Bang: big bridge blocking boulder broken by blasting

Following a recent earthquake in China, the roads and highways had to be cleared quickly to allow emergency deliveries, as well as general transport. One key bridge was blocked by a massive boulder that had been dislodged by the quake. As the boulder was too large to move using the excavators or bulldozers that the bridge could support, a decision was made to use blasting instead to clear the path.

Following a recent earthquake in China, the roads and highways had to be cleared quickly to allow emergency deliveries, as well as general transport. One key bridge was blocked by a massive boulder that had been dislodged by the quake. As the boulder was too large to move using the excavators or bulldozers that the bridge could support, a decision was made to use blasting instead to clear the path. A drilling rig was brought into place and this machine bored a blasthole into the errant boulder, with the hole then being charged with conventional explosives. The blast then broke the boulder into pieces small enough for lighter machinery to move out of the way, allowing the bridge to be reopened to traffic.

Surly some spaces are just too small to park even the smallest car. But the city of Bristol, in southwest England, has taken no chances and has painted the double yellow ‘no parking’ lines in areas no one in their right mind could squeeze a car. Click here to see just how small the space is that authorities in Bristol have felt they need
