Description
Изобретение касаетс устройств, позвол ющих изучать взаимодействие фундамента (сваи) с основанием из промерзающих и многолетнемерзлых грунтов.The invention relates to devices that allow the study of the interaction of the foundation (piles) with the foundation of freezing and permafrost soils.

В известных устройствах наблюдаютс значительные искажени в показани х прибора при передаче усилий, возникающих при взаимных перемещени х кольца и сердечника.In the known devices, there are significant distortions in the readings of the device during the transmission of forces arising from the mutual displacements of the ring and core.
В предложенном устройстве эти искажени уменьщаютс в результате нового конструктивного выполнени соединени сердечника с кольцом.In the proposed device, these distortions are reduced as a result of a new constructive implementation of the connection of the core with the ring.
На фиг. 1 изображено предложенное устройство дл определени сил смерзани , пучени и давлени на острие сваи, вид сбоку; на фиг. 2 - то же, поперечный разрез по А-А; на фиг. 3 - то же, продольный разрез по Б-Б.FIG. 1 shows the proposed device for determining the freezing forces, heaving and pressure on the tip of the pile, side view; in fig. 2 - the same, cross-section along A-A; in fig. 3 - the same longitudinal section through BB.
Устройство представл ет собой круглую полую сваю, состо щую из железобетонных колец /, разделенных между собой резиновыми прокладками 2, имеющую железобетонный сердечник 3, соединенный с железобетонными кольцами / при помощи опорных металлических балок 4, заделанных жестко в сердечнике и опертых щарнирно консольными выпусками на обнаженную арматуру 5 железобетонного кольца /The device is a circular hollow pile consisting of reinforced concrete rings / separated by rubber pads 2, having a reinforced concrete core 3 connected to reinforced concrete rings / by means of supporting metal beams 4 embedded rigidly in the core and supported with hinged cantilever gussets on the exposed reinforcement 5 reinforced concrete rings /
Устройство снабжено тензодатчиками 6 дл измерени деформаций и термисторами 7 дл определени температур. The device is equipped with strain gauges 6 for measuring deformations and thermistors 7 for determining temperatures.
Датчики 6 наклеиваютс на верхних и нижних гран х балок 4Этим обеспечиваетс температурна компенсаци и увеличиваетс вдвое выходной электрический сигнал. Проводники от датчиков припаиваютс к проводам кабел 8. Термисторы 7 укрепл ютс на внутренней поверхности колец /, провода от них припаиваютс к провода.м кабел 9.The sensors 6 are glued on the upper and lower edges of the beams 4. This provides temperature compensation and the electrical signal is doubled in output. The conductors from the sensors are soldered to the wires of the cable 8. The thermistors 7 are fixed on the inner surface of the rings, and the wires from them are soldered to the wires of the cable 9.
Устройство после сборки устанавливаетс в предварительно npo6vрс1П1ую скважину, залолненную пульпой 10.The device after assembly is installed in a pre-npo6vpc1P1 well filled with pulp 10.
Устройство снабжено двум мессдозам 11 и 12, позвол юпи1мч взвешивать внепгпюю нагрузку с точностью до 0,1 т.The device is equipped with two processors 11 and 12, which allows us to weigh the out-of-load load with an accuracy of 0.1 t.
