Description

Technical Field

[0001] This utility model relates to the field of highway bridge deck drainage, specifically to a highway engineering bridge deck drainage filtration unit and drainage structure. Background Technology

[0002] In highway engineering, the design and performance of bridge deck drainage structures play a crucial role in the durability of bridges and driving safety. Traditional bridge deck drainage structures often have several problems. On the one hand, drainage efficiency is low. Bridges have a certain height, and water accumulated on the bridge deck cannot be effectively collected and drained in a timely manner. This can easily form a water film when vehicles are traveling at high speeds, reducing tire-road friction and increasing driving safety hazards. For example, during heavy rainfall, a large amount of rainwater accumulates on the bridge deck in a short time, and existing drainage structures cannot quickly drain it, leading to severe road flooding. On the other hand, rainwater on the bridge deck inevitably contains debris, which is also carried away by the rainwater. For example, when rainwater flows across the bridge deck, it inevitably carries various debris such as leaves and pebbles into the drainage pipes. If this debris accumulates in the pipes, it will affect drainage implementation and may even cause blockages, rendering the drainage system ineffective. The current drainage system uses a simple combination of horizontal and vertical PVC pipes. Because the pipes lack filtration systems for debris, they are prone to clogging. Furthermore, the lack of effective filtration and cleaning mechanisms necessitates frequent manual cleaning, resulting in significant manpower and time costs. In addition, the installation and maintenance of the existing drainage structure are inconvenient. The complex connections between the drainage components require substantial manpower and time for installation, and the high precision required further complicates the process. Utility Model Content

[0003] Therefore, to address the aforementioned shortcomings, this utility model provides a bridge deck drainage and filtration unit and drainage structure for highway engineering. The rainwater spherical filtration unit comprises an upper hemispherical filtration component and a lower hemispherical filtration component, which are movably connected. This also facilitates the connection of the upper and lower vertical drainage pipes, and allows for the individual removal of either the upper or lower hemispherical filtration component. During implementation, this application filters and collects impurities mixed in with the rainwater through the filter screen, and the rainwater then flows through the bottom of the lower vertical drainage pipe into the drainage ditch for discharge.

[0004] This utility model is implemented as follows: a bridge deck drainage filtration unit for highway engineering is constructed, characterized in that it is installed in the bridge deck drainage pipeline. The filtration unit is a rainwater spherical filtration unit, which consists of an upper hemispherical filtration component and a lower hemispherical filtration component. The upper hemispherical filtration component includes an upper connecting pipe and an upper hemispherical cover, and the lower hemispherical filtration component includes a lower connecting pipe and a lower hemispherical body. A filter screen is installed inside the lower hemispherical body.

[0005] A bridge deck drainage structure for highway engineering is characterized by comprising: a longitudinal drainage pipe arranged horizontally along the bridge deck; multiple sets of drainage pipes arranged horizontally along the bridge deck; an upper vertical drainage pipe connected below the longitudinal drainage pipe; a rainwater spherical filter unit; a lower vertical drainage pipe arranged vertically along the bridge deck piers; and a drainage ditch located at the bottom of the bridge deck piers. Each set of drainage pipes is horizontally installed at the edge of the bridge deck carriageway. The longitudinal drainage pipe is connected to the corresponding upper vertical drainage pipe. The rainwater spherical filter unit comprises an upper hemispherical filter assembly and a lower hemispherical filter assembly. The upper hemispherical filter assembly includes an upper connecting pipe and an upper hemispherical cover. The lower hemispherical filter assembly includes a lower connecting pipe and a lower hemisphere. A filter screen is installed inside the lower hemisphere. The filter screen can filter and collect impurities mixed in the rainwater. The rainwater is then collected at the bottom of the lower vertical drainage pipe and discharged into the drainage ditch.

