摘要
The present invention protects the reverse T-shaped retaining wall by absorbing horizontal earth pressure acting on the reverse T-shaped retaining wall from the dike of the river and enables the drainage of water penetrated into the dike to prevent the collapse of the dike. The structure for preventing the collapse of the rear portion of the river 20, the reverse T-shaped retaining wall 40 in the state of interposing the earth pressure absorbing foam material 30 on the rear surface 26 opposite to the surface 24 of the embankment 22 ) And a jaw 41 and a dowel 42 for continuous connection along the embankment 22 are formed on the left and right sides of the inverted T-shaped retaining wall 40 and fastened to the jaw 41 and the dowel 42. Balls 41a and 42a are formed, respectively, and the drain pipe 50 is driven into the bank 22 through the fastening holes 41a and 42a, and the upper surface of the base plate 43 of the inverted T-shaped retaining wall 40 is formed. A drainage passage 44 continuously connected in the longitudinal direction to the vertical wall; and a concave recess 46 is formed in the vertical wall 45 of the inverted T-shaped retaining wall 40 to insert the vegetation plate 60. , It is configured covering the opening 62 of the vegetation plate 60 with the mesh (64).;River, dike, rear, collapse, drainage, mesh, pipe, foam, earth pressure
