1. when the flow of rainwater is small, rainwater permeates into the first drainage channels at two sides through the gaps of the surface layer, so that the rainwater is stored and utilized; when the rainwater flow is too large, the rainwater flows into the first drainage channel through the surface layer and flows into the second drainage channel through the drainage pipeline, so that the two pipes work simultaneously, the drainage quantity is increased, and the drainage efficiency is improved.
2. The filter layer at the outlet of the drainage device in the permeable asphalt pavement drainage system can be cleaned and replaced at regular time, the maintenance is simple, special maintenance equipment is not needed, and the maintenance cost is reduced.
3. The inside pore structure that can utilize the road surface of rainwater on the bituminous paving that permeates water in time discharges to make the road surface not have the large tracts of land ponding phenomenon to appear, this pore structure also has the effect of noise reduction. Meanwhile, the permeable pavement has better anti-skid performance in rainy days, and the driving safety is ensured.
4. The vehicle-mounted road surface water-retaining device plays a role in cities and seasons with much rainfall, can reduce water accumulated on the road surface, and does not influence the driving of vehicles on the road surface.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
The permeable asphalt pavement drainage system provided by the invention has the functions of filtering, storing water and draining water, can be used as a side ditch, and is suitable for most urban roads.
The attached drawing is a detailed drawing of the permeable asphalt pavement drainage system. The water-permeable asphalt pavement drainage system comprises a first drainage channel (1), a second drainage channel (2), a drainage pipeline (3) and a water level controller (6). The drainage pipeline (3) is made of impervious materials such as metal materials, plastic materials and the like. The first drainage channel (1) and the second drainage channel (2) are arranged on two sides of the surface layer (A) in parallel and connected together through the drainage pipeline (3), and one drainage pipeline is arranged at the side of the first drainage channel (1) every 500 meters, and the first drainage channel, the second drainage channel and the third drainage channel are of an integrated structure. The filter layers (5) are respectively placed at the first drainage outlet (8) and the second drainage outlet (9) of the first drainage channel (1) and the second drainage channel (2), so that the water quality purification effect can be achieved, and the maintenance is convenient. The left side of the first drainage channel (1) is provided with a filter screen (4) with the diameter equal to that of the channel, so as to prevent the permeable asphalt concrete of the surface layer (A) from entering the drainage channel along with rainwater. The water outlet of the permeable asphalt pavement drainage system can be arranged in crops, reservoirs, rivers and other places, and the discharged water can be secondarily utilized through filtration, so that water resources are saved. When the water flow of the permeable asphalt pavement drainage system is small, the first drainage channel (1) can meet the drainage requirement, and meanwhile, the filter layer can filter and purify the water quality; when the water flow is large, the water level controller (6) senses that the water level of the first drainage channel (1) reaches the limited height, the drainage pipeline is automatically opened, and at the moment, redundant water can be drained through the second drainage channel (2) to avoid waterlogging.
When the water accumulation amount of the permeable asphalt pavement drainage system is small in normal rainy days and the water flow is small, water accumulated in the permeable asphalt concrete of the surface layer can meet the drainage requirement through the first drainage channel (1), at the moment, if the first drainage outlet (8) is closed, the drainage pipe can play a role in storing water, and if the first drainage outlet (8) is opened, rainwater can be filtered to obtain purified water so as to be conveniently recycled. Asphalt pavement drainage system permeates water when heavy rainfall, discharge are great in the stormy weather, and the water that surface course water permeability pitch accumulated can advance into first drainage channel (1), and when water level controller (6) sensed the ponding and reachd the injecing height, automatic opening drainage pipe made ponding get into second drainage channel (2), and two pipes drainage simultaneously, drainage efficiency is high, reduces the road surface ponding.
The attached drawing is a transverse drawing of the water permeable pavement of the invention, wherein A, B, C, D is a structural drawing of the water permeable pavement. Permeable pavement divide into the four layers altogether, and first layer is surface course (A), and surface course (A) adopts water permeability asphalt concrete, and the advantage on this road surface is that the inside pore structure in rainwater accessible road surface in time discharges, makes the road surface not produce ponding, and this intercommunication pore structure has also played the effect of certain noise reduction. Meanwhile, the water permeable pavement has good anti-skid performance in rainy days, and the driving safety is ensured. The second floor is basic unit (B), and the basic unit is cement mortar, and the lower level all scribbles waterproof material about basic unit (B), prevents that surface course (A) from permeating water and getting into basic unit (B) and bed course (C). The third layer is a cushion layer (C), the cushion layer (C) belongs to a pavement structure layer, the material is generally graded broken stone, the particle size is 4-7cm, and the third layer mainly plays a role in bearing, water proofing and water proofing. The last layer is a roadbed (D), which is the main part of the road surface and is generally an earth-rock discrete material.
The construction sequence of the permeable pavement drainage system is as follows: firstly reinforcing and compacting the roadbed (D), then sequentially laying a cushion layer (C) and a base layer (B), arranging a drain pipe, and finally laying a surface layer (A).
