Abstract
The utility model discloses a frozen soil pressure resistance tester, which comprises a workbench and a testing area. A test block frame and a displacement sensor are disposed in the testing area, the test block frame is a circular projection arranged at the bottom of the testing area, the shape and the size of the circular projection of the test block frame match with the inner diameter of a test block, and the displacement sensor is arranged at a corresponding position on the outer side of the test block. As the test block frame and the displacement sensor are disposed in the testing area, the frozen soil test block can be fixed onto the test block frame, the displacement sensor is arranged at the corresponding position on the outer side of the test block, and then deformation of the tubular outer side of the frozen soil test block and pressure of damage of the frozen soil test block can be measured by means of pressurizing the tubular inside of the frozen test block. Therefore, the frozen soil pressure resistance tester has the advantages of simple structure, and is particularly suitable for pressure tests of tubular frozen soil test blocks. A pressurizing bag holder is arranged on the test block frame, and elastic bags are disposed on the pressurizing bag holder, thereby bringing convenience for operation during testing.
Description
Technical field
The utility model relates to a kind of Withstand test device, a kind of frozen soil pressure-resistant tester of more specifically saying so, dependent territory worker's test apparatus technical field.
Background technology
In infrastructural projects such as raising highway, particularly at north cold area, understand the parameters such as compressive resistance of the frozen soil under the highway pavement, will help improving construction quality.
The pressure test of frozen soil can be under the temperature of setting, and to the frozen soil piece of specific shape, under certain pressure, the pressure of the deflection of frozen soil piece and the breakage of frozen soil piece is measured.In general, the test temperature of frozen soil is-15 ℃, the frozen soil piece be shaped as tubulose, the external diameter of tubulose is 120 millimeters, internal diameter is 100 millimeters, length is 40 millimeters.Above-mentioned frozen soil piece is by to pressure in addition in the tubulose, and the deflection in the frozen soil piece tubulose outside and the pressure of frozen soil piece breakage are as the withstand voltage properties of frozen soil.At present, Shang Weiyou carries out the test apparatus of piezometry to the frozen soil piece of above-mentioned shape.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of simple in structure, frozen soil pressure-resistant tester of being suitable for tubulose frozen soil piece pressure test.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of frozen soil pressure-resistant tester, it comprises worktable and test section, be provided with test block frame and displacement transducer in the described test section, described test block frame is the circular protrusions that is arranged on the bottom, test section, the circular protrusions shape size of described test block frame is complementary with the internal diameter of test block, and described displacement transducer is at test block outside correspondence position.
Described displacement transducer quantity is three or four.The inflating bag frame has been set up in described test block, and described inflating bag frame is provided with flexible bag.
As improvement, above-mentioned frozen soil pressure-resistant tester, bottom, described test section is provided with the bar groove of normal direction, and described displacement transducer movable fixed is on the bar groove.
Owing to adopted said structure, owing to be provided with test block frame and displacement transducer in the test section of frozen soil pressure-resistant tester of the present utility model, the frozen soil test block can be fixed on the test block frame, displacement transducer is at test block outside correspondence position, by tubular inner pressurization, record the deflection in the frozen soil piece tubulose outside and the pressure of frozen soil piece breakage like this to the frozen soil test block.Therefore frozen soil pressure-resistant tester of the present utility model has characteristic of simple structure, is particularly suitable for tubulose frozen soil piece pressure test.Set up the inflating bag frame in test block, described inflating bag frame is provided with flexible bag, the operation when having made things convenient for test like this.What will replenish here is specifically can adopt by the flexible bag of aluminium glue is housed the tubular inner pressurization of frozen soil test block.As latex rubber bag of aluminium glue etc. is housed.
Description of drawings
Fig. 1 is the structural representation of the utility model frozen soil pressure-resistant tester;
Fig. 2 is the structural drawing in the test section.
Among the figure: 1-worktable, 2-test section, 3-test block frame, 4-test block, 5-displacement transducer, 6-bar groove, 7-inflating bag frame, 8-flexible bag.
Embodiment
As shown in Figure 1, frozen soil pressure-resistant tester of the present utility model, it comprises worktable 1 and test section 2.On the described worktable 1 display, controll block etc. can be installed, because these are similar with the test apparatus of prior art, therefore no longer expansion.Be provided with test block frame 3 and displacement transducer 5 in the described test section 2, described test block frame 3, described test block frame 3 is for being arranged on the circular protrusions of 2 bottoms, test section, and the circular protrusions shape size of described test block frame 3 is complementary with the internal diameter of test block 4, and described displacement transducer 5 is at test block 4 outside correspondence positions.Described displacement transducer 5 quantity are three or four, are example with four among the figure.
Described test block frame 3 is provided with inflating bag frame 7, and described inflating bag frame 7 is provided with flexible bag 8.
As improvement, 2 bottoms, described test section are provided with the bar groove 6 of normal direction, described displacement transducer 5 movable fixed are on bar groove 6, the structure that the structure of this movable fixed can adopt mechanical field to use always, as displacement transducer 5 and 2 bottoms, test section spring is set, displacement transducer 5 welt grooves 6 is moved as long as press down displacement sensor 5.
