Construction time of Type 321 Bailey bridge in military operations
The construction time of Type 321 Bailey bridge in military operations varies depending on the span, complexity and proficiency of the bridge operators. Here are some specific cases and data:
1. **Actual case**
- On July 6, 2016, the bridge squadron of the Sixth Brigade of the Armed Police Traffic Brigade built a Bailey bridge in Dingjiazhai Village, Yanjiahe Town, Macheng City to rescue more than 800 villagers trapped in Yejia Village on the opposite bank. The bridge is nearly 200 meters long. One of the damaged and collapsed parts is close to the embankment abutment of Yanjiahe Town, with a length of more than 30 meters; the other is located in the middle of the bridge, close to Yejia Village, with a length of about 40 meters. The officers and soldiers of the Armed Police Traffic Force worked continuously day and night, and finally completed the construction of the bridge in 18 hours and 35 minutes.
- In November 2015 and September 2016, the Lishui Highway Administration Bureau conducted emergency erection and dismantling drills for the 321-type Bailey bridge in response to landslide geological disasters. In one drill, the rescue team successfully erected a 321-type Bailey bridge with a single span of 12 meters and a width of 3.75 meters in just one and a half hours.
2. **Theoretical data**
- According to the user manual of the 321-type Bailey bridge, the assembly and laying of the bridge are very convenient and the bridge can be built in a short time.
- In general, the construction time of the 321-type Bailey bridge depends on the span and complexity of the bridge. For a bridge with a single span of about 30 meters, skilled operators can usually complete the construction within 6 to 12 hours.
Summary
The construction time of the Type 321 Bailey Bridge in military operations usually ranges from a few hours to a day, depending on the span, complexity and proficiency of the bridge operators. Its rapid construction and disassembly features make it an ideal choice for emergency situations.
