Description

Technical Field

[0001] This utility model relates to the field of mountain flood interception ditch technology, and in particular to an intensive flood interception ditch. Background Technology

[0002] In recent years, frequent extreme weather events have led to recurring urban flooding problems in major cities, causing significant economic losses and posing a serious threat to the production, lives, and property safety of urban businesses and residents. While there are many causes of urban flooding, the primary reason lies in the inadequacy of urban flood control and drainage systems. Interception ditches, as an important component of urban flood control systems, suffer from the following problems:

[0003] 1) Urban land is scarce, municipal roads, highways, and residential areas are built close to mountains, and the construction land for flood interception ditches is limited, requiring the occupation of sensitive areas such as residential areas and woodlands, which makes implementation difficult;

[0004] 2) Flash floods usually carry a lot of dead branches, fallen leaves, mud and sand, which can easily cause blockages in the drainage system. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an intensive flood interception ditch that can significantly reduce the area of ​​land occupied and simplify planning.

[0006] An intensive flood interception ditch according to an embodiment of the present invention includes a water conveyance channel, a water collection ditch, a water collection well, and a sedimentation weir. The water conveyance channel is buried underground, and an inlet is provided at one end of the water conveyance channel. The water collection ditch is located on one side of the water conveyance channel, with one side being a mountain or slope and the other side being a green belt or road. The water collection well is located in the water collection ditch, and water flows from the water collection ditch into the water collection well. The middle part of the water collection well is connected to the water inlet, and the lower edge of the water inlet is higher than the lowest point of the water collection well. The lower end of the sedimentation weir is hinged to the lower edge of the water inlet. After the water flows into the water inlet, it rises along the sedimentation weir, crosses the sedimentation weir, and enters the water conveyance channel.

[0007] It has at least the following beneficial effects: the function of the water conveyance canal is to ultimately collect rainwater and transfer it to prevent urban flooding; the function of the collection ditch is to collect rainwater at the junction of the mountain, slope and other places with elevation differences and the road or green area, so as to collect rainwater at the lower level and prevent rainwater from accumulating in low-lying areas and causing flooding; the function of the collection well is to further collect the rainwater from the collection ditch and transfer it to the water conveyance canal; the sedimentation weir can block the lower end of the water inlet, so that rainwater cannot directly enter the water conveyance canal from the lower end of the water inlet. Instead, when the water level in the collection well rises above the upper edge of the inclined sedimentation weir, it will naturally flow into the water conveyance canal. In this way, the mud and sand in the water flow will not enter the water conveyance canal with the water flow, but will be settled at the bottom of the collection well under the action of gravity. By moving the water conveyance canal, which requires the most land area, underground, and constructing the water conveyance canal from the bottom up, the land area occupied by the flood channel can be significantly reduced, and the planning difficulty can be reduced. At the same time, the collection wells and collection ditches can be transported and installed after being manufactured in the factory. The civil engineering work of the water conveyance canal and the construction work of the collection wells and collection ditches can be carried out simultaneously, which greatly improves the construction efficiency.

[0008] According to some embodiments of the present invention, the cross-section of the water collection ditch is V-shaped, and the water collection well is located at the lowest point of the water collection ditch.

[0009] According to some embodiments of the present invention, a primary sedimentation tank is provided around the water collection well, the primary sedimentation tank is located in the water collection ditch, and the wellhead of the water collection well is higher than the upper edge of the primary sedimentation tank.

[0010] According to some embodiments of the present invention, a primary sedimentation tank is provided around the water collection well, the primary sedimentation tank is located in the water collection ditch, and the wellhead of the water collection well is higher than the upper edge of the primary sedimentation tank.

[0011] According to some embodiments of the present invention, the portion of the water collection well below the water inlet is a secondary sedimentation tank. The secondary sedimentation tank is configured to collect and settle the silt and sand that failed to settle in the primary sedimentation tank, and the silt and sand attached to the surface of the sedimentation weir slides into the secondary sedimentation tank.

