Abstract
Изобретение относитс к строительству и касаетс способов защиты фундаментов от нормальных сил морозного пучени . Цель изобретени - повышение эффективности способа. Это достигаетс за счет укладки на дно и стенки скважины 2 полиэтиленовой пленки 3, после чего скважину заполн ют уплотненным грунтом 6 обратной засыпки. Концы пленки закрепл ют в верхней части фундамента 5. 1 ил.The invention relates to construction and concerns methods for protecting foundations from normal frost heave forces. The purpose of the invention is to increase the efficiency of the method. This is achieved by laying the polyethylene film 3 on the bottom and walls of the well 2, after which the well is filled with compacted backfill soil 6. The ends of the film are fixed in the upper part of the foundation 5. 1 sludge.

Изобретение относитс к строительству и касаетс способов защиты фундаментов от нормальных сил морозного пучени ,The invention relates to the construction and relates to methods of protecting the foundations from the normal forces of the frost heave,
Целью изобретени вл етс повЫ шение эффективности способа.The aim of the invention is to increase the efficiency of the method.
На чертеже изображен фундамент, защищаемый предлагаемым способом, поперечный разрез.The drawing shows the foundation protected by the proposed method, the cross-section.
Защита фундаментов от нормальных сил морозного пучени осуществл етс следующим образом.The protection of foundations against normal frost heel forces is carried out as follows.
Открывают шурф или пробуривают до нижней границы сезонного промер- зани - оттаивани 1 скважину 2. Закладывают полиэтиленовую пленку 3 так, чтобы она выстилала дно и стенки скважины, а ее кра вывод т на поверхность 4 вплотную к фундамен- ту 5. Затем на выложенное пленкой дно скважины укладывают и послойно уплотн ют грунт 6 обратной засыпки, на который устанавливают фундамент. Концы пленки в верхней части фунда- мента закрепл ют ст жками 7 или другими приспособлени ми.The hole is opened or drilled to the lower boundary of the seasonal depth by defrosting 1 well 2. Polyethylene film 3 is laid so that it lines the bottom and walls of the well, and its edge is brought to the surface 4 close to the foundation 5. Then the bottom of the well is laid and layer-by-layer compaction of the backfill soil 6 on which the foundation is laid. The ends of the film in the upper part of the foundation are secured with straps 7 or other devices.
Таким образом, сплощной слой полиэтиленовой пленки, выстилающей полость скважины, выполн ет двеThus, the flat layer of the polyethylene film lining the cavity of the well performs two
функции: полностью устран ет попадание извне воды и мелкозема под подошву фундамента и таким образом предохран ет грунт, наход щийс под подошвой, от пучени , а фундамент - от вредного воздействи нормальных сил пучени и снимает касательные силы пучени за счет раст жени пленки и проскальзьшани пучащегос грун- та по контакту с пленкой,functions: completely eliminates the ingress of water and fine earth from outside under the base of the foundation and thus protects the soil under the sole from heaving, and the foundation from the harmful effects of normal heaving forces and relieves the shearing force of the film by stretching the film and slipping soil on contact with the film,
