Description

Technical Field

[0001] The utility model relates to the field of highway drainage facilities, in particular to a highway drainage structure which is convenient for collecting dirt. Background Art

[0002] When encountering precipitation or other water conditions, if water accumulates on the road, vehicles traveling on the road on rainy days are prone to slipping or even losing control, which can lead to traffic accidents and threaten the personal safety of passengers. Therefore, drainage facilities must be installed on both sides of the highway to drain the water accumulated on the road. The road drainage facilities are used to discharge the water accumulated on the road into the drainage channel for discharge. Generally, when the accumulated water is discharged into the drainage channel, it will carry dirt, fallen leaves or garbage to block the coarse grille at the drainage channel outlet, or enter the drainage channel to cause siltation and blockage of the drainage channel, resulting in the inability to discharge the accumulated water smoothly, resulting in flooding of the road surface. In addition, when cleaning the dirt, there are problems such as the inconvenience of collecting road dirt and the difficulty of cleaning the drainage channel dirt.

[0003] A Chinese patent (Announcement No.: CN 220080226 U) discloses a drainage pipeline, in which a collection box is arranged on both sides of a sewer, and a first filter screen is arranged in the sewer. While the sewage entering the sewer is filtered by the first filter screen, the blocked dirt is guided to the collection box for temporary storage. The temporarily stored impurities can be discharged through the second filter screen on the side to return the remaining sewage to the sewer. After the collection box is filled with dirt, the collection box can be drawn out from the storage box for cleaning, which is convenient for collecting road dirt and cleaning drainage dirt. However, the second filter screen is arranged on the side of the collection box, and the sewage retained on the side of the collection box away from the second filter screen is difficult to pass through the collected dirt to flow to the second filter screen, resulting in the residue of sewage in the collection box, resulting in the high water content of the dirt in some areas of the collection box, which cannot be dried in time, and is easy to cause decay and odor; at the same time, the residual sewage also increases the weight of the collection box, increasing the difficulty of drawing out the collection box for cleaning.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] Traditional highway drainage wells are prone to poor drainage or even blockage due to the accumulation of dirt and garbage. The current dirt collection box used for drainage wells cannot effectively remove the residual moisture inside, causing the dirt to remain wet for a long time, which is prone to rotting and odor. In addition, due to the high humidity of the dirt, it increases the difficulty and time consumption of cleaning. Based on this, this embodiment provides a highway drainage structure that is convenient for collecting dirt. The collection box 2 is arranged on one side of the drainage channel 11 to collect the dirt filtered out of the drainage channel 11. A second filter screen 9 is provided at the bottom of the collection box 2 to discharge the residual moisture of the dirt in the collection box 2 with the assistance of gravity, reduce the humidity of the dirt in the collection box 2, thereby reducing the rotting and odor problems, and can reduce the weight of the collection box 2, which is convenient for the extraction and cleaning process of the collection box 2.

[0028] See also Figure 1 The highway drainage structure for collecting waste mainly includes a drainage channel 11, a placement trough 8 and a collection box 2, wherein the drainage channel 11 and the placement trough 8 are both fixed structures arranged on the road body 1, the drainage channel 11 and the placement trough 8 are spaced apart, the drainage channel 11 and the placement trough 8 are connected through a slag inlet channel, and are also connected through a water collecting hopper 10 and a water collecting channel, the collection box 2 can be inserted into the placement trough 8 to collect waste, and the waste can enter the collection box 2 accommodated in the placement trough 8 through the slag inlet channel, and a filter is provided at the bottom of the collection box 2, which can discharge the residual sewage entrained by the collected waste and return it to the drainage channel 11 through the water collecting hopper 10 and the water collecting channel; the collection box 2 can be drawn out from the placement trough 8 to remove the waste inside the collection box 2.

