Description
поры в грунте, расположенном в приконтактной к свае зоне, освобождаютс от воды и в них создаетс вакуум, под воздействием которого, а гидростатического давлени бетонной смеси поры в грунте заполн ютс цементным молоком, образующим вокруг скважпны 2 грунтобетонную зону 8.the pores in the soil located in the zone in contact with the pile are freed from water and a vacuum is created in them, under the influence of which, and the hydrostatic pressure of the concrete mixture, the pores in the soil are filled with cement milk forming around the well 2 a soil-concrete zone 8.
После окончани твердени бетона 5 в скважине 2 и прилегающей к ней грунтобетонной зоне производ т естественное пли пскусственное, путем подачи холодного воздуха по перфорированным трубам 4, вмораживание сван в окружающий массив мерзлого грунта.After the hardening of the concrete 5 in the well 2 and the soil-concrete zone adjacent to it, natural or natural gas is produced, by supplying cold air through perforated pipes 4, it is frozen in the surrounding array of frozen soil.
Способ обеспечивает увеличение несущей способности сваи за счет повышени равномерности прогрева п твердени бетонной смеси и обеспечени укреплени окружающего скважину грунта.The method provides an increase in the pile bearing capacity due to an increase in the uniformity of heating and hardening of the concrete mix and ensuring the strengthening of the soil surrounding the well.
