[0002] The water storage dam is a hydraulic structure used for water storage, drought prevention, farmland irrigation and flood discharge when necessary, and is a basic water conservancy project structure.

[0003] Because the water quality of rivers is poor in the dry season, the nitrogen and phosphorus content is higher than that in the wet season, and water body eutrophication is prone to occur. In recent years, the application of water-permeable dams is increasing, and the water-permeable dam is a light guide building that allows part of the water flow to pass through the dam body, which can play a role in retaining runoff and purifying water bodies.

If the water-permeable brick is laid on the water-permeable dam, the problem of damage to the dam structure due to water erosion can be improved without affecting the water permeability of the water-permeable dam, but the water purification capacity of the water-permeable dam is not ideal. Based on this, a water-permeable brick with water purification capacity is designed to improve the water purification capacity of the water-permeable dam when it is applied to the water-permeable dam, which is of great significance to improve the water quality of the water body.

[0047] Referring to Figures 1-4 As shown in the drawings, the embodiments of the present application provide a permeable dam, which comprises a permeable dam body 3 and a permeable pavement 4 laid on the surface of the dam body 3, the permeable pavement 4 comprising a plurality of permeable bricks for the permeable dam.

[0048] Referring to Figure 1 As shown in the drawings, the dam body 3 comprises a base 33, the upper part of the base 33 is divided into at least two areas along the width direction of the dam body 3, each area is filled with filter material 34, and the two adjacent areas are separated by a partition wall 35 connected with the base 33, and the partition wall 35 is provided with a permeable structure for water permeation.

[0049] Among them, the base 33 serves as the foundation of the dam body 3 and is constructed of permeable concrete. Specifically, it can be designed as a reinforced concrete structure during design. The partition wall 35 serves as a partition component between two adjacent areas and can be constructed of permeable concrete or ordinary concrete. When permeable concrete is used, it can be cast and formed integrally with the base 33, and when ordinary concrete is used, it can be cast and formed separately. The permeable structure on the partition wall 35 includes a water outlet 351 set at the bottom of the partition wall 35. Water from the water storage side of the dam body 3 can pass through the water outlet 351 and pass through multiple areas to penetrate the dam body 3. The filter material 34 is selected according to the actual design of the dam body 3, and filter materials 34 of different particle sizes can be filled in each area. This makes the dam body 3 permeable and water-purifying. The permeable dam body 3 has higher structural strength and is not easily damaged by water erosion.

[0050] Specifically, different structural forms are adopted according to different river channel dam bodies 3, such as Figure 1 As shown, the dam body 3 can be designed symmetrically across its width, with a single central region and one, two, or multiple regions on either side. The particle size of the filter media 34 within each region gradually increases from the center toward the sides, as illustrated in the figure by the five regions. When this structural form of the dam body 3 is employed, permeable pavement 4 is laid on both the water storage side and the backwater side of the dam body 3. The permeable pavement 4 covers both the water storage side and the backwater side of the permeable dam, ensuring that water first passes through the permeable pavement 4, then through the dam body 3, and finally through the permeable pavement 4, resulting in a fully purified water body.

[0051] Or, as Figure 2 As shown, the dam body 3 can also be configured so that the particle size of the filter material 34 gradually decreases in each area from the water storage side to the water storage side. When this structure is adopted, a partition wall 35 is provided on the water storage side of the dam body 3 to support the dam body 3 in the width direction, which is illustrated in the figure as divided into two areas. When using this structure, the permeable pavement 4 is laid only on the water storage side of the dam body 3, and the permeable pavement 4 covers the water storage side of the permeable dam.

[0052] Reference Figures 1-3 As shown, the water storage side surface of the dam body 3 is configured to include a water surface section 31 and a water bottom section 32 distributed up and down. The acute angle formed by the water surface section 31 and the horizontal plane is smaller than the acute angle formed by the water bottom section 32 and the horizontal plane, and the boundary between the water surface and the dam body 3 is located within the water surface section 31.

