Description

Technical Field

[0001] The present invention relates to the field of urban road drainage, and specifically to a concealed drainage system for urban roads. Background Art

[0002] Urban road drainage refers to a series of measures taken to drain the precipitation on the urban road surface, ensuring that the road surface drains quickly and smoothly, avoiding water accumulation and the formation of a water film on the road surface, thereby ensuring driving safety. This process involves multiple components and facilities to ensure the effectiveness and efficiency of the drainage system.

[0003] In traditional drainage systems, grilles are used for drainage. Impurities such as dust, sediment, and dead leaves on the road surface will flow into the drainage device through the grilles. These impurities easily enter the drainage system, increasing the burden on the drainage system. Larger impurities such as leaves are easily stuck in the gaps of the grilles for drainage, making it inconvenient to clean. The impurities will gradually accumulate, resulting in poor drainage, and the installation of grilles at the road affects the aesthetics. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a concealed drainage system for urban roads, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A concealed drainage system for urban roads includes a sewer disposed in the road and a well frame communicated with the sewer. A trough frame and a grille are installed inside the well frame, and a mixture of asphalt and a monomer structure is laid inside the trough frame.

[0006] The monomer structure includes an outer sphere and an inner sphere that can move freely. A number of interconnected channels are opened inside the outer sphere, and the inner sphere is located in the intersection area of the several channels. An activity rod fixed to the inner sphere is provided inside each channel, and a number of circular plates are fixedly installed at the end of the activity rod away from the inner sphere.

[0007] Preferably, a lifting lug is fixedly installed on the upper part of the trough frame, and a lifting hole is provided inside the lifting lug.

[0008] Preferably, a number of notches are opened inside each circular plate.

[0009] Preferably, the outer end of the activity rod is located outside the outer sphere.

[0010] Preferably, the number of activity rods is not less than four.

[0011] Compared with the prior art, the present invention has the following beneficial effects: For this hidden drainage system for urban roads, there is no need to install the grille on the upper part of the asphalt layer. By laying asphalt and several monomer structures together in the trough frame, the road surface is clean and beautiful. Since the surface of the mixture in the trough frame is flat, it is convenient to clean, and it is realized that larger impurities are not easily stuck in the gaps of the grille. It can not only filter larger impurities, prevent impurities from entering the drainage system, and reduce the burden on the drainage system. Through the set monomer structures, there are certain gaps between the asphalt particles and the monomer structures, making the moisture on the road surface easily pass through the mixed layer of the monomer structures and asphalt. While achieving good drainage function, it is clean and beautiful in appearance. When maintenance is required, only the well frame needs to be taken out, and the operation is convenient and fast.

[0022] Such as Figures 1-9As shown in the figure, a concealed drainage system for urban roads includes a sewer installed in the road and a well frame 3 communicated with the sewer. The road includes an asphalt layer 1 and a cement layer 2. A groove frame 4 and a grille 5 are installed inside the well frame 3. A mixture of asphalt and monomer structure is laid inside the groove frame 4. A lifting lug 12 is fixedly installed on the upper part of the groove frame 4. A lifting hole is provided inside the lifting lug 12. The lifting lug 12 is on the same horizontal plane as the asphalt layer 1. The number of the lifting lugs 12 is set to two, and the groove frame 4 is removed through the lifting lugs 12.

[0023] This solution is preferably installed on sidewalks with low drainage requirements, such as sidewalks higher than the road or areas with less rainfall; The monomer structure includes an outer sphere 6 and an inner sphere 7 that can move freely. A number of interconnected channels 8 are opened inside the outer sphere 6. The inner sphere 7 is located in the intersection area of a number of channels 8. An active rod 9 fixed to the inner sphere 7 is provided inside each channel 8, and the active rods 9 are equally spaced around the outer space of the inner sphere 7. The outer end of the active rod 9 is located outside the outer sphere 6. The length of the active rod 9 is not less than the radius of the outer sphere 6. The number of the active rods 9 is not less than four. A number of discs 10 are fixedly installed at one end of the active rod 9 away from the inner sphere 7. A number of notches 11 are opened inside each disc 10. The grille 5 is in close contact with the groove frame 4 and the well frame 3.

