[0002] Concrete roadbed drainage systems are essential drainage systems in road construction, typically installed on either side or in the center of the roadbed. Their primary function is to effectively collect and drain rainwater from the pavement and roadbed, preventing water accumulation and directing it to an appropriate drainage system. This reduces the risk of roadbed subsidence and cracking, maintains roadbed stability and safety, and extends the life of the road.

[0003] However, the existing drainage devices have the following disadvantages. Some drainage devices used on cement concrete roadbeds are usually composed of water pipes. Drainage is carried out by pre-burying the water pipes in the concrete foundation pit. However, the pre-buried depth of the water pipes is relatively shallow, the drainage efficiency is poor, and the water flow will impact the inner wall of the drainage device. After a long period of impact, the inner wall will be damaged, and the practicality is not high. Therefore, we proposed a U-shaped drainage device. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a U-shaped drainage device, including a drainage trough body 1 and steel bars 4, a water inlet 2 is opened on the top of the drainage trough body 1, side plates 3 are welded on both sides of the drainage trough body 1, and the steel bars 4 are welded to one side of the side plates 3.

[0023] In specific implementation, some drainage devices used on cement concrete roadbeds are usually composed of water pipes, and drainage is achieved by pre-burying the water pipes in the concrete foundation pit. However, the pre-buried depth of the water pipes is relatively shallow, the drainage efficiency is poor, and the existing drainage devices are easily damaged and have low practicality. The drainage trough body 1 can be installed in the concrete foundation pit, and the side panels 3 and steel bars 4 are supported on both sides of the drainage trough body 1 to improve the installation stability of the drainage trough body 1. The cross-sectional shape of the drainage trough body 1 is U-shaped, which can increase the drainage volume and improve the practicality of the drainage device.

[0024] See also Figure 1-Figure 5 , an inner lining groove 5 is provided on the inner side of the drainage trough main body 1, and docking plates 9 are welded on both sides of the lining groove 5. Sound-absorbing cotton 13 is provided in the inner cavity of the docking plate 9, and a docking block 8 is welded on one side of the docking plate 9. A second docking groove 7 and a first docking groove 6 are provided on the inner wall of the drainage trough main body 1 near the docking plate 9 and the docking block 8. The docking plate 9 is adapted to the size of the No. 2 docking groove 7, and the size of the No. 1 docking groove 6 is adapted to the size of the docking block 8. Limit bolts 10 are provided on both sides of the lining groove 5 near the docking plate 9, and threaded holes 11 are provided on the inner wall of the lining groove 5 near the limit bolts 10. Limiting holes 12 are provided on the inner walls of both sides of the drainage trough main body 1, and the cross-sectional shapes of the docking block 8 and the No. 1 docking groove 6 are both set to "T" shape, and the number of the limit bolts 10 is set to two.

[0025] When being implemented specifically, because the drainage volume is sometimes large, the water flow will impact the inner wall of the drainage device. After a long period of impact, the inner wall will be damaged. The entire drainage device needs to be replaced later, which is troublesome and the drainage device is not convenient to reuse. The wear resistance of the drainage device can be improved by the lining groove 5. By pushing the lining groove 5 into the drainage trough body 1, the lining groove 5 drives the docking plate 9 and the docking block 8 to slide into the second docking groove 7 and the first docking groove 6, and then inserting the limit bolt 10 into the threaded hole 11, so that the limit bolt 10 and the threaded hole 11 are threadedly engaged. Finally, one end of the limit bolt 10 is stuck in the limit hole 12, which can limit the lining groove 5, facilitate and quickly assemble the lining groove 5 to the drainage trough body 1, and facilitate subsequent disassembly. The drainage device can be reused, and the sound-absorbing cotton 13 in the docking plate 9 can absorb water flow noise, reduce noise pollution, improve the convenience of the drainage device and extend its service life.

[0026] Working principle: When using the U-shaped drainage device, first install the lining groove 5 into the inner wall of the drainage trough body 1 through the docking plate 9, the docking block 8 and the limit bolt 10, and then install the drainage trough body 1 into the concrete pavement foundation pit through the steel bar 4 and the side plate 3, and fix the drainage trough body 1 by pouring concrete. During drainage, water flows into the drainage trough body 1 from the water inlet 2, and the sound-absorbing cotton 13 absorbs the noise of the water flow, thereby improving the practicality and convenience of the drainage device. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.
