Description

Technical Field

[0001] The present application relates to the technical field of pavement structures, and in particular to an environmentally friendly permeable pavement and a method for using the same. Background Art

[0002] With the rapid development of my country's economy, more and more urban surfaces are covered by sealed hardened materials such as concrete and cement, which hinders the flow of moisture and heat on urban roads. Rainwater, as a non-traditional water source, was once used as a disaster prevention and control, but now it has become an important available water resource.

[0003] The current pavement structure generally adopts permeable structure to provide water permeability and air permeability. By collecting the accumulated water on the road surface, it can conserve groundwater, reduce the urban rain and flood load, and alleviate the water resource tension in different seasons and cities, playing a role in green environmental protection and water conservation.

[0004] However, after a certain period of use, the permeability of the permeable pavement will decrease due to pore blockage. It is necessary to use high-pressure water to flush the permeable pavement to improve the permeability of the pavement, but high-pressure water flushing will have a destructive effect on the pavement. Summary of the Invention

[0005] In order to alleviate the problem of damage to the road surface caused by high-pressure water scouring, the present application provides an environmentally friendly permeable road surface and a method of using the same.

[0006] In the first aspect, the present application provides an environmentally friendly permeable pavement adopting the following technical solutions:

[0007] An environmentally friendly permeable pavement comprises a base layer, a crushed stone layer and a concrete layer arranged in sequence from bottom to top; water guide cavities are arranged at intervals in the crushed stone layer along the length direction of the pavement, one end of each water guide cavity is connected to a water collection well, a permeable groove is opened on the concrete layer, a water pipe connected to the water guide cavity is provided at the bottom of the permeable groove, a primary filter plate is connected to the permeable groove, and a final filter plate is detachably connected to the top of the water guide pipe via a connector.

[0008] By adopting the above technical solution, when in use, rainwater on the road surface is filtered by the primary filter plate and flows into the permeable trough, and then filtered by the final filter plate. The final rainwater enters the water guide cavity through the water guide pipe and is discharged into the water collection well. When the final filter plate needs to be replaced, the connector is opened, disassembled, and replaced with a new final filter plate, thereby reducing the possibility of using high-pressure water to flush the permeable road surface and alleviating the problem of damage to the road surface caused by high-pressure water flushing.

[0009] Optionally, the connecting member includes a support spring and a guide block, a ring groove is provided on the top of the water pipe, a plug-in ring is integrally formed on the side wall of the final filter plate, the guide block is connected to the side wall of the plug-in ring, a first guide groove is provided on the side wall of the ring groove, the first guide groove is communicated with the ring groove, a second guide groove is provided on the bottom wall of the first guide groove, the second guide groove is annular and communicated with the ring groove, the plug-in ring is inserted into the ring groove and slides with the ring groove, the guide block is inserted into the first guide groove and slides with the first guide groove, when the final filter plate rotates, the guide block is inserted into the second guide groove and slides with the second guide groove, and when the guide block is located in the second guide groove, the support spring is supported between the plug-in ring and the ring groove.

[0010] By adopting the above technical solution, when connecting, the operator inserts the plug-in ring into the ring groove, and inserts the guide block into the first guide groove, applying downward pressure to the final filter plate. At this time, the support spring is compressed. When the guide block moves to the connection point between the first guide groove and the second guide groove, the final filter plate is rotated to rotate the guide block into the second guide groove. Under the action of the support spring to restore the elastic deformation force, the guide block is supported in the second guide groove to achieve a stable connection with the guide tube. When disassembly is required, the final filter plate is pressed downward to compress the support spring, and then the final filter plate is rotated to rotate the guide block to the connection point between the first guide groove and the second guide groove to release the force applied to the final filter plate. Under the action of the support spring to restore the elastic deformation force, the final filter plate moves upward, thereby realizing the disassembly and installation of the final filter plate.

[0011] Optionally, an opening and closing groove is provided on the side wall of the permeable groove, a reset spring is connected to the bottom of the opening and closing groove, one end of the reset spring is connected to the primary filter plate, the primary filter plate is inserted into the opening and closing groove and slides with the opening and closing groove, and an opening and closing part for controlling the opening and closing of the primary filter plate is provided on the concrete layer.

