The principle of bridge walking integral jacking is to gradually push the prefabricated steel box girder to the predetermined position of the main structure of the bridge through the propulsion force of the walking intelligent jacking hydraulic system. The hydraulic system or other power system of the walking jacking equipment provides propulsion, and at the same time, the walking intelligent jacking hydraulic system ensures the stability and safety of the walking jacking equipment and the steel box girder. Through the control room's operating table, operators can control the speed and direction of the step-up jacking equipment, making the construction process more flexible and controllable. The connection design between the walking jacking equipment and the steel box girder enables the overall jacking to effectively advance the beam section and improve the construction efficiency in bridge construction.

Bridge walking overall jacking step

Steps for bridge walking overall jacking:

1. At the starting position of the bridge, place the foot jacking equipment and the propulsion beam section on the bridge support pier.

2. Connect the foot jacking equipment with the pushing beam section and ensure that the connection is firm and sealed.

3. A support system is set up on the support pier to support the foot jacking equipment and the propulsion beam section.

4. In the control room, the operator can control the advancement of the step jacking equipment through the buttons on the console or wireless remote control.

5. The operator gradually starts the stepping jacking equipment as needed to make it start to advance.

6. The foot jacking equipment provides propulsion through the hydraulic system or other power systems to gradually push the propulsion beam section into the main structure of the bridge.

7. During the propulsion process, the support system plays the role of supporting and stabilizing the stepping jacking equipment and the propulsion beam section.

8. Operators need to closely monitor the advancement of the foot jacking equipment to ensure the smooth and safe advancement.

9. When the propulsion beam section is advanced to the target position, stop the propulsion and complete the whole propulsion process.

10. After completing the advancement, the overall jacking of the next section of the beam can be carried out, or other bridge construction work can be carried out.
