1800 UNDERGROUND COLUMN STABILIZING THE GROUND FOR THE NEW BRIDGE. By October this year, the Public Works BE COMPLETED.
Neuenhuntorf - In Neuenhuntorf the earth trembles. On the grass beside the old highway the heavy equipment humming in the chord. Here's just the civil engineering work is underway for the new bridge over the B 212th
"We started four weeks ago," George Pruin, Foreman says on the site. "Right now we ram with the heavy equipment displacement tubes into the ground." In the holes will be geo-textile bags, on the site as "socks" called, filled with bitumen and sand. Then the barrel of the machine is pulled. Remain underground pillars that will stabilize the soil.
The noise of the ram is deafening. They drive the eight-meter-deep tubes quickly into the ground. Then, the excavator is a funnel to the column and is the filling in the hole. This is then compressed again.
"This special column called GEC-pillars. They are better than columns of concrete, because they are flexible, as it were, a mobile system under the ground, "said Alexander Sub, site manager of the Hamburg-based company that carries out the excavation work. 1800 of these columns are required for the stability of the bridge in Neuenhuntorf. "By the end of October we're done," said Sub. However, would also later on the highway pillars are set. "This will probably be up to 50 000 units," said the foreman. According to current plans is the bypass to be completed in 2014.