[0012] According to some embodiments of the present invention, the sedimentation weir includes a weir plate, side plates, a rotating central shaft, and a locking device. The rotating central shaft is rotatably disposed at the lower edge of the inlet. The weir plate is disposed on the rotating central shaft. The side plates are disposed on both sides of the weir plate. The locking device is disposed on the side plates. The locking device is configured to fix the relative position of the weir plate and the collection well. During flood discharge, the weir plate is tilted.

[0013] According to some embodiments of the present invention, the surface of the weir plate is roughened, and the mud and sand slide down along the roughened surface of the weir plate.

[0014] According to some embodiments of the present invention, a water-retaining weir is provided on the side of the water collection ditch near the green belt or road, and the water-retaining weir is configured to prevent water flow from crossing the water collection ditch.

[0015] According to some embodiments of the present invention, a steel grating is provided on the top of the water collection well, and the steel grating is configured to filter dead branches and fallen leaves in the water flow.

Detailed Implementation

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 5 This utility model discloses an intensive flood interception ditch, including a water conveyance channel 10, a water collection ditch 20, a water collection well 30, and a sedimentation weir 40. The water conveyance channel 10 is buried underground, and an inlet 11 is provided at the side end of the water conveyance channel 10. The water collection ditch 20 is located on one side of the water conveyance channel 10, with one side being a mountain or slope and the other side being a green belt or road. The water collection well 30 is located in the water collection ditch 20, and water flows from the water collection ditch 20 into the water collection well 30. The middle part of the water collection well 30 is connected to the inlet 11, and the lower edge of the inlet 11 is higher than the lowest point of the water collection well 30. The lower end of the sedimentation weir 40 is hinged to the lower edge of the inlet 11. After the water flows into the inlet 11, it rises along the sedimentation weir 40, crosses the sedimentation weir 40, and enters the water conveyance channel 10.

[0030] Understandably, the function of the water conveyance canal 10 is to ultimately collect rainwater and transfer it to prevent urban flooding;

[0031] The drainage ditch 20 is set at the junction of the mountain, slope and other places with elevation differences and the road or greening. Its function is to collect rainwater in the lower-lying areas and prevent rainwater from accumulating in the low-lying areas and causing waterlogging.

[0032] The function of the water collection well 30 is to further collect the rainwater from the water collection ditch 20 and transfer it to the water conveyance canal 10;

[0033] The sedimentation weir 40 can block the lower end of the inlet 11, so that rainwater cannot directly enter the water conveyance channel 10 from the lower end of the inlet 11. Instead, when the water level in the collection well 30 rises above the upper edge of the inclined sedimentation weir 40, it will naturally flow into the water conveyance channel 10. In this way, the mud and sand in the water flow will not enter the water conveyance channel 10 with the water flow, but will settle at the bottom of the collection well 30 under the action of gravity.

[0034] Understandably, by moving the water conveyance canal 10, which has the largest footprint, underground, the bottom-up construction of the water conveyance canal 10 can significantly reduce the land area occupied by the flood channel and reduce the planning difficulty. At the same time, the water collection well 30 and the water collection ditch 20 can be transported and installed after being manufactured in the factory. The civil engineering work of the water conveyance canal 10 and the manufacturing work of the water collection well 30 and the water collection ditch 20 can be carried out simultaneously, which greatly improves the construction efficiency.

[0035] Reference Figure 5 The cross-section of the water collection ditch 20 is V-shaped, and the water collection well 30 is located at the lowest point of the water collection ditch 20.

[0036] Understandably, the V-shaped drainage ditch 20 allows rainwater to eventually collect at the location of the drainage well 30 and be transported to the water conveyance channel 10 through the drainage well 30.

[0037] Reference Figure 5 A primary sedimentation tank 50 is provided around the water collection well 30. The primary sedimentation tank 50 is located in the water collection ditch 20. The wellhead of the water collection well 30 is higher than the upper edge of the primary sedimentation tank 50.

