Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically to prefabricated road drainage ditch structures. Background Technology

[0002] Road drainage ditches are facilities used in road engineering to collect and discharge surface water. Their main function is to prevent water accumulation from affecting the road structure and safety of use. They are usually arranged along the sides or central median of the road, such as curbside ditches and slope drainage ditches, to quickly drain rainwater, snowmelt, or water from the road surface and prevent water infiltration from damaging the roadbed or causing traffic accidents.

[0003] Currently, most drainage ditches are constructed by casting concrete on-site or by assembling precast components on-site. The former, with its cast-in-place construction, often results in drainage ditches with U-shaped, V-shaped, or trapezoidal cross-sections, which is time-consuming, makes it difficult to control on-site quality, and allows debris such as leaves to easily enter the drainage ditches, causing blockages in subsequent pipe networks. While the latter improves on-site laying efficiency through prefabrication, the drying process of grouting between individual precast components still affects construction efficiency. In addition, both methods rely on the overall inclination angle of the drainage ditch to guide water flow using gravity, but this method has limited drainage efficiency and affects overall drainage effectiveness. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated road drainage ditch structure to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The prefabricated road drainage ditch structure provided by this utility model includes a single ditch unit. The ditch unit has a flow channel inside. The cross-section of the flow channel is an inverted isosceles trapezoid. Both sides of the flow channel are provided with guide components. A collection filter screen is detachably installed at one end of the flow channel. A filter plate and a cover plate are sequentially installed on the top of the ditch unit. Flexible connectors that adapt to each other are provided at both ends of the ditch unit.

[0007] Preferably, the upper two sides of the flow channel are provided with fitting grooves, and both ends of the filter plate are fixedly connected with mounting plates that are adapted to the bottom of the fitting grooves. The cross-section of the filter plate is an inverted isosceles trapezoid.

[0008] Preferably, both ends of the bottom surface of the two mounting plates are fixedly connected with insert rods, and both ends of the two fitting grooves are provided with slots that are adapted to the insertion of the insert rods.

[0009] Preferably, the bottom of the filter plate is provided with several narrow strips, and several drainage grooves are provided on the two inclined surfaces of the filter plate. The bottom of each drainage groove faces the direction of water flow in the ditch, and each drainage groove is provided with a filter screen.

[0010] Preferably, the inner bottom of the filter plate is fixedly connected to two pull rings, and one end of the filter plate is fixedly connected to a baffle that matches its cross-sectional size, with a water leakage hole through the lower end of the baffle.

[0011] Preferably, the flow guide includes several flow guide plates fixedly connected to the inclined surfaces on both sides of the flow channel, and the bottom of the flow guide plates on both sides faces the direction of water drainage flow.

[0012] Preferably, the bottom of the side wall of the collecting filter is fixedly connected to two ear plates, and one end of the bottom surface of the flow channel is fixedly connected to two bolts. Both ear plates are provided with through holes that fit with the bolts. The bolts are threaded with nuts. The bottom of the collecting filter is adapted to the size of the bottom cross section of the flow channel and is provided with a sealing strip that abuts against it.

[0013] Preferably, the cover plate has several drainage grooves through it, and when the cover plate is installed in the fitting groove, its surface is flush with the upper surface of the water ditch unit. The bottom four corners of the water ditch unit are all fixedly connected with pointed support feet.

[0014] Preferably, the flexible connector includes a rubber pad fixedly connected to one end of the water ditch unit.

[0015] Preferably, each side wall of the connecting strip has a through hole, and each of the through holes has a bolt 2 inserted into it. Each side wall of the mating groove has a bolt hole for threaded connection with the bolt 2.

