Description

Technical Field

[0001] The utility model relates to the field of municipal engineering construction, in particular to a transverse side-divided zone drainage channel. Background Art

[0002] The side strips of urban municipal roads are an important part of road design. Their width is usually controlled between 1.5 meters and 3.0 meters. This design not only takes into account the overall beauty of the road, but also takes into account traffic smoothness and pedestrian safety. Figure 1 It is a top view of the existing side strip, such as Figure 1 As shown, an inner curb (3) is provided on the side of the side dividing strip (1) facing the motor vehicle road surface (2), and an outer curb (5) is provided on the side of the side dividing strip (1) facing the non-motor vehicle road surface (4), so as to clearly define the boundary between the motor vehicle lane and the non-motor vehicle lane and ensure the orderly flow of traffic.

[0003] For urban main roads, the side strips not only have a demarcation function, but also carry multiple functions, such as installing street lights to illuminate the road at night to ensure the safety of citizens' travel; planting street trees to beautify the urban environment and improve the level of urban greening. However, when street lights and street trees are installed in the side strips, and curbstones are installed on both sides, the internal space utilization becomes relatively limited, which is not conducive to the layout of sponge facilities. This is because the design and construction of sponge facilities need to consider the coordination and cooperation with existing facilities to avoid mutual influence. For example, sponge facilities such as rain gardens or permeable pavement need to keep a certain distance from street lights and street trees to ensure the normal functioning of their functions. This leads to serious waterlogging problems on the motorway in the rainy season, which brings inconvenience to citizens' travel and also increases the burden on the urban drainage system. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model discloses a transverse side-divided drainage channel, which avoids the occurrence of surface water on the motor vehicle road by introducing the runoff from the motor vehicle road surface into the non-motor vehicle road or auxiliary road.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A lateral side-divided drainage channel, characterized in that it comprises a shallow groove and a first groove and a second groove connected to two ends of the shallow groove;

[0007] The shallow groove is arranged laterally in the side dividing belt, and the shallow groove includes a groove bottom;

[0008] The first slot is formed on the inner curbstone, and the first slot includes a first slot bottom;

[0009] The second slot is formed on the outer curbstone, and the second slot includes a second slot bottom;

[0010] The motor vehicle road surface is not lower than the groove bottom one, the groove bottom one is not lower than the ditch bottom, the ditch bottom is not lower than the groove bottom two, and the groove bottom two is not lower than the non-motor vehicle road surface, thereby forming a continuous drainage channel.

[0011] Furthermore, the shallow groove also includes slope one and slope two respectively connected on both sides of the groove bottom, and the slope one and the slope two are inclined from both sides toward the groove bottom; the groove one also includes groove edge one and groove edge two respectively connected on both sides of the groove bottom one, and the groove edge one and the groove edge two are inclined from both sides toward the groove bottom one; the groove two also includes groove edge three and groove edge four respectively connected on both sides of the groove bottom two, and the groove edge three and the groove edge four are inclined from both sides toward the groove bottom two.

[0012] Furthermore, the slope of the side slope 1 is the same as that of the side slope 2, the slope of the groove edge 1 is the same as that of the groove edge 2, and the slope of the groove edge 3 is the same as that of the groove edge 4.

[0013] Furthermore, the slopes of the groove edge 1 and the groove edge 3 are the same, and the slope of the groove edge 1 is greater than the slope of the slope 1.

[0014] Furthermore, the slope of the first slope adopts a ratio of 1:3, that is, for every 3 units of horizontal advancement, 1 unit of vertical descent is achieved.

[0015] Furthermore, the motor vehicle road surface is higher than the groove bottom one, and the groove bottom one, the groove bottom, the groove bottom two and the non-motor vehicle road surface are at the same height.

[0016] Furthermore, it also includes a transition slope, which is connected between the motor vehicle road surface and the inner curb, and the transition slope is inclined from the motor vehicle road surface toward the inner curb, and the connection between the transition slope and the inner curb is not lower than the bottom of the groove.

[0017] Furthermore, the slope of the transition slope adopts a ratio of 1:6, that is, for every 6 units of horizontal advancement, 1 unit of vertical descent is achieved.

