Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The inventor considers that the water on the road surface can be caused by the following aspects according to the road surface damage and water bleeding condition through practical observation and analysis:
1. The accumulated water in the side ditch of the road is permeated into the roadbed, the cement stabilized weathered sand subbase layer, the cement stabilized macadam base layer and the asphalt surface layer;
2. The water in mountain bodies at two sides of the road permeates into the roadbed, the cement stabilized weathered sand subbase, the cement stabilized macadam base and the asphalt surface layer through rock cracks;
3. Because of the water permeability phenomenon below the road surface, the groundwater is siphoned to the road surface under the state of vehicle traffic by heavy load traffic, and the water seepage phenomenon occurs.
Based on the field observation and analysis of the inventors, the following examples of the simulated water bleeding repair structure for asphalt road pavement are now proposed.
As shown in fig. 1, 2 and 3, the present embodiment provides an asphalt pavement simulated water-bleeding repair structure, which comprises a surface layer groove 10, a water seepage blind ditch 20, a gravel layer 30, a linoleum layer 40 and a concrete layer 50.
The surface layer groove 10 is arranged on the original road and extends to the roadbed layer 100 in depth, and the surface layer groove 10 extends from the road water-pumping position M to the side ditch 300 of the road. The water seepage blind ditch 20 is positioned in the surface layer groove 10 and is arranged in the road base layer 100, and extends to the side ditch 300 of the road along the extending direction of the surface layer groove 10, and the width of the water seepage blind ditch 20 is smaller than that of the surface layer groove 10. The stone layer 30 is disposed in the water permeable blind ditch 20. The felt layer 40 is laid and entirely covers the surface of the crushed stone layer 30. A concrete layer 50 is disposed in the skin tank 10 and pressed against the felt layer 40, and the surface of the concrete layer 50 is flush with the surface of the road asphalt layer.
After the original road is repaired by the asphalt road surface simulated water-bleeding repairing structure, water generated at the water-bleeding position firstly enters the water-bleeding blind ditch 20 and is guided to the side ditch 300 of the road through the gap of the broken stone layer 30 in the water-bleeding blind ditch 20, so that the water seeped in the roadbed layer 100 can be discharged in time, the road structure is prevented from being damaged chronically due to the seepage to the road surface, the service life of the road is prolonged, and the traffic safety of vehicles and pedestrians is ensured.
In addition, the felt layer 40 is disposed between the concrete layer 50 and the crushed stone layer 30, so that it is possible to effectively prevent the concrete mortar from entering the crushed stone layer 30 to fill the gap to affect the drainage function of the permeable layer of the crushed stone layer 30.
In this embodiment, as shown in fig. 1 and 2, the water seepage blind drain 20 is located at the middle position of the surface layer groove 10 in the width direction.
In this embodiment, as shown in fig. 1 and 2, the edge of the water seepage blind drain 20 is greater than or equal to 15cm, for example, 20cm, from the edge of the surface layer groove 10 in the width direction.
In this embodiment, as shown in fig. 1, the crushed stone layer 30 fills the weeping blind drain 20 and is flush with the surface of the weeping blind drain 20.
In this embodiment, as shown in fig. 1, the width of the felt layer 40 satisfies: the side portions of the linoleum layer 40 are laid and cover the side walls of the skin tank 10 so that the side edges of the linoleum layer 40 are located between the concrete layer 50 and the road original structure layer 200. The side edge portion of the felt layer 40 is disposed between the post-poured concrete layer 50 and the road original structure layer 200, forming an expansion joint between the concrete and the asphalt, preventing occurrence of irregular cracks, thereby protecting the road structure. If the crack appears at the position, the sealant is planned to be used for pouring the crack, so that the damage of the asphalt pavement such as edge biting and pit slot is prevented.
In this embodiment, the roadbed structure further comprises a reinforcement cage structure (not shown in the figure), the reinforcement cage structure is arranged in the water seepage blind ditch 20, and two ends of the reinforcement cage structure extend to two ends of the water seepage blind ditch 20, so that the roadbed strength is improved.
In this embodiment, as shown in fig. 4, the present invention further includes a barrier layer 60, where the barrier layer 60 is disposed between the surface layer groove 10 and the road original structure layer and the road shoulder on two sides of the water seepage blind ditch 20, and the barrier layer may be made of waterproof geotextile. If the rainfall in the flood season is concentrated, the drainage capacity of the side ditch 300 is insufficient, so that the water in the side ditch 300 permeates into the road base layer 100 and the road original structural layer 200 and forms a certain backflow to the water seepage blind ditch 20, and the blocking layer 60 of the embodiment can play a certain role in blocking the water accumulation, so that the backflow to the water seepage blind ditch 20 is reduced.
In this embodiment, as shown in fig. 4, the water permeable blind ditches 20 extend a predetermined length a from the road edge, and the gravel layer 30 and the concrete layer 50 also extend a predetermined length a from the road edge, and the predetermined length a is typically about thirty-four centimeters. By the design, influence of sand and stone on drainage effect due to long-term blockage can be reduced.
In this embodiment, as shown in fig. 4, three sides of one end of the crushed stone layer 30 extending out of the road edge are in contact with the outside, so as to improve the drainage effect of the crushed stone layer 30.
In this embodiment, as shown in fig. 3, the bottom surface of the crushed stone layer 30 is higher than the bottom surface of the side ditch of the road, so as to improve the drainage effect.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
