Description

Technical Field

[0001] The utility model belongs to the technical field of bridge deck drainage, and in particular relates to an ecological bridge drainage structure with multiple functions. Background Art

[0002] As environmental and landscape requirements continue to rise, ecological bridge drainage systems are becoming increasingly important in modern bridge design. These systems must not only effectively address drainage and water seepage issues in planted areas, but also consider environmental protection and landscape harmony. However, traditional ecological bridge drainage systems suffer from the following major issues.

[0003] First, traditional ecological drainage facilities are usually arranged on the inner side of the railing, connected to the longitudinal drainage pipe through the vertical downpipe, and finally connected to the municipal drainage system. Although this arrangement can achieve basic drainage functions, it often ignores the impact on the overall aesthetics of the bridge and the environmental coordination. In particular, the longitudinal drainage pipe is generally exposed on the outside of the structure and connected to the main structure of the bridge through fasteners such as buckles, which not only affects the aesthetics of the bridge, but also is not conducive to the durability maintenance of the pipeline. Secondly, due to the influence of debris such as soil, sediment, branches and leaves in the planting area, traditional drainage facilities are prone to blockage. After blockage, the drainage pipe is difficult to unclog and the workload is large, which increases maintenance costs and safety hazards. Chinese patent CN118186901A discloses a side drainage structure for a concrete bridge. The invention reduces the deadweight of the structure by adopting a lighter steel structure wind nozzle consistent with the cross-section of the main bridge, and solves the problem that conventional PVC pipes are difficult to unclog. However, the drainage structure has a single function and lacks an operating interface, which can easily cause people and equipment to fall, and has poor safety.

[0004] Therefore, it is necessary to adopt a multifunctional ecological drainage structure to solve the shortcomings of traditional drainage facilities in terms of functionality, safety and aesthetics. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the above-mentioned existing technologies and provide a multifunctional ecological bridge drainage structure, which combines the functions of drainage, post-maintenance work platform, protection against falling objects on the bridge deck and bridge wind nozzle, and beautifies the overall shape of the bridge.

It should be noted that the "inside" and "outside" of "high inside and low outside" are divided by the bridge railing, and the end of the transverse drainage pipe located on the inside of the railing is higher than the end located on the outside of the railing.

[0018] Furthermore, the drainage system and the air nozzle also include a keel and an outer covering plate, and the outer covering plate covers the outside of one end of the transverse drainage pipe connected to the grille cover plate and the outside of the air nozzle.

[0036] Example 1

[0037] See Figure 1 and Figure 2 , the utility model provides a multifunctional ecological bridge drainage structure, including a drainage system and a wind nozzle;

[0038] The drainage system includes a filter layer 110, a transverse drainage pipe 130, a grille cover 160, and a longitudinal drainage groove 180;

[0039] The filter layer 110 is arranged on the inner side of the railing 2, between the planting area 3 and the ground cover 120. The planting area 3 and the filter layer 110 are both arranged horizontally on the bridge deck pavement 4 and at the same height. The ground cover 120 and the bridge deck pavement 4 are both arranged horizontally on the bridge deck and connected.

[0040] The grille cover 160 and the longitudinal drainage groove 180 are both arranged on the outside of the railing 2;

[0041] One end of the transverse drainage pipe 130 is connected to the filter layer 110, and the other end passes through the floor mat 120 and is connected to the grille cover 160. The grille cover 160 is detachably covered on the upper end of the longitudinal drainage groove 180.

[0042] The horizontal slope of the wind nozzle is lower than the bridge deck. A side baffle 190 is provided at one end of the horizontal slope of the wind nozzle away from the bridge to collect rainwater outside the railing 2 and form a space to prevent falling objects.

[0043] The longitudinal drainage groove 180 is fixedly installed inside the opening of the air nozzle, and the grille cover 160 is located at the same horizontal plane as the horizontal slope of the air nozzle.

[0044] In this embodiment, the filter layer 110 is a non-woven fabric wrapped with pebbles, which is used to filter soil, mud, branches and leaves and other debris in the planting area 3 to prevent the drainage pipe from being blocked.

[0045] In this embodiment, the transverse drain pipe 130, the grille cover 160, and the longitudinal drain pipe 180 are made of PVC, and the cross-sectional shape of the transverse drain pipe 130 is circular, wherein the end of the transverse drain pipe 130 located on the inner side of the railing 2 is higher than the end located on the outer side of the railing 2, and the transverse slope of the transverse drain pipe 130 is not less than 2%.

[0046] Specifically, the drainage system and wind nozzle also include a keel 140 and an outer panel 150. The outer panel 150 covers the outside of one end of the horizontal drainage pipe 130 connected to the grille cover 160 and covers the outside of the wind nozzle. This hidden drainage system makes the bridge landscape effect better.

[0047] In this embodiment, the outer covering plate 150 is an aluminum plate, which can reduce the deadweight of the bridge.

[0048] Specifically, a plurality of drainage trough bases 170 are installed at the bottom end of the longitudinal drainage trough 180 for fixing and supporting the longitudinal drainage trough 180 ; the drainage trough base 170 is fixedly connected to the keel 140 in the vertical direction for fixing and supporting the drainage trough base 170 .

[0050] The specific working process of the drainage structure in this embodiment is as follows:

[0051] The drainage system connects to the planting area 3 and is arranged continuously along both sides of the bridge deck. After rainfall or irrigation, water accumulated in the planting area 3 and on the bridge deck first passes through the filter layer 110 to remove soil, silt, and other debris. It then enters the transverse drainage pipe 130 and the longitudinal drainage trough 180 covered with a grille cover 160. The longitudinal drainage trough 180 also collects water on the slope across the wind nozzle, and finally enters the municipal drainage system. When the drainage system needs maintenance, staff can perform the operation directly on the slope across the wind nozzle. The removable grille cover 160 ensures that the drainage system is easy to inspect and repair, and convenient for maintenance and dredging.

[0052] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art.
