Abstract

Изобретение относитс  к строительству и может быть использовано при подводном бетонировании с применением химических добавок - ускорителей твердени  бетона. Целью изобретени   вл етс  упрощение процесса бетонировани  и повышение качества бетонируемых конструкций. Цель достигаетс  растворением в воде котлована, в котором установлена опалубка, химических добавок - ускорителей твердени  бетона и подачей в опалубку сухой бетонной смеси.The invention relates to the construction and can be used in underwater concreting with the use of chemical additives — accelerators for the hardening of concrete. The aim of the invention is to simplify the process of concreting and improve the quality of concrete structures. The goal is achieved by dissolving in the water of the pit in which the formwork is installed, chemical additives - accelerators of concrete hardening and feeding dry concrete mix into the formwork.

Description

Изобретение относитс  к строительству и может быть использовано при подводном бетонировании с применением химических добавок - ускорителей твердени  бетона.The invention relates to the construction and can be used in underwater concreting with the use of chemical additives — accelerators for the hardening of concrete.

Целью изобретени   вл етс  упрощение процесса бетонировани  и повышение качества бетонируемых конструкций.The aim of the invention is to simplify the process of concreting and improve the quality of concrete structures.

Поставленна  цель достигаетс  тем, что вначале щебень и песок естественной влажности в необходимой пропорции перемешивают с портландцементом без добавлени  воды и химических добавок. Затем в обводненном грунтовыми водами котловане устанавливают опалубку и раствор ют химические добавки - ускорители твердени  бетона в количестве, соответствующем расчету. После этогоThis goal is achieved by the fact that, at first, crushed stone and sand of natural moisture in the required proportion are mixed with Portland cement without the addition of water and chemical additives. Then, in a pit flooded with groundwater, a formwork is installed and chemical additives, concrete accelerators, are dissolved in an amount corresponding to the calculation. Thereafter

сухую бетонную смесь загружают в заполненную водой опалубку, где она твердеет со скоростью, заданной составом и количеством химических добавок.dry concrete mix is loaded into a water-filled formwork, where it hardens at a rate given by the composition and quantity of chemical additives.
