[0002] In water conservancy projects, a series of slope protection engineering measures need to be taken to prevent the slopes of river embankments from being affected by natural disasters such as erosion, collapse or landslide. The current slope protection measures often include earth and stone slope protection, greening slope protection, stone slope protection, reinforced concrete retaining wall and geogrid.

[0003] However, among the above-mentioned slope protection methods, a single slope protection method often has low slope protection capacity. At present, there are also green slope protection methods combined with other slope protection methods to adopt a composite slope protection structure. However, the above-mentioned composite slope protection structure has the following problems. Due to the inclination angle of the slope, rainwater tends to flow out of the slope under the action of gravity, and due to the obstruction of other slope protection structures, the green slope protection vegetation located in other slope protection structures cannot be effectively irrigated by rainwater, which easily leads to a low survival rate of green plants. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3The utility model provides an implementation scheme: in order to solve the problem of soil loss on the slope in water conservancy projects, a composite slope protection structure is used when protecting the slope. Except for the plant reinforcement module, other modules cannot effectively utilize rainwater or store water, resulting in a waste of water resources, limiting plant growth, and having a poor effect in reinforcing the slope.

[0024] In order to effectively utilize rainwater, a plurality of transversely connected slope reinforcement bodies 3 are laid on the felt cloth layer 2. The plurality of slope reinforcement bodies 3 constitute a whole network structure laid flat on the slope, which not only provides an anchoring effect but also provides a growth space for plants. The specific slope reinforcement body 3 is a polygonal structure plate. A planting groove 5 is opened in the center of the slope reinforcement body 3 for planting green vegetation. This method is an extended application of the porous structure slope protection. A guide groove 4 is opened on the surface of the slope reinforcement body 3. The guide groove 4 is a rectangular structure groove and the number corresponds to the slope reinforcement body 3. The number of sides, when the polygonal slope reinforcement bodies 3 are closely arranged with each other, one end of the diversion groove 4 passes through the side of the slope reinforcement body 3 and the other end extends into the planting groove 5. The diversion grooves 4 on the surface of the slope reinforcement body 3 are connected to each other, and together form a dense diversion network. In the process of rainwater flowing downward, since the diversion groove 4 is connected to the planting groove 5, and the groove of the planting groove 5 is a groove structure with an inward guide angle, after the water flows into the planting groove 5, when the rainwater in the planting groove 5 overflows, it is discharged downward from the diversion groove 4, thereby improving the rainwater storage capacity. The diversion groove 4 is provided with;

[0025] The side of the slope protection reinforcement body 3 is staggered with a plurality of matching limiting grooves 6 and a plurality of limiting blocks 7. The limiting blocks 7 are inserted into the limiting grooves 6 by the side of the slope protection reinforcement body 3 being arranged in a close fit, so that the slope protection reinforcement body 3 is laterally connected and locked, and the slope protection reinforcement body 3 is laterally connected, so that the slope protection reinforcement body 3 forms a complete structural network;

[0026] Furthermore, a corresponding number of anchor nails 8 are arranged on the corners of the slope protection reinforcement body 3, and the anchor nails 8 penetrate the integral bottom layer 1 and the felt cloth layer 2, so that the overall fixation of the slope protection reinforcement body 3 is achieved by penetrating the integral bottom layer 1 and the felt cloth layer 2 with the anchor nails 8.

[0027] The limit block 7 is specifically a steel bar card embedded in the slope protection reinforcement body 3, which not only strengthens the overall structural strength of the slope protection reinforcement body 3, but also realizes the function of limiting connection through the corresponding limit groove 6 and the limit block 7.

[0028] Furthermore, the slope protection reinforcement body 3 is specifically a hexagonal structured plate, and there are six guide grooves 4 on the surface of any corresponding slope protection reinforcement body 3. The hexagon has high stability and is also easy to install.

[0029] From the above, it can be generally known that the slope protection structure used in the water conservancy project adopts a porous composite slope protection structure.

A slope protection reinforcement body 3 connected into a network is arranged on the double bottom layer structure. The diversion groove 4 arranged on the slope protection reinforcement body 3 improves the interception effect of rainwater, ensuring that the moisture for the growth of green plants under the composite structure is fully guaranteed.
