Description

Technical Field

[0001] This application relates to the technical field of bridge drainage, and in particular to a concealed drainage system for landscape suspension bridges. Background Technology

[0002] Modern tourist attractions increasingly demand novelty and uniqueness. To enhance visitors' travel experience and visual enjoyment, suspension bridges have become an essential facility for many tourist sites. Walking on a suspension bridge offers visitors a fresh and expansive view, allowing them to better appreciate the beauty of the scenery and enhancing their overall experience while also contributing to the development of the scenic area.

[0003] To further enhance the visitor experience and safety, flowers, trees, and shrubs are planted along the sides of the suspension bridge to blend in with the natural environment, and sunshades are installed on the bridge roof to block direct sunlight. However, in rainy weather, dealing with rainwater from the sunshades and the bridge surface becomes a challenge.

[0004] Traditional drainage methods involve guiding rainwater directly down the sides of the bridge. However, vegetation along the bridge can obstruct the flow, and rainwater from the sunshades can splash onto visitors, causing water accumulation in some areas and affecting their experience. While installing drainage pipes would provide timely drainage, their exposed nature would detract from the overall aesthetics of the suspension bridge, reducing its integration with the natural environment and negatively impacting the visitor experience.

[0024] This application discloses a concealed drainage system for a landscape suspension bridge 7. (Refer to...) Figure 1-3 This includes the canopy drainage pipe assembly 1, the bridge deck drainage pipe assembly 2, the flower bed drainage pipe assembly 3, and the pier drainage pipe assembly 4, which are located inside the suspension bridge 7 and are arranged from top to bottom. The top of the canopy drainage pipe assembly 1 is connected to a top drainage outlet 71 located at the lowest point of the canopy. A bridge pillar connects the canopy and the bridge deck, with the top drainage outlet 71 located at the top of the pillar. The canopy is lowest at the end closest to the pillar. The top of the bridge deck drainage pipe assembly 2 is connected to a bridge deck drainage outlet 72 located in the pedestrian walking area. The top of the flower bed drainage pipe assembly 3 is connected to a flower bed drainage outlet 73 located in the planting area. Multiple bridge deck drainage outlets 72 and flower bed drainage outlets 73 are spaced apart along the length of the suspension bridge 7. The bridge deck drainage outlet 72 is located on the side of the flower bed drainage outlet 73 closest to the canopy.

[0025] The bottoms of the canopy drainage pipe assembly 1, the bridge deck drainage outlet 72, and the flower bed drainage pipe assembly 3 are all connected to the top of the pier drainage pipe assembly 4, and the bottom of the pier drainage pipe assembly 4 is connected to the municipal drainage system. Rainwater from the canopy flows into the lowest top drainage outlet 71 to prevent splashing. Rainwater from the bridge deck flows into the bridge deck drainage outlet 72 to prevent water accumulation. Rainwater from the planted areas flows into the flower bed drainage outlet 73 to prevent water accumulation along the bridge edge. All rainwater collects at the pier drainage pipe assembly 4 and flows into the municipal drainage system, ensuring timely drainage. Furthermore, the canopy drainage pipe assembly 1, the bridge deck drainage outlet 72, the flower bed drainage pipe assembly 3, and the pier drainage pipe assembly 4 are all located inside the suspension bridge 7, thus not affecting the aesthetics of the suspension bridge 7.

[0026] Reference Figure 2 and 3 To ensure the overall aesthetics and balance of the suspension bridge 7, and to accommodate visitors coming from both directions, two sets of drainage pipes are symmetrically arranged around the bridge pillars, including the canopy drainage pipe group 1, the bridge deck drainage outlet 72, and the flower trough drainage pipe group 3. The bridge pillars are located at the center of the suspension bridge 7 and are arranged along the length of the suspension bridge 7 to support the entire canopy.

[0027] Reference Figures 1 to 3 The canopy drainage pipe assembly 1 includes a canopy top pipe 11, a canopy longitudinal water pipe 12, and a canopy vertical water pipe 13 located inside the bridge pier.

