Description

Technical Field

[0001] This invention relates to the field of slope drainage technology, specifically a rotary slope drainage device that facilitates subsequent dredging and maintenance. Background Technology

[0002] Groundwater is a significant factor contributing to slope instability. On one hand, the shear strength of the slope's soil and rock mass decreases when soaked by groundwater; on the other hand, excessively high groundwater levels increase pore water pressure in the soil and rock mass, further reducing its shear strength. In short, the accumulation of groundwater within a slope is detrimental to its stability. Therefore, drainage pipes are typically installed in slope stabilization projects. However, in most cases, after prolonged use, clay deposits easily accumulate at the inlet of these drainage pipes, eventually clogging them and preventing timely drainage of groundwater, which can easily induce slope instability.

[0003] The anti-clogging solutions for slope drainage pipes mainly include two aspects: filtration measures during initial installation and subsequent dredging and maintenance. Filtration measures typically involve installing filter bags at the pipe inlets, but the on-site construction process is complex, and the filter bags are easily damaged by long-term groundwater exposure, leading to clogging failure. Furthermore, most drainage pipe blockages occur at the inlet within the slope, making subsequent dredging difficult and ineffective. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary slope drainage device that facilitates subsequent dredging and maintenance, and can at least solve some of the defects in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotary slope drainage device that facilitates subsequent dredging and maintenance, comprising a water collection tank that can be placed inside the slope, the water collection tank having a cavity and seepage holes on its body, the water collection tank being connected to a first drainage pipe, the inlet end of the first drainage pipe being connected to the water collection tank, a rotating component being rotatably disposed inside the first drainage pipe, an agitator being disposed in the water collection tank capable of stirring up sediment deposits in the cavity, one end of the rotating component extending to the outlet of the first drainage pipe, and the other end of the rotating component being connected to the agitator, the rotating component being a second drainage pipe, the second drainage pipe being rotatably disposed inside the first drainage pipe, the agitator being connected to the inlet end of the second drainage pipe, the agitator including a sheet-like sludge-removing plate, the sludge-removing plate being rotatable around the central axis of the water collection tank, the sludge-removing plate being fixedly connected to the rotating component, the first drainage pipe being detachably connected to the water collection tank, and the water collection tank being a hollow cylinder.

[0006] Furthermore, the second drain pipe and the first drain pipe are connected by a bearing.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8This invention provides a rotary slope drainage device that facilitates subsequent dredging and maintenance. It includes a water collection tank 3 that can be placed within the slope. The water collection tank 3 has a cavity and seepage holes 6 on its body. The water collection tank 3 is connected to a first drainage pipe 1, with the inlet end of the first drainage pipe 1 communicating with the water collection tank 3. A rotating component is rotatably installed inside the first drainage pipe 1. The water collection tank 3 is equipped with an agitator capable of dispersing sediment deposits in the cavity. One end of the rotating component extends to the outlet of the first drainage pipe 1, and the other end is connected to the agitator. In this embodiment, simply rotating the rotating component manually to agitate the sediment deposits in the water collection tank 3 achieves the purpose of dredging and maintenance. Specifically, the water collection tank 3 is placed within the backfill soil 13 of the slope. Groundwater in the soil can enter the water collection tank 3 through the seepage holes 6 and then flow out through the first drainage pipe 1 to the outside of the slope. If sediment accumulates and clogs the water collection tank 3 over time, the rotating and agitating components can be rotated to stir the water and prevent blockages caused by lumpy sediment. Multiple seepage holes 6 can be designed, and their diameters can be customized as needed.

[0028] As an optimized solution for an embodiment of the present invention, please refer to Figures 1 to 8 The rotating component is a second drain pipe 2, which is rotatably disposed inside the first drain pipe 1. The agitator is connected to the inlet end of the second drain pipe 2. In this embodiment, the rotating component can be a second drain pipe 2, forming a double-layer pipe structure with an outer pipe surrounding an inner pipe. The second drain pipe 2 has three functions: first, to drain water; second, to drive the agitator to rotate; and third, to connect to a flushing pipe to flush water into the collection tank. This not only agitates the water in the collection tank 3 but also allows water to be flushed into the collection tank 3 via the flushing pipe, thus solving the blockage at the inlet end and the seepage hole 6. When the rotating component uses the second drain pipe 2, during normal use (i.e., when not sludge removal), the second drain pipe 2 serves as the main drain pipe. Due to the bearing connection between the first drain pipe 1 and the second drain pipe 2, the drainage efficiency through the gap between them is very low. Of course, the rotating component does not necessarily have to be a drain pipe; any structure that can form a flow path can be used. This embodiment does not impose any restrictions on this.

