..pdfбоковую поверхность. При этом степень увеличения несущей способности у двуконусных свай значительно больше, чем у призматических.
12.ДОПОЛНИТЕЛЬНЫЕ РЕКОМЕНДАЦИИ
12.1.В сильнопучинистых грунтах для достижения более высокого уровня надежности фундаментов дополнительно рекомендуется:
– производить погружение свай методом вдавливания;
– щель вокруг головы сваи, образованную при вдавливании,
засыпать непучинистым материалом (непучинистыми грунтами I группы, песком природным и из отсевов дробления, щебнем крупностью до 40 мм, песчано-гравийной смесью, а также смесью из перечисленных материалов) для предотвращения смерзания грунта
сбоковой поверхностью сваи.
12.2.Во избежание самопризвольного заполнения щели местным сильнопучинистым грунтом и для повышения качества производства работ засыпку щели рекомендуется производить сразу после погружения сваи до погружения соседних свай.
