Description

Technical Field

[0001] This utility model relates to the fields of municipal engineering and rail transit, specifically to an integrated water passage structure. Background Technology

[0002] In the construction of rural roads and scenic roads, water-crossing pavements are a common design, allowing water to flow across the road surface under specific conditions without the need for a complete bridge. This type of structure is built in wide, shallow rivers with little or no water flow to allow water to overflow the road surface during floods. Water-crossing pavements are characterized by low cost, short construction period, and convenient construction, and are particularly suitable for low-grade roads crossing seasonal rivers in southern regions with well-developed water systems.

[0003] Traditional waterway systems have the following drawbacks: (1) Traditional water crossings often cross the water surface directly without water level regulation and control facilities, so they are easily affected by water level changes and pose significant safety hazards.

[0004] (2) Traditional waterways are structurally unstable due to limited construction materials and technology, making them unable to withstand large water flow impacts or long-term hydrogeological effects.

[0005] (3) The capacity of traditional waterways is often limited by the road surface bearing capacity, making it difficult to meet the needs of modern transportation.

[0006] (4) Traditional waterway pipeline layout is difficult, pipelines are prone to corrosion and aging, and maintenance is difficult.

[0007] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0008] In view of the problems in the related technologies, this utility model proposes an integrated water passage structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0009] Therefore, the specific technical solution adopted by this utility model is as follows: An integrated water passage structure, comprising: The structure consists of a retaining wall, with its interior filled with subgrade to enhance the structural stability of the integrated waterway; culverts, located inside the retaining wall, guide the water flow; culvert control components, located at both ends of the culvert, regulate the water flow by controlling the opening degree of the culvert; impact-resistant components, located within the retaining wall and around the culvert, enhance the load-bearing capacity and deformation resistance of the surrounding structure; and a walkway surface, located on top of the subgrade, enables the integrated waterway to function as a passageway.

[0010] Furthermore, in order to extend the service life and enhance the overall structural durability, the retaining wall structure includes a concrete retaining wall base slab, a concrete retaining wall side slab at the top of the concrete retaining wall base slab, a concrete cantilever slab at the top of the concrete retaining wall side slab, and the plain soil is located at the top of the concrete retaining wall base slab.

[0011] Furthermore, in order to improve the passage efficiency of the unit space, the top of the concrete cantilever slab and both ends of the road surface are provided with a permeable brick pavement for the sidewalk, and a railing is provided at the end of the permeable brick pavement for the sidewalk away from the road surface.

[0012] Furthermore, in order to centrally lay various pipelines, integrated pipeline corridors are set up at the internal corners of the retaining wall structure.

[0013] Furthermore, in order to regulate the water level, the culvert control assembly includes electric gate valves installed at both ends of the culvert, and the electric gate valves are connected to the PLC control system.

[0014] Furthermore, in order to improve the load-bearing capacity and deformation resistance of the surrounding structure of the culvert, the impact-resistant components include hidden columns and hidden beams installed around the culvert; the longitudinal spacing of the hidden columns is consistent with the spacing of the culvert, and the hidden beams are continuously arranged along the top of the culvert and the bottom plate of the concrete retaining wall.

[0015] The beneficial effects of this utility model are as follows: This utility model adopts a U-shaped concrete retaining wall structure, combined with the water flow guidance design of the culvert and the method of separating people and vehicles, solving many shortcomings of traditional water passage structures and broadening the application scenarios of water passage structures. The structure is robust, has good integrity, high load-bearing capacity, and has the function of automatically adjusting the water level on both sides, effectively solving the problems of poor safety, poor stability, limited traffic capacity, and difficult pipeline maintenance of traditional water passages. Through innovative design and optimized construction, the integrated water passage structure effectively solves the inherent defects of traditional water passages in terms of water level control, structural stability, traffic capacity, and pipeline maintenance, significantly improving the overall technical effect. Specifically, it includes: (1) Enhanced water level regulation capability improves traffic safety: By using pre-embedded concrete culverts as water flow channels, and by controlling the opening degree of the culverts or using valves to adjust the water flow, the water level can be regulated. This avoids the problem of traditional waterways being easily affected by water level changes due to the lack of water level regulation facilities, and significantly reduces safety hazards.

[0016] (2) Improved structural stability and enhanced load-bearing and impact resistance: A U-shaped concrete retaining wall structure was adopted, with concealed columns and beams reinforcing the perimeter of the culvert, effectively improving the load-bearing capacity and deformation resistance of the surrounding structure. Waterproof and impermeable concrete was used, and the backfill soil was compacted in layers using small machinery. Above the concrete base slab was the backfill soil and the road surface structure. The road surface and the retaining wall were compacted together. These measures together ensured the stability of the overall structure, enabling it to better withstand the impact of large water flows and long-term hydrogeological effects.

