Description

Technical Field

[0001] This utility model relates to the field of bridge technology, and to an ecological bridge, and more particularly to an ecological bridge with controllable height based on a truss structure. Background Technology

[0002] In recent years, with the increasing demands for urban landscapes and ecological environments, some ecological bridges integrating pedestrian walkways and pathways for animals and plants have emerged both domestically and internationally. Ecological bridges not only meet pedestrian needs but also provide habitats and migration routes for surrounding flora and fauna. Conventional ecological bridge structures primarily utilize beam bridges, with the bridge surface covered with soil or planted with green boxes, mainly planted with herbaceous plants and shrubs; some ecological bridges also include small trees.

[0003] Conventional ecological bridges are primarily beam bridges. As the span increases, the bridge structure height increases rapidly, making it difficult to control the height of the substructure. Furthermore, the growth height of trees and shrubs planted on the bridge is largely uncontrollable. Conventional ecological bridges are unsuitable for scenarios with large spans and strict limitations on both the bridge deck and substructure height. In addition, conventional ecological bridges also have the following shortcomings: (1) Conventional ecological bridges are mainly planted with low shrubs and herbaceous plants. Although they achieve the basic function of ecological corridor bridges, the landscape and ecological effects are not good.

[0004] (2) If the height of the planting on a conventional ecological bridge is to be increased, the thickness of the soil cover on the bridge needs to be increased, which will increase the bridge load and thus increase the height of the bridge structure. The bridge will look heavier and affect the overall effect. Utility Model Content

[0005] The purpose of this invention is to overcome at least one of the defects of the prior art and provide a controllable height ecological bridge based on a truss structure that is structurally stable, aesthetically pleasing, and has a controllable height.

[0006] The objective of this utility model can be achieved through the following technical solutions: A controllable-height ecological bridge based on a truss structure includes a truss bridge main structure and a planting structure coupled to the truss bridge main structure, wherein... The main structure of the truss bridge includes a bridge deck, an upper chord located above the bridge deck, and a lower chord located below the bridge deck. There are two lower chords symmetrically arranged, and the upper and lower chords are connected by multiple web members. The planting structure includes a first wire mesh, an embedded ecological planting trough, and a shallow planting area. The first wire mesh is located between the web members and the upper chord and between the web members and the lower chord. The embedded ecological planting trough is embedded in the bridge deck, and the shallow planting area is laid on the bridge deck.

[0007] Furthermore, the shallow planting area covers a portion of the bridge deck, while the remaining portion of the bridge deck forms a passageway.

[0008] Furthermore, the shallow planting area is filled with lightweight planting soil.

[0009] Furthermore, the embedded ecological planting troughs are spaced longitudinally on the bridge deck.

[0010] Furthermore, the embedded ecological planting troughs are arranged at equal intervals along the longitudinal direction on the bridge surface.

[0011] Furthermore, a slot is provided on the bridge deck in the area between the two lower chords for embedding the embedded ecological planting trough.

[0012] Furthermore, the grooved and embedded ecological planting troughs are connected by mortise and tenon joints, snap-fit ​​connections, or bolts.

[0013] Furthermore, the planting structure also includes a second wire mesh disposed between each of the web members.

[0014] Furthermore, a canopy is provided on both sides of the upper chord, and a third wire mesh is installed on the canopy.

[0015] Furthermore, railings are installed on both sides of the bridge deck.

[0016] Furthermore, the plants planted on the first, second, and third wire meshes are vine-like plants.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1) This utility model of ecological bridge is composed of a truss bridge main structure and a planting structure coupled together. Combined with an ecological pergola (truss bridge) design, it achieves a perfect integration of structural load-bearing and ecological function. The pergola serves as both the main load-bearing structure, ensuring structural stability, and an ecological functional component, forming a distinctive three-dimensional ecological pergola bridge. The truss components, on the one hand, act as the main load-bearing structure of the bridge; on the other hand, suitable vines can be selected based on species characteristics to achieve a balance and control between the bridge's structural height and the height of the ecological plants, adapting to the needs of different environments and landscapes.

[0018] 2) Wire mesh can be installed between the web members and the upper and lower chords of the truss, on the outside of the web members, and on the roof and other structures to allow vines to climb, guide and restrict their growth, and the height of the entire ecological bridge is controllable.

[0019] 3) Apart from the main load-bearing structure, the truss bridge still has a considerable amount of usable space on the bridge deck. This utility model sets an embedded ecological planting trough at regular intervals on the bridge deck, hiding the green soil within the structure, thereby reducing the thickness of the soil cover above the bridge deck, weakening the size of the ecological bridge, and improving the landscape.

