Lots Of Poking But No Answers On What’s Blocking 99 Tunnel Drill
The Seattle Times ^ | December 30, 2013 | Mike Lindblom

Posted on 01/02/2014 6:59:23 PM PST by Windflier

A half-dozen probes have not hit any huge object in front of Bertha, adding to the mystery of what’s blocking the stalled Highway 99 tunnel machine.

From the article:

"Workers have poked the soil in six locations in front of the stranded tunneling machine Bertha, but their probes haven’t bumped into any huge obstructions yet, a senior engineer said Monday.

Those results increase the mystery over what might be blocking the world’s biggest tunnel machine. Project leaders initially speculated that an unusually wide boulder, deposited by ancient glaciers, might be in the way.

Progress on the Highway 99 tube has stalled since Dec. 6, when the rotary cutting blades of the 54.3-foot-diameter drill spun without scouring much sediment between Pioneer Square and Elliott Bay.

The probe holes are being drilled 110 feet deep and spaced five feet apart, from east to west. A hole-digging rig was out Monday morning to take another poke, and more test holes will be drilled Tuesday.

“We’re not hitting anything unexpected,” said Dave Sowers, tunnel-engineering manager for the state Department of Transportation. If a school-bus-size boulder were there, he said, the probes should strike it.

Meanwhile, contractor team Seattle Tunnel Partners intends to send workers into Bertha’s flooded front end Thursday to inspect for the blockage through gaps in the cutting head, Sowers said. Many crew members were gone on holiday, so contractors chose to wait for their return before starting the inspection, he said.

The tunnel team hopes to remove enough groundwater so the inspection can be done at normal air pressure. Ten wells have been installed around the buried machine to extract the silty water that permeates this stretch of the route."

Pretty sure that's one of the first things they checked for. Unlike Obama drones, these folks are actually competent and professional at their jobs.

At the link they said they are taking this time to replace many of the dull cutters. I'm guessing it is more than just that though. Pretty embarrassing if that's all it ends up being. (Or like I posted on another thread “Hey - who left the emergency brake on!?”)

Doubt it. This delay has cost oodles more than if they'd just kept running. Plus, the contractor will get caught in the biggest lie since Obamacare, if they don't come up with a plausible, documented reason for this stoppage.

http://seattletimes.com/html/localnews/2022578298_berthaessaysxml.html

One of the local school’s 5th graders are trying to figure it out, and looking at the history of the area. Lots of guesses of trains, etc. that are remnants of old Seattle that ARE buried under the existing surface. But Bertha is 80 feet deep or so, and the old Seattle surface is only down 20 feet or so IIRC. Perhaps to 50 feet in the old bay, but I think Bertha is inland from that now. I think it is in 15,000 year old glacial material.

On the 6-borings spaced 5-feet apart though, that only covers 25 feet wide. Bertha is 58-feet diameter, so seems they have left plenty of room to still miss something big.

Oh yeah. I've seen videos of that facility before. It's not secret. There are no guards. It's just an old salt mine that's been turned into the world's largest warehouse.

Leave it to Jesse Ventura to set up the video to make like he's some kind of spy, getting into a secret government complex. What a hoot.
