Lava, underground river, the fault fracture zone, the coal-bearing strata and gas, Highland stress ... these complex geological problems are "stumbling block" construction projects. Most terrible countless high-pressure water-rich, easily occur Mud Outburst large melting chamber and the underground river, the tunnel construction is extremely difficult, time should beware of the threat of Mud Outburst slightest mistake will suffer disaster.

Wanzhou Railway Construction Headquarters, and more than 20 construction units to rely on scientific and technological progress and independent innovation, construction, and management to achieve a number of "first": Worldwide tunnel risk classification for the first time, for the first time to regulate the advanced geological prediction, pioneered complex karst tunnel Mud Outburst fire alarm system, special design, pioneered adverse strata grouting management, the first use of high pressure water-filled karst release buck patented technology ......
red deer Qing tunnel, the head of a 600,000 m3 of the poly water soluble cavity, known as the gushing water tunnel in the world's history of railway construction, construction occurred 14 large water inrush disaster.