[0024] It should be understood that when the number of the active rods 9 is four, the number of the channels 8 should also be four. The active rods 9 need to be vertically corresponding to the channels 8. When the monomer structure is mixed with asphalt particles, when the number of the active rods 9 is set to not less than four, at any angle of the monomer structure, at least one end of an active rod 9 will tilt upward, and gaps will appear in the asphalt around the active rod 9 and the disc 10, increasing the gaps between the asphalt particles, which is beneficial to the discharge of water along the gaps;

[0025] The processing method of the monomer structure is as follows: First, the shapes of the outer sphere 6 and the inner sphere 7 are processed by a mechanical processing device, and the outer sphere 6 is punched to form four interconnected channels 8. Then, one of the active rods 9 is fixed to the inner sphere 7 through a production assembly device, and then the inner sphere 7 is inserted into the middle of the outer sphere 6 along one of the channels 8. It can be fixed by screwing the active rod 9 and the inner sphere 7. The remaining active rods 9 are fixed to the inner sphere 7 in turn. At this time, the four active rods 9 should be respectively located in the four channels 8.

[0026] The size description of the monomer structure: The thickness of the asphalt layer 1 laid in the groove frame 4 is generally 5-12 cm. Therefore, the maximum length of the monomer structure cannot exceed the thickness of the asphalt layer 1. Of course, the monomer structure can be smaller than the thickness of the asphalt layer 1. When the monomer structure is smaller than the thickness of the asphalt layer 1, it is best to make multiple monomer structures in contact with each other to facilitate smooth drainage;

[0027] Therefore, the monomer structure and the asphalt need to be evenly mixed. After the mixed monomer structure and asphalt are laid inside the trough frame 4 and compacted, smooth drainage can be achieved.

[0028] Next, the asphalt is fully mixed and stirred with several monomer structures and then laid together in the trough frame 4, effectively preventing impurities from entering the drainage system along with rainwater. It should be noted that the grille 5 needs to be set at the bottom of the trough frame 4. Since the grille 5 is not exposed on the surface of the asphalt layer 1, it is difficult for impurities to flow into the drainage system together with rainwater. This is because the structural layer formed after the asphalt is mixed with the monomer structures has a filtering effect and can effectively block larger impurities (such as leaves and plastic bags). Even when the road surface is washed by rainwater, it is difficult for larger impurities to break through this layer of protection, thus greatly avoiding the problem of drainage pipe blockage caused by continuous accumulation of impurities and then poor drainage. Secondly, the distance between the monomer structure and the uppermost layer of the asphalt layer 1 is relatively small. After laying, since the movable rod 9 and the disc 10 are between the asphalt at this time, the compactness between the asphalt is reduced and the gap between the asphalt is increased. The movable rod 9 and the disc 10 play a role in separating the asphalt, which is helpful for subsequent drainage work. Moreover, since the asphalt is a non-rigid material, after the asphalt is fully mixed and stirred with several monomer structures and laid in the trough frame 4 and then flattened by a road compaction machine, during the flattening work, under the influence of pressure, a part of the outer ring of the disc 10 is embedded in the asphalt. The disc 10 plays a role in connecting the asphalt, thereby improving the connection stability between the asphalt and the disc 10. And the movable rod 9 is located inside the channel 8, which can prevent the asphalt from completely blocking the channel 8. Cooperating with the blocking effect of the disc 10, it further prevents the asphalt from entering the channel 8 and causing blockage. The asphalt layer 1 on the road surface is mixed and laid with the monomer structures. The characteristics of the asphalt make there be a certain interfacial relationship between it and water. The water can flow smoothly along the contact interface between the asphalt and the monomer structures and then is more easily infiltrated into the outer sphere 6 of the monomer structure, making the water on the road surface more easily infiltrated into the outer sphere 6 of the monomer structure. In this process, through the notch 11 opened on the disc 10, part of the water will flow downward through the notch 11 to improve the drainage efficiency. At the same time, during the use of the road, the driving of vehicles will generate a certain pressure on the road surface, and this pressure will be transmitted to the monomer structure. When there is water on the road surface, under the action of the pressure difference, the water will tend to move towards the outer sphere 6 with lower pressure, further increasing the drainage speed. Not only that, since the movable rod 9 and the channel 8 are not relatively fixed but can move in the channel 8, when the vehicle passes over the mixed layer of asphalt and several monomer structures inside the trough frame 4, the vibration and pressure of the vehicle will cause the movable rod 9 to move or vibrate slightly inside the channel 8. This is because the asphalt has a certain fluidity, so when the asphalt is mixed with the monomer structures, it does not have a high hardness like cement, and thus the asphalt cannot completely limit the absolute fixation of the movable rod 9 and the channel 8. On this basis, if there is a blockage in the channel 8, the problem of blockage can be reduced by the slight movement or vibration of the movable rod 9 inside the channel 8.Inside the outer sphere 6 of the monomer structure, several channels 8 are designed, which provide a dedicated path for the discharge of moisture. When moisture enters the outer sphere 6, it follows these channels 8, successively passing through the groove frame 4, the well frame 3, the grille 5, and is smoothly discharged through the sewer, ensuring the high efficiency of road surface drainage and effectively avoiding the adverse effects of road surface water accumulation on traffic and the road surface structure. During maintenance, only by removing the groove frame 4 from the well frame 3 through the lifting lug 12 can the maintenance operation be carried out, which is convenient and fast.

