Abstract
Description
Technical Field
[0001] This application relates to the field of road construction technology, and in particular to a road drainage structure. Background Technology
[0002] Currently, most road drainage systems consist of drainage channels installed on both sides of the road, which are connected to several drainage wells. A drainage grating is installed on the top of the drainage channel, and the height of the drainage grating is lower than the road surface. During rainy weather, water flows to the grating, is filtered of debris, and then discharged into the drainage channel.
[0003] Existing drainage structures have some problems. When encountering large drainage volumes, the drainage grates are easily clogged by fallen leaves and other debris carried by the water flow. When drainage is not smooth, water accumulation occurs. Once the water accumulates, the drainage grates are completely covered, making it impossible to accurately locate the drainage grates and clean them in a timely manner. Moreover, the accumulation of debris on the drainage grates makes it very inconvenient to clear the blockage, resulting in severe water accumulation on the road. Therefore, it is necessary to design a road drainage structure that is easy to clear blockages. Utility Model Content
[0004] This application provides a road surface drainage structure that facilitates clearing blockages.
[0005] The road surface drainage structure provided in this application adopts the following technical solution:
[0006] A road drainage structure includes a road body and drainage ditches on both sides of the road body. A curb stone is provided on the side of the drainage ditch. The height of the curb stone is higher than the height of the road body. A groove is provided on the side of the curb stone near the drainage ditch, and the lower end of the groove is connected to the drainage ditch. A first grid plate is movably connected to the outside of the groove. A second grid plate is provided on the drainage ditch. The first grid plate is connected to the second grid plate and can drive the second grid plate to move through the first grid plate.
[0007] Preferably, there are multiple grooves, and the multiple grooves are evenly arranged along the length direction of the curbstone. Both sides of the grooves are provided with sliding grooves and are slidably connected to the first grid plate through the sliding grooves. The lower end of the first grid plate is provided with an arc-shaped connecting part, which can be connected to the inner side of the second grid plate.
[0008] Preferably, the chute is inclined downwards, the first grating plate is an inclined plate, and the upper end of the first grating plate is provided with a bent portion, which can connect with the upper end of the groove and at this time the upper part of the bent portion is aligned with the surface of the curb stone.
[0009] Preferably, the upper end of the groove has recesses on both sides and the recesses are connected to the bent portion.
[0010] Preferably, both the first grating plate and the second grating plate are made of cast iron or resin, and the length of the first grating plate is greater than the length of the second grating plate.
[0011] Preferably, the main body of the road includes a base layer, a permeable layer and a surface layer arranged sequentially from bottom to top, with the height of the permeable layer and the surface layer on both sides being lower than the height of the middle.
[0012] Preferably, the base layer is a rammed soil layer, the permeable layer is a crushed stone cushion layer, and the surface layer is a permeable asphalt concrete layer.
[0013] Preferably, the width of the lower part of the drainage ditch is smaller than the width of the upper part, and seepage holes are provided on both sides of the drainage ditch, with the seepage holes respectively connected to the groove and the seepage layer.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. This application improves road drainage efficiency by setting grooves on the curb and installing a first grating plate on the outside of the grooves, and installing a second grating plate on the drainage ditch. This allows for filtration of drainage through the first and second grating plates. Furthermore, the first and second grating plates are connected, and the first grating plate can move the second grating plate, facilitating the clearing of blockages at the second grating plate and restoring drainage. Since the first grating plate is installed on the curb and is higher than the main road surface, even if the second grating plate is blocked and the location of accumulated water cannot be determined, the blockage can still be cleared through the first grating plate, facilitating drainage.
[0016] 2. By providing sliding grooves on both sides of the groove, it is convenient to connect the first grating plate. By providing an arc-shaped connecting part at the lower end of the first grating plate, it is convenient to connect the second grating plate. When the first grating plate is pulled, the arc-shaped connecting part can drive the second grating plate to move, thereby opening and clearing the blockage above the drainage ditch and improving drainage efficiency. By providing a bending part at the upper end of the first grating plate, it is convenient to fix and pull the first grating plate, making it easy to use. By providing a recess at the upper end of the curbstone that corresponds to the bending part, it can limit the position of the first grating plate.
