スペインのパハレスのドンネルの高速鉄道の工事現場では、事前の水質調査もせずに大量の地下水が溢れでて2004年から始まったトンネル工事費用は当初の10億0000'0000ユーロから35億0000'0000ユーロに膨れあがる(スペインの杜撰な工事計画の典型)

Leaks of the Pajares tunnels do not stop. Tests by ADIF to waterproof tubes have been unsuccessful , as sources close to the work , and an anonymous worker has posted on Facebook Videos jets that affect AVE complex and more expensive stretch . The message data photos in February 2013. ADIF confirms that the video is taken inside the tunnels, but emphasizes that the image is in months. Development has already invested in 50 miles of the Pajares 3,000 million in 2004 compared with 1,000 initially planned .
A source who worked on the Pajares tunnels not strange content of the video: " When we went to certain areas had to go with clothing fisherman by the huge amount of water coming ." In drilling have reached peaks thousand liters per second ADIF managed to reduce to 500. The tunnel , whose cornerstone is 2004 began with little previous hydrogeological studies and the project allowed the construction inject - injected backfill behind the segments to seal and stabilize -sleazy .
Shortly after starting work TBM water started coming out . The TBM west south mouth tube " proceeded apace when the November 24, 2005 about 6:00 there was a sudden inrush of water and mud down the front of the excavation followed by two , 16 and 19 January 2006. It was the first of a series of incidents that occurred with the water since then on all fronts digging "according to a later report by ADIF .
The tunnels are drafts since 2009 , but ADIF , under Development, still looking for a solution to the leaks. The last was to ask the Eduardo Torroja Institute of CSIC materials a study on what materials could seal the tunnel. Currently there is an underground and hidden transfer from Asturias and Leon drying tunnels have dozens of springs and streams .
Last November , the Executive admitted in a parliamentary answer that the estimated cost of the work was 3.550 million , of which it has already invested 2.943 million euros. The tunnels are still opening date and the chosen option is initially open only one of the tubes .
