The weight of dirt is serious business and the force it provides should not be underestimated. Depending on the moisture content, soil can weigh around 2,000 pounds per cubic yard. Many construction workers die each year from trench collapses due to improper shoring and benching techniques, but weight and force calculations are also extremely important in the design and construction of retaining walls.
Proper retaining walls are expensive to build, which is a big reason many have failed throughout the country. Soil type, wall thickness, water drainage, and tie back reinforcements are major factors in the design of retaining walls, so just throwing some large rocks against some dirt won’t always do the trick.
In the video below, uploaded to Youtube by Today’s News, you’ll see the collapse of a large retaining wall in Turkey, approximately 100 feet in height, crumble under the weight of the soil it’s attempting to shore. Oddly, several people at the bottom of the pit seem to be aware of the issue, as they can be seen pointing cameras at the wall. As it collapses, they slowly move away, narrowly escaping being buried. The bottom of the retaining wall is the last place I’d want to be if I knew there were issues.
Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
Look, you could mobilize on site the boring old way by loading your heavy equipment on the bed of a trailer and driving it to site, or you could take a note from the Bravo Company of the 37th Engineer Battalion of the United States and spice things up a bit.
“World’s Largest” is definitely a sought after goal, especially in the construction industry. Sarens, a crane rental, heavy lifting, and engineered transport company in Belgium, has recently released a supersized crane that is being regarded as the largest crane in the world, by both size and lifting capacity.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
