[0032] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.
[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.
[0034] This application proposes a river channel concrete block assembly 10, which can be installed on the bank of the river channel to play a role in water retention, such as Figure 1 As shown, the river channel concrete block assembly 10 includes: a first concrete block 1, a second concrete block 2 and an upper cover 3.
[0035] The second concrete block 2 is stacked vertically with the first concrete block 1 to increase the vertical height of the river channel concrete block assembly 10. The second concrete block 2 is connected to the first concrete block 1 by snapping, which reduces the difficulty of connecting the second concrete block 2 and the first concrete block 1, thereby improving assembly efficiency. Of course, in some other implementations, the second concrete block 2 and the first concrete block 1 can also be connected by welding or bolting, which is not limited here.
[0036] The upper cover 3 is installed on the side of the second concrete block 2 away from the first concrete block 1, and the end of the upper cover 3 away from the second concrete block 2 is formed into a plane. During actual installation, the first concrete block 1 can be installed on the ground, and the second concrete block 2 and the upper cover 3 are stacked in sequence above the first concrete block 1. In this way, the upper cover 3 can protect the second concrete block 2 above the second concrete block 2, and the end face of the upper cover 3 away from the second concrete block 2 is a plane to avoid scratches caused by people touching the upper cover 3.
[0037] It should be noted that the above-mentioned first building blocks and second building blocks can be used in any combination and are not limited to the illustrations shown in the accompanying drawings. Building blocks of different numbers or lengths can be selected for adjustment according to actual needs; different building blocks, including the longest and the shortest, etc., only differ in length, and the structure can be exactly the same; the order of the first building block and the second building block is not limited. For example, the first building block can also be the second building block, and the second building block can also be the first building block.
[0038] For example, Figure 1 As shown, in a first direction perpendicular to the vertical direction, the outer end 102 of the first concrete block 1 is flush with the outer end 202 of the second concrete block 2, and the inner end 101 of the first concrete block 1 protrudes beyond the inner end 201 of the second concrete block 2, so that the inner end 101 of the first concrete block 1 and the inner end 201 of the second concrete block 2 form a first step structure. In other words, in the first direction, the length of the second concrete block 2 is shorter than the length of the first concrete block 1.
[0039] It can be understood that the inner end 101 of the first concrete block 1 refers to the end of the first concrete block 1 facing the water in the river channel, the outer end 102 of the first concrete block 1 refers to the end of the first concrete block 1 away from the water in the river channel, the inner end 201 of the second concrete block 2 refers to the end of the second concrete block 2 facing the water in the river channel, and the outer end 202 of the second concrete block 2 refers to the end of the second concrete block 2 away from the water in the river channel.
[0040] Therefore, by setting the outer end 102 of the first concrete block 1 flush with the outer end 202 of the second concrete block 2, the workmanship of the river channel concrete block assembly 10 is improved, and by setting the inner end 101 of the first concrete block 1 and the inner end 201 of the second concrete block 2 to form a first step structure, when the water in the river channel hits the river channel concrete block assembly 10, the water flow will hit the first step structure. In this way, the first step structure can play a certain buffering role on the impact of the water in the river channel, thereby improving the water-retaining capacity of the river channel concrete block assembly 10.
[0041] According to the river channel concrete block assembly 10 of the embodiment of the present application, the second concrete block 2 is arranged to overlap with the first concrete block 1 in the vertical direction, and the upper cover 3 is installed on the side of the second concrete block 2 away from the first concrete block 1 to form the river channel concrete block assembly 10, and the second concrete block 2 is connected to the first concrete block 1 by clipping, so as to reduce the difficulty of setting up the river channel embankment. At the same time, in the first direction perpendicular to the vertical direction, the outer end 102 of the first concrete block 1 is flush with the outer end 202 of the second concrete block 2, and the inner end 101 of the first concrete block 1 protrudes from the inner end 201 of the second concrete block 2 so that the inner end 101 of the first concrete block 1 and the inner end 201 of the second concrete block 2 form a first step structure. In this way, the first step structure can play a certain buffering role on the impact of water in the river channel, thereby improving the water retaining capacity of the river channel concrete block assembly 10.
[0042] In some embodiments, the river channel concrete block assembly 10 also includes a cement layer or a concrete layer (not shown in the figure). The cement or concrete can be poured on the outside of the first concrete block 1, the second concrete block 2 and the upper cover 3 to form a cement layer or a concrete layer, thereby enhancing the waterproof ability and structural strength of the river channel concrete block assembly 10.
[0043] In some embodiments, the second concrete block 2 includes at least one sub-concrete block 20. In the vertical direction, if it contains multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction are gradually decreasing, gradually increasing, uniform in length, or irregularly arranged in length.
[0044] For example, in the vertical direction, if there are multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction are gradually reduced, so that a step structure can be formed between two adjacent sub-concrete blocks 20 in the vertical direction. In this way, the step structure can be used to buffer the impact of water in the river channel, thereby improving the water-retaining capacity of the river channel concrete block assembly.
