Известен способ изготавлени тонкостенных армоцементвых конструкций торкретирова нием путем увлажнени сухой цементнопесчавой смеси водой перед вы|бр(0сом ее из форсунки сжатым воздухом.The known method of making thin-walled cement-cement constructions by shotcrete by moistening the dry cement-sand mixture with water before the extraction (using its air from the nozzle with compressed air).
Дл ускорени процесса твердени смеси, снижени отходов материалов и 31апыленности р-абочего места предлагаетс способ, по которому цементнонпесчаную смесь увлажн ют гор чей водой с температурой 90-95° С. Цементно-песчаную смесь можно увлажн ть смесью горЯчей воды и пара.To speed up the process of hardening the mixture, reduce waste of materials and the dust content of the workplace, a method is proposed whereby the cement-sand mixture is moistened with hot water at a temperature of 90-95 ° C. The cement-sand mixture can be moistened with a mixture of hot water and steam.
Способ осуществл ют следующим образом. Сухую цемен1тно-песчаную смесь в сопле непосредственно перед выбросом увлажн ют го водой с температурой 90-95° С или смесью гор чей воды и пара. этого камеру увлажнени сопла соедин ют с системой питани водой, на примор с бойлерной установкой.The method is carried out as follows. The dry cement-sand mixture in the nozzle immediately before discharge is moistened with water at a temperature of 90-95 ° C or with a mixture of hot water and steam. This moistening chamber of the nozzle is connected to a water supply system, for a primer with a boiler plant.
При гор чем торкретировании качественно мен ютс услови твердени торкрет-бетона. В результате затворени гор чей водой торкрет-бетон укладывают в подогретом состо нии . Благодар этому интенсифицируетс процесс твардени бетона, особенно в ранние сроки, и соответственно сокращаетс общийWith hot gunning, the conditions for the hardening of the concrete are changing qualitatively. As a result of mixing with hot water, the shotcrete is placed in a heated state. Due to this, the process of concrete striking is intensified, especially in the early stages, and the overall
технологический цикл производственного процесса .technological cycle of the production process.
При гор чем торкретировании цементные зерна лучще смачиваютс гор чей водой, увеличиваетс кле ща способность цементного теста, и образуетс атмосфера с повышеннюй влажностью в зоне торкретировани за счет более интенсивного испарени гор чей воды и пара.With hot gunning, the cement grains are better moistened with hot water, the adhesiveness of the cement paste increases, and an atmosphere with high humidity in the shotcrete zone is formed due to more intense evaporation of hot water and steam.
Та-ким способом можно наносить на издели изол ционные и облицовочные слои.In this way, insulating and facing layers can be applied to products.
