Abstract
Description
Technical Field
[0001] This utility model relates to the field of road drainage technology, and in particular to a roadbed drainage structure. Background Technology
[0002] The roadbed structure refers to the layered structure of the entire road. A road is composed of a roadbed layer and different pavement building stones laid in layers. The roadbed structure of roads built in different sections and regions is different. Among them, the roadbed structure of municipal roads has higher requirements because municipal roads are located in urban areas with high vehicle and pedestrian traffic and many buildings. The load transmitted from the road surface to the entire road is large. At the same time, it is also necessary to ensure the drainage of the road surface to avoid flooding during rainy days. If the road surface is not drained well, the road will be flooded. If water seeps into the roadbed layer, it will damage the stability of the road. The drainage of the road reflects the level of the overall planning and design of municipal roads, and ensuring smooth drainage of urban roads is becoming increasingly important.
[0003] In existing technologies, to avoid clogging the drainage system, filters are typically installed at the drain grate. In areas with a lot of debris, multiple layers of filters may even be installed. However, an excessive number of filters can easily cause clogging and make it difficult to remove filtered debris from inside the drain. This affects the efficiency of drainage and sewage flow. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a roadbed drainage structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A roadbed drainage structure includes a road surface and a roadbed. A drainage trough is provided on the roadbed, and drainage grates corresponding to the drainage trough are embedded in the road surface. Drainage pipes are buried in the roadbed on both sides of the drainage trough, with one end of each pipe connected to the middle of the drainage trough and communicating with it. An anti-clogging component is provided in the drainage trough. The anti-clogging component includes a filter screen, a sand collection tray, and a drainage cylinder mesh. The drainage cylinder mesh is correspondingly arranged with the drainage pipes, and both ends of the drainage cylinder mesh are connected through the middle of the filter screen. The lower side of the filter screen is detachably connected to the sand collection tray, and a sedimentation mesh is provided on the upper side of the sand collection tray.
[0006] Preferably, the drainage grate is detachably connected to the road surface, the top of the filter screen is detachably connected to the bottom of the drainage grate, and the filter screen is suspended in the drainage channel.
[0007] Preferably, the upper part of the filter screen is provided with a constricted neck and an flared opening, and the flared opening of the filter screen is provided corresponding to the drain hole of the drain grate.
[0008] Preferably, at least one set of drain pipes is provided on the side of the drainage trough, and a drainage gap of 2 to 10 cm is provided between the drain pipe port and the filter screen cover; the drain screen port and the drain pipe port are located at the same height and close to each other, and the diameter of the drain screen is larger than the diameter of the drain pipe.
[0009] Preferably, the sand accumulation tray and the sedimentation net are detachably connected, and the sedimentation net is arranged in a wavy, bent manner.
[0010] Preferably, the sedimentation mesh and drainage cylinder mesh are fine filter meshes, and the filter screen is a coarse filter mesh.
[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has an anti-clogging component installed below the drainage grate, and the filter screen cover has a cage-like structure, which is easy to remove and clean. At the same time, it increases the side and top filter surfaces to intercept and collect large debris such as branches and leaves. With the help of gravity and sewage flushing, the accumulated debris is easily dropped, preventing branches and leaves from completely clogging the filter screen and ensuring stable drainage. Smaller debris and silt are gathered and deposited through the sedimentation net and sand collection tray. In addition, a drainage cylinder net is installed to ensure the sewage flow efficiency between the drainage pipes in the drainage system. Attached Figure Description

