What aspects should be paid attention to during the installation and disassembly of Bailey Bridge?

Bailey bridge is widely used in the world, the most popular bridge, it has the characteristics of simple structure, convenient transportation, rapid erection, easy decomposition. With large carrying capacity at the same time, the structure, strong rigidity, advantages of long fatigue life. It can be composed of various types of temporary Bridges, emergency Bridges and fixed Bridges according to the actual needs of different spans, with fewer components, light weight and low cost.

The installation method of a Bailey frame

First, the bailey frame is assembled on the ground according to the number of designed pieces, and grouped and connected. Mark the positions of each group of Bailey frames with paint according to the designed spacing on the I-beam. Then, 20t crane is used to lift the connected Bailey frame into place in order from the middle to the two sides, and the Bailey frame is fixed on the beam with homemade U-shaped card.

Unloading scheme of Bailey frame and matters needing attention

The unloading scheme is similar to the loading scheme, but is the reverse process of the loading program. The unloading process is also divided into two stages. To evenly unloaded in turn, to prevent the impact of sudden release of load, and properly placed heavy objects so as not to affect the normal construction. During unloading, each stage shall be observed and recorded before unloading to the next level of load, and the elastic recovery of the Bailey frame shall be measured and recorded. All measurement records should be reported to the trial steering group on the same day, and abnormal problems found on site should be reported in time.

The assembly of Bailey plate is made use of the force of Bailey plate. Bailey truss not only has the characteristics of simple structure, fast and light, strong adaptability, good systematic comparison of combined structure, strong interchangeability, easy assembly, but also its span and column height can be adjusted to adapt to different work sites. It is widely used in highway, railway, municipal, construction, water conservancy and other construction projects, bridge construction precast yard lifting and transporting precast members, pier side girder and other on-site construction operations. Mainly used for cast-in-place and construction of bridge. Cost-effective.
