Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a drainage structure for roadbed slopes and ditches in rural road construction. Background Technology

[0002] Rural roads are often located in areas with complex terrain and varied geological conditions. Cuts or embankments are usually formed on both sides of the road. When it rains, the slopes of the cuts or embankments are eroded by rainwater, resulting in soil erosion and affecting the stability of the slopes, which can lead to landslides or collapses. Therefore, slope and roadbed drainage is very important in the construction of rural roads.

[0003] Slope roadbed drainage structures typically include side ditches at the junction of the roadbed and the slope, with pipes buried in the slope to guide water from the top of the slope into the side ditches for discharge. However, when the slope is too steep and the water flow is rapid, the filter screens in the side ditches are easily damaged, resulting in poor filtration. Larger impurities such as stones and leaves can clog the pipes, affecting the efficiency of water discharge and causing water to overflow onto the road, thus affecting its use. Therefore, a new slope roadbed side ditch drainage structure for rural road construction is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drainage structure for the roadbed slope of rural highway construction, which solves the problem of poor drainage and protection efficiency of the roadbed slope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for the roadbed and ditch of rural road construction, used for installation in the roadbed and slope, comprising:

[0006] A buffer component is provided inside the slope. The buffer component includes a collection unit and a transport unit. The collection unit is used to slow down the water flow and guide the water into the transport unit.

[0007] A transfer component is disposed inside the roadbed. The transfer component includes a transfer unit and a filtration unit. The transfer component is used to receive water flow introduced by the transport unit, and the filtration unit is used to filter the water flow.

[0008] In one embodiment, the transport unit includes multiple transport pipes, which are installed in the slope soil layer, and multiple connecting pipes are fixed and vertically connected to the transport pipes.

[0009] In one embodiment, the collection unit includes multiple buffer platforms set on the slope. Both the buffer platforms and the top of the slope are provided with laying trenches. Inside the laying trenches, there are blind pipes, a layer of crushed stone, and backfill soil. The blind pipes are wrapped with geotextile. The crushed stone layer is wrapped around the geotextile and fills the gaps in the blind pipes. The backfill soil is laid on the crushed stone layer. Multiple connecting pipes are fixed and longitudinally connected to the blind pipes. The blind pipes in each laying trench are connected to the transport pipes through the connecting pipes.

[0010] In one embodiment, the transfer unit includes a side ditch and multiple drainage pipes. The inlets of the drainage pipes are uniformly fixed to and connected to the side ditch, and the drainage pipes are interconnected. The transport pipes pass through and extend into the side ditch.

[0011] In one embodiment, the filtration unit includes a filter screen plate embedded inside the side ditch and blocking the inlet of the drainage pipe. The filter screen plate is connected to the side ditch by a fixing member. Adjusting screws are rotatably installed at both ends of the top of the filter screen plate. A screw head is provided at one end of the adjusting screw. A movable sleeve is installed on the external thread of the adjusting screw. A toothed plate is fixedly installed on the outside of the movable sleeve. The toothed plate is slidably sleeved on the outside of another adjusting screw.

[0012] In one embodiment, a curbstone is provided at the top of the slope, and the curbstone is located between the slope and the paving groove at the top of the slope.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The rural road construction utilizes a slope and roadbed drainage structure. Through the installation of buffer and transfer components, rainwater from the slope is effectively buffered and diverted into the ditch. Then, the filtration unit further buffers and disperses the water flow, preventing large particles from directly damaging the filter screen, avoiding overflow water from affecting road traffic, ensuring smooth drainage pipes, and reducing safety hazards.

[0015] The rural road construction features a slope roadbed and ditch drainage structure. The filter unit can be adjusted to protect the filter screen according to the slope inclination, further ensuring smooth drainage and making the overall structure more flexible in use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment describes a rural road construction slope and subgrade drainage structure, used in the roadbed 1 and slope 2, comprising:

[0024] A buffer component is installed inside the slope 2. The buffer component includes a collection unit and a transport unit. The collection unit is used to slow down the water flow and guide the water into the transport unit.

[0025] The transfer component is located inside the roadbed 1. The transfer component includes a transfer unit and a filtration unit. The transfer component is used to receive the water flow introduced by the transport unit, and the filtration unit is used to filter the water flow.

[0026] In this embodiment, the transportation unit includes multiple transportation pipes 12, which are installed in the soil layer of the slope 2. Multiple connecting pipes 13 are fixed and vertically connected to the transportation pipes 12.

