Description

Известные штанговые гамма-зонды, предназначенные дл  измерени  плотности песчано-глинистых грунтов в процессе бурени  скважин, содержат размещенные в полом стержне малого, диаметра источник и индикатор гамма-излучений, разделенные экраном, и усилительную электронную схему.Known rod gamma probes designed to measure the density of sandy-clay soils in the process of drilling wells contain a gamma-radiation source and indicator located in a hollow rod of small diameter, and an amplifying electronic circuit.

Описываемый штанговый гамма-зонд отличаетс  от известных тем, что он размещен в корпусе, снабженном подвижной втулкой и двум  навинчйваюш;имис  головкамл, обеспечивающими .скольз щую носадку верхней части на штангу, а ннжней части - на гамма-зонд.The described gamma probe differs from the known ones in that it is housed in a housing equipped with a movable sleeve and two screwed on them, which provide a sliding nose of the upper part to the rod and the lower part to the gamma probe.

Така  конструкци  гамма-зонда дает возможность предупредить поломки полого стержн  нри введении его в грунт.Such a gamma probe design makes it possible to prevent the hollow rod from breaking when introduced into the ground.

Конструкци  гамма-зонда изображена на чертеже.The construction of the gamma probe is shown in the drawing.

Штанговый гамма-зонд состоит из трех основных частей: источника 1 гамма-излучений, приемника 2 тамма-излучений и подключенной к Приемнику 2 кабелем 3 усилительной электронной схемы 4. К выходу усилительной схемы 4 подключен кабель 5, выход щий на поверхность.The gamma probe probe consists of three main parts: a gamma-radiation source 1, a tamma-radiation receiver 2, and a cable 5 of the amplifying electronic circuit 4 connected to the Receiver 2 by the output of the amplifying circuit 4, the cable 5 that goes to the surface.

Между источником } и приемником 2 размещен свинцовый или стальной экран 6.Between the source} and the receiver 2 is placed a lead or steel screen 6.

Гамма-зонд размещен в корпусе 7, внутри которого находитс  втулка 8, укрепленна  на резиновом кольце 9. На корпусе 7 навинчены верхн   головка 10 и нижн   головка 1}.The gamma probe is located in the housing 7, inside of which there is a sleeve 8, mounted on the rubber ring 9. On the housing 7, the upper head 10 and the lower head 1} are screwed.

Зонд опускаетс  в буровую скважину 12 на щтангах 13. При задавливании зонда его полый стержень 14, снабженный наконечником 15, входит в грунт на глубину 1 -1,3 м. Внутренние диаметры головок 10 11 выбраны так, чтобы обеспечить скольз щую посадку верхней части корпуса на штангу 16, а его нижней части - на стержень 14 гамма-зонда. Дл  передачи усили , действующего на щтанги 13 стержню 14 зонда, служит переходник 17. Предотвращение продольного изгиба стержн  14 обеспечиваетс  втулкой 8. При нагрузкеThe probe is lowered into the borehole 12 on the bar 13. When the probe is pushed, its hollow rod 14, provided with a tip 15, enters the ground at a depth of 1-1.3 m. The internal diameters of the heads 10 11 are chosen so as to provide a sliding fit of the upper part of the body. on the rod 16, and its lower part - on the rod 14 of the gamma probe. An adapter 17 serves to transfer the force acting on the rod 13 to the probe rod 14. The rod 14 is prevented from buckling the rod 8. Under load