[0018] Furthermore, the widths of the groove bottom one and the groove bottom two are the same, and the width of the groove bottom one is smaller than the width of the groove bottom.

[0019] Furthermore, an impermeable membrane is provided at the bottom of the ditch.

[0020] The beneficial effects of the utility model are as follows:

[0021] (1) A continuous drainage channel is formed from the motor vehicle road surface to the non-motor vehicle road surface, and the height setting of each surface in the drainage channel can ensure that the runoff from the motor vehicle road surface flows unimpeded to the non-motor vehicle road surface, and then is discharged to the sponge facilities outside the road through the sidewalk cover culvert. There is no need to arrange sponge facilities in the side strip, which can meet the lighting and greening requirements on the side strip and avoid the occurrence of surface water on the motor vehicle road surface.

[0022] (2) The inclined setting of slope 1 and slope 2 can reduce the resistance of water flow, increase the water flow speed, and thus improve the drainage efficiency. The slopes of slope 1 and slope 2 are both in a ratio of 1:3. On the premise of achieving good drainage effect, they can ensure the stability and safety of the structure and prevent the slope from easily sliding or collapsing due to rain scouring or soil erosion.

[0023] (3) The height of the groove bottom 1 is the same as that of the ditch bottom, the width of the groove bottom 1 is smaller than the width of the ditch bottom, and the slope of the groove side 1 is greater than the slope of the side slope 1. The above design can guide the water flow on the motor vehicle road surface to enter the shallow ditch unimpeded without gathering in one groove.

[0024] (4) The height of the trough bottom 2 is the same as that of the ditch bottom, the width of the trough bottom 2 is smaller than that of the ditch bottom, and the slope of the trough side 3 is greater than that of the slope 1. The above design can slow down the outflow speed of water flow, prevent the water flow from forming eddies or scouring in the shallow ditch, and impact the soil, thereby aggravating soil erosion.

[0025] (5) The setting of the transition slope can guide rainwater to flow into the groove more evenly, avoid the phenomenon of water flow gathering between the motor vehicle road surface and the inner curb, and optimize the drainage effect. The slope of the transition slope adopts a ratio of 1:6, which is relatively gentle and can avoid dangerous situations such as bumps and even skidding during vehicle driving.

[0026] (6) An impermeable membrane is installed at the bottom of the ditch. On the one hand, it can prevent rainwater or other liquids from penetrating deep into the soil, destroying the structural stability of the soil, and causing soil erosion or loss. On the other hand, when rainwater flows into the shallow ditch, the impermeable membrane can prevent water from penetrating into the soil of the slope, thereby reducing the risk of slope instability caused by water.

[0037] Figure 2 FIG. 1 is a top view of the lateral side strip drainage channel in the embodiment. Figure 2 As shown, a lateral side strip drainage channel includes a transition slope 6, a groove 1 7, a shallow groove 8 and a groove 2 9. The direction from the motor vehicle road surface 2 to the non-motor vehicle road surface 4, that is, the rainwater discharge direction, will be described in detail below.

[0038] Figure 3 for Figure 2 Schematic diagram of the structure in direction II, such as Figure 3As shown, the transition slope 6 is connected between the motor vehicle road surface 2 and the inner curb 3, and the transition slope 6 is inclined from the motor vehicle road surface 2 to the inner curb 3. The accumulated water on the motor vehicle road surface 2 flows toward the inner curb 3 through the transition slope 6. The slope of the transition slope 6 adopts a ratio of 1:6, that is, for every 6 units of horizontal advancement, 1 unit of vertical descent. In this embodiment, the vertical descent height of the transition slope 6 is 0.05m, and the horizontal advancement distance of the transition slope 6 is 0.3m.

Figure 3 As shown, the connection between the transition slope 6 and the inner curb 3 (denoted as A) is not lower than the groove bottom 71, thereby ensuring that rainwater flowing from the transition slope 6 to the inner curb 3 can smoothly flow into the inner area of ​​the side strip 1 through the groove 7, and will not gather at the inner curb 3. In this embodiment, A is higher than the groove bottom 71, and the distance between A and the groove bottom 71 is 0.03m, and then the motor vehicle road surface 2 is higher than the groove bottom 71, and the distance between the motor vehicle road surface 2 and the groove bottom 71 is 0.08m.