[0029] Finally, it should be noted that when the monomer structure is mixed with the asphalt layer 1, the outer sides of each movable rod 9 are covered with asphalt particles and are distributed in a circular form, enabling the asphalt to be in close contact with each other. The monomer structure and the asphalt layer 1 can be mixed with a small amount of asphalt binding glue. In the high-temperature state, the asphalt binding glue is similar to a liquid and solidifies at low temperature. After solidification, the asphalt binding glue bonds the asphalt particles and the monomer structure together, and then the asphalt layer 1 can form a stable structure. Even when subjected to external pressures such as those from pedestrians or vehicles, the monomer structure will not be damaged because the asphalt mainly plays a supporting role and does not rely entirely on the monomer structure for support. Moreover, the outer sphere 6 of the monomer structure has a high structural strength and will not be damaged. Even if the movable rod 9 bends, it does not affect the drainage effect. The monomer structure and the asphalt layer 1 can be mixed with a small amount of asphalt binding glue. After the asphalt binding glue solidifies, it bonds the asphalt particles and the monomer structure together. At this time, since there are gaps between the asphalt particles, water will flow along these gaps. When the asphalt particles are subjected to external pressure, the disc 10 will be embedded in the contact part with the asphalt particles. On the one hand, it improves the stability of the connection between the disc 10 and the asphalt particles. On the other hand, the disc 10 supports the asphalt and separates the asphalt particles to increase the gap between the asphalt particles. The notch 11 opened inside the disc 10 is like the mesh holes of a filter, allowing water to pass through while blocking impurities, thus achieving the purpose of filtration. Before use, the asphalt particles are first screened to ensure that the particle sizes are uniform, making it easier for the particles to be evenly distributed during the mixing process. When mixing, a mixing device such as a powerful mixer is selected. This type of device usually has a high mixing speed and a large mixing force, enabling the asphalt particles and the monomer structure to be fully mixed in a short time. After mixing, the asphalt particles surround the outer side of the outer sphere 6. After several asphalt particles are mixed with the monomer structure, they will ultimately form a structure that wraps the monomer structure, and the asphalt particles can come into contact with the asphalt particles connected to other monomer structures. The interaction between the asphalt will form a stable structure.
