Abstract
Сущность изобретени : дл защиты фундамента от пучени в грунте разрабатывают продольные и поперечные щели и заполн ют их непучинистым материалом. Затем на поверхности грунта устраивают непучинистую подушку. Щели выполн ют с шагом, равным 1/4 ширины фундамента, и глубиной не менее 1/2 глубины сезонного промерзани грунта. 2 ил.SUMMARY OF THE INVENTION: To protect the foundation from heaving in the ground, longitudinal and transverse slots are developed and filled with non-porous material. Then, a non-porous pillow is made on the surface of the soil. The slots are made with a step equal to 1/4 of the foundation width and a depth of at least 1/2 of the depth of seasonal freezing of the soil. 2 ill.
Description
Изобретение относитс к строительству , а именно к защите фундаментов от пучени грунта.The invention relates to construction, and in particular to the protection of foundations from soil heaving.
Известен способ возведейи фундамента в виде железобетонной плиты, уложенной на гравийно-песчаную подушку.There is a method of erecting a foundation in the form of a reinforced concrete slab laid on a gravel-sand cushion.
Также известен способ защиты фундамента , включающий выполнение непучини- стой подушки под фундаментом и вертикальных полостей в грунте основани с последующим заполнением полостей непучинистым материаломAlso known is a method of protecting the foundation, including the implementation of non-porous cushions under the foundation and vertical cavities in the soil of the base, followed by filling the cavities with non-porous material
Недостатком этих способов вл етс недостаточна эффективность снижени силы пучени при большой глубине сезонного промерзани .The disadvantage of these methods is the lack of effectiveness in reducing heaving forces with a large depth of seasonal freezing.
Целью изобретени вл етс повышение эффективности защиты фундамента от морозного пучени грунтаThe aim of the invention is to increase the effectiveness of protecting the foundation from frost heaving of the soil
На фиг.1 изображен план основани фундамента; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows a plan of the foundation base; figure 2 is a section aa in figure 1.
Способ защиты фундамента от пучени грунта включает нарузку продольных 1 и поперчных 2 полостей в виде щелей, заполнение полостей гравийно-песчаным грунтом 4, затем выполн ют гравийно-песчаную подготовку и укладывают железобетонный фундамент 3 с шагом полостей в виде взаимно пересекающихс продольных 1 и поперечных 2 щелей с шагом 1/3-1/4 ширины фундамента 3 и глубиной не менее 1 /2 глубины сезонного промерзани грунта основани .A method of protecting the foundation from soil heaving involves loading longitudinal 1 and transverse 2 cavities in the form of gaps, filling the cavities with gravel and sand soil 4, then performing gravel and sand preparation and laying the reinforced concrete foundation 3 with a cavity pitch in the form of mutually intersecting longitudinal 1 and transverse 2 slots with a pitch of 1 / 3-1 / 4 of the width of the foundation 3 and a depth of at least 1/2 of the depth of seasonal freezing of the soil of the base.
