Background Art

[0002] As people's understanding and requirements for the living environment become higher and higher, the landscape of urban parks and walking trails has attracted much attention. In the landscape composition of the park, the trestle plays an indispensable role. The trestle is not only a transportation medium for connecting trails and getting close to nature, but also a part of the landscape itself. When the road section conditions are limited, the construction of the ditch bridge can greatly improve the quality of the pedestrian road.

[0003] Traditional cover ditch structure: a cover is laid directly above the intercepting ditch, and water holes are set on the cover. The slope water flows through the holes in the cover to the intercepting ditch below. The traditional cover ditch structure is easy to cause shaking when walking, and the slope water flows directly into the intercepting ditch through the holes on the cover surface. The flow cross-section is small, the water collection capacity is poor, and the walking experience is poor.