[0017] 3. By setting up a permeable layer of crushed stone cushion and a surface layer of permeable asphalt concrete, the permeability of the road body can be improved, and the drainage efficiency can be increased. At the same time, permeable holes are set on both sides of the drainage ditch, which can allow the water that seeps down from the road body to flow into the drainage ditch and be discharged in time, ensuring drainage efficiency.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] This application discloses a road drainage structure.
[0025] Reference Figures 1 to 4 A road drainage structure includes a road body 1 and drainage ditches 2 disposed on both sides of the road body 1. A curbstone 3 is disposed on the side of the drainage ditch 2, the height of the curbstone 3 being higher than the height of the road body 1. A groove 301 is disposed on the side of the curbstone 3 near the drainage ditch 2, and the lower end of the groove 301 is connected to the drainage ditch 2. Specifically, in this embodiment, there are multiple grooves 301 on the curbstone 3, and these grooves 301 are evenly distributed along the length of the curbstone 3. A first grid plate 4 is movably connected to the outer side of the groove 301. A second grid plate 5 is disposed on the drainage ditch 2. The first grid plate 4 is connected to the second grid plate 5 and can move the second grid plate 5 through the first grid plate 4. Specifically, in this embodiment, a sliding groove 301a is disposed on both sides of the groove 301, and the groove 301a is slidably connected to the first grid plate 4. An arc-shaped connecting part 401 is disposed at the lower end of the first grid plate 4, and the arc-shaped connecting part 401 can connect to the inner side of the second grid plate 5.
[0026] Reference Figure 4 The chute 301a is inclined downwards, the first grating plate 4 is an inclined plate, and the upper end of the first grating plate 4 is provided with a bent part 402. The bent part 402 can connect with the upper end of the groove 301 and the upper part of the bent part 402 is aligned with the surface of the curb stone 3. The upper end of the groove 301 is provided with recesses 301b on both sides and the recesses 301b connect with the bent part 402.
[0027] Reference Figure 3The first grid plate 4 and the second grid plate 5 are both made of cast iron or resin. The length of the first grid plate 4 is greater than the length of the second grid plate 5, so that the first grid plate 4 can lift the second grid plate 5.
[0028] Reference Figure 2 The main body of the road 1 includes a base layer 101, a permeable layer 102, and a surface layer 103 arranged sequentially from bottom to top. The height of the two sides of the permeable layer 102 and the surface layer 103 is lower than the height of the middle. The base layer 101 is a rammed soil layer, the permeable layer 102 is a crushed stone cushion layer, and the surface layer 103 is a permeable asphalt concrete layer. The width of the lower part of the drainage ditch 2 is smaller than the width of the upper part. Both sides of the drainage ditch 2 are provided with permeable holes 201, which are connected to the groove 301 and the permeable layer 102 respectively. Some of the water accumulated on the main body of the road 1 can penetrate deep into the ground along the surface layer 103 and the permeable layer 102, and enter the drainage ditch 2 through the permeable holes 201, which is conducive to improving the drainage effect.
[0029] The implementation principle is as follows: This application sets a groove 301 on the curbstone 3 and sets a first grating plate 4 on the outside of the groove, and sets a second grating plate 5 on the drainage ditch 2. The drainage can be filtered through the first grating plate 4 and the second grating plate 5, thereby improving the road drainage efficiency. At the same time, the first grating plate 4 and the second grating plate 5 are connected, and the second grating plate 5 can be moved by the first grating plate 4, which is convenient for clearing blockages at the second grating plate 5 and restoring drainage. Since the first grating plate 4 is set on the curbstone 3 and is higher than the main road surface 1, even if the second grating plate 5 is blocked and the location of water accumulation cannot be determined, the blockage can be cleared through the first grating plate 4, which is convenient for drainage.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
