Description

Изобретение относитс к технологии изготовлени бетонных элементов и может быть использовано при изготовлении электроизолйруквдих и коррозионнйстойких бетонных конструкций, например , безизол торных траверс опор воздушных ЛИНИЙ электропередачи с внеш:ним слоем из ВЫСОКОВОЛЬТНОГО электроизол ционного цементного бетона, .The invention relates to the technology of manufacturing concrete elements and can be used in the manufacture of electrical insulations and corrosion-resistant concrete structures, for example, insulated traverse supports of overhead power transmission lines with an external layer of high-voltage electrically insulated cement concrete,.

Наиболее близким к изобретению по технической сущности и .достигаемому эффекту вл етс способ изготовлени электроизолируювдах бетонных элементов , преимущественно траверс опор ЛИНИЙ электропередач с электроиэс цион- 15 ным внешним слоем, включеоодий формовакие , сушку и пропитку 0The closest to the invention according to the technical essence and the achieved effect is a method of manufacturing electrically insulating concrete elements, mainly traversing power line supports with electrosurfing outer layer, including molding, drying and impregnation.

По известному способу из бетонной смеси обычного состава формуют траверсу на всю глубину. После достижени 20 заданной прочности отформованный эле;мент сушат до достижени бетоном требуемого уровн , 3Лект изолирующих свойств, которые стабилизируют путем пропитки внешнего сло диэлектрическими , массёши и кслтаундами.By a known method from the concrete mixture of the usual composition is formed to traverse the entire depth. After reaching the specified strength of 20, the molded element is dried until the concrete reaches the required level, 3L of insulating properties, which are stabilized by impregnating the outer layer with dielectric, mass, and X-layers.

Изготовление изделий известньЛм способом; весьма продолжительно и св зано со значительными энергозатратами так как при сушке и пропитке нагреву 30Manufacturing products limestone method; very long and is associated with significant energy consumption as during drying and impregnation of heat 30

подвергаетсй вс масса издели , хот достижение элёктроизолируюврсх свойств н их стабилизшди необходимы только во внешнем слбё материала издели .The entire mass of the product is subjected, although the achievement of electrical insulation properties and their stabilization are necessary only in the outer layer of the material of the product.

Целые изобретени вл етс повышение производительности и сокращение энергоемкости производства.The whole invention is to increase productivity and reduce the energy intensity of production.

Это достигаетс тем, что в способе изготовлени электроизолирующих бетонных элементов, преимущественно траверс опор линий электропередач с электроизол ционша высоковольтным внешним слоем, сначала формуют внешний СЛОЙ траверсы, сушат его, а затем пропитывают с одновременным или последующим формованием внутреннего сло .This is achieved by the fact that, in the method of manufacturing electrically insulating concrete elements, mainly traversing power transmission towers from an electrical insulation with a high-voltage outer layer, the outer LAYER is first molded, traverses it, then it is impregnated with the simultaneous or subsequent formation of the inner layer.

Claims

For carrying out the method, a hollow element is formed from a concrete mix of a usual composition, the wall thickness of which corresponds to the external electrical insulating concrete layer of the product, and the cavity section corresponds to the cross section of the inner layer of about 1.0 concrete. After providing the necessary strength, the molded hollow cell is dried to a given level of electrical insulating properties and impregnated, for example with petrolatum, to stabilize the electrically insulating properties. ; , 36755074,.-E ,. The cavity of an electrically-made for the perception of forces at the stockpiling element is filled with beating and transportation with a sufficient-TON mixture of the usual composition, the achievement of a 20% strength process by the concrete completes the concrete, making the concrete beam with the external strength of the proposed method. The ° ° ° electrically-ba is also the possibility of its isdasolation concrete. .5 use for the manufacture of elements Compared with the known methods with internal material, the outer layer of the product, different from the material of the outer layer, is heated when the product is dried, as well as by impregnation, which is associated with alternating cooling and heating, cooling and heating only the outer layer of the product is exposed and, as shown by the method of manufacturing electrical insolation, the results of the manufacture of prototyping concrete elements, the presses, the energy intensity of the production of socially Versa line supports electrically rotate by 30-50%. 5 transfers with electrically insulating high energy. In addition to reducing energy consumption by the use of the outer layer, including the use of the proposed method of positioning, and impregnation, it increases the output by 10-25% in order to increase productivity and underdevelopment of concrete in external-energy production, th and inner layers. This is explained by first forming the outer layer of the crossbeam, this is due to the improvement of the uelo-drying it, and then impregnated with heating and providing a possible modern or subsequent two-sided impregnation of the inner layer, reducing the heat treatment time of the outer layer, drying and information received by the serviceman, and the duration of the thermal imaging attention during the examination of the inner inner layer finishing 1.
