Description
с помощью системы стержней 7 раз ной длины, снабженных тонкими перфорированными дисками 8, помещенными на поверхности и в глубине исследуемого , глинистого грунта (в различных точках его) определ ют динамику процесса набухани грунта в услови х, близких к натурным..using a system of rods of 7 different lengths, equipped with thin perforated discs 8, placed on the surface and in the depth of the studied clay soil (at different points of it), determine the dynamics of the process of soil swelling under conditions close to natural.
Перемещение стержней 7 (в результате деформации набухани экрана) фиксируетс соединеннымис ними приборами-индикаторами 6 часового типа, укрепленными на общей крестовине 5, котора опираетс на стойки 4-опор-. ной плиты 3 корпуса 1.The movement of the rods 7 (as a result of deformation of the swelling of the screen) is fixed by the 6 hour-type indicator devices connected to them, mounted on a common cross 5, which rests on 4-pillar stands. Noah plate 3 housing 1.
Величина набухани фиксируетс индикаторами с точностью 0,01 мм. По показани м приборов-индикаторов б расположенных на поверхности грунта, определ ют величину полного набухани грунта, а поразнице в перемещени х соседних по высоте перфорированных дисков 8 определ ют величину набу.хани расположенного между ними сло грунта.The amount of swelling is fixed by indicators with an accuracy of 0.01 mm. Based on the indications of the indicator devices b located on the ground surface, the magnitude of the total swelling of the ground is determined, and the difference in displacements of the perforated disks 8 adjacent in height determine the magnitude of the ground layer located between them.
Полученные при помощи предлагаемого устройства данные обеспечивгиот возможность точной и надежной оценки пористости, а, следовательно, и противофильтрационны 4 свойств грунтовых экранов в процессе его эксплуатацииObtained with the help of the proposed device data provide the ability to accurately and reliably estimate porosity, and, consequently, impervious 4 properties of soil screens during its operation