[0017] (3) Optimize traffic capacity to meet diverse traffic needs: A concrete cantilever slab is installed on the outer side of the concrete retaining wall side panel, and a pedestrian pavement structure and railings are installed above the concrete cantilever slab. This allows the integrated waterway structure to serve as both a vehicular and pedestrian walkway, optimizing traffic organization, improving traffic efficiency per unit space, and better meeting the needs of modern transportation.

[0018] (4) Improve pipeline layout and maintenance to reduce operating costs: A mezzanine is constructed at the corner of the concrete retaining wall base slab to serve as a comprehensive utility tunnel, providing an orderly space for laying various pipelines (such as water supply, drainage, electricity, and communications), thus solving the problem of difficult pipeline layout under traditional water passages. The centralized arrangement of pipelines within the comprehensive utility tunnel not only reduces the impact of external environmental corrosion and aging on the pipelines but also significantly reduces the difficulty and cost of later maintenance.

[0025] With the help of the above solutions, this utility model enhances water level regulation capabilities, improves traffic safety, increases structural stability, enhances load-bearing and impact resistance, optimizes traffic capacity to meet diverse traffic needs, and improves pipeline layout and maintenance, reducing operating costs.

[0026] In one embodiment, the retaining wall structure 1 includes a concrete retaining wall base slab 101, a concrete retaining wall side slab 102 at the top of the concrete retaining wall base slab 101, a concrete cantilever slab 103 at the top of the concrete retaining wall side slab 102, and the subgrade 2 is located at the top of the concrete retaining wall base slab 101. The retaining wall structure 1 is constructed using waterproof and impermeable concrete, which effectively blocks water penetration, prevents corrosion and aging of the concrete structure due to long-term immersion, extends its service life, and enhances the overall durability of the structure.

[0027] In one embodiment, for the aforementioned concrete cantilever slab 103, a permeable brick pavement layer 7 is provided at both ends of the concrete cantilever slab 103 and at both ends of the walkway surface 6, and a railing 8 is provided at the end of the permeable brick pavement layer 7 away from the walkway surface 6. The integrated waterway structure simultaneously provides both a driveway and a walkway, optimizing traffic organization, improving traffic efficiency per unit space, and better meeting the needs of modern transportation.

[0028] In one embodiment, for the above-mentioned retaining wall structure 1, a pipeline integrated gallery 9 is provided at the inner corner of the retaining wall structure 1 for centralized laying of various pipelines (such as water supply and drainage, power, communication, etc.), which solves the problems of difficult pipeline layout, easy corrosion and aging, and inconvenient maintenance in traditional water passages.

[0030] In one embodiment, the impact-resistant component 5 includes concealed columns 501 and concealed beams 502 arranged around the culvert 3; the longitudinal spacing of the concealed columns 501 is consistent with the spacing of the culvert 3, and the concealed beams 502 are continuously arranged along the top of the culvert 3 and the bottom plate of the concrete retaining wall 101, which effectively improves the load-bearing capacity and deformation resistance of the structure around the culvert.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] An integrated waterway structure includes a U-shaped concrete retaining wall structure 1. Along the longitudinal direction of the retaining wall structure 1, a precast concrete culvert 3 is embedded transversely at regular intervals. The culvert 3 serves as a channel for water flow, and the water flow rate can be adjusted by controlling the opening degree of the culvert 3 or using valves, thereby regulating the water level. The culvert 3 is reinforced around its perimeter with concealed columns and beams. A mezzanine is constructed at the corner of the concrete retaining wall base slab 101 to serve as a utility tunnel 9. Above the concrete retaining wall base slab 101 is backfilled soil 2 and a road surface structure (road surface 6). The road surface and the retaining wall structure 1 are compacted together. A concrete cantilever slab 103 is installed on the outer top of the concrete retaining wall side slab 102. Above the concrete cantilever slab 103 is a pedestrian pavement structure (permeable brick surface layer 7) and railings 8. The soil 2 backfill is compacted in layers using small machinery. Waterproof and impermeable concrete is used.

[0033] This utility model includes: (1) Design of water level regulation and water flow management.

[0034] The retaining wall structure 1, constructed entirely of U-shaped concrete, combined with the water flow guiding effect of the culvert 3, reduces the impact of water flow on the structure. Simultaneously, the structure's shape facilitates uniform water flow, improving the efficiency and stability of the water passage. Precast concrete culverts 3 are embedded transversely at intervals along the longitudinal direction of the retaining wall structure 1. As the core channel for water flow, the culverts 3 allow for active regulation of water flow by controlling their opening degree or by configuring valves, thereby achieving water level control and effectively avoiding safety hazards caused by water level changes in traditional water passages.

