Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retention mechanism and a retention method,

The present invention relates to an earth retaining apparatus and a construction method, and more particularly, to prevent a collapse due to the destruction of a soil plate in response to the earthquake, And a retention device and an earth retaining method that can be applied as a temporary construction in a reinforced construction site.

Generally, in order to prevent collapse or outflow of the soil, the H-beam is fixed at a predetermined depth on the ground at regular intervals on the ground, and then the H- The earthwork is constructed by sandwiching the earth plate between the beams. In general, the earth plate is made of wood or a bent iron plate.

After the H-beam is applied to the ground, the soil is excavated to a certain depth, and the earth plate is sandwiched between the H-beams to prevent the surrounding soil from flowing into the construction site.

At this time, 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 horizontal earth pressure, shear fracture of the earth plate occurs Which leads to the collapse of the earth.

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.

These soil plates are laminated between several H beams vertically fixed at regular intervals on the ground to secure safety from collapsing by temporarily blocking the collapse of soil during civil engineering work, And the cushion membrane is a facility material to prevent the collapse of soft ground.

The related art and problems related to the sanitary plate proposed recently will be described below.

However, according to the related art structure for installing a soil plate for earthwork, there is a problem in that when the stress is generated in the longitudinal center of the soil plate, the buckling phenomenon and the connection portion are easily broken and deformed.

2. A soil plate having a reinforcing member of Registration No. 20-0214388 has a H beam type speckle which is installed at regular intervals and a soil plate which is sequentially stacked and laminated between the adjacent spacers; The protrusions are protruded by a predetermined length in the longitudinal direction at the center of the upper surface. The protrusions are formed at the bottom surface of the protrusions and have a shape corresponding to the protrusions. And a metal coating portion having a thin metal plate attached to the front surface, the top surface, and the bottom surface, wherein the metal coating portion is formed at a predetermined distance from the first perpendicular plate and has the same height and thickness, A second vertical plate having a bottom surface formed with an insertion groove having a shape corresponding to the protruding portion, and a second vertical plate having a center of a corresponding surface of the first vertical plate and the second vertical plate, A horizontal connection plate extending in the longitudinal direction and having an 'H' -shaped cross section, The reinforcing plate connecting the first and second vertical plates and the horizontal connecting plate on both sides is made of synthetic resin.

However, the conventional artificial soil board having a reinforcing member is made of a synthetic resin material without using wood or steel, which is advantageous in terms of weight reduction and recycling, but has a problem in that it is less smooth than stressed wood due to soil behavior, There is a problem that the manufacturing cost is increased when the strength of the reinforcing member is increased by inserting the reinforcing member therein.
