Description

Technical Field

[0001] The present invention relates to the field of sponge city roads, in particular to a permeable brick structure for paving sponge city roads. Background Art

[0002] Sponge city is an urban stormwater management strategy and method, which means that the city ground can absorb rainwater like a sponge, store rainwater, and release it when needed.

[0003] In the current existing technology, the water absorption rate of floor tiles themselves is low and the water permeability is very poor, thus causing a large amount of rainwater to accumulate. When sponge cities are paving roads, in order to improve the water permeability of roads, the pavement of pedestrian roads is generally paved with permeable bricks. The permeable bricks have a porous structure inside, which can facilitate rainwater to quickly pass through the brick body and penetrate into the underground soil layer, thereby effectively reducing the situation of road surface water accumulation and reducing flood drainage pressure.

[0004] However, it takes a certain amount of time for rainwater to seep into the ground. When there is heavy rainfall in a short period of time, the rainfall amount is large in a short period of time, and the ground rainwater infiltration rate is lower than the rainfall rate, which leads to water accumulation on the road. Therefore, a permeable brick structure for sponge city road paving is proposed to address the above problem. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] Example 1

[0032] See also Figure 1-3As shown, a water-permeable brick structure for paving sponge city roads includes a base 11; the base 11 is provided with multiple; the top of the base 11 is slidably connected to a water-permeable brick body 12; the side of the base 11 is provided with a water collecting trough; the sides of the multiple bases 11 are provided with water tanks 13; the side of the water tank 13 close to the base 11 is fixedly connected with a connecting pipe 14; the connecting pipe 14 is inserted into the water collecting trough and slidably connected thereto; the top of the water tank 13 is slidably connected to a planting box 15; the bottom of the planting box 15 is fixedly connected to a group of cotton ropes; the top of the water tank 13 is provided with a water inlet; the water tank The side of 13 is hinged with a sealing cover 16; the sealing cover 16 is located on the side of the water inlet; the top of the water tank 13 is fixed with a drain pipe 17; the drain pipe 17 is provided with a water inlet; when paving, the two bases 11 are aligned and spliced together so that the water collection grooves on the sides of the two bases 11 form a trapezoidal groove, and then the permeable brick body 12 is placed on the top of the base 11, and then the above steps are repeated to pave the pedestrian walking road, and then the water tank 13 is buried on both sides of the road, and the connecting pipe 14 is inserted into the spliced water collection groove. The cross-section of the connecting pipe 14 is designed to be trapezoidal in shape, which is consistent with the shape of the water collection groove. The shape fits the road, and then the planting box 15 is placed on the top of the water tank 13. Some green plants will be planted on both sides of the road. The staff can plant green plants in the planting box 15. When the rainfall rate is low, rainwater will seep into the ground from the gap between the bases 11. When the rainfall is too heavy in a short time, the rainwater will pass through the seepage brick body 12 and then pass through the water collection tank. It will then be collected in the water tank 13 from the connecting pipe 14. The rainwater is collected and stored in the water tank 13. When it rains for a long time and in large quantities, the excess rainwater will enter the drain pipe 17 from the water inlet and then be discharged outward. During use, it can be The clean water at the bottom of the water tank 13 is absorbed and the rainwater is supplied to the plants in the planting box 15 through capillary action. At the same time, the staff can extract the water in the water tank 13 for use through the water intake. The sealing cover 16 is used to cover the water intake to reduce the evaporation of rainwater. Relying on the above-mentioned arrangement, the rainwater is collected in the water tank 13 for storage and used for plant growth, thereby improving the utilization rate of rainwater. When there is heavy rainfall in a short period of time, the rainwater that cannot infiltrate in a short time can be collected and stored through the water tank 13, thereby reducing the occurrence of waterlogging on the road. When the rainfall is too heavy, it can be discharged to the outside through the drain pipe 17.