[0053] Specifically, refer to Figure 3As shown, the water surface section 31 forms an acute angle of 15-25° with the horizontal plane, and the water bottom section 32 forms an acute angle of 40-60° with the horizontal plane, i.e. the slope of the water surface section 31 is smaller than that of the water bottom section 32. In this embodiment, the water surface section 31 forms an acute angle of 20° with the horizontal plane, and the water bottom section 32 forms an acute angle of 45° with the horizontal plane. When designing, the height interval of the water surface section 31 is designed according to the change interval of the water level, so that the junction of the water surface and the dam body 3 is always kept within the water surface section 31. The water surface section 31 has a smaller slope, and the water surface section 31 on the surface layer of the dam body 3 has a larger contact area, so that the permeable bricks and the dam body 3 can more effectively adsorb and intercept pollutants such as oil, detergent paper scraps and the like with lower density. The water bottom section 32 is below the water surface, so that the objects intercepted by the dam body 3 roll to the bottom of the water under the action of gravity, avoiding accumulation on the dam body 3.

[0054] Referring to Figures 4-6 As shown, in order to improve the water quality purification capacity of the permeable dam, the permeable brick for the permeable dam comprises a brick body 1 and an adsorption assembly 2 arranged in the brick body 1 for adsorbing pollutants in the water body.

[0055] Referring to Figure 4 As shown, the brick body 1 comprises two main body parts 11 in the form of a cylinder, the bottom surface of the main body part 11 is a parallelogram and the side surface is perpendicular to the bottom surface, one of the two bottom surfaces of the main body part 11 comprises a splicing bottom surface 111, the splicing bottom surface 111 comprises two first side edges 112 parallel to each other and two second side edges 113 parallel to each other, and the adsorption assembly 2 is arranged on each of the two main body parts 11. In one of the two main body parts 11, two splicing grooves 114 extending along the length direction of the first side edge 112 are arranged on the splicing bottom surface 111, the two splicing grooves 114 are distributed at intervals along the length direction of the second side edge 113, and the adsorption assembly 2 on the main body part 11 is located between the two splicing grooves 114. In the other main body part 11, a containing groove 115 extending along the length direction of the first side edge 112 is arranged on the splicing bottom surface 111, and the main body part 11 forms a splicing strip 116 extending along the length direction of the first side edge 112 on both sides of the containing groove 115, the splicing strip 116 is used for being embedded in the splicing groove 114 and being matched with the splicing groove 114, and the adsorption assembly 2 on the main body part 11 is located in the containing groove 115. One splicing strip 116 on one main body part 11 is embedded in one splicing groove 114 on the other main body part 11, so as to limit the relative movement of the two main body parts 11 along the length direction of the second side edge.

[0056] Referring to Figure 4 and Figure 6As shown, in particular, the main body part 11 is designed as a low-height column, and the two main body parts 11 are connected by cooperation of a splicing groove 114 and a splicing strip 116. In actual application, in the plurality of brick bodies 1, the plurality of main body parts 11 provided with the splicing strip 116 and the plurality of main body parts 11 provided with the splicing groove 114 are staggered in the length direction of the second side edge 113, and the adjacent main body part 11 provided with the splicing strip 116 and the main body part 11 provided with the splicing groove 114 are connected by cooperation of the splicing strip 116 and the splicing groove 114, so that the plurality of brick bodies 1 are limited from relative movement in the length direction of the second side edge 113, forming a strip-shaped paving unit, and a plurality of paving units are sequentially laid in the first length direction, thereby forming the water-permeable pavement 4 covering the paved structure surface. The brick body 1 has the advantages of simple structure and convenient paving, and when the main body part 11 needs to be replaced, the main body part 11 can be directly lifted in the direction perpendicular to the paved structure surface, and the maintenance of the water-permeable pavement 4 is also simpler.

