Description

Известные приборы дл  определени  компрессионных, просадочных и -фильтрационных свойств грунтов рассчитаны на работу в стационарных лабораторных услови х. Во всех таких приборах дл  креплени  опорной части загрузочных рычажных приспособлений примен ютс  либо громоздкие металлические станины, либо жестко закрепленные в капитальных стенах лаборатории отрезки спаренных швеллеров, рельсов и т. п. Поэтому все эти приборы непригодны дл  работы в полевых услови х, непосредственно на месте производства разведочных работ.The known instruments for determining the compression, sinking and filtration properties of soils are designed to work in stationary laboratory conditions. In all such devices, either bulky metal beds or rigidly fixed segments of channel bars, rails, etc., are rigidly fixed in the main walls of the laboratory, for fastening the support part of the loading lever devices. Therefore, all these devices are unsuitable for work in the field, directly in place. production exploration.

Описываемый прибор дает возможность определ ть компрессионные , просадочные и фильтрационные свойства грунтов непосредственно на месте изысканий без транспортировки образцов в стационарную лабораторию , благодар  чему ускор етс  процесс испытани  и повышаетс  его точность.The described device makes it possible to determine the compression, subsidence and filtration properties of soils directly at the survey site without transporting samples to a stationary laboratory, thereby speeding up the testing process and increasing its accuracy.

Отличие описываемого прибора от известных заключаетс  в том, что он выполнен в виде установленной на опорной плитке гильзы из прозрачного или иного материала, предназначенной дл  помещени  в нее испытуемого образца грунта. Грунт сжимаетс  поршнем грузового рычажного механизма, прикрепл емого вместе с гильзой посредством зажимного приспособлени  к различным имеюо1,имс  в полевых услови х предметам (доска и т. п.).The difference between the described device and the known ones is that it is made in the form of a sleeve installed on a support tile from a transparent or other material designed to place a test specimen of soil in it. The soil is compressed by the piston of the cargo linkage mechanism, which is attached together with the sleeve by means of a clamping device to various objects, field objects (board, etc.).

На чертеже изображена обща  конструктивна  схема прибора с нестационарным креплением.The drawing shows a general structural diagram of the device with non-stationary fastening.

Опорна  часть прибора выполнена в виде легкого переносного зажимного устройства /, на котором установлена гильза 2. Гильза 2 заполнена образцом испытуемого грунта, который сжимаетс  поршнем 3 грузового рычажного механизма 4. Рычажный механизм вместе с гильзой прикрепл етс  посредством зажимного устройства / к различным предметам , например, к доске 5, скамье, табуретке или к другим вещам, имеющимс  в полевых услови х. Грунтова  вода под образец подаетс  из сосуда 6.The support part of the device is made in the form of a lightweight portable clamping device / on which sleeve 2 is installed. Sleeve 2 is filled with a sample of the test soil, which is compressed by the piston 3 of the loading mechanism 4. The lever mechanism together with the sleeve is attached by means of a clamping device / to various objects, for example to board 5, bench, stool, or other things that exist in the field. Ground water under the sample is supplied from vessel 6.

Гильза 2 изготовлена из прозрачного или иного материала и места ее сопр жени  с компрессионной частью прибора доступны непосредственному наружному контролю, благодар  чему исключаетс  неподдающеес  контролю в известных приборах проникновение воды (при испыт нии ) вдоль наружных стенок )-цльзы и внутреннего корпуса прибора .The sleeve 2 is made of transparent or other material and its interface with the compression part of the device is available for direct external control, thereby eliminating water penetration (under test) that is not controllable in the known devices along the outer walls of the instrument and the inner case.
