Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
As Figure 1-Figure 8, the utility model includes multiple retaining wall units arranged side by side, the retaining wall unit It include bottom plate 1, vertical plate 2 and counterfort 3, bottom plate 1, vertical plate 2 and counterfort 3 are reinforced concrete structure, and the bottom plate 1 is lain in On ground 9, groove 6 is reserved in the installation place of 1 top surface upper vertical plate 2 of bottom plate and counterfort 3, and groove 6 is T-shaped.It is equipped in 6 edge of groove Multiple vertical single ended bolts 7, single ended bolt 7 is L-shaped, and single ended bolt 7 is threaded together with the reinforcement welding in bottom plate 1 Bar portion perpendicular to bottom plate 1, screw thread is exposed at outside bottom plate 1, and screw thread starts from 1 top surface of bottom plate.As shown in Figure 7,8, two adjacent earth-retainings Spiral shell is used after overlapping using the opposite face of tenon structure connection or two bottom plates 1 using L-shaped structure between the bottom plate 1 of wall unit It tethers the mode connect to connect, to increase the globality of barricade engineering.The vertical plate 2 and counterfort 3 is placed in bottom plate perpendicular to bottom plate 1 On groove 6 in, and pour into groove 6 neat slurry and vertical plate 2 and counterfort 4 be fixed in groove 6.Counterfort 3 is perpendicular to vertical Plate 2, the supporting surface of counterfort 3 and the rear-face contact of vertical plate 2.
