Description

Technical Field

[0001] The utility model relates to the technical field of roadbed and pavement, in particular to a roadbed and pavement that is easy to drain. Background Art

[0002] The roadbed is the foundation of a track or road surface, a geotechnical structure formed through excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation. It also bears the static and dynamic loads of the track and rolling stock, or the road surface and traffic loads, while also transmitting and dispersing the loads deep into the foundation. The pavement refers to a layered structure paved with various road construction materials on the roadbed that directly bears vehicle loads. A good quality pavement should have sufficient strength and good stability, and its surface should meet the requirements of being flat, dense, and anti-slip.

[0003] During the construction and use of roadbed and pavement, in order to prevent water accumulation on the road surface, a drainage structure is usually set up. Drainage pipes and drainage grooves are set at a certain position on the roadbed and pavement. The accumulated water on the road surface is discharged into the drainage groove through the drainage pipes. The accumulated water also needs to be filtered, and when blockage occurs, the filter device needs to be replaced immediately for unblocking. During the use of this type of roadbed and pavement, the drainage pipes are more troublesome to maintain. For this reason, we propose an easy-to-drain roadbed and pavement.

[0004] The Chinese patent (authorization announcement number: CN112663434A) proposes an easy-to-drain roadbed and pavement, including a roadbed, a pavement and two water retaining plates, the bottom of the pavement is fixedly connected to the top of the roadbed, and the bottoms of the two water retaining plates are respectively fixedly connected to the two sides of the top of the pavement, drainage grooves are provided on both sides of the roadbed, and trough bodies are provided on both sides of the pavement. The easy-to-drain roadbed and pavement can protect the drainage pipe by providing a protective plate. By rotating the fixed knob, the threaded column is driven to rotate. Under the action of the thread, the threaded column moves inside the threaded pipe toward the end away from the hollow block, so that the extrusion block is separated from one side of the connecting block, and then the slider is pulled to one side under the tension of the tension spring, driving the translation block and the insert block to move toward the inside of the hollow block, so that the insert block is separated from the inside of the slot, and then it is convenient to maintain or replace the damaged drainage pipe, and the drainage capacity is strong.

[0005] When the above scheme is used, only the damaged drainage pipes are repaired and replaced and the accumulated water is filtered through the filter. When the filter device is blocked, it cannot be replaced and unblocked immediately, and the filter replacement process is also troublesome. In order to solve the problem that the filter device cannot be replaced and unblocked immediately when it is blocked and the filter replacement process is also troublesome, we propose a drainage-friendly roadbed and pavement.

[0032] See also Figures 5 and 6 The flat plate 21 is clamped between the two sets of curved blocks 19. A gear 17 is welded and fixed to the end of the rotating disc 18 away from the circular box 20. A number of weight-reducing holes are opened inside the gear 17. The number of weight-reducing holes are distributed circumferentially inside the gear 17. The end of the gear 17 away from the rotating disc 18 is fixedly connected to the recovery wheel 15. A pull rope 16 is wound around the outer wall of the recovery wheel 15.

[0033] See also Figures 5 to 7Each set of limiting mechanisms 201 includes a rotating block 29, a plurality of weight-reducing holes are opened inside the rotating block 29, and the plurality of weight-reducing holes are distributed circumferentially on the outer wall of the rotating block 29. The rotating block 29 is internally threaded with a threaded tube 24, and the threaded tube 24 is located inside the mounting hole, and a pressing rod 23 is slidably connected inside the threaded tube 24. The bottom of the threaded tube 24 is fixedly connected to the abutting tube 28 through a stabilizing rod. The bottom of the abutting tube 28 is fixedly connected to the sleeve 27.

[0034] See also Figures 4 to 6 The bottom of the water storage box 3 is fixedly connected to a second elastic telescopic rod 14, and the output end of the second elastic telescopic rod 14 is fixedly connected to a latch 13, and the outer wall of the latch 13 is engaged with the gear 17.

[0035] Working principle: When it rains, the inclined wall 2 will guide the rainwater to the inside of the water storage box 3 on the left and right sides of the roadbed 1. When the rainwater flows into the inside of the rectangular groove 31, the activated carbon inside the two sets of filter boxes 9 will filter the rainwater. When the activated carbon inside the first layer of filter box 9 is blocked by dust, soil and garbage, the water inside the water storage box 3 will gradually increase, causing the weight of the water storage box 3 to gradually increase. The water storage box 3 will squeeze the first elastic telescopic rod 7 and also drive the second elastic telescopic rod 14 to move downward. The second elastic telescopic rod 14 drives the latch 13 The torsion spring 22 is released from the engagement with the gear 17. The torsion spring 22 releases the stored force and drives the two sets of curved blocks 19 to rotate through the flat plate 21. The curved blocks 19 drive the rotating disc 18 to rotate. The rotating disc 18 drives the gear 17 and the recovery wheel 15 to rotate simultaneously. The recovery wheel 15 releases the pull rope 16, making the pull rope 16 longer. At this time, the first return spring 12 drives the fixed rectangular plate 10 to move upward through the connecting rod 11, so that the first filter box 9 is lifted upward and can be filtered through the activated carbon inside the second set of filter boxes 9.

[0036] When all the activated carbon inside the filter box 9 has lost its filtering effect, it can be disengaged from the abutment with the outer wall of the filter box 9 by rotating the rotating block 29. At this time, the rod 23 is pressed downward, and the pressing rod 23 drives all the abutment arms 25 to abut against the inner wall of the abutment tube 28. All the abutment arms 25 shrink toward the inside of the abutment tube 28. At this time, the entire disassembly mechanism 101 is taken out from the inside of the mounting hole. When all the pressing rods 23 are taken out, the filter box 9 can be replaced, and the new filter box 9 can be placed in the corresponding position. At this time, it is only necessary to place the disassembly mechanism 101 between the two groups of corresponding mounting holes again, release the control of the pressing rod 23, and the second reset spring 26 drives the pressing rod 23 to reset. The abutment arm 25 abuts against the rectangular groove 31 or the outer wall of the fixed rectangular plate 10, and the limiting of the filter box 9 can be completed.
