Utility Model Content

[0005] In order to improve the water storage effect of the waterproof board, the present application provides an asphalt road reinforcement structure.

[0006] The asphalt road reinforcement structure provided in this application adopts the following technical solution:

[0007] An asphalt road reinforcement structure comprises a roadbed and reinforcement seats installed on both sides of the roadbed, the roadbed being sequentially laid with a waterproof board, a filling mesh layer, a concrete filling layer and an asphalt layer, a drainage pipe being pre-buried in the road, the drainage pipe being respectively buried in the asphalt layer, the concrete filling layer and the filling mesh layer at different positions along the vertical direction, the waterproof board being provided with interconnected drainage grooves and water collecting grooves, the bottom wall of the water collecting groove being provided with interconnected connection grooves and water collecting cavities, the reinforcement seat being provided with drainage holes, and the waterproof board being matched with the drainage holes.

[0008] By adopting the above technical scheme, in order to improve the water storage effect of the waterproof board, when it rains, rainwater passes through the drainage pipe and falls into the drainage groove and the water collecting groove on the waterproof board, wherein a part of the rainwater is discharged from the asphalt road through the drainage hole, and the other part of the rainwater flows into the connecting groove and the water collecting cavity through the water collecting groove. The water collecting cavity is utilized to improve the water storage effect of the waterproof board. Furthermore, when the temperature is high, the water in the connecting groove and the water collecting cavity evaporates slowly, thereby continuously cooling the asphalt road. Furthermore, the evaporated water vapor can be utilized to reduce the possibility of cracking of the asphalt layer pavement.

[0009] Preferably, a reinforcement assembly is provided on the reinforcement seat, and the reinforcement assembly includes a mounting seat and two clamping rings. A through groove is provided on the concrete filling layer, and a through hole is provided on the reinforcement seat. The mounting seat passes through the through hole and the through groove in sequence, and the mounting seat is slidably connected to the inner wall of the through hole and the inner wall of the through groove; a movable cavity is provided on the side wall of the through groove, and the two clamping rings are fixedly connected to the mounting seat, and the two clamping rings are against the inner wall of the movable cavity;

[0010] The reinforcement assembly also includes a control component capable of causing the clamping ring to press against the inner wall of the moving cavity.

[0011] By adopting the above technical solution, when it is necessary to enhance the stability of the reinforcement seats installed on both sides of the roadbed, the mounting seats are moved so that the mounting seats pass through the through holes and through grooves in sequence, and then the control components are used to deform the clamping ring until the clamping ring is tightly pressed against the inner wall of the moving cavity. Under the action of the friction force between the clamping ring and the moving cavity, the possibility of separation of the reinforcement seat and the concrete filling layer is reduced, thereby enhancing the stability of the reinforcement seats installed on both sides of the roadbed.

[0012] Preferably, the two clamping rings are fixedly connected with damping pads, and the two clamping rings are tightly pressed against the inner wall of the moving cavity through the damping pads.

[0013] By adopting the above technical solution and utilizing the damping pad, the friction between the clamping ring and the inner wall of the moving cavity is improved.

[0014] Preferably, the control component includes an adjusting screw and a moving block, the adjusting screw is threadedly connected to the mounting seat, the moving block is rotatably connected to the adjusting screw, the tube diameter of the moving block gradually increases from one end close to the adjusting screw to one end away from the adjusting screw, and the moving block is simultaneously pressed against the relative inner sides of the two retaining rings.

[0015] By adopting the above technical solution, when it is necessary to make the retaining ring press against the inner wall of the moving cavity, the adjusting screw is rotated, and the adjusting screw is moved under the action of the thread, and the movement of the adjusting screw drives the moving block to move. After the moving block contacts the retaining ring, the tube diameter of the moving block gradually increases from the end close to the adjusting screw to the end far from the adjusting screw, thereby causing the retaining ring to deform. Further, the adjusting screw is continued to be rotated until the retaining ring presses against the inner wall of the moving cavity.

[0016] Preferably, a filtering protection mechanism is provided on the asphalt layer, and the filtering protection mechanism includes a fixed block and a filtering cover. A placement groove is provided on the asphalt layer, and the filtering cover is sleeved on the end of the drainage pipe through the placement groove; the fixed block is fixedly connected to the inner wall of the placement groove, and a connected insertion groove and a rotation groove are provided on the filtering cover, and the fixed block can pass through the insertion groove, and the fixed block is slidably connected to the inner wall of the rotation groove;

[0017] The filtering protection mechanism also includes a positioning assembly for fixing the filtering cover;

[0018] The filter protection mechanism also includes a pushing component for pushing the filter cover to move.

