Description
SUPPORTING MEMBER, RETAINING WALL STRUCTURE HAVING THE SAME AND BUILDING METHOD THEREOF
Technical Field
[1] The present invention relates to a retaining wall structure; and more particularly, to a supporting member interposed between adjacent two horizontal retaining wall layers for supporting and coupling units of the retaining wall, a retaining wall structure having the same and a method of building the retaining wall structure. Background Art
[2] A retaining wall is a structure erected to support a road slope and an excavated or filled embankment in order to prevent collapse of the road slope and the embankment due to the earth pressure. Generally, the lateral displacement is prevented by filling-up a space between the retaining wall and the road slope or the embankment with the back-filler containing fiber reinforcement having high tension and friction, i.e., geo- grid. That is, the retaining wall assures the stability of diversity structures such as road slopes and the embankments. Therefore, various retaining wall structures and methods of building thereof were introduced. For example, interlocking blocks were used to build a retaining wall that supports the earth pressure of a soil structure. Also, sand sacks or soil sacks were used instead of using the interlocking blocks.
[3] When the sand sacks or the soil sacks are used to build the retaining wall, the retaining wall is built without fixing those sacks each others and their positions in the retaining wall are maintained only by their gravity. Therefore, if the back-filler portion of the retaining wall is sunken after building the retaining wall with those sacks, the vertical shape of the retaining wall is easily deformed by the horizontal shearing force arisen between the retaining walls. As a result, the reinforcement, i.e., geo-grid, in the back-filler is destroyed. Therefore, the retaining wall according to the related art has highly limited conditions of the height and the slop, and the durability thereof is low. Disclosure of Invention Technical Problem

[30] FlG. 1 is a perspective view of a retaining wall structure according to an embodiment of the present invention, and FlG. 2 is a cross-sectional view of a retaining wall structure with a supporting member according to an embodiment of the present invention.
[31] As shown in FIGS. 1 and 2, the retaining wall structure according to the present embodiment includes: a first horizontal retaining wall layer 100; a second horizontal retaining wall layer 200 formed on the first horizontal retaining wall layer 100 in parallel; a third horizontal retaining wall layer 300 formed on the second horizontal retaining wall layer 200 in parallel; and supporting members 10 and 20 nailed on the second horizontal retaining wall layer 200 and the third horizontal retaining wall layer 300, respectively.
[32] The first horizontal retaining wall layer 100 is formed of a plurality of first retaining wall units 110 which are closely and horizontally arranged each others. The second horizontal retaining wall layer 200 is also formed of a plurality of second retaining wall units 210 closely and horizontally arranged each others on the first horizontal retaining wall layer 100. The third horizontal retaining wall layer 300 is also formed of a plurality of third retaining wall units 310 closely and horizontally arranged one another on the second horizontal retaining wall layer 200. It is preferable that the first, the second and the third retaining wall units 110, 210 and 310 may be a sand sack or a soil sack. Also, those retaining wall units 110 and 210 may be a sack containing the composition of the sand and the soil. Instead of using the sand sack, the soil sack or the composition thereof, blocks made of material having characteristics of gradual hardening may be used. For example, the first, the second and the third retaining wall units 110, 210 and 310 may be wet clay blocks which are hardened after completely building the retaining wall.
[33] Each of the supporting members 10 and 20 includes: a pair of downward protrusions 11 or 21 that are spaced apart and extended in one direction; and coupling portion 13 or 23 for coupling one ends of the downward protrusions 11 or 21. The coupling portion 13 or 23 is connected to both of the one ends of the downward protrusions 11 or 21 about vertically. In order to support vertically adjacent retaining wall units such as the first retaining wall unit 110 and the second retaining wall unit 210 or the second retaining wall unit 210 and the third retaining wall unit 310, the protrusions 21 of the supporting member 20 are inserted into the first retaining wall unit 110 after passing through the second retaining wall unit 210, and the protrusions 11 of the supporting member 10 are also inserted into the second retaining wall unit 210 after passing through the third retaining wall unit 310. Accordingly, the coupling portions 23 and 13 are positioned on a top surface of the second retaining wall unit 210 or the third retaining wall unit 310, respectively.

[35] As shown in FlG. 3, the supporting member 10 includes a pair of downward protrusions 11 that are spaced apart and extended in one direction and a coupling portion 13 for coupling one ends of the downward protrusions 11 together. The coupling portion 13 is connected to each of the one ends of the downward protrusions 11 about vertically. As shown in FlG. 4, the supporting member may further include upward protrusions 22 extended from the coupling portion 23 in a direction opposite to the extending direction of the downward protrusions 21.
[36] FIGS. 5 and 6 show arrow-headed protrusions of the supporting member. The pair of downward protrusions 11 or 21 may have arrowhead shaped portions 14 and 24 at projected ends thereof so that the downward protrusions are not easily taken off from the sand sack or the soil sack after the downward protrusions are inserted into the soil sack or the sand sack. It is preferable that the arrowhead portions 14 and 24 have a shape of full arrowhead or a shape of half arrowhead as shown in FIGS. 5 and 6. Also, the downward protrusions may have sharp cone shaped end portions to be smoothly nailed into the retaining wall units as shown in FlG. 7. Furthermore, it is possible to shape the end portions of the downward protrusions to be rounded as shown in FlG. 8 because the downward protrusions is made to have a shape of thin bar. Moreover, the downward protrusions may be formed in a hook shape. Such arrowhead shaped portions 14 and 24 allow the supporting members to firmly connect the first retaining wall unit 110 and the second retaining wall unit 210 or the second retaining wall unit 210 and the third retaining wall unit 310.
[37] The retaining wall structure according to the present embodiment further includes a first geo-grid sheet 510 having one end interposed between the first horizontal retaining wall layer 100 and the second horizontal retaining wall layer 200.

The other end of the geo- grid sheets 510 and 520 is extended into the filling such as the back-filler soil supported by the retaining wall units 110, 210, 310 and 410. A plurality of through holes 511 and 521 is formed on the geo-grid sheets 510 and 520. The downward protrusions 31 pass through the through holes 511 and 521 and then inserted into the first and the second retaining wall units. Therefore, the first and the second geo-grid sheets 510 and 520 are stably interposed and firmly fixed between the horizontal retaining wall layers 100, 200, 300 and 400.
[44] The retaining wall according to another embodiment is described as including only four horizontal retaining wall layers 100, 200, 300 and 400. However, it is obvious to those skilled in the art that the present invention can be embodied identically into a retaining wall having more than five horizontal retaining wall layers.