[0035] (2) Measures to enhance structural stability.

[0036] Around the retaining wall structure 1 at the location of culvert 3, hidden columns 501 and hidden beams 502 are added to strengthen the structure, improving the load-bearing capacity and deformation resistance of this area to cope with the impact of water flow and long-term hydrogeological effects on the structure. The main structure is constructed with waterproof and impermeable concrete, which effectively blocks water penetration, prevents corrosion and aging of the concrete structure due to long-term immersion, extends its service life, and enhances the overall durability of the structure.

[0037] (3) Optimization of traffic and space utilization.

[0038] Layered pavement structure design: Plain soil 2 is backfilled on top of the concrete retaining wall base slab 101 (compacted in layers using small machinery), and a road surface structure is constructed to enable the waterway to also function as a passageway; a concrete cantilever slab 103 is set on the outer side of the concrete retaining wall side slab 102, and a permeable brick pavement layer 7 and railings 8 are constructed on top of the concrete cantilever slab 103 to separate pedestrians and vehicles and improve traffic safety and capacity.

[0039] Coordinated stabilization treatment of road surface and retaining wall structure 1: The road surface 6 and retaining wall structure 1 are compacted and squeezed to enhance the overall connection between the road surface and retaining wall structure 1, avoid road surface cracking or structural instability caused by uneven settlement, and ensure that the traffic bearing capacity meets the needs of modern traffic.

[0040] (4) Innovation in integrated pipeline layout.

[0041] A mezzanine is specially designed at the corner of the concrete retaining wall base slab 101 as a pipeline integrated gallery 9, which is used to centrally lay various pipelines (such as water supply and drainage, power, communication, etc.). This solves the problems of difficult pipeline layout, easy corrosion and aging, and inconvenient maintenance in traditional water passages, and facilitates unified management, maintenance and replacement of pipelines, thereby improving the overall practicality of the project.

[0042] This utility model includes a main frame (a combination of a main U-shaped concrete retaining wall structure 1 and a precast culvert) and a water level regulation and passage function module.

[0043] (1) Main frame: U-shaped concrete retaining wall structure 1 combined with culvert 3.

[0044] The U-shaped concrete retaining wall structure 1 is constructed using reinforced concrete. A culvert 3 (within diameter determined by the design flow rate, e.g., DN800-DN1200mm) is pre-embedded every 5-10 meters along the longitudinal direction (in the direction of water flow). Both ends of the culvert 3 extend beyond the concrete retaining wall side panels 102, forming a continuous water flow channel. Hidden columns 501 and hidden beams 502 are added at the locations of the culvert 3 for reinforcement. The longitudinal spacing of the hidden columns 501 matches the spacing of the culvert 3, and the hidden beams 502 are continuously arranged along the top and bottom of the culvert 3 to enhance the overall impact resistance.

[0045] Concrete retaining wall base slab 101 and road system: The concrete retaining wall base slab 101 is a waterproof and seepage-resistant concrete base slab (thickness ≥ 500 mm). A utility tunnel 9 is reserved at the corner of the concrete retaining wall base slab 101 for laying water supply, drainage, power, and communication pipelines. The concrete retaining wall base slab 101 is backfilled with layers of plain soil 2 (compaction coefficient ≥ 0.96), and the surface is paved with a road surface 6 (e.g., 200 mm thick C30 concrete + 100 mm graded crushed stone base). The gap between the road surface 6 and the retaining wall structure 1 is filled using a compaction method to prevent uneven settlement.

[0046] (2) Water level regulation and passage function module.

[0047] Culvert Control Component 4: Each culvert 3 is equipped with an electric gate valve 401 (with a PLC control system) at both ends. The flow rate is controlled by adjusting the valve opening degree, achieving real-time water level regulation (e.g., closing part of the culvert 3 during the dry season to raise the road surface water level, and fully opening the culvert 3 during the flood season to accelerate flood discharge). The electric gate valve 401 is linked with the water level sensor, and automatically opens the backup culvert 3 when the water level exceeds the warning value (e.g., 300mm below the road surface).

[0048] Mixed pedestrian and non-motorized vehicle design: The outer side of the retaining wall structure 1 has a cantilevered concrete slab 103. A 100mm thick permeable brick surface layer 7 for the sidewalk and railings 8 are laid on top of the concrete slab 103 to form an independent sidewalk that is physically separated from the roadway and improves traffic safety.
