For slopes above the water level line, considering the aesthetics of the slope and the economy of the project, lattice beam support is often used more. The lattice beam nodes are combined with anchor bars or anchor bar piles, and prestressed anchor cables can be additionally installed in the parts corresponding to the fully weathered and deep overburden layers. When constructing the lattice beam, the soil slope surface is usually grooved and then the lattice beam is poured, and grass planting is carried out inside the lattice beam.

[0025] The following further elaborates on the present utility model in conjunction with the attached Figure 1-2 drawings.
[0026] Please refer to the drawings in the specification Figure 1 , an embodiment provided by the present utility model: a prefabricable lattice beam, including a slope 7, with a lattice beam formed by a cross beam 1 and a longitudinal beam 2 arranged on the outer side of the slope 7, and the longitudinal beam 2 vertically downward along the slope surface of the slope 7. Facilitating self-flow drainage along the shortest path during heavy rain. The two sides of the cross beam 1 are symmetrically inclined downward, and the middle of the cross beam 1 is parallel to the bottom of the slope 7. Facilitating self-flow drainage of rainwater along the shortest path during heavy rain and preventing landslide deformation of the soil slope due to rainfall.
[0027] Please refer to the drawings in the specification Figure 1 and Figure 2 , an anchor tendon bundle 4 is provided at the junction of the cross beam 1 and the longitudinal beam 2, and a plurality of hollow road surface bricks 3 are laid on the surface of the slope 7 between the cross beam 1 and the longitudinal beam 2. The longitudinal sections of the plurality of hollow road surface bricks 3 form a honeycomb structure, and an anchor cable 5 is provided at the honeycomb node between adjacent hollow road surface bricks 3. Thus, a plurality of hollow road surface bricks 3 can be prefabricated and laid between the cross beam 1 and the longitudinal beam 2. The spacing between adjacent hollow road surface bricks 3 ≥ 5 mm. Effectively preventing mutual extrusion between the hollow road surface bricks 3.
[0028] Please refer to the drawings in the specification Figure 1 and Figure 2 , side end reinforcements 6 are lapped between the hollow road surface bricks 3 and the cross beam 1 and the longitudinal beam 2 respectively, and paint layers are coated on the surfaces of the anchor tendon bundle 4, the anchor cable 5 and the side end reinforcement 6. Improving the anti-corrosion performance of the anchor tendon bundle 4, the anchor cable 5 and the side end reinforcement 6, and thereby extending the service life of the anchor tendon bundle 4, the anchor cable 5 and the side end reinforcement 6.
[0029] Working principle: When installing the cross beam 1 and the longitudinal beam 2, it is necessary to pre-install the anchor tendon bundle 4 into the slope 7 first, and then install the joint of the frame cross beam 1 and the longitudinal beam 2 onto the anchor tendon bundle 4. While vibrating, inject the frame concrete at the framed position. Apply a layer of cement mortar on the surface of the slope 7 between the frame concretes, and then lay the hollow road bricks 3 on the surface of the slope 7. The positions between the hollow road bricks 3 are fixed by the anchor cables 5 to ensure that the bricks are compacted and flat. The hollow road bricks 3 are overlapped with the cross beam 1 and the longitudinal beam 2 through the side end reinforcement bars 6. During the process of laying the hollow road bricks 3, ensure that the distance between the hollow road bricks 3 is not less than 5 mm to prevent the hollow road bricks 3 from being squeezed, and at the same time, minimize the distance between the hollow road bricks 3 to prevent a large deformation space between the cross beam 1 and the longitudinal beam 2.
[0030] When encountering heavy rainfall, rainwater will accumulate in the cross beam 1 and the longitudinal beam 2. By arranging the longitudinal beam 2 vertically downward along the slope surface of the slope 7 and arranging the two sides of the cross beam 1 obliquely downward at the same time, it is convenient for rainwater to flow by gravity along the shortest path during heavy rain, preventing the landslide from sliding and deforming due to rainfall.
