Изобретение относится к способам изготовления цементногрунтовых свай в сложных гидрогеологических условиях - просадочных грунтах - по струйной технологии путем погружения буросмесителя в грунт, введения вяжущего раствора при извлечении и перемешивания его с грунтом, предусматривающий повышение несущей способности свай за счет снижения влияния отрицательного трения просадочного слоя грунта. Способ включает погружение буросмесителя в грунт глинистого раствора в два этапа - к породоразрушающему инструменту в просадочном слое и к соплам буросмесителя в непросадочном слое до расчетной глубины сваи, а цементный раствор подают через сопла буросмесителя, причем цемент подвергают мокрому домолу до перемещения его с водой в растворосмесителе. До введения в грунт, содержащих глинистых частиц в непросадочном слое более 30%, цемент домалывают с песком или иным инертным заполнителем.The invention relates to methods for manufacturing cement piles in difficult hydrogeological conditions - subsurface soils - by jet technology by immersing a drill mixer in the soil, introducing a binder solution during extraction and mixing it with the soil, providing for increasing the bearing capacity of the piles by reducing the effect of negative friction of the subsidence layer of the soil. The method involves immersing the mixer in the soil of the clay solution in two stages - to the rock-breaking tool in the settling layer and to the drill mixer nozzles in the non-substational layer to the estimated pile depth, and the cement mortar is fed through the drilling mixer nozzles, and the cement is subjected to wet grinding before moving it into the mortar mixer with water . Before introduction into the soil containing clay particles in the non-subsidence layer of more than 30%, the cement is home to sand or other inert aggregate.
