Description

Technical Field

[0001] The utility model relates to the technical field of drainage, in particular to a road drainage structure. Background Art

[0002] There are three types of drainage methods for municipal roads: open, concealed and mixed. The open type is composed of street gutters, side ditches, drainage ditches, etc., which are open ditches or open channels; the concealed type uses concealed pipes for drainage, including street gutters, rainwater outlets, connecting pipes, trunk and branch pipes, various inspection wells and outlets; the mixed type is a combination of open and concealed drainage methods.

[0003] The National Patent Network has published a municipal road drainage structure with authorization number CN214613408U. "The pavement structure of the municipal road includes a surface layer, a permeable roadbed, a filter layer and a roadbed from top to bottom. The filter layer is buried with multiple drainage pipes connecting the permeable roadbed and the drainage ditch." This method uses the permeable roadbed to infiltrate rainwater on the road surface and discharge it into the drainage ditch through the drainage pipe. The rainwater infiltration is comprehensive, but the number of drainage pipes is limited. When the infiltrated rainwater cannot be discharged in time, it will accumulate in the road surface, making the water content of the road surface higher, affecting the subsequent infiltration of rainwater.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Example 1

[0028] like Figure 1 to Figure 4 As shown, a road drainage structure includes: a lane 1 and a sidewalk 2. The dividing line between the lane 1 and the sidewalk 2 in the attached figure is for the convenience of understanding the division between the lane 1 and the sidewalk 2, and does not mean that the lane 1 and the sidewalk 2 are independent. In actual construction, the lane 1 and the sidewalk 2 are constructed as a whole. At the same time, the lane 1 is set with a slope that is high in the middle and low on both sides, and the sidewalk 2 is also set with a slope toward the lane 1. The sidewalk 2 is higher than the lane 1, and a curbstone 10 is pre-buried at the connection between the sidewalk 2 and the lane 1;

[0029] A plurality of carriageway sewers 4 are provided at equal intervals along the length direction of the carriageway 1 on both sides near the sidewalk 2. A sewer 3 is built in the carriageway 1 directly below the carriageway sewer 4, and the carriageway sewer 4 is connected with the sewer 3. A plurality of sidewalk sewers 5 are provided at equal intervals along the length direction of the sidewalk 2 near the carriageway 1. The sidewalk sewer 5 is connected with the sewer 3 through a built connecting well 6. The connecting well 6 is inclined with one end of the sidewalk sewer 5 being higher than the sewer 3 and the other end being lower. Roadway sewers 4 and sidewalk sewers 5 are both provided with road manhole covers 7 at their wellheads, and grille openings 11 are provided on the road manhole covers 7.

[0030] When it rains, rainwater at the position of the driving lane 1 will first gather to both sides, and then flow into the sewer 3 through the driving lane sewer well 4. Rainwater at the position of the sidewalk 2 will first gather to the position of the curb 10, and then flow into the connecting well 6 through the sidewalk sewer well 5, and finally flow into the sewer 3 for unified drainage. Rainwater at the position of the sidewalk 2 will first be discharged through all its own sewer wells. When the rainfall is heavy or the drainage is not timely, the rainwater will flow over the curb 10 to the driving lane 1, and then be discharged through the driving lane sewer well 4, forming a double drainage structure of the driving lane 1 and the sidewalk 2. Overall, the number of sewer wells is increased and the drainage speed of rainwater is improved.

[0031] In this embodiment, the curbstone 10 is higher than the sidewalk 2 by 5-10 cm.

[0032] The curbstone 10 is set higher than the sidewalk 2, so that the rainfall at the sidewalk 2 can be accumulated, so that it can be discharged from the sidewalk sewer 5 as much as possible, delaying the spread to the lane 1, and sharing the drainage pressure of the lane sewer 4, while also reducing the amount of water on the lane 1.

[0033] In this embodiment, a well frame 8 is provided in the carriageway sewer well 4 and the sidewalk sewer well 5. An embedded part 14 is welded and installed on the outer wall of the well frame 8. The embedded part 14 extends to the corresponding position of the carriageway 1 and the sidewalk 2 to be fixed. A support beam 15 is welded and installed at the bottom of the well frame 8. A mesh frame 9 is provided in the well frame 8 above the support beam 15. A handle 13 is welded and installed on the mesh frame 9. Leakage holes 12 are evenly arranged at the bottom of the mesh frame 9, and the diameter of the leakage holes 12 is 3 cm ± 1 cm.

[0034] During rain drainage, the grille opening 11 can first block some larger debris such as branches, discarded packaging bags, etc., and secondly, it can further block smaller debris such as leaves together with the leakage holes 12 on the mesh frame 9, thereby comprehensively achieving the debris filtering effect, reducing the probability of debris entering the sewer 3 and causing blockage, and ensuring the smooth flow of the sewer 3;

[0035] When the grille opening 11 or the water leakage hole 12 is blocked, the debris in the grille opening 11 can be directly cleared away, or the road surface manhole cover 7 can be removed first, the mesh frame 9 can be lifted out from the handle 13, the internal debris can be cleared out at once and then put back in, and the blocked debris can be cleaned quickly. When there is a heavy rainstorm or a short thunderstorm, the mesh frame 9 can be directly taken out and the road surface manhole cover 7 can be retained. This can increase the drainage speed. At the same time, the manhole opening is always protected by the manhole cover, and pedestrians and vehicles are not easy to fall into the well and get injured.

[0036] Example 2

[0037] like Figure 5 to Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a green belt 16 and a non-motorized vehicle lane 17 are added, and the road manhole cover 7, manhole frame 8 and net frame 9 at the sidewalk 2 are moved to the non-motorized vehicle lane 17;

[0038] The road includes a carriageway 1, a sidewalk 2, a green belt 16 and a non-motorized vehicle lane 17, wherein the carriageway 1, the green belt 16, the non-motorized vehicle lane 17 and the sidewalk 2 are arranged in sequence, a non-motorized vehicle lane sewer 18 is built in the non-motorized vehicle lane 17, a plurality of non-motorized vehicle sewer wells 21 are built on the non-motorized vehicle lane 17 opposite to the non-motorized vehicle lane sewer 18, and a road surface manhole cover 7, a well frame 8 and a mesh frame 9 are also arranged at the position of the non-motorized vehicle sewer well 21;

[0039] The sidewalk 2 is paved with sidewalk bricks 19, the length and width of the top surface of the sidewalk bricks 19 are larger than the length and width of the bottom surface, and the sidewalk bricks 19 are evenly spaced with side notches 20 on the four sides. The sidewalk sewer 5 is built on the sidewalk 2 near the non-motorized vehicle lane 18. The sidewalk sewer 5 is arranged in a long groove shape, and the bottom of the sidewalk sewer 5 is connected to the non-motorized vehicle lane sewer 18 through a connecting well 6.

[0040] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
