Specifications
The specifications for the design of the lifting bridge present complex and specific requirements that clearly define the project's needs. Firstly, it stipulates the need for a deck width allowing the passage of 4 lanes of vehicles and 2 pedestrian lanes, while maintaining a total length of 150 meters. This requirement aims to minimize disruption to maritime and river traffic in nearby cities. The most significant constraint is to allow the passage of a 50-meter-wide container ship at water level, requiring a considerable clearance height, while considering a draft of 16 meters. The safety factor of 10 reflects the importance of bridge safety. Additionally, the bridge must be able to handle simultaneously 10 trucks of 44 tonnes per lane and an exceptional convoy of 20 meters and 72 tonnes without disrupting light vehicle traffic. Finally, the fast opening and closing time of less than 3 minutes emphasizes the required operational efficiency. Analyzing these specifications, it is clear that the challenge is to design a robust structure, efficient opening mechanics, and comply with rigorous safety standards, while seeking original solutions to meet these complex requirements.
Type of Bridge
We have chosen a lifting bridge with a removable central section for a specific project, providing an ingenious solution for areas with intense river traffic. This type of bridge minimizes interruptions to road and rail traffic by meeting the requirements of river navigation. The versatility of the bridge, with its two 75-meter parts and a removable 25-meter central section, allows smooth passage for boats. Suited for dense urban areas, this bridge offers a reduced ground footprint and can be aesthetically designed. In summary, our choice ensures smooth and safe traffic, while minimizing disruptions for road users.
Modeling
The design of the lifting bridge involved thorough modeling to ensure its strength and functionality. Precise analysis of forces and constraints, especially under maximum weight, ensured that the bridge could support these loads without compromising safety or undergoing significant deformations. The sizing of the lifting system was carefully calculated to ensure its efficiency in accordance with the specifications. Structural innovation was integrated with two 75-meter bridge parts and a removable 25-meter central section, allowing the bridge to open and close smoothly for boat passage while maintaining a strong and secure structure when closed. In summary, bridge modeling combined precise calculations and innovative design to create a structure that meets high standards of efficiency and safety, especially for ship passage.
Model
The creation of a model for our bridge project is crucial, offering major advantages in the design and validation process. Firstly, it allows a concrete visualization of the exact dimensions and proportions of the bridge on a reduced scale, facilitating understanding of its final appearance and visual impact on the environment. The model is also essential for testing and validating the opening mechanism, especially for a lifting bridge. This allows us to check the efficiency of the lifting system, its ability to support the weight of the bridge, and its compliance with the time constraints of the specifications. Furthermore, the model becomes a valuable communication tool with project stakeholders, facilitating decision-making and consensus on bridge design. In summary, creating this model helps ensure that our design meets the requirements of the specifications, offering a concrete representation of the future structure and playing a crucial role in the overall success of the project.
Financial
As part of our lifting bridge design project, the financial study is of paramount importance to assess economic viability. Estimated costs, such as labor (€1,300,000), deck (€6,000,000), and motors (€240,000), are key elements of this analysis. This study will determine the availability and adequacy of the necessary funding. It assesses our ability to cover initial costs, including other potential expenses. Additionally, it provides a realistic assessment of the long-term operating costs of the lifting bridge. In summary, this financial study helps evaluate the economic feasibility of the project, anticipate costs, plan the budget, estimate, and communicate transparently to ensure the long-term success of our enterprise.
