Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a permeable brick used for a permeable dam and a permeable dam. Background Art

[0002] A dam is a hydraulic structure used to store water to prevent drought, irrigate farmland, and release floodwaters when necessary. It is a basic water conservancy engineering structure.

[0003] Since the water quality of rivers is generally poor during the dry season, the nitrogen and phosphorus content is higher than that during the flood season, and eutrophication of water bodies is prone to occur. In order to improve the eutrophication of water bodies, the application of permeable dams has become more and more common in recent years. Permeable dams are a kind of light-weight drainage structure that allows part of the water flow to pass through the dam body, which can intercept runoff and purify water bodies.

[0004] Permeable dams are usually constructed using natural sand and gravel particles and are formed through artificial stacking or mechanical compaction. Their ability to purify water is not ideal, and the dam structure is easily damaged during long-term water scouring.

[0005] Permeable bricks are an environmentally friendly building material that uses the pore structure of the brick body itself to allow water to penetrate through, and have high permeability. If permeable bricks are laid on a permeable dam, the problem of the dam structure being damaged by water scouring can be improved without affecting the permeability of the permeable dam. However, since permeable bricks do not have the ability to purify water, the problem of the permeable dam's unsatisfactory water purification ability remains unsolved. Based on this, a permeable brick with water purification ability is designed to improve the water purification ability of the permeable dam when it is applied to the permeable dam, which is of great significance for improving the water quality of the water body.

[0017] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 1. The permeable bricks used for the permeable dam of the present application are provided with an adsorption component in the brick body. The pollutants contained in the water passing through the brick body are adsorbed by the adsorption component, so that the pollutant content in the water body after passing through the permeable brick is reduced, and the nitrogen and phosphorus pollutant content and organic pollutant content in the water body are reduced, so that the permeable bricks have a higher water purification effect. When the permeable bricks are laid on the permeable dam, the permeable bricks are used to cover the surface of the permeable dam to prevent the water body from directly scouring the permeable dam body, so that the permeable bricks can improve the problem of the dam body structure being damaged by the scouring of the water body. And because of the permeable function of the permeable bricks, the permeable function of the permeable dam is not affected, and the higher water purification capacity of the permeable bricks can be used to make the permeable dam have a higher water purification capacity, thereby improving the water quality of the water body and improving the environmental quality.

[0018] 2. The permeable brick of the present application includes two main parts, and the two main parts can be connected by the cooperation of a splicing groove and a splicing strip. In actual application, among the multiple brick bodies, multiple main parts with splicing strips and multiple main parts with splicing grooves are staggered in the direction of the length of the second side, and the adjacent main parts with splicing strips and main parts with splicing grooves are connected by the splicing strips and the splicing grooves. In this way, the multiple brick bodies are restricted from relative movement in the direction of the length of the second side to form a strip-shaped paving unit, and multiple paving units are laid in sequence in the direction of the first length, so as to form a permeable paving covering the paved structural surface. It has the advantages of simple structure and convenient paving, and when the main part needs to be replaced, the main part can be directly lifted in a direction perpendicular to the paved structural surface, and the maintenance of the permeable paving is also simpler.

[0020] 4. The permeable dam of the present application is paved with permeable bricks with adsorption components on the dam body, and the permeable bricks are used to cover the surface of the permeable dam to prevent the water body from directly scouring the permeable dam body, thereby improving the problem of the dam body structure being damaged by water scouring. And because of the permeable function of the permeable bricks, it does not affect the permeable function of the permeable dam, and the higher water purification capacity of the permeable bricks can make the permeable dam have a higher water purification capacity, thereby improving the water quality of the water body and improving the environmental quality.

[0021] 5.

[0030] Reference Figure 1-4 As shown, an embodiment of the present application provides a permeable dam, which includes a permeable dam body 3 and a permeable pavement 4 laid on the surface of the dam body 3, and the permeable pavement 4 includes a plurality of permeable bricks for the permeable dam.

[0031] Reference Figure 1 As shown, the dam body 3 includes a base 33, and 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 two adjacent areas are separated by a partition wall 35 connected to the base 33, and the partition wall 35 is provided with a permeable structure for water to pass through.

[0032] Among them, the base 33, as the foundation of the dam body 3, is constructed of permeable concrete, and can be designed as a reinforced concrete structure during design. The partition wall 35, as a partition component between two adjacent areas, 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 inlet 351 arranged at the bottom of the partition wall 35. The water on the water storage side of the dam body 3 can pass through multiple areas through the water inlet 351 and thus pass through 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. The dam body 3 has the ability to permeate and purify water quality. The permeable dam body 3 has a higher structural strength and is not easily damaged by water scouring.