[0006] The upper connecting pipe is used to connect to the lower end of the upper vertical drain pipe via a threaded connection. The lower port of the upper hemispherical cover is connected to the upper port of the lower hemispherical body via a threaded connection or a snap-fit ​​connection. The lower end of the lower connecting pipe is used to connect to the upper port of the lower vertical drain pipe via a threaded connection. The water is collected at the bottom of the lower vertical drain pipe and then flows into the drainage ditch. The rainwater spherical filter unit itself consists of two parts: an upper hemispherical filter assembly and a lower hemispherical filter assembly. These two parts are movably connected, which also facilitates the docking of the upper and lower vertical drain pipes. The upper or lower hemispherical filter assembly can also be removed separately.

[0007] According to the drainage structure of the highway bridge deck described in this utility model, the bridge deck is characterized by: a 10cm thick C40 concrete bridge deck pavement base layer being laid on the bridge deck carriageway slab, a 10cm thick asphalt concrete surface layer being laid on the base layer, and a waterproof bonding layer being provided between the base layer and the surface layer of the bridge deck pavement.

[0008] The drainage pipe has a large-diameter inlet end and a curved outlet end. The asphalt concrete surface layer forms a rainwater sloping edge collection cavity at the end edge above the bottom layer of the C40 concrete bridge deck pavement. The lower side of the large-diameter inlet end is a sealed surface, and the upper side of the sealed surface is the inlet. The sealed surface is flush with the bottom layer of the C40 concrete bridge deck pavement, and the inlet corresponds exactly to the collection cavity.

[0009] The discharge end is connected to the corresponding longitudinal drain pipe.

[0010] According to the highway engineering bridge deck drainage structure of this utility model, the bridge deck drainage is characterized in that: the drainage from the bridge deck is collected by the side ditch of the inclined collection cavity and flows into the drainage hole for discharge; the spacing between the drainage pipes is set at 5m; and additional bridge deck drainage pipes are added at the bottom of the concave vertical curve as appropriate.

[0011] According to the highway engineering bridge deck drainage structure of this utility model, the upper vertical drainage pipe and the lower vertical drainage pipe are fixed by clamps.

[0012] According to the highway engineering bridge deck drainage structure of this utility model, the rainwater spherical filter unit is installed as a whole at the bridge deck abutment or near the bottom or underside of the pier.

[0013] This application offers several significant advantages. In terms of drainage filtration, the rainwater spherical filter unit is ingeniously designed. Its unique movable connection between the upper and lower hemispherical filter components facilitates easy connection with the upper and lower vertical drain pipes, making installation and use convenient. Furthermore, when the filter screen inside the lower hemisphere collects a large amount of debris and needs cleaning, either the upper or lower hemispherical filter component can be removed individually, simplifying operation and greatly improving maintenance efficiency. The filter screen efficiently filters and collects debris mixed in rainwater, effectively preventing debris from entering the drainage pipes, ensuring smooth drainage, significantly improving drainage efficiency, reducing drainage problems caused by debris blockage, and extending the service life of the drainage system. From the overall layout of the drainage structure, the drainage design on the bridge deck driveway slab is scientifically sound and reasonable. The large-diameter inlet and curved outlet design of the drainage pipes, combined with the rainwater collection chamber formed at the upper edge of the C40 concrete bridge deck pavement underlayer, allows for rapid and effective collection of water accumulated on the bridge surface and its discharge through the drainage pipes. Regarding ease of installation and maintenance, the upper and lower vertical drainage pipes are secured with clamps, making installation simple and quick, convenient for construction personnel, and reducing installation difficulty. The rainwater spherical filter unit can be installed as a whole on the bridge deck abutment, or near the bottom of the piers, making full use of the available space in these areas and facilitating disassembly for cleaning filtered debris, making maintenance easier and more efficient. Furthermore, a waterproof adhesive layer is installed between the bridge deck pavement underlayer and surface layer, enhancing the bridge's waterproof performance, reducing damage to the bridge structure caused by water seepage, and further extending the bridge's service life.
