Put the final implementation of the the Baiheliang underwater protection body, to take the “no-pressure container” program of the Chinese Academy of Engineering, GE Xiu: “pressure vessel” will be covering the White Crane Ridge, the middle; container filled with water inside and outside water pressure generally balance; top of the container to take a special steel-framed structures can withstand the impact of the 4000 tons vessel Ying Shui crash pier can withstand 10,000-ton ship hit; museum also collected through the fiber optic security system analysis of the Museum of temperature, pressure and hardness of high intensity led lamps, and other indicators to determine the security situation of the underwater protection body.
This design, neither the vandalism itself, but also make the safety of tourists, and a clear view of the inscription, and are consistent with the protection of cultural heritage “does not change the status quo does not change the principle of led high bay dependency and the natural environment.

Purification of the Yangtze River water into the shell, so that the water almost up to the standards for drinking water containers, the audience can clear viewing of the important reasons with the help of high intensity led lamps.
Inscription area is easy to assemble micro-organisms, at intervals of more than a month, professional divers will enter the underwater protection of the body, cleaning the rock surface and the viewing window. Higher in the water level in winter, the divers can only work about 40 minutes to complete a cleaning need days.
