[0020] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0021] In the description of the present utility model, it should be understood that the term "including" used in the specification of the present utility model means the presence of the described features, integers, steps, operations, components and / or assemblies, but does not exclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies and / or their groups. It should be understood that when we say that a component is "connected" to another component, it can be directly connected to other components, or there may also be intermediate components. The term "and / or" used here includes all or any unit and all combinations of one or more related listed items.

[0022] Such as Figures 1 to 3As shown in the figure, the utility model relates to a slope protection lattice beam structure, which includes cross beams 1, longitudinal beams 2, anchor rods 3 and elastic filling members. A plurality of cross beams 1 are arranged at intervals longitudinally, and a plurality of longitudinal beams 2 are arranged at intervals transversely. The plurality of cross beams 1 and the plurality of longitudinal beams 2 intersect. The anchor rod 3 is arranged at the intersection of the cross beam 1 and the longitudinal beam 2 and is used to penetrate into the slope to fix the cross beam 1 and the longitudinal beam 2. A plurality of deformation joints 11 are arranged at intervals transversely on the cross beam 1, and the elastic filling member is inserted into the deformation joint 11.

[0023] In the utility model, the plurality of cross beams 1 and the plurality of longitudinal beams 2 intersect and form a network structure, which is laid on the slope, so as to be able to solidify the soil on the slope, and has resistance and stability to the peeling of the surface layer of the slope, and landslides can be avoided. Then, the anchor rod 3 is arranged at the intersection of the cross beam 1 and the longitudinal beam 2 and penetrates into the slope, so as to achieve the fixing effect and stabilize the network structure on the slope. Then, a plurality of deformation joints 11 are arranged at intervals transversely on the cross beam 1, and the elastic filling member is inserted into the deformation joint 11. The elastic filling member does not affect the free expansion and contraction of the slope protection lattice beam structure, and can also prevent soil or stones from accumulating in the deformation joint 11 and blocking the deformation joint 11, and finally causing the slope protection lattice beam structure to crack.

[0024] In this embodiment, the elastic filling member is asphalt hemp wadding. The asphalt hemp wadding itself has strong deformation characteristics, so as not to affect the free expansion and contraction of the slope protection lattice beam structure. At the same time, due to the setting of the asphalt hemp wadding, it can avoid completely blocking the deformation joint 11, and the water in the slope protection lattice beam structure can flow out through the asphalt hemp wadding, so as to avoid local water accumulation and scouring in the slope protection lattice beam structure.

[0025] In this embodiment, the slope protection lattice beam structure further includes a coping beam 4. The coping beam 4 is connected between the upper ends of the plurality of cross beams 1, so as to enhance the stability of the slope protection lattice beam structure. At the same time, a plurality of the deformation joints 11 are also arranged at intervals transversely on the coping beam 4, and the asphalt hemp wadding is also inserted into the deformation joint 11.

[0026] In this embodiment, the slope protection lattice beam structure further includes a foundation beam 5. The foundation beam 5 is connected between the lower ends of the plurality of cross beams 1, so as to enhance the stability of the slope protection lattice beam structure. At the same time, a plurality of the deformation joints 11 are also arranged at intervals transversely on the foundation beam 5, and the asphalt hemp wadding is also inserted into the deformation joint 11.

[0027] In this embodiment, a plurality of lattice frames are formed between the plurality of cross beams 1 and the plurality of longitudinal beams 2, and a slope protection layer 6 is arranged in the lattice frames, so as to further improve the protection effect on the slope.

[0028] Specifically, the slope protection layer 6 is a grass planting layer to strengthen the protection of the slope.

[0029] In this embodiment, the anchor rod 3 is a deformed steel bar to have sufficient strength to ensure the stability of the slope lattice beam structure.

[0030] In this embodiment, the cross beam 1, longitudinal beam 2, coping beam 4 and foundation beam 5 are all cast with C25 concrete to ensure the stability of the slope lattice beam structure.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
