DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the utility model.

[0015] Please refer to Figures 1-4 The utility model provides a roadbed reinforcing structure for highway design, including edge protection 1 and roadbed 2, the both sides of roadbed 2 are poured with edge protection 1, the inner wall of edge protection 1 is embedded with compaction structure 3, compaction structure 3 is in line with the inner wall of roadbed 2, the inner wall of roadbed 2 is inserted with drainage structure 4, and drainage structure 4 penetrates edge protection 1 and extends to the outside.

[0016] The filling stability of the roadbed 2 is ensured by the edge protection 1, and the vibration compaction structure 3 is used to compact the filled sand, stone, soil, lime, lime-soil and other materials, and the compacted soil forms a composite foundation. The compaction of the roadbed 2 increases the bearing capacity of the roadbed 2. The vibration compaction structure 3 can be used again during the regular maintenance and repair of the road surface, and the utilization rate is high. The drainage structure 4 is used to use the drainage consolidation method. The basic principle of the drainage consolidation method is that the soft soil foundation gradually drains the pore water under the action of the additional load, reduces the pore ratio, and produces consolidation deformation. In this process, the strength of the foundation soil gradually increases. It is composed of a drainage system and a pressurization system. The pressurization system is the compaction structure, which ensures the reinforcement effect of the roadbed 2, and the quality of the roadbed 2 is practical.

[0017] The vibration compaction structure 3 includes a vibration plate 31 inserted into the inner wall of the edge protection 1. The vibration compaction structure 3 is connected to the edge protection 1 through two springs 34. The outer wall of the two springs 34 is sleeved with a sheath 33. One end of the sheath 33 is connected to the vibration plate 31, and the other end of the sheath 33 is fixedly connected to the inner wall of the edge protection 1. The sheath 33 is made of soft rubber. Two vibration motors 32 are fixedly assembled on one side of the side wall of the vibration plate 31 close to the edge protection 1.

[0018] When the vibration compaction structure 3 is needed, first, start the two vibration motors 32 to drive the vibration plate 31 to vibrate and displace, and drive the gravel in the roadbed 2 to be stacked and compacted. At the same time, the two springs 34 play a supporting and shock-absorbing effect to prevent the edge protection from being damaged for a long time with the vibration plate 31. At the same time, the sheath 33 can protect the spring 34 to ensure its service life.

[0019] The drainage structure 4 includes a through pipe 45 penetrating the edge protection 1. The inner end of the through pipe 45 is connected to a funnel 46 and a water tank 41 through a three-way joint 44. The upper end of the funnel 46 is fixedly connected to a mesh tube 47. The inner wall of the water tank 41 is fixedly assembled with an inclined block 43. The higher side of the inclined block 43 is away from the through pipe 45. The inner wall of the water tank 41 is fixedly assembled with a separation net 42.

[0020] When the roadbed 2 is used, it will seep into the roadbed 2 in rainy weather. The water in the roadbed 2 will gradually collapse for a long time. At this time, the drainage structure 4 is needed. The water will enter the funnel 46 and the water tank 41 through the mesh tube 47 and the separation net 42 respectively. The water in the water tank 41 is guided into the three-way joint 44 through the inclined block 43, and then into the through pipe 45 through the three-way joint 44 and discharged.

[0021] The outer end of the through pipe 45 is fixedly assembled with a water pump 5.

[0022] The water pump 5 is more conducive to the drainage work.