[0045] Alternatively, in the vertical direction, if there are multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction gradually increase, so that a step structure can be formed between two adjacent sub-concrete blocks 20 in the vertical direction. In this way, the step structure can be used to buffer the impact of water in the river channel, thereby improving the water-retaining capacity of the river channel concrete block assembly.
[0046] Alternatively, in the vertical direction, if there are multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction are consistent, so that the specifications of the multiple sub-concrete blocks 20 are the same, which facilitates unified production and reduces production difficulty.
[0047] Alternatively, in the vertical direction, if there are multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction are irregularly arranged, so that the specifications of the multiple sub-concrete blocks 20 are different. In this way, sub-concrete blocks 20 of different specifications can be randomly installed to improve assembly efficiency.
[0048] In some embodiments, if there are multiple sub-concrete blocks 20, the multiple sub-concrete blocks 20 are stacked in sequence, and the lengths of the multiple sub-concrete blocks 20 in the first direction gradually decrease so that the inner ends of two adjacent sub-concrete blocks 20 form a second step structure.
[0049] Therefore, by setting multiple sub-concrete blocks 20 with their lengths in the first direction gradually decreasing, so that the inner ends of two adjacent sub-concrete blocks 20 form a step structure, the second step structure can play a certain buffering role on the impact of water in the river channel, thereby improving the water-retaining capacity of the river channel concrete block assembly 10.
[0050] Furthermore, in the vertical direction, any two adjacent sub-concrete blocks 20 are connected by snapping. This reduces the difficulty of connecting the two adjacent sub-concrete blocks 20 and helps improve assembly efficiency. Of course, in some other implementations, the two adjacent sub-concrete blocks 20 can also be connected by welding or bolting, which is not limited here.
[0051] In some embodiments, as Figure 3 As shown, the first concrete block 1 is provided with a first energy absorbing cavity 15. Figure 4 As shown, the second concrete block 2 is provided with a second energy absorbing cavity 25 .
[0052] Therefore, by setting the first energy absorption cavity 15 and the second energy absorption cavity 25, the first energy absorption cavity 15 and the second energy absorption cavity 25 can be used to absorb energy, so that when the water in the river channel hits the river channel concrete block assembly 10, part of the impact energy can be absorbed by the first energy absorption cavity 15 and the second energy absorption cavity 25, thereby avoiding damage to the river channel concrete block assembly 10 and improving the water-retaining capacity of the river channel concrete block assembly 10.
[0053] Among them, if the lengths of multiple sub-concrete blocks 20 in the first direction gradually decrease, then in the first direction, the number of first energy absorption cavities 15 is greater than the number of second energy absorption cavities 25. It can be understood that the more energy absorption cavities there are, the better the energy absorption effect. Therefore, the energy absorption effect of the first concrete block 1 is better than that of the second concrete block 2, so as to adapt to the impact force of the water in the river channel on the river channel concrete block assemblies 10 at different heights.
[0054] In some embodiments, as Figure 2 As shown, in the second direction, the first concrete blocks 1 are provided with a plurality of first concrete blocks 1, and any two adjacent first concrete blocks 1 and a second concrete block 2 (such as Figure 1 The second concrete block 2) shown in the figure is connected by snapping, and the second direction and the first direction are located in the same horizontal plane, and the second direction is perpendicular to the first direction.
[0055] Thus, one second concrete block 2 can be used to fix two adjacent first concrete blocks 1 in the second direction, thereby making the arrangement of the first concrete blocks 1 and the second concrete blocks 2 more compact and improving assembly efficiency.
[0056] In some embodiments, the inner end 101 of the first concrete block 1 and / or the inner end 201 of the second concrete block 2 is provided with a first convex surface 41 .
[0057] It can be understood that the inner end 101 of the first concrete block 1 refers to the end of the first concrete block 1 facing the water in the river channel, and the inner end 201 of the second concrete block 2 refers to the end of the second concrete block 2 facing the water in the river channel.
[0058] For example Figure 3As shown, the inner end 101 of the first concrete block 1 is provided with a first convex surface 41 , so that when the water flow in the river channel impacts the inner end 101 of the first concrete block 1 , the first convex surface 41 can play a buffering role.
[0059] Or as Figure 4-Figure 6 As shown, the inner end 201 of the second concrete block 2 is provided with a first convex surface 41 , so that when the water flow in the river channel impacts the inner end 201 of the second concrete block 2 , the first convex surface 41 can play a buffering role.
[0060] Alternatively, the inner end 101 of the first concrete block 1 and the inner end 201 of the second concrete block 2 are both provided with a first convex surface 41. Thus, when the water flow in the river channel impacts the inner end 101 of the first concrete block 1 and the inner end 201 of the second concrete block 2, the first convex surface 41 can play a buffering role.
