Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a flexible drainage universal joint and a flexible drainage system. Background Art

[0002] A viaduct is a bridge that crosses roads in urban construction. The multi-layer three-dimensional structure of the viaduct ensures the smooth flow of urban traffic. However, there are many problems with the bridge deck drainage system, which has affected traffic and safety. First of all, the drainage holes on the bridge deck are mostly arranged intermittently, which cannot quickly drain the accumulated water. At the same time, the drainage holes are small and easily blocked by debris. When the instantaneous rainfall is too large, rainwater is easily accumulated on the road surface. The tires of vehicles traveling at high speeds are easily affected by the accumulated water and easily slip out of control. The splashing water will affect the passage of vehicles and pedestrians on the lower layer. In addition, the drainage holes cannot be effectively guaranteed to be in a low position during the pavement paving process, resulting in accumulated water and puddles on some sections of the road. There is also no way to drain the interlayer water. The existing drainage system can only drain the road surface, but cannot handle the water that penetrates into the asphalt concrete pavement layer, resulting in backflow problems at the expansion joints or wet joints. The accumulated water on the bridge surface will corrode the expansion joints, reduce the strength of the concrete, and shorten the service life of the bridge. The accumulated water seeps from the bridge to the bottom of the bridge, spreads along the bridge deck, and flows to the cap, which is easy to cause rust on the bearings, affecting the performance of the bearings. At the same time, due to the dark space under the bridge, water stains will appear on the wall for a long time after the seepage, breeding moss and turning black, affecting the durability of the concrete structure, affecting the appearance of the bridge deck, and affecting the performance of other components.

[0003] Traditional drainage systems cannot effectively solve the above problems. A Chinese invention patent application with publication number CN117822429A discloses a flexible drainage unit, a flexible drainage system and a flexible drainage system combination method. The flexible drainage unit includes a gate-type drainage board, which is provided with multiple drainage holes on the top and both sides; multiple longitudinal support ribs are installed on the top and both sides of the gate-type drainage board, and are arranged along the extension direction of the gate-type drainage board; the cross-section of the transverse support rib is a gate-shaped structure, which is fixedly arranged on the inner wall of the gate-type drainage board. Multiple flexible drainage units are arranged in parallel, and two adjacent flexible drainage units are connected end to end in sequence to form a flexible drainage system. After being arranged along the entire road surface, it is conducive to the discharge of road surface water and interlayer water, and improves the existing road surface water problem and interlayer water backflow problem. However, the flexible drainage system mainly utilizes the flexibility of the materials of the gate-type drainage board, the longitudinal support ribs and the transverse support ribs themselves, and the deformation capacity is relatively limited, and it cannot adapt well to sudden ups and downs or turns of the road surface.
