Description

Technical Field

[0001] The present invention relates to the technical field of bridges, and particularly to a bridge structure with pipelines, sidewalks and green belts. Background Art

[0002] In urban road construction, various pipelines such as electricity, water supply and drainage, heating, and communication usually need to be laid along the road. When facing the situation where pipelines cross a river, the solution of setting external pipeline brackets on the bridge is adopted, but there are problems such as poor durability, expansion capacity and aesthetics of the brackets.

[0003] Subsequently, the practice of placing pipelines on the bridge emerged. For example, the Chinese utility model patent with the authorization announcement number CN217997820U and the authorization announcement date of December 9, 2022 discloses an assembled sidewalk structure and a bridge, including: a precast road structure laid on a road surface structure, the precast road structure including a first precast member and a second precast member arranged side by side, the first precast member having a wire threading channel, and the second precast member having a water flow channel; a water collection structure arranged on the road surface structure on the side of the precast road structure for collecting the accumulated water on the road surface structure; and a diversion structure arranged between the water collection structure and the water flow channel for diverting the accumulated water from the water collection structure to the water flow channel. The first precast member includes a first groove plate having a first groove cavity, and the first groove cavity covers the road surface structure to form a wire threading channel; the second precast member includes a second groove plate having a second groove cavity, and the second groove cavity covers the road surface structure to form a water flow channel.

[0004] When overhauling the pipelines in the existing assembled sidewalk structure and bridge, removing the precast members easily disturbs the internal pipelines, and the subsequent installation is difficult; in addition, for the case where there is a green belt on the bridge, the green belt located between the motor vehicle lane and the sidewalk will block the road surface drainage and cannot meet the requirement of smoothly draining the accumulated water in the green belt. Summary of the Invention

[0005] The technical problems to be solved by the present invention are: removing the precast members easily disturbs the internal pipelines, and the subsequent installation is difficult; for the case where there is a green belt on the bridge, the green belt located between the motor vehicle lane and the sidewalk will block the road surface drainage and cannot meet the requirement of smoothly draining the accumulated water in the green belt.

[0006] To solve the above technical problems, the present invention provides a technical solution for a bridge structure with pipelines, sidewalks and green belts:

[0007] The bridge structure with pipelines, sidewalks and green belts includes a bridge main body, a first pedestal, a second pedestal, a green belt retaining platform, a sidewalk slab, a water guiding partition beam and a green belt drain pipe.

[0015] Furthermore, a waterproof protective layer is provided on the upper side of the bridge body corresponding to the wiring space, and the waterproof protective layer is composed of a polyurethane waterproof coating and a cement mortar layer.

[0016] Furthermore, a hanging groove is provided inside the sidewalk slab, the hanging part is a pre-buried hanging ring arranged in the hanging groove, a cover cap is installed on the upper side of the hanging groove, and the cover cap is detachably connected to the sidewalk slab.

[0017] Furthermore, the edge of the sidewalk slab is provided with a steel edging, the steel edging protrudes from the upper side of the sidewalk slab, and embedded parts are connected between the steel edging and the sidewalk slab. The upper side of the sidewalk slab is paved with anti-slip tiles, and the steel edging is lower than or flush with the upper surface of the anti-slip tiles.

[0018] Furthermore, a transition inclined shaft is connected to the outer side of the bridge body, and the transition inclined shaft extends obliquely downward toward the side away from the bridge body. The transition inclined shaft is connected to the wiring space so that the pipeline can be introduced below the ground. A cushion layer is provided on the lower side of the transition inclined shaft, and walking steps are also provided on the upper part of the transition inclined shaft. The walking steps are arranged step by step from the sidewalk slab to the ground.

[0019] Furthermore, a bridge deck beam is provided at the end of the bridge body near the sidewalk slab, and the bridge structure also includes a roadbed beam provided on the outside of the bridge body, and the bridge deck beam and the roadbed beam are arranged at intervals; the edge of the roadbed beam is provided with a first angle steel, and the edge of the bridge deck beam is provided with a second angle steel, a joint steel plate is installed on the upper side of the first angle steel, and the joint steel plate is overlapped on the upper side of the second angle steel, and a guard steel plate is also provided on the bridge deck beam near the second angle steel, and the joint steel plate and the guard steel plate are arranged at intervals.

[0020] Compared with the prior art, the bridge structure with pipelines, sidewalks and green belts of the present invention has the following beneficial effects: the bridge structure with pipelines, sidewalks and green belts adopts the design form of a bridge body, a first base, a second base, a green belt baffle, a sidewalk slab, a water guide beam and a green belt drainage pipe. The first base, the second base and the green belt baffle are arranged on the bridge body with transverse intervals, and the sidewalk slab can be detachably installed on the upper side of the first base and the second base. The water guide beam is protrudingly arranged on the upper side of the bridge body and extends between the first base and the second base. The sidewalk slab and the water guide beam are arranged at intervals up and down to form a wiring space. A hidden wiring space is formed by the sidewalk slab and the water guide beam, which not only protects the pipelines from the external environment, but also facilitates the disassembly of the sidewalk slab to inspect and repair the pipelines, avoids the internal pipelines being easily disturbed by the removal of prefabricated components, and reduces the difficulty of subsequent installation.