[0061] In some embodiments, the outer end 102 of the first concrete block 1 and / or the outer end 202 of the second concrete block 2 is provided with a second convex surface 42 .
[0062] It can be understood that the outer end 102 of the first concrete block 1 refers to the end of the first concrete block 1 away from the water in the river channel, and the outer end 202 of the second concrete block 2 refers to the end of the second concrete block 2 away from the water in the river channel.
[0063] For example Figure 3 As shown, the outer end 102 of the first concrete block 1 is provided with a second convex surface 42, or as shown in FIG. Figure 4-Figure 6 As shown, the outer end 202 of the second concrete block 2 is provided with a second convex surface 42, or the outer end 102 of the first concrete block 1 and the outer end 202 of the second concrete block 2 are both provided with a second convex surface 42, thereby making the outer end 202 of the first concrete block 1 and / or the second concrete block 2 more smooth and avoiding scratches.
[0064] In some embodiments, in a first direction, such as Figure 1 and Figure 7 As shown, the inner end of the upper cover 3 is provided with a chamfer 30 .
[0065] It can be understood that the inner end of the upper cover 3 refers to the end of the upper cover 3 facing the water in the river channel. Therefore, when the water flow in the river channel hits the inner end of the upper cover 3, the chamfer 30 can play a buffering role.
[0066] In some embodiments, the first concrete block 1 includes a first base 11 and a first boss 12. In the vertical direction, the first boss 12 protrudes from the first base 11, and the projection of the first boss 12 falls inside the projection of the first base 11. Thus, the height of the first concrete block 1 can be increased by the first boss 12, and the projection of the first boss 12 falls inside the projection of the first base 11, so that the provision of the first boss 12 does not affect the length or width of the first base 11.
[0067] In some embodiments, the first boss 12 is provided with a plurality of engaging protrusions for engaging with the second concrete block 2, and the plurality of engaging protrusions are spaced apart along the circumference of the boss. Thus, the engagement stability of the first concrete block 1 and the second concrete block 2 can be enhanced by the plurality of engaging protrusions spaced apart along the circumference of the boss.
[0068] The following is combined with Figure 1 An embodiment of the river channel concrete block assembly 10 of the present application is described as follows:
[0069] The river channel concrete block assembly 10 includes a plurality of first concrete blocks 1, a plurality of second concrete blocks 2 and a plurality of upper covers 3. In the vertical direction, the second concrete blocks 2 are stacked on top of the first concrete blocks 1, and the upper covers 3 are stacked on top of the second concrete blocks 2.
[0070] The first concrete block 1 is provided with a first energy absorbing cavity 15 and includes a first base 11 and a first boss 12 . The first base 11 is provided with a first clamping groove 14 . The first boss 12 is connected to the first base 11 and is provided with a first clamping protrusion 13 .
[0071] Furthermore, the first concrete block 1 may be provided with multiple layers. For example, the first concrete block 1 is provided with two layers. The two layers of first concrete blocks 1 are stacked in the vertical direction, and in two first concrete blocks 1 adjacent in the vertical direction, the first clamping protrusion 13 of one first concrete block 1 is clamped and matched with the first clamping groove 14 of the other first concrete block 1.
[0072] The second concrete block 2 includes three sub-concrete blocks 20, which are a first sub-concrete block 20A, a second sub-concrete block 20B and a third sub-concrete block 20C. In the first direction, the lengths of the first sub-concrete block 20A, the second sub-concrete block 20B and the third sub-concrete block 20C decrease successively, and any one of the first sub-concrete block 20A, the second sub-concrete block 20B and the third sub-concrete block 20C is provided with a second energy absorbing cavity 25 and includes a second base 21 and a second boss 22, the second base 21 is provided with a second clamping groove 24, and the second boss 22 is connected to the second base 21 and is provided with a second clamping protrusion 23.
[0073] During actual assembly, the first sub-concrete block 20A, the second sub-concrete block 20B and the third sub-concrete block 20C are stacked in sequence above the first concrete block 1 located on the upper layer, wherein the second clamping groove of the first sub-concrete block 20A is clamped with the first clamping protrusion 13 of the first concrete block 1 located on the upper layer, the second clamping protrusion 23 of the first sub-concrete block 20A is clamped with the second clamping groove 24 of the second sub-concrete block 20B, and the second clamping groove 24 of the third sub-concrete block 20C is clamped with the second clamping protrusion 23 of the second sub-concrete block 20B.
[0074] Furthermore, the upper cover 3 is provided with a third engaging groove, and the third engaging groove is engaged with the second engaging protrusion 23 of the third sub-concrete block 20C.
[0075] In the first direction, one end of the first concrete block 1, the first sub-concrete block 20A, the second sub-concrete block 20B, and the third sub-concrete block 20C are flush, and the other ends are formed into a stepped shape. In this way, the stepped structure can provide a certain buffering effect on the impact of water in the river channel, thereby improving the water-retaining capacity of the river channel concrete block assembly 10.
