Abstract

This utility model discloses a stormwater drainage system for high-fill roadbeds, relating to the field of stormwater drainage technology. It includes stormwater pipes and inspection wells. Each inspection well comprises a foundation, well base, well cylinder, cast-in-place cylinder, pressure-bearing ring, and well cover. A guide channel is located at the center of the top surface of the upper boss. The inner cavity of the stormwater pipe is connected to the guide channel. The inspection well also includes a receiving bucket and a guide assembly. The guide assembly guides the stormwater flowing in from the well cover to the receiving bucket. The receiving bucket is used for sediment settling in the stormwater. The receiving bucket is press-fitted to the edge of the top surface of the upper boss. The inner wall of the well cylinder, away from the receiving bucket, is rotatably connected to the top of the guide assembly. The guide assembly can rotate until its bottom end overlaps the top of the receiving bucket. Stormwater flowing in from the well cover flows along the guide assembly into the receiving bucket, where sediment settles, before overflowing into the guide channel and stormwater pipe, preventing sediment from entering the stormwater pipe and thus avoiding blockage.

Description

Technical Field

[0001] This utility model relates to the field of rainwater pipe network technology, specifically to a rainwater pipe network system for high embankment roadbeds. Background Technology

[0002] The construction of stormwater drainage networks is a crucial part of municipal road engineering, especially the construction of high embankment subgrades. It can further improve the overall drainage effect of municipal road engineering, prevent the accumulation of rainwater under the foundation, and thus avoid adverse effects on the foundation stability of high embankment subgrades.

[0003] Stormwater drainage systems consist of stormwater pipes and manholes. Manholes are installed to facilitate regular inspection, cleaning, and maintenance of the stormwater drainage system. The manhole covers have permeable holes through which rainwater can flow into the manhole. However, rainwater contains sediment; if this sediment flows into the stormwater pipes through the manholes and accumulates, it can cause blockages. Summary of the Invention

[0004] In order to overcome the problem in the above-mentioned background technology that "the rainwater flowing into the inspection well contains silt, and the accumulation of silt will cause the rainwater pipe to be blocked", this utility model provides a rainwater pipe network system for high embankment roadbed.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0006] A stormwater drainage system for high embankment roadbeds includes stormwater pipes and manholes buried in trenches, wherein the stormwater pipes and manholes are connected and communicate with each other; each manhole includes a foundation, a manhole base above the foundation, a manhole cylinder above the manhole base, a casting cylinder above the manhole cylinder, a pressure-bearing ring above the casting cylinder, and a manhole cover installed on the top of the inner cavity of the pressure-bearing ring; the bottom of the inner cavity of the manhole base is provided with an upper boss, and a guide groove is provided at the middle of the top surface of the upper boss; the stormwater pipes are fixedly connected to the side wall of the manhole base, and the inner cavity of the stormwater pipes communicates with the guide groove; The inspection well also includes a water receiving bucket and a flow guiding assembly. The flow guiding assembly is used to guide rainwater flowing in from the well cover into the water receiving bucket. The water receiving bucket is used for the sedimentation of silt in the rainwater. The water receiving bucket is pressed and disposed at the edge of the top surface of the upper protrusion. The inner side wall of the well shaft away from the water receiving bucket is rotatably connected to the top of the flow guiding assembly. The flow guiding assembly can rotate until its bottom end overlaps the top of the water receiving bucket. The water receiving bucket is provided with a first side plate, the top of which can support the bottom end of the flow guiding assembly. The top of the first side plate is provided with a flow guiding recess.

[0007] As a further optimization of this utility model, the middle part of the flow guiding component can be bent.

[0008] As a further optimization of this utility model, the flow guiding component includes a first plate and a second plate; the top end of the first plate is rotatably connected to the wellbore, and the bottom end of the first plate is rotatably connected to the top end of the second plate via a rotating shaft; a torsion spring is sleeved on the outer periphery of the rotating shaft, and the two ends of the torsion spring are respectively connected to the first plate and the second plate.

[0009] As a further optimization of this utility model, a pull rod is provided at the bottom end of the top surface of the first plate. The pull rod has an n-shaped structure and both ends are fixedly connected to the first plate. A hanging ring is sleeved on the outer periphery of the middle part of the pull rod. The hanging ring is connected to one end of the pull rope, and the end of the pull rope away from the hanging ring is connected to the pull ring.