[0033] 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 to be symmetrical on both sides in the width direction, with a single area in the middle, one or two areas or multiple areas on each side, and the particle size of the filter material 34 filled in each area gradually increases from the middle to the sides, and the figure is divided into five areas for illustration. When the dam body 3 of this structural form is adopted, the water storage side and the back water side surface of the dam body 3 are paved with permeable pavement 4, and the permeable pavement 4 covers the water storage side surface and the back water side surface of the permeable dam, so that the water body first passes through the permeable pavement 4, then passes through the dam body 3, and finally passes through the permeable pavement 4, so that the water body passing through the permeable dam is fully purified.

[0034] Or, if Figure 2 As shown, the dam body 3 can also be configured such that the particle size of the filter material 34 filled in each area from the water storage side to the back water side gradually decreases. When this structural form is adopted, a partition wall 35 is provided on the back water side of the dam body 3 to support the dam body 3 in the width direction, and the figure shows that it is divided into two areas. When the dam body 3 of this structural form is adopted, the permeable pavement 4 is laid only on the water storage side surface of the dam body 3, and the permeable pavement 4 covers the water storage side surface of the permeable dam.

[0035] Reference Figure 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.

[0036] Specifically, refer to Figure 3As shown, the acute angle formed between the water surface section 31 and the horizontal plane is 15-25°, and the acute angle formed between the water bottom section 32 and the horizontal plane is 40-60°, that is, the slope of the water surface section 31 is smaller than the slope of the water bottom section 32. In this embodiment, the acute angle formed between the water surface section 31 and the horizontal plane is 20°, and the acute angle formed between the water bottom section 32 and the horizontal plane is 45° for illustration. When designing, the height interval of the water surface section 31 is designed according to the change interval of the water level of the water body, so that the boundary between the water surface and the dam body 3 is always kept in the water surface section 31, the slope of the water surface section 31 is small, and the water surface section 31 of 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 absorb and intercept low-density pollutants such as grease, detergent paper scraps, etc. 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 to avoid accumulation on the dam body 3.

[0037] Reference Figure 4-6 As shown, in order to improve the water purification capacity of the permeable dam, the permeable brick used for the permeable dam includes a brick body 1 and an adsorption component 2 arranged in the brick body 1 for adsorbing pollutants in the water body.

[0038] Reference Figure 4 As shown, the brick body 1 includes two main body parts 11 in the form of columns, the bottom surface of the main body part 11 is a parallelogram and the side surface is perpendicular to the bottom surface, the two bottom surfaces of the main body part 11 include a splicing bottom surface 111, the splicing bottom surface 111 includes two mutually parallel first side edges 112 and two mutually parallel second side edges 113, and the two main body parts 11 are respectively provided with adsorption components 2. In one of the main body parts 11, the splicing bottom surface 111 is provided with two splicing grooves 114 extending along the length direction of the first side edge 112, and the two splicing grooves 114 are spaced apart along the length direction of the second side edge 113, and the adsorption component 2 on the main body part 11 is located between the two splicing grooves 114. In the other main body 11, a receiving groove 115 extending along the length direction of the first side edge 112 is provided on the splicing bottom surface 111, and the main body 11 forms splicing strips 116 extending along the length direction of the first side edge 112 on both sides of the receiving groove 115, respectively. The splicing strips 116 are used to be embedded in the splicing groove 114 and matched with the splicing groove 114, and the adsorption assembly 2 on the main body 11 is located in the receiving groove 115. It is suitable to be embedded in a splicing groove 114 on another main body 11 through a splicing strip 116 on one main body 11, so as to limit the relative movement of the two main bodies 11 along the length direction of the second side.

[0039] Reference Figure 4 and Figure 6As shown, specifically, the main body 11 is designed as a relatively low-height column, and the two main bodies 11 can be connected by the cooperation of a splicing groove 114 and a splicing strip 116. In actual application, among the multiple brick bodies 1, multiple main bodies 11 with splicing strips 116 and multiple main bodies 11 with splicing grooves 114 are staggered in the length direction of the second side 113, and the adjacent main bodies 11 with splicing strips 116 and main bodies 11 with splicing grooves 114 are connected by the splicing strips 116 and the splicing grooves 114. In this way, the multiple brick bodies 1 are restricted from relative movement in the length direction of the second side 113 to form a strip-shaped paving unit, and multiple paving units are laid in sequence in the first length direction, thereby forming a permeable pavement 4 covering the paved structural surface. The brick body 1 has the advantages of simple structure and convenient paving. When the main body 11 needs to be replaced, the main body 11 can be directly lifted in a direction perpendicular to the paved structural surface, and the maintenance of the permeable pavement 4 is also simpler.