[0033] Further, such as Figure 2 and Figure 3As shown, the bottom of the base 11 is provided with a groove; a permeable plate 22 is slidably connected in the groove; a water trough 21 is provided on the side of the base 11 away from the water collection tank; the water trough 21 and the groove are communicated with each other; a pipe body 23 is fixedly connected to the corresponding position of the drain pipe 17 and the water trough 21; the pipe body 23 passes through the wall of the water tank 13 and is fixed thereto; the end of the pipe body 23 is inserted into the water trough 21 and slidably connected thereto; when in use, the water trough 21 is located below the water collection tank, and excess rainwater will be injected into the pipe body 23 from the drain pipe 17, and then the pipe body 23 will inject the rainwater into the water trough 21 and the groove, and finally seep into the ground from the permeable plate 22. The permeable plate 22 is a porous structure, so that The remaining rainwater can seep into the ground to replenish the groundwater. During the paving process, in order to facilitate the smooth paving of the road, a layer of sand will be laid at the bottom of the base 11, and the permeable board 22 will be used to cover the layer of sand. This can reduce the flow of water and the loss of sand, which in turn causes holes to form at the bottom of the base 11. At the same time, the permeable board 22 can increase the area of ground seepage and reduce water accumulation. A pipe connected to the sewer is installed at the end of the drain pipe 17. The pipe is L-shaped. When the infiltration rate of the soil layer below the permeable board 22 is lower than the rainfall rate, the water level in the drain pipe 17 is higher, and the excess rainwater will be discharged into the sewer through the pipe connected to the sewer, thereby reducing the accumulation of water on the ground due to long-term heavy rainfall.

[0034] Further, such as Figure 4 and 5 As shown, the top inner wall of the water tank 13 is fixedly connected to a plate frame 31; the cross-section of the plate frame 31 is designed in a trapezoidal structure; a pair of filter plates 32 are bolted to the bottom of the plate frame 31; the filter plates 32 are arranged at an angle; the drain pipe 17 passes through the wall of the plate frame 31 and is fixed thereto; the water inlet is located in the middle of the plate frame 31; when the rainfall is large, the water flow scours the soil layer, resulting in a large amount of sediment in the water flow. The sediment and sediment will accumulate in the process of following the water flow, causing the pipe to be blocked. At the same time, the sediment will also It will clog the holes on the permeable plate 22 and affect its permeability. When the embodiment of the present invention is in use, the filter plate 32 is set to filter the water flow entering the drain pipe 17, reduce the sediment in the water flow, and thus reduce the blockage of the pipe and the permeable plate 22. At the same time, the filter plate 32 is set at an angle to reduce the accumulation of sediment on the filter plate 32. At the same time, when the rainfall is large, a water flow is formed in the water collection tank of the base 11, and the water flow can flush the sediment in the water collection tank and bring it into the water tank 13.