[0029] Specifically, an inclined first filter screen 6 is provided inside the drain channel 11. The first filter screen 6 can be fixed on the inner wall of the drain channel 11, and can effectively intercept dirt to ensure smooth drainage. The inclination angle of the first filter screen 6 relative to the horizontal plane can be 15°-30°. It is understandable that other inclination angles can also be used, and they can be configured and selected according to filtering requirements. A return port is provided on the side of the drain channel 11 below the first filter screen 6, so that the residual water discharged from the collection box 2 can flow back to the drain channel 11 through this return port. The drain channel 11 can be connected to the municipal pipeline to discharge the collected water into the municipal pipeline.

[0030] The drainage channel 11 and the placement groove 8 are respectively opened on the road body 1, and can be reserved during the municipal road construction. The drainage channel 11 can be used as a rainwater well, and the placement groove 8 provides a stable placement position for the collection box 2. The bottom of the placement groove 8 is connected to the return water port through the water collecting bucket 10 and the water collecting channel, providing a return channel for the residual water filtered out by the collection box 2, reducing the residual water in the collection box 2.

[0031] A slag inlet 7 is provided on the side of the collecting box 2, and the slag inlet 7 can be connected to the area above the first filter 6 in the drain 11 to ensure that the dirt can smoothly enter the collecting box 2. At the same time, the inclined first filter 6 can effectively intercept the dirt and keep the drain 11 unobstructed. The lower end of the inclined first filter 6 is located on the side close to the slag inlet 7. The inclined arrangement of the first filter 6 is not only conducive to the natural separation of dirt and water flow and improves the filtering effect, but also can guide the filtered dirt to facilitate the dirt to enter the collecting box 2 for collection and temporary storage.

[0032] A second filter screen 9 is provided at the bottom of the collecting box 2 and is connected to the opening of the water collecting bucket 10, so that the residual moisture of the dirt in the collecting box 2 is collected to the bottom of the collecting box 2 under the action of gravity, passes through the second filter screen 9 and enters the water collecting bucket 10, and then flows back to the drain 11 through the water collecting bucket 10, the water collecting channel and the return water outlet, thereby reducing the humidity of the dirt in the collecting box 2, improving the dryness, and reducing the problems of decay and odor.

[0033] In addition, due to the reduction in the humidity of the dirt, the weight of the collection box 2 and the dirt inside is also effectively reduced, the cleaning work becomes simpler and more efficient, and the difficulty and time consumption of cleaning are reduced.

[0034] The drainage channel 11 and the placement trough 8 are arranged at intervals, and a shoulder 4 is provided between the two. A slag inlet channel connecting the slag inlet 7 and the area above the first filter screen 6 is provided below the shoulder 4. The slag inlet channel provides a channel for debris to enter the collection box 2. The design of the shoulder 4 ensures driving safety and maintains the interval between the drainage channel 11 and the placement trough 8 and structural stability.

[0035] The bottom surface of the slag inlet channel is coplanar with the plane where the first filter screen 6 is located, so that the debris filtered out by the first filter screen 6 can smoothly pass through the junction of the slag inlet channel and the first filter screen 6, thereby improving the efficiency of collecting debris and reducing resistance.

[0036] A drain grate 5 is installed at the top opening of the drain channel 11, and the first filter screen 6 and the drain grate 5 are vertically spaced apart, and the mesh size of the drain grate 5 is larger than the mesh size of the first filter screen 6; the drain grate 5 serves as the first layer of protection to intercept large particles of debris, which are further filtered by the first filter screen 6, thereby improving the overall filtering effect and ensuring the smooth flow of the drain channel 11.

[0037] In this embodiment, the size and material of the drainage grate 5 can be selected according to the needs, including but not limited to: size specifications: 300mm×500mm, 400mm×500mm, 400mm×600mm, 500mm×500mm, etc. Thickness specifications: 20mm, 30mm, 40mm (applicable to cast iron and stainless steel grates), 25mm, 38mm, 50mm (applicable to glass fiber reinforced plastic grates). The corresponding mesh size can be 30mm×50mm, 40mm×50mm, etc.