[0040] Reference Figure 4 and Figure 6 As shown, further, in order to avoid relative movement between two adjacent paving units in the direction of the length of the second side 113, two limit blocks 12 are connected to the main body 11 with a splicing groove 114. The two limit blocks 12 are respectively located on both sides of the two second side edges 113 and outside the splicing bottom surface 111. The length of the limit block 12 in the direction of the length 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 limit block 12 in the height direction of the main body 11 are respectively flush with the two bottom surfaces of the main body 11. When paving permeable bricks, in one paving unit, two limit blocks 12 on each main body 11 with a splicing groove 114 are located on both sides of the paving unit, and the limit blocks 12 can be inserted between two splicing strips 116 of the main body 11 with a splicing strip 116 in the adjacent paving unit, and the two main bodies 11 with splicing grooves 114 connected by the main body 11 with a splicing strip 116 are in contact with the limit blocks 12, so that the relative movement of two adjacent splicing units in the length direction of the second side 113 is limited by the limit blocks 12. Thereby, the integrity of the permeable paving 4 formed by splicing a plurality of permeable bricks is improved.

[0041] Reference Figure 4-5 As shown, the adsorption component 2 includes a splicing block 21 and an adsorption layer 22, a filling groove 211 is provided in the splicing block 21, the adsorption layer 22 is filled in the filling groove 211, a main body 11 is provided with a splicing groove 114, the splicing block 21 is connected to the splicing bottom surface 111 and is located between two splicing grooves 114, and a main body 11 is provided with a 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.

[0042] Reference Figure 4-5As shown, specifically, in the splicing block 21 connected to the main body 11 provided with the splicing groove 114, the filling groove 211 is provided on a side surface where the splicing block 21 is connected to the splicing bottom surface 111, and the filling groove 211 is connected at both ends in the length direction of the first side 112; in the splicing block 21 connected to the main body 11 provided with the splicing strip 116, the filling groove 211 is provided on a side surface where the splicing block 21 is connected to the bottom surface of the splicing groove 114, and the filling groove 211 is connected at both ends in the length direction of the first side 112. The splicing block 21 can be directly placed on the main body 11, or bonded to the main body 11 by structural adhesive.

[0043] When designing the filling groove 211, the projection of the filling groove 211 on the joint bottom surface 111 has a larger area to increase the contact area between the adsorption layer 22 filled in the filling groove 211 and the water passing through the permeable bricks, thereby improving the water purification effect.

[0044] Reference Figure 7 As shown, further, in order to make the surface of the permeable pavement 4 formed by the splicing of the permeable bricks flat, when designing the thickness of the splicing block 21, the splicing strip 116 is embedded in the splicing groove 114, and the side of the splicing block 21 connected to the main body 11 with the splicing groove 114, away from the splicing bottom surface 111, is coplanar with the bottom surface of the main body 11 with the splicing strip 116 and opposite to the splicing bottom surface 111, and the side of the splicing block 21 connected to the main body 11 with the splicing strip 116, away from the bottom wall of the accommodating groove 115, is coplanar with the bottom surface of the main body 11 with the splicing groove 114 and opposite to the splicing bottom surface 111. Through this arrangement, the surface and bottom of the permeable pavement 4 formed by the splicing of the brick body 1 can be kept flat, so as to improve the overall structural stability and aesthetics.

[0045] Specifically, the adsorption layer 22 may be made of materials capable of purifying water, such as biochar, and a suitable material may be selected according to actual conditions.

[0046] This embodiment has the following advantages: 1. The permeable dam is composed of a base 3 constructed of permeable concrete and filter materials 34 in multiple areas, and permeable bricks are used to form a permeable pavement 4. On the premise of ensuring the permeability of the permeable dam, the structural strength of the permeable dam is improved, and the setting of the adsorption layer 22 in the permeable bricks can effectively improve the removal effect of soluble pollutants such as nitrogen and phosphorus, thereby improving the water purification effect of the permeable dam.

[0047] 2. The permeable bricks are spliced ​​and connected to each other, which can ensure the structural stability of the permeable pavement 4 without using cement, and can be more conveniently replaced to ensure the water purification effect, reduce the difficulty of maintenance, and save management and operation costs. The permeable bricks can be backwashed to restore the permeability, or the adsorption layer 22 can be replaced to restore the water purification capacity of the permeable bricks, which can be reused to save costs.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
