Abstract
Изобретение относитс к области инженерно-геологических исследований при строительстве. Цель изобретени - повышение точности определени характеристик грунта путем обеспечени условий плоской деформации. В процессе нагружени стенок скважины при прессиометрических испытани х увеличивают площадь нагружаемой поверхности грунта или поддерживают ее посто нной , соответственно увеличива или уменьша длину рабочей части камеры прес- сиометра пропорционально увеличению диаметра скважины. Прессиометр дл осуществлени способа, содержащий камеру 1 с эластичной оболочкой 3,верхним 4 и нижним 5 фланцами, снабжен двусторонним гидроцилиндром 7, щтоки 10 которого св заны с фланцами 4 и 5, и датчиком 11 дл измерени длины камеры 1. Длину камеры 1 измен ют в процессе испытаний путем подачи масла в гидроцилиндр 7, раздвигающий верхний 4 и нижний 5 фланцы, на которых закреплена эластична оболочка 3. 2 с.п. ф-лы 2 ил.The invention relates to the field of geotechnical research in construction. The purpose of the invention is to improve the accuracy of determining the characteristics of the soil by providing the conditions of plane deformation. In the process of loading the borehole walls during pressure testing, the area of the loaded soil surface increases or is kept constant, respectively, increasing or decreasing the length of the working part of the pressure meter chamber in proportion to the increase in the borehole diameter. A pressiometer for carrying out the method comprising a chamber 1 with an elastic shell 3, upper 4 and lower 5 flanges, is provided with a double-sided hydraulic cylinder 7, the rods 10 of which are connected to flanges 4 and 5, and a sensor 11 for measuring the length of chamber 1. The length of chamber 1 varies in the process of testing by supplying oil to the hydraulic cylinder 7, pushing the upper 4 and lower 5 flanges, on which the elastic sheath 3 is fixed. 2 p. f-ly 2 ill.