[0012] By adopting the above technical solution, since the primary filter plate is set on the road surface and needs to bear the gravity of the vehicles on the road surface, the structural strength of the primary filter plate is relatively large and will be made of iron or steel. The operator can control the opening and closing of the primary filter plate through the opening and closing parts, reducing the possibility of the operator manually opening and closing, saving manpower and improving work efficiency.

[0013] The cam is secured to the outside of the first lever and is secured to the inside of the cam, and the cam is secured to the outside of the first lever and is in communication with the cam.

[0014] By adopting the above technical solution, when in use, the operator steps on the pedal with his foot, and with the help of the operator's own gravity, the pedal moves downward, and the lifting spring is compressed. At the same time, the linkage block moves with the pedal and is inserted into the linkage groove. Then the operator turns the pedal, and the pedal drives the rotating ring to rotate, and the rotating ring drives the reset rope to rotate. The reset rope pulls the primary filter plate, so that the primary filter plate and the opening and closing groove slide together, and the opening and closing groove can be opened, which is convenient for the operator to replace the final filter plate. After the replacement is completed, lift the foot, and under the action of the reset spring, the primary filter plate covers the opening and closing groove, and at the same time drives the reset rope to reset.

[0015] Optionally, a plurality of rubber protrusions are provided on the top wall of the pedal.

[0018] By adopting the above technical solution, on the one hand, when the operator steps on the pedal, the pedal moves downward and presses the first rod downward, and the first rod drives the sealing plate to move downward. The sealing plate squeezes the air in the first tube, so that the air in the first tube is pressed into the annular air blowing pipe through the first tube, and then blown to the primary filter plate through multiple air nozzles on the annular air blowing pipe, which can blow away the debris accumulated on the primary filter plate, thereby reducing the possibility of the primary filter plate getting stuck during the sliding process.

[0019] Optionally, a sealing rubber ring is provided on the outer sleeve of the sealing plate, and the sealing rubber ring is in contact with the inner wall of the first cylinder.

[0020] By adopting the above technical solution and providing a sealing ring, the sealing performance between the sealing plate and the first cylinder can be improved.

[0021] In a second aspect, the present application provides a method for using an environmentally friendly permeable pavement.

[0022] A method for using an environmentally friendly permeable pavement comprises the following steps:

[0023] S1. Stepping on the pedal to move it downward, and then rotating the pedal to open the primary filter plate;

[0024] S2, inserting the plug-in ring into the ring groove, inserting the guide block into the first guide groove and rotating it into the second guide groove;

[0025] S3, releasing the force applied to the pedal;

[0026] S4. When replacement is required, step S1 is repeated, the final filter plate is rotated, the guide block is moved from the second guide groove to the first guide groove, and the final filter plate is taken out.

[0027] By adopting the above technical solution, the operator can use his own gravity to compress the lifting spring by stepping on the pedal. At the same time, the linkage block moves with the pedal and is inserted into the linkage groove. Then the operator turns the pedal, and the pedal drives the swivel to rotate, and the swivel drives the reset rope to rotate. The reset rope pulls the primary filter plate to open the opening and closing groove, and then the plug-in ring is inserted into the ring groove, which improves the convenience of installation. After the replacement is completed, lift your foot, and under the action of the reset spring, the primary filter plate covers the opening and closing groove, and at the same time drives the reset rope to reset, saving manpower.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. This application provides a water guide chamber, a water guide pipe, a primary filter plate, a connector, and a final filter plate. The connector can be opened, disassembled, and replaced with a new final filter plate, thereby reducing the possibility of high-pressure water scouring the permeable road surface and alleviating the problem of high-pressure water scouring causing damage to the road surface.

[0030] 2. The present application sets a support spring and a guide block, inserts the plug-in ring into the ring groove, and inserts the guide block into the first guide groove, exerting downward pressure on the final filter plate. At this time, the support spring is compressed. When the guide block moves to the connection point between the first guide groove and the second guide groove, the final filter plate is rotated to rotate the guide block into the second guide groove. Under the action of the support spring to restore the elastic deformation force, the guide block is supported in the second guide groove to achieve a stable connection with the guide tube. When disassembly is required, the final filter plate is pressed downward to compress the support spring, and then the final filter plate is rotated to rotate the guide block to the connection point between the first guide groove and the second guide groove to release the force applied to the final filter plate. Under the action of the support spring to restore the elastic deformation force, the final filter plate moves upward, thereby realizing the disassembly and installation of the final filter plate.
