detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, it is an embodiment of the flexible ecological retaining wall slope protection system of the present invention. The slope protection system of the flexible ecological retaining wall in this embodiment includes: multi-layer honeycomb cells 10, filling materials and plant planting layers (not shown in the figure). Wherein, the multi-layer honeycomb cells 10 are stacked sequentially from bottom to top along the side slope to form a stepped wall. Preferably, a base layer 20 is provided below the multi-layer honeycomb cells 10 , that is, the multi-layer honeycomb cells 10 are stacked sequentially on the base layer 20 . The foundation layer 20 is a soil filling layer, which provides a flat base surface for the stacking of the multi-layer honeycomb cells 10 . During the construction of the base layer 20, the soil layer needs to be compacted layer by layer, and the compaction coefficient K≥0.9. The filling material is filled in the honeycomb cell 10, and the filling material can be sandstone or concrete, or can be filled with concrete and sandstone at the same time. Preferably, the particle size of the filling material is uniform, and the maximum particle size is not greater than 5 cm, and the thickness of each layer of filling material is not greater than 30 cm and less than 25 cm. Moreover, after the filling material is filled, it should be leveled first, and then it can be rolled and compacted. The plant planting layer is covered on the stepped surface of the stepped wall.

The wall body of the above-mentioned flexible ecological retaining wall slope protection system of the present embodiment is formed by stacking multi-layer honeycomb cells 10 successively, and filling materials are filled in the honeycomb cells 10, and the friction between the filling materials and the honeycomb cells 10 is utilized. The resistance and the lateral restraint force of the honeycomb cell 10 on the filling material form a wall structure with greater shear strength and rigidity. On the one hand, due to its own gravity effect, the layered honeycomb cells 10 resist the lateral displacement of the fill behind the wall, ensuring the stability of the embankment behind the wall, and the greater shear strength and rigidity of the wall structure also ensure its own stability. On the other hand, the wall structure formed by stacking honeycomb cells 10 has a certain degree of flexibility, and a certain amount of lateral deformation can occur between the honeycomb cells 10 itself and adjacent honeycomb cells 10, thereby reducing the The lateral earth pressure can better adapt to the deformation of the foundation, and has low requirements on the bearing capacity of the foundation, and the stress will be redistributed after deformation without sudden failure. Therefore, the flexible ecological retaining wall slope protection system has a relatively large bearing capacity. In addition, the step surface of the stepped wall is covered with a plant planting layer. After the flexible ecological retaining wall slope protection system is stacked, plant seeds can be spread on the plant planting layer, and the plant planting layer provides a growth environment for the plant seeds.

Preferably, the reinforced layer 30 is provided with multiple layers, and the multi-layered reinforced layers 30 are arranged between the multi-layered honeycomb cells 10 at equal intervals. In this embodiment, a reinforcement layer 30 is provided between every two layers of honeycomb cells 10 . Of course, the interval between two adjacent layers of reinforced layers 30 is not limited to the two layers of honeycomb cells in this embodiment, but can be selected and set according to the actual construction environment. The reinforced layer 30 is a geogrid, which has relatively high tensile strength. On the one hand, the lateral displacement of the wall structure is directly limited by the tensile properties of the reinforcement layer 30 . On the other hand, the reinforcement layer 30 limits the lateral deformation of the filling material in the honeycomb cell 10 through its interface effect, improves the shear strength of the filling material, and shares part of the pressure of the filling material, which correspondingly improves the The bearing capacity of the entire cavity structure. The wall structure composed of honeycomb cells 10 will not only produce rigid body displacement but also flexural deformation under the action of external load, while the reinforced layer 30 has obvious bending resistance in addition to exerting the tensile effect , so the overall structure formed by the reinforced layer 30 and the honeycomb cell 10 has a great bearing capacity.

Furthermore, the slope protection system of the flexible ecological retaining wall in this embodiment also includes a geotextile 40 and a drainage pipe 50 . The geotextile 40 is laid on the side slope, and is located between the side slope and the honeycomb cell 10, which can play the role of drainage and anti-seepage. The drainage pipe 50 is arranged on the side slope, and the geotextile 40 covers the drainage pipe 50, thereby realizing the drainage of the flexible ecological retaining wall slope protection system.
