Description

Изобретение относитс  к устройствам дл  испыта.ни  грунта на срез в натурных услови х .The invention relates to a device for testing soil for cutting under natural conditions.

Известное устройство такого назначени  включает составную но высоте штангу со сниральным буром на конце и руко тку с измерительными приснособленн мн.The known device of such designation includes a composite but height rod with a bore hole at the end and a handle with measuring devices plural.

Цель изобретени  - повысить точность определени  усили  среза. Дл  этого штанга устройства в своей верхней части выполнена с жимком, опертым на упорный подшипник, ограничиваюш.ий поступательное движение штанги.The purpose of the invention is to improve the accuracy of determining shear forces. For this, the boom of the device in its upper part is made with a press supported on a thrust bearing, limiting the forward movement of the boom.

На чертеже схематично изображено описываемое устройство.The drawing schematically shows the described device.

Составна  штанга устройства состоит из соединенных между собой звеньев /. К одному концу штанги присоединен спиральный бур 2, а на другом конце имеетс  руко тка 3 с измерительными приспособлени ми и жимок 4, который служит дл  погружени  в грунт бура 2.The integral bar of the device consists of interconnected links. A spiral auger 2 is attached to one end of the rod, and at the other end there is a handle 3 with measuring devices and a press 4, which serves to immerse a drill 2 in the ground.

Жимок опираетс  на упорный подшипник 5, помещенный в обойме 6, служащей дл  передачи осевого усили , возникающего при проведении среза грунта, на лежни 7.The supports are supported by a thrust bearing 5, placed in the holder 6, which serves to transfer the axial force arising during the cutting of the soil to the bed 7.

В подготовленную скважину опускают штангу 8 с буром и, нажима  на руко тки жимка 4, вращают спиральный бур. При вращении бура, в зависимости от нлотности грунта , необходимо сообщать жимку вертикальное усилие, стрем сь погрузить бур на полную глубину за 3,5-4 оборота.A boom 8 with a drill is lowered into the prepared well and, pressing the knobs 4, rotates the spiral drill. When the drill is rotated, depending on the soil density, it is necessary to report the vertical tension force, trying to load the drill to its full depth in 3.5-4 turns.

После погружени  бура на глубину h жимок онускают на крышку обоймы и в этом положении зажимают на штанге. Затем устанавливают в рабочее положение руко тку и начинают медленно ее вращать, наблюда  за величиной усили  среза После того как произойдет срез грунта и будет определено максимальное значение усили  среза, производ т дополнительно 2-3 оборота прибора дл  определени  сопротивлени  трению в грунте нарушенной структуры. Зна  величину усили  нри срезе грунта, онредел ют величину крут щего момента.After the drill is submerged to the depth h of the jig, it is pressed onto the cage cover and in this position is clamped onto the rod. Then the handle is set in the working position and slowly rotate it, observing the magnitude of the shearing force. After the soil is cut and the maximum value of the shear force is determined, an additional 2-3 turns of the device are made to determine the resistance to friction in the soil of the damaged structure. Knowing the magnitude of the force when cutting the soil, it determines the magnitude of the torque.

При работе в грунтах м гкопластичной, текучепластичной и текучей консистенции и частично в грунтах тугонластичной консистенции испытание на срез можно проводить безWhen working in soils of a soft plastic, flowable and flowing consistency and partially in soils of a tug of elastic consistency, the cut test can be carried out without

Скважину бур т самим устройством дл  испытани  грунта на срез. производ  срез грунта на любой заданной глуПредмет изобретени well drilling with a separate drilling set. The operation in this case is performed as follows. The well is drilled by the cutting device itself. making a cut of the soil on any given depth

Устройство дл  испытани  грунта на срез в натурных услови х, включаюш,ее составную по высоте штангу со сниральным буром на конце и руко тку с измерительными приспособлени ми , отличающеес  тем, что, с целью повышени  точности определени  усили  среза , штанга устройства в своей верхней части выполнена с жимком, опертым на упорный подшипник, ограничивающий поступательное движение штанги.A device for testing soil for shearing in natural conditions, including its height bar with a carriage drill at the end and a handle with measuring devices, characterized in that, in order to improve the accuracy of determining shear force, the bar of the device in its upper part made with a clamp, supported on a thrust bearing, limiting the translational movement of the rod.