[0010] As a further optimization of this utility model, a ladder is provided on the inner wall of the pouring cylinder near the receiving bucket.

[0011] As a further optimization of this utility model, the top surface of the upper boss is provided with a staircase for clamping and limiting the receiving bucket, and the staircase is placed between the receiving bucket and the guide channel.

[0012] As a further optimization of this utility model, the staircase is placed below the ladder.

[0013] As a further optimization of this utility model, the bottom of the guide channel is provided with an inclined bottom surface.

[0014] As a further optimization of this utility model, the ladder includes several metal rods, which are U-shaped; the ends of the metal rods are fixedly connected to the well shaft.

[0015] As a further optimization of this utility model, several of the metal rods are arranged vertically in a linear array.

[0016] In summary, this utility model has at least one of the following advantages:

[0017] (1) In this utility model, the inspection well is provided with a flow guiding component that is set in an inclined position; the rainwater flowing in through the well cover flows into the receiving bucket along the flow guiding component and achieves sedimentation, and then overflows into the flow guiding channel and rainwater pipe, so as to avoid sediment from flowing into the rainwater pipe and thus avoid the problem of sediment clogging the rainwater pipe.

[0018] (2) When it rains heavily, the user opens the manhole cover and a large amount of water flows into the inspection well. Water accumulates in the space between the diversion component and the inner wall of the well, and the water level continues to rise. When the weight of the water in the space between the diversion component and the inner wall of the well exceeds the bearing capacity of the diversion component, the middle part of the diversion component automatically bends downward, causing the bottom of the diversion component to separate from the water receiving bucket. Then the diversion component is fully opened to improve the drainage speed.

[0019] (3) The staircase is located below the ladder; when the user enters the inspection well via the ladder, both feet can first step on the staircase and then step on the upper protrusion; thus avoiding the problem of the user jumping down and directly stepping on the upper protrusion and slipping.

[0020] (4) The top of the first side plate of the receiving bucket is provided with a flow guide hole; when the bottom end of the flow guide component is pressed against the top of the first side plate, the rainwater in the inner cavity of the receiving bucket can still overflow through the flow guide hole, avoiding being blocked by the flow guide component.

[0021] (5) A water guide channel is provided on the side of the staircase. The top of the water guide channel is located directly below the guide hole, and the bottom of the water guide channel points towards the guide channel. Rainwater in the water bucket overflows through the guide hole and then flows through the water guide channel into the guide channel. It does not flow over the surface of the staircase, thereby keeping the staircase surface as dry as possible and reducing the slipperiness of the staircase surface (for example, a dry environment will reduce the amount of moss as much as possible), thereby improving the safety of people stepping on the staircase and reducing the risk of slipping.

[0050] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0051] Reference Figures 1-2This embodiment provides a stormwater drainage network system for high embankment roadbeds, including a stormwater pipe 1 and a manhole 2 buried in a trench 3, wherein the stormwater pipe 1 and the manhole 2 are connected and interconnected.

[0052] Reference Figures 1-2 The inspection well 2 includes a foundation 21, a well seat 22 set above the foundation 21, a well cylinder 23 set above the well seat 22, a casting cylinder 24 set above the well cylinder 23, a pressure ring 25 set above the casting cylinder 24, and a well cover 26 installed on the top of the inner cavity of the pressure ring 25.

[0053] Reference Figures 1-2 The foundation 21 is located at the bottom of the trench 3 and is cast in place; the foundation 21 is a reinforced concrete structure. The manhole base 22 and manhole cylinder 23 are both reinforced concrete structures, and are prefabricated and cast integrally in the factory for a fixed connection; the manhole base 22 is fixedly connected to the foundation 21 (e.g., by integral casting with reinforced concrete). The casting cylinder 24 and the pressure ring 25 are both reinforced concrete structures, cast in place; the manhole cover 26 includes a circular cover plate and a circular load-bearing frame (i.e., manhole ring), with a circular groove at the top of the inner cavity of the load-bearing frame, and the edge of the cover plate pressed into the circular groove; the load-bearing frame is fixedly connected to the pressure ring 25 (e.g., by expansion bolts).

