INCREASE OF DURABILITY OF FERRO-CONCRETE WATER-ALLOCATING COLLECTORS
Are carried out researches on studying biological corrosion of ferro-concrete, as well as its properties and destroying influence on physicomechanical and operation-technical properties of ferro-concrete are reflected. Positive and negative qualities of ferro-concrete designs for their use in water removal are resulted. The indispensability of studying and overcoming of the obstacles limiting introduction of actions of secondary protection of water-allocating collectors from ferro-concrete is revealed. Also dominating obstacles are certain.Work of the scientists who were deal with problems biological corrosion, on last 15 years is analyzed.The algorithm of course of reaction is shown, the diagram of destruction сводовой parts of ferro-concrete pipes because of biogenic hydrosulphuric corrosion also is resulted. Increase of durability of water-allocating collectors probably as due to maximal use of own possibilities of concrete, such as water resistance, and applying ways of secondary protection.
