Protection of steel transmission type erosion control dam engineering

摘要

(57) [summary] [purpose] in steel transmission type Sabo dam, that the anti-rust treatment of the surface rust effect is no longer exposed easily damage to steel pipe surface by falling earth gravel collide without, steel pipe of the portion immersed in high acidity water I is to ensure that there is no possibility to decrease significantly durability and corrosion. [Configuration] The present invention is, until near the point where immersed in the steel transmission type Sabo dam at least falling soil gravel collide or water of steel that form, enclosed in protective material covering the outer peripheral surface of an elastic body made of covering material We realized the abrasion, impact and chemical resistance by it.