[0054] The cover plate is equipped with permeable holes, allowing rainwater to flow into the manhole 23, manhole base 22, and rainwater pipe 1, thus achieving drainage. During heavy rain, users can (using a crane) remove the cover plate from the slot to open the manhole cover 26, allowing accumulated water to flow directly into the manhole 23, manhole base 22, and rainwater pipe 1 through the load-bearing frame, thereby accelerating drainage and preventing urban flooding.

[0055] Reference Figures 3-5 The bottom of the inner cavity of the manhole base 22 is provided with an upper boss 221, which is fixedly connected to the manhole base 22 (e.g., by integral concrete casting). A guide channel 222 is provided at the center of the top surface of the upper boss 221. The rainwater pipe 1 is fixedly connected to the side wall of the manhole base 22 (e.g., by integral reinforced concrete casting), and the inner cavity of the rainwater pipe 1 is connected to the guide channel 222. The same manhole base 22 is connected to two rainwater pipes 1 on the left and right sides respectively. The two rainwater pipes 1 are located on the left and right sides of the manhole base 22, thereby realizing the transportation of rainwater. The bottom of the guide channel 222 is provided with an inclined bottom surface 2221, which is used to allow the rainwater in the guide channel 222 to flow in one direction.

[0056] by Figure 3Taking the perspective shown as an example: the right end of the rainwater pipe 1 on the left is connected to the left end of the guide channel 222, the left end of the rainwater pipe 1 on the right is connected to the right end of the guide channel 222, the left end of the inclined bottom surface 2221 is higher than the right end, and the height of the rainwater pipe 1 on the left is higher than the height of the rainwater pipe 1 on the right, so the rainwater can flow from left to right.

[0057] Reference Figures 6-7 The inspection well 2 also includes a water receiving bucket 27 and a flow guiding component 28. The flow guiding component 28 is used to guide the rainwater flowing in from the well cover 26 into the water receiving bucket 27; the water receiving bucket 27 is used for the settling of mud and sand in the rainwater.

[0058] Reference Figure 6 The receiving bucket 27 is press-fitted to the edge of the top surface of the upper boss 221; the inner wall of the well shaft 23 away from the receiving bucket 27 is rotatably connected to the top of the guide assembly 28; the guide assembly 28 can rotate until its bottom end overlaps the top of the receiving bucket 27. When the bottom end of the guide assembly 28 overlaps the top of the receiving bucket 27, the guide assembly 28 is inclined, and the end of the guide assembly 28 near the receiving bucket 27 is inclined downward. Rainwater falling from the well cover 26 falls onto the guide assembly 28, and then flows along the upper surface of the guide assembly 28 into the receiving bucket 27 (the mud and sand in the rainwater settle in the receiving bucket 27). The rainwater at the top of the inner cavity of the receiving bucket 27 overflows and falls onto the upper surface of the upper boss 221. The overflowing rainwater is finally discharged through the guide channel 222 and the rainwater pipe 1. In this invention, rainwater falling from the manhole cover 26 first flows through the receiving bucket 27 to settle, and then flows into the guide channel 222, thereby collecting sediment in the receiving bucket 27 and preventing sediment from clogging the guide channel 222 and the rainwater pipe 1. Users periodically remove the receiving bucket 27 from the inspection well 2, clean out the sediment inside (for example, by emptying the sediment from the receiving bucket 27 into a nearby flower bed), and then place it back on the upper boss 221.

[0059] Reference Figure 7 When the diversion component 28 is not attached to the receiving bucket 27, it hangs down naturally. At this time, the user can enter the inner cavity of the well base 22 and stand on the upper protrusion 221 to carry out inspection, cleaning (including the operation of removing the receiving bucket 27) and maintenance.

[0060] Reference Figure 6 and Figure 15 The water receiving bucket 27 has a first side plate 271 on the side away from the well base 22. The top of the first side plate 271 can support the bottom of the flow guiding component 28. The top of the first side plate 271 has a flow guiding recess 272. When the bottom of the flow guiding component 28 is pressed against the top of the first side plate 271, the rainwater in the inner cavity of the water receiving bucket 27 can still overflow through the flow guiding recess 272, avoiding being blocked by the flow guiding component 28.