[0021] Among them, pipelines are arranged in the wiring space, and the pipelines are erected on the upper side of the water guide partition beam, preventing the pipelines from directly contacting the bridge surface water accumulation and improving the safety of the pipelines; a plurality of water guide partition beams are longitudinally arranged at intervals, and the intervals between adjacent two water guide partition beams form water guide grooves, and the water guide grooves are communicated between the through holes and the drain holes. The water guide partition beam has the dual functions of supporting pipelines and draining and guiding water, reducing additional components. The water guide grooves formed by adjacent water guide partition beams can quickly guide the rainwater on the bridge surface to the drain holes, and the convex design of the water guide partition beam avoids the accumulation of sundries in the rainwater from blocking the water guide grooves, ensuring smooth drainage.

[0022] In addition, a green belt space is formed between the green belt retaining platform and the second base. The green belt retaining platform is provided with water inlet holes, and the green belt drain pipes are connected between the water inlet holes and the through holes. The pipe walls of the green belt drain pipes are provided with water permeable holes, and a soil filtering layer is wrapped outside the green belt drain pipes. The water inlet holes of the green belt retaining platform can allow the rainwater on the road surface to enter the green belt drain pipes and the water guide grooves, preventing the green belt from blocking the road surface drainage due to being located between the motor vehicle lane and the sidewalk. The rainwater in the green belt is collected into the green belt drain pipes through the water permeable holes, and then can smoothly flow into the drain holes through the water guide grooves, meeting the requirement of smoothly draining the accumulated water in the green belt. The combination of the water permeable holes and the soil filtering layer can effectively prevent soil loss, enabling the green belt soil to accumulate an appropriate amount of water while avoiding excessive water accumulation from causing the roots of the green plants to rot.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] As Figures 1 to 5 shown, a bridge structure with pipelines, sidewalks and green belts according to an embodiment of the present invention includes a bridge main body 1, a first base 2, a second base 3, a green belt retaining platform 4, a sidewalk slab 5, a water guiding partition beam 6 and a green belt drain pipe 7. The first base 2, the second base 3 and the green belt retaining platform 4 are horizontally spaced on the bridge main body 1, and the sidewalk slab 5 is detachably installed on the upper sides of the first base 2 and the second base 3; the water guiding partition beam 6 protrudes from the upper side of the bridge main body 1 and extends between the first base 2 and the second base 3. The sidewalk slab 5 and the water guiding partition beam 6 are vertically spaced to form a wiring space 12, and pipelines 21 are arranged in the wiring space 12, and the pipelines 21 are erected on the upper side of the water guiding partition beam 6.

[0034] A plurality of water guiding partition beams 6 are longitudinally spaced. The interval between two adjacent water guiding partition beams 6 forms a water guiding groove 61. A through hole 31 is opened on the lower side of the second base 3, and a drain hole 11 is opened on the bridge main body 1 near the first base 2. The water guiding groove 61 communicates between the through hole 31 and the drain hole 11; a green belt space 13 is formed between the green belt retaining platform 4 and the second base 3. An inlet hole 41 is opened on the green belt retaining platform 4. The green belt drain pipe 7 is connected between the inlet hole 41 and the through hole 31. Water permeable holes 71 are opened on the pipe wall of the green belt drain pipe 7, and a soil filtering layer 72 is wrapped outside the green belt drain pipe 7.

[0035] The bridge structure with pipelines, sidewalks and green belts adopts the design forms of the bridge main body 1, the first base 2, the second base 3, the green belt retaining platform 4, the sidewalk slab 5, the water guiding partition beam 6 and the green belt drain pipe 7. The first base 2, the second base 3 and the green belt retaining platform 4 are horizontally spaced on the bridge main body 1, and the sidewalk slab 5 is detachably installed on the upper sides of the first base 2 and the second base 3. The water guiding partition beam 6 protrudes from the upper side of the bridge main body 1 and extends between the first base 2 and the second base 3. The sidewalk slab 5 and the water guiding partition beam 6 are vertically spaced to form a wiring space 12. A hidden wiring space 12 is formed by the sidewalk slab 5 and the water guiding partition beam 6, which not only protects the pipelines 21 from the external environment, but also facilitates the disassembly of the sidewalk slab 5 for the maintenance of the pipelines 21, avoiding the disturbance of the internal pipelines 21 caused by the removal of prefabricated components and reducing the difficulty of subsequent installation.