[0027] It should be understood that multiple connecting pipes 13 collect the water flow in the collection unit into the transport pipe 12, thereby preventing the water flow from flowing directly down from the top of the slope 2 and slowing down the water flow rate. At the same time, the water on the slope 2 is collected and introduced into the transport pipe 12 through multiple connecting pipes 13, preventing too much mud, sand and gravel from being carried into the transfer unit.

[0028] In addition, the number of connecting pipes 13 needs to be set according to the actual usage.

[0029] In this embodiment, the collection unit includes multiple buffer platforms 6 set on the slope 2. Both the buffer platforms 6 and the top of the slope 2 are provided with laying grooves 7. Inside the laying grooves 7, there are blind pipes 8, a gravel layer 10 and backfill soil 11. The blind pipes 8 are wrapped with geotextile 9. The gravel layer 10 is wrapped around the geotextile 9 and fills the gaps in the blind pipes 8. The backfill soil 11 is laid on the gravel layer 10. Multiple connecting pipes 13 are fixed and longitudinally connected to the blind pipes 8. The blind pipes 8 in each laying groove 7 are connected to the transport pipes 12 through the connecting pipes 13.

[0030] It should be understood that the setting of multiple buffer platforms 6 slows down the flow of water falling from the top of the slope 2 and the slope. At this time, the water flows through the backfill soil 11 into the gravel layer 10 to filter the mud and sand. Then, the geotextile 9 outside the blind pipe 8 filters the rainwater again, thereby preventing impurities and mud from entering the transfer unit and ensuring the rainwater discharge effect of the transfer unit.

[0031] The blind tube 8 has a porous structure that allows water to permeate quickly. Through capillary action and gravity, water is quickly introduced into the transport tube 12 via the connecting tube 13.

[0032] In this embodiment, the transfer unit includes a side ditch 3 and multiple drainage pipes 4. The inlets of the drainage pipes 4 are uniformly fixed to and connected to the side ditch 3, and the drainage pipes 4 are interconnected. The transport pipe 12 passes through and extends into the side ditch 3.

[0033] It should be understood that the side ditch 3 is an open channel. Although it is easy to maintain, its water flow speed is affected by the slope and roughness (inner wall roughness). On the other hand, the drainage pipe 4 has a smooth inner wall, low roughness, and low water flow resistance. It can maintain a high flow rate at a small slope and quickly discharge large flow of water. The combination of the two makes the drainage effect better.

[0034] In this embodiment, the filter unit includes a filter screen plate 14, which is embedded inside the side ditch 3 and blocks the inlet of the drainage pipe 4. The filter screen plate 14 is connected to the side ditch 3 by a fastener. Adjusting screws 15 are rotatably installed at both ends of the top of the filter screen plate 14. A screw head 16 is provided at one end of the adjusting screw 15. A movable sleeve 18 is threaded on the outside of the adjusting screw 15. A toothed plate 17 is fixedly installed on the outside of the movable sleeve 18. The toothed plate 17 is slidably sleeved on the outside of another adjusting screw 15.

[0035] It should be understood that, when used for drainage of slopes 2 with different slopes, the rotating head 16 can rotate the adjusting screw 15, causing the movable sleeve 18 to operate, thereby driving the toothed plate 17, which is limited by another adjusting screw 15, to move. In this filter unit, the toothed plates 17 on the two adjusting screws 15 are spaced apart, which can drive the spaced toothed plates 17 to move relative to or away from each other, thereby adjusting the gap between the toothed plates 17 to adapt to different water flow rate impacts, so that the filter screen 14 can be flexibly protected.

[0036] In addition, the fasteners are bolts and nuts, which allow the filter screen 14 to be tightly fixed to the side ditch 3. At the same time, the bolts and nuts can be easily disassembled and assembled using an electric screwdriver, making maintenance convenient.

[0037] In this embodiment, a curbstone 5 is provided at the top of the slope 2, and the curbstone 5 is located between the slope of the slope 2 and the paving groove 7 at the top of the slope 2.

[0038] The setting of the curbstone 5 is intended to prevent rainwater from falling from the top of the slope 2 onto the slope 2, allowing the rainwater to be purified by the collection unit. At the same time, it prevents a large amount of rainwater from washing away the slope 2, causing a large amount of gravel and silt to enter the ditch 3, relieving the filtration pressure of the filter screen 14, reducing its wear, and ensuring that the drainage pipe 4 connected to the ditch 3 is unobstructed.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Although embodiments of the present 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 present invention.
