The fixed plate 1 is horizontally arranged under the slope toe and is contacted with the ground of the slope toe. When the gravity of the slope is applied to the fixing plate 1, the pressure of the fixing plate 1 on the slope foot ground is small because the contact area of the fixing plate 1 and the slope foot ground is large. Therefore, local collapse cannot be generated, and the slope surface is prevented from collapsing. One end and the fixed plate 1 fixed connection of dead lever 2, the other end of dead lever 2 stretches into the ground of toe, plays the fixed action, avoids fixed plate 1 to remove, and security and stability are better. The anchor bars 3 are arranged inside the fixing rod 2 to reinforce the connection between the fixing plate 1 and the fixing rod 2.

The original ground line refers to the slope shape of the side slope before construction. The step excavation refers to the step of the first level and the first level dug in the original ground line. After the steps are dug out, the ground of the slope toe is leveled so as to install the fixing plate 1.

The second step is that: the fixing plate 1, the fixing rod 2 and the anchor bars 3 are manufactured and installed.

Firstly, the hole distribution coordinates of the fixed rod 2 are determined, and holes of the fixed rod 2 are drilled. The anchor bars 3 are then inserted into the holes, the top of the anchor bars 3 being raised above a portion of the ground. The holes of the fixing rods 2 are filled with cement paste, rock powder and accumulated water in the holes are cleaned before filling, and full grouting is guaranteed in the filling process. And after the cement paste is hardened, the fixing rod 2 is manufactured, and the fixing plate 1 is manufactured in the next step. Enclosing the shape of the fixing plate 1 by the enclosing barrier, then pouring concrete into the enclosing barrier, and curing after pouring until the fixing plate 1 is completely hardened.

The third step: backfilling the soil body of the slope in layers and compacting.

And (4) backfilling the slope surface one layer above the excavated step, compacting each layer, and then filling the next layer until a proper backfilling slope surface is formed. In order to ensure the stability of the backfilled slope surface, the surface of the backfilled slope surface can be reinforced by adopting the prior art. For example, a vegetation net is laid on the backfill slope, and soil plants are planted in gaps of the vegetation net. Instead of laying the vegetation net, other suitable methods may be used.

By adopting the slope toe reinforcing structure and the construction method, the slope and the top surface soil body of the slope can be effectively reinforced, the bearing capacity of the filling slope is improved, and the settlement deformation of the side slope soil body is reduced. During construction, construction platforms such as scaffolds do not need to be built on the side slope, construction difficulty is reduced, and organization and construction are facilitated. The construction steps are fewer, the manufacturing cost is effectively reduced, and the investment is saved. Has better practical value.