[0036] Among them, pipelines 21 are arranged in the wiring space 12. The pipelines 21 are installed on the upper side of the water guide partition beam 6, preventing the pipelines 21 from directly contacting the bridge surface water accumulation, and improving the safety of the pipelines 21. A plurality of water guide partition beams 6 are longitudinally arranged at intervals. The interval between two adjacent water guide partition beams 6 forms a water guide groove 61, and the water guide groove 61 communicates between the through hole 31 and the drain hole 11. The water guide partition beam 6 has dual functions of supporting the pipelines 21 and draining and guiding water, reducing additional components. The water guide groove 61 formed by adjacent water guide partition beams 6 can quickly guide the bridge surface rainwater to the drain hole 11. The convex design of the water guide partition beam 6 avoids the accumulation of sundries in the rainwater from blocking the water guide groove 61, ensuring smooth drainage.

[0037] In addition, a green belt space 13 is formed between the green belt retaining platform 4 and the second base 3. The green belt retaining platform 4 is provided with a water inlet hole 41. The green belt drain pipe 7 is connected between the water inlet hole 41 and the through hole 31. The pipe wall of the green belt drain pipe 7 is provided with water permeable holes 71, and a soil filtering layer 72 is wrapped outside the green belt drain pipe 7. The water inlet hole 41 of the green belt retaining platform 4 allows the road surface rainwater to enter the green belt drain pipe 7 and the water guide groove 61, preventing the green belt from blocking the road surface drainage due to its position between the motor vehicle lane and the sidewalk. The rainwater in the green belt is collected through the water permeable holes 71 into the green belt drain pipe 7, and then can smoothly flow into the drain hole 11 through the water guide groove 61, meeting the requirement of smoothly draining the accumulated water in the green belt. The combination of the water permeable holes 71 and the soil filtering layer 72 can effectively prevent soil loss, enabling the green belt soil to accumulate an appropriate amount of water while avoiding excessive water accumulation causing the roots of the green plants to rot.

[0038] In this embodiment, a first convex platform 20 is arranged on one side of the first base 2 close to the wiring space 12, and a second convex platform 30 is arranged on one side of the second base 3 close to the wiring space 12. The sidewalk slab 5 is lapped on the upper sides of the first convex platform 20 and the second convex platform 30, and the sidewalk slab 5 is also provided with a lifting part 51. The first convex platform 20 of the first base 2 and the second convex platform 30 of the second base 3 can stably support the sidewalk slab 5, and the sidewalk slab 5 can be quickly and flexibly lifted and disassembled by using the lifting part 51, making the pipeline maintenance operation more convenient.

[0039] As a further preferred scheme, the height of the first convex platform 20 is greater than the height of the second convex platform 30. The sidewalk slab 5 extends obliquely downward from the first base 2 to the second base 3, and the lateral slope of the sidewalk slab 5 ≤ 5%. A water outlet hole is provided at the sidewalk slab 5 close to the second base 3. Designing the sidewalk slab 5 as an inclined plane with a lateral slope can make the rainwater on the sidewalk flow towards the inner side of the bridge surface, enter the wiring space 12 through the water outlet hole, and then converge and flow into the drain hole 11 along the water guide groove 61, thus avoiding the problem of water accumulation on the sidewalk.

[0040] Specifically, the soil filtration layer 72 includes a gravel layer 721, a sand and gravel layer 722, and a geotextile layer 723. The gravel layer 721, the sand and gravel layer 722, and the geotextile layer 723 are sequentially arranged on the outer side of the wall of the green belt drain pipe 7 from the inside to the outside. A plurality of water permeable holes 71 are arranged at intervals along the length direction of the green belt drain pipe 7. It should be noted that three or four water permeable holes 71 are arranged every 50 mm, and the three or four water permeable holes 71 are arranged at intervals circumferentially around the wall of the green belt drain pipe 7; the thickness of the gravel layer 721 is 2 cm, the thickness of the sand and gravel layer 722 is 1 mm to 4 mm, and the specification of the geotextile layer 723 is 300 to 400 g / m 2 . The rainwater in the green belt is filtered and decontaminated in three layers by the geotextile layer 723, the sand and gravel layer 722, and the gravel layer 721, ensuring the water permeability rate and sediment retention effect of the green belt.

[0041] Among them, the bridge structure further includes a bearing 14. The bearing 14 is arranged at intervals between the first base 2 and the second base 3. The bearing 14 is in supporting cooperation with the sidewalk slab 5. A water passing hole 141 is opened on the lower side of the bearing 14, and the water passing hole 141 is communicated with the water guide groove 61. By arranging the bearing 14 between the first base 2 and the second base 3, it can play an auxiliary supporting role for the horizontally arranged sidewalk slabs 5, ensuring the width of the sidewalk pavement and the stable supporting force of the sidewalk slabs 5. A through hole 31 of the second base 3 and a water passing hole 141 of the bearing 14 are both arranged one every 5 m longitudinally. A drain hole 11 is arranged one every 5 m longitudinally on the bridge main body 1. A rainwater bucket 17 is installed at the drain hole 11, which can collect the rainwater on the bridge into the longitudinal drain pipe and finally enter the municipal pipe network at the bridge head.

