The construction and management of these highways need to follow specific technical standards and specifications to ensure their safe and efficient service to the economic development and resident travel in the urbanization area, and also undertake the transition between external highways and internal urban roads. On the basis of traditional highways focusing on transportation functions, more emphasis is placed on the service functions of surrounding urbanization areas, and slow traffic facilities such as auxiliary roads, non-motor vehicle lanes and sidewalks are added.
[0005] After adding facilities such as sidewalks, water is easy to accumulate on the side of the highway. In the traditional scheme, the pipeline drainage method is often used. According to the relevant design specifications of the highway, the rainwater pipeline needs to be arranged under the sidewalk, and a rainwater inlet is added at the edge of the road surface. A connecting pipe needs to be added between the rainwater inlet and the longitudinal rainwater pipe, which is a reinforced concrete structure. The size of the rainwater pipe matching the drainage capacity of the conventional 0.8*1.0cm size rectangular concrete side ditch is DN1000. The cost of DN1000 reinforced concrete pipe per meter is about 3000 yuan per meter. Increasing pipeline drainage in the longitudinal direction of the road not only has a large investment cost, but also is prone to blockage and difficult to clean. Therefore, it is urgent to develop a road surface drainage system suitable for urbanization area highway to effectively solve the problem of water accumulation on the side of the road after adding facilities such as sidewalks, and to improve the road surface drainage efficiency while reducing the investment cost, and to prevent blockage and easy cleaning.

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0031] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a road surface drainage system suitable for highways in urbanized areas, such as... Figure 1 As shown, the road surface 8 comprises a road surface, drainage curb stones 1, drainage U-shaped channels 3, rectangular side ditches 7, and sidewalk 9 paving facilities on both sides of the road surface 8, as well as ordinary curb stones. It should be noted that the drainage curb stones 1, drainage U-shaped channels 3, and rectangular side ditches 7 need to be installed at certain intervals along the edge of the road surface, based on the catchment area of the road and its surroundings, and can be densely installed at the low points of the longitudinal vertical curves of the road; ordinary curb stones are installed at other locations. In this embodiment, the road surface is a common Class I highway pavement structure found in engineering projects, comprising a 4cm + 8cm asphalt surface layer and a 3*18cm cement-stabilized crushed stone base layer.
[0032] like Figure 1 As shown, drainage curb stones 1 are installed on both sides of the driving surface of the highway 8 where drainage measures are required. A cement mortar pad and a concrete base are installed beneath the drainage curb stones 1 to ensure their installation stability. In this embodiment, both the ordinary curb stone and the drainage curb stone are rectangular in shape and are prefabricated from concrete. Standardized prefabrication and mass production improve construction progress.
[0033] like Figure 1 As shown, a drainage U-shaped channel 3 is connected to the side of the drainage curb 1 away from the road surface 8. The drainage U-shaped channel 3 consists of two side walls and a bottom wall. It should be noted that the conventional road surface 8 has a certain slope, and the bottom wall of the drainage U-shaped channel 3 also has the same slope as the road surface; that is, the bottom wall at one end connected to the drainage curb 1 is higher than the bottom wall at the other end, thus facilitating the drainage of water from the road surface 8. It is understandable that a drainage U-shaped channel 3 is not necessary on the side of a regular curb (not the drainage curb 1) away from the road surface 8.
[0034] like Figure 1As shown, the drainage U-shaped groove 3 is arranged below the pavement of the sidewalk 9, and the prefabricated steel plate 2 is arranged between the drainage U-shaped groove 3 and the pavement of the sidewalk 9, for supporting the sidewalk 9 and protecting the drainage U-shaped groove 3. The end of the drainage U-shaped groove 3 away from the highway pavement 8 is connected with the rectangular side ditch 7; specifically, a conventional porous cement gravel longitudinal blind ditch 4 is arranged between the drainage U-shaped groove 3 and the rectangular side ditch 7, and a longitudinal soft water-permeable pipe 5 is arranged at the bottom of the porous cement gravel longitudinal blind ditch 4, and the side of the longitudinal soft water-permeable pipe 5 away from the drainage U-shaped groove 3 is connected with a plurality of PVC drainage pipes 6 corresponding to the position of the drainage U-shaped groove 3, one end of the PVC drainage pipe 6 is connected with the longitudinal soft water-permeable pipe 5, and the other end penetrates through the side wall of the rectangular side ditch 7 and extends into the rectangular side ditch 7. It can be understood that the longitudinal soft water-permeable pipe 5 and the PVC drainage pipe 6 adopt the prior art, and the PVC drainage pipe 6 is arranged obliquely, that is, the end connected with the longitudinal soft water-permeable pipe 5 is higher than the end connected with the rectangular side ditch 7.
[0035] It should be noted that the rectangular side ditch 7, the porous cement gravel longitudinal blind ditch 4 and the longitudinal soft water-permeable pipe 5 are arranged along the highway; according to the overall drainage system and scheme of the road, drainage zones are divided, and the rectangular side ditch 7, the porous cement gravel longitudinal blind ditch 4 and the longitudinal soft water-permeable pipe 5 are disconnected at the rainwater discharge port position, for example, when the highway passes through a natural river.