[0035] Further, such as Figure 1 and 4-8, a cleaning rack 48 is slidably connected to the side wall of the bottom of the plate frame 31; the cleaning rack 48 is located on the side of the filter plate (32); a brush plate 49 is provided on the cleaning rack 48; a connecting rod 47 is fixed to the side of the cleaning rack 48; a telescopic rod is fixed to the top of the connecting rod 47; a first rack 46 is fixed to the top of the telescopic rod; a guide slide is fixed to the side wall of the top of the plate frame 31; a second rack 471 is slidably connected in the guide slide; a first spring is fixed between the second rack 471 and the guide slide; a gear is rotatably connected to the side wall of the plate frame 31; the gear is located at the first A rack 46 is connected to a second rack 471; the second rack 471 and the gear are meshed with each other; a cylinder 41 is fixed to the side of the water tank 13; a bracket is fixed to the side of the cylinder 41; a fixed cylinder 42 is fixed to the middle of the bracket; a rotating shaft 43 is rotatably connected to the middle of the fixed cylinder 42; a fan blade is fixed to the surface of the rotating shaft 43; a crankshaft 44 is rotatably connected to the top of the water tank 13; a speed change mechanism is installed between the crankshaft 44 and the rotating shaft 43; a collar is rotatably connected to the surface of the crankshaft 44 corresponding to the second rack 471; the collar is fixed to the end of the second rack 471 There is a pull rope 45; a through hole is provided in the wall of the water tank 13; the pull rope 45 passes through the through hole; a connecting assembly is provided on the first rack 46; the connecting assembly is used to mesh the first rack 46 with the gear after the filter plate (32) is blocked, so that the brush plate 49 cleans the filter plate (32); when in use, strong winds will be accompanied by heavy rainfall, and the airflow will blow the fan blades to rotate, and the rotation of the fan blades will drive the rotating shaft 43 and the crank shaft 44 to rotate, and the rotation of the crank shaft 44 will pull the ring and the pull rope 45, and rely on the pull rope 45 to pull the second rack 471, the gear and the first rack 46 to rotate, thereby driving The connecting rod 47, the cleaning rack 48 and the brush plate 49 move, and the brush plate 49 moves on the plate frame 31 to brush the filter plate 32 and dredge the filter plate 32, thereby reducing the situation where a large amount of mud and sand completely clogs the filter plate 32, thereby reducing the situation where rainwater cannot be discharged due to the blockage of the filter plate 32, and then water accumulation occurs. When in use, the first spring is used to assist the second rack 471 to reset, and the speed change mechanism is decelerated through multiple internal reduction gears to increase the torque of the crank shaft 44, so that when the wind force is small, the wind drives the fan blades to drive the crank shaft 44 to rotate through the speed change mechanism.

[0036] Further, such as Figure 5As shown, the connecting assembly includes a sliding seat 51; the sliding seat 51 is slidably connected to the side wall of the plate frame 31; the first rack 46 is inserted into the sliding seat 51 and slidably connected thereto; the side of the sliding seat 51 is fixedly connected to a buoyancy frame; the top of the buoyancy frame is fixedly connected to a buoyancy cylinder 52; when in use, the brush plate 49 brushes the filter plate 32 for a long time and many times, which will cause the filter plate 32 to be quickly worn and then damaged. When the embodiment of the present invention is in use, when the filter plate 32 is blocked, the rainwater cannot be discharged, the water level of the rainwater will rise, and then the water level will drive the buoyancy cylinder 52 and the buoyancy frame to move upward through buoyancy, thereby driving the sliding seat 51 and the first rack. 46 meshes with the gear upward and stretches the telescopic rod, so that the rotation of the gear can drive the first rack 46 and the brush plate 49 to move. After the filter plate (32) is dredged, the water level drops, and then the first rack 46 and the sliding seat 51 are reset downward under the action of their own gravity, and then the first rack 46 is separated from the gear, thereby making the brush plate 49 lose its power source. Relying on the above arrangement, the brush plate 49 will only move when the water level of the water tank 13 is too high, thereby reducing the situation where the brush plate 49 moves back and forth and causes the filter plate 32 to be quickly worn. At the same time, it can reduce the situation where the brush plate 49 also moves and rubs the filter plate 32 in windy weather.

[0037] Further, such as Figure 6 As shown, a guide rod 62 is fixed to the top of the brush plate 49; the top of the guide rod 62 is rotatably connected to a pulley 63; a second spring is provided on the surface of the guide rod 62; a plurality of semicircular blocks 61 are fixed to the bottom side wall of the plate frame 31; the semicircular block 61 is located at the top of the pulley 63; in the process of the brush plate 49 moving and cleaning, the cleaning frame 48 will drive the guide rod 62 and the pulley 63 to move, and then the semicircular block 61 will squeeze the pulley 63 upward, and when the pulley 63 is separated from the semicircular block 61, the second spring will push the brush plate 49 to reset upward. By setting a plurality of semicircular blocks 61, the brush plate 49 can move back and forth up and down on the basis of horizontal movement, so that a cleaning friction force of different angles can be applied, thereby improving the cleaning effect and reducing cleaning dead corners.

