Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete bricks, and more specifically to a permeable concrete brick. Background Art
[0002] Permeable concrete is a honeycomb concrete made of aggregates, cement, reinforcing materials, admixtures and water of specific grade in specific proportions through a special molding process. It contains a large number of interpenetrating voids between the aggregate skeletons. In addition to the properties of general concrete, permeable concrete also has the following obvious advantages: when it rains, it can quickly infiltrate the surface of the ground, restore groundwater, and replenish groundwater well, solving the problem of large amounts of rainwater loss caused by impermeable concrete; at the same time, it can reduce runoff and water accumulation on the road surface on rainy days, and reduce the burden on urban road drainage facilities. Permeable concrete is in line with the trend of sponge cities advocated today, and is increasingly used in the field of urban construction.
[0003] In the actual use of existing concrete bricks, in order to ensure drainage, several drainage holes are usually opened throughout, and the moisture on the surface of the concrete bricks is quickly discharged to the ground through the drainage holes. However, the concrete bricks will become loose due to long-term use, and the looseness of a single brick will not be repaired separately or will not be repaired in time. When the concrete bricks are loose, gaps will be generated between the concrete bricks and the ground. When it rains, the bottom surface cannot quickly absorb rainwater, and water will accumulate in the gaps. When pedestrians step on them, the concrete bricks sink due to the looseness of the bricks, causing the accumulated water to spray out from the drainage holes opened on the surface of the concrete bricks. The sprayed accumulated water will affect pedestrians and pollute their clothes. A solution to the above problems is proposed below. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a permeable concrete brick, which can quickly drain the surface of the brick and avoid the spraying of accumulated water due to the shaking of the brick.
[0005] To solve the above problems, the utility model adopts the following technical solutions.
[0006] A permeable concrete brick comprises a brick body, wherein a plurality of protrusions are evenly arranged on the upper surface of the brick body, a guide groove is formed between two adjacent protrusions, a plurality of drainage ports are evenly arranged inside the plurality of guide grooves, and the plurality of drainage ports are vertically arranged. A buffer portion is provided at the bottom of the brick body, a buffer cavity is provided in the buffer portion, the drainage port runs through the upper surface of the brick body and the buffer portion, the bottom of the drainage port is connected with the buffer cavity, a plurality of water outlets are evenly provided at the bottom of the buffer cavity, the plurality of water outlets and drainage ports are staggered, and a plurality of support frames are evenly provided inside the buffer cavity for supporting the inside of the buffer cavity.
[0007] Preferably, a plurality of partitions are evenly arranged inside the buffer cavity, the partitions are fixedly connected to the buffer cavity, the partitions divide the buffer cavity into a plurality of buffer chambers, a plurality of water holes are evenly opened on the partitions, and the water holes on two adjacent partitions do not correspond.
[0008] Preferably, the opening at one end of the drain outlet located inside the guide groove is trumpet-shaped.
[0009] Preferably, filter screens are evenly arranged inside the guide groove.
[0010] Preferably, baffles are staggeredly arranged inside the drain outlet, and the cross-section of the baffles is smaller than the cross-section of the drain outlet.
[0011] Preferably, the upper surface of the water outlet is bell-shaped.
[0012] Preferably, an auxiliary port for auxiliary drainage is opened on the side of the buffer cavity.
[0013] Compared with the prior art, the advantages of the present invention are:
[0014] 1. This solution forms a complete brick by combining a brick body and a buffer part, which plays a role in paving and supporting. The support frame inside the buffer cavity can improve the support of the buffer part, thereby improving the support strength. When liquid is spilled on the upper surface of the brick body, the liquid will flow into the guide groove. The liquid falls into the buffer cavity along the drainage port inside the guide groove under the action of its own gravity. The liquid entering the buffer cavity will be discharged into the ground through the water outlet inside the buffer cavity and absorbed by the ground. When a gap is formed between the ground and the buffer part and water accumulates, when pedestrians step on the surface of the brick body, the brick body will drive the buffer When the flushing part sinks, the accumulated water will enter the buffer cavity through the water outlet. The buffer cavity has a large space, which can buffer and collect the accumulated water passing through the water outlet. The buffer cavity needs to be filled before it can be sprayed out through the drain port. The water outlet and the drain port are staggered. When the accumulated water passes through the water outlet, it will act on the position of the upper surface of the buffer cavity that is not the drain port, and then fall into the buffer cavity. This can prevent the accumulated water from directly passing through the drain port when it is sprayed out from the water outlet in the reverse direction, thereby playing a protective role. When pedestrians walk by, the brick body and the buffer part are reset, and the accumulated water inside the buffer cavity can be discharged through the water outlet again.
[0015] Second, the partition serves to hinder the accumulated water from being sprayed into the buffer chamber through the water outlet, thereby reducing the impact force of the accumulated water sprayed through the water outlet, reducing the kinetic energy, and reducing the amount of accumulated water splashed through the drain outlet. The strength can also be improved by the partition.
