C' shape are formed on both sides of the flat- And a pair of H-shaped guide members 550 are coupled to each other so that guide grooves are formed in the longitudinal direction of the thumb pile 100 and the self-supporting pile 200 so that the self-standing pile 200 can be inserted. Joining the section steel guide member (S23);
The flat self-standing steel plate 500 to which the H-shaped steel guide member 550 is coupled is pivoted vertically to the excavation surface so that the thumb pile 100 and the self-supporting pile 200 are inserted into the guide grooves of the H- The step of establishing a flat-plate steel plate (S24); And
A step (S25) of inserting the earth retaining wall body (300) into the ground between the adjacent thumb piles (100) so as to be parallel to the excavation surface;
And a method of constructing a self - supporting type earth retaining structure using a high - strength steel plate.