[0019] By adopting the above technical scheme, in order to prevent garbage and other impurities from entering the drainage tube, the filter cover is moved to insert the fixed block into the insertion groove. After the fixed block moves into the rotation groove, the filter cover is rotated, and then the positioning component is used to fix the filter cover, thereby reducing the possibility of garbage and other impurities entering the drainage tube; when the filter cover needs to be removed, the positioning component limits the filter cover, and then the filter cover is rotated. After the fixed block moves into the insertion groove, the pushing component is used to move the filter cover, thereby facilitating the removal of the filter cover.

[0021] One end of the compression spring is fixedly connected to the protrusion, and the other end of the compression spring is fixedly connected to the inner wall of the sliding cavity.

[0022] By adopting the above technical solution, when the filter cover needs to be fixed, the filter cover is rotated so that the fixed block rotates in the rotating groove. After the fixed block contacts the protrusion, since the top of the protrusion is in an arc shape, the side wall of the fixed block can push the protrusion to move, thereby causing the protrusion to move into the sliding hole. Then the filter cover is continued to be rotated. After the fixed block contacts the side wall of the rotating groove, the compression spring pushes the protrusion to move, thereby causing the protrusion to be inserted into the positioning groove, thereby reducing the possibility of movement of the filter cover.

[0023] Preferably, an anti-falling ring is fixedly connected to the protrusion, and the anti-falling ring is slidably connected to the inner wall of the sliding cavity.

[0027] By adopting the above technical solution, when the filter cover needs to be removed, the limit of the positioning assembly on the filter cover is released, and then the filter cover is rotated. After the fixed block enters the insertion groove, the support spring pushes the pushing ring to move, and the movement of the pushing ring drives the filter cover to move, thereby achieving the purpose of facilitating the removal of the filter cover.

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

[0029] 1. In order to improve the water storage effect of the waterproof board, when it rains, rainwater passes through the drainage pipe and falls into the drainage groove and water collection groove on the waterproof board, part of which is discharged from the asphalt road through the drainage hole, and the other part of the rainwater flows into the connecting groove and the water collection cavity through the water collection groove. The water collection cavity improves the water storage effect of the waterproof board. Furthermore, when the temperature is high, the water in the connecting groove and the water collection cavity evaporates slowly, so that the asphalt road can be continuously cooled. Furthermore, the evaporated water vapor can be used to reduce the possibility of cracking of the asphalt layer pavement;

[0030] 2. When it is necessary to enhance the stability of the reinforcement seats installed on both sides of the roadbed, move the mounting seats so that the mounting seats pass through the through holes and through grooves in sequence, and then rotate the adjusting screw. Under the action of the thread, the adjusting screw moves, and the movement of the adjusting screw drives the moving block to move. After the moving block contacts the clamping ring, the diameter of the moving block gradually increases from the end close to the adjusting screw to the end far from the adjusting screw, thereby causing the clamping ring to deform. Further, continue to rotate the adjusting screw until the clamping ring is tightly pressed against the inner wall of the moving cavity. Under the action of the friction between the clamping ring and the moving cavity, the possibility of separation of the reinforcement seat and the concrete filling layer is reduced, thereby enhancing the stability of the reinforcement seats installed on both sides of the roadbed;

[0031] 3. In order to prevent garbage and other impurities from entering the drainage tube, the filter cover is moved so that the fixed block is inserted into the insertion groove. After the fixed block moves into the rotating groove, the filter cover is rotated so that the fixed block rotates in the rotating groove. After the fixed block contacts the protrusion, since the top of the protrusion is in an arc shape, the side wall of the fixed block can push the protrusion to move, so that the protrusion moves into the sliding hole, and then the filter cover is continued to be rotated. After the fixed block conflicts with the side wall of the rotating groove, the compression spring pushes the protrusion to move so that the protrusion is inserted into the positioning groove, thereby reducing the possibility of the filter cover moving, and further reducing the possibility of garbage and other impurities entering the drainage tube; when the filter cover needs to be removed, the filter cover is rotated. Since the end of the protrusion is in an arc shape, the inner side wall of the positioning groove can push the protrusion to move. After the protrusion rotates into the sliding hole, the filter cover can be continued to be rotated. When the fixed block moves into the insertion groove, the support spring pushes the push ring to move, and the push ring moves to drive the filter cover to move, thereby facilitating the removal of the filter cover.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses an asphalt road reinforcement structure. Figure 1 and Figure 2 An asphalt road reinforcement structure includes a roadbed 17 and a reinforcement seat 1 installed on both sides of the roadbed 17, a waterproof board 2, a filling mesh layer 13, a concrete filling layer 12 and an asphalt layer 11 are laid on the roadbed 17 in sequence, and a drainage pipe 14 is also pre-buried in the road. The drainage pipe 14 is respectively buried in the asphalt layer 11, the concrete filling layer 12 and the filling mesh layer 13 at different positions along the vertical direction, and a filtering protection mechanism 4 for filtering rainwater is arranged on the asphalt layer 11 corresponding to each drainage pipe 14, and a plurality of reinforcement components 3 for enhancing the stability of the reinforcement seat 1 installed on both sides of the roadbed 17 are arranged on the reinforcement seat 1.

