Abstract
The utility model belongs to a three-axes test device, particular relates to a three-axes test confined pressure loading barrel, composed of a pressure barrel (1) and a rubber film (4). An oil hole (1-1) is provided at the wall of the pressure barrel (1), an upper screw steel ring (3) is screw-connected at the upper end of the pressure barrel (1), a lower screw steel ring (6) is screw-connected at the lower end, an upper pressing head (2) is movably mounted in a center hole of the upper screw steel ring (3), removing holes (9) are provided on end faces of the upper screw steel ring (3) and the lower screw steel ring (6), the upper end of the upper pressing head is made in an arc shape. The loading barrel has simple and rapid operation during used as a member to be tested in a three-axes test without hands touching oil, and obtains good testing effect.
Description
Technical field
The utility model belongs to the triaxial test device, and particularly a kind of triaxial test confined pressure loads tube.
Background technology
At present, the triaxial cell be manually test specimen with after rubber diaphragm sealed, put into pressure oil, allow the test specimen all directions all be subjected to the effect of confined pressure, complicated operation often needs hand to be dipped in the oil, promptly the trouble very dirty again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple to operate, quick, and hand is immersion oil not, and the triaxial test confined pressure that experiment effect is good loads tube.
The technical scheme that the utility model technical solution problem adopts is: a kind of triaxial test confined pressure of being made up of pressure measuring cylinder, rubber diaphragm loads tube, be characterized on the pressure barrel, establishing an oilhole, pressure cylindrical shell upper end snail line connects one and goes up the screw thread steel loop, the lower end following screw thread steel loop that is threaded, adorn a seaming chuck versatilely in the last screw thread steel loop center pit, arc is made in the seaming chuck upper end, is equipped with on last screw thread steel loop and the following threaded collar end face and removes the hole.
The beneficial effects of the utility model are: this loading tube is simple to operate when making the triaxial test of test specimen, quick, and hand is immersion oil not, and test effect is good.