[0038] Similarly, the size and material of the first filter screen 6 can be selected according to demand to match the size of the drain channel 11, and the corresponding mesh size can be 25mm×45mm, 35mm×45mm, etc.

[0039] In this embodiment, the drainage grate 5, the first filter screen 6 and the second filter screen 9 are all made of alloy wear-resistant materials to improve their durability.

[0040] like Figure 1 As shown, in the vertical direction, the plane where the top opening of the placement slot 8 is located is above the plane where the top opening of the drainage channel 11 is located, and the placement slot 8 and the drainage channel 11 are adapted to the different height distributions of the road body 1. The top surface of the collection box 2 is flush with the top opening of the placement slot 8. After the collection box 2 is placed in the placement slot 8, the collection box 2 is prevented from protruding from the placement slot 8.

[0041] The top surface of the collecting box 2 is flush with the top opening of the placement slot 8, so that the collecting box 2 can be stably placed in the placement slot 8 without causing installation difficulties or instability due to the height difference. The road surface remains flat at the location of the collecting box 2 and the drain 11, ensuring the safety of vehicles and pedestrians and avoiding safety hazards caused by uneven road surface. By reasonably designing the height of the placement slot 8 and the drain 11, it can be ensured that the entire drainage structure is more visually coordinated and beautiful. The top surface of the collecting box 2 is flush with the top opening of the placement slot 8, reducing the visual abruptness caused by the height difference, allowing the entire drainage structure to be better integrated into the design of the road body 1.

[0042] The top surface of the collection box 2 is detachably connected with a handle 3. The top surface of the collection box 2 may be provided with a threaded hole or other structure, and a corresponding screw may be provided on the handle 3, and the detachable connection between the collection box 2 and the screw is achieved through the cooperation of the threaded hole and the screw. The detachable handle 3 can be removed from the collection box 2 after use, avoiding a bulge on the top surface of the collection box 2, reducing the impact on passers-by and vehicles passing by this position, and improving safety.

[0043] The side wall of the collecting box 2 fits the side wall of the placement slot 8, and a detachable connection is formed between the collecting box 2 and the placement slot 8 by a sliding fit. The sliding fit ensures the stability of the collecting box 2 in the placement slot 8, and is easy to disassemble, clean and maintain.

[0044] like Figure 1 As shown, the bottom surface of the placement groove 8 outside the top opening of the water collecting bucket 10 forms a platform for carrying the collection box 2, ensuring the stability of the collection box 2 in the placement groove 8, and ensuring the bearing capacity of the top surface of the collection box 2, reducing the impact on vehicles and people passing above.

[0045] The water collecting bucket 10 is in a stepped shape, and in the vertical direction, the end of the water collecting bucket 10 with a smaller horizontal cross-sectional area is located at the bottom and connected to the water collecting channel. Figure 1 As shown, the water collecting channel is arranged obliquely, and in the vertical direction, the water collecting bucket 10 and the water collecting channel are located between the second filter screen 9 and the water return port.

[0046] The stepped design makes the horizontal cross-sectional area of ​​the water collecting bucket 10 gradually decrease in the vertical direction, that is, the bottom horizontal cross-sectional area of ​​the water collecting bucket 10 is smaller than the top horizontal cross-sectional area, which is conducive to gradually guiding water from a larger area to a smaller outlet, thereby achieving effective water collection.

[0047] The inclined water collection channel uses the effect of gravity to make the water flow naturally in the channel without the need for additional power support. The inclined design allows the water to form a certain flow rate in the channel, which can accelerate the discharge of water and reduce the retention time in the channel. During the drainage process, the inclined channel can prevent the water from flowing back and ensure the unidirectionality and stability of the drainage process.

[0048] The combination of the terraced water collecting bucket 10 and the inclined water collecting channel forms an optimized water flow path. Water is collected from a larger area to a smaller outlet and then quickly discharged through the inclined channel. The whole process is efficient and stable, which can improve drainage efficiency.

[0049] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