[0016] The beneficial effects are:

[0017] By placing multiple individual drainage ditch units sequentially into the excavated trench, adjusting the docking angle of another drainage ditch unit, and placing the docking groove below the connecting strip, the two are assembled and connected. During drainage, the water flows through the drainage channel and falls onto the filter plate. Small debris gathers at the bottom of the filter plate under the influence of gravity. The water flows down through several drainage ramps onto the slope of the flow channel. The gravity of the guide plate accelerates the flow into the water at the bottom of the flow channel, increasing the drainage speed. The laying process is quick and convenient, and it can be laid adaptably according to the undulation or curvature of the road surface. At the same time, it can collect debris and accelerate the drainage speed, improving the drainage effect. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-5As shown, this utility model provides a prefabricated road drainage ditch structure, including a ditch unit 1. The interior of the ditch unit 1 is provided with a flow channel 2. The cross-section of the flow channel 2 is an inverted isosceles trapezoidal design, and both sides of the flow channel 2 are provided with flow guides. A collection filter screen 6 is detachably installed at one end of the flow channel 2. A filter plate 3 and a cover plate 4 are sequentially covered on the top of the ditch unit 1. Flexible connectors 5 that are compatible with each other are provided at both ends of the ditch unit 1.

[0028] Reference Figure 3-4 As shown, the upper ends of the flow channel 2 are provided with fitting grooves 8 on both sides. The two ends of the filter plate 3 are fixedly connected with mounting plates 9 that are adapted to the bottom of the fitting grooves 8. The cross-section of the filter plate 3 is an inverted isosceles trapezoid. The bottom ends of the two mounting plates 9 are fixedly connected with insert rods 10. The two ends of the fitting grooves 8 are provided with slots 11 that are adapted to the insertion of the insert rods 10. When the filter plate 3 is installed on the two fitting grooves 8, the insert rods 10 can be inserted into the slots 11 to limit the shaking and displacement of the filter plate 3. The inverted isosceles trapezoidal design allows debris falling into the filter plate 3 to fall down the slope. At the same time, the water flows down into the flow channel 2 through the leakage chute 13. The fitting grooves 8 are convenient for placing the filter plate 3 with mounting plates 9 and the cover plate 4, making them more stable after installation.

[0029] Reference Figure 4 As shown, the bottom of the filter plate 3 has several narrow strips 14, and the two inclined surfaces of the filter plate 3 have several drainage grooves 13. The bottom of each drainage groove 13 faces the direction of water flow in the ditch, and each drainage groove 13 is equipped with a filter screen. The inner bottom of the filter plate 3 is fixedly connected to two pull rings 17. One end of the filter plate 3 is fixedly connected to a baffle 15 that matches its cross-sectional size, and the lower end of the baffle 15 has a drainage hole. Water entering the filter plate 3 through the drainage grooves 12 flows through the inclined surfaces of the filter plate 3. Small debris is filtered by gravity. The water flows down to the bottom of the filter plate 3 and then through several drainage channels 13 to the inclined surface of the flow channel 2. The drainage channels 13 can increase the contact range with the incoming water flow. The filter screen inside can intercept small pieces of debris. The water attached to the debris on the surface of the filter plate 3 can fall into the flow channel 2 through the strip slit 14. At the same time, the baffle 15 can intercept the debris on the surface of the filter plate 3, preventing the debris from flowing on the surface of the filter plate 3 with the water flow. Meanwhile, the drainage holes can allow the water stored on the surface of the filter plate 3 to fall. The pull ring 17 makes it easy to lift the filter plate 3 to clean the debris.

[0030] Furthermore, the guide component includes several guide plates 7 fixedly connected to the inclined surfaces on both sides of the flow channel 2, and the bottom of both guide plates 7 faces the direction of water drainage flow. The water flows down through several leakage channels 13 onto the inclined surface of the flow channel 2, and is accelerated by the gravity of the guide plates 7 into the water flow at the bottom of the flow channel 2, thereby increasing the drainage flow rate in the flow channel 2.