[0042] As a further preferred solution, a waterproof protective layer 15 is arranged on the upper side of the bridge main body 1 corresponding to the wiring space 12. The waterproof protective layer 15 is composed of a polyurethane waterproof coating and a cement mortar layer. The polyurethane waterproof coating is coated on the upper surface of the bridge main body 1, and the thickness of the polyurethane waterproof coating is 1.5 mm. The cement mortar layer is laid on the upper side of the polyurethane waterproof coating, and the thickness of the cement mortar layer is 20 mm, taking into account the functions of preventing rainwater leakage and erosion damage.

[0043] In this embodiment, a steel edge 52 is provided at the edge of the sidewalk slab 5. The steel edge 52 protrudes above the sidewalk slab 5. An embedded part 53 is also connected between the steel edge 52 and the sidewalk slab 5. Anti-slip floor tiles 54 are laid on the upper side of the sidewalk slab 5, and the steel edge 52 is lower than or flush with the upper surface of the anti-slip floor tiles 54. A lifting groove 55 is formed inside the sidewalk slab 5. The lifting part 51 is an embedded lifting ring arranged in the lifting groove 55. A cap 56 is installed on the upper side of the lifting groove 55, and the cap 56 is detachably connected to the sidewalk slab 5. An 8 cm * 8 cm square area centered on the embedded lifting ring is left empty without laying cement mortar and anti-slip floor tiles 54. The cap 56 is a stainless steel cap 56 with a length of 8 cm, a width of 8 cm, and a height of 4 cm, and the cap 56 is fixedly connected to the sidewalk slab 5 by bolts, and the cap 56 is flush with the anti-slip floor tiles 54.

[0044] In addition, a transition inclined shaft 8 is connected to the outside of the bridge main body 1. The transition inclined shaft 8 extends obliquely downward away from the bridge main body 1. The transition inclined shaft 8 is communicated with the wiring space 12 to ensure that the pipeline 21 can be smoothly led from underground to the bridge and from the bridge into the underground, so that the pipeline 21 forms a smooth connection transition on the bridge and underground. Moreover, the transition inclined shaft 8 adopts an obliquely downward design with a slope ratio of 1:3, and the burial depth of the lower opening of the transition inclined shaft 8 is not less than 0.5 m, so that the pipeline can be smoothly buried underground along the transition inclined shaft 8 to meet the covering soil thickness. The two ends of the transition inclined shaft 8 are respectively provided with a first horizontal section and a second horizontal section, and the lengths of the first horizontal section and the second horizontal section are both 0.5 m. The transition inclined shaft 8, the first horizontal section and the second horizontal section respectively have box channels.

[0045] It should be noted that a rubber cushion block 83 is also provided between the pipeline 21 and the transition inclined shaft 8 to prevent the pipeline from being damaged due to collision. A cushion layer 81 is arranged on the lower side of the transition inclined shaft 8. A walking step 82 and a ramp are also provided on the upper part of the transition inclined shaft 8. The walking step 82 is arranged step by step from the sidewalk slab 5 to the ground in a decreasing manner. The design of the walking step 82 and the ramp can meet the barrier-free passage needs of pedestrians and non-motor vehicles.

[0046] At the end of the bridge main body 1, a bridge deck cross beam 16 is arranged close to the sidewalk slab 5. The bridge structure further includes a subgrade cross beam 9 arranged outside the bridge main body 1. The bridge deck cross beam 16 and the subgrade cross beam 9 are arranged at intervals. The edge of the subgrade cross beam 9 is wrapped with a first angle steel 91, and the edge of the bridge deck cross beam 16 is wrapped with a second angle steel 161. A joint steel plate 92 is installed on the upper side of the first angle steel 91, and the joint steel plate 92 overlaps the upper side of the second angle steel 161. A fender steel plate 162 is also provided at the bridge deck cross beam 16 close to the second angle steel 161. The joint steel plate 92 and the fender steel plate 162 are arranged at intervals. The distance between the first angle steel 91 and the second angle steel 161 is the width of the crack between the bridge deck cross beam 16 and the subgrade cross beam 9. The crack is effectively covered by the joint steel plate 92. The clear distance between the joint steel plate 92 and the fender steel plate 162 is not less than the width of the crack. When the bridge undergoes temperature deformation, the joint steel plate 92 can move freely and always reliably block the crack, ensuring the aesthetics and safety at the crack.

[0047] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