[0020] 4) The shallow planting area of ​​this utility model is filled with lightweight planting soil, which further reduces the weight of the soil, reduces the volume of the bridge structure, and improves the permeability of the bridge. Attached Figure Description

[0021] Figure 1 This is a cross-sectional schematic diagram of the present invention; Figure 2 This is a side view of the present invention; Figure 3 This is a top view of the present invention. Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0023] like Figures 1-3 As shown, this embodiment provides a controllable height ecological bridge based on a truss structure, including a truss bridge main structure and a planting structure coupled to the truss bridge main structure. Through the coupling of the two parts, a perfect combination of structural stress and ecological function is achieved.

[0024] Furthermore, in a specific embodiment, the main structure of the truss bridge includes a bridge deck 5, an upper chord 1 positioned above the bridge deck 5, and a lower chord 2 positioned below the bridge deck 5. Two lower chords 2 are symmetrically arranged, and the upper chord 1 and lower chord 2 are connected by multiple web members 3. The planting structure includes a first wire mesh, an embedded ecological planting trough 4, and a shallow planting area 6. The first wire mesh is positioned between the web members 3 and the upper chord 1, and between the web members 3 and the lower chord 2. The embedded ecological planting trough 4 is embedded in the bridge deck 5, and the shallow planting area 6 is laid on the bridge deck 5. In this embodiment, the first wire mesh is a longitudinal wire mesh.

[0025] Specifically, the shallow planting area 6 covers part of the bridge deck 5, and the remaining part of the bridge deck 5 forms a passage area for pedestrians, motor vehicles, non-motor vehicles, etc.

[0026] Furthermore, in a specific embodiment, the shallow planting area 6 is filled with lightweight planting soil. Specifically, lightweight planting soil is a soil matrix with low bulk density and high permeability, and is an existing soil type applicable to multiple scenarios, used to reduce building load and meet the needs of plant growth. The core characteristics of lightweight planting soil include: 1) Low bulk density: It is usually composed of lightweight materials such as perlite, vermiculite, and coconut coir, and its weight is only about 60% of that of ordinary soil. 2) Good permeability: The loose granular structure allows for rapid drainage, making it suitable for succulents, pothos, and other plants that require good drainage. 3) Water and fertilizer retention: Adding humus or water-retaining agents can balance the supply of water and nutrients.

[0027] Specifically, the embedded ecological planting troughs 4 are arranged longitudinally at intervals on the bridge deck 5. In this embodiment, the embedded ecological planting troughs 4 are arranged at equal intervals longitudinally on the bridge deck 5. The embedded ecological planting troughs 4 can be made of steel or concrete, and can be fabricated on-site or be prefabricated components, depending on the bridge structure.

[0028] In a preferred embodiment, a slot is provided on the bridge deck 5 in the area between the two lower chords 2 for embedding an embedded ecological planting trough 4.

[0029] Specifically, the four slotted and embedded ecological planting troughs are connected by mortise and tenon joints, snap-fit ​​joints, or bolts.

[0030] For example, a combination of a tight-fitting nut and a double-ended bolt is used to create a slotted and embedded ecological planting trough 4. After the nut is embedded in the slot, the double-ended bolts are tightened from both sides of the embedded ecological planting trough to form a bidirectional tensile force, achieving a stable connection.

[0031] In another preferred embodiment, the planting structure further includes a second wire mesh disposed between each of the web members 3. In this embodiment, the second wire mesh is a transverse wire mesh.

[0032] In another preferred embodiment, a canopy 8 is provided on both sides of the upper chord 1, and a third wire mesh is provided on the canopy 8. In this embodiment, the third wire mesh is a longitudinal horizontal wire mesh.

[0033] The aforementioned wire mesh is planted with climbing plants, designed to facilitate their climbing, guide and limit their growth, thus ensuring controllable height of the entire ecological bridge. The mesh size of each wire mesh is determined based on the type of climbing plant. The choice of climbing plants can be made based on project requirements and local characteristics. In specific applications, brightly colored, diverse, and highly climbing climbing plants can be selected to grow on the wire mesh, ensuring the realization of an ecological landscape.

[0034] In another preferred embodiment, railings 7 are provided on both sides of the bridge deck 5.

[0035] In other implementations, the form of the ecological pergola can be adjusted according to functional requirements, structural stress, and landscape requirements.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
