Build and dismantle speed of Type 321 Bailey Bridge
Type 321 Bailey Bridge is known for its fast build and dismantle features, which allows it to be put into use quickly in emergency situations. The following is specific build and dismantle speed information:
1. **Fast build**
Type 321 Bailey Bridge adopts modular design, and each component
can be prefabricated in the factory and then transported to the
construction site for rapid assembly. This design greatly shortens
the construction period, allowing Bailey Bridge to be built in a
short time. For example, in a flood rescue drill in Yulin City, 21
emergency rescue team members successfully erected a Type 321
Bailey Bridge with a single span of 12 meters long and 3.75 meters
wide in just one and a half hours.
2. **Fast dismantle**
The dismantling process of Type 321 Bailey Bridge is also fast. Due
to its modular design, it only needs to dismantle each component
one by one, and then load it back. This design not only improves
construction efficiency, but also reduces dependence on
professional equipment and personnel.
3. **Actual Application Cases**
In actual applications, the rapid erection and disassembly
capabilities of the 321-type Bailey Bridge make it an ideal choice
for emergency situations. For example, during the 2008 Wenchuan
earthquake, a large number of 321-type Bailey Bridges were used for
disaster relief, ensuring the forward transportation of earthquake
relief materials, the evacuation of the wounded, and the evacuation
of the masses.
Summary
Due to its rapid erection and disassembly characteristics, the
321-type Bailey Bridge can be quickly put into use in an emergency
and provide strong support for rescue work. The modular design of
this bridge not only improves construction efficiency, but also
reduces dependence on professional equipment and personnel, making
it an ideal choice for responding to various complex engineering
needs.