[0057] Referring to Figure 4 and Figure 6 As shown, further, in order to avoid relative movement of the two adjacent paving units in the length direction of the second side edge 113, the main body part 11 provided with the splicing groove 114 is connected with two limiting blocks 12, and the two limiting blocks 12 are located on the two sides of the two second side edges 113 and outside the splicing bottom surface 111. The length of the limiting block 12 in the length direction of the second side edge 113 is the same as the distance between the two splicing grooves 114, and the two side surfaces of the limiting block 12 in the height direction of the main body part 11 are flush with the two bottom surfaces of the main body part 11. In the paving of the water-permeable brick, in one paving unit, the two limiting blocks 12 on each main body part 11 provided with the splicing groove 114 are located on the two sides of the paving unit, and the limiting blocks 12 can be inserted between the two splicing strips 116 of the main body part 11 provided with the splicing strip 116 in the adjacent paving unit, and the two main body parts 11 provided with the splicing groove 114 connected with the main body part 11 provided with the splicing strip 116 are in contact with the limiting blocks 12, thereby limiting the relative movement of the two adjacent splicing units in the length direction of the second side edge 113 by the limiting blocks 12. Thus, the integrity of the water-permeable pavement 4 formed by the plurality of water-permeable bricks is improved.

[0058] Referring to Figures 4-5 As shown, the adsorption assembly 2 includes a splicing block 21 and an adsorption layer 22, the splicing block 21 is provided with a filling groove 211, and the adsorption layer 22 is filled in the filling groove 211. In the main body part 11 provided with the splicing groove 114, the splicing block 21 is connected to the splicing bottom surface 111 and located between the two splicing grooves 114. In the main body part 11 provided with the splicing strip 116, the splicing block 21 is located between the two splicing strips 116 and connected to the bottom wall of the accommodating groove 115.

[0059] Referring to Figures 4-5As shown, specifically, in the splicing block 21 connected to the main body part 11 provided with the splicing groove 114, the filling groove 211 is arranged on the side surface of the splicing block 21 connected with the splicing bottom surface 111, and the filling groove 211 penetrates through both ends in the length direction of the first side edge 112. In the splicing block 21 connected to the main body part 11 provided with the splicing strip 116, the filling groove 211 is arranged on the side surface of the splicing block 21 connected with the bottom surface of the splicing groove 114, and the filling groove 211 penetrates through both ends in the length direction of the first side edge 112. The splicing block 21 can be directly placed on the main body part 11 or adhered to the main body part 11 through structural glue.

[0060] In the design of the filling groove 211, the projection of the filling groove 211 on the splicing bottom surface 111 has a large area, so as to increase the contact area of the adsorption layer 22 filled in the filling groove 211 and the water passing through the water permeable brick, thereby improving the water purification effect.

[0061] Referring to Figure 7 As shown, further, in order to make the surface of the water permeable pavement 4 formed by splicing the water permeable bricks flat, in the design of the thickness of the splicing block 21, when the splicing strip 116 is embedded in the splicing groove 114, in the splicing block 21 connected to the main body part 11 provided with the splicing groove 114, the side surface away from the splicing bottom surface 111 is coplanar with the bottom surface of the main body part 11 provided with the splicing strip 116 and opposite to the splicing bottom surface 111. In the splicing block 21 connected to the main body part 11 provided with the splicing strip 116, the side surface away from the bottom wall of the accommodating groove 115 is coplanar with the bottom surface of the main body part 11 provided with the splicing groove 114 and opposite to the splicing bottom surface 111. Through the above setting, the surface and the bottom surface of the water permeable pavement 4 formed by splicing the brick bodies 1 can be kept flat, so as to improve the overall structural stability and aesthetic appearance.

[0062] Specifically, the adsorption layer 22 can adopt biological charcoal and other materials capable of purifying water quality, and the appropriate material can be selected according to the actual situation.

[0063] The embodiment has the following advantages:

[0064] 1. The water permeable dam is composed of a base 3 of water permeable concrete and a plurality of areas of filter material 34, and is paved with water permeable bricks to form a water permeable pavement 4. On the premise of ensuring the water permeability of the water permeable dam, the structural strength of the water permeable dam is improved, and the setting of the adsorption layer 22 in the water permeable brick can effectively improve the removal effect of soluble pollutants such as nitrogen and phosphorus, thereby improving the water purification effect of the water permeable dam.

[0065] 2. The permeable bricks are connected to each other, ensuring the structural stability of the permeable pavement 4 without the use of cement. This allows for easier replacement of permeable bricks, ensuring water purification, reducing maintenance and lowering management and maintenance costs. Furthermore, the permeable bricks can be backwashed to restore their permeability, or the adsorption layer 22 can be replaced to restore their water purification capacity, allowing for reuse and cost savings.
