Twenty-five years directed the works of the Sagrada Familia. Jordi Bonet walks between scaffolding and construction materials proud to be one of the followers of one of the most emblematic works of Antoni Gaudi and Barcelona. But the works of the TGV that take place right next to the building frustrating if the Ministry of Public Works does not change the route of the high speed train passing through the center of Barcelona veteran architect considered unable to confirm the safety of building.
Well, underneath the building that weighs more than the city come to spend three tunnels. In addition, two underground tunnels go through a strip of land called the Quaternary, a good ground. All houses in the Eixample, some more than a century, holds on this earth and never have sunk. But the TGV tunnel built more depth below sea level, 12 volt food warmer the so-called tertiary, and there is no water.
Geology 12 volt food warmer of Bacelona: this color scheme indicates taronge layer of Quaternary some tough clay. A good land on which sits the city of Barcelona. The bottom 12 volt food warmer layer is yellowish tones oldest 12 volt food warmer Tertiary. Do not compact and hard as clay and tuff but disintegrated. 12 volt food warmer Made up of sand, gravel, some clay, water flooded into circulation at the rate of one meter a day towards 12 volt food warmer the sea. The water is not stagnant in our subsoil is moving 12 volt food warmer and that makes it even more dangerous. Geology unforgiving. No need much imagination to realize that if it removes a layer tuff that will crack the hard layer above. And 2nd, it is obvious that you should not put obstacles in the water circulation so that the behavior is totally unexpected. In the Mediterranean coast we have a lot of experience with sudden 12 volt food warmer downpours. More recently, remember that the streams which crosses the entrance of the AVE Sants they move "up" (finer sand particles) which bent a wall for lack of grounds and had to interrupt train traffic for 50 days in october-November 2008.

Yes. In fact, with the foundation of the Holy Family, we have never wanted to spend in the water table, where there is groundwater, because that is the gamble. The water is very dangerous.

In red are the pilots of the screen "protector" section viewed, and the AVE tunnel on the same scale. The parts already built the temple are shaded in green, gray and still do.
From the Sierra Collserola between the river Llobregat and Besos River down a thirty torrents. Specifically, there go two streams. And the water still continues to come down from the mountains, although the level changes depending on whether it rains or there is a drought.
Plano general streams of Barcelona with the planned tunnel for the AVE, detail plans and expanding the area of the Sagrada Familia. The old stream called "Delemus" now paved under the street to play the Sardinia island occupied by the temple. Click on the two images to see them full-screen. The route chosen by the Ministry of Development, however, is shorter.
Yes, this is true, the straight line that connects the station Sagrera and Sants Station is Carrer de Mallorca. But long before they wanted to do this tunnel had already Sagrada Familia. 12 volt food warmer
Click on the image to see it larger. The screen is a lot of holes, 1.5 meters in diameter, positioned on each cabbage 50 centimeters. It is a wall. If not deprive the water go down generating a hurry. And if the water runs faster s'obtura and then drags fine sands. This could cause a drop of our foundations. A large recklessness!
Diagram showing the pilots of the screen "protector" of the foundations of the Sagrada Familia passage 12 volt food warmer of the TBM. In the scheme are well separated, but between them there are only pilot 50 cm (theoretical, because during the construction will likely 12 volt food warmer be a lot thicker and therefore space for the passage of groundwater more small. Therefore pilots make a "dam effect").
The tunnel passes 75 cm screen and it becomes a transmitter of vibrations from trains. We can protect vibrations but correct wavelengths. In this sense it would be catastrophic to the vibration wavelength here came into line with a wavelength of the columns of the temple. So sink bridges ie