[0036] The rectangular side ditch adopted in the embodiment is a rectangular concrete cover plate side ditch, and the cost per meter is about 1500 yuan, which is much lower than the cost of the corresponding specification rainwater pipe under the same drainage capacity; in some embodiments, the rectangular side ditch can also adopt a more economical mortar-laid flagstone cover plate side ditch, which has relatively lower cost.
[0037] As shown in Figure 1 The porous cement gravel longitudinal blind ditch 4 adopts the drainage method at the end of the roadbed and pavement in the conventional highway construction project, a cement cushion layer is arranged at the bottom thereof for preventing the downward infiltration of rainwater from having adverse effects on the pavement structure, and a concrete pouring cover is arranged at the top thereof for forming protection and preventing the porous cement gravel longitudinal blind ditch 4 from losing the drainage function.
[0038] As shown in Figure 2 A plurality of rectangular water release holes are arranged at intervals along the length direction of the drainage curb stone 1, and each rectangular water release hole is connected with a water falling step in the interior of the drainage curb stone, and the water falling step is arranged to increase the water passing capacity.
[0039] As shown in Figure 4As shown, the width between the two side walls of each drainage U-shaped groove 3 is consistent with the total width between the two end drop steps in each drainage curb 1, that is, the drainage U-shaped groove 3 is not longitudinally arranged along the road surface 8, but is arranged corresponding to the drop steps of the drainage curb 1. That is, the width size of the drainage U-shaped groove 3 matches the water passing capacity of the drainage hole of the drainage curb 1.
[0040] As shown in the drawings, Figure 3 As shown, a plurality of micro grit chambers 10 are arranged on the bottom wall of the drainage U-shaped groove 3 along the length direction of the drainage U-shaped groove, the length direction of the micro grit chamber 10 is perpendicular to the length direction of the drainage U-shaped groove 3, and the spacing between the micro grit chambers 10 is equal, which can filter out small sand and gravel mixed in the road surface rainwater, effectively alleviate the blockage problem of the drainage channel, ensure the long-term water passing capacity of the drainage channel, and only need to remove and restore the local sidewalk paving for later dredging, which has less impact on traffic. It can be understood that the drainage U-shaped groove 3 is also a concrete prefabricated structure.
[0041] It can be understood that the rainwater of the road surface 8 enters the drainage U-shaped groove 3 through the drainage curb 1, is first filtered by the plurality of micro grit chambers 10 to remove small sand and gravel mixed in the road surface rainwater, and then flows into the porous cement gravel longitudinal blind ditch 4, which is also filtered to remove some impurities, and finally flows into the rectangular side ditch 7 through the longitudinal soft permeable pipe 5 and the PVC drainage pipe 6.
[0042] As shown in the drawings, Figure 3 、 Figure 5 The top of the drainage U-shaped groove 3 is open, and the top of the two side walls of the drainage U-shaped groove is provided with a clamping groove for supporting the prefabricated steel plate 2; as shown in the drawings, Figure 1 、 Figure 5 The length of the prefabricated steel plate 2 is equal to the length of the drainage U-shaped groove 3, and the width is equal to the width between the clamping grooves at the top of the two side walls of the drainage U-shaped groove 3.
[0043] In this embodiment, the paving of the sidewalk 9 uses the prefabricated concrete paving bricks commonly used in engineering, and when inspection or dredging is needed, the concrete paving bricks are removed, and then the prefabricated steel plate is removed to expose the drainage U-shaped groove; the rectangular side ditch 7 also uses the cast-in-place concrete cover plate side ditch commonly used in engineering.
[0044] The utility model discloses a drainage curb with drop steps inside, which increases the water passing capacity, quickly drains the rainwater collected on the road surface to the drainage U-shaped groove connected to the other side of the drainage curb, reduces the accumulation time of the rainwater on the road surface, and improves the driving comfort.
[0045] The fine sand mixed in the rainwater is filtered and deposited through the micro grit chamber of the drainage U-shaped groove, and then is discharged into the rectangular side ditch 7 through the porous cement rubble longitudinal blind ditch 4, the longitudinal soft permeable pipe 5 and the PVC drainage pipe 6, so as to slow down the blockage of the drainage channel; and in the drainage system of the utility model, the drainage curb 1 and the drainage U-shaped groove 3 are not arranged along the road surface, but are arranged at the edge of the road surface at intervals according to the road and the surrounding catchment area, and can be arranged at a high density at the low point of the vertical curve of the road longitudinal section, so that the cost is relatively more economical.
[0046] In addition, if the drainage channel is blocked, the paving of the corresponding sidewalk of the drainage curb can be removed, the prefabricated steel plate above the corresponding drainage U-shaped groove is opened, and the cleaning and inspection can be carried out, so that the later dredging is convenient and has little influence on road traffic; in addition, the required components such as the drainage curb, the drainage U-shaped groove and the prefabricated steel plate are prefabricated and processed in advance, so that the construction period can be saved.
[0047] Although the specific embodiments of the utility model are described in combination with the drawings, the utility model is not limited to the above, and those skilled in the art should understand that various modifications or changes made on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
