Изобретение может быть использовано при производстве бетонных, железобетонных , асбестоцементных и других труб, изготовл емых из материалов на основе минеральных в жущихThe invention can be used in the manufacture of concrete, reinforced concrete, asbestos cement and other pipes manufactured from materials based on mineral materials.
Известен способ изготовлени труб путем формовани труб из бетонной смеси с арматурой и без нее с последующим набором прочности бетона в естественных услови х или при тепловлажностной обработке 1.A known method of manufacturing pipes by molding pipes from a concrete mixture with and without reinforcement, followed by a set of concrete strength in natural conditions or during heat and moisture treatment 1.
Этот способ не обеспечивает высокое качество труб и их водонепроницаемость .This method does not provide high quality pipes and their water resistance.
Наиболее близким по технической сущности к предлагаемому способу вл етс способ получени бетонных изделий , заключающийс в формовании, термообработке и пропитке изделий в водном насыщенном растворе фосфата аммони в течение 2-5 мин 2.The closest to the technical essence of the proposed method is a method of producing concrete products, which consists in molding, heat treatment and impregnation of products in an aqueous saturated solution of ammonium phosphate for 2-5 minutes 2.
Однако известный способ не обеспечивает -сачества труб, необходимого дл работы в напорных трубопроводах, так как в результате обработки лишь в поверхностном слое бетона образуетс фосфат кальци , кольматирующий поры и капилл ры.However, the known method does not provide the quality of pipes necessary for operation in pressure pipelines, since as a result of processing only calcium phosphate, clogging pores and capillaries are formed in the surface layer of concrete.
Цель изобретени - повышение водонепроницаемости труб из бетона иThe purpose of the invention is to increase the water resistance of pipes made of concrete and
железобетона при работе их в напорных трубопроводах.reinforced concrete when operating them in pressure pipelines.
Поставленна цель достигаетс тем/ что после формовани и термообработки трубы предлагаемый способом пропитывают натриевым жидким стекломс кремнеземистым модулем 2,65-3,40 и плотностью 1,3 6-1 ,51 г/см в течение 5-20 мин под давлением, превышающим The goal is achieved by the fact that, after forming and heat treatment, the pipes proposed by the method are impregnated with sodium liquid glass silica modulus 2.65-3.40 and density 1.3 6-1.1, 51 g / cm for 5-20 minutes under pressure exceeding
0 испытательное, но не выше давлени трещиностойкости. При изготовлении труб, характеризующихс сильно дефектной структурой, или труб, к которым предъ вл ютс специальные тре5 бовани , после обработки жидким стеклом их дополнительно обрабатывают веществом , коагулирующим или химически разлагающим натриевое жидкое стекло, инъектированное в бетон труб. Это по0 вышает долговечность пропитки таких труб и улучшает их эксплуатационные, характеристики. Дг1Я этого используют растворы вещества, выбранного .э группы, содержащей НССБ, Fe(SO4)i, 0 test, but not higher than crack pressure. In the manufacture of pipes, which are characterized by a highly defective structure, or pipes, to which special requirements are imposed, after treatment with liquid glass, they are additionally treated with a substance that coagulates or chemically decomposes sodium liquid glass injected into the concrete of the pipes. This increases the durability of the impregnation of such pipes and improves their performance characteristics. An example of this is using solutions of a substance selected from the group containing NRSS, Fe (SO4) i,
5 Ae(NOj)g, / Са(МОз)г , ZnSOt , (NH4)2. SO.; газы, содержащие СО или 50з ,5 Ae (NOj) g, / Ca (MOh) g, ZnSOt, (NH4) 2. SO .; gases containing CO or 50h,
Дл снижени в зкости натриевого жидкого стекла, увеличени глубины To reduce the viscosity of sodium liquid glass, increase the depth