[0038] Further, such as Figure 8As shown, a friction ring 71 is fixed to the middle of the fixed cylinder 42; a plurality of spring plates are fixed to the surface of the rotating shaft 43 in an array; an arc-shaped friction block 72 is fixed to the end of the spring plate away from the rotating shaft 43; a plurality of the arc-shaped friction blocks 72 are located in the middle of the friction ring 71; when the wind speed is high, the fan blades will be blown to rotate at a high speed, and their fast rotation speed will cause the pull rope 45 and the connecting rod 47 to bear too much load, thereby causing deformation. When the embodiment of the present invention is in use, the rotation of the rotating shaft 43 will drive the plurality of spring plates and the arc-shaped friction block 72 to rotate, and then rely on centrifugal force to make the arc-shaped friction force move away from the rotating shaft 43. When the rotating shaft 43 rotates rapidly, the surface of the arc-shaped friction block 72 contacts the inner wall of the friction ring 71, and relies on friction to decelerate the rotating shaft 43, thereby reducing the rotation speed of the rotating shaft 43, thereby reducing the situation where the pull rope 45 and the connecting rod 47 are damaged due to excessive rotation of the crank shaft 44.

[0039] Further, such as Figure 4 As shown, the bottom of the connecting pipe 14 is fixed with a separation pipe 81; the separation pipe 81 is located inside the water tank 13; the bottom of the separation pipe 81 is fixed with a sand discharge pipe; the bottom end of the sand discharge pipe is fixed with a vertical pipe 83; the bottom inner wall of the vertical pipe 83 is slidably connected with a collecting cylinder 82; the inner wall of the collecting cylinder 82 is fixed with a connecting rope; the top of the connecting rope is fixed with a top cover 84; the top cover 84 is located at the top of the vertical pipe 83; the vertical rod 92 passes through the bottom wall of the planting box 15 and is fixed thereto; the separation pipe 81 is a U-shaped pipe; when rainwater flows from the collection pipe into the water tank 13, the rainwater first enters the water tank 13, and the water flows into the water tank 13. After entering the separation pipe 81, it enters the water tank 13 from the top. The large particles of sediment in the rainwater will settle into the sand discharge pipe under the action of its own weight, and then enter the collection tube 82 for collection. After that, the large particles of sediment will enter the collection tube 82. Later, during daily maintenance, the staff can pull the top cover 84 and then take out the collection tube 82 through the connecting rope to take out the collected sediment. Relying on the above arrangement, it can collect a large amount of large particles of sediment contained in the rainwater for subsequent cleaning, thereby reducing the accumulation of a large amount of sediment in the water tank 13, which causes the capacity of the water tank 13 to decrease.

[0040] Further, such as Figure 3As shown, a plurality of slots 91 are provided at the bottom of the water collection trough; vertical rods 92 are slidably connected in the slots 91; a top plate 93 is fixedly connected to the top of the vertical rod 92; a bottom plate is fixedly connected to the bottom of the vertical rod 92; a card slot is provided at the top of the base 11; a connecting block 94 is slidably connected in the card slot; the connecting block 94 is designed as a U-shaped structure; when laying, the vertical rods 92 are inserted into the slots 91 of two adjacent bases 11, and the bottom plate is located at the connection point of the two adjacent bases 11, so as to connect the two bases 11, facilitate the mutual connection between multiple water collection troughs and water flow channels 21, and then the top plate 93 contacts the bottom side of the seepage brick body 12, so as to support the seepage brick body 12 and disperse the gravity borne by the top of the seepage brick body 12 to reduce its breakage. The connecting block 94 is used to clamp the two bases 11, splice and fix them, so that the base 11 is fixed on the permeable brick.

[0041] Example 2

[0042] like Figure 7 As shown, compared with Example 1, another embodiment of the present invention is: a cavity is opened at the top and bottom of the through hole; a roller 10 is rotatably connected in the cavity; the pull rope 45 is located between the two rollers 10; when in use, the roller 10 is arranged to contact the pull rope 45, so as to convert the sliding friction between the pull rope 45 and the through hole into rolling friction, thereby reducing the friction force and further reducing the wear on the pull rope 45.

