Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, and in particular to municipal road drainage structures. Background Technology

[0002] Public roads within urban planning areas that allow vehicles and pedestrians to pass are a core component of urban infrastructure, serving functions such as traffic management, laying municipal pipelines (water, electricity, gas, communications, etc.), and creating urban landscapes.

[0003] A crucial component of municipal drainage systems, drainage ditches collect and remove rainwater, snowmelt, and surface runoff from roads, sidewalks, and surrounding areas. This prevents waterlogging, roadbed subsidence, and damage to the road structure, ensuring traffic safety and extending road lifespan. Common types include: side ditches (located on the outer side of the shoulder or at the toe of a slope, commonly used on roads without a median, often open ditches), drainage ditches (connecting side ditches and intercepting ditches to direct water to municipal pipe networks or natural water bodies), intercepting ditches (located at the top of road cut slopes or on the outer side of embankment to intercept surface runoff), storm drains (located in low-lying areas of the road surface or beside curbs to collect rainwater and direct it into drainage pipes), and median strip drainage (used on roads with a median strip to collect rainwater within the median strip via infiltration ditches or drainage pipes). Structurally, they are mostly open ditches (made of materials such as concrete, masonry, and brick, with longitudinal slope for drainage) or culverts (buried pipes, such as PVC pipes and concrete pipes, with gratings / covers to prevent blockage). The longitudinal slope inside the ditch is not less than 0.3% to ensure smooth drainage.

[0004] Municipal road drainage ditches become clogged with silt, leaves, and other debris, rendering them ineffective and causing road flooding. This affects vehicle safety (e.g., skidding, rear-end collisions) and pedestrian safety (e.g., slipping and falling). Floodwater seeps into the roadbed, causing softening and subsidence, shortening road lifespan, and increasing maintenance costs. Long-term accumulation of debris can ferment, producing foul odors, attracting mosquitoes, polluting the surrounding environment, and endangering public health. Frequent manual dredging is necessary, consuming significant manpower and resources, and may temporarily occupy the road, impacting traffic flow. Furthermore, silt and debris may flow into downstream stormwater drainage networks, causing systemic blockages, expanding the scope of drainage problems, and increasing the overall difficulty of remediation.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 4As shown, the municipal road drainage structure mainly includes a first drainage ditch 1, a first grating 2, a second drainage ditch 3, and a second grating 4. The first grating 2 covers the upper opening of the first drainage ditch 1, while the second grating 4 is installed at the upper opening of the second drainage ditch 3. The first drainage ditch 1 and the second drainage ditch 3 together form a drainage pipe system along the municipal road, used to collect and guide surface water.

[0015] A transfer drainage ditch 5 is provided between the first drainage ditch 1 and the second drainage ditch 3, and bases 6 are provided at both ends of the transfer drainage ditch 5. The bases 6 and the outside of the transfer drainage ditch 5 form a cavity structure, and the upper end of the cavity is covered with a cap 7 to prevent debris from entering and to facilitate maintenance. An opening 8 is provided in the upper part of the transfer drainage ditch 5, and the inside of the drainage ditch can be cleaned by operating the cap 7 and the opening 8.

[0016] A fixed base 9 is installed at the notch 8, with movable brackets 10 and electric push rods 11 connected to its two sides respectively. The upper end of the electric push rod 11 is connected to the free end of the movable bracket 10 via a rotating shaft, and the two movable brackets 10 are connected by a rotating connecting plate 12. A grid frame 13 is installed below the rotating connecting plate 12 to intercept debris. Both the rotating connecting plate 12 and the grid frame 13 have raising strips 14 on their outer edges to increase their capacity to hold debris, thereby realizing the mechanical and automated cleaning function in the transfer drainage ditch 5.

[0017] Both the opening edges of the first drainage ditch 1 and the second drainage ditch 3 are equipped with baffle structures. The first grille 2 and the second grille 4 are placed on the baffles, ensuring a secure installation and facilitating disassembly and cleaning. The bottoms of the first drainage ditch 1 and the second drainage ditch 3 are designed to be semi-circular to optimize water flow. Both the first grille 2 and the second grille 4 have multiple elliptical through holes, allowing water to flow smoothly into the drainage ditch while effectively blocking larger debris.

