Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of retaining walls, in particular to a retaining wall structure for river slopes. Background Art
[0002] During river channel construction, retaining walls are usually set up on the river slopes to prevent soil erosion and protect the stability of the riverbank structure.
[0003] Traditional retaining wall structures mainly adopt two forms: one is a solid retaining wall made of concrete, and the other is a prefabricated retaining wall made of hollow bricks. Among them, the retaining wall cast in concrete has high strength and stability due to its material characteristics, which can effectively resist the impact of water flow and soil pressure, and ensure the stability and safety of the slope. However, the construction of a retaining wall cast in concrete requires a long construction period. On the other hand, a retaining wall made of hollow bricks has obvious construction advantages. Because these bricks are usually pre-manufactured in factories, only simple assembly work is required at the construction site, thus shortening the construction period. However, the overall strength of this type of retaining wall is relatively low, and it is prone to deformation or even collapse when facing large water pressure or external force, thereby affecting its long-term performance and safety reliability. In view of the above problems, the utility model proposes a retaining wall structure for river slopes that is easy to construct and has high overall strength. Utility Model Content
[0004] The utility model aims to provide a retaining wall structure for river slope, which is used to solve the problems raised in the above-mentioned background technology.
[0005] The utility model is realized by the following technical solutions:

[0020] 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.
[0021] Example: See Figures 1 to 3 According to an embodiment of the utility model, a retaining wall structure for a river slope is provided, which is used to be set up on a slope 6 of a river channel 1, and includes a plurality of prefabricated retaining units 2 arranged on the slope 6 in an overlapping manner, each retaining unit 2 includes a main body 20, an upper plate body 21 and a lower plate body 22 respectively fixed vertically to the upper and lower surfaces of the main body 20, and a side plate body 23 fixed vertically to the front end of the main body 20, the upper plate body 21 is located directly above the lower plate body 22, and when two adjacent retaining units 2 are overlapped with each other, the front side plate of one retaining unit 2 abuts against the front side of the upper plate body 21 of the other retaining unit 2, and its lower plate body 22 abuts against the rear end of the main body 20 of the other retaining unit 2.
[0022] In the retaining wall structure for river slopes adopting the above-mentioned structure, when the upper and lower retaining units 2 are overlapped together, the upper plate body 21 of the retaining unit 2 located at the lower layer limits the backward movement of the retaining unit 2 located at the upper layer, and the main plate body 20 of the retaining unit 2 located at the lower layer limits the forward movement of the retaining unit 2 located at the upper layer, thereby effectively limiting the forward and backward movement of the retaining unit 2 located at the upper layer. Therefore, the retaining wall structure formed by overlapping the retaining units 2 using the above-mentioned structure is not only easy to assemble, but also has greatly improved strength after assembly compared to the retaining wall formed by stacking hollow bricks in the prior art.
[0023] In this exemplary embodiment, the height of the side plate 23 protruding from the lower surface of the main plate 20 is consistent with the height of the lower plate 22. This arrangement can increase the vertical support area between adjacent retaining units 2, thereby reducing the probability of the retaining unit 2 being damaged by pressure.
[0024] In this exemplary embodiment, the main body 20, the upper plate 21 and the side plate 23 enclose a planting groove 3 with an open top. In this way, green plants can be cultivated after filling a proper amount of soil in the planting groove 3, which is conducive to maintaining the ecological environment of the river 1.
[0025] In this exemplary embodiment, when adjacent retaining units 2 overlap each other, a hiding cavity 4 is formed therebetween. The side plates 23 and the upper plates 21 of the retaining units 2 are both provided with through holes 24. The through holes 24 of the side plates 23 and the through holes 24 of the upper plates 21 overlap each other when adjacent retaining units 2 overlap each other, and form an inlet and outlet passage connecting the hiding cavity 4 and the planting trough 3. With such a configuration, amphibians in the river channel 1 can freely enter and exit the hiding cavity 4 through the inlet and outlet passage. The configuration of the hiding cavity 4 provides a living place for amphibians to avoid natural enemies. The existence of the hiding cavity 4 not only provides protection for amphibians, but also may attract other small wild animals to come and live, thereby promoting the increase of biodiversity in the river channel 1.
[0026] In this exemplary embodiment, a group of retaining units 2 is respectively arranged on the slopes 6 on both sides of the river channel 1, and the two groups of retaining units 2 form two retaining walls on the slopes 6 on both sides of the river channel 1. A bottom plate 5 is arranged at the bottom of the river channel 1, and the two ends of the bottom plate 5 are respectively abutted against the retaining units 2 at the bottom of the two retaining walls. Specifically, the bottom of the side plate body 23 of the retaining unit 2 abuts against the upper surface of the bottom plate 5, and the end surface of the bottom plate 5 abuts against the front side of the lower plate body 22 of the retaining unit 2. In this arrangement, the two retaining walls located on both sides of the river channel 1 are supported by the bottom plate 5, which can further improve the overall strength of the retaining wall, prevent the retaining wall from sliding down, and extend the service life of the retaining wall.
[0027] Working principle: first, a bottom plate 5 is laid at the bottom of the river channel 1. The bottom plate 5 can be a precast concrete plate. Then, two retaining walls are formed on both sides of the river channel 1 by overlapping a number of retaining units 2. When the upper and lower retaining units 2 are overlapped together, the upper plate body 21 of the retaining unit 2 at the lower layer limits the backward movement of the retaining unit 2 at the upper layer, and the main plate body 20 of the retaining unit 2 at the lower layer limits the forward movement of the retaining unit 2 at the upper layer, thereby effectively limiting the forward and backward movement of the retaining unit 2 at the upper layer. The retaining wall structure formed in this way is not only easy to assemble, but also has greatly improved strength after assembly.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