[0061] Reference Figure 8 and Figure 9 The middle part of the flow guide component 28 can be bent (under tension or pressure) and can spring back.

[0062] Reference Figure 9 When the bottom end of the flow guide component 28 is pressed onto the water receiving bucket 27, the user can press the middle part of the flow guide component 28 downwards, causing the flow guide component 28 to bend downwards and detach the bottom end of the flow guide component 28 from the water receiving bucket 27; then the flow guide component 28 will hang down naturally (see reference). Figure 7 This allows the inner cavity of the well base 22 to be opened, enabling personnel to enter the inner cavity and stand on the upper protrusion 221. A ladder 231 is located on the inner wall of the pouring cylinder 24 near the receiving bucket 27. Personnel open the well cover 26, then press down the middle of the guide assembly 28 (e.g., by using a long stick to push it downwards) until it detaches from the receiving bucket 27. Afterwards, by grasping the ladder 231 with both hands and stepping on it, they can enter the well cylinder 23 from top to bottom and stand on the upper protrusion 221, facilitating inspection, cleaning, and maintenance of the inspection well 2. During heavy rain, when the user opens the manhole cover 26, a large amount of water flows into the inspection well 2. (Due to the untimely drainage of the guide hole 272, water accumulates in the space between the guide component 28 and the inner wall of the well cylinder 23, and the water level continues to rise. When the weight of the water in the space between the guide component 28 and the inner wall of the well cylinder 23 exceeds the bearing capacity of the guide component 28, the middle part of the guide component 28 automatically bends downward (driven by the weight of the water), causing the bottom end of the guide component 28 to detach from the water receiving bucket 27. Then the guide component 28 is fully opened to improve the drainage speed.

[0063] Reference Figure 8 , Figure 9 , Figure 11 and Figure 12 The flow guiding assembly 28 includes a first plate 281 and a second plate 282. The top end of the first plate 281 is rotatably connected to the well shaft 23 (e.g., via a hinge), and the bottom end of the first plate 281 is rotatably connected to the top end of the second plate via a rotating shaft. A torsion spring 2811 is sleeved on the outer periphery of the rotating shaft, and both ends of the torsion spring 2811 are connected to the first plate 281 and the second plate 282, respectively. The two ends of the torsion spring 2811 are respectively inserted into the insertion holes on the end face of the first plate 281 and the second end face; the torsion spring 2811 drives the first plate 281 and the second plate 282 to rotate to a coplanar state, thereby realizing the rebound of the flow guiding assembly 28.

[0064] Reference Figure 13A pull rod 283 is provided at the bottom end of the top surface of the first plate 281. The pull rod 283 has an n-shaped structure and both ends are fixedly connected to the first plate 281 (e.g., by bolts). A hanging ring 284 is sleeved on the outer periphery of the middle part of the pull rod 283. The hanging ring 284 is connected to one end of the pull rope 285 (e.g., by binding). The end of the pull rope 285 away from the hanging ring 284 is connected to the pull ring 286 (e.g., by binding). (Refer to...) Figure 8 and Figure 13 The user pulls the pull ring 286 upwards, which indirectly pulls the middle of the flow guide component 28 upwards, causing the bottom end of the flow guide component 28 (i.e., the bottom end of the second plate 282) to engage between the top of the receiving bucket 27 and the bottom end of the well shaft 23. The user then releases the pull ring 286, allowing the bottom end of the flow guide component 28 (i.e., the bottom end of the second plate 282) to naturally overlap the top of the receiving bucket 27 under its own weight, achieving an angled overlap of the flow guide component 28. After completing the work inside the inspection well 2, the user holds the pull ring 286 (or puts the pull ring 286 on their finger), climbs out of the inspection well 2, and then pulls the rope 285 upwards until the bottom end of the flow guide component 28 overlaps the receiving bucket 27; then the user throws the pull ring 286 back into the inspection well 2 and fastens the well cover 26.

