00:00This is a moment when the bridge is blasted.

00:05Under the slow motion of the high-speed camera, you can see the whole process of the blasting

00:10network extending forward, just like a science fiction blockbuster.

00:15Bridge blasting is an important means to demolish those bridges that have been judged to be

00:19micro-bridges for a long time, or to rebuild the bridges as the traffic pressure increases.

00:26Although the blasting process only takes a few seconds, the design of the plan, the

00:31location of thousands of blast holes, the depth of buried charges, and the amount of

00:37buried charges must be calculated many times.

00:40A series of constructions such as drilling, burying charges, and connecting networks must

00:45be very precise and cautious.

00:47The bridge after the blasting makes full use of the disintegration and crushing effect

00:52of the bridge under its own weight after the instability, which can break most of

00:56the bridge panels and greatly reduce the time of mechanical processing.

01:00The bridge blasting sites in many places abroad will also attract countless people to watch.

01:06They set up cameras and wait for hours just to watch this shocking scene.

01:11However, not all bridges are suitable for demolition by blasting.

01:16In some areas and bridge shapes, when demolishing most bridge shapes manually, you only need

01:22to follow the order of bridge construction and do it in reverse.
