在設計和运用水工建筑物中的压力管道、攔汚柵及閘門等金属結構时,常会遇到一个困难的問題是如何設法防止这些結構受腐蝕。虽然,在一些設計規范中,也規定了閘門面鈑在滿足結構計算强度外,可附加1.0公厘作为防蝕(?),压力鋼管在一般情况下允許附加1.0-2.0公厘的磨蝕(?),必要时还可超过2.0公厘;另外,在許多水工建筑物的运行管理办法中,亦制訂了水工金属結構应在2—4年内清扫油漆一次。但是,根据很多运行总結资料却說明,这种規定都会加大費用,而且不一定能够解决問題。如佛子嶺水庫
In the design and application of metal structures such as pressure pipes, trash traps and gates in hydraulic structures, a difficult issue often encountered is how to prevent these structures from being corroded. Although, in some design codes, it is also provided that, in addition to the calculated strength of the structure of the gate panel, an additional 1.0 mm can be added as a corrosion inhibitor (?), And the pressure tube can generally add an additional 1.0-2.0 mm of erosion (?) , If necessary more than 2.0 mm; In addition, many hydraulic structures in the operation and management approach, also developed hydraulic metal structure should be 2-4 years to clean the paint once. However, according to many operational summary data, it shows that these provisions will increase the costs and may not necessarily solve the problem. Such as Buddha Ziling reservoir
