Abstract
The utility model discloses an anti-washout test device for an inorganic binder stabilizing material. The anti-washout test device comprises a washout barrel, wherein a base is fixed on the bottom surface in the washout barrel; a clamp is vertically arranged on the base; a rubber sleeve is arranged in the clamp and is cylindrical; the diameter of the rubber sleeve is identical to that of a test piece; and the height of the rubber sleeve is smaller than that of the test piece. When the device is used in an anti-washout test on the inorganic binder stabilizing material, the test piece structure below the top of the test piece cannot be washed-out, only the top of the test piece is subjected to a washout environment which accords with an authentic condition of a road surface environment, so that the phenomena that in a conventional test method, the lower side part of the test piece suffers from current scour, and a test piece material is peeled off are improved, and a test result accords with a practical situation; and the device is simple in structure and practical in function.
Description
Technical field
The utility model relates to a kind of test unit, is specifically related to a kind of stabilized with inorganic binder material antiscour test unit, is mainly used in laboratory antiscour strength test.
Background technology
Stipulate according to " highway engineering stabilized with inorganic binder material test rules (JTG E51-2009) ", when measuring stabilized with inorganic binder material antiscour intensity, the material that will measure need to be made into cylinder specimen, then utilize existing instrument to carry out washout test.Under actual conditions, pavement structure is the souring that superficial layer is subject to water.But, while utilizing existing instrument to test, due to the protection that lacks the test specimen downside; under the souring of water, may cause test specimen downside material to drop, it is larger than truth that this will make material wash away the amount of dropping; thereby make measurement result inaccurate, large with the actual conditions deviation.
Summary of the invention
For above-mentioned weak point of the prior art, the purpose of this utility model is, propose a kind of stabilized with inorganic binder material antiscour test unit that is mainly used in laboratory, make test specimen downside in the process of test avoid washing away, make measurement result more accurate.
In order to realize above-mentioned task, the technical scheme that the utility model adopts is:
A kind of stabilized with inorganic binder material antiscour test unit, comprise and wash away bucket, be consolidated with base on bottom surface in washing away bucket, vertically be provided with fixture on base, be provided with leather sheath in fixture, described leather sheath is cylindric rubber sleave, and the diameter of leather sheath is identical with the test specimen diameter, and the height of leather sheath is less than the height of test specimen.
Preferably, the bottom surface diameter of described leather sheath is 150mm, the high 120mm of leather sheath.
The beneficial effects of the utility model are:
This device is when carrying out the test of stabilized with inorganic binder material antiscour, the following test specimen structure in test specimen top can not washed away, only the test specimen top is in and washes away in environment, conform to the road environment truth, thereby improved test specimen following side in original test method and suffered current scour, the phenomenon that material for test peels off, test findings conforms to actual conditions; This apparatus structure is simple, practical function.
Description of drawings
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is the structural representation of fixture and leather sheath part;
The number in the figure representative: 1-bucket washed away, 2-pressure head, 3-clear water, 4-test specimen, 5-leather sheath, 6-fixture, 7-base;
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Defer to technique scheme, as depicted in figs. 1 and 2, the present embodiment provides a kind of stabilized with inorganic binder material antiscour test unit, comprise and wash away bucket 1, be consolidated with base 7 on the bottom surface in washing away bucket 1, vertically be provided with fixture 6 on base 7, be provided with leather sheath 5 in fixture 6, described leather sheath 5 is cylindric rubber sleave, and the diameter of leather sheath 5 is identical with test specimen 4 diameters, and the height of leather sheath 5 is less than the height of test specimen 4.
Due under the true road conditions environment, pavement structure only has surface part to be subject to washing away of water, and the following structure in road surface can directly not be subject to washing away of water, namely in simulation test, only has the upper part of test specimen 4 to be washed away, and the result of measurement more meets truth.And in existing process of the test, lack the protection to test specimen 4 end portions, and therefore under the souring of water, may cause test specimen 4 downside materials to drop, it is larger than truth that this will make material wash away the amount of dropping, and causes measurement result inaccurate.
For this situation, in the utility model, designed the leather sheath 5 that is used for parcel test specimen 4, because test specimen 4 be cylindrical, so leather sheath 5 also is designed to cylindrically, and its diameter is identical with test specimen 4 diameters, and it is highly less than test specimen 4 highly; Leather sheath 5 adopts rubber sleave 5, and waterproof and flexible, can tightly wrap test specimen 4 lower ends, and only test specimen 4 upper parts be exposed; The fixture 6 in test specimen 4 outsides, when test specimen 4 is played clamping action, also can exert pressure to leather sheath 5, makes leather sheath 5 can more closely wrap up test specimen 4.
Because the specification of standard specimen is: diameter 150mm, high 150mm; Therefore in the present embodiment, preferred leather sheath 5 specifications are: 150mm, high 120mm, make test specimen 4 tops have 30mm out exposed, in order to carry out washout test.
Concrete use procedure of the present utility model is as follows:
At first, the test specimen 4 of full water is taken out from water, wipe away dried surface moisture, claim to obtain quality m
0Leather sheath 5 is enclosed within test specimen 4 outsides, make leather sheath 5 bottoms equal with test specimen 4 bottoms, then test specimen 4 is put into and washed away bucket 1, and with fixture 6, be fixed on and wash away bucket 1 bottom surface, then will wash away bucket and 1 be placed on testing machine, inject clear water 3 in bucket, the water surface is higher than test specimen 45mm, the rubber gasket on test specimen 4 top pads.Adjust the application of force state of testing machine, utilize the pressure head 2 of testing machine to exert pressure to test specimen 4 tops, the impulsive force peak value is 0.5MPa, and washing away frequency is 10Hz, flushing time 30min.After washing away end, will wash away bucket 1 and unload, down wash is carefully poured in basin, precipitation 12h, pour out clear water in basin 3,, with remaining sediment oven dry, claims to such an extent that quality is m
f, can calculate and wash away mass loss p by following formula:
