Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal engineering technology, specifically to an asphalt concrete pavement structure with rapid drainage function. Background Technology
[0002] Municipal engineering refers to the construction of municipal infrastructure. Various public infrastructure projects that support urban life fall under the category of municipal engineering, such as common urban roads, underground pipelines, tunnels, waterways, and waste disposal projects.
[0003] Existing municipal roads are often constructed using asphalt and concrete materials. However, current asphalt concrete pavements have the disadvantage of accumulating rainwater during rainy days, resulting in poor drainage, which affects pedestrian passage. Furthermore, they lack the function of rainwater storage and utilization. When carrying out municipal greening work, tap water still needs to be used, which is not conducive to saving water resources.
[0004] Therefore, this utility model proposes an asphalt concrete pavement structure with rapid drainage function. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide an asphalt concrete pavement structure with rapid drainage function that can quickly drain rainwater accumulated on the road surface and collect rainwater.
[0006] The purpose of this utility model is achieved as follows: a sand and gravel layer is laid on top of the soil base layer, a waterproof layer is laid on top of the sand and gravel layer, drainage channels are provided at the left and right ends of the top of the waterproof layer, a concrete layer is laid on top of the waterproof layer between the two drainage channels, and an asphalt layer is laid on top of the concrete layer.
[0007] Several steel cages are embedded inside the concrete layer. Extension rods are fixed to the top and bottom of the steel cages respectively. The extension rods at the top of the steel cages extend into the interior of the asphalt layer, and the extension rods at the bottom of the steel cages pass through the waterproof layer and extend into the interior of the sand and gravel layer.
[0008] The upper surface of the asphalt layer is symmetrically provided with two rows of water channels extending from the middle of the asphalt layer to the left and right edges respectively. Each row includes several water channels arranged at equal intervals. Each water channel gradually slopes downward from the inner end to the outer end. The outer ends of the water channels in the row on the left side of the asphalt layer are connected to the drainage channels on the left side of the asphalt layer, and the outer ends of the water channels in the row on the right side of the asphalt layer are connected to the drainage channels on the right side of the asphalt layer.
[0009] A boss is fixed to the upper side wall of the drainage trough, and a filter screen is placed on the boss. The filter screen is located below the connection between the asphalt layer's water channel and the drainage trough. A drainage ditch cover is provided on the top of the drainage trough.
[0010] A left water storage culvert is located on the left side of the drainage ditch on the left, and a right water storage culvert is located on the right side of the drainage ditch on the right. Both water storage culverts are located at the top of the soil base. Several left drainage blind pipes are connected between the left drainage ditch and the left water storage culvert, and several right drainage blind pipes are connected between the right drainage ditch and the right water storage culvert. That is, one end of each left drainage blind pipe is connected to the left drainage ditch and the other end is connected to the left water storage culvert, and one end of each right drainage blind pipe is connected to the right drainage ditch and the other end is connected to the right water storage culvert.
[0011] Both water storage tunnels can be topped with green belts. Each water storage tunnel is equipped with a pump body connected to the bottom of the pumping pipe. The top of the pumping pipes of both water storage tunnels extends into the green belt and is equipped with rotating nozzles. Connecting pipes are installed on the side walls where the two pumping pipes extend into the green belt. Valves are installed on the top of the pumping pipes and the connecting pipes.
[0012] This utility model has the following beneficial effects:
[0013] By symmetrically and inclinedly opening water channels on the upper surface of the asphalt layer, rainwater falls onto the surface of the asphalt layer and quickly flows into the drainage channel along the inclined water channels, thereby achieving the purpose of rapid drainage of the road surface and avoiding water accumulation on the road. In addition, during the process of rainwater flowing into the drainage channel, garbage is intercepted on the surface of the filter screen. After being filtered, the rainwater enters the interior of the drainage channel, preventing the drainage channel from becoming blocked and facilitating the periodic centralized treatment of garbage by municipal sanitation workers.
[0014] By setting up water storage culverts and drainage blind pipes, rainwater inside the drainage ditch can flow through the pipe wall of the drainage blind pipe into the water storage culvert, achieving the purpose of storing rainwater. By setting up pumping pipes and pumps, the water inside the water storage culvert can be pumped out, and the green belt and asphalt layer can be sprayed by rotating nozzles. The connecting pipes facilitate the refilling of water for municipal vehicles, achieving the purpose of collecting and utilizing rainwater and saving water resources.
[0015] By installing steel cages and extension rods, the tightness of the connection between the concrete layer, waterproof layer, aggregate layer and asphalt layer can be enhanced, and the structural strength of the concrete layer can be increased. Attached Figure Description

[0017] Figure 2 It's enlarged. Figure 1 Schematic diagram of the structure at point A;
[0018] Figure 3 This is a schematic diagram of the asphalt layer in this utility model. Detailed Implementation
[0019] The following is combined Figure 1-3 The present invention will be further described below;
[0020] A sand and gravel layer 2 is laid on top of the soil base layer 1, and a waterproof layer 3 (such as polyethylene polypropylene waterproof membrane) is laid on top of the sand and gravel layer. Drainage channels 6 are provided at the left and right ends of the top of the waterproof layer. A concrete layer 4 is laid on top of the waterproof layer between the two drainage channels, and an asphalt layer 5 is laid on top of the concrete layer.
