Abstract
Description
Technical Field
[0001] This application relates to the field of municipal engineering, and in particular to a drainage structure for municipal roads. Background Art
[0002] The municipal drainage system is a very important livelihood project. After rainy days, it is often necessary to guide and discharge the accumulated water on the road surface through the drainage system.
[0003] Usually, drainage outlets are provided at the curb stones on both edges of the municipal road. The drainage outlets are directly connected to the underground drainage pipe network. The drainage outlets are located on the side of the curb stone facing the municipal road, and the flowing direction of the accumulated water on the road into the drainage outlets is horizontal.
[0004] Intercepting steel bars are usually fixedly installed at the drainage outlets of the curb stones. The intercepting steel bars can intercept large-volume objects in the water and prevent them from entering the drainage pipe network. However, for small-volume and heavy solid impurities, it is very difficult for the intercepting steel bars to play an intercepting role. After such impurities enter the drainage pipe network, it is difficult to clean them. Summary of the Invention
[0005] In order to improve the above problems, this application provides a drainage structure for municipal roads.
[0006] A drainage structure for municipal roads provided by this application adopts the following technical solutions:
[0007] A drainage structure for municipal roads includes a road surface. A curb stone is provided on the side of the road surface. A drainage hole is opened on the side of the curb stone facing the road surface. A sedimentation tank is opened on the road surface beside the drainage hole. A filter plate is provided at the mouth of the sedimentation tank on the road surface. The filter plate is used to close the mouth of the sedimentation tank, and a plurality of slag passing holes are opened on the filter plate.
[0008] Preferably, the filter plate is hinged to the wall of the sedimentation tank. The axial direction of the hinge shaft is horizontal. The hinge shaft of the filter plate and the sedimentation tank is located at the edge of the sedimentation tank far from the drainage hole; a control component is further included for controlling the rotation of the filter plate.
[0009] Preferably, the control component includes a limiting sill and an automatic torsion spring. The limiting sill is connected to the wall of the sedimentation tank on the side close to the drainage hole. The automatic torsion spring is connected to the hinge shaft of the filter plate. In the natural state, the end of the filter plate far from its hinge shaft abuts against the lower side of the limiting sill.
[0010] Preferably, the control component includes a top support rod. The top support rod is located in the sedimentation tank. After the filter plate rotates downward, it abuts against the top of the top support rod. After the filter plate abuts against the top support rod, a 2-cm gap is formed between the filter plate and the limiting sill.
[0011] Preferably, the slag passing hole is a rectangular hole, the length direction of the slag passing hole is perpendicular to the hinge axis of the filter plate, and the end of the slag passing hole close to the limit sill penetrates to the side edge of the filter plate far from the hinge shaft.

Detailed Description of the Embodiment
[0021] The following is a further detailed description of the present application in combination with the attached Figure 1-2 drawings.
[0022] An embodiment of the present application discloses a municipal road drainage structure, as Figure 1 shown, including a road surface 1, and a curb 2 is arranged at the edge of the road surface 1. A drainage hole 21 is opened on the side of the curb 2 facing the road surface 1. Below the road surface 1 is a municipal drainage pipe network (not shown in the figure), and the drainage hole 21 is directly communicated with the drainage pipe network. A sedimentation tank 11 is opened on the road surface 1 and beside the drainage hole 21, and the accumulated water on the road surface 1 passes above the sedimentation tank 11 during the process of flowing into the drainage hole 21.
[0023] As Figure 1 and 2 shown, a filter plate 3 is arranged at the notch of the sedimentation tank 11 on the road surface 1. A number of slag passing holes 31 are opened on the filter plate 3. The filter plate 3 can close the notch of the sedimentation tank 11, and the slag passing holes 31 can enable solid impurities with a smaller volume to pass through the filter plate 3 and enter the sedimentation tank 11. The filter plate 3 is hinged to the tank wall of the sedimentation tank 11. The hinge axis of the filter plate 3 and the sedimentation tank 11 is located at the edge of the sedimentation tank 11 far from the drainage hole 21, and the axial direction of the hinge axis is the horizontal direction. The drainage structure further includes a control component 4 for controlling the rotation of the filter plate 3. The control component 4 includes a limit sill 41 and an automatic torsion spring. The limit sill 41 is located at the lower edge of the drainage hole 21 and is slidably connected to the curb 2. The sliding direction is the horizontal direction and is perpendicular to the axis of the hinge axis of the filter plate 3. An adjusting bolt 24 is threadedly connected to the curb 2. The axis of the adjusting bolt 24 is parallel to the sliding direction of the limit sill 41. The end of the adjusting bolt 24 is rotatably connected to the limit sill 41. By rotating the adjusting bolt 24, the axial position of itself can be changed, so as to change the lateral position of the limit sill 41. A manhole cover 23 is arranged on the road shoulder above the curb 2. The manhole cover 23 can open or close the space above the drainage hole 21, providing a space condition for the operator to rotate the adjusting bolt 24. The automatic torsion spring is connected to the hinge axis of the filter plate 3. In the natural state, the automatic torsion spring applies an upward turning torque to the filter plate 3, so that one end of the filter plate 3 far from its hinge axis abuts against the lower side of the limit sill 41. If the limit sill 41 moves away from the road surface 1 when the adjusting bolt 24 is rotated, the limit sill 41 can move to a position where it does not block the turning of the filter plate 3, and the filter plate 3 can turn upward to open the sedimentation tank 11.
[0024] As Figure 1 and 2As shown, the slag hole 31 is a rectangular hole, the length direction of the slag hole 31 is perpendicular to the hinge axis of the filter plate 3, and the end of the slag hole 31 close to the limit sill 41 passes through the edge of the side of the filter plate 3 away from the hinge axis. When the water flows through the filter plate 3, the solid impurities carried in the water exert downward pressure on the filter plate 3, thereby causing the filter plate 3 to flip downward, and a gap appears between the filter plate 3 and the limit sill 41. Impurities with a particle size larger than the width of the slag hole 31 have the opportunity to enter the sediment tank 11 through the gap between the two. A slag basket 421 is placed in the sediment tank 11. The slag basket 421 is woven from steel wire and is densely covered with a number of small holes. A top support rod 42 is fixedly connected inside the slag basket 421, and the top support rod 42 is a steel column. When the slag basket 421 abuts against the bottom of the slag trough 11, the top support rod 42 and the bottom of the slag trough 11 are also relatively fixed, and the length direction of the top support rod 42 is the vertical direction; when the filter plate 3 flips downward to a gap width of 2 cm between it and the limit threshold 41, the filter plate 3 and the top of the top support rod 42 abut, and at this time, the side of the filter plate 3 cannot continue to flip down.
[0025] like Figure 1 As shown, a leaking hole 22 is provided on the curb 2, and the leaking hole 22 is located below the drain hole 21, and the internal space of the sediment tank 11 and the drain hole 21 are connected through the leaking hole 22. A rubber sealing piece 422 is fixedly connected to the slag basket 421, and when the slag basket 421 is placed in the sediment tank 11, the sealing piece 422 closes the leaking hole 22, and water cannot flow through the leaking hole 22. If the slag basket 421 is taken out of the sediment tank 11, the leaking hole 22 is opened, and the water in the slag basket 421 and the sediment tank 11 can flow into the drain hole 21 through the leaking hole 22, and the slag basket 421 containing impurities is taken out of the sediment tank 11 for cleaning.
[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
