Description
Известен способ изготовлени железобетол: ,ных напорных труб, по которому бетонную смесь, перемешанную вместе с водой, загружают iB вертаькалылую форму трубы, куда предвар:ительно уст aiH а в лив а ют иродольпо нат нутую aipiMaTypy.A known method of manufacturing reinforced concrete: pressure pipes, through which the concrete mixture, mixed with water, is loaded with an iB vertical shape of the pipe, which is preceded by aiH and a myropoly tension aipiMaTypy.
Уплотпеиие осуш,ествл ют вибрированием формы и rn pionpeccoBaiH«eNr путем пагнетанн воды iB резиновую оболочку, надетую на внутреннюю Часть формы-вкладыша. Одновременно с уплот1нен ием бетанной смесн происходит нат жецние поперечиой (спиральной) арматуры , котора после затвердевани смеси и сн ти опрессовочлого давлени обжнмает бето:н трубы.The sealing was dried by vibrating the form and the rn pionpeccoBaiH ' eNr by pumping water with an iB rubber sheath worn on the inner part of the liner mold. Simultaneously with compaction of the betanous mixture, natalnye transverse (spiral) reinforcement occurs, which, after solidification of the mixture and relieving the pressure of the pressure, relieves the concrete: pipe.
Однако из1вестный способ 1не обеспечнвает получение бетона трубы достаточно -высокой плотности И П роч;ност1и, а вследствие пластнчиост1И бетш-шой смеан ие дост1игаетс иеобходимое нат жение ар.матуры.However, the well-known method does not provide concrete for a pipe with a sufficiently high density, and therefore, as a result of the plasticity of the mix, the required tension of the armature is sufficient.
Цель изобретенн - улучшение условий напр жени арматуры в процессе смеси и повышение прочйости бетола.The purpose of the invention is to improve the stress conditions of the reinforcement in the process of mixing and increase the strength of betola.
Эта цель достигаетс тем, что укладььвают сухую бетонную смесь, и одновременно с гидронреосоваиием осуществл ют увлажненис смеси ВОдой.This goal is achieved by laying down a dry concrete mix, and at the same time with hydrowetting, the mixture is moistened with water.
Суха смесь лучше уилотп етс , а вследствие повышенного трени 1между сухими частицами И арматурой носледн получает большую степень иат женл в процессе прессозан 1 .The dry mix is better, but due to the increased friction between the dry particles and the reinforcement, the ice gets a greater degree of pressure in the process of pressing 1.
Способ осуществл етс следующим образо.;.The method is carried out as follows.;.
Готов т сухую бетонную смесь (цемент, занолнитель ), состав которой подбирают из услови получени прл вибриравалпи налбольше; плотности, или то же самое - наимельше ; межзерно1вой пустотности.A dry concrete mix (cement, substitute) is prepared, the composition of which is selected from the conditions for obtaining a vibriravalpi longer; density, or the same - the least; intergranular emptiness.
После установки арматуры смесь загружаетс в форуму при работающих ла ней знбраторах . Г1о заполнении формы объем .смеси фиксируетс «1 :начинаетс процесс гидронрессозани путем нагнетаН1И воды в ладетую на вкладыш резиновую оболочку.After the reinforcement has been installed, the mixture is loaded into the forum when the toolbars are working. When filling the mold, the volume of the mixture is fixed. "1: the hydrone-pressing process begins by injecting water into a rubber casing matted to the liner.
Прессующа поверхность оболочки имеет огверстн (В виде, например, проколов. При j-aглетании воды в оболочку вода проникает о бетонную смесь.The pressing surface of the casing has an overlap (In the form, for example, of punctures. With j-aglet of water, water penetrates the casing into the concrete mix.
Последующие операцин осуществл ют 2 3вестным способом.Subsequent operations are carried out in a known manner.
Описанный способ особенно эффективел при нзготовленна труб нз цементно-иесчаного бетона .The described method is especially effective in preparing pipes for cement-sand concrete.
Предмет изобретени Subject invention
Способ изготовлени железобетонных напорных труб, заключающийс в укладке при зибрировални бетонной смеси с последующ:ил1 TMIропрессовалием ее, отличающийс тем, что. с иелью улучшени условнй напр жени арма3 туры в процессе обжати смеои и позышеиип прочпост бетона, укладывают сухую бетон4 ную амесь, и одновременно с гидропрессолапие .м о сущест-вл ют увлажа- ение смео водой.A method of manufacturing reinforced concrete pressure pipes, consisting in laying the concrete mix with the following: or 1 TMI compressed it, characterized in that. In order to improve the conditional tension of the reinforcement in the process of squeezing the mix and above the concrete dam, the dry concrete mix is laid, and at the same time as the hydraulic press, the mix is water smoothing.
