816 underground nuclear power plant

In 1967, a mysterious special forces unit secretly entered the deep mountains of Fuling, Chongqing, and excavated an underground nuclear power plant. The Chongqing 816 underground nuclear power plant, built to serve the production of atomic bombs, is the "world's first artificial tunnel" with a total investment of 740 million yuan. The project started in 1967 and was initially excavated and drilled by engineering soldiers. After 1975, the 816 factory construction team carried out the construction of the factory building, with a total manpower of over 60000 people. Due to changes in the international situation and the need for national economic strategic adjustments, the project was suspended in 1984. Decrypted in April 2002. In 2010, the "816 Project" was partially opened to tourists as a scenic spot for the first time. Subsequently, in order to further improve and upgrade the facilities of the scenic area, the Fuling District Government carried out a one-year fully enclosed construction of the "816 Project" in 2015. On September 25, 2016, after a year of rest, the doors reopened to welcome guests.

The total construction area of the 816 underground nuclear project is 104000 square meters, with 18 large caverns, including 130 roads, pilot tunnels, branch tunnels, tunnels, and vertical shafts. The axial length of all caverns exceeds 20 kilometers, with the largest cavern reaching a height of 79.6 meters. The excavation span of the side walls is 25.2 meters, the arch span is 31.2 meters, and the area is 13000 square meters. The engineering design of "there are buildings in the cave, holes in the buildings, and rivers in the cave" won the collective award of the National Science and Technology Conference in 1978.

It is shocking that such a huge and complex project, all manually excavated, can pave a city wall from Chongqing to Tiananmen with the excavated stones. Moreover, it is so sturdy that it can withstand earthquakes of magnitude 8 and even withstand hydrogen bomb attacks, making it a world miracle.

The 400 meter long tunnel at the entrance quickly throws you into another world, causing a slight sense of fear in your heart. By the time you enter the first chamber, you haven't had a chance to see clearly. A "space" as large as a commercial building stands up, exceeding any expectations in your mind.

The 816 nuclear project has a building in the cave and a hole in the building, with a total of 18 floors and each floor reaching 6 meters. It is like a giant building embedded in the mountain, with a structure that is beyond imagination. According to different functional zones, the space size of each floor varies. Some are as small as offices or parking lots, some are so large that you need to look up 90 degrees to see the top, and some can accommodate a plane, so large that it instantly "shrinks" people.

Tourists are almost walking up and down a maze like city. The largest cavern inside is the main building of the reactor hall, which is equivalent to a building over 20 stories high.

The "bottom" of the nuclear reactor is located on the 8th floor of the tunnel, with an internal structure resembling a huge machine. The top of the hall is covered with steel ventilation holes, and the brackets and space cores inside the holes are still intact. Inside, there is also heavy crystal sand that was once transported. The mixer above is parked there, seemingly ready to operate.

In the main control room, the densely packed keyboards and instruments look intact, and you can't help but imagine the scene of scientists busy here back then.

And slogans such as' Foolish Old Man Moves Mountains, Man Conquers Heaven 'written on the wall seem to remind you of the era in which the 816 nuclear project was located and the people's fighting spirit back then.