[0031] Reference Figure 3 As shown, two ear plates 602 are fixedly connected to the bottom side wall of the collecting filter 6, and two bolts 601 are fixedly connected to one end of the bottom surface of the flow channel 2. Both ear plates 602 are provided with through holes 603 that fit into the bolts 601. Nuts 604 are threaded onto the bolts 601. The bottom of the collecting filter 6 is adapted to the size of the bottom cross section of the flow channel 2 and is provided with a sealing strip that abuts against it. The collecting filter 6 can be installed in the flow channel 2 by fitting the ear plates 602 onto the bolts 601 and then rotating the nuts 604 on the bolts 601 to fix the collecting filter 6. The position of the collecting filter 6 can be selected in a position that is convenient for cleaning debris. At the same time, one or more collecting filters 6 can be set as needed.

[0032] Specifically, the cover plate 4 has several drainage grooves 12 through it, and when the cover plate 4 is installed in the fitting groove 8, its surface is flush with the upper surface of the ditch unit 1. The bottom of the ditch unit 1 is fixedly connected with pointed support feet 16 at the four corners. The drainage grooves 12 allow the road surface water to enter the flow channel 2, while blocking and intercepting large debris. The flush setting of the cover plate 4 can ensure the flatness of the road surface and avoid affecting the passage of vehicles. The pointed support feet 16 can make the ditch unit 1 effectively fit into the soil layer when it is placed into the excavated ditch, improve the grip and prevent displacement.

[0033] Reference Figure 2 As shown, the flexible connector 5 includes a rubber pad 501 fixedly connected to one end of the water ditch unit 1. The shape of the rubber pad 501 is adapted to the bottom of the cross-section of the flow channel 2. A connecting strip 502 is fixedly connected to the end of the rubber pad 501. A mating groove 503 adapted to the connecting strip 502 is opened at the other end of the water ditch unit 1. A sealing gasket is provided on the bottom surface of the connecting strip 502. Insertion holes 504 are opened through each side wall of the connecting strip 502 in each direction. A bolt 505 is inserted into each insertion hole 504. Each side wall of the mating groove 503 is provided with... The device is provided with a bolt hole 506 for threaded connection with bolt 505. By adjusting the mating angle of another drainage unit 1 and placing the mating groove 503 below the connecting strip 502, the insertion hole 504 is aligned with the bolt hole 506. Bolt 505 is then inserted into both insertion hole 504 and bolt hole 506 and rotated to complete the assembly connection between the two drainage units 1. The design of the rubber pad 501 allows the next drainage unit 1 to be adaptively adjusted according to the curvature or downward slope of the drainage ditch, and effectively ensures the water-proof effect at the connection between the two drainage units 1.

[0034] The working principle of this utility model:

[0035] During installation, multiple drainage ditch units 1 are placed sequentially in the dug trench, with the four pointed support legs 16 driven into the ground, ensuring the bottom ends of several guide plates 7 face the direction of drainage flow. The docking angle of another drainage ditch unit 1 is then adjusted, and the docking groove 503 is placed below the connecting strip 502, aligning the insertion hole 504 with the bolt hole 506. Bolts 505 are simultaneously inserted into both insertion holes 504 and bolt holes 506 and rotated to complete the assembly connection between the two drainage ditch units 1. The collecting filter 6 is then installed at the end of the drainage ditch unit 1 in a suitable position. Finally, a filter plate 3 and a cover plate 4 are sequentially added above the drainage ditch unit 1 to ensure proper connection. Plate 9 and cover plate 4 are placed in the fitting groove 8. The bottom end of the water leakage groove 13 on the filter plate 3 also faces the direction of drainage flow. When the water ditch drains water, it falls from the water leakage groove 12 on the cover plate 4 onto the surface of the filter plate 3. At this time, large pieces of debris are isolated on the surface of the cover plate 4. The water flow then passes through the inclined surfaces on both sides of the filter plate 3. Small pieces of debris gather at the bottom of the filter plate 3 under the influence of gravity. The water flow falls through several water leakage grooves 13 onto the inclined surface of the flow channel 2. It is accelerated by the gravity of the guide plate 7 and flows into the water flow at the bottom of the flow channel 2, increasing the drainage flow rate. The debris that leaks into the flow channel 2 is blocked and intercepted by the collection filter screen 6.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