The side slope 1 82 and the side slope 2 83 are inclined from both sides toward the trench bottom 81. The slopes 1 82 and 83 have the same slope and both adopt a ratio of 1:3, that is, for every 3 units of horizontal advancement, 1 unit of vertical descent is achieved. Figure 2-4As shown, the center lines of the ditch bottom 81 and the groove bottom 71 coincide, the ditch bottom 81 is not higher than the groove bottom 71, the width of the ditch bottom 81 is greater than the width of the groove bottom 71, and the slope of the side slope 82 is less than the slope of the groove side 72, thereby ensuring that rainwater can smoothly flow into the shallow ditch 8 through the groove 7 and will not gather at the groove 7. In this embodiment, the height of the ditch bottom 81 and the groove bottom 71 is the same, the width of the ditch bottom 81 is 0.4m, the width of the groove bottom 71 is 0.3m, the vertical drop height of the side slope 82 and the side slope 83 is 0.1m, and the horizontal advance distance of the side slope 82 and the side slope 83 is 0.3m. Figure 3 and Figure 5 As shown, in order to achieve the landscape effect, colored pebbles 84 with a particle size of 50mm-80mm are paved in the shallow ditch 8 and at the junction of the shallow ditch 8 and the side strip 1, and an anti-seepage membrane is provided at the bottom of the ditch 8.

[0041] like Figure 2 As shown, the second groove 9 is formed on the outer curb 5, the second groove 9 is connected to the shallow groove 8, and the second groove 9 includes a second groove bottom 91, a third groove side 92 and a fourth groove side 93 respectively connected to both sides of the second groove bottom 91. Figure 6 FIG. 2 is a rear view of the lateral side strip drainage channel in the embodiment, as shown in FIG. Figure 6 As shown, the groove side 3 92 and the groove side 4 93 are inclined from both sides toward the groove bottom 2 91, and the slopes of the groove side 3 92, the groove side 4 93, the groove side 1 72 and the groove side 2 73 are the same. Figure 6 In the figure, groove edge 1 72 and groove edge 2 73 are covered by groove edge 3 92 and groove edge 4 93 respectively, and the figure marks are omitted. In this embodiment, the vertical descent height of groove edge 3 92 and groove edge 4 93 is 0.23m, and the horizontal advance distance of groove edge 3 92 and groove edge 4 93 is 0.2m. Groove bottom 2 91 coincides with the center line of ditch bottom 81, and groove bottom 2 91 is not higher than ditch bottom 81 and not lower than non-motor vehicle road surface 4, ensuring that rainwater can flow from the shallow ditch 8 to groove 2 9, and then flow from groove 2 9 to non-motor vehicle road surface 4. In this embodiment, the heights of groove bottom 1 71, ditch bottom 81, groove bottom 2 91 and non-motor vehicle road surface 4 are all the same. Figure 6 In the figure, the groove bottom 1 71 is covered by the groove bottom 2 91, and the figure mark is omitted.

[0042] Specific operation process:

[0043] The motor vehicle road surface 2, the transition slope 6, the groove 1 7, the shallow groove 8, the groove 2 9 and the non-motor vehicle road surface 4 are connected in sequence to form a continuous drainage channel.

[0044] In the rainy season, rainwater on the motor vehicle road surface 2 first flows along the transition slope 6 to the inner curb 3, and then flows along the groove 7 on the inner curb 3 to the shallow ditch 8 in the side dividing strip 1. The bottom 81 of the shallow ditch 8 is provided with an impermeable membrane to prevent rainwater from seeping in. The rainwater entering the shallow ditch 8 flows along the groove 9 on the outer curb 5 to the non-motor vehicle road surface 4, and finally is discharged to the sponge facilities outside the road through the sidewalk cover culvert. There is no need to arrange sponge facilities in the side dividing strip 1, which can meet the lighting and greening requirements on the side dividing strip 1 and avoid the occurrence of water accumulation on the motor vehicle road surface 2.