[0040] Reference Figure 2 and Figure 3 The filtering protection mechanism 4 includes a fixed block 41, a filter cover 42, a positioning assembly 43 and a pushing assembly 47. A placement groove 111 is provided on the asphalt layer 11. The filter cover 42 is sleeved on the end of the drainage pipe 14 through the placement groove 111. The fixed block 41 is fixedly connected to the inner wall side of the placement groove 111. The filter cover 42 is provided with a connected insertion groove 421 and a rotation groove 422. The fixed block 41 can pass through the insertion groove 421, and the fixed block 41 slides on the inner wall of the rotation groove 422.

[0041] The positioning assembly 43 includes a protrusion 44 and a compression spring 45. A sliding hole 423 and a sliding cavity 424 that are connected are provided on the side wall of the rotating groove 422. The protrusion 44 is arranged through the sliding hole 423. The end of the protrusion 44 is arc-shaped. A positioning groove 411 is provided on the fixed block 41. The protrusion 44 is plugged into the positioning groove 411. An anti-falling ring 46 is fixedly connected to the protrusion 44. The anti-falling ring 46 slides on the inner wall of the sliding cavity 424. The anti-falling ring 46 is used to reduce the possibility of the protrusion 44 falling off from the filter cover 42.

[0042] One end of the compression spring 45 is fixedly connected to the protrusion 44 , and the other end of the compression spring 45 is fixedly connected to the inner wall of the sliding cavity 424 .

[0043] The pushing assembly 47 includes a pushing ring 48 and multiple supporting springs 49. The pushing ring 48 slides against the inner wall of the placement groove 111. The pushing ring 48 is tightly pressed against the filter cover 42. One end of the supporting spring 49 is fixedly connected to the pushing ring 48, and the other end of the supporting spring 49 is fixedly connected to the bottom wall of the placement groove 111.

[0044] In order to prevent garbage and other impurities from entering the drainage pipe 14, the filter cover 42 is moved to insert the fixed block 41 into the insertion groove 421. After the fixed block 41 moves into the rotation groove 422, the filter cover 42 is rotated to make the fixed block 41 rotate in the rotation groove 422. After the fixed block 41 contacts the protrusion 44, since the top of the protrusion 44 is in an arc shape, the side wall of the fixed block 41 can push the protrusion 44 to move, so that the protrusion 44 moves into the sliding hole 423. Then, the filter cover 42 is continuously rotated. After the fixed block 41 contacts the side wall of the rotation groove 422, the compression spring 45 pushes the protrusion 44 to move so that The protrusion 44 is inserted into the positioning groove 411, thereby reducing the possibility of the filter cover 42 moving, and further reducing the possibility of garbage and other impurities entering the drainage tube 14; when the filter cover 42 needs to be removed, the filter cover 42 is rotated. Since the end of the protrusion 44 is an arc shape, the inner wall of the positioning groove 411 can push the protrusion 44 to move. After the protrusion 44 is rotated into the sliding hole 423, the filter cover 42 can continue to be rotated. When the fixed block 41 moves into the insertion groove 421, the support spring 49 pushes the push ring 48 to move, and the movement of the push ring 48 drives the filter cover 42 to move, thereby facilitating the removal of the filter cover 42.

