On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1:

[0034] As Figures 1 to 5 shown, this embodiment provides a river slope protection retaining wall, including a base platform 1, a third connecting support platform 2, a second connecting support platform 3, a first connecting support platform 4, positioning bolt rods 5, a base platform filling cavity 6, a first main card slot 7, a first sub-card slot 8, a second main card slot 9, a second sub-card slot 10, a third main card slot 11, and third sub-card slots 12 opened on both sides of the lower end of the outside of the first connecting support platform 4.

[0035] Among them, the base platform 1 serves as the retaining wall foundation for the construction and installation of the river slope protection. The front side of the base platform 1 is an inclined surface with an angle of 63.4° with the horizontal plane. For the right triangle constructed with this inclined surface as the hypotenuse, the ratio of the length of the right side at the rear to the right side at the bottom is 2:1, ensuring the soil stability of the river slope protection. A base platform filling cavity 6 is opened inside the base platform 1. The upper end and the rear side of the outside of the base platform 1 are both open. A number of uniformly distributed reinforcement anchor rods 13 are fixedly connected to the lower end of the outside of the base platform 1. By means of the reinforcement anchor rods 13, the friction between the base platform 1 and the river bottom is increased to prevent the soil slope from being squeezed and slipping. Moreover, a third connecting support platform 2 is provided on the upper side of the base platform 1. A second connecting support platform 3 is provided on the upper end of the outside of the third connecting support platform 2. A first connecting support platform 4 is provided on the upper side of the outside of the second connecting support platform 3. The number of connecting support platforms is adjusted by card disassembly according to the height of the retaining wall for slope protection set according to specific needs.

[0036] On both sides of the upper end of the outer part of the abutment 1, five first main card slots 7 are provided (five are taken as an example in this application). Correspondingly, five first sub-card slots 8 also need to be provided at the lower end of the outer part of the third connecting abutment 2. A second main card slot 9 is provided at the upper end of the outer part of the third connecting abutment 2 (three are taken as an example in this application). Three second sub-card slots 10 also need to be provided on both sides of the lower end of the outer part of the second connecting abutment 3. One third main card slot 11 is provided on both sides of the upper end of the outer part of the second connecting abutment 3. Similarly, one third sub-card slot 12 needs to be provided on both sides of the lower end of the outer part of the first connecting abutment 4. The corresponding main card slot and sub-card slot are aligned, and when put together, a hexagonal hole is formed. The included angle between the front and rear inclined planes and the upper and lower horizontal planes inside the main and sub-card slots is 116°. In this way, the inclined plane inside the card slot is a right triangle with the hypotenuse. The ratio of the right side of the front or rear side to the right side of the bottom is also 2:1. By arranging and stacking the three connecting abutments from bottom to top in the order from large to small, aligning the positive and negative card slots, after alignment, the positioning bolt rod 5 is inserted into the slot hole formed between the positive and negative card slots. Through the insertion of the positioning bolt rod 5, the inside of the positive and negative card slots is positioned, preventing the stacked connecting abutments and the connecting abutments and the abutment 1 from sliding back and forth due to the extrusion of the soil wall or river water.

[0037] In this way, when reducing the tendency of the connecting abutments and between the connecting abutments and the abutment 1 to slide back and forth and stagger, the extrusion of the front and rear side walls of the positive and negative card slots on the positioning bolt rod 5 can be reduced, and the risk of the positioning bolt rod 5 being squeezed and cut short can be reduced. The abutment 1 and the connecting abutment can be stacked and spliced along both sides of the river channel. For modular splicing construction, first place the abutment 1 well, fill the inside of the abutment filling cavity 6 inside the abutment 1 with sand to increase the self-weight of the abutment 1 and the downward pressure of the abutment 1. The surface is covered with concrete and is flush with the upper surface of the abutment 1, and it is ensured that the reinforcement anchor rod 13 at the lower end of the abutment 1 is inserted into the bottom of the river channel for fixation. Then place the third connecting abutment 2 on the upper surface of the abutment 1, and place them in sequence up to the uppermost first connecting abutment 4. Similarly, fill the inside of the connecting abutment with sand, and the surface is leveled with concrete. Anti-slip reinforcement is carried out through a number of uniformly distributed reinforcement card teeth 14 fixedly connected to the front side of the lower end of the connecting abutment.

[0038] After the connecting abutment and the abutment 1 are spliced together, a complete inclined plane is formed at the front side. Chamfering with an angle of 45° is made on both sides of the front end of the abutment 1 and both sides of the front end of the connecting abutment. In this way, during the process of splicing the stacked abutment 1 and connecting abutment along the river channel, a diversion groove 15 is formed by the chamfering between them, increasing the drainage efficiency of the roads on both sides of the river embankment.

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
