白鹤梁水下保护工程平压净水系统研究与实践

Research and practice of water pressure balance and purification system in underwater protection works of White Crane Ridge Inscription

三峡库区的白鹤梁水下题刻保护工程采用"无压容器"的概念建造,实现该原理的关键设备为平压净水系统。通过选择廊道输水方式,并设计合理的水压平衡程序、充水置换程序、封闭循环程序等,实现了保护体内外水压差基本为零,且水的浊度始终达标。该系统已安全运行5 a,从而证明前期的设计思路、方法及模拟试验成果均是可行和可靠的。

The concept of ＂non-pressure vessel＂ was adopted to build the underwater protection works of White Crane Ridge Inscription, and the water pressure balance and purification system is a key equipment. For realizing balance of water pressure in the protection works and maintaining of water clear, a corridor water transferring solution is adopted, and several procedures are designed, including pressure balance procedure, water filling and replacement procedure, closed cycle procedure, et al. The system has been operated safely for 5 years, so it verifies the correctness and reliability of the previous design ideas, methodology as well as simulation tests.
