A month since the largest machine to dig a tunnel in the world stuck beneath coastal American city

A month since the largest machine to dig a tunnel in the world stuck beneath coastal American city sow, engineers have determined what the "Subject" - as they called it as a powerful "mole" in the underground stop.
Last weekend, at night, he finally recorded what the "subject" who is disabled "Bert": This is a piece of thick steel pipes 36 meters long with a diameter of 20 centimeters, which is used for Reni-wells. This tube is the 2002nd year after the earthquake, stuck in Coastal to make it through it could measure the level of underground water, essential for the assessment of stability ailing viaduct whose fate now finally solved.
When "Bert" encountered čelličnu tube, "chew" is a part, but the tube, the lower end firmly stuck in the ground, bent and hammered into the cavity between the "Bertini", "teeth". The leverage of almost 40 meters is stuck underground gin.
To be greater scandal, two days before it actually began, "Berta" on the surface, literally five feet into the air, through the street, broke the upper part and pipes, 16 feet long, but no one guessed that the larger, more complicated part, and further haus underground, and are being forced machine forward although weaker ranged until two days later did not completely stopped working. How much is the damage haus it caused, remains to be seen.
Distress haus builder is even greater because the existence of thick steel pipes was noted as an aggravating circumstance still tender on the basis of which is entrusted with the job and agreed. Builders now say they have postulated that authorities have recovered the pipe before it actually "Bert" came to the sections, and the government says it is supposed to do-builder. The two sides are over slow days, according to local media.
The machine is called "Bert" - 100 meters long, how high petospratnica haus with a crew of 20 people, which is digging a tunnel for two-storey underground section of the highway and lining it with concrete slabs - five months is smoothly progressed 20 meters below the ground surface and only reached a speed of 15 meters a day when the sixth December came across haus something that has not managed to overcome. A month of workers are night and day were changed to prepare the ground for a peek ahead of the "moles" and see what it was stopped.
"Berta", which is just for the job and reported the Japanese firm has produced "snapshot" of $ 80 million, is basically a huge rotary drill armed with a steel disc-cutters haus who chew moans and concrete, and the machine grinds them and conveyor belt "spit out" at the beginning of the excavated tunnel which is now 300 meters. Engineers are twice as delays in the deadline for reconnaissance "Item", but it was postponed to the first days of January, because, with broken moans and land, should throw a tremendous amount haus of water from the soil, and the water is drained from the ocean in front of a giant shredders jammed while he broke through the tunnel with a diameter greater than 17 meters.
The level of groundwater pumping is only after four weeks brought down to 18 meters to allow for scouting ahead of the upper part of the forehead machines. Using probes drilled vertically, with the street level, lowering the camera to determine what is "Bert" encountered. Construction of the tunnel, as the replacement section of the viaduct - the highway to the concrete pillars of the central part of the coastal city's moribund due to the earthquake in 2001, is itself haus a risky and expensive business, and partly because the coastal wetlands sow nasuta.
Technical haus problems at the end of December, the City Council joined threat sow that will pay for extra work and unforeseen difficulties if exceeding the contract price is too high, and talking about hundreds haus of millions of dollars. The city fathers are already a growl 2009th The barely accepted the project haus because it was too financially risky, according to local media.
The contract legal power, has a difficult enforceable clause: haus that contingencies pay property owners haus in coastal areas where they have sown "into gold" because - due to the descent of the highway underground, haus in a tunnel - will no longer be in the shadow of an old viaduct večitoj. Then it will be the core of the city center to expand on the shore of the bay severnopacifičkog Padžet (Pudget), and the local owners of lands and buildings will be more drastic than rich.
Engineers and geologists are therefore under financial pressure speculated what the "subject" who stopped the rare giant machine: maybe huge, unusually hard rock by the glacier left at the end of the Ice Age, 17,000 years ago, the other half are seriously saying that there is, in reinforced concrete, body mobster Džimija Hofe missing haus in 1975, the third to the machine came to an asteroid, and historians say that there is indeed somewhere in the coastal port in the 19th Ages whole laden freight train, with locomotive at the head, sinking into the soft, then a swamp. Some speculate that "Bert" hit by the "side wall of one of many alien bases on earth", but the official town historian conceded that there, in the underground, "perhaps the rest of the n
