Изобретение относитс к устройствам ДЛ1Я определени прочностных характер«сти.к грунта, в частности в услови х трехосного сжати в заВИси.моети от параметров динамической нагрузки.The invention relates to devices for determining the strength character of the type of soil, in particular, under the conditions of a three-axis compression in the wind of my network from the parameters of the dynamic load.
Известно устройство дл определени прочностных характеристик грунта в услови х трехосного сжати , включающее станин1у, рабочую камеру с эластичной оболочкой дл Oi6pa3ua грунта, возбудитель давлени , нагрузочное приспособление с камерой давлени , силовой плитой и замкнутой гидросистемой. На таком устройстве невозможно исследовать зависимость прочностных характеристик грунта от Параметров динамической .нагрузки в сочетании со статической, что необходимо дл оценки несущей способности -грунта при возведении фундаментов в районах с повышенной сейсмической опасностью, а также подверженных вибраци м и сотр сени м от иных прдагин.A device for determining the strength characteristics of a soil under three-axis compression conditions is known, which includes a stand, a working chamber with an elastic shell for soil Oi6pa3ua, a pressure agent, a load device with a pressure chamber, a power plate and a closed hydraulic system. On such a device, it is impossible to investigate the dependence of the strength characteristics of the soil on the Dynamic Load Parameters in combination with the static one, which is necessary for assessing the carrying capacity of the soil during the construction of foundations in areas with increased seismic hazard, as well as vibrations and stress-prone ones from other sources.
Цель изобретени - обеспечить воз.можность создани дин:амической нагрузки при испытании.The purpose of the invention is to ensure the possibility of creating a din: amic load test.
Достигаетс это тем, что нагрузочное приспособление выполнено с гидропульсадионной ка.мерой, в которой установлен с возможностью вертикального перемещени щток, взаимодействующий с эксцевтричньим барабаном, соединенным с приводом вращени и смонтированным с возможностью горизонтального перемещени посредством винта, укрепленного на станиие. На чертеже изобг;ажено устройство дл определеннк прочностных характеристик грунта в услови х трехосного сжаТ1 , общий вид.This is achieved by the fact that the load device is made with a hydropulse gauge in which it is mounted with the possibility of vertical movement of the jaws, which interacts with an extramural drum connected to the rotational drive and mounted with the possibility of horizontal movement by means of a screw fixed to the stanie. The drawing shows a device for determining the strength characteristics of the soil under conditions of three-axis compression, T1, a general view.
Устройство включает станину /, рабочую 2 с эластичиои оболочкой дл образца гоунта 3, возоудитель давлени , на.цример, балло.н 4 со сжатым газом, нагрузочное приспособлб 11не с подвесным грузом, камерой 5 давлени , силовой плитой 6, Замк;1утой гидросистемой 7. гидрог.ульсационной Камерой S, в которой установлен шток 9, взаимоде11ствующий с эксцеитричпЫ;М барабаном 10, .соединенным с призсдом // вращени и смон:тированным с возможностью горизонтального перемещени посредством винта 12, укрецленного на станине /. Мзме.реиие производ т манометром 13, измер ющим статическое давление в гидросистеме, индикатором 14 деформаций образца от статической нагрузки, датчиком /5 динамических перемеи1ений, динамометром 16 дл )гзмереии осевой нагрузки и датчиком 17 величины амплитуды дииам-ической нагрузки.The device includes a frame /, a working 2 with an elastic sheath for a sample of gonta 3, a pressure generator, na rimer, balo n 4 with compressed gas, a load device 11 not with a suspended load, a pressure chamber 5, a power plate 6, Lock; by the first hydraulic system 7 hydrogensive chamber S, in which the rod 9 is installed, which interacts with the eccentricity; M drum 10, connected to the cartridge // rotation and mounted: can be horizontally displaced by means of the screw 12 fixed on the base /. A measurement is made by a manometer 13 measuring the static pressure in the hydraulic system, an indicator 14 of the sample deformations from a static load, a sensor / 5 dynamic interlaces, a dynamometer 16 for d) axial load measurements and a sensor 17 for the amplitude of the diagonal load.
Устройство дл определени црочностных характеристик грунта работает следующим образом.A device for determining the ground characteristics of the soil works as follows.
В эластичную оболочку помещают образецA sample is placed in an elastic sheath.
