Detailed Description
In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the invention easy to understand, the invention is further described with reference to the specific drawings.
As shown in figure 1, for the garden road disclosed by the application, the garden road comprises a drainage groove 2 and a base plate 3 which are embedded in a soil layer 1 from bottom to top, a water baffle 4 is rotatably connected on two sides of the base plate 3, and a locking piece 5 is arranged on the water baffle 4.
As shown in figures 2 and 3, the base plate 3 is arranged along the full length direction of the garden road, upward flanges 6 are arranged on two sides of the width of the base plate 3, and one end of the water baffle 4 is rotatably connected with the upper ends of the flanges 6. Further, the width of the splash guard 4 is identical to the width of the bed plate 3.
The locking member 5 includes a locking lever 7, and a dovetail-groove-shaped sliding groove 8 is formed in the upper surface of the splash guard 4, and the sliding groove 8 is formed along the width direction of the splash guard 4. The section is locking lever 7 sliding connection of forked tail stake in sliding tray 8, and turn-ups 6 up end has seted up downwards and has supplied locking lever 7 male inserting groove 9.
The rotation axis between the water guard 4 and the base plate 3 is identical to the full length direction of the garden road, so that the water guard 4 has both an opened state perpendicular to the base plate 3 and a closed state parallel to the base plate 3 by rotating.
In sunny weather, the water baffles 4 are in a closed state, the two water baffles 4 are arranged one above the other at the time, the horizontally arranged water baffles 4 can be used as a road surface for pedestrians to pass through, and the water baffles 4 above the water baffles are parallel and level with the upper surface of the soil layer 1. Of the two water baffles 4, one end of the lower water baffle, which is far away from the flanging 6, is fixed with a cylindrical supporting piece 10, and the supporting piece 10 is abutted against the base plate 3 to keep the water baffle 4 parallel to the base plate 3.
After rainwater weather, when gardens road was crossed by ponding, make breakwater 4 perpendicular to bed plate 3 through rotating breakwater 4, then through operation locking piece 5, with locking lever 7 slip insert to inserting groove 9 in, can make breakwater 4 keep the state of drooping in bed plate 3 to form the current temporary channel 11 of supply pedestrian between two breakwaters 4.
As shown in figures 1 and 2, an asphalt water-resistant layer 12 is stuck on the outer side of the joint of the water baffle 4 and the base plate 3, and the water-resistant layer 12 is connected with the base plate 3 and the water baffle 4. Therefore, when the splash plate 4 is perpendicular to the bed plate 3, standing water outside the temporary path 11 is hard to enter the temporary path 11 by the water blocking layer 12. Then, accumulated water in the temporary passage 11 is cleaned, so that pedestrians can normally pass through the temporary passage 11 without being influenced by the accumulated water outside the temporary passage 11.
In addition, influence that gardens road is received ponding when reducing the precipitation is less in order to reduce. One end of the water baffle 4 far away from the base plate 3 is provided with a water permeable hole 13, and the water permeable hole 13 is a rectangular hole and is distributed along the length direction of the water baffle 4. Gaps are reserved between the two water baffles 4 arranged one above the other and between the water baffles 4 and the base plate 3, and the upper surfaces of the two water baffles 4 are obliquely arranged towards one end provided with the water permeable hole 13.
So set up, at the less rainwater weather of precipitation, the rainwater that falls on garden road flows into the below of breakwater 4 through the hole 13 of permeating water to reduce the catchment on the garden road, make things convenient for the pedestrian current. In addition, because the upper surface of breakwater 4 sets up to the hole 13 one side slope of permeating water, so can flow to the hole 13 of permeating water after the rainwater falls on the upper surface of breakwater 4, and then the efficient is leading-in water to the below of breakwater 4 more, reduces ponding on the breakwater 4. Meanwhile, the upper surfaces of the two water baffles 4 are obliquely arranged, so that the gap between the two water baffles 4 can be increased, and rainwater can flow into the water treatment device conveniently.
In order to prevent excessive impurities from entering between the water baffles 4 and causing blockage, a filter screen 14 is arranged in the water permeable hole 13. And, because the breakwater 4 is rotatably connected to the upper end of the burring 6, the distance between the lower one of the breakwater 4 and the base plate 3 is increased, so that more rainwater flowing down from the water penetration hole 13 can be accommodated.
A plurality of water filtering holes 15 are distributed on the base plate 3 in an equidistant array mode along the width direction and the length direction, and the water filtering holes 15 are communicated with the drainage groove 2 positioned below the base plate 3. When the breakwater 4 is in the open state, if there is rainfall this moment, then the rainwater that falls on the bed plate 3 can flow into the drain tank 2 of below after filtering through drainage hole 15 to reduce the ponding on the bed plate 3, be convenient for the pedestrian tramples and pass on the bed plate 3.
Furthermore, the water deflector 4 is prevented from entering the drain channel 2 too much water in the closed state. A rubber plug 16 is fixed on one of the two water baffles 4 below, the plug 16 is cylindrical, one end of the plug 16 is connected with the water baffles 4, and the other end of the plug is round. The number of the plugs 16 is the same as the number of the drainage holes 15, and when the water guard 4 is in a closed state, the plugs 16 are positioned in the drainage holes 15.
So set up, under breakwater 4 was in the horizontality, drainage hole 15 was plugged up to stopper 16 to avoid under the state that breakwater 4 was not opened, during the rainwater got into to water drainage tank 2 during precipitation weather, thereby avoid water drainage tank 2's water level too high, and then avoid breakwater 4 to open the back rainwater and spill over the water drainage tank 2 that the water level is too high, finally reduce breakwater 4 and appear ponding in 3 tops of bed plate when being in under the open mode.
As shown in fig. 2 and 3, the upper surface of the locking lever 7 is provided with anti-slip threads (not shown), and when the water guard 4 is in a horizontal closed state, the anti-slip threads can prevent a pedestrian from slipping when walking on the water guard 4. In addition, the locking bar 7 can be pushed more easily by the anti-slip thread when the splash plate 4 is in the vertical open state. However, the smooth surface of the locking lever 7 on the end near the insertion groove 9 makes the smooth surface of the locking lever 7 contact the water-blocking layer 12 in the open state of the splash guard 4, thereby inhibiting the seeping of water from the position where the water-blocking layer 12 contacts the locking lever 7 into the temporary channel 11.
The implementation principle of the embodiment is as follows:
in a sunny state, the water baffle 4 is in a closed state, and the water baffle 4 can be used as a common road for pedestrians to pass through. And under the weather that the precipitation is less, still have certain water permeability for the rainwater can flow in the below of breakwater 4 through the hole 13 of permeating water, thereby makes the surface ponding of breakwater 4 still less, and the pedestrian of being convenient for more passes through.
Under there is ponding state on the garden road after the rain, through opening breakwater 4 and utilizing locking piece 5 locking, can be so that breakwater 4 is in the open mode, forms the temporary channel 11 that supplies the pedestrian to pass between two breakwaters 4. After breakwater 4 is opened, ponding that originally lies in breakwater 4 top can flow in to water drainage tank 2 through drainage hole 15, and the ponding that lies in outside temporary passage 11 receives blockking of breakwater 4 to be difficult to get into temporary passage 11 in to make the pedestrian of being convenient for in the temporary passage 11 current. In addition, under breakwater 4 open mode, even there is certain precipitation, the rainwater also can flow into to the drainage Cao in through drainage hole 15 to make interim passageway 11 be difficult to ponding, be convenient for the pedestrian current.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
