Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcement grid for a retaining wall,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing grid provided on a reinforced earth retaining wall and a method of constructing the reinforcing earth retaining wall using the same.

In general, when the cut surfaces, sloped walls, sloped surfaces, etc. formed in a new apartment, a residential complex, or a roadside are left untouched, there is a possibility that secondary damage may occur due to collapse due to rain or earthquake. A separate civil structure such as a retaining wall is constructed and installed as a method for preventing the collapse of the earth.

Such a wall structure is a wall structure made to prevent the soil from falling behind by resisting the earth pressure. It is installed to prevent the ground collapse which occurs when the ground is made steeply sloping than the stable inclination angle (angle of repose).

Such a retaining wall structure is conventionally constructed by stacking concrete blocks in multiple stages or by pouring concrete. Such a retaining wall is composed of a vertical wall constructed vertically at a certain height from the ground and a backfill soil filled in the rear surface.

The backfill soil is a very good construction material that can be easily obtained at a construction site, but the soil itself is a solid-state discontinuity and has no tensile strength.

Accordingly, in order to construct a more structurally reinforcing earth retaining wall, a reinforcing material such as geogrid, steel, or wood having a strong tensile force is installed at a constant interval in the rebuilt soil material, thereby causing frictional force between the earth and the reinforcement. The strength can be increased.

Meanwhile, the blocks stacked in a multi-stage structure to form the vertical wall may be formed by connecting or fixing one end of the stiffener to the backside of the block using a separate connecting member such as a connecting pin or a ring, The soil and the back surface of the block are formed as an integral structure by the frictional force between the soil and the reinforcement to resist the earth pressure.

However, since the reinforcing material has a two-dimensional planar shape, the reinforcing material has a limitation in increasing the frictional force by enlarging the contact area with the backfill and increasing the drag against the collapse of the backfill by the increased frictional force.

Particularly, there is a problem in that a drag for horizontal external force transmitted when an earthquake occurs is very weak, so that there is a high risk of collapse due to lateral external force, and a separate reinforcing structure is required to reinforce it.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a three-dimensional three-dimensional structure by a simple structural modification of intersecting wire rods, A reinforcing grid for a retaining wall capable of enhancing the seismic performance of the retaining wall structure by increasing the drag in the lateral direction and a method of constructing the retaining wall using the same.

The entire length of the curvilinear wire 121b is perpendicular to the length of the upper convex 122, Is formed relatively longer than the straight line member 121a.

Since the straight line member 121a maintains the entire length of the reinforcing grid extending to the side of the embankment with the rear surface of the wall portion, the gap between the first wire member and the first wire member can be made constant. It is possible to prevent the upper convex portion 122 from being deformed so as to be convex upward.

The width W of the upper convex portion 122 or the lower convex portion 123 formed on the curved wire rod 121b of the second wire rod increases the contact area with the gravel and increases the convex or lower So as to stably maintain the shape of the convex curve, the first wire 110 may be formed to have a gradually increasing size at a portion intersecting the first wire 110.

The protruding height H of the upper convex portion 122 and the lower convex portion 123 formed between the adjacent first wire rods is greater than the protrusion height H of the first wire rods 121a intersecting the straight wire rods 121a of the second wire rods The first wire rods 110 and the first wire rods 110 intersecting with the straight wire rods 121a of the second wire rods 110a and 110b are formed to be constant in the longitudinal direction of the rectilinear wire rods, (H) by increasing or decreasing the spacing between the protrusions.