[0045] Reference Figure 1 and Figure 4 The waterproof plate 2 is provided with a plurality of interconnected drainage grooves 21 and a plurality of water collecting grooves 22, the bottom walls of the plurality of water collecting grooves 22 are provided with interconnected connecting grooves 23 and two water collecting chambers 24, the reinforcement seat 1 is provided with a plurality of drainage holes 15, and the water collecting grooves 22 are connected to the drainage holes 15.

[0046] When it rains, rainwater flows into the waterproof board 2 through multiple drainage pipes 14. Part of the rainwater passes through the drainage groove 21 and is then discharged from the inside of the asphalt road through the drainage hole 15. The other part of the rainwater passes through the collecting groove 22 and enters the connecting groove 23 and the collecting cavity 24 for collection. When the temperature is relatively high, the water in the connecting groove 23 and the collecting cavity 24 evaporates slowly, so that the water vapor can be used to continuously cool the inside of the asphalt road. The evaporated water vapor can further be used to reduce the possibility of cracking of the asphalt layer pavement.

[0047] Reference Figure 5 The reinforcement assembly 3 includes a mounting seat 31, two clamping rings 32 and a control component 33. A through groove 121 is provided on the concrete filling layer 12, and a through hole 16 is provided on the reinforcement seat 1. The mounting seat 31 passes through the through hole 16 and the through groove 121 at one time, and the mounting seat 31 is slidably connected to the inner wall of the through hole 16 and the inner wall of the through groove 121. A moving cavity 122 is provided on the side wall of the through groove 121. The two clamping rings 32 are fixedly connected to the mounting seat 31, and the two clamping rings 32 are fixedly connected with damping pads 36. The damping pads 36 on the two clamping rings 32 are tightly pressed against the inner wall of the moving cavity 122.

[0048] The control component 33 includes an adjusting screw 34 and a moving block 35. The adjusting screw 34 is threadedly connected to the mounting seat 31. A bearing sleeve is fixedly connected to the moving block 35. The adjusting screw 34 is rotatably connected to the moving block 35 through the bearing sleeve. The diameter of the moving block 35 gradually increases from the end close to the adjusting screw 34 to the end far away from the adjusting screw 34, and the moving block 35 is tightly pressed against the two retaining rings 32.

[0049] When it is necessary to enhance the stability of the reinforcement seat 1 installed on both sides of the roadbed 17, the mounting seat 31 is moved so that the mounting seat 31 passes through the through hole 16 and the through groove 121 in sequence, and then the adjusting screw 34 is rotated. Under the action of the thread, the adjusting screw 34 moves, and the movement of the adjusting screw 34 drives the moving block 35 to move. After the moving block 35 contacts the clamping ring 32, the pipe diameter of the moving block 35 gradually increases from the end close to the adjusting screw 34 to the end away from the adjusting screw 34, thereby causing the clamping ring 32 to deform. Further, the adjusting screw 34 is continued to be rotated until the clamping ring 32 is tightly pressed against the inner wall of the moving cavity 122. Under the action of the friction force between the clamping ring 32 and the moving cavity 122, the possibility of separation of the reinforcement seat 1 and the concrete filling layer 12 is reduced, thereby enhancing the stability of the reinforcement seat 1 installed on both sides of the roadbed 17.

[0050] The implementation principle of the asphalt road reinforcement structure of the embodiment of the present application is as follows: when it is necessary to enhance the stability of the reinforcement seat 1 installed on both sides of the roadbed 17, the installation seat 31 is moved so that the installation seat 31 passes through the through hole 16 and the through groove 121 in sequence, and then the clamping ring 32 is deformed by using the control component 33 until the clamping ring 32 is tightly pressed against the inner wall of the moving cavity 122. Under the action of the friction force between the clamping ring 32 and the moving cavity 122, the possibility of separation of the reinforcement seat 1 and the concrete filling layer 12 is reduced, thereby enhancing the stability of the reinforcement seat 1 installed on both sides of the roadbed 17;

[0051] In order to prevent garbage and other impurities from entering the drainage pipe 14, the filter cover 42 is moved so that the fixing block 41 is inserted into the insertion groove 421. After the fixing block 41 moves into the rotation groove 422, the filter cover 42 is rotated, and then the positioning component 43 is used to fix the filter cover 42, thereby reducing the possibility of garbage and other impurities entering the drainage pipe 14; when the filter cover 42 needs to be removed, the positioning component 43 is released to limit the filter cover 42, and then the filter cover 42 is rotated. After the fixing block 41 moves into the insertion groove 421, the pushing component 47 is used to move the filter cover 42, thereby facilitating the removal of the filter cover 42.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
