Abstract
The utility model discloses a pore diameter tester for wet sieving geotextile fabric. The pore diameter tester comprises a sieve, a vibrator, a water sprayer and a water collector, wherein a sample fixing frame is arranged inside the sieve; a geotextile fabric sample is fixed on the sample fixing frame when the pore diameter tester for the wet sieving geotextile fabric works; the water sprayer is arranged above the sieve; the water collector is arranged under the sieve; a filtering screen is arranged inside the water collector; a water outlet is formed in the bottom of the water collector; a connection pipeline is arranged between the water outlet and the water sprayer; a water pump is arranged on the connection pipeline. According to the pore diameter tester for the wet sieving geotextile fabric, because the water outlet is formed in the bottom of the water collector, the connection pipeline is arranged between the water outlet and the water sprayer, and the water pump is arranged on the connection pipeline, spraying water is obtained from the discharging water of the water collector, the internal recycle of water can be achieved, water source is saved, and meanwhile the test cost is saved.
Description
Technical field
The utility model relates to a kind of aperture test instrument of geotextile, is more specifically a kind of aperture test instrument of wet screening geotextile, belongs to earthwork test Instrument manufacturing technology field.
Background technology
Effective aperture is one of important performance indexes of geotextile, and it has influence on the performance such as water permeability, intensity of geotextile.Therefore, need to measure the effective aperture of geotextile, method for measuring be carried out in the effective aperture of geotextile and generally divide dry sieve method and wet screening.The effective aperture of measuring geotextile generally using do not add tension force individual layer geotextile sample as screen cloth, under the vibration frequency and amplitude of regulation, make grain composition sand by geotextile sample.Dry sieve method is not carrying out under water spray situation at grain composition sand, and wet screening is after grain composition sand is sprayed water, then makes it pass through geotextile sample.
The aperture test instrument of existing wet screening geotextile comprises sieve tool, Vib., perforated water spray and water collector, in sieve tool, is provided with sample fixed mount, and perforated water spray is above sieve tool, and water collector, below sieve tool, is provided with filter screen in water collector.During the work of aperture test instrument, sieve and on the sample fixed mount in tool, fix geotextile sample to be measured, in sieve tool, be also equipped with the grain composition sand corresponding with geotextile sample, under the situation of simultaneously carrying out at vibration and water spray, water and the sand sifting out fall into water collector, water is by the filter screen of water collector, and sand is on the filter screen of water collector.The aperture test instrument of the wet screening geotextile of said structure is owing to will constantly spraying water in work, and the easy like this waste that causes water resource increases experimentation cost simultaneously.
Utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind of aperture test instrument that can water-saving wet screening geotextile, saves experimentation cost simultaneously.
For achieving the above object, the utility model is by the following technical solutions: a kind of aperture test instrument of wet screening geotextile, it comprises sieve tool, Vib., perforated water spray and water collector, in described sieve tool, be provided with sample fixed mount, fixing geotextile sample on sample fixed mount during the aperture test instrument work of described wet screening geotextile; Described perforated water spray is above sieve tool, and described water collector, below sieve tool, is provided with filter screen in described water collector, and the bottom of described water collector is provided with water delivering orifice, between described water delivering orifice and perforated water spray, is provided with connecting tube, and described connecting tube is provided with water pump.
Adopt such scheme, the aperture test instrument of wet screening geotextile of the present utility model, because the bottom of water collector is provided with water delivering orifice, between described water delivering orifice and perforated water spray, be provided with connecting tube, described connecting tube is provided with water pump, and water spray obtains from the water outlet of water collector like this, can realize the interior circulation of water, saving water resource is saved experimentation cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the aperture test instrument of the utility model wet screening geotextile.
In figure: 1-sieves tool, 2-Vib., 3-perforated water spray, 4-water collector, 5-sample fixed mount, 6-geotextile sample, 7-filter screen, 8-water delivering orifice, 9-connecting tube, 10-water pump.
Embodiment
As shown in Figure 1, the aperture test instrument of wet screening geotextile of the present utility model, it comprises sieve tool 1, Vib. 2, perforated water spray 3 and water collector 4, in described sieve tool 1, is provided with sample fixed mount 5, fixing geotextile sample 6 on sample fixed mount 5 during the aperture test instrument work of described wet screening geotextile.Described perforated water spray 3 is above sieve tool 1, and described water collector 4, below sieve tool 1, is provided with filter screen 7 in described water collector 4.Because the aperture test instrument structure of the wet screening geotextile of said structure and prior art is similar, therefore only do simple description.
The feature of the aperture test instrument of wet screening geotextile of the present utility model is: the bottom of described water collector 4 is provided with water delivering orifice 8, between described water delivering orifice 8 and perforated water spray 3, is provided with connecting tube 9, and described connecting tube 9 is provided with water pump 10.
