Description
(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ СВЯЗНОГО ГРУЛТА(54) DEVICE FOR TESTING THE CONNECTED GRADE
Изобретение относитс к области .исследований прочностных и деформационных характеристик глинистых материалов и вл етс усовершенствование известного устройства, описанного в авторском свидетельстве .f 491080.The invention relates to the field of research into the strength and deformation characteristics of clay materials and is an improvement to the known device described in the author's certificate .f 491080.
В основном изобретении по авторскому свидетельству № 491080 описано устройство дл св зного грунта, используемое преимутцественно дл определени раст жимости и прочности св зных грунтов при реологических исследовани х в услови х их нагружени . Это устройство содержит камер высокого давлени с крышками и внутренней оболочкой, центрирующее приспсобление , источник давлени и измерительные приборы. Центрирующее приспособление выполнено с винтовым домкратом и стержнем, имеющим нагрузочную подвеску и- прикрепленным к нижней крышке, а шток винтового домкрата установлен в верхней крышке камеры и в него вмонтирован датчик порового давлени . На концах штока и стержн расположенных в камере , закреплены захваты например цилиндрической 1.The basic invention in accordance with the author's certificate No. 491080 describes a device for bonded soil, which is mainly used to determine the tensile strength and strength of bonded soils during rheological studies under the conditions of their loading. This device contains high-pressure chambers with lids and an inner casing, a centering device, a pressure source and measuring instruments. The centering device is made with a screw jack and a rod that has a load suspension and is attached to the bottom cover, and the screw jack shaft is installed in the top cover of the chamber and a pore pressure sensor is installed in it. At the ends of the rod and rod located in the chamber, fixed grippers such as cylindrical 1.
Известное устройство позвол ет определить величину ползучести иThe known device allows to determine the creep value and
раст жени грунта в услови х трехосного сжати , однако оно не может быть использовано дл изменени релаксации раст гивающих напр жений в услови х сложного напр женного состо ни образца . soil stretching under conditions of triaxial compression; however, it cannot be used to alter the relaxation of tensile stresses under conditions of a complex stress state of the sample.
Цель изобретени - определение релаксации раст гивающих напр жений св зного грунта в услови х сл.ож0 ного напр женного состо ни .The purpose of the invention is to determine the relaxation of the tensile stresses of the bonded soil under the conditions of a recent stress state.
Данна цель достигаетс тем, что устройство дл испытани св зного грунта по авторскому свидетельству № 491080 снабжено расположенной под стержнем опорной рамой и монтирован- НЫГ4 на ней соосно стержню дополнительным домкратом, причем один из измерительных приборов в виде измерител силы смонтирован на штоке винтового домкрата.This goal is achieved by the fact that the device for testing the bonded soil according to the author's certificate No. 491080 is equipped with a support frame located under the rod and mounted with NYG4 on it coaxially with an additional jack, one of the measuring instruments in the form of a force meter mounted on a screw jack stem.