[0016] 3. The drain outlet is located at one end of the guide groove and is trumpet-shaped, which can effectively improve the efficiency of discharging the accumulated water inside the guide groove through the guide groove, and can reduce the ejection speed of the accumulated water through the drain outlet.
[0017] 4. The filter net can protect one end of the drain outlet inside the guide groove, prevent larger solid impurities from blocking one end of the drain outlet, and ensure the smooth flow of the drain outlet. At the same time, the impurities inside the guide groove can be removed by directly removing the filter net, which is convenient for subsequent cleaning work.
[0018] 5. The cross-section of the baffle is smaller than the cross-section of the drain outlet to ensure that the accumulated water flows to the buffer chamber through the guide groove, and the baffle can shield the drain outlet to prevent the accumulated water inside the buffer chamber from being sprayed through the drain outlet, so that the water inside the buffer chamber can only fill the buffer chamber and seep out.
[0019] 6. The upper surface of the water outlet is in the shape of a bell mouth, which can speed up the efficiency of discharging the accumulated water inside the buffer chamber, and at the same time reduce the initial velocity of the external accumulated water entering the buffer chamber through the water outlet, thereby reducing the splashing of the accumulated water.
[0020] 7. The auxiliary port can speed up the discharge of the accumulated water inside the buffer cavity. The auxiliary port is located on the side of the buffer chamber at the bottom, which can prevent the water seepage from directly bypassing the partition and ensure the buffering effect of the partition.

[0029] Embodiment 1:
[0030] See also Figure 1-6 A permeable concrete brick comprises a brick body 1, a buffer part 5 is arranged at the bottom of the brick body 1, the brick body 1 and the buffer part 5 constitute a complete brick, and the brick is a cube. The cube design is convenient for laying, has wide practicality, and plays a paving and supporting role. A plurality of protrusions 2 are evenly arranged on the upper surface of the brick body 1, and the protrusions 2 are arranged in an array along one direction. The upper surface of the protrusion 2 has a certain convex curvature, which can accelerate the flow of liquid into the guide groove 3. A guide groove 3 is formed between two adjacent protrusions 2. A plurality of drain ports 4 are evenly arranged inside the plurality of guide grooves 3, and the plurality of drain ports 4 are arranged vertically. The vertically arranged drain ports 4 can ensure the discharge efficiency of the accumulated water in the guide groove 3. The opening of one end of the drain port 4 located inside the guide groove 3 is trumpet-shaped. The drain port 4 is located at one end of the guide groove 3 and is trumpet-shaped, which can effectively improve the efficiency of the accumulated water in the guide groove 3 being discharged through the guide groove 3, and can reduce the ejection speed of the accumulated water through the drain port 4 by reverse osmosis.
[0031] When liquid is spilled on the upper surface of the brick body 1, the liquid will flow into the guide groove 3, and the liquid will flow along the drain port 4 inside the guide groove 3 under the action of its own gravity. At the same time, a filter screen 12 is evenly arranged inside the guide groove 3. The filter screen 12 can protect one end of the drain port 4 inside the guide groove 3, avoid large solid impurities from blocking one end of the drain port 4, and ensure the smooth flow of the drain port 4. At the same time, the impurities inside the guide groove 3 can be removed by directly removing the filter screen 12, which is convenient for subsequent cleaning work. Baffles 14 are staggered inside the drain port 4. The cross-section of the baffle 14 is smaller than the cross-section of the drain port 4. The cross-section of the baffle 14 is smaller than the cross-section of the drain port 4, which can ensure that the accumulated water flows to the buffer chamber 6 through the guide groove 3, and the baffle 14 can shield the drain port 4, avoid the accumulated water inside the buffer chamber 6 from being sprayed through the drain port 4, so that the water inside the buffer chamber 6 can only fill the buffer chamber 6 and seep out.
[0032] A buffer cavity 6 is provided in the buffer portion 5, and the drain port 4 runs through the brick body 1 and the upper surface of the buffer portion 5. The bottom of the drain port 4 is connected to the buffer cavity 6. A plurality of support frames 8 are evenly arranged inside the buffer cavity 6 to support the inside of the buffer cavity 6. The support frames 8 can improve the support of the buffer portion 5, thereby improving the support strength. A plurality of water outlets 7 are evenly provided at the bottom of the buffer cavity 6. The plurality of water outlets 7 and the drain port 4 are staggered. The staggered arrangement of the water outlets 7 and the drain port 4, when the accumulated water passes through the water outlets 7 in the reverse direction, will act on the position of the upper surface of the buffer cavity 6 other than the drain port 4, and then fall into the buffer cavity 6, which can prevent the accumulated water from directly passing through the drain port 4 when sprayed out from the water outlets 7, thereby playing a protective role.
