Description

Technical Field

[0001] The utility model relates to the technical field of bridge green belt drainage, in particular to a municipal bridge green belt drainage structure. Background Art

[0002] With the high-quality development of cities, the requirements for landscape greening of urban bridges are gradually increasing. Green belts, sidewalks, non-motorized vehicle lanes and motor vehicle lanes are usually set up in newly built secondary trunk roads and branch roads in cities. However, in the actual municipal bridge projects, there are usually no green belts on the bridges, so the green belts of the roadbed section end at both ends of the bridge head. In order to keep the green belt of the entire road uninterrupted and meet the landscape greening effect, the bridge section also needs to retain the green belt. When there is no green belt on the bridge section, the rainwater from the sidewalk and non-motorized vehicle lane can directly flow horizontally to the motor vehicle lane and then be discharged through the main beam drainage pipe. Now a green belt is set up on the bridge, which separates the pedestrian and non-motorized vehicle lanes from the motor vehicle lanes. The rainwater in the range of the pedestrian and non-motorized vehicle lanes flows directly horizontally into the green belt. With the development of urban construction, the width of the sidewalk and non-motorized vehicle lane is widened, the catchment area is larger, and the amount of rainwater flowing into the green belt is gradually increasing, resulting in the gradual prominence of the drainage problem of the green belt. Utility Model Content

[0003] In view of this, a municipal bridge green belt drainage structure with smooth drainage and independent drainage is provided.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a municipal bridge green belt drainage structure, which is used to solve the drainage problem of the green belt and the pedestrian and non-motorized vehicle sidewalk on the municipal bridge. The municipal bridge green belt drainage structure is arranged in the enclosed area of ​​the main beam system, the pedestrian and non-motorized vehicle sidewalk system and the motor vehicle sidewalk system, including a green belt drainage structure system. The green belt drainage structure system is sequentially arranged from top to bottom with a cultivated soil layer, a first water-filtration geotextile, a crushed stone layer, a second water-filtration geotextile and a green belt drainage pipe. The green belt drainage pipe is arranged at the lowest point of the green belt in the vertical direction along the main beam system, and is used to drain the green belt and the accumulated water that flows horizontally into the green belt from the pedestrian and non-motorized vehicle sidewalk.

[0005] Furthermore, the green belt drainage structure system also includes a waterproof cement mortar layer, the pedestrian and non-motorized vehicle sidewalk system includes sidewalk piers, the main beam system includes a cast-in-place layer, and the motor vehicle sidewalk system includes an anti-collision guardrail. The waterproof cement mortar layer is laid along the inner wall surface of the sidewalk piers, the upper surface of the cast-in-place layer and the inner wall surface of the anti-collision guardrail to form a drainage ditch.

[0006] Furthermore, the heights of the two side surfaces of the waterproof cement mortar layer are at least higher than the upper surface of the cultivated soil layer.

[0007] Furthermore, the main beam system also includes a main beam drainage pipe, and the accumulated water in the motor vehicle lane system is discharged from the main beam drainage pipe. The green belt drainage pipe and the main beam drainage pipe are independent of each other and are not connected to each other.

[0008] Furthermore, the green belt drainage pipe is arranged vertically.

[0009] Furthermore, the first water-filtration geotextile completely covers the surface of the gravel layer, and the second water-filtration geotextile completely covers the top of the green belt drainage pipe.

[0010] Furthermore, the cultivated soil layer is used for planting the green belt, and the cultivated soil layer is laid uninterruptedly along the vertical direction of the main beam system.

[0011] Furthermore, the pedestrian and non-motor vehicle sidewalk includes a pedestrian sidewalk and a non-motor vehicle sidewalk.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects: First, the drainage ditch is formed by a waterproof cement mortar layer, and the green belt drainage pipe is set below the lowest point of the green belt. The accumulated water on the pedestrian and non-motor vehicle sidewalk flows into the green belt area and converges along the drainage ditch to the green belt drainage pipe for discharge, solving the drainage problem of the bridge green belt. Second, the green belt drainage pipe and the main beam drainage pipe are independent of each other and are not connected to each other, so that the drainage of the bridge green belt will not be affected by fallen leaves, rotten soil and garbage on the motor vehicle sidewalk.
