Description
Technical field
The utility model relates to waterproof roll experimental technique field, specifically a kind of new type waterproof coiled material compression test device.
Background technology
Waterproof roll is mainly used for construction wall, roofing, and tunnel, highway, refuse landfills etc. are located, play and resist extraneous rainwater, a kind of flexible building material product that is curled into web-like of ground water seepage, be connected as ne-leakage between engineering foundation and buildings, it is the first barrier of whole engineering waterproofing, whole engineering is played to vital effect, product mainly contains asphalt water-proof coiled material and polymer membranes, waterproof roll requires to have good water tolerance, to the stability of temperature variation, under high temperature, do not trickle, non-foaming, do not confuse, not embrittlement under low temperature, waterproof roll will have certain physical strength, extensibility and resistance to fracture, especially compression performance, it refers to that waterproof roll bears a constant load, stress or the performance not rupturing under the condition of certain distortion, do not have at present the special compression performance to waterproof roll to test, because the compression performance of waterproof roll can not be grasped in time, can not judge in time the compression performance performance index of coiled material, affect the performance of product.
Therefore, design and can test detection to the compression performance of waterproof roll for overcoming the deficiency of above-mentioned technology, grasp in time the technical indicator of the compression performance of coiled material, ensure a kind of new type waterproof coiled material compression test device of product quality, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of new type waterproof coiled material compression test device, it is simple in structure, easy to use, can test detection to the compression performance of waterproof roll, the technical indicator of grasping in time the compression performance of coiled material, ensures product quality, has extraordinary practical value.
The utility model solves the technical scheme that its technical matters adopts: a kind of new type waterproof coiled material compression test device, it is characterized in that: device comprises upper cover, piston, sample cap, permeable stone, organic glass cylinder, rubber membrane, sample chamber, rubber band, draining valve, base, described organic glass cylinder top is provided with upper cover, upper cover inside middle is provided with the piston through upper cover, piston base is connected with sample cap, sample cap bottom is provided with permeable stone, sample cap is embedded into sample chamber top, sample chamber outer setting has rubber membrane, sample chamber bottom is arranged on base, floor installation is in organic glass cylinder bottom, sample chamber bottom is provided with rubber band.
Further, described base bottom is provided with air compressor machine interface, and air compressor machine interface is connected with organic glass cylinder.Further, described base bottom is provided with hole stress measurement interface, and stress measurement interface in space is connected with sample chamber.
Further, described permeable stone is also connected with draining valve, and draining valve is arranged in base.
The beneficial effects of the utility model are:
1, by using this device to test detection to the compression performance of waterproof roll, grasp in time the technical indicator of the compression performance of coiled material, ensure product quality, have extraordinary effect.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is a kind of new type waterproof coiled material compression test of the utility model apparatus structure schematic diagram, device comprises upper cover 1, piston 2, sample cap 3, permeable stone 4, organic glass cylinder 5, rubber membrane 6, sample chamber 7, rubber band 8, draining valve 9, base 10, described organic glass cylinder 5 tops are provided with upper cover 1, upper cover 1 inside middle is provided with the piston 2 through upper cover 1, piston 2 bottoms are connected with sample cap 3, sample cap 3 bottoms are provided with permeable stone 4, sample cap 3 is embedded into sample chamber 7 tops, sample chamber 7 outer setting have rubber membrane 6, sample chamber 7 bottoms are arranged on base 10, base 10 is arranged on organic glass cylinder 5 bottoms, sample chamber 7 bottoms are provided with rubber band 8.
Base 10 bottoms are provided with air compressor machine interface 11, and air compressor machine interface 11 is connected with organic glass cylinder 5, and base 10 bottoms are provided with hole stress measurement interface 12, and stress measurement interface 12 in space is connected with sample chamber 7.
The utility model is waited in use, waterproof roll is enclosed within rubber diaphragm, be placed in the sample chamber 7 of sealing, then in sample chamber 7, be pressed into water, make waterproof roll be subject to ambient pressure in all directions, and hydraulic pressure is remained unchanged in whole process of the test, at this moment in test specimen respectively to three principle stresses all equate, therefore there is not shear stress, and then by transmission rod, waterproof roll is applied to vertical pressure, like this, vertical principle stress is just greater than level to principle stress, when level remains unchanged to principle stress, and vertical principle stress is while increasing gradually, waterproof roll is finally cut and is destroyed, if the vertical compressive stress being added on test specimen by transmission rod when shear failure is Δ σ 1, the large principle stress on test specimen is σ 1=σ 3+ Δ σ 1, and minor principal stress is σ 3, can draw a ultimate stress circle taking (σ 1-σ 3) as diameter, test respectively by the above method with several test specimens of same sample, each test specimen applies different ambient pressure σ 3, large principle stress σ 1 can draw shear failure respectively time, these results are plotted to one group of ultimate stress circle.Because these test specimens are all trimmed to destruction, according to Mohr Coulomb's theory, make the common tangential of one group of ultimate stress circle, be the shearing strength envelope curve of waterproof roll, conventionally can be similar to and be taken as straight line, the angle of this straight line and horizontal ordinate is the angle of internal friction ψ of waterproof roll, and the intercept of straight line and ordinate is the cohesion c of waterproof roll.
Outstanding advantages of the present utility model is the variation that can comparatively strictly control drainage condition and can measure test specimen Pore Pressure, in addition, stress state in test specimen is also clearer and more definite, the plane of fracture is at the weakest point, and unlike direct shear apparatus, be limited between upper and lower box, by using this device to test detection to the compression performance of waterproof roll, grasp in time the technical indicator of the compression performance of coiled material, ensure product quality, have extraordinary effect.