[0038] It is worth noting that in some embodiments of this utility model, before the rainwater in the collection ditch 20 enters the collection well 30, it will enter the primary sedimentation tank 50 around the collection well 30. After the water level in the primary sedimentation tank 50 rises above the wellhead of the collection well 30, it enters the collection well 30, so that some of the mud and sand in the collection ditch 20 will settle in the primary sedimentation tank 50, reducing the amount of mud and sand entering the collection well 30 and avoiding clogging of the collection well 30.

[0039] Reference Figure 2 and Figure 5 The portion of the water collection well 30 below the water inlet 11 is the secondary sedimentation tank 60. The secondary sedimentation tank 60 is configured to collect the silt and sand that failed to settle in the primary sedimentation tank 50. The silt and sand attached to the surface of the sedimentation weir 40 slides into the secondary sedimentation tank 60.

[0040] It is worth noting that the sedimentation weir 40 can block the lower end of the inlet 11, so that rainwater cannot directly enter the water conveyance channel 10 from the lower end of the inlet 11. Instead, when the water level in the collection well 30 rises above the upper edge of the inclined sedimentation weir 40, it will naturally flow into the water conveyance channel 10. In this way, the mud and sand in the water flow will not enter the water conveyance channel 10 with the water flow, but will settle in the secondary sedimentation tank 60 under the action of gravity.

[0041] Reference Figure 3The sedimentation weir 40 includes a weir plate 41, side plates 42, a rotating central shaft 43, and a locking device 44. The rotating central shaft 43 is rotatably mounted on the lower edge of the inlet 11. The weir plate 41 is mounted on the rotating central shaft 43. The side plates 42 are mounted on both sides of the weir plate 41. The locking device 44 is mounted on the side plates 42. The locking device 44 is configured to fix the relative position of the weir plate 41 and the collection well 30. During flood discharge, the weir plate 41 is tilted.

[0042] It should be noted that, in the embodiments of this utility model, the locking device 44 can be attached to the water collection well 30 or other fixed facilities and fix the weir plate 41 in an inclined state. The two sets of side plates 42 and the weir plate 41 form a channel with the side opening facing the water collection well 30 and the upper opening. The upper opening is located in the water conveyance channel 10. When the water level rises above the upper edge of the weir plate 41, the rainwater enters the water conveyance channel 10 and is discharged away.

[0043] It should be noted that when the locking device 44 is released, the weir plate 41 can be flipped. When the operator flips the weir plate 41, the side of the weir plate 41 away from the rotation axis 43 is placed on the bottom of the water conveyance channel 10. At this time, the side plate 42 can be used as a handrail.

[0044] It should be noted that in some embodiments of this utility model, the surface of the weir plate 41 is roughened, and the mud and sand slide down along the roughened surface of the weir plate 41.

[0045] It should be noted that because the weir plate 41 is inclined, some mud and sand will still remain on the weir plate 41 due to friction. In this embodiment, the surface of the weir plate 41 is roughened with the roughening direction downward. The roughening treatment can guide the mud and sand to slide down into the secondary sedimentation tank 60. During maintenance, the roughened surface can also prevent slippage and protect maintenance personnel.

[0046] Reference Figure 2 A weir 70 is provided on the side of the drainage ditch 20 near the green belt or road. The weir 70 is configured to prevent water from flowing over the drainage ditch 20.

[0047] It is worth noting that when the water flow is too rapid, some rainwater may directly cross the drainage ditch 20 and enter the green belt or road under the influence of potential energy. The weir 70 can block this part of the rainwater and allow it to enter the drainage ditch 20.

[0048] Reference Figure 2 The top of the water collection well 30 is equipped with a steel grating 31, which is configured to filter dead branches and fallen leaves in the water flow.

[0049] Understandably, the steel grating 31 can prevent dead branches and fallen leaves from entering the water collection well 30, and it can also be opened to allow maintenance personnel to enter during maintenance.

[0050] It should be noted that in some embodiments of this utility model, a water level gauge is provided on the inner wall of the water collection well 30, which is used to indicate the water level in the well.

[0051] Understandably, the presence of water level gauges allows staff to easily check water levels and adjust drainage strategies in a timely manner.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