[0043] Working principle: when laying, align and splice the two bases 11 together so that the water collection trough forms a trapezoidal trough, then place the seepage brick body 12 on the top of the base 11, and then repeat the above steps to pave the pedestrian road, and then bury the water tank 13 on both sides of the road, insert the connecting pipe 14 into the spliced water collection trough, and then place the planting box 15 on the top of the water tank 13, and then plant green plants in the planting box 15. When the rainfall rate is low, rainwater will seep into the ground from the gap between the bases 11. When the rainfall is too heavy in a short time, the rainwater will pass through the seepage brick body 12 and then pass through the water collection trough, and then collect in the water tank 13 from the connecting pipe 14. The rainwater is collected and stored in the water tank 13. When there is a lot of rainfall for a long time, Excess rainwater will enter the drain pipe 17 from the water inlet and then be discharged outwards. During use, the clean water at the bottom of the water tank 13 can be absorbed by the cotton rope, and the rainwater can be supplied to the plants in the planting box 15 through capillary action. At the same time, the staff can extract the water in the water tank 13 for use through the water intake. The sealing cover 16 is used to cover the water intake to reduce the evaporation of rainwater. Relying on the above-mentioned arrangement, the rainwater is collected in the water tank 13 for storage and used for plant growth, thereby improving the utilization rate of rainwater. When there is a short period of heavy rainfall, the rainwater that cannot infiltrate in a short time can be collected and stored through the water tank 13, thereby reducing the occurrence of waterlogging on the road. When the rainfall is too heavy, it can be discharged outwards through the drain pipe 17. Insert the vertical rod 92 into two adjacent The bottom plate is located at the connection point of two adjacent bases 11, thereby connecting the two bases 11, facilitating the mutual connection between multiple water collection tanks and water flow troughs 21, and then the top plate 93 contacts the bottom side of the seepage brick body 12, so as to support the seepage brick body 12 and disperse the gravity borne by the top of the seepage brick body 12 to reduce the occurrence of breakage. The connecting block 94 is used to clamp the two bases 11, splice and fix them, so that the base 11 is fixed on the permeable brick. When in use, excess rainwater will be injected into the pipe body 23 from the drain pipe 17, and then the pipe body 23 will inject the rainwater into the water flow trough 21 and the groove, and finally seep from the permeable plate 22 to the ground. The permeable plate 22 has a porous structure, so that excess Rainwater can seep down to replenish groundwater. During the paving process, in order to facilitate the smooth paving of the road, a layer of sand is laid at the bottom of the base 11, and the permeable plate 22 is used to cover the layer of sand. This can reduce the loss of sand caused by the flow of water, which in turn causes holes to form at the bottom of the base 11. At the same time, the permeable plate 22 can increase the area of ground water seepage and reduce water accumulation. When the rainfall is large, the water flow scours the soil layer, resulting in a large amount of sediment in the water flow. The sedimentation and accumulation of these sediments in the process of following the water flow will cause pipe blockage. At the same time, the sediment will also block the holes on the permeable plate 22, affecting its permeability. When the embodiment of the present invention is in use, the filter plate 32 can be set to filter the water flow entering the drain pipe 17.The filter plate 32 is tilted to reduce the accumulation of sediment on the filter plate 32. At the same time, when the rainfall is large, a water flow is formed in the water collection tank of the base 11, and the water flow can flush the sediment in the water collection tank and bring it into the water tank 13. When in use, strong winds will occur during heavy rainfall, and the air flow will blow the fan blades to rotate. The rotation of the fan blades will drive the rotating shaft 43 and the crank shaft 44 to rotate. The rotation of the crank shaft 44 will be driven by the pulling ring and the pull rope 45, and the pull rope 45 will pull the second rack 471, the gear and the first rack 46 to rotate, thereby driving the connecting rod 47, the cleaning frame 48 and the brush plate 49 to move, and the brush