Micropile project in Northern Baltimore County

Our friends at Deep Excavation posted about an interesting micropile case study in Northern Baltimore County for a bridge replacement project. The project consisted of 38 Micro Piles; 7” OD X 38 ft. deep including a 7 ft. rock socket, installed on a 3/1 batter, load tested to 272,000 lbs. What caught my attention is the down the hole hammer system used for installing the micropiles. The system uses a ring bit to install the casing and allow the drill string to continue beneath the bedrock elevation to construct the rock sockets.

A 1-Minute 'Rock Avalanche' 4,800 Years Ago In Zion National Park
GeoNews - Geologic Hazards
Written by Randy Post   
Tuesday, 14 June 2016 00:04

Imagine the scene 4,800 years ago when a rock avalanche nearly 2 km long buried much of the Zion Valley in a matter of 90 seconds, creating a dam on the Virgin River that flooded essentially the entire floor of the canyon that millions of visitors enjoy every year. The researchers that analyzed this event are in the Geohazards group of the University of Utah led by Dr. Jeff Moore. Dr. Moore happens to be an old classmate of mine from the geological engineering program at the University of Arizona. I didn't dig up the publication where this Zion Canyon research was written before it went viral, but there are some great figures posted on his website and I'm sure you can click around and find the citation if you are interested.

Crowds celebrate the opening of the Gotthard Base Tunnel

The Swiss and many other European dignitaries celebrated the opening of the World's longest and deepest tunnel last week, the Gotthard Base Tunnel, after 17 years of construction. The tunnel beneath the Swiss Alps is 57-kilometers long (35-miles long) reaching a depth of 2,300 meters (7,545 feet, almost 1.5 miles). The tunnel will create a high-speed rail link between northern and southern Europe. Trains will travel the tunnel, which runs between the towns of Erstfeld in the north and Bodio in the south, in only 20 minutes, reaching speeds of up to 250 kilometers an hour (155 mph), according to CNN.
