How to ensure lateral stability during the installation, pre-loading, and dismantling of the Bailey panel assembly bracket

　　During the installation of the Bailey frame, before hoisting, it must be pre-assembled into a basic unit of at least two panels per truss. This Bailey frame model, when stacked in the turnover material yard with temporary supports, is less prone to sudden lateral overturning and injury, and it is also convenient for temporary stable standing after hoisting onto the column distribution beam, providing time to add temporary lateral supports on top of the column distribution beam, ensuring safety during this period of the installation process.

　　Before dismantling, the Bailey frame construction unit must prepare a special plan, which must be reviewed to ensure it is error-free, and strictly implement the plan on site, organizing lateral movement according to the plan. The Bailey frame construction unit ensures that no lateral overturning occurs during the lateral movement.

Bailey Panel Installation

　　Bailey Frame Crossbeam Installation

　　The crossbeam adopts 25 I-beam, length 5m, net span length 4M, connected with the Tony main beam as a whole with bolts, crossbeam bracket, beam spacing 2.5M, connected to each other with angle steel or standard tie rods as diagonal braces. When the beam is placed, Bailey panel construction, it is necessary to ensure that there is a crossbeam placed at the main lattice column; if the row spacing passes through the main structural column, encrypted insertion beams must be added to ensure beam spacing ≤2.5 meters.

　　Bailey Frame Temporary Bridge Towing

　　After the main beam and crossbeam are connected as a whole and the length reaches 10 meters, towing can begin. As the temporary bridge is towed forward, it is continuously extended from the rear. Install a temporary bridgehead to ensure the smooth passage of the wedge-shaped guide beam through the excavation. The other side of the winch is installed in the pit, and connected to the temporary bridge joint with a rope. Install concave rollers on top of the bridge pier, start the traction hoist from the register to tow the temporary bridge, and then adjust the position. Bailey frame construction unit

　　When designing the Bailey frame bracket, there must be sufficient lateral support frames (commonly known as "flower windows") connecting the Bailey panels laterally. Original accessories should be used as much as possible. If the spacing is not suitable for adjustment, it is necessary to process lateral flower windows yourself. Self-processed flower windows are not easy to check and calculate, so be sure to consult relevant professionals to ensure lateral stability from the structural aspect.

　　Before dismantling the Bailey frame, because the upper structure has already been formed, it cannot be lifted directly and needs to be moved laterally. Prevent hasty lifting before it is completely moved outside the horizontal projection of the structure, which may cause eccentric lifting and result in the bracket swinging freely in the air and injuring workers.
