The drainage system of the present invention will be described with reference to examples.
Taking an asphalt pavement of an urban main road as an example, the total thickness of the pavement layer 10 is 150mm, and the base layer 20 is made of cement stabilized macadam and has the thickness of 36 cm. 40cm of soil of the second type is used for the sub-base layer 30. Below the sub-base 30 is a road bed 40. The rainwater well 5 penetrates through the asphalt pavement layer 10, the base layer 20, the subbase layer 30 and the roadbed 40, the upper end of the rainwater well 5 is a well cover 50, and the lower part of the rainwater well is a rainwater pipe 6.
The road surface layer is divided into an asphalt surface layer, an asphalt middle surface layer and an asphalt lower surface layer, the base layer is divided into an upper base layer of 18cm and a lower base layer of 18cm, the subbase layer is 40cm, and a road bed (cross slope) is arranged below the subbase layer. The prefabricated pipeline 3 adopts a structure with a rectangular outer shape and an oval inner shape so as to increase the compressive strength, the height of the prefabricated pipeline 3 is 800mm, the width of the prefabricated pipeline is 500mm, the width of the communication groove 32 at the upper end of the prefabricated pipeline is 50mm, the width of the mounting groove is 70mm, and the prefabricated pipeline is preferably formed by extending 10mm from the upper end of the communication groove 32 to two sides. The prefabricated pipeline 3 is made of reinforced concrete, reinforcing bars are mechanically welded by thin steel bars to form a steel reinforcement cage, C40 thin stone concrete is used for pouring, and anti-permeability concrete (permeability-resistant grade p6) can be used for manufacturing the prefabricated pipeline 3. The bottom of the prefabricated pipeline 3 is made of C15 concrete as a cushion layer, 1:2 cement mortar is used for bottoming, then the prefabricated pipeline 3 is installed, each section of the prefabricated pipeline 3 is 3.6m long, the prefabricated pipelines 3 are connected through socket-type tongues and grooves, and a rubber sealing ring water stop belt is used.
The upper end face of the prefabricated pipeline 3 is partially lapped with the asphalt lower surface layer, an asphalt permeable layer and a waterproof layer are arranged at the lapping position, asphalt mortar is filled between the outer side of the prefabricated pipeline 3 below the kerb 1 and the roadbed 40, the subbase layer 30, the base layer 20 and the roadbed layer to block joints and prevent rainwater from seeping down to the roadbed 40 along the outer side of the prefabricated pipeline 3.
A curb 1 with a plurality of rectangular drainage holes 2 is prefabricated by C50 fine stone concrete, and the size of the curb 1 is 900X300X150 mm. The height of the drain holes on the side (front) of the kerb facing the road surface is 250mm, the width is 20mm, the depth is 80mm, the interval between the drain holes 2 is 40mm (clear distance), and the total number of the drain holes is 15, so that the weight of the kerb can be reduced by 12 kg. The kerbstone was built in the mounting groove 33 with 1:2 cement mortar so that the communication groove 32 coincides with the depth of 80mm of the drainage hole 2 of the kerbstone 1 by a width of about 50 mm. The edges of the kerbstone 1 are lapped in the mounting grooves 33 by 10mm respectively.
The drainage branch pipes 34 at the bottom of the prefabricated pipeline 3 are made of HDEP high-strength reinforced plastic pipes with the diameter of 300mm, 8 drainage branch pipes 34 are connected to each rainwater well, and water is sealed by rubber sealing rings at the connection parts of the prefabricated pipeline 3 concrete walls and the rainwater well concrete walls so as to prevent rainwater from leaking and scouring roadbed and road surface structure layers. The rainwater pipe 6 adopts a reinforced concrete socket pipe with the diameter of 2.5m, the pipe seat adopts a C15 concrete pipe ear foundation, and the well cover 50 adopts a high-strength cast iron well cover.
The kerbstone 1 is 150mm in the pavement layer 10, which can make the water in the pavement structure smoothly discharged out through the drainage holes 2 (usually the same cross section of the road, the middle of the road is higher than two sides, the interior of the pavement structureIs/are as followsSeeps water, flows to both sides under the action of gravity, reaches the drainage holes 2 of the kerbs, is discharged into the prefabricated pipelines 3 through the drainage holes 2 and the communication grooves 32, and can be discharged into alternate rainwater wells 5 on the roadside through the prefabricated pipelines 3, so that the water in the pavement structure is thoroughly discharged. And every curb has 15 outlet openings, and it has 10cm high to expose on the pitch surface course, has increased drainage area, can be very fast with the rainwater discharge on the road surface, avoided former solid curb because the uneven settlement on road surface or the roadside ponding phenomenon that the unevenness caused) and road area is permeated to the basic unit under water, if the basic unit has the crack, then can further infiltrate down to the roadbed, and then cause the road surface to destroy thoroughly.
And because the drainage is smooth and easy, can ensure the road surface and drive a vehicle, pedestrian's safety. Especially, when the rainwater quantity is large, the well cover is washed away, and because the road surface is accumulated with water, great potential safety hazard is brought to driving and pedestrians. Through the outlet on a large amount of curb, can be so that the rainwater is not at the road surface deposit, the road surface field of vision is clear, reduces driving, pedestrian's potential safety hazard.
Through the improvement to current curb, form neotype curb, form new road drainage system, overcome in the past a large amount of rainwater of road cause the road surface drainage not smooth, drainage ability is not enough to cause surface ponding, the road water phenomenon of flooding even. The problem that the road pavement is damaged due to the fact that bottom-concave water seeps below a pavement structure layer due to uneven settlement of a roadbed or local unevenness of pavement construction is solved. Infiltration's rainwater is arranged to prefabricated pipeline 3 through the curb infiltration hole immediately, arranges the river course through downspout 6, has prolonged road life, has reduced the maintenance cost of road, has saved the preparation material of curb simultaneously.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