plate 49 will be driven on the plate The frame 31 moves upward to brush the filter plate 32 and dredge the filter plate 32, thereby reducing the situation where a large amount of sediment completely blocks the filter plate 32, thereby reducing the situation where rainwater cannot be discharged due to blockage of the filter plate 32, and then water accumulation occurs. When in use, the first spring is used to assist the second rack 471 to reset, and the speed change mechanism slows down through multiple internal reduction gears to increase the torque of the crankshaft 44. When the wind force is small, it can also drive the crankshaft 44 to rotate, and the brush plate 49 brushes the filter plate 32 for a long time and many times, which will cause the filter plate 32 to be quickly worn and then damaged. When the embodiment of the present invention is in use, when the filter plate 32 is blocked, the rainwater cannot be discharged, the water level of the rainwater will rise, and then After the water level is reached, the buoyancy will drive the buoyancy tube 52 and the buoyancy frame to move upwards through buoyancy, thereby driving the sliding seat 51 and the first rack 46 to mesh with the gear upwards, and stretching the telescopic rod, so that the rotation of the gear can drive the first rack 46 and the brush plate 49 to move. After the filter plate (32) is unblocked, the water level drops, and then under the action of the first rack 46 and the sliding seat 51's own gravity, it resets downwards, and then the first rack 46 is separated from the gear, thereby causing the brush plate 49 to lose its power source. Relying on the above arrangement, the brush plate 49 will only move when the water level in the water tank 13 is too high, thereby reducing the situation where the brush plate 49 is constantly moving back and forth, causing the filter plate 32 to be quickly worn, and at the same time, it can reduce the brush plate 49 from moving in windy weather. In the case of moving the friction filter plate 32, when the brush plate 49 is moving and cleaning, the cleaning frame 48 will drive the guide rod 62 and the pulley 63 to move, and then the semicircular block 61 will squeeze the pulley 63 to make it upward. When the pulley 63 is separated from the semicircular block 61, the second spring will push the brush plate 49 to reset upward. By providing a plurality of semicircular blocks 61, the brush plate 49 can move horizontally and the brush plate 49 can also move up and down, so as to apply a cleaning friction force of different angles, thereby improving the cleaning effect and reducing the cleaning dead angle. When the wind speed is high, the fan blades will be blown to rotate at a high speed. The fast rotation speed will cause the pull rope 45 and the connecting rod 47 to bear too much load, which will lead to deformation.When the embodiment of the present invention is in use, the rotation of the rotating shaft 43 will drive the multiple spring pieces and the arc-shaped friction block 72 to rotate, and then rely on centrifugal force to make the arc-shaped friction force move away from the rotating shaft 43. When the rotating shaft 43 rotates rapidly, the surface of the arc-shaped friction block 72 contacts the inner wall of the friction ring 71, and relies on friction to decelerate the rotating shaft 43, thereby reducing the rotation speed of the rotating shaft 43, thereby reducing the situation where the pull rope 45 and the connecting rod 47 are damaged due to the excessive rotation speed of the crank shaft 44. The roller 10 is provided to contact the pull rope 45, so as to convert the sliding friction between the pull rope 45 and the through hole into rolling friction, thereby reducing friction and further reducing the wear on the pull rope 45. When rainwater flows from the collection pipe into the water tank 13, it first enters the separation pipe 81 and then enters the water tank 13 from the top. The large particles of sediment in the rainwater will settle into the sand discharge pipe under the action of its own weight, and then enter the collection tube 82 for collection. After that, the large particles of sediment will enter the collection tube 82. Later, during routine maintenance, the staff can pull the top cover 84 and then take out the collection tube 82 through the connecting rope to remove the collected sediment. Relying on the above arrangement, it can collect a large amount of large particles of sediment contained in the rainwater for subsequent cleaning, thereby reducing the accumulation of a large amount of sediment in the water tank 13, which causes the capacity of the water tank 13 to decrease.