[0033] The liquid entering the buffer chamber 6 will be discharged to the ground through the water outlet 7 inside the buffer chamber 6 and absorbed by the ground. The upper surface of the water outlet 7 is a bell-shaped mouth. The upper surface of the water outlet 7 is a bell-shaped mouth, which can speed up the efficiency of the accumulated water in the buffer chamber 6 to be discharged from the buffer chamber 6, and at the same time reduce the initial velocity of the external accumulated water entering the buffer chamber 6 through the water outlet 7, thereby reducing the splashing of the accumulated water.
[0034] A number of partitions 9 are evenly arranged inside the buffer cavity 6. The partitions 9 and the buffer cavity 6 are fixedly connected. The partitions 9 divide the buffer cavity 6 into a number of buffer chambers 10. A number of water holes 11 are evenly opened on the partitions 9, and the water holes 11 on two adjacent partitions 9 do not correspond. An auxiliary port 13 for auxiliary drainage is opened on the side of the buffer cavity 6, and the auxiliary port 13 is located on the side of the buffer chamber 10 at the bottom, which can prevent water seepage from the auxiliary port 13 from directly avoiding the partition 9, thereby ensuring the buffering effect of the partition 9. The auxiliary port 13 can speed up the discharge of accumulated water inside the buffer cavity 6.
[0035] The partition 9 serves to hinder the accumulated water from being sprayed into the buffer chamber 6 through the water outlet 7, thereby reducing the impact force of the accumulated water sprayed through the water outlet 7, reducing the kinetic energy, and reducing the amount of accumulated water splashed through the drain port 4. The partition 9 can also improve the overall strength.
[0036] Working principle:
[0037] When in use, the ground is leveled and supported by a number of brick bodies 1, and the support frame 8 inside the buffer cavity 6 can improve the support of the buffer part 5, thereby improving the support strength. When the liquid falls on the surface of the brick body 1, the liquid flows into the guide groove 3 under the action of its own gravity. The filter net 12 can protect one end of the drain outlet 4 inside the guide groove 3, avoiding large solid impurities from blocking one end of the drain outlet 4, thereby ensuring that the drain outlet 4 is unobstructed.
[0038] The liquid falls into the buffer chamber 6 along the drain port 4 inside the guide groove 3 under the action of its own gravity. The drain port 4 is located at one end of the guide groove 3 and is in a trumpet shape, which can effectively improve the efficiency of the accumulated water in the guide groove 3 being discharged through the guide groove 3. The cross-section of the baffle 14 is smaller than the cross-section of the drain port 4, which can ensure that the accumulated water flows through the guide groove 3 to the buffer chamber 6. The liquid entering the buffer chamber 6 will be discharged to the ground through the water outlet 7 inside the buffer chamber 6. The upper surface of the water outlet 7 is in a trumpet shape. On the one hand, it can speed up the efficiency of the accumulated water in the buffer chamber 6 being discharged from the buffer chamber 6. On the other hand, the auxiliary port 13 can speed up the discharge of the accumulated water in the buffer chamber 6 and absorb it through the ground.
[0039] When a gap is formed between the ground and the buffer part 5 and water accumulates, when pedestrians step on the surface of the brick body 1, the brick body 1 will drive the buffer part 5 to sink, and the accumulated water will enter the buffer chamber 6 through the water outlet 7. The trumpet design of the water outlet 7 can reduce the initial velocity of the external accumulated water entering the buffer chamber 6 through the water outlet 7, and reduce the splashing of the accumulated water. The partition 9 plays a blocking role when the accumulated water is sprayed into the buffer chamber 6 through the water outlet 7, thereby reducing the impact force of the accumulated water sprayed out through the water outlet 7, reducing the kinetic energy, and reducing the amount of accumulated water splashed out through the drain 4. The strength can also be improved by the partition 9.
[0040] In addition, the water outlet 7 and the drain port 4 are staggered, and when the accumulated water passes through the water outlet 7, it will act on the position of the upper surface of the buffer chamber 6 other than the drain port 4, and then fall into the buffer chamber 6, which can prevent the accumulated water from directly passing through the drain port 4 when it is reversely ejected from the water outlet 7, thereby playing a protective role. The buffer chamber 6 has a large space, which can buffer and collect the accumulated water passing through the water outlet 7. The buffer chamber 6 needs to be filled before it can be ejected through the drain port 4. The trumpet design of the drain port 4 can reduce the ejection speed of the accumulated water through the drain port 4 due to reverse osmosis. The baffle 14 can shield the drain port 4, preventing the accumulated water inside the buffer chamber 6 from being ejected through the drain port 4, so that the water inside the buffer chamber 6 can only fill the buffer chamber 6 and seep out.
[0041] When pedestrians pass by, the brick body 1 and the buffer part 5 are reset, and the accumulated water inside the buffer cavity 6 can be discharged through the water outlet 7 again.
