[0002] With the rapid development of highway construction, the importance of roadbed and pavement drainage is gradually increasing. In the design and construction process, more and more projects begin to pay attention to the scientific planning and reasonable layout of the drainage system. At present, the drainage technology of highway roadbed and pavement presents diversified characteristics. Including the use of new materials (such as high-viscosity modified asphalt), the use of advanced drainage design schemes (such as drainage pavement), and personalized design combined with topography. In the process of highway operation, the maintenance and management of roadbed and pavement drainage has also been strengthened. Through regular inspection, cleaning and maintenance of drainage facilities, the normal operation of the drainage system is ensured, thereby extending the service life of the highway. In the system of highway roadbed drainage in my country, there is still a lack of relatively complete infrastructure. This leads to the easy formation of water accumulation on the road surface during rainy and snowy seasons, which poses a hidden danger to the safe passage of vehicles. There are unreasonable aspects in the design and construction of drainage systems in some highway projects. For example, the layout of drainage facilities is unscientific, the drainage capacity is insufficient, and the construction quality does not meet the standards. These problems will affect the normal operation of the drainage system. The drainage system gradually fails, which in turn affects the normal use of the highway, seriously damages the ecological environment, and the surrounding slope soil is prone to instability during precipitation, and the vegetation is also easily destroyed.

[0022] As Figure 1 shown, the present utility model provides an ecological drainage system, which includes a drainage ditch 2 arranged on the roadside of a road system 3. The drainage ditch 2 is arranged along the driving direction of the road system 3. A diversion slope groove 1 is arranged at the upper end of the drainage ditch 2. The upper surface of the diversion slope groove 1 is flush with the upper surface of the connection with the road system 3. The diversion slope groove 1 includes precast blocks 1-1 and a net vegetation skin 1-2 arranged on the precast blocks 1-1. The precast blocks 1-1 are laid on the drainage ditch 2 along the water flow direction of the drainage ditch 2, and the net vegetation skin 1-2 is laid on both sides of the precast blocks 1-1. In this application, the structure of the precast blocks 1-1 and the net vegetation skin 1-2 is arranged on one side of the road system 3. The precast blocks 1-1 effectively protect the net vegetation skin 1-2. Rainwater is preliminarily filtered after passing through the net vegetation skin 1-2. And precast blocks 1-1 are arranged downstream of the net vegetation skin 1-2, which can effectively prevent rainwater from scouring the net vegetation skin 1-2. Then, the drainage ditch 2 is used to discharge rainwater, which can effectively prevent rainwater from scouring the roadside of the road system 3 and prevent sundries from entering the drainage ditch. This application can effectively increase the anti-scouring ability of the grassy drainage ditch and at the same time increase the drainage ability of the grassy drainage ditch.

[0023] As Figure 1 shown, in the embodiment of this application, the diversion slope groove 1 is arranged in an arc shape at the upper end of the drainage ditch 2. The middle low position of the precast block 1-1 is located in the middle of the drainage ditch 2 and is arranged in an arc structure, which is beneficial to drainage.

[0024] In a specific embodiment of the present application, a lower vertical water collecting pipe 2-1 and a longitudinal water collecting pipe 2-2 are arranged in the drainage ditch 2. The lower vertical water collecting pipe 2-1 is vertically arranged in the drainage ditch 2. The upper end of the lower vertical water collecting pipe 2-1 is connected to the drainage outlet of the diversion slope trough 1, and the lower end of the lower vertical water collecting pipe 2-1 is connected to the longitudinal water collecting pipe 2-2. The longitudinal water collecting pipe 2-2 is arranged along the length direction of the drainage ditch 2 (i.e., the driving direction of the road system).

[0025] The drainage outlet of the longitudinal water collecting pipe 2-2 is connected to a catch basin 2-3, and a transverse drain pipe 2-4 is connected to the catch basin 2-3. Rainwater is guided into the catch basin 2-3 through the longitudinal water collecting pipe 2-2, and then the rainwater is discharged by using the transverse drain pipe 2-4. The catch basin 2-3 is used to precipitate the sediment, stones, etc. that fall in, preventing them from entering the transverse drain pipe 2-4 and causing blockage of the drainage channel.

[0026] Specifically, in a specific embodiment of the present application, the precast block 1-1 is arranged directly above the drainage ditch 2, and the net vegetation skin 1-2 is laid on both sides of the precast block 1-1. The net vegetation skin 1-2 in the present application specifically adopts a three-dimensional net turf. The three-dimensional net turf is planted on both sides of the precast block 1-1, and the precast block 1-1 can prevent the turf from being scoured at the bottom of the ditch.

[0027] The lower vertical water collecting pipe 2-1 is used to connect the drainage outlet of the diversion slope trough 1 and the longitudinal water collecting pipe 2-2, guiding the water on the road surface diverted by the diversion slope trough 1 into the longitudinal water collecting pipe 2-2 in the drainage ditch. The longitudinal water collecting pipe 2-2 is used to connect the lower vertical water collecting pipe 2-1 and the catch basin 2-3, guiding the water into the catch basin 2-3; the catch basin 2-3 is connected to the transverse drain pipe 2-4, and is used to introduce the water in the catch basin 2-3 into the transverse drain pipe 2-4 for discharge.

[0028] In a specific embodiment of the present application, the contact part between the road system 3 and the diversion slope trough 1 is a soil shoulder 3-1, which is beneficial to the construction of the diversion slope trough 1, prevents the road system 3 from baking the net vegetation skin 1-2 on the roadside after being exposed to high temperature in the sun, and is also beneficial to moisturizing the bottom of the net vegetation skin 1-2.

[0029] A catch basin 2-3 is arranged at the bottom of the drainage ditch 2, and the catch basin 2-3 is used for depositing silt and moisturizing by leakage.

[0030] A plurality of lower vertical water collecting pipes 2-1 are arranged along the length direction of the road system 3. The plurality of lower vertical water collecting pipes 2-1 are arranged at equal intervals, which is beneficial to construction and has strong material versatility.

[0031] In this application, a drainage ditch 2 is constructed on the soil section of the road system 3. A side ditch is excavated in the original soil, and then the cultivated soil is backfilled. Three-dimensional net turf or grass is laid. Concrete precast blocks are laid at the bottom of the three-dimensional net turf ditch for anti-erosion treatment. The space between the precast blocks is filled with cement mortar, and soil is piled on both sides of the precast blocks for grass planting and greening.

[0032] The water in the grass turf ditch flows into the longitudinal water collector through the lower vertical water collector, and then into the catch well through the longitudinal water collector. The water in the catch well is discharged through the transverse drain pipe to increase the drainage capacity of the grass turf ditch.
