Description

Предметом изобретени   вл етс  прибор дл  испытани  бетона па прочность путем разрушени  стеиок сква И|П1|, заранее сделаиио) в бетоае .The subject of the invention is an apparatus for testing concrete pa durability by breaking steaks Squi I | P1 |, in advance done) in concrete.

Особеииоетыо прибора, is от.чпчпе от известных приборов, построенni.iч на толг же ириипнпе,  в,1 етс  наличие песко,аьких, например, четырех , ножей, передающих усили  i; радиальном направлении от неитрг скважнны равномерно во все ст;:роиы .The special instrument, which is from the known devices, is built on the same pressure, for example, the presence of sand, like, for example, four knives, transmitting forces i; the radial direction from the oil well bore evenly in all st;: royy.

На фиг. 1 ноказан продольиьы разрез прибора; на фиг. 2--разрез lio Л/1 на фиг. 1.FIG. 1 but a longitudinal section of the device; in fig. 2 is a section lio L / 1 in FIG. one.

Прибор выполнен в виде труб.ки / со вставленным в нее сте11Ж11ем -. Одни конец 3 стержн , как и соответствующа  полость трубки /, илгеег форлу усеченной пирамиды, обраиц-мпюй большим основанием к. торцу трубки. Верхний конец стержн  снабжен головкой 4. В стенке трубки в иижией ее части имеютс  окна-ирорезп 5, в которых скольз ще установ .тены ножи 6. По образ 1он1ей труб1 а / сиабжеип нарезкой, па которую навинчена raiiKa 7.The device is made in the form of pipes. One end of 3 rods, as well as the corresponding cavity of the tube /, or the formula of a truncated pyramid, forms a small base with a large base to the end of the tube. The upper end of the rod is provided with a head 4. In the wall of the tube in its part there are windows-holes 5, in which the knives 6 are installed slidably.

Действие нрибора заклочлетс  в с.чедуюшем.Nribor action zaklochlets in the village.

В заранее нодготовленную в бетоне скваж1П1у, диаметр которой несколько больше диаметра трубки /, опускают прибор. Глуб1н-1а погруженн  прибора регулируетс  гайкой 7, котора  быть передвинута по нар -жной резьбе трубки /. В рабочем по,тол е1П1и прибора гайка опираетс  на бетон вокруг скважины.In advance prepared in the concrete borehole 1P1y, the diameter of which is slightly larger than the diameter of the tube /, lower the device. The depth of the submerged device is adjusted by a nut 7, which is moved along the thread of the tube. In working mode, the thickness of the tool is supported by the nut on the concrete around the well.

Верхп   часть трубки / скрепл етс  с приспособлеииел 8 в виде домкрата и т. п., снабжеипого сплонз epнтeлe .м (па .ертеже не показан). При 1 ыт гива1 ии стержн  / за головку 4 его нира п1дальный нижний коиец 3 cBOHiviii боковыми гран ми иажн.мает на ножи 6, которые, выход  из окон 5. приход т в соприкосновение с бетонными стенками скважины , передава  на rntx возрастающее усилие вплоть до скалываин  бетона стеиок. Усилие, иеобходимое д.т  разрушеии  стеиок, фиксируетс  сило1 змерите.тем.The upper part of the tube / is fastened with a jack 8, in the form of a jack, etc., which is provided with a type of spontal component of the interface (not shown in the drawing). With 1 test lead / rod / for the head 4 of his nira, the bottom bottom edge is 3 cBOHiviii with side edges that are important for knives 6, which exit from windows 5. come into contact with the concrete walls of the well, transmitting to rntx increasing force up to skalyvayon concrete steyok. The force required to destroy the steaks is fixed by force.