[0029] For further optimization of the above solution, please refer to [link / reference]. Figure 1 , Figure 5 and Figure 6The second drain pipe 2 and the first drain pipe 1 are connected by a bearing 5. In this embodiment, a bearing 5 can be used to connect the first drain pipe 1 and the second drain pipe 2, forming a certain gap between them to prevent them from becoming stuck. This gap also allows water to pass through, but the drainage efficiency is low. The first drain pipe 1 has a locking hole 10, and the bearing 5 is fixed in the locking hole 10. The locking hole 10 can be provided on the first drain pipe 1, and the bearing 5 can be easily installed using a buckle 8. The number of bearings 5 ​​can be set according to the length of the drain pipe. For example, in this embodiment, two bearings 5 ​​are used at intervals. The outlet of the second drain pipe 2 extends beyond the first drain pipe 1, making it convenient for people to hold and rotate the second drain pipe 2.

[0030] As an optimized solution for an embodiment of the present invention, please refer to Figures 1 to 8 The agitator includes a sheet-like sludge-clearing plate 4, which is rotatable around the central axis of the water collection tank 3. The sludge-clearing plate 4 is fixedly connected to the rotating component. In this embodiment, the agitator can be refined into a plate-like structure. When the water collection tank 3 is a hollow cylinder, the width of the sludge-clearing plate 4 is equal to the radius of the hollow cylinder, and the rotation of the sludge-clearing plate 4 can agitate the entire cavity. Of course, in addition to using a plate-like structure, a spiral structure, a paddle structure, etc., can also be used for agitation. Preferably, the sludge-clearing plate 4 is fixed to the rotating component by bolts 12. A first connecting hole 9 is provided on the second drain pipe 2, and a second connecting hole 11 is provided on the sludge-clearing plate 4. The two are connected by bolts 12 to connect the first connecting hole 9 and the second connecting hole 11.

[0031] As an optimized solution for an embodiment of the present invention, please refer to Figure 3 and Figure 4 The tank body has a removable cover plate 7. In this embodiment, when assembling the device, the cover plate 7 can be opened first, and then all components can be installed from the cover plate 7 before the cover plate 7 is reinstalled, which facilitates on-site installation and maintenance. Preferably, the cover plate 7 is the bottom cover of the water collection tank 3.

[0032] As an optimized solution for an embodiment of the present invention, please refer to Figures 1 to 8 The first drain pipe 1 is detachably connected to the water collection tank 3. In this embodiment, the first drain pipe 1 and the water collection tank 3 can also be designed to be detachably connected, for example, by a threaded connection, which facilitates disassembly, replacement, and maintenance.

[0033] As an optimized embodiment of the present invention, the first drain pipe is a PVC pipe, and the water collection tank and the agitator are both made of stainless steel; when a second drain pipe is used, the second drain pipe is also made of PVC pipe.

[0034] As an optimized embodiment of the present invention, the aforementioned rotary slope drainage device, which facilitates subsequent dredging and maintenance, can be used in slopes. The slope also includes a retaining wall 14 with pre-reserved drainage holes. The water collection tank 3 is built into the slope, and the first drainage pipe 1 extends from the inside of the slope through the drainage holes to the outside of the slope. The first drainage pipe 1 is inclined downwards. In this embodiment, the device is used in the slope, and the first drainage pipe 1 is designed to be inclined downwards, which facilitates drainage. In use, the rotating component is manually rotated to drive the agitator to disperse the sediment in the water collection tank 3, thereby achieving the purpose of dredging and maintenance. Specifically, the water collection tank 3 is placed in the backfill soil 13 of the slope. Groundwater in the soil can enter the water collection tank 3 through the seepage holes 6, and then flow out of the slope through the first drainage pipe 1. When sediment accumulates and clogs the water collection tank 3 over time, the rotating component can be rotated, and the agitator can stir the sediment in the water collection tank 3 to prevent blockage caused by lumpy sediment. Multiple seepage holes 6 can be designed, and their diameters can be customized as needed. For better sludge removal, the rotating component can be refined into a second drain pipe 2, which can be connected to a flushing pipe to flush water into the collection tank 3, completely clearing the blockage.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
