Description
(54) ИНДИКАТОРНЫЕ КЛЕЩИ ДЛЯ ОПРЕДЕЛЕНИЯ ПРОЧНОСТИ(54) INDICATOR MICKS FOR DETERMINATION OF STRENGTH
МЕРЗЛЫХ ГРУНТОВFROZEN GROUNDS
. I .. I.
Изобретение относитс костройтельству и, в частности, к устройствам дл определени прочностных характеристик мерзлых грунтов в полевых услови х.The invention relates to construction and, in particular, to devices for determining the strength characteristics of frozen soils under field conditions.
Известен пенетрометр, включающий наконечник со штаНгой и измерительное приспособление |l .A penetrometer is known, including a tip with a rod and a measuring device | l.
Наиболее близкими к изобретению по технической сущности и достигае метлу результату вл ютс индикаторные кле1аи, содёржааде рычаги, поггрузочное устройство в виде корпуса с пружиной и индикатор 2.The closest to the invention according to the technical nature and reaching the broom result are indicator tapes, levers, a body loading device with a spring, and an indicator 2.
Недостатком их вл етс невозможность обеспечени комплексного испытани на статическую и динамическую нагрузки.Their disadvantage is the impossibility of providing a comprehensive test for static and dynamic loads.
Цель изобретени - обеспечение проведени комплексных испытаний на статическую и динамическую нагрузки .The purpose of the invention is to provide complex tests for static and dynamic loads.
Это достигаетс тем, что в индикаторных клещах, содержащих рычаги, нагрузочное устройство в виде корпуса с пружиной и индикатор, нагрузочное устройство снабжено жестко прикрепленным к корпусу пружинным молотком и в заимодействуютим с ним этауюнн1 4 стержнем, бокова поверхностьThis is achieved by the fact that in the indicator tongs containing levers, the load device in the form of a housing with a spring and an indicator, the load device is equipped with a spring hammer rigidly attached to the case and, in borrowing with it, a rod
которого в верхней части выполнена в виде храповой гребенки, причем пружинный молоток выполнен в виде стальной пружины с пригрузом.which in the upper part is made in the form of a ratchet comb, and the spring hammer is made in the form of a steel spring with weights.
На чертеже изображено предлагаемое устройство в разрезе, общий вид.The drawing shows the proposed device in section, General view.
Устройство состоит из корпуса 1 с циферблатом, площадки 2, верхнего рычага 3, нижнего рычага 4, гильзы The device consists of a case 1 with a dial, pad 2, upper lever 3, lower lever 4, sleeves
0 5 с зубчатой рейкой, пружины 6, эталонного стержн 7, бокова поверхность которого выполнена в виде храповой гребенки, на буртик которого опираетс гильза 5, направл ющей 0 5 with a toothed rack, springs 6, reference rod 7, the lateral surface of which is made in the form of a ratchet comb, on the shoulder of which the sleeve 5 rests
5 втулки 8, пружинного молотка 9, зубчатого сектора со стрелкой 10, визирной стрелки 11, двух стопорных шайб 12, оси 13 зубчатого сектора, осей .14 рычагов 1слещей.5 sleeve 8, spring hammer 9, the toothed sector with the arrow 10, the sighting arrow 11, two lock washers 12, the axis 13 of the toothed sector, the axes .14 of the levers 1 of the slider.

Дл определени сопротивлени испытуемого образца требуетс кусок грунта, доведенный до заданной толщины , положить на площадку 2 и рычаги 3 и 4 клещей до полного To determine the resistance of the test specimen, a piece of soil, brought to a given thickness, is required, put on the pad 2 and the levers 3 and 4 ticks to the full
5 внедрени эталонного-стеркн 7 в мае су испытуемого образца.5 of the introduction of the reference-Stern 7 in May of the test sample.
Ори этом на шкале корпуса 1 стрелка IО зубчатого сектора показывает какое максимальное сопротивление было преодолено при внедрении эталонногоOn this scale, on the scale of the housing 1, the arrow IO of the toothed sector shows what maximum resistance was overcome when introducing the reference
