Abstract: A geogrid connecting structure of a retaining wall is provided to construct a retaining wall conveniently, economically and stably by bolting a vertical member and a horizontal member at the backside of a retaining wall and coupling geogrid to the horizontal member, and bolting fixing plates and stiffening plates to the geogrid. A geogrid connecting structure of a retaining wall is formed by bolting a horizontal member(2) having a C-shaped cross section between a vertical member(1) and a vertical member, and fastening geogrid(3) to the horizontal member, wherein a first fixing plate(4) and a second fixing plate(4') provided with many long holes(41,41') are installed on the upper and lower parts of the geogrid to fasten bolts to three long holes formed in the middle of the first fixing plate, the geogrid, and three long holes formed in the middle of the second fixing plate, and a first stiffening plate(5) provided with a first fastening hole(51) and a second fastening hole(52) and a second stiffening plate(5') provided with a first fastening hole(51') and a second fastening hole(52') are attached on two ends of the first fixing plate and the second fixing plate in an orthogonal direction to fasten bolts to the first fastening hole of the first stiffening plate, the long hole of the first fixing plate, the geogrid, the long hole of the second fixing plate and the first fastening hole of the second stiffening plate, thereby to heighten the fastening strength of the geogrid, and the horizontal member is formed in a C-shaped cross section to be higher than the geogrid bolted with the first stiffening plate, the first fixing plate, the second fixing plate and the second stiffening plate and provided with a first coupling hole(211) and a second coupling hole(221) on an upper side(21) and a lower side(22) to make one end of the geogrid bolted with the first stiffening plate, the first fixing plate, the second fixing plate and the second stiffening plate to the inside of the horizontal member inserted to the inside of the horizontal member and fastened to the first coupling hole of the upper side of the horizontal member, the second fastening hole of the first stiffening plate, the second fastening hole of the second stiffening plate and the second coupling hole of the lower side, thereby to make the geogrid move freely in the horizontal member not to be damaged when pressing a roller for soil filling work.

Abstract translation: 提供挡土墙的土工格栅连接结构，通过在挡土墙的后侧螺栓固定垂直构件和水平构件，并将土工格栅与水平构件相结合，方便地，经济地和稳定地构造挡土墙，以及螺栓固定板和加固 盘子到土工格栅。 通过在垂直构件（1）和垂直构件之间螺栓固定具有C形横截面的水平构件（2）并将土工格栅（3）紧固到水平构件，形成挡土墙的土工格栅连接结构，其中， 第一固定板（4）和设置有多个长孔（41,41'）的第二固定板（4'）安装在土工格栅的上部和下部，以将螺栓紧固到形成在中间的三个长孔 第一固定板，土工格栅和形成在第二固定板的中间的三个长孔，以及设置有第一紧固孔（51）和第二紧固孔（52）的第一加强板（5）和第二加强板 设置有第一紧固孔（51'）和第二紧固孔（52'）的板（5'）在正交方向上安装在第一固定板和第二固定板的两端，以将螺栓紧固到第一紧固 第一加强板的孔，第一固定板的长孔， id，第二固定板的长孔和第二加强板的第一紧固孔，从而提高土工格栅的紧固强度，水平构件形成为高于土工格栅的C形横截面 与第一加强板，第一固定板，第二固定板和第二加强板螺栓连接，并在上侧（21）和下侧设置有第一联接孔（211）和第二联接孔（221） （22）使得将所述土工格栅的一端用第一加强板，第一固定板，第二固定板和第二加强板螺栓连接到插入水平构件的内部的水平构件的内部，并紧固到 水平部件的上侧的第一连接孔，第一加强板的第二紧固孔，第二加强板的第二紧固孔和下侧的第二连结孔， e土工格栅在水平构件上自由移动时，不要因为土壤填充工作而滚动辊而损坏。
