The Hanzhong Tiankeng Group is so precious that it is hard to imagine that their discovery was originally related to a photo of Zhang Weixing.
From April 2065438 to April 2006, Shaanxi Provincial Department of Land and Resources organized and implemented the investigation of geological relics in the whole province, and the staff of Shaanxi Geological Survey Center went to all parts of the province to carry out related work. The team in charge of Junliang Zhang conducted an investigation in Shanyang County and Zhen 'an County in the south of Shaanxi Province.
One day in early May, my colleague sent a photo to Junliang Zhang, director of the Institute of Remote Sensing of Shaanxi Geodetic Center, with his mobile phone, saying that there was a suspected sinkhole in the south of Shaanxi. Through remote sensing interpretation and analysis, drone aerial photography and other means. , Junliang Zhang initially determined the specific direction and size of more than 10 sinkholes.
"Find it and learn about it." Seeing is believing, and field investigation is necessary. In July, Junliang Zhang, Huang Jianjun, Ning Shejiao, Li Xinlin and Li Yichao, four senior engineers, formed the first expedition team of Hanzhong Tiankeng Group and began on-the-spot investigation. With the advancement of the Hanzhong Tiankeng Group project, more and more technicians are involved in the project. Shaanxi Geological Survey Center specially deployed more than a dozen team members to enrich the investigation team.
Hanzhong Tiankeng Group is located in the deep part of Qinba Mountain area, so it is difficult to investigate. The mountain road is difficult to walk, so they try to speed up. Team members are often bitten by bamboo stubble, wild thorns and poisonous insects ... communication in the mountains is very backward. In order to take care of the front and back, the team members communicate with each other by whistling codes-everyone hangs a whistle around his neck and communicates by blowing out different tones.
Walking in the mountains, you need to lighten the load. The members of the investigation team take as little things as possible, including food, every time they travel. The players will eat as much as possible before leaving, and each will bring two or three chocolates to satisfy their hunger. Many players suffer from gastrointestinal diseases due to long-term irregular diet. On the way, colds and fever often occur.
On February 20 16, Yuan Daoxian, an academician of China Academy of Sciences and a domestic expert in karst geology, visited the Tiankeng Group in Hanzhong. He said: "Hanzhong Tiankeng Group is at the northernmost boundary of Tiankeng karst landform discovered in China at present, which is of great significance."