[0021] The concrete layer contains several steel cages 7. The top and bottom of the steel cages are fixed with extension rods 8. The extension rod at the top of the steel cage extends into the interior of the asphalt layer, and the extension rod at the bottom of the steel cage passes through the waterproof layer and extends into the interior of the sand and gravel layer. By setting up steel cages and extension rods, the tightness of the connection between the concrete layer, waterproof layer, sand and gravel layer and asphalt layer can be enhanced, and the structural strength of the concrete layer can be enhanced.
[0022] The upper surface of the asphalt layer is symmetrically provided with two rows of water channels 9 extending from the middle part of the asphalt layer to the left and right edges respectively. Each row includes several water channels arranged at equal intervals (the width of the water channels is preferably 10 cm). Each water channel gradually slopes downward from the inner end (i.e. the end located in the middle of the asphalt layer) to the outer end (i.e. the end close to the drainage channel). The outer ends of the water channels in the left row are connected to the drainage channel on the left side of the asphalt layer, and the outer ends of the water channels in the right row are connected to the drainage channel on the right side of the asphalt layer.
[0023] By symmetrically and inclinedly opening drainage channels on the upper surface of the asphalt layer, rainwater can quickly flow into the drainage channel after falling on the surface of the asphalt layer, thereby achieving the purpose of rapid drainage of the road surface and avoiding water accumulation on the road surface.
[0024] A boss 10 is fixed to the upper side wall of the drainage ditch, and a filter screen 11 is placed on the boss. The filter screen is located below the connection between the asphalt layer's water channel and the drainage ditch. A drainage ditch cover 12 is provided on the top of the drainage ditch. During the process of rainwater flowing into the drainage ditch, garbage is intercepted on the surface of the filter screen. After being filtered, the rainwater enters the interior of the drainage ditch, preventing the drainage ditch from becoming blocked and facilitating the periodic centralized treatment of garbage by municipal sanitation workers.
[0025] A left-side water storage culvert 13 is located on the left side of the drainage trough on the left, and a right-side water storage culvert 15 is located on the right side of the drainage trough on the right. Both water storage culverts are located at the top of the soil base. Several left-side blind drainage pipes 14 connect the left-side drainage trough and the left-side water storage culvert, and several right-side blind drainage pipes 16 connect the right-side drainage trough and the right-side water storage culvert. That is, one end of each left-side blind drainage pipe connects to the left-side drainage trough, and the other end connects to the left-side water storage culvert; similarly, one end of each right-side blind drainage pipe connects to the right-side drainage trough, and the other end connects to the right-side water storage culvert. By setting up water storage culverts and blind drainage pipes, rainwater inside the drainage trough can flow through the pipe walls of the blind drainage pipes into the interior of the water storage culverts, achieving the purpose of rainwater storage.
[0026] Both underground water storage channels can be topped with green belts. Each channel is equipped with a pump body 17, which is connected to the bottom of a pumping pipe 18. The pump body can be controlled by an external municipal control system. The top of the pumping pipes in both underground water storage channels extends to the green belt and is equipped with rotating nozzles 19. Connecting pipes 20 are installed on the side walls of both pumping pipes extending to the green belt. Valves are installed on the top of the pumping pipes and the connecting pipes. Water is pumped out of the underground water storage channels by setting up pumping pipes and pump bodies. The rotating nozzles can spray and wet the green belt and asphalt layer. The connecting pipes facilitate the refilling of water by municipal vehicles, achieving the purpose of collecting and utilizing rainwater and saving water resources.
[0027] Working principle: When rainwater falls on the surface of the asphalt layer, it flows quickly into the drainage ditch along the inclined water channel, thus achieving rapid drainage of the road surface and preventing water accumulation. During the process of rainwater flowing into the drainage ditch, garbage is intercepted on the surface of the filter screen. The filtered rainwater enters the interior of the drainage ditch, preventing blockage and facilitating the periodic centralized disposal of garbage by municipal sanitation workers. The rainwater inside the drainage ditch can flow through the wall of the drainage blind pipe into the interior of the water storage culvert, achieving the purpose of rainwater storage. When it is necessary to utilize the rainwater in the water storage culvert, the pump body is activated by the external municipal control system to pump the water out of the water storage culvert. Through rotating nozzles, the green belt and asphalt layer can be sprayed. The connecting pipe facilitates the refilling of water for municipal vehicles, achieving the purpose of rainwater collection and utilization and saving water resources.
[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
