Повышение долговечности железобетона водоотводящих коллекторов

Повышение долговечности железобетона водоотводящих коллекторов

Abstract

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.

Проведены исследования по изучению биологической коррозии железобетона, а также отражены ее свойства и разрушающее влияние на физико-механические и эксплуатационно-технические свойства железобетона. Приведены положительные и отрицательные качества железобетонных конструкций для использования их в водоотведении. Выявлена необходимость изучения и преодоления препятствий, ограничивающих внедрение мероприятий вторичной защиты водоотводящих коллекторов из железобетона. Также определены доминирующие препятствия. Проанализирована работа ученых, занимающихся проблемами биодеструкции, за последние 15 лет. Показан алгоритм протекания реакции, также приведена схема разрушения сводовой части железобетонных труб из-за биогенной сероводородной коррозии. Повышение долговечности водоотводящих коллекторов возможно как за счет максимального использования собственных возможностей бетона, таких как водонепроницаемость, так и за счет применения способов вторичной защиты.
