The modular footbridge has attracted much attention because of its efficient and flexible construction process. Compared with the traditional bridge construction, the advantages of the modular footbridge in the construction process are mainly reflected in the four aspects: prefabrication, transportation, installation and debugging.
1. Prefabrication stage: The prefabrication of modules in the factory is the first step of modular pedestrian bridge construction. The engineer manufactured the modules according to the design drawings, which usually include the bridge deck, supporting structure and connections, etc. The advantage of the prefabrication stage is that it can be produced in a controlled environment, ensuring the consistency and high standards of module quality. The production process in the factory reduces the complexity of the site construction, and can effectively control the construction cycle.
2. Transportation stage: The prefabricated modules are transported to the construction site by transportation tools. This stage requires precise logistics planning to ensure that the modules are not damaged during transportation and can arrive at the construction site on time. The efficiency of the transportation stage directly affects the time and cost of the whole construction, so the logistics management is a crucial link.
3. Installation stage: At the construction site, the construction of infrastructure needs to be completed first, such as pile foundation or foundation beam, which will support the weight and service load of the entire bridge. During the installation stage, the prefabricated modules are transported to the designated position one by one through the heavy equipment such as the crane. These modules are usually designed to allow for rapid docking, with precise positioning and connections. The connection and fixation between the modules require a high degree of accuracy to ensure the stability and safety of the bridge.
4. Commissioning and acceptance stage: After the installation, the final commissioning and acceptance test shall be conducted to ensure that the bridge meets the design standards and safety specifications. This stage includes checking the overall stability of the bridge, the strength of the connections, and the flatness of the bridge deck. During commissioning, some minor adjustments may be required to ensure that the bridge works properly in practical use.
In general, the construction process of the modular footbridge greatly shortens the construction time and improves the construction efficiency through the four steps of prefabrication, transportation, installation and debugging. Its flexible modular design enables the bridge to be quickly built quickly in different environments, meeting the efficient needs of modern cities for infrastructure construction. At the same time, it reduces the complexity of the site construction and the impact on the environment, providing a new solution for the rapid construction and upgrading of urban infrastructure.
