Description

Изобретение относитс  к приборам дл  определени  просадочных свойств лессовых грунтов, состо щим из обоймы, заполн емой испытуемым грунтом, установленной на дырчатый поддон, дырчатой крышкиштампа , смачивающего устройства и измерительной аппаратуры.The invention relates to devices for determining the subsidence properties of loess soils, consisting of a holder filled with the test soil, installed on a perforated tray, a perforated shroud cover, a wetting device and measuring equipment.

Известные такого рода приборы имеют приспособлени  дл  уплотнени  грунта в виде рычажного механизма, передающего нагрузку на крышку-штамп.Known devices of this kind have devices for soil compaction in the form of a lever mechanism that transfers the load to the cover-stamp.

В предлагаемом приборе, с целью упрощени  такого приспособлени , крышка-штамп присоединена к штоку поршн  резервуара, в котором помещен баллон из эластичного материала, соединенный трубопроводом с источником питани  сжатым воздухом, например с воздухосборником компрессора, и оказывающий давление на поршень дл  уплотнени  испытываемого грунта.In the proposed device, in order to simplify such a device, the cover-stamp is connected to the piston rod of the tank, in which a cylinder of elastic material is placed, connected by a pipeline to a compressed air supply source, such as a compressor air collector, and exerts pressure on the piston to seal the test soil.

На чертеже изображена схема предлагаемого прибора.The drawing shows a diagram of the proposed device.

Прибор дл  определени  просадочных свойств лессовых грунтов состоит из сменной обоймы /, заполн емой испытуемым грунтом 2. Обойма устанавливаетс  на дырчатый поддон 3, помещенный в стакане 4. Полость 5 под поддоном присоединена к бачку 6 с водой дл  смачивани  образца грунта и имеет спускной кран7.A device for determining the subsidence properties of loess soils consists of a replaceable holder / filled with test soil 2. The holder is mounted on a perforated tray 3 placed in glass 4. Cavity 5 under the tray is attached to the water tank 6 for wetting the soil sample and has a drain valve 7.

Сверху на испытываемый образец грунта воздействует крышкаштамп 8, соединенна  со штоком поршн  9, помещенного в резервуаре JO. В полости резервуара, расположенной над поршнем, помещен баллон 11 из эластичного материала, соединенный трубопроводом с источником питани  сжатым воздухом-воздухосборником 12 компрессора 13 и контрольным манометром 14. К баллону присоединена также трубка 15 со спускным краном.On top of the test sample of the soil affects the cover punch 8, connected to the piston rod 9, placed in the reservoir JO. In the cavity of the tank located above the piston, a cylinder 11 of elastic material is connected by a pipeline to a power source with compressed air by the air collector 12 of compressor 13 and a test pressure gauge 14. A tube 15 with a drain valve is also attached to the cylinder.

Благодар  применению баллона отпадает надобность в усгронстве сальников.Due to the use of the balloon, there is no need for packing up the glands.

В св зи с применением сменных обойм, на описываемом арнборе могут испытыватьс  образцы грунта различных диаметров.In connection with the use of interchangeable clips, soil samples of various diameters can be tested on the arbor described.

. Предмет изобретени . Subject invention

Прибор дл  определени  просадочных свойств лессовых грунтов,. состо ш;ий из обоймы, заполн емой испытуемым грунтом, установленный на дырчатый поддон, дырчатой крышки-штампа, смачива1ош,его устройства и измерительной аппаратуры, отличаюш;ийс  тем, что, с целью упрощени  конструкции его, крышка-штамп присоединена к штоку поршн  резервуара, в котором помещен баллон из эласткчного материала, соединенный трубопроводом с источником питани  сжатым воздухом, например с воздухосборником компрессора, и оказыоа1.)щий давление на поршень дл  уплотнени  испытываемого грунта.A device for determining the subsidence properties of loess soils. composed of a clip, filled with a test soil, mounted on a perforated tray, a perforated stamp cover, wetted, its devices and measuring equipment, distinguished by the fact that, in order to simplify its design, a cover – stamp is attached to the piston rod a tank in which a cylinder of elastic material is placed, connected by a pipeline to a power source with compressed air, such as a compressor air collector, and putting pressure on the piston to seal the test soil.