[0065] Reference Figure 14 The upper boss 221 has a staircase 223 on its top surface for clamping and limiting the water receiving bucket 27. The staircase 223 is positioned between the water receiving bucket 27 and the guide channel 222. The staircase 223 is a reinforced concrete structure and is integrally fixed to the upper boss 221 through concrete pouring, thereby clamping the water receiving bucket 27 and preventing it from tipping over. The lower part of the water receiving bucket 27 is engaged in a groove between the staircase 223 and the inner wall of the well base 22. Users can lift the water receiving bucket 27 upwards until it is pulled out of the groove; users can also lower the water receiving bucket 27 until it is engaged in the groove.

[0066] Reference Figure 2 and Figure 10 The ladder 231 includes several metal rods 2311, which are U-shaped. Some of the metal rods 2311 are fixedly connected to the well shaft 23 (e.g., anchored), some are fixedly connected to the casting cylinder 24 (e.g., anchored), and some are fixedly connected to the pressure ring 25 (e.g., anchored). The metal rods 2311 are arranged vertically in a straight array to facilitate personnel access to and from the inspection well 2.

[0067] Reference Figure 8 and Figure 14The staircase 223 is located below the climbing ladder 231. When users enter the inspection well 2 via the climbing ladder 231, they can step on the staircase 223 with both feet and then step on the upper protrusion 221; thus avoiding the danger of users jumping down and stepping directly on the upper protrusion 221 (the surface of the upper protrusion 221 is slippery, and users jumping down and stepping on the upper protrusion 221 will risk slipping; if users slip, they will risk hitting the inner wall of the well base 22 and getting injured).

[0068] Reference Figure 16 The staircase 223 has a side-mounted water guide channel 224, with its top end directly below the guide hole 272 and its bottom end pointing towards the guide channel 222. The height of the water guide channel 224 is lower than the height of the staircase 223. Rainwater collected in the water bucket 27 overflows through the guide hole 272 and then flows through the water guide channel 224 into the guide channel 222, preventing it from flowing over the surface of the staircase 223. This keeps the surface of the staircase 223 as dry as possible, reducing its slipperiness (for example, a dry environment minimizes the amount of moss), thereby improving the safety of people walking on the staircase 223 and reducing the risk of slipping.

[0069] Reference Figure 14 and Figure 16 A gap inevitably forms between the outer wall of the water receiving bucket 27 and the inner wall of the staircase 223; rainwater overflowing from the water receiving bucket 27 will fill the gap and then overflow into the water channel 224.

[0070] Reference Figure 17 A filling structure is provided between the inspection well 2 and the trench 3. The filling structure includes a backfill soil layer 4, a backfill concrete layer 5, a roadbed layer 6, a concrete layer 7, and an asphalt layer 8. The backfill soil layer 4 is located on the outer periphery of the bottom of the inspection well, and the backfill concrete layer 5 is located on the outer periphery of the top of the well base 22 and the outer periphery of the bottom of the well cylinder 23; thereby improving the load-bearing capacity at the connection between the well cylinder 23 and the well base 22. The top surface of the backfill soil layer 4 is coplanar with the top surface of the backfill concrete layer 5. The roadbed layer 6 is laid on top of the backfill soil layer 4 and the backfill concrete layer 5, the concrete layer 7 is laid on top of the roadbed layer 6, and the asphalt layer 8 is laid on top of the concrete layer 7. The top surface of the asphalt layer 8 is flush with the top surface of the asphalt layer 8; the pressure ring 25 and the casting ring are embedded in the concrete layer 7; the top of the well cylinder 23 is placed in the concrete layer 7, the middle part is placed in the roadbed layer 6, and the bottom end is placed in the backfill concrete layer 5.

[0071] This utility model has a simple structure and reliable function. The inspection well 2 is equipped with an inclined guide component 28. Rainwater flowing in through the well cover 26 flows along the guide component 28 into the receiving tank 27, where sediment settles (since sediment is denser than water, rainwater dripping into the receiving tank 27 causes sediment to settle, and water flows laterally until overflowing). The overflow then flows into the guide channel 222 and the rainwater pipe 1, preventing sediment from entering the rainwater pipe 1 and thus avoiding silt blockage. Regular cleaning of the receiving tank 27 by users allows this utility model to operate for extended periods.

[0072] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation 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.

[0073] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly.