[0028] In this system, a baffle plate 5 is installed between two adjacent top drain outlets 71 of the same set of canopy drainage pipe groups 1. The baffle plate 5 is installed on the top of the canopy, and the baffle plates 5 of the two sets of canopy canopies are connected in a V-shape. Baffle plates 5 are installed at both ends of the canopy along the length of the suspension bridge 7 to collect rainwater and allow it to flow into the top drain outlet 71. The top drain outlets 71 of the two sets of canopy drainage pipe groups 1 are staggered along the length of the suspension bridge 7 to guide rainwater diversion and reduce rainwater accumulation. Therefore, there are two sets of top drain outlets 71 of canopy drainage pipe groups 1 between two adjacent baffle plates 5.

[0029] To quickly guide rainwater to the drainage system, cement mortar is laid around the flower bed drainage outlet 73 and a 1% cross slope is set. The bridge deck drainage outlet 72 is set with a 0.5% cross slope on the side of the bridge deck facing the canopy. The top surface of the bridge column near the center of the suspension bridge 7 at the top drainage outlet 71 is set with a 1% slope.

The longitudinal water pipe 32 of the flower bed is laid along the length of the suspension bridge 7. The flower bed top pipe 31 connects the flower bed drainage outlet 73 and the longitudinal water pipe 32 of the flower bed. Multiple flower bed downpipes 33 are arranged at intervals along the length of the suspension bridge 7. The flower bed downpipes 33 connect the longitudinal water pipe 32 of the flower bed and the bridge pier drainage pipe group 4.

[0035] Reference Figures 4 to 6 The pier drainage pipe assembly 4 includes an integrated jacking pipe 41, a pier vertical drainage pipe 42, and a municipal connection. The integrated jacking pipe 41 is located inside the suspension bridge 7 and includes a first integrated pipe 411 laid along the length of the suspension bridge 7 and a second integrated pipe 412 laid along the width of the suspension bridge 7. Among them, there are three first integrated pipes 411, which are connected to all the vertical water pipes 13 of the canopy, all the drainage pipes 23 of the bridge deck and all the drainage pipes 33 of the flower beds respectively. There are two second integrated pipes 412, which are located at both ends of the suspension bridge 7 along the length direction. One second integrated pipe 412 is connected to one end of the three first integrated pipes 411.

[0036] Both the first integrated pipe 411 and the second integrated pipe 412 are located inside the bridge body. In order to guide rainwater to flow down, the end of the second integrated pipe 412 near the canopy is inclined upward and the end near the pier is inclined downward.

[0037] Secondly, the vertical drainage pipe 42 of the pier is located inside the pier, and the top end of the vertical drainage pipe 42 of the pier is connected to the second integrated pipe 412 and the bottom end is connected to the municipal connection pipe 43.

[0038] In addition, for ease of maintenance, the municipal connection pipe 43 is equipped with multiple pipes that are connected to the municipal drainage system nearby. A maintenance valve 44 is connected to one side of the vertical drainage pipe 42 of the pier, and the maintenance valve 44 is located on the outside of the pier.

[0039] To ensure the service life of the drainage system, the canopy drainage pipe assembly 1, bridge deck drainage pipe assembly 2, flower trough drainage pipe assembly 3, and bridge pier drainage pipe assembly 4 are all made of stainless steel. Since there are three pipes connected together, a T-joint is used for connection to strengthen the connection.

[0040] The implementation principle of a concealed drainage system for a landscape suspension bridge 7 in this application embodiment is as follows: rainwater from the canopy flows into the lowest top drain outlet 71 to prevent splashing; rainwater on the bridge surface flows into the bridge surface drain outlet 72 to prevent water accumulation; rainwater from the planted areas flows into the flower bed drain outlet 73 to prevent water accumulation along the bridge edge; all rainwater collects at the pier drainage pipe assembly 4 and flows into the municipal drainage system to ensure timely drainage. Furthermore, the canopy drainage pipe assembly 1, bridge surface drain outlet 72, flower bed drainage pipe assembly 3, and pier drainage pipe assembly 4 are all located inside the suspension bridge 7, thus not affecting the aesthetics of the suspension bridge 7.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