[0014] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0015] Reference Figure 1-4 A roadbed drainage structure includes a road surface 1 and a roadbed 2. A drainage trough 41 is provided on the roadbed 2, and a drainage grate 4 corresponding to the drainage trough 41 is embedded on the road surface 1. The drainage grate 4 is detachably connected to the road surface 1 to facilitate regular cleaning of the drainage trough 41 for blockage. Drainage pipes 3 are buried in the roadbed 2 on both sides of the drainage trough 41 for drainage transportation into rivers or underground drainage systems. At least one set of drainage pipes 3 is provided on the side of the drainage trough 41 to form a roadbed drainage system. One end of the drainage pipe 3 is connected to the middle of the drainage trough 41 and they are interconnected. Sewage is discharged from the middle of the drainage trough 41 to ensure drainage efficiency. Bottom drainage can cause sewage and sediment to settle, which can easily clog the pipes. If the drainage position is too high, it can easily lead to excessive water accumulation and the breeding of mosquitoes and bacteria. The drainage ditch 41 is equipped with an anti-clogging component 5, which is used to filter, intercept and store the mud, sand and branches that accumulate during the drainage process for a short period of time, while ensuring smooth drainage, avoiding water accumulation on the road, preventing garbage from clogging the drain, and ensuring the long-term drainage effect of the drainage ditch 41. The anti-clogging component 5 includes a filter screen 51, a sand collection tray 52, and a drainage screen 54. The top of the filter screen 51 is detachably connected to the bottom of the drainage grate 4 via clips or screws, facilitating disassembly and cleaning. The filter screen 51 has a cage-like structure, increasing the side and top filtration surfaces to intercept and collect large debris such as branches and leaves. Utilizing gravity and wastewater flushing, accumulated debris easily falls off and does not remain attached to the filter screen, effectively preventing branches and leaves from completely clogging it and ensuring reliable drainage. The filter screen 51 is suspended within the drainage trough 41, allowing wastewater to flow around it. The amount of debris and cleaning frequency within the area can be adjusted by changing the size of the drainage trough 41 and the filter screen 51 to accommodate the drainage and impurities brought in during the drainage process, ensuring sufficient filtration area. The filter screen 51 has a constricted neck and an flared opening at the top to increase the filtration area. The complex structure at the constricted neck effectively prevents branches and leaves from sticking together and completely clogging the entire filter screen. The flared opening of the filter screen 51 is set to correspond to the drainage hole of the drainage grate 4. At the same time, it is combined with the drainage cylinder net 54 to filter and buffer the sewage flowing down from the drainage grate 4, reducing the impact energy of the fall and minimizing the stirring of the bottom silt. A drainage gap is provided between the drain pipe 3 port and the filter screen 51. The drainage gap is 2 to 10 cm, and 5 cm is generally selected to facilitate water flow and allow water outside the filter screen 51 to enter the drain pipe 3 through the drainage gap. The drainage cylinder 54 is open at both ends and is located in the middle of the filter screen 51. The drainage cylinder 54 is correspondingly set with the drainage pipe 3. The port of the drainage cylinder 54 and the port of the drainage pipe 3 are at the same height and close to each other. The diameter of the drainage cylinder 54 is larger than the diameter of the drainage pipe 3, which facilitates the flow of sewage between the drainage pipes 3 and avoids the filter screen 51 from being blocked, thus affecting the efficiency of sewage flow. The filter screen 51 is detachably connected to the sand collection tray 52 on the lower side. The sand collection tray 52 is provided with a sedimentation net 53 on the upper side to reduce water sloshing and prevent mud and sand from being stirred up. The sand collection tray 52 and the sedimentation net 53 are detachably connected. The sedimentation net 53 is set in a wavy bend to facilitate the sedimentation and gathering of branches and leaves and impurities. The sedimentation net 53 and drainage cylinder net 54 are made of fine filter nets. The fine mesh reduces the impact of water flow and gathers sediment, sand and branches. The filter cover 51 is made of coarse filter net to reduce production costs.
[0016] In this embodiment, when it rains or is irrigated, water accumulates on the road surface and flows into the drainage trough 41 through the drainage grate 4. During the flow of sewage, mud, sand and branches fall down through the drainage holes of the drainage grate 4. The filter screen 51 intercepts and filters the sewage, which accumulates in the drainage trough 41 and is discharged through the drainage pipe 3. The wavy and bent structure of the drainage pipe 3 collects mud, sand and branches, reduces water fluctuations, and facilitates the sedimentation of mud in the sand collection tray 52 for easy subsequent cleaning. Multiple drainage channels 41 are connected by drainage pipes 3 to form a roadbed drainage system, which discharges road sewage into rivers or underground drainage systems. When water flows in drainage pipes 3, it passes through drainage channels 41 and flows directly through drainage nets 54, avoiding clogging of the filter screen and affecting drainage efficiency.