[0018] The connection between the first drainage ditch 1, the second drainage ditch 3, and the intermediate drainage ditch 5 is achieved by concrete pouring to fix the structure and ensure hydraulic connection. The base 6 is set at both ends of the intermediate drainage ditch 5, and its opening is also equipped with a retaining strip. The cover 7 is installed above the retaining strip to ensure the structure is sealed and stable.

[0019] The intermediate drainage ditch 5 and the base 6 are integrally cast with concrete, resulting in high structural strength and good durability. The internal cavities of all three are kept at the same width to ensure unobstructed water flow.

[0020] The fixed base 9 is designed in a fan shape and made of stainless steel. During installation, it is inserted into the opening at the upper end of the intermediate drainage ditch 5 and fixed by pouring concrete. The movable bracket 10 consists of two support bars and a rotating shaft. The two support bars are connected by the rotating shaft, and one end of the bracket is connected to the fixed base 9 via the rotating shaft.

[0021] The tail end of the electric push rod 11 is connected to the fixed base 9 via a rotating shaft, and its telescopic end is linked to the movable bracket 10 via a rotating shaft to provide power support. The upper end of the rotating connecting plate 12 is provided with a round rod, and the two ends of the round rod extend to the movable brackets 10 on both sides and are rotatably connected via rotating shafts.

[0022] The bottom of the grid frame 13 is designed to be semi-circular, matching the arc shape of the drainage ditch bottom to improve debris collection efficiency. The grid frame 13 is fixed to the rotating connecting plate 12 by welding. The heightening strips 14 are welded to the edges of the rotating connecting plate 12 and the grid frame 13 to increase the storage capacity for intercepting debris and extend the automatic cleaning operation cycle.

[0023] The transfer drainage ditch 5 and the base 6 are integrally cast with concrete to ensure structural strength and durability. The inner cavity widths of both are kept consistent to guarantee smooth water flow. The connection points between the first drainage ditch 1, the second drainage ditch 3, and the transfer drainage ditch 5 are also constructed with concrete, achieving structural fixation and hydraulic connectivity. All three have the same inner cavity width. A fan-shaped stainless steel fixing seat 9 is inserted into the opening at the upper end of the transfer drainage ditch 5 and fixed with concrete, completing the installation of the fixing seat 9.

[0024] Water from the road surface enters the first drainage ditch 1 and the second drainage ditch 3 through the elliptical holes on the first grid 2 and the second grid 4. The first grid 2 and the second grid 4 block larger debris. The water in the first drainage ditch 1 and the second drainage ditch 3 flows into the transfer drainage ditch 5 through the connecting part (fixed by concrete pouring). The water flows in the transfer drainage ditch 5, and the grid frame 13 (semi-circular at the bottom, matching the arc shape of the bottom of the drainage ditch) intercepts debris in the water. The riser strip 14 increases the storage capacity of intercepted debris and extends the automatic cleaning cycle.

[0025] Operate the electric push rod 11, whose telescopic end drives the movable support 10 (composed of support bars and a rotating shaft, one end of which is connected to the rotating shaft of the fixed base 9) to rotate via a rotating shaft. The rotation of the movable support 10 drives the rotating connecting plate 12 (the upper round rod is connected to the rotating shaft of the movable support 10) to rotate, thereby lifting the welded and fixed bar screen 13 from the water to the gap 8 position. The debris intercepted in the bar screen 13 is lifted to the gap 8, where it is cleaned manually or mechanically; the lifting strip 14 prevents the debris from falling during the lifting process. The electric push rod 11 retracts, causing the movable support 10 and the rotating connecting plate 12 to rotate in the opposite direction, and the bar screen 13 falls back into the intermediate drainage ditch 5, restoring the interception state.
